Title: Braking force control device of vehicle
Inventor: OKAZAKI HARUKI
IPC: B60T8/1761
Filed: 1995-09-28
Abstract: PROBLEM TO BE SOLVED: To suppress the pulsation of a brake pedal in a wheel cylinder pressure loose increasing condition following the finish of an ABS control at the vehicle stopping time, by suppressing controlling increase in a brake fluid pressure, when the car speed is made less than a specific valve in the speed reducing time when the wheel locking tendency is decided in the vehicle braking condition. SOLUTION: When a vehicle is running during the ABS controlling, a loose or a sudden pressure increase control, or a loose or a sudden pressure decrease control is carried out, by setting a control amount in a normal ABS control time depending on the difference between the body speeds by sensors SFL to SRR and the like, and the wheel speeds, in an ABS control unit 62. On the other hand, in the vehicle stopping condition, the stopping time is detected, and when the detecting value is less than a specific prescribed value, an extremely loose pressure increase control whose increasing speed is extremely smaller than the step level in the loose pressure increasing speed in an ABS control is carried out, and the pressure increase of a wheel cylinder is carried out through a liquid pressure unit 61 for the next ABS control.  Consequently, the pressure variation in the brake liquid increase time is made small, and the pulsation of a brake pedal 4 can be controlled.

Besides, since the plural fine pipes 6a are bundled, a total opening area is large and since the frequency is low at the time of normal artificial breathing although maximum flow rate is high, flow rate resistance can be kept small. Namely, the operation to be the large impedance at a high frequency but to be the small impedance at a low frequency is provided.
