The invention discloses a vehicle chassis, an electric vehicle and a control method. The vehicle chassis comprises a chassis frame, a steering execution unit, a driving execution unit and a braking execution unit. The chassis frame comprises a rigid frame, and the steering execution unit, the driving execution unit and the braking execution unit are installed on the rigid frame. The steering execution unit comprises a plurality of steering motors corresponding to a plurality of wheels of the electric vehicle, and each steering motor is used for independently controlling the corresponding wheel to steer; the driving execution unit comprises a plurality of wheel-side motors corresponding to a plurality of wheels of the electric vehicle, and each wheel-side motor is used for independently driving the corresponding wheel to rotate; the brake execution unit comprises a plurality of mechanical brake motors corresponding to a plurality of wheels of the electric vehicle, and each mechanical brake motor is used for independently controlling the corresponding wheel to brake. According to the vehicle chassis provided by the invention, the control precision of driving, steering and braking execution units in the chassis can be improved, and the control and running stability of the vehicle is improved.
