<P>PROBLEM TO BE SOLVED: To achieve deceleration and pedal feel that suppresses the sense of incompatibility at vehicle speed generation from a vehicle stop condition, while securing durability of a pump motor in the vehicle stop condition. <P>SOLUTION: The brake control device of the hybrid vehicle includes: a master cylinder 13; wheel cylinders 4FL, 4FR, 4RL, and 4RR; a VDC brake fluid pressure actuators 2; and an integrated controller 9. The integrated controller 9 has a vehicle stop time electric motor off control part (step S9) and pressure rising gradient restriction parts (step S15-step S20). The vehicle stop time electric motor off control part stops the VDC motor 21 when the vehicle stops by the brake operation, and at vehicle stop time, keeps maintaining the stop condition of the VDC motor 21. When the vehicle stop time electric motor off control ends, the pressure rising gradient restriction part makes the pressure rising gradient of the wheel cylinder pressure low-gradient by control, and at the same time, the pressure rising gradient when there is a generation of the master cylinder pressure before pressure rising is made more gradual than the pressure rising gradient when there is no generation of the master cylinder pressure before pressure rising. <P>COPYRIGHT: (C)2013,JPO&INPIT |
