<p>Changes in the number of passengers or in load cause significant changes in vehicle weight, thus making it impossible to appropriately suppress a pitching motion of a vehicle chassis, hence rendering a necessary driving torque difficult to ensure, resulting in a decrease in drivability being insuppressible. An electric vehicle with a drive including a motor and a controller comprises a pitching quantity detector that detects a magnitude of a pitching motion of the vehicle, a vehicle weight determination unit that determines weight of the vehicle, a torque correction calculator that uses a traveling state of the vehicle and the determined vehicle weight to change a driving torque output from the drive, and a control gain varying element that adjusts a control gain of the torque correction calculator according to a magnitude of the vehicle weight value output from the vehicle weight determination unit.</p> |
