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.
