摘要：Systems and methods for detecting wheel-spinning situations of a vehicle. Onesystem includes a controller. The controller is configured to determine a speed of eachwheel of the vehicle based on information received from a plurality of wheel speed
sensors, to identify a second slowest wheel of the vehicle based on the speed of eachwheel, to calculate a vehicle acceleration torque based on an acceleration of the secondslowest wheel of the vehicle and a mass of the vehicle, to calculate a torque ratio basedon the vehicle acceleration torque and a wheel drive torque, and to activate a tractioncontrol system when the torque ratio is greater than a predetermined threshold.
