Abstract:
1. A brake control device for a vehicle comprising: a first wheel brake cylinder equipped to a first vehicle wheel for applying a braking force to the first vehicle wheel; a second wheel brake cylinder equipped to a second vehicle wheel for applying a braking force to the second vehicle wheel; a hydraulic pressure generating device for generating a hydraulic pressure irrespectively of operation of a brake operating member; a hydraulic pressure control valve device disposed between the hydraulic pressure generating device and the first and second wheel brake cylinders for controlling the brake hydraulic pressure in the respective first and second wheel brake cylinders; a hydraulic pressure controlling means for controlling the hydraulic pressure control valve device for one of the first and second wheel brake cylinders equipped to one of the first and second vehicle wheels to be controlled in response to a vehicle driving condition for supplying the hydraulic pressure from the hydraulic pressure generating device to the one wheel brake cylinder for the one vehicle wheel to be controlled at least when the brake operating member is not being operated; a brake amount detecting means for detecting an operational amount of the brake operating member; a vehicle deceleration detecting means for detecting or estimating a vehicle deceleration; a wheel brake cylinder hydraulic pressure detecting means for detecting or estimating the brake hydraulic pressure in the respective first and second wheel brake cylinders; a non-controlled vehicle wheel controlling means for controlling the hydraulic pressure control valve device for the other one of the first and second vehicle wheels which is not controlled by the hydraulic pressure controlling means so as to control the brake hydraulic pressure in the other wheel brake cylinder equipped to the other vehicle wheel which is not controlled by the hydraulic pressure controlling means in response to the operational amount of the brake operating member when the brake operating member is operated while the hydraulic pressure has been supplied to the one wheel brake cylinder by the hydraulic pressure controlling means, the non-controlled vehicle wheel controlling means including:
