Abstract: A global positioning signal based learned control event prediction method and apparatus includes a learning auxiliary module connected to a communication bus of a vehicle. The arrangement stores events and event locations using global positioning signals for a vehicle traveling along a path. When the vehicle travels the same path a second time, the detected events and event locations are determined. When the events match at the same event locations, a predictive action is determined for a future occurrence of the vehicle approaching the event location. Thus, as the vehicle approaches the event location, the predictive action, for example pre-filling of the vehicle brakes or pre-tensioning of the seat belts occurs.

Abstract: A method for improving the efficiency of a driving dynamics regulating system which intervenes in the driving operation in critical driving situations by automatic braking intervention at selected wheels. It is possible for the reaction speed of the brake system 3 to be considerably increased if, before the actual regulating intervention, the imminent critical driving situation is already detected and a slight preparatory brake pressure is already built up at at least one wheel at which a future regulating intervention is expected.

Abstract: To improve the control behavior of an automotive vehicle control system, such as an anti-lock system (ABS), a driving stability control system (ESP, ASMS, DDC), etc., in a brake system which includes a master cylinder, inlet and outlet valves for pressure modulation, a low-pressure accumulator, and a hydraulic pump for returning the pressure fluid discharged, when a wheel becomes unstable and upon commencement of the ABS control, that branch of the control system to which the unstable wheel is connected is temporarily uncoupled from the master cylinder pressure (pHZ) or initial pressure by closing the pressure fluid conduit in the direction from the wheel brakes to-the master cylinder, and a relatively quick rise of the braking pressure and a quick approach of the wheel braking pressure to the master cylinder pressure (pHZ) and, thus, the wheel lock pressure level is caused by returning pressure fluid from the low-pressure accumulator into this branch. A special valve which can provide a connection between the master cylinder and the suction side of the hydraulic pump is switched over to open-passage-only after the low-pressure accumulator has been emptied at least in part, or as required.

Abstract: [Problem] The present invention provides a vehicle brake system capable of shortening a delay time from time at which an execution request of a pre-crash brake executed by actuation of an electric booster is sent to time at which the pre-crash brake is actually actuated.
[Means for Resolution] In a vehicle brake system (1) including: a hydraulic unit (20); a braking control section (90) for controlling the hydraulic unit (20); a master cylinder (14); an electric booster (10); a booster control section (100) for controlling the electric booster (10); and a pre-crash brake execution determination section (110), the pre-crash brake execution determination section (110) sends information on a specified target value (P_tgt) for decelerating a vehicle to the booster control section (100) and the braking control section (90). When a change amount (ΔP) of the target value (P_tgt) received from the pre-crash brake execution determination section (110) exceeds a specified threshold value (ΔP_thr), the booster control section (100) drives the electric booster (10) prior to a command from the braking control section (90) and executes preceding brake control for generating a specified brake hydraulic pressure to a wheel cylinder.

Abstract: A pre-filling device for a braking system. The pre-filling device includes a pre-filling channel, a pre-filling pressure being inside the channel when the braking system is in a rest and hydro-boost position, and a mechanical valve configured to be opened following a transition from the rest and hydro-boost position to a working position of the braking system; and a hydraulic valve cooperating with the mechanical valve setting the pre-filling pressure inside the channel. The hydraulic valve includes in a first area, facing the mechanical valve, a hole communicating with the channel, and in a second area, hydraulically isolated from the first area, a preloaded resilient element in a chamber held at atmospheric pressure. The hydraulic valve is configured to be connected or not to be connected, by a reciprocating movement inside the channel, to a hydro-booster device and to keep a predetermined pre-filling pressure upon varying of the hydro-boost pressure.
