| 摘要 |
The present invention relates to a brake control device for a semi-brake-by-wire control system that may eliminate a feeling of discomfort of pedal operation when the system is started after depression of the brake pedal. The brake control system is provided with a master cylinder (4); a wheel cylinder (12); a stroke simulator (6); a wheel cylinder cut valve (8); a stroke simulator cut valve (9); and a brake controller (14). The stroke simulator (6) produces a pedal reaction force by a fluid pressure of the master cylinder (4). The wheel cylinder cut valve (8) selectively opens and closes the connection between the master cylinder (4) and the wheel cylinder (12). The stroke simulator cut valve (9) selectively opens and closes the connection between the master cylinder (4) and the stroke simulator (6). The brake controller (14) closes the stroke simulator cut valve (9) when the system is started after depression of the pedal, and opens the stroke simulator cut valve (9) when the fluid pressure generated by the master cylinder (4) increases ( FIG. 2 ). |
