摘要:
A boost state of an upstream side brake fluid pressure producing device that boosts a braking operation force of a braking operation member and produces a fluid pressure in a master cylinder is adjusted according to a refluxing brake fluid characteristic of brake fluid that refluxes to the master cylinderby a pressure decrease control and an outflowing brake fluid characteristic of the brake fluid that flows out of the master cylinder into a wheel cylinder by a pressure increase control, and variation of the braking operation member is suppressed. It is therefore possible to suppress an occurrence of vibration and noise of the brake pedal during the ABS control.

A braking system for a vehicle is operative to apply a friction brake force to at least one wheel of the vehicle. The braking system includes a master cylinder is in fluid communication with a reservoir of brake fluid and in fluid communication with the hydraulic brake device. According to one aspect, the braking system includes an electric brake force generator which moves the brake fluid within the master cylinder to deliver brake fluid to the friction brake device in response to a first predetermined displacement of a brake pedal.

In a brake control system, a power supply portion supplies a voltage to a plurality of actuators. When a first actuator is supplied with a voltage equal to or higher than a first minimum operating voltage from the power supply portion, the first actuator operates to perform a first function. When a second actuator is supplied with a voltage equal to or higher than a second minimum operating voltage from the power supply portion, the second actuator performs a second function. The first minimum operating voltage and the second minimum operating voltage are set to be different from each other by a predetermined value so that the first actuator and the second actuator stop operating in a predetermined sequence with a decrease in the supplied voltage.

摘要:
The invention relates to a method for controlling a hydraulic vehicle braking system with active hydraulic brake force assistance, in which the driver can control brake pressure in a main brake cylinder (1), by means of an operating device, preferably a brake pedal (3) and in which the pressure controlled by the driver is assisted by means of an active hydraulic pressure servo unit, in particular a hydraulic pump, whereby a brake command or a presumed brake command is determined and on a brake command or a presumed brake command being recognised an isolating valve (6) arranged in a line (5) connecting the main brake cylinder (1) and the hydraulic pressure servo unit (16) is opened or remains open and the pressure servo unit (16) is regulated such as to generate a pressure.
