Abstract
The drive wheels of a vehicle are connected to an engine via a torque converter and racing of the drive wheels during starting of the vehicle and subsequent acceleration is prevent by reducing the torque of the drive wheels according to the driving state of the vehicle. A slip factor of the torque converter is computed, and a lower limit of the torque is set based on the slip rate. Insufficient acceleration after starting is avoided by preventing the torque of the drive wheels from falling below this lower limit.
