AUTOMOTIVE FEATURE


scalability demand. However, this approach leads to new challenges. From a HW perspective, the challenge


is to find semiconductor vendors able to offer an open platform that scales the device from entry to high, while maintaining an upgrade compatibility. Silicon shall provide a high level of performance, which consumer products from mobile, PC or gaming can offer. But power consumption and functional safety are also a must, which devices from the consumer arena were not initially designed for. From a SW perspective, the OEMs will

autonomous driving and the call for new innovation

looking for development efficiency and a scalable platform able to cover the wide range of requirements from the basic NCAP function up to affordable L2 + (L3 for premium). The hype of full autonomous driving


has been slowing down and now OEMs are looking for a more realistic scenario for a sustainable business. The goal was to be the first to deliver


an autonomous vehicle, but reality has been very different. Many items have led to major delays and expenses above the initial estimation, to name a few: The complexity of the architecture due to a massive number of heterogeneous sensors in a fully distributed system; the validation of such a system with almost infinite use cases and the business model


among the different HW and SW providers. But trends, such as electrification of the vehicle or safety


requirements, which are pushed by the need to protect the climate, NCAP assessment and legislation, required the market to reconsider their overall investment priorities and ultimately reduced the investment in autonomous vehicles. This shifted the introduction of automated cars. Safety requirements, driven by the next version of NCAP


requirements and legislation, i.e. backup cameras or AEB, remain the main market driver for ADAS. In addition, the convenience functions of ADAS will drive demand as they become more affordable. At the same time, a few convenience functions such as


automatic parking and adaptive cruise control with steer assist (level 2/Level 2+) becomes popular at the end user. Customers see a concrete benefit versus the slight cost of the optional vehicle upgrade. In the end, OEMs are forced to adapt their vehicles to the


latest NCAP requirements or legislation while providing ADAS as a convenience function when there is a clear expectation from the market.


FEATURES UP, COMPLEXITY UP – OEMS NEED SCALING PLATFORMS! As complexity is growing, OEMs are looking for development efficiency and a scalable platform able to cover the wide range of requirements from the basic NCAP function up to affordable L2 + (L3 for premium). The trend of integration of several functions into a centralised ECU looks quite appealing to target this

look for the best SW supplier for a specific function either from a traditional Tier 1 or even a new SW provider, which requires an open SW model. Artificial intelligence is the next


challenge, which is completely a new class of algorithms, which was still in research a few years ago, and now is expected to actively drive our cars. These markets require dependable SW


and functional safety, which are strong assets for Renesas. The Renesas R-Car platform for Automotive offers initially a high computing platform for applications like In-Vehicle- Entertainment or Infotainment, this platform is now being extended to devices used in ADAS and Vehicle Servers. R-Car V3M and V3H are the two first


products from this platform and are now in full mass production and deployed all over the globe for front camera, surround view and in Lidar applications. R-Car V3M is the entry device, covering NCAP2020-entry and legislation requirements. It also provides a very cost-effective solution for 3D Surround view systems. R-Car V3H is more tailored for Smart Camera premium features, this device is also very suitable for convenience functions such as Automatic parking and is used in LIDAR systems. Both R-Car devices can accommodate embedded conventional computer vision algorithms and AI for embedded. Renesas continues to work to address


the new requirements for the market, including features that support NCAP2025 and autonomous functions for Level 2+ / Level 3. The insight into the automotive market and tight collaboration with Tier1’s and OEMs will allow Renesas to design semiconductor solutions that drive mobility towards new experiences for the driver and increased safety.
