Picture perfect: Driving next-generation image processing for automotive

Wednesday, April 26th, 2017

The automobile is no longer a metal box with four wheels that gets you from A to B. As technology has evolved, vehicles have become a dynamic platform for innovation which is changing the driver experience and taking us closer to the reality of truly autonomous driving. Advanced Driver Assistance Systems (ADAS) capabilities are integral to this evolution. New ADAS applications such as mirror replacement, driver drowsiness detection and pedestrian protection systems drive the need for enhanced image processing within the vehicle. Enabling these technologies requires an increasing number of cameras in vehicles, with most high end mass market vehicles expected to contain up to twelve cameras within the next few years, according to Strategy Analytics.

However, this type of complex camera technology must quickly process and analyze images under the most extreme conditions and be specifically designed for stringent automotive safety standards. Simply integrating standard camera technologies used in smartphones, or even consumer video cameras, is not an option. To address these challenges, today we’re launching the ARM Mali-C71 image signal processor (ISP), the first product in our Mali Camera family. The Mali-C71 was designed from the ground up for ADAS System on Chips (SoCs) with automotive needs such as adjusting for challenging lighting and weather conditions in mind.

High end vehicles could contain up to 10/12 cameras in the future

The changing role of the Image Signal Processor (ISP)

As the number of cameras per vehicle increases and sensor fusion technologies get smarter, the ISP function – processing raw pixels into high quality images for displays – encoding and further processing by computer vision algorithms is being centralised within the ADAS SoC. Therefore the SoC is capable of managing multiple cameras and delivering reliability and the highest levels of safety in the automotive market. This requires a new approach with built-in functional safety features and parallel virtual processing output for computer vision applications. To date, implementing this in a single SoC has been an elusive goal. Until now.

Mali-C71: Automotive grade clarity and reliability

Automotive cameras need to provide the highest possible levels of clarity and reliability. Where the camera output is generated for a display, image quality is paramount. Take for example mirror replacement, as shown in the image below. The Mali-C71 offers ultra-wide dynamic range (UWDR) up to 24 stops (in some cases, providing detail beyond what the human eye can see). To put this in perspective, the best DSLR camera can achieve around 15 stops of dynamic range. It removes noise and processes the multiple exposures from the camera, creates an ultra-WDR frame and sends it across to a display or a computer vision engine.

To be able to detect a pedestrian in shadow when conditions are bright, the camera needs the necessary dynamic range to detect all elements of the scene it is capturing.

Where the camera is being used as an input to ADAS – for example as part of a pedestrian protection or driver drowsiness detection system – it needs to meet the most stringent reliability and functional safety standards. The Mali-C71 brings low latency and advanced error detection with more than 300 dedicated fault detection circuits to enable system-level certification to the highest standards (ISO26262, ASIL D and IEC 61508, SIL3). We deliver full reference software to control the ISP, sensor, auto white balance and auto exposure, with plans to develop complete automotive software designed for ASIL compliance.

Next generation ISPs need to simultaneously generate data that can be rendered on a display while also processing the data for use by the computer vision engine. These tasks have contrasting requirements, and the Mali-C71 provides one piece of hardware IP capable of providing two differently processed outputs from a single image pipeline.

The Mali-C71 is the first imaging product we’re bringing to market since our acquisition of Apical in 2016. OmniVision Technologies, a leading developer of advanced digital imaging solutions, has welcomed the development:

“OmniVision has been closely collaborating with the ARM ISP team (formerly Apical) for several years now, and see the Mali-C71 as an important advancement in image signal processing for emerging automotive applications. ARM’s expertise in ISP technology together with OmniVision’s best-in-class HDR image sensor technologies offers an industry leading solution for our automotive customers.”

Will Foote, senior partnership manager, OmniVision Technologies

As the automotive industry continues to accelerate towards realising the vision of fully autonomous vehicles, the Mali-C71 will deliver the high quality output for display that is necessary for drivers to quickly make correct choices, and simultaneously provides reliable data for computer vision engines to make safe decisions when the car is in control.

Auto Makers See Opportunity with Embedded Handwriting

Monday, April 10th, 2017

Why handwriting technology in the automotive cockpit will continue to see dramatic growth.

Many people who don’t yet use handwriting technology on phones or tablets as computing input mechanisms may nonetheless already be familiar with digital handwriting technology. There’s a good chance they’ve been introduced to it in what might seem an unlikely place: Their cars.


Figure 1: In the new automotive ecosystem, embedded sensors and display units can communicate with mobile devices inside the car and gather all sorts of external information via the web.

