Evaluation device of the vehicle of brake operation, evaluation method of brake operation of vehicle, brake control device and the battery control unit

摘要

PPROBLEM TO BE SOLVED: To provide apparatus and method for evaluating vehicle braking operation, a brake control device, and a battery control device, making it possible to determine whether a driver performs an appropriate braking operation, and also emphasize the benefits of fuel-efficient driving. PSOLUTION: A demand braking force is calculated based on the amount of brake pedal depression. At least one of a maximum regenerative braking force outputable by a motor and a maximum regenerative braking force inputable by the battery is calculated. Then, an evaluation value of the braking operation is calculated based on the demand braking force and the maximum regenerative braking force, and information according to the evaluation value is notified. Here, when the demand braking force exceeds the maximum regenerative braking force, the evaluation value of the braking operation is calculated to be lower than when the demand braking force does not exceed the maximum regenerative braking force.
