The AC100 radar on this platform enables several safety and driver comfort functions including distance and collision warning and integration with braking systems to provide follow-to-stop adaptive cruise control (ACC). The technology can also enable further features such as activation of reversible restraint systems, pre-crash pre-fill of brakes, adaptive brake assist and automatic emergency braking (AEB).
The launch of the AC100 on the PSA EMP2 platform, says TRW, represents an important milestone on TRW's roadmap for Driver Assistance Systems, with this particular module launching in C and D segments. The company recently announced intentions to target more affordable market segments, effectively "democratising" the market for safety-relevant DAS. In this context, Peter Austen, director of TRW's Driver Assistance Systems (DAS) explained that the fitment growth of such technologies will be exponential in coming years as governments worldwide strive to significantly reduce road fatalities. "New legislation, changes to New Car Assessment Program (NCAP) ratings schemes and insurance incentives are coming into effect and the industry needs to be ready with the right solutions. Our AC100 and next generation radar have been specifically developed to help enhance road safety and address these market trends,” Austen said.
The AC100 system offers much of the functionality of TRW’s previous generation 77GHz AC20 radar, but at a significantly lower cost - achieved primarily through lower frequency operation and optimised performance for mainstream vehicles. It can detect vehicles up to a range of approximately 150m and is suitable for a full range of driving conditions including high speed motorway driving. Radar technology can operate in poor weather conditions including fog and heavy rain, unlike laser based systems that rely on a clear optical path.
