Abstract
An electric vehicle includes a pitching state quantity detector for detecting quantity of a pitching-motion of the vehicle, a vehicle weight determiner, a pitching target quantity calculator for calculating a target quantity of a pitching motion at least from the determined vehicle weight, and a torque correction calculator for increasing/reducing a driving torque output, according to a particular differential between the detected pitching-motion state quantity and the calculated target quantity.
Claims12
An electric vehicle with a drive including a motor and a controller, the vehicle comprising:
- pitching state quantity detection means for detecting a pitching-motion state quantity of the vehicle;
- vehicle weight determination means for determining weight of the vehicle;
- pitching target quantity calculation means for calculating a target quantity of a pitching motion of the vehicle at least from the determined vehicle weight;
