The invention discloses an electric vehicle ramp torque control method and a vehicle controller. The method comprises the steps that when a vehicle is powered on and can be driven normally without faults, whether the vehicle is in a slope sliding state or not is judged, when it is found that the vehicle is in the slope sliding state, the vehicle enters an anti-slip mode, and required torque is controlled according to anti-slip mode torque; otherwise, the vehicle enters climbing mode judgment, when it is found that the vehicle is in a climbing state, the vehicle enters the climbing mode, and the required torque is controlled according to the climbing mode torque; whether the vehicle is in a downhill mode or not is judged finally, when it is found that the vehicle is in a downhill state, the vehicle enters the downhill mode, required torque is controlled according to the downhill state torque, and when the vehicle is not in the three states, the vehicle enters the normal driving mode. The vehicle torque is controlled based on slope information which is subjected to real-time update, and slope sliding of the electric vehicle during slope driving is avoided; different slope torque control is adopted according to different situations of climbing and downhill, and meanwhile the feeling of a driver is further improved.
