Patent ID: 8862300

Claim:
A pitch control device for an electric vehicle, configured to conduct control for suppressing a change in an attitude of the electric vehicle due to a pitch motion thereof while the electric vehicle is accelerating/decelerating by a driving motor, the pitch control device comprising: a drive unit that calculates a braking/driving torque based upon a request for an acceleration/deceleration of the electric vehicle and outputs the calculated braking/driving torque as a braking/driving torque command value to the driving motor; and a torque correction value calculator that calculates a torque correction value for the braking/driving torque so that the braking/driving torque command value will be a traveling resistance equivalent torque that is a value obtained when a force needed to stop the electric vehicle on a sloped road surface and maintain the electric vehicle in a stopped condition is converted into a torque of the driving motor; wherein the drive unit corrects the braking/driving torque in accordance with the torque correction value calculated in the torque correction value calculator, and outputs the corrected torque as the braking/driving torque command value to the driving motor; wherein assuming that the braking/driving torque is corrected and that the corrected braking/driving torque is output as the braking/driving torque command value to the driving motor, the pitch control device calculates a time-integrated value of a negative acceleration of the electric vehicle, then when the time-integrated value of the negative acceleration agrees with a speed of the electric vehicle, the pitch control device enables the correction of the braking/driving torque, and outputs a corrected value thereof as the braking/driving torque command value to the driving motor.
