Embodiment Construction

[0016] like figure 1 As shown, the AEB and LKA fusion control system for passenger cars proposed by the present invention includes an AEB system and an LKA system, the AEB system includes an AEB controller and its connected fusion system, and the fusion system includes a radar, a camera and a fusion system. The fusion module realizes the signal fusion of the radar and the camera by the ECU of the radar; based on the fusion of the radar and the camera of the AEB system, the LKA system includes the LKA system controller integrated in the radar ECU, and is shared with the AEB system. of a camera.

[0017] The camera is used for target detection, and the radar realizes target detection, fusion algorithm and function realization.

[0018] The lane line detected by the camera is used to implement the LKA function, the system sends the LKA steering request to the vehicle CAN network, and the vehicle's EHPS (Electronic Hydraulic Power Steering System) reads the steering request from ...

Abstract

The invention discloses an AEB and LKA fusion control system for a passenger car, the AEB and LKA fusion control system comprises an AEB system and an LKA system, 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 through an ECU of the radar; the LKA system comprises an LKA system controller integrated in the radar ECU and a camera shared by the AEB system. According to the AEB system, pedestrian monitoring is more accurate, complementation with radar is formed, the safety of the AEB system is improved, traffic accidents are reduced, and the failure rate of AEB misinformation and the like is reduced; the LKA system 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.

Description

technical field [0001] The invention relates to the field of automatic driving, in particular to an AEB and LKA fusion control system for passenger cars. Background technique [0002] In accordance with the provisions of JT / T1242-2019 "Performance Requirements and Test Procedures for Automatic Emergency Braking System of Commercial Vehicles" issued by the Ministry of Communications, it is necessary to add pedestrian monitoring function to the performance of AEB (Automatic Braking System) of commercial vehicles. In accordance with the implementation requirements of the national standard GB7258 "Technical Conditions for Motor Vehicle Operation Safety", from February 1, 2022, highways and tourist buses over 11 meters long need to install the LKA (lane keeping assist) function. [0003] At present, the vehicle monitoring and pedestrian monitoring of the AEB system in the passenger car industry are independent systems, and the vehicle monitoring uses a single radar; the pedestria...