Last year, higher-end auto manufacturers like Audi, Mercedes and Tesla began shipping cars with embedded handwriting technology for controlling GPS systems, entertainment systems and other dashboard controls. Watch a 10-second video showing handwriting at work in an Acura here and learn a bit more about the overall concept here.

But all of this is just the beginning. According to Frost & Sullivan, the market for handwriting recognition (HWR) technology in cars will grow at a rate of more than 30 percent each year through 2020. “The industry is now moving towards controlling the entire infotainment with help from HWR,” the firm adds.

Embedded systems are tough to design: By nature, they’re constrained not only by limited storage space, but also limited memory space and typically, lower performance CPUs compared to computational devices. But even bound by these limitations, today’s digital handwriting technology has delivered remarkable accuracy and consistent benefits to the automotive industry. The most recent technology includes the ability to superimpose characters, cursive words or portions of words on top of each other on the touchpad and still accurately recognize input. A keyboard option incorporating smooth typing enables a true multimodal solution. Here are some reasons why handwriting technology in the automotive cockpit will continue to see dramatic growth:

  • Low driver distraction interfaces have evolved to require handwriting. One reason that handwriting provides a more effective option for controlling GPS or entertainment systems compared to voice are because cars are often noisy, making it difficult to reliably give instructions. Another reason is that voice command systems are very difficult to edit, which makes it more challenging to either revise input or correct recognition errors. Finally, handwriting allows drivers to keep their attention safely focused on the road: Today’s tech is designed for use when the driver isn’t looking at what he’s writing on the touchpad.
  • Multimodal systems are easy for the user to manipulate. Car manufacturers care about customer satisfaction, and drivers today demand a consistent user experience when inputting information—whether they’re doing it by hand, keyboard or voice. Drivers want multiple methods to input that information, depending on what’s most convenient and more importantly, safe. Consistency is key: System responses to keyboard input need to be consistent with responses to handwritten input. No one wants to get a different dictionary response to a query if they’re writing by hand rather than  keyboarding, for instance. A single multimodal system pre-emptively solves that potential problem.
  • Multimodal is great for the integrator. What’s great about multimodal design for systems integrators is that they only need to integrate with a single technology provider that handles multiple forms of input instead of integrating several different functional libraries and debugging any adverse interactions. This shortens the development time required for integration and lessens demands on memory resources and storage. Ultimately, integrating a multimodal interface means developing products that are often lower-cost, quicker time-to-market, and easier to test and validate. A big win all around.

Handwriting also wins points for safety and accuracy. The American Automobile Association (AAA) ranked voice-based command systems, such as the iPhone’s Siri, and found that it significantly distracted car drivers. In a worst-case situation, drivers even at the low speed of 25 mph were distracted for up to 27 seconds, during which they travelled more than three football fields in length.

Handwriting adapts well to multiple situations—e.g., character input when driving, and word input when stopped. Drivers can reach down and direct their cars’ GPS or entertainment systems in dozens of languages (as selected by the OEM), via either cursive or block characters that are easily recognizable, and that can even be written at a tilt—up to over 30 degrees off a level line—and still be recognized. The ability to recognize letters even written at a significant tilt allows for a great deal of human error, which in turn enables increased safety.

Figure 2: Embedded handwriting technology, complemented with voice and other multimodal input options, offers today’s drivers an effective way to enjoy more applications with complex features even as states increase regulation

Figure 2: Embedded handwriting technology, complemented with voice and other multimodal input options, offers today’s drivers an effective way to enjoy more applications with complex features even as states increase regulation.

Handwriting, in sum, is a natural fit for inclusion in the auto market because it offers an intuitive method to control the automotive cockpit, assures minimum driver distraction, and provides a natural input method and low learning curve. Drivers of all ages can use it, and it offers high recognition accuracy of letters, numbers and gestures.

And the handwriting technology in cars can blossom into a full note-taking application for drivers to use when they’re stopped. This is ideal for road warrior executives who must constantly attend meetings, travel and share their notes.

Handwritten input, or ‘digital ink,’ is now as fully capable to be interpreted to text as input from the keyboard and mouse. Furthermore, diagrams such as mind maps, organizational charts, and flow diagrams are capable of being fully converted to digital form in a manner that allows for changes and editing. Today’s technology allows you to create content, edit and format that content, create diagrams, input complex math equations, and easily incorporate the interpreted handwriting results into your digital document workflow.

A booming professional services market has emerged to support developers of embedded handwriting technology, too. Handwriting technology vendors are offering in-depth professional engineering services for use cases based upon the SDK packages offered, all the way to complete turnkey subsystem design services.

