A brake apparatus for a vehicle generally sets an upper limit value of regenerative braking force to the maximum value of the regenerative braking force which can be generated at the present. In the case of a front-wheel-drive vehicle, the total braking force, the sum of front-wheel braking force (front-wheel hydraulic braking force+regenerative braking force) and rear-wheel braking force (rear-wheel hydraulic braking force), is rendered coincident with a target braking force corresponding to a brake pedal depressing force, and the regenerative braking force is set to a largest possible value equal to or less than the upper limit value. As a result, the regenerative braking force can be larger than front-wheel-side target distribution braking force. The upper limit value is decreased from the maximum value by an amount corresponding to the degree of easiness of occurrence of a locking tendency at the driven wheels (front wheels).

The invention relates to a control method for eliminating jitter of a pure electric vehicle. A vehicle control unit analyzes the real driving intention of a driver by acquiring accelerator pedal signals, gear signals and brake pedal signals, and thus calculates driver required torque TqDrvReq; a motor controller feeds back a motor actual revolving speed signal MotSpd of the vehicle control unit, and the vehicle control unit filters the MotSpd to obtain MotSpdFil. Through the difference between the MotSpdFil and the MotSpd, corrected torque TqCorr is calculated by adopting a PID (Proportion Integration Differentiation) algorithm to correct the driver required torque.
