The invention provides a vehicle lane-changing parking method and system during steering failure, and the method comprises the steps: obtaining the operation information of a steering wheel of a vehicle, and judging whether the steering wheel of the vehicle is in a fault state or not based on the operation information; when a steering wheel of the vehicle is in a fault state, obtaining the remaining steering capability of the vehicle which can be implemented in a drive-by-wire mode, an instruction sent by a driver and environment information within a preset range of the vehicle; determining a parking mode of the vehicle according to the remaining steering capability and an instruction sent by a driver; and generating a parking track based on an automatic driving system and a chassis domain control system of the vehicle, the parking mode, the residual steering capability and the environment information in the preset range of the vehicle, and controlling the vehicle to park based on the parking track. According to the technical scheme provided by the invention, when serious faults such as jamming of the steering wheel occur, lane changing parking is implemented without depending on the turning angle of the steering wheel through cooperation of the automatic driving system and the chassis domain control system, so that the driving safety performance of the vehicle is improved.
本申请提出一种转向失效时车辆换道停车方法及系统,所述方法包括:获取车辆方向盘的运行信息,并基于所述运行信息判断所述车辆的方向盘是否处于故障状态;当所述车辆的方向盘处于故障状态时,获取所述车辆可通过线控方式实施的剩余转向能力、驾驶员发送的指令和所述车辆预设范围内的环境信息;根据剩余转向能力和驾驶员发送的指令确定所述车辆的停车方式;基于车辆的自动驾驶系统和底盘域控系统及停车方式、剩余转向能力和车辆预设范围内的环境信息生成停车轨迹,并基于停车轨迹控制车辆停车。本申请提出的技术方案,当发生方向盘卡死等严重故障时,通过自动驾驶系统和底盘域控系统协同,不依方向盘转角实施换道停车,提高了车辆的行车安全性能。
