A four-wheel independent steering drive-by-wire experiment chassis based on remote driving comprises a chassis frame, a vehicle-mounted control unit, a remote control unit and four steering driving units, steering motors of the steering driving units are connected with the chassis frame through shock-proof connecting rod mechanisms, the bottom ends of the steering motors are connected with speed reducers, the bottom ends of the speed reducers are connected with steering shafts, and the steering shafts are connected with the vehicle-mounted control unit. The bottom end of the steering shaft is connected with a bearing seat, a driving shaft is arranged on the bearing seat in a penetrating mode, and a driving motor and wheels are installed on the driving shaft. During emergency braking, additional friction force is generated in a back wheel reverse deflection mode, so that lateral deflection braking is achieved, the braking distance is shortened, the higher response speed and the safer braking distance are provided, and an ideal scaling experiment platform is provided for follow-up research on multiple steering modes and driving/braking combined control strategies of the intelligent electric vehicle. The method can be used for manipulation stability teaching experiments, and is beneficial to research and development of an electric vehicle four-wheel independent steering system.
