Abstract: The brake system of the invention, during the ABS control mode, corrects the target slip rate in accordance with the turning of the vehicle, 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.

Abstract: In a vehicle brake control device, it is determined whether a first starting condition, that a master cylinder pressure and a rate of change of the master cylinder pressure are equal to or more than respective first reference values, is satisfied. Furthermore, it is determined whether a second starting condition is satisfied based on a determination as to whether the master cylinder pressure is equal to or more than a second reference value at a time when a predetermined time has elapsed since a time when the first starting condition was satisfied . In a case where the second starting condition is determined as being satisfied, a brake assist control is executed until a termination condition of the brake assist control is satisfied.

Abstract: A target wheel cylinder pressure for each wheel is calculated according to an amount of braking operation performed by a vehicle operator. When anti-skid control is required, the wheel cylinder pressure is controlled to be equal to the target wheel cylinder pressure for reducing the brake slip of the wheel. When one of the rear-left and the rear-right wheels is anti-skid controlled, the target wheel cylinder pressure for the other wheel for which the anti-skid control is not performed is set to the same value as the target wheel cylinder pressure for the wheel for which the anti-skid control is performed. Linear valves are controlled based on the target wheel cylinder pressure, controlling the wheel cylinder pressures for the rear-left and the rear-right wheels to have substantially the same value.

Abstract: Each of target braking forces for front and rear wheels of a vehicle is calculated based on an amount of braking performed by a driver and a predetermined braking force distribution ratio between the front wheels and the rear wheels. Each of the target regenerative braking forces for the front and rear wheels, respectively, is calculated based on a corresponding one of the target braking forces such that a maximum regeneration efficiency is obtained. If the driver has performed an abrupt braking operation, if the driver has performed a braking operation when the vehicle runs at a high deceleration, or if the vehicle runs at a high lateral speed, it is quite likely that anti-skid control will be started afterwards. Therefore, the target regenerative braking forces are gradually reduced, and target frictional braking forces are gradually increased. If anti-skid control is started, the target regenerative braking forces are set as 0.

Abstract: A braking and driving force control apparatus and method are for a vehicle having a frictional braking device for applying a braking force individually to each wheel and a regenerative braking device for generating a common braking force to a plurality of wheels. A target braking force is calculated on the basis of a driver's braking operation or traction control. The regenerative braking device is controlled so as to achieve the smallest target braking force of the target braking forces of the plurality of wheels. The frictional braking device is controlled so as to achieve the target braking force of another wheel, different from the wheel having the smallest target braking force, in cooperation with the regenerative braking device. Thus, the efficiency of regenerating energy is enhanced.

Abstract: In a brake control system for a vehicle, a target wheel cylinder pressure of each wheel is calculated in accordance with a braking force applied by the driver, a brake control mode is determined to be one of an increase pressure mode, a decrease pressure mode, or a maintain pressure mode, and a target increase/decrease force slope is calculated in accordance with a slip amount of the wheel. In particular, the target wheel cylinder pressure is calculated based on actual wheel cylinder pressure and the target increase/decrease pressure slope when starting anti-skid control, the target wheel cylinder pressure is calculated after starting the anti-skid control based on the most recent target wheel cylinder pressure and the target increase/decrease pressure slope, and the wheel cylinder pressure Pi is controlled so as to become equal to the target wheel cylinder pressure.
