Provided is a braking torque controller which is capable of alleviating a lack of deceleration caused by a delayed generation of actual hydraulic pressure braking torque in a hydraulic pressure brake system. A brake control unit (10) comprises a basic target regenerative braking torque calculation part (S2 in Fig. 2) which calculates a basic target regenerative braking torque corresponding to a driver-requested total braking torque; a final target regenerative braking torque calculation part (S3 in Fig. 2) which calculates a final target regenerative braking torque giving a delay in a liquid pressure brake system (A); a running regenerative braking torque calculation part (S4 in Fig. 2) which calculates a running regenerative braking torque from the final target regenerative braking torque; a basic target hydraulic pressure braking torque calculation part (S6 in Fig. 2) which calculates a basic target hydraulic pressure braking torque by subtracting the running regenerative braking torque from the driver-requested total braking torque; and a final target liquid pressure braking torque calculation part (S7 in Fig. 2) which calculates a final target hydraulic pressure braking torque by adding a difference that is calculated by subtracting the basic target regenerative braking torque from the final target regenerative braking torque to the basic target hydraulic pressure braking torque. |
