摘要： A method and system for measuring pressure in a pressure regulation unit of a motor vehicle braking system, without using pressure sensors and having a motor pump unit with an electric motor and a hydraulic pump. The steps include producing a relative motor characteristic diagram for a series of the units. The diagram includes the data of motor-rotational-speed-dependent parameters, intensity of the motor actuation, and parameters relating to the level of the motor load. Further steps include; determining individual motor characteristic variables, determining a current rotational-speed-dependent parameter of an individual motor during the operation of the pump, and calculating a pressure which is characteristic of the braking system, by means of the diagram parameter of the individual motor and the value of the current motor actuation which determines the intensity of the motor actuation, wherein the individual motor characteristic variables are taken into account.

摘要： A method for controlling and/or regulating an electronically triggerable vehicle brake system, operating on the return principle, and to such a brake system in which by an adapted triggering of the drive motor for the pressure generator, the pumping quantity of the pressure generator is varied such that the difference between these flows of pressure medium to and from the master cylinder assumes a minimal value, preferably a value of zero. To that end, the driving rpm of the pressure generator is preferably varied. The trigger signal for the drive motor can be ascertained by an electronic control unit from measurement outcomes from sensors within the vehicle brake system, or it can be estimated with the aid of a hydraulic volume model stored in memory in the control unit. The trigger signal can be controlled or regulated.

摘要： To make a brake device generate a required braking force, a hydraulic control section switches, according to the relative magnitude between the required braking force and a braking force exerted by braking operation, between drive of a pump motor and non-drive of the pump motor and a master cut valve reduces the flow of brake fluid in the direction to a master cylinder. By this, a wheel cylinder maintains hydraulic pressure capable of generating the required braking force. As a result, the pump motor is not necessarily always driven when the required braking force is generated, and the operating time period of the pump motor is reduced. As a result, a load on the pump motor is reduced to enhance durability of the pump motor.
