Vehicle safety control method, device and system

Abstract

The invention discloses a vehicle safety control method, device and system. The method, the device and the system are used for solving the problem that a vehicle is out of control due to backbone network communication faults. The method comprises the steps that the communication state of a CAN-FD backbone network of a vehicle is monitored, wherein the backbone network is used for transmitting a driving control instruction, and the driving control instruction is used for controlling the motion state of the vehicle; when the communication state of the backbone network is abnormal, motion state information of the vehicle and information of a lane where the vehicle is located is acquired; a target driving control instruction is generated according to the motion state information of the vehicleand the information of the lane where the vehicle is located, wherein the target driving control instruction is used for controlling the vehicle to decelerate to a preset safe vehicle speed in the driving lane; and a target driving control instruction is transmitted through a chassis controller area network (CAN) which is in direct communication connection with the advanced driving assistance system. According to the scheme, after abnormal communication of the backbone network is monitored, vehicle safety control is directly achieved through the CAN, the probability of traffic accidents caused by out-of-control of the vehicle is reduced, and the vehicle control safety is improved.

Description

technical field [0001] The invention relates to the field of vehicle control, in particular to a vehicle safety control method, device and system. Background technique [0002] In the field of vehicle control, self-driving car technology is developing rapidly. Self-driving cars rely on the cooperation of technologies such as artificial intelligence, visual computing, radar, monitoring devices, and global positioning systems, so that vehicle-mounted terminals can automatically and safely operate motor vehicles according to road conditions without any active human operation. [0003] In autonomous vehicle technology, the Advanced Driving Assistance System (Advanced Driving Assistance System, ADAS) can often issue control commands through the backbone network (Controller Area Network With Flexible Data-Rate, CAN-FD) to control the driving direction and speed of the vehicle . [0004] As a network for transmitting control commands, the backbone network CAN-FD plays a vital rol...
