摘要： PURPOSE:To provide a braking device which promptly determines the braking mode of an auxiliary brake in accordance with the braking operation speed of a main brake and performs correct auxiliary braking from the beginning. CONSTITUTION:A brake pedal operating speed is detected (S4), and if it is within a preset range (S8) shiftdown is usually performed from the fourth gear position to the third gear position (S9), but if it is faster than a preset value (S11) shiftdown is performed at once from the fourth gear position to the second gear position (S13). As an auxiliary braking mode can be determined on the way of braking operation, auxiliary braking delay during sudden braking is avoided to utilize auxiliary braking from the beginning of braking and poor comfortableness is avoided by the shiftdown after operating a main brake.

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 brake system capable of suppressing decrease in braking force during ABS control.
SOLUTION: During an ABS control mode, the brake system corrects the target slip rate in accordance with the turning, and determines whether the vehicle is running on a poor surface road. If the vehicle is running on a poor surface road, the system sets a target slip rate that provides a greater longitudinal force than the aforementioned target slip rate.

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.

摘要： PROBLEM TO BE SOLVED: To exactly detect riding over a stepped part of a front wheel and certainly and effectively execute an appropriate vehicle control based on the result. SOLUTION: In the case where the vehicle is in the braking state (S20), in the case where an increase rate of height of the front wheel is an increase rate reference value or higher (S52); the height of the front wheel is a height reference value or higher (S54); right and left rear wheels are not subjected to an anti-skid control (S56); a speed-reduction degree of the vehicle is a speed- reduction degree reference value or higher (S58); the anti-skid control of the front wheel is started (S60); and a wheel acceleration of the front wheel is not higher than a wheel acceleration reference value or lower, it is judged as a condition that the front wheel rides over the stepped part (S70); a control amount of the anti-skid control is reduced (S300) and a braking force of the front wheel is increased at a predetermined increase slope (S150) when it is judged that the riding over the stepped part of the front wheel is completed (130).

摘要： PROBLEM TO BE SOLVED: To exactly control increase and decrease of wheel cylinder pressure during predetermined braking control irrespective of a characteristic deviation in a linear valve. SOLUTION: A target wheel cylinder pressure Pti of each wheel is calculated in response to a braking manipulate variable of a driver (S20). When anti-skid control is necessary, the target wheel cylinder pressure Pti for reducing slippage is calculated (S30-80). A target driving current It to the linear valve is calculated on the basis of a deviation between the target wheel cylinder pressure Pti and an actual wheel cylinder pressure Pi (S100). The characteristic deviation of the linear valve is compensated (S130). When the anti-skid control is initiated in a condition with compensation of the characteristic deviation not finished, a target driving current Ita for initial decompression is incrementally changed (S160). The linear valve is controlled on the basis of the incrementally changed target driving current Ita (S180).

摘要： PROBLEM TO BE SOLVED: To prevent deceleration of a vehicle positively and effectively from changing suddenly due to a sudden drop in regenerative braking at the start of anti-skid control. SOLUTION: Target braking forces Fbft, Fbrt for front and rear wheels are computed based on the braking movement of a driver and a predetermined front and rear braking force distribution rate (S10-50), and the target regenerative braking forces Frgft, Frgrt for front and rear wheels are computed so that regenerative efficiency may be maximum based on the target braking force (S60). When the target generative braking force is reduced gradually in case that the anti-skid control may be started, and the target regenerative braking force is set to 0 when the anti-skid control is started (S72-98), the regenerative braking is performed so that the target regenerative braking force is at an upper limit, the actual regenerative braking forces Frgfa, Frgra are computed (S210-260), and target friction braking forces for front and rear wheels are controlled so as to be Fbft-Frgfa, Fbrt-Frgra respectively (S110-130).

摘要： PROBLEM TO BE SOLVED: To prevent an assistant brake member from breaking down at running on a bad road or passing through step difference, concerning an assistant brake control device for vehicle generating assistant braking force by contacting an assistant brake member with the road surface. SOLUTION: When emergent brake operation is performed, assistant braking force is generated by contacting an assistant brake member with the road surface. It is discriminated whether emergent brake operation is performed or not, by the operating condition of a brake pedal (step 300). At emergent brake operation, it is discriminated whether it is during running on a bad road or during passing through step difference (step 302). When it is not during running on a bad road and not during passing through step difference, an assistant brake mechanism is operated (step 304). When it is during running on a bad road or during passing through step difference, operation of the assistant brake mechanism is stopped (step 306, 308).

摘要： PROBLEM TO BE SOLVED: To prevent vehicle behavior from being disturbed due to assistant braking force, concerning an assistant brake control device for vehicle generating assistant braking force by contacting assistant brake members with the road surface on a low friction coefficient road. SOLUTION: Assistant brake mechanisms 10FR, 10FL are provided right and left symmetrically against the center line of a vehicle. When a road during running is a fixed low friction coefficient road and the vehicle is required to brake, the assistant brake mechanisms 10FR, 10FL are operated so that cylindrical bodies 12FR, 12FL are grounded. A yaw rate sensor 38 detecting the yaw rate γ of the vehicle is provided. When change Δγ over a fixed value is generated in the yaw rate γ accompanying operation of the assistant brake mechanisms 10FR, 10FL, the assistant brake mechanisms 10FR, 10FL are prohibited to operate.
