ADAS DEVELOPMENT
OEM guide to ADAS development As automotive electronics becomes more complex, the quest is on for economical ways to cover the widest possible range of requirements. ERIC PINTON | RENESAS ELECTRONICS
In recent years, few topics have stoked the automotive industry’s collective enthusiasm like autonomous vehicles. Pushed by widely publicized breakthroughs in connected vehicle development, deep learning software, and data-driven analytics by new players such as Google, Tesla, and Uber, auto manufacturers and OEMs have raced to deliver fully autonomous vehicles. Reality, however, has differed from these ambitions. Many projects have been beset by major delays and foundational challenges. The challenges include the complex architecture demanded by the massive number of heterogeneous sensors in a fully distributed system; the validation of nearly
infinite driving use cases; and hardware and software providers having dramatically different business models. Though autonomous vehicles make business sense to mobility service providers, there are few concrete business cases to justify the investment so far. Additionally, factors such as vehicle electrification and NCAP (New Car Assessment Program, which evaluates new automobile designs for performance against various safety threats) have squelched the hype around autonomous vehicles. Thus OEMs are looking for a more realistic foundation for building sustainable businesses. Safety, driven by the next version of NCAP requirements and legislation, remains the primary market driver for ADAS. There are five autonomous functions covered by the NCAP 2020 Assessment – automatic emergency braking, traffic sign recognition, lane-keep assist, vehicle detection, and pedestrian detection. These have became
mainstream for vehicles in 2019/2020. The NCAP assessment is still evolving. Over time, the number of functions it covers has increased. For example, an earlier version of NCAP focused only on front driving. But NCAP 2025 requires 360° surround view, far-distance view, steering, and interior monitoring. Moreover, legislation worldwide is encouraging the use of the cameras for safety purposes. U.S. cars now must have backup cameras. Automatic emergency braking will be mandated in Europe by February 2022, and China has issued new safety legislation for commercial vehicles. Besides safety, the convenience enabled by certain ADAS (Advanced Driver Assistance Systems) functions--such as automatic parking and adaptive cruise control with steer assist-are likely to boost demand for advanced
