    摘要: A method and a device for controlling and/or regulating an electric motor. Such electric motors are used for example in motor vehicles in the form of pump motors. In general, the electric motor is supplied with electrical energy from a battery and/or using a generator. The controlling and regulation take place using a high-frequency pulse width modulation (PWM). When the electric motor is started, the PWM is used to continuously increase the motor current required for the operation of the electric motor, e.g. beginning from 0.

    摘要: A method for determining the rotary speed of an electrical machine, especially of a direct current motor, which is controlled in PWM operation, the tracking voltage of the electrical machine being measured and the rotary speed being ascertained from that. The rotary speed fluctuations are able to be substantially reduced if the electrical machine is controlled using a control signal which has a PWM phase, in which the electrical machine is periodically switched on and off using a prespecified pulse duty factor, and which has a measuring phase in which the electrical machine is switched off. The rotary speed is measured in the measuring phases, in this instance, and is calculated in the PWM phases based on a model.

    摘要: A method and apparatus for activating a pump of a braking system for delivering a pressure medium, in which the creation of the activation signal, in particular the switch-on signal for the pump, is dependent on at least one condition. Creation of the switch-on signal of the pump is dependent on a pressure gradient variable, in particular on an accumulator pressure gradient. On the one hand this makes possible compensation for disturbances, for example the influence of temperature on the pressure medium, which is expressed as a small pressure gradient; and on the other hand it prevents the pressure from falling greatly below a lower threshold value in the event of a high volume demand request, i.e., prevents a severe pressure drop and thus a large pressure gradient.

    摘要: A method for determining a functional state of a pressure build-up valve of a hydraulic brake booster of a brake system, having the following steps: comparing an activation intensity of an activation of a brake activating element of the brake system to a predefined minimum activation intensity; if the brake activation intensity is less than or equal to the minimum activation intensity, determining the functional state, taking into account a pressure change over time in at least a partial volume of the hydraulic brake booster; if the brake activation intensity is greater than the minimum activation intensity, determining the functional state, taking into account an operating mode which is predefined for a pressure reduction valve of the hydraulic brake booster. A function monitoring device for a pressure build-up valve of a hydraulic brake booster of a brake system is also described.