Handwriting technology is already embedded in millions of cars today. But the most tremendous growth for this market lies ahead in a wide range of embedded applications and IoT devices. For ISVs and OEMs, the ultimate benefit is a massively improved user experience which enhances customer satisfaction and ultimately sales and profits.

Gary-Headshot_hi_resGary Baum is the Vice President of Marketing at MyScript, the source of the most advanced award winning technology for handwriting recognition and digital ink management. At the Car HMI Concepts and Systems conference, MyScript technology was recognized in the ‘Most Innovative Car HMI Technology’ category.

Renesas Introduces New HEV/EV Inverter Solutions to Shorten Engineering Cycle

Monday, April 10th, 2017

Renesas Electronics Corp., a semiconductor solutions supplier, announced a 100 kW class inverter solution that achieves industry-leading small design class of 3.9 liter (L) for high-power 100 kW class motors in mid- to large-sized hybrid electric vehicles (HEVs) including SUVs, and mid- to small-sized electric vehicles (EVs).

Renesas will provide a solution kit that includes software that maximizes the HEV/EV motor performance and hardware components such as microcontrollers (MCUs), Insulated Gate Bipolar Transistor (IGBT) and fast recovery diode (FRD), and other power semiconductor devices.

The solution enables system developers to reduce development time for various development steps: from specifications analysis to hardware/software development and motor characteristic adjustments. This shortens, for example, the prototyped inverter system development period from two- to three years to just one year, a reduction of over 50 percent, thereby significantly contributing to the reduction of the development cycle and costs.

CO2 emissions are rising due to abnormal weather events caused by global warming and increased levels of environmental pollution. For the automotive industry, this is driving increasing demand for broad adoption of electrically powered systems, such as HEV and EVs, at an earlier stage to reduce these emissions.

In an electrically powered system, the inverter plays a key role converting direct current (DC) power to alternating current and sends out optimum current to the motor whose rotation speed varies according to the driving conditions. Therefore, to realize an inverter system with higher fuel and electric power efficiency, high precision and high efficiency of the motor drive in addition to miniaturization of the inverter is required to allow mounting of the electric unit in the limited space of the engine room for every type and size of vehicle model. Renesas’ new inverter solution addresses these needs.

Renesas has been releasing inverters and solution kits with various capacity designs. In 2014, Renesas developed a solution that realized a size of 2.9 L in the 50 kW class. To respond to the growing needs for large-output motors for use in large vehicles, Renesas has expanded its lineup to support these large-output motors with its new 100 kW class inverter solution included with a motor calibration tool.

Key features of the 100 kW class inverter solution:

(1) Industry-leading small design class of 3.9 L and reduced inverter system weight enable mounting in even smaller spaces
The size and weight of the heat sink included in an inverter can be reduced by employing the temperature management technology that increases the responsiveness and precision of the temperature sensors integrated in the IGBT.

In addition, the included MCU has an integrated enhanced motor control unit (EMU) function that enables motor control to be performed by a dedicated circuit instead of the CPU. This offloads the CPU to take on the CPU processing for the external automotive control unit (known as an electronic control unit, ECU), including the DC/DC converter, second motor, and cooling pump processing. This enables effective automotive ECU integration leading to improved use of the limited space in the engine room.

(2) Shortens development period by more than 50 percent with software that allows quick evaluation in actual cars
In addition to hardware, the inverter solution includes a motor calibration tool that maximizes the motor performance. This simplifies construction of motor control systems that are highly efficient at the system level. This allows system manufacturers to immediately evaluate a prototyped inverter system in an actual car, which can shorten, for example, a three- to two-year prototyped inverter system development period into just one year, a reduction of over 50 percent.

(3) Higher fuel and electric power efficiency with devices optimized for HEV/EV applications
By using IGBT/FRD devices for reduced low conduction loss and low switching loss, the new inverter solution achieves a current loss reduction of approximately 12 percent (Note 1).

By including Renesas main devices that are specialized for HEV and EVs, the new solution reduces the inverter’s power loss by approximately 10 percent (Note 1). This enables increased motor efficiency, which ultimately contributes to increased fuel and electric power efficiency of the inverter system. The new solution is equipped with the RH850/C1H MCU Series, which has an industry-proven resolver-to-digital converter (RDC) function to convert the motor’s rotation angle from analog to digital. The RH850/C1H achieves high-precision motor control of up to 12 to 16 bits. The solution also includes the R2A25110 driver IC with micro-isolator technology (Note 2) enabling high-speed switching.
