Abstract:
1. An electric vehicle with a drive including a motor and a controller, the vehicle comprising: pitching state detection means for detecting a state of a pitching motion of the vehicle; vehicle weight determination means for determining weight of the vehicle; pitching target quantity calculation means for predicting a pitching-motion state quantity of the vehicle from a traveling state thereof and from the determined vehicle weight; a torque correction calculator for increasing/reducing a driving torque output from the drive; and control gain varying means for changing an internal control gain of the torque correction calculator as appropriate; wherein: the torque correction calculator increases/reduces the driving torque of the drive according to a particular differential between the pitching-motion state quantity that the pitching state detection means has detected, and a target quantity that the pitching target quantity calculation means has calculated; and the control gain varying means adjusts the control gain of the torque correction calculator according to a particular output value of the vehicle weight from the vehicle weight determination means.
