摘要： The present invention provides a vehicle control apparatus capable of ensuring drivability when a vehicle is turning.
The vehicle control apparatus calculates a vehicle body speed based on a wheel speed of each of wheels, and controls a slip state of each of the wheels according to states of a corrected wheel speed, which is acquired by correcting the wheel speed based on vehicle specifications indicating a position of each of the wheels, and based on the vehicle body speed. Alternatively, the vehicle control apparatus calculates a corrected wheel speed, which is acquired by removing a wheel speed change component generated along with a turn from a wheel speed of each of a plurality of wheels, and controls a slip state of the wheels according to states of the control wheel speed and the vehicle body speed.

摘要： 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.

摘要： An object of the present invention is to provide a vehicle control apparatus capable of stabilizing a behavior of a vehicle when a regenerative braking force is generated. To achieve this object, a vehicle control apparatus according to one aspect of the present invention includes an electric motor configured to provide a regenerative braking force to left and right drive wheels that are one of front wheels and rear wheels, a friction braking device configured to provide a friction braking force to left and right trailer wheels that are the other of the front wheels and the rear wheels, and a behavior estimation unit configured to estimate a behavior of a vehicle. The vehicle control apparatus reduces the regenerative braking force and increases the friction braking force provided by the friction braking device, if the behavior estimation unit estimates a preset behavior when the regenerative braking force is generated.
