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).

摘要： PROBLEM TO BE SOLVED: To overcome the problem of not being able to provide sufficient effect of anti-skid control when an accumulator pressure is used during control of an electric command brake ECB, a master cylinder pressure is fed to a wheel cylinder during initialization, the anti-skid control is executed by switching to the accumulator pressure when execution conditions for the anti-skid control are satisfied during an initializing process, and the accumulator pressure is low. SOLUTION: When the execution conditions for the anti-skid control are satisfied in a state of feeding the fluid pressure of a master cylinder 12 to the wheel cylinder 90 and the fluid pressure of an accumulator 44 is insufficient from a perspective of a braking demand of a driver, the anti-skid control using the fluid pressure of the accumulator 44 as a pressure source is prohibited.

摘要： PROBLEM TO BE SOLVED: To accurately and properly control a wheel cylinder pressure at a target pressure by a linear value. SOLUTION: A target wheel cylinder pressure Pti of each wheel is calculated in response to a braking manipulated variable of a driver (S20). During anti-skid control, a braking control mode is determined as one selected from among a compression mode, a decompression mode and a holding mode (S40, 60 and 70), and a target compression/decompression gradient ΔPti is calculated in response to a slip amount of a wheel (S80). Particularly at initiation of the anti-skid control, the target wheel cylinder pressure Pti is calculated on the basis of an actual wheel cylinder pressure Pi and the target compression/ decompression gradient ΔPti, and after initiation of the anti-skid control, the target wheel cylinder pressure Pti is calculated on the basis of a previous target wheel cylinder pressure Ptfi and the target compression/decompression gradient ΔPti (S90-120). The wheel cylinder pressure Pi is controlled so it becomes the target wheel cylinder pressure Pti (S400).

摘要： PROBLEM TO BE SOLVED: To exactly set braking pressures and their changes of a pair of wheels to conform to each other and improve vehicular braking performance in comparison with the case when target compression/decompression gradients are set to conform to each other. SOLUTION: A target wheel cylinder pressure Pti of each wheel is calculated in response to a braking manipulated variable of a driver (S20-70). When anti- skid control is necessary, a wheel cylinder pressure is controlled at a target wheel cylinder pressure for reducing braking slips of a wheel (S80-110). When only one of right and left wheels is under the anti-skid control, a target wheel cylinder pressure of a wheel in the opposite right or left side not under the anti-skid control is set at the same value as a target wheel cylinder pressure of a wheel under the anti-skid control, a linear valve is controlled on the basis of the target wheel cylinder pressure, and by this, wheel cylinder pressures of the right and left wheels are controlled at substantially the same pressure (S130-170).

摘要： PROBLEM TO BE SOLVED: To minimize deterioration of vehicular braking control performance when an anomaly occurs in a pressure sensor detecting a wheel cylinder pressure. SOLUTION: A target wheel cylinder pressure Pti is calculated in response to a braking manipulated variable of a driver (S20). When anti-skid control is necessary, the target wheel cylinder pressure Pti for reducing slips is calculated (S40 and 50). A target driving current It to a linear valve is calculated on the basis of a deviation between the target wheel cylinder pressure Pti and an actual wheel cylinder pressure Pi (S70). When the pressure sensor is normal, the linear valve is control on the basis of the target driving current It (S30 and 80). If there is an anomaly in the pressure sensor, the linear valve is intermittently opened and closed so that the wheel cylinder pressure Pi becomes the target wheel cylinder pressure Pti (S30 and 90-150).

摘要： PROBLEM TO BE SOLVED: To determine a crossover road during anti-skid control more accurately. SOLUTION: During the anti-skid control, a target compression/decompression gradient ΔPti is calculated in response to a braking control mode, vehicular deceleration Gxb and a slip amount of a wheel (S40-80). In the anti-skid control, when the time after the initiation of the anti-skid control passes exceeding a predetermined time Tc with respect to to one of right and left wheels (S220-240), it is determined that there is a crossover road and the vehicular deceleration is corrected by a predetermined value α0 (S290). When the number of times of decompression initiations of the anti-skid control becomes the predetermined number of times or more (S250), a crossover road is determined in response to a difference between right and left wheels that is an average value of wheel cylinder pressure in the decompression initiations (S260 and 270). If there is a crossover road, the vehicular deceleration is corrected in response to a deviation of the average value of the wheel cylinder pressure (S280 and 300).

摘要： PROBLEM TO BE SOLVED: To provide an anti-skid device capable of decelerating reflecting a driver's intention and shortening a braking distance by suppressing rapid reduction of wheel speed caused by unnecessarily high braking pressure intensification. SOLUTION: A control function is provided by setting a control target value of a wheel cylinder pressure in response to a brake manipulated variable of a driver. A pressure intensifying gradient in a re-intensifying mode during anti- skid control and an intensification time variation characteristic such as duration are changed in response to a deviation between the target value and a detected cylinder pressure.

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 control device for a vehicle as improvement of a conventional technique in which transmission of an excessive load to the power source side can be precluded by disengaging a clutch to connect and disconnect the power transmission path in case the fluctuation of the brake torque is large, for example during ABS control, but this leads to a drop of the accelerating performance of the vehicle. SOLUTION: In case the brake torque to a driving wheel 52 fluctuates much, the degree of transmission of the power is reduced by sinking the engaging torques of a first clutch C1 and a second clutch C2 so as to prevent an excessive load from being transmitted to an engine 14 and a motor generator 16. If at this time the request for acceleration is large, only the second clutch C2 is disengaged, while the first clutch C1 remains in engagement, and thereby the accelerating performance is well secured while the total degree of transmission of the two clutches C1 and C2 is reduced.
