摘要:
The invention relates to a braking method for a vehicle comprising at least one front wheel and at least one rear wheel, a hydraulically actuatable brake being provided on the front wheel and the rear wheel and an automatic parking brake (1) being provided on the rear wheel. The object of the present invention is that of providing a braking method, by means of which an optimal braking pressure can be built up as rapidly as possible, in particular in an emergency braking procedure, whilst making the system as cost-effective as possible. To achieve this object, in a first step of an initiation phase of the braking method, the front wheel is braked by the hydraulically actuatable brakes and the rear wheel is braked exclusively by the automatic parking brake.

A method of operating a hydraulic brake system is described. A method of operating a hydraulic brake system of a motor vehicle having a mechatronic brake booster to boost a hydraulic pressure generated in a brake master cylinder of the brake system by a brake pedal of the motor vehicle determines whether a propulsion request is present during operation of the motor vehicle and actuates the mechatronic brake booster when a propulsion request has ended or been substantially reduced. During a predetermined time interval after the propulsion request has ended or been reduced, the mechatronic brake booster is operated at a minimum intensity such that no braking effect occurs during the predetermined time interval, unless a braking request occurs.

The invention relates to a method for carrying out an automatic braking action, whereby at least one variable representing the actuation of the brake pedal is determined and an automatic braking action is then triggered if at least one threshold value (brake pedal actuation-threshold value) of the variable representing the actuation of the brake pedal is exceeded, whereby the brake pedal actuation threshold value is altered and/or the variable representing the brake pedal is weighted according at least one driver action, especially a detected movement of the driver's foot before an actuation of the brake pedal of the considered braking action and/or prior to the considered braking action.
摘要:
A vehicle braking apparatus that can exert high braking performance during vehicle braking is implemented by a control mode that can be realized in a braking apparatus (10) of usual hardware. In controlling the braking apparatus (10) of a vehicle, a climb rate of a wheel cylinder braking oil pressure (Pw) is decreased smaller than a climb rate corresponding to a climb rate of a master cylinder oil pressure (Pm) from a time point at which the wheel cylinder braking oil pressure (Pw) reaches a predetermined threshold value. The time point at which the wheel cylinder braking oil pressure (Pw) reaches the predetermined threshold value (P3) is estimated based on the climb process of the master cylinder oil pressure (Pm) or directly detected.

The invention relates to a method for determining at least one, preferably however several driver-independent intervention(s) in a vehicle system, using a risk calculator, whose input is supplied with predetermined vehicle data, environmental data, current vehicle and driver data, occupant data or data of persons outside the vehicle, or similar. The risk calculator issues an evaluation of the risk situation of the vehicle and its occupants or the persons outside the vehicle based on said data and in accordance with the evaluation and optional additional criteria or weightings outputs control signals, which control actuators. The latter modify or trigger the driving behaviour of the vehicle and/or the occupant protection system and/or protection means for other traffic participants (pedestrians, cyclists etc.) in such a way that maximum protection is obtained for the persons and the vehicle according to a priority activation.
