The technical scheme of the invention is as follows:
an AEB and LKA fusion control system for a passenger car comprises an AEB system and an LKA system, wherein the AEB system comprises an AEB controller and a fusion system connected with the AEB controller, the fusion system comprises a radar, a camera and a fusion module, and the fusion module realizes signal fusion of the radar and the camera by an ECU (electronic control unit) of the radar; the LKA system comprises an LKA system controller integrated in the radar ECU and a camera shared by the LKA system and the AEB system.
Preferably, the camera is used for target detection, and the radar realizes target detection and fusion algorithm and function realization.
Preferably, the lane line detected by the camera is used for realizing an LKA function, the system sends an LKA steering request to a whole vehicle CAN network, and an EHPS system of the whole vehicle reads the steering request from the CAN and sends the steering request to the actuator.
Preferably, the pedestrian and vehicle targets detected by the camera and the radar simultaneously are generated in an ECU of the radar as fusion targets, and the fusion targets are sent to an AEB controller for realizing an AEB function.
The invention has the advantages that:
1. according to the AEB and LKA fusion control system, the pedestrian monitoring of the AEB system is more accurate, and the AEB system is complementary to a radar, so that the safety of the AEB system is improved, traffic accidents are reduced, and fault rates of AEB false alarm and the like are reduced; the AEB system has the advantages of more accurate target positioning, more accurate target speed detection, better target type judgment, improved object recognition probability, lower false triggering rate and more accurate angle calculation.
2. According to the invention, the LKA and the AEB system share one camera, and the LKA controller is integrated in the radar, so that one camera and one LKA controller hardware are reduced, and the cost of the whole vehicle is reduced.
