摘要： PROBLEM TO BE SOLVED: To surely controllably increase or decrease a wheel cylinder pressure during the initial depressing of anti-skid control irrespective of the deviation of the characteristics of a linear valve.
SOLUTION: The target wheel cylinder pressure Pti of each wheel is calculated according to the brake operation amount of a driver (S20). When the anti-skid control is required, the target wheel cylinder pressure Pti for reducing slip is calculated (S30 to S80). Based on the deviation between the target wheel cylinder pressure Pti and an actual wheel cylinder pressure Pi, a target drive current It for the linear valve is calculated (S100). The target drive current It is changed to a value determined according to the braking conditions of a wheel during the initial depressing of the anti-skid control (S170). Based on a target drive current Ita after the change, the linear valve is controlled (S180).

摘要： PROBLEM TO BE SOLVED: To provide a braking control device of a vehicle preventing a braking force holding control from starting when the holding control is not required.
SOLUTION: A CPU of the control device obtains a brake liquid pressure P1 in stopping a vehicle, when an obtained vehicle speed of the vehicle 10 is reduced to a predetermined speed or lower. Furthermore, the CPU obtains a brake liquid pressure P2 after obtaining the brake liquid pressure P1. When the brake liquid pressure P2 is higher than the value in which an additional predetermined value Pth is added to the brake liquid pressure P1, the braking force holding control for holding the braking force of the vehicle is started. At that time, the CPU obtains the gradient of the vehicle, and when an obtained gradient is not more than a predetermined one, the braking force holding control is not performed. In other words, the braking force holding control can be prevented from starting by mistake when the holding control is not required.

摘要： PROBLEM TO BE SOLVED: To exactly and effectively prevent rapid fluctuation of vehicular deceleration caused by rapid reduction of regenerative braking force in initiation of anti-skid control. SOLUTION: Target braking forces Fbft and Fbrt of front and rear wheels are calculated on the basis of a braking manipulated variable of a driver and a front and rear wheel braking force distribution ratio (S10-50). Target regenerative braking forces Frgft and Frgrt of the front and rear wheels are calculated on the basis of the target braking forces so that regenerative efficiency is maximized (S60). Since there is high probability that the anti-skid control will be initiated when a sudden braking operation or a braking operation during vehicular deceleration is performed by the driver or when a vehicular side-skid speed is high, the target regenerative braking forces are gradually reduced and target friction braking forces are gradually increased (S76A-78 and S88A-92). When the anti-skid control is initiated, the target regenerative braking forces are set at 0 (S82 and 96).
