Abstract
A vehicle control device, a vehicle control method, and a vehicle control system according to the present invention estimate, in response to a deceleration command to a vehicle, the first deceleration generated by a frictional braking force based on characteristics of deceleration with respect to a force acting on a friction pad of a frictional braking device, determine the second deceleration by subtracting the first deceleration from the deceleration command, output the first command for generating the frictional braking force based on the deceleration command, and output the second command for generating the regenerative braking force based on the second deceleration. This allows compensating for uncertainty in achieving deceleration by frictional braking, and improving the accuracy of the actual deceleration with respect to the deceleration command.
