摘要:
A method for operating an electrically controllable brake system for a motor vehicle having at least one electrically actuated valve arrangement for setting a pressure difference between a second brake pressure and a first brake pressure, wherein in a first time interval a predetermined first pressure difference is set and an associated first power consumption value of the pump is identified; in a second time interval a predetermined second pressure difference is set and an associated second power consumption value of the pump is identified; a correction value is obtained from the first power consumption value and the second power consumption value; the correction value is taken into account for setting a set-point value for the pressure difference.

A hydraulic brake system for a land vehicle, having a master cylinder, which is actuable by the driver by means of a pedal directly or via a brake booster disposed downstream of the pedal, for generating brake pressure in two brake circuits, each of which comprises two wheel brakes, wherein a hydraulic connection between the master cylinder and the wheel brakes is to be established or blocked by valve arrangements in dependence upon trigger signals from an electronic control unit in order to implement normal braking operations brought about directly by the driver or braking operations influenced by the electronic control unit in dependence upon measured variables, which are supplied to the electronic control unit and reflect the vehicle behaviour and/or the driver request, in that the brake pressure characteristic in the wheel brakes is varied by activating the valve arrangements associated therewith, wherein the electronic control unit is devised and programmed in such a way that, in order to set a brake pressure characteristic required for a specific vehicle behaviour, it supplies trigger signals, by means of which the setting of a respective brake pressure characteristic in the two brake circuits in predefined pressure stages (delta-p) is staggered in terms of time by a substantially predefined time stage (delta-t).

A method for preventing the driven wheels of an automotive vehicle from spinning provides that whenever one of two driven wheels of one axle of the vehicle has a lower friction coefficient with the road surface than the other wheel of said axle and the one wheel shows a spinning tendency, brake pressure is built up at said wheel, with the rotational speed of the other wheel being measured, and whenever the rotational speed exceeds a specified value with respect to a vehicle reference speed, the brake pressure at the one wheel is reduced or maintained constant.

An anti-locking brake system for a land vehicle, which is set up in particular for traction control and vehicle dynamics control, comprises a pump (42) for actuating a wheel brake (37) which removes brake fluid from a brake pressure generating unit (31) and supplies it to the wheel brake (37), wherein a first valve arrangement (1) blocks in a non-actuated (normal) position (1.1) the connection between the brake pressure generating unit (31) and an input connection (42e) of the pump (42) and in at least one actuated position (1.3) establishes a primary flow connection (A), a first electromagnetic valve (50) establishes in a non-actuated position (50.1) the connection between an output connection (42a) of the pump (42) and the brake pressure generating unit (31), and blocks it in an actuated position (50.2), a second electromagnetic valve (39) blocks the connection between the wheel brake (37) and the input connection (42e) of the pump (42) in a non-actuated position, and in an actuated position establishes it, and a third electromagnetic valve (38) establishes the connection between the output connection (42a) of the pump (42) and the wheel brake (37) in a non-actuated position (38.1) and blocks it in an actuated position (38.2). To generate a more accurate pressure modulation during the operating phase “maintain pressure” (II), the third electromagnetic valve (38) is in the actuated position during said operating phase.
