The invention relates to a redundancy warning system and method for an automatic driving vehicle. The system is suitable for an L3-level automatic driving vehicle. The system comprises a vehicle body controller L, a vehicle body controller R and an automatic driving controller. The automatic driving controller is connected with the vehicle body controller R through a CAN (Controller Area Network) line and is also connected with the vehicle body controller L through a redundant CAN line; the vehicle body controller L and the vehicle body controller R are connected through a CAN line; the vehicle body controller L controls the steering lamp through a hard wire, and the vehicle body controller R controls the brake lamp through a hard wire. The brake lamp and the steering lamp are connected to different controllers respectively, and the problem that when a single controller or a single link fails (including single-point failure and multi-point failure) in a traditional framework, the brake lamp or the steering lamp (double flash) cannot be lightened to warn a rear vehicle is solved.
本发明涉及一种自动驾驶车辆的冗余警示系统及方法,本系统适用于L3级自动驾驶车辆;系统包括车身控制器L、车身控制器R以及自动驾驶控制器;所述自动驾驶控制器通过CAN线与所述车身控制器R相连,还通过冗余CAN线与车身控制器L相连;车身控制器L与车身控制器R之间通过CAN线相连;车身控制器L通过硬线对转向灯进行控制,车身控制器R通过硬线对制动灯进行控制。本发明通过将制动灯和转向灯分别接在不同的控制器,解决了传统架构中单一控制器或单一链路失效时(包括单点失效和多点失效)无法点亮制动灯或转向灯(双闪)向后方车辆进行警示的问题。
