Title:
CONTROL DEVICE FOR ELECTRIC VEHICLE, SYSTEM FOR CONTROLLING ELECTRIC VEHICLE, AND METHOD FOR CONTROLLING ELECTRIC VEHICLE
Document Type and Number:
WIPO Patent Application WO/2018/221269
Kind Code:
A1
Abstract:
Provided is a control device for an electric vehicle, the device being capable of suppressing vehicle destabilization caused by the rear wheels locking first or suppressing a deterioration in driving performance caused by the front wheels locking too soon. The control device comprises: a regenerative braking force calculating unit that calculates regenerative braking force generated by a front motor and a rear motor on the basis of demanded braking force demanded by the electric vehicle; a power limiting unit that reduces the regenerative braking force on the basis of the power limit of a power source; and a friction braking force outputting unit that outputs, to a brake device, a command to generate friction braking force in accordance with a regenerative braking force reduction amount, which is the amount by which the regenerative braking force is reduced by the power limiting unit.
