摘要： A vehicle motion control device reduces noise resulting from operation of a vacuum booster when an automatic pressure control is performed by properly controlling the energization of a linear solenoid of a booster actuator. An automatic hydraulic pressure generator is controlled in accordance with the vehicle motion condition and a hydraulic pressure control valve device is controlled to perform the automatic pressure control. A target electric current of the linear solenoid for actuating the vacuum booster is instantaneously increased to a starting target value which corresponds to an electric current value immediately before starting the operation of the vacuum booster and which is less than a maximum value of the target electric current, and then is gradually increased approximately to the maximum value of the target electric current.

摘要： A brake control device for a vehicle controls a vehicle wheel by supplying a hydraulic pressure generated by a hydraulic pressure generating device to a wheel brake cylinder of the vehicle wheel when a brake operating member is not being operated. When the brake operating member is operated while the hydraulic pressure has been supplied to the wheel brake cylinder for the vehicle wheel, a hydraulic pressure control valve device for the other vehicle wheel is controlled for supplying the hydraulic pressure to a wheel brake cylinder for the other vehicle wheel. Therefore, the hydraulic pressure is supplied to the wheel brake cylinder for the other vehicle wheel as well.

摘要： A device for controlling a braking force of the vehicle has a braking force boosting control portion that increases the braking force in response to a detection of a possibility of a collision with an obstacle in the driving course of the vehicle, and a boost-reducing control portion that controls the boosting control portion so as to reduce the braking force when a steering operation is executed by a driver of the vehicle as compared to a braking force to be generated when no steering operation is executed. The braking forces on individual wheels are reduced depending upon the lateral force on the corresponding wheel. In the device, the precrash safety braking operation does not interfere with the steering operation of the driver so that the steering controllability may be ensured while the vehicle is slowed down.

摘要： In a brake control apparatus (20) that controls braking forces which are applied to wheels based on the pressure of a brake fluid, when a hydraulic pressure actuator (40) controls the hydraulic pressure that is transferred to wheel cylinders (23) using the hydraulic pressure of the brake fluid in a power hydraulic pressure source (30), a brake ECU (70) closes a simulator cut valve (68) if the pressure of the brake fluid in the power hydraulic pressure source (30) falls below a predetermined value (Pssc) or if it is determined that the number of times the brake operation member (24) is operated within a predetermined value. In addition, the ECU (70) may change the timing for closing the simulator cut valve (68) based on the road surface condition estimated at the time of antilock control start. Thus, a driver is less likely to feel unusual brake feel when a braking control mode is changed.

摘要： An electronic control unit inputs from temperature sensors a temperature of the heating side of a thermoelectric conversion section assembled to each of brake units provided for left and right rear wheels. When the temperature of the heating side is equal to or lower than a predetermined temperature, the electronic control unit drives and controls a brake hydraulic pressure control section so as to operate the brake units preferentially over brake units provided for left and right front wheels. With this operation, each of the brake units generates friction heat, and heats the heating side of the corresponding thermoelectric conversion section, whereby the thermoelectric conversion section efficiently collects thermal energy and generates electrical power. Meanwhile, when the heating side temperature is higher than the predetermined temperature, the electronic control unit drives and controls the brake hydraulic pressure control section so as to decrease the proportion of the braking forces applied by the brake units and increase the proportion of the braking forces applied by the brake units.

摘要： A target yaw moment Mt of a vehicle is calculated to make the vehicle run stably (S20). The change rate φd of an accelerator pedal operation amount φ is calculated (S30). Based on the change rate φd, a proportion ωs1 for a steering angle control is calculated (S50). When the change rate φd is a positive value, the proportion ωs1 gradually increases as the change rate φd increases. A proportion ωb for a braking force control is calculated by subtracting the proportion ωs1 from 1 (1−ωs1) (S60). Based on the proportions ωs1 and ωb, a target yaw moment Mts for the steering angle control and a target yaw moment Mtb for the braking force control are calculated (S70). A steering-angle changing device (24) and a braking device (36) are controlled based on the target yaw moments Mts and Mtb, respectively (S400 to S430).
