    • In a vehicle brake control device, a target W/C pressure depending on an amount of operation performed to a brake operating member, exhibits hysteresis due to a forward mapping dataset and a backward mapping dataset. The vehicle brake control device selects the forward mapping dataset or the backward mapping dataset based on the amount of operation performed to the brake operating member, and determines a current value of a current to be supplied to one of first to fourth linear valves. Therefore, it is possible to prevent a wheel cylinder pressure from changing too sensitively to the operation to the brake operating member and from changing even when the driver is not intentionally operating the brake operating member. This makes the driver experience an improved brake feeling.
    • 在车辆制动控制装置中,取决于对制动操作构件的操作量的目标W / C压力由于前向映射数据集和反向映射数据集而呈现迟滞。 车辆制动控制装置基于对制动操作构件的操作量来选择正向映射数据集或反向映射数据集,并且确定要提供给第一至第四直线阀之一的电流的当前值。 因此,即使当驾驶员不是有意地操作制动操作构件时,也可以防止轮缸压力对于对制动操作构件的操作太敏感地改变,并且不会改变。 这使得驾驶员体验到改善的制动感。

    • A vehicle brake control device determines a first duty factor required to achieve a stable rotational speed of motors and a second duty factor required to achieve a change rate of a target wheel cylinder pressure. The vehicle brake control device selects the larger one of the determined duty factors as a for-use motor duty factor to be used in outputting currents to the motors. Therefore, with the stable rotational speed and the change rate of the target wheel cylinder pressure, it is possible to achieve quick response to a request for braking made by a driver while suppressing the electric energy consumption of the motors.
    • 车辆制动控制装置确定实现电动机的稳定转速所需的第一占空比因数和实现目标轮缸压力变化率所需的第二占空比。 车辆制动控制装置将所确定的占空比中的较大的一个选择为用于向电动机输出电流的用途电动机占空比。 因此,通过稳定的转速和目标轮缸压力的变化率,可以在抑制电动机的电能消耗的同时,实现对驾驶员的制动请求的快速响应。

    • When the ABS control is executed by the ABS control portion, the vehicle brake control device calculates the first rotational speeds of the first and second motors necessary to achieve the corresponding pressure increase rates and calculates the second rotational speeds of the first and second motors as the upper limits caused by the unlocking pressure limits. Then the vehicle brake control device controls current values of the currents to be supplied to the first and second motors so that they are rotated in the rotational speeds obtained within a range from the first rotational speeds to the second rotational speeds.

    • A master cylinder which includes a primary piston and a thrust piston disposed within a housing, and defines an intensifying chamber at a location rearward of the thrust piston. An input shaft has a front end which is disposed within the intensifying chamber. The thrust piston is formed with a communication path (discharge passage), and a control valve is disposed between the thrust piston and the front end of the input shaft to open or close the communication path (discharge passage). When the input shaft is driven forward under the inoperative condition shown and the pump is operated to introduce a discharge pressure from the pump into the intensifying chamber, a liquid pressure is generated in the intensifying chamber and drives the primary piston forward, generating a liquid pressure in a liquid pressure chamber. In this manner, a master cylinder can be provided which has a simple and inexpensive construction with a reduced number of parts and which is compact in size. The master cylinder is capable of providing an increased braking force as required by intensifying a master cylinder pressure.
