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.
本发明公开了一种车辆安全控制方法、装置和系统,用以解决由于主干网通信故障而导致车辆失控的问题。本方案包括:监测车辆的CAN‑FD主干网的通讯状态,主干网用于传输行驶控制指令,行驶控制指令用于控制车辆的运动状态;当主干网的通讯状态异常时,获取车辆的运动状态信息和车辆所在车道的信息;根据车辆的运动状态信息和车辆所在车道的信息生成目标行驶控制指令,目标行驶控制指令用于控制车辆在所行驶的车道内减速至预设安全车速;通过与所述高级驾驶辅助系统直接通信连接的底盘控制器局域网络CAN传输目标行驶控制指令。本方案在监测到主干网通信异常后直接通过CAN实现车辆安全控制,降低车辆失控而引发交通事故的概率,提高车辆控制安全性。
