The invention discloses a vehicle fault determination method, a vehicle-mounted system and a vehicle, the method is applied to a steering system of the vehicle, and the steering system of the vehicle comprises a steering angle sensing unit, a camera shooting mechanism and a controller; the method comprises the steps that a turning angle sensing unit is used for collecting turning angle information of a steer-by-wire control assembly and sending the turning angle information to a controller; the camera shooting mechanism is used for collecting steering wheel images of a vehicle and sending the steering wheel images to the controller and used for collecting wheel images of the vehicle and sending the wheel images to the controller. And the controller obtains the turning angle information of the steering wheel according to the steering wheel image, obtains the turning angle information of the wheels according to the wheel image, and judges the fault condition of the vehicle according to the turning angle information of the steer-by-wire control assembly, the turning angle information of the steering wheel and the turning angle information of the wheels. Safety verification of the steering wheel turning angle and the wheel turning angle can be achieved, so that the system function safety level is increased, the system failure risk is reduced, and the reliability of the steer-by-wire system is improved.

    本申请公开了一种车辆故障确定方法、车载系统以及车辆,该方法应用于车辆的转向系统,车辆的转向系统包括转角传感单元、摄像机构、控制器;该方法包括:转角传感单元用于采集线控转向控制组件的转角信息并发送至控制器;摄像机构用于采集车辆的方向盘图像并发送至控制器,以及用于采集车辆的车轮图像并发送至控制器;控制器根据方向盘图像获取方向盘的转角信息,根据车轮图像获取车轮的转角信息,以及根据线控转向控制组件的转角信息、方向盘的转角信息、车轮的转角信息对车辆进行故障情况判定。本申请可实现对方向盘转角及车轮转角的安全校验,从而增加系统功能安全等级并降低系统失效风险,提高线控转向系统的可靠性。
