摘要： A method and a device for the open- and/or closed-loop control of a generator or a dynamo in a vehicle. The generator supplies, at least part of the time, an electric motor located in a braking system, e.g., a pump motor, with electrical power. A main feature is that the generator is activated as a function of the pressure in the brake master cylinder, it being activated as soon as the pressure in the brake master cylinder exceeds an initial threshold value.

摘要： A method and a device for measuring the speed of a pulse-activated electric motor are described. According to this method, the motor is fully activated at time intervals to be determined for a defined measuring time by the circuit element provided for timing and, in this time, the frequency of the current ripples, which is proportional to the motor speed, is measured.

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 a system for detecting the speed of a pump motor of a hydraulic pump system are provided, in which pump system a pump is driven by a pump motor to deliver hydraulic fluid into a pump reservoir. In accordance with the present invention, a pressure signal representing the fluid-delivery activity of the pump is detected, and the pressure peaks within this pressure signal identified.

摘要： A method and device for driving an arrangement, in a vehicle, that delivers a pressurized medium in a brake system, the pressurized medium being delivered in at least one brake circuit of the brake system, and a pressurized medium volume available in the brake circuit being dependent upon the driving of the arrangement delivering the pressurized medium. In this context, the arrangement delivering the pressurized medium is driven as a function of the vehicle speed so as to effect a correlation between the vehicle speed and the pressurized medium volume available in the brake circuit. This means, in particular, that the vehicle speed and the pressurized medium volume available in the brake circuit are linked in such a way that, with rising vehicle speed, the available volume of pressurized medium in the brake circuit is increased, and/or with falling vehicle speed, the available volume of pressurized medium in the brake circuit is decreased. This ensures that a sufficient volume of pressurized medium is available, even in the case of heavy volumetric consumption during a brake application, in which the arrangement delivering the pressurized medium does not adequately supply the pressurized medium.

摘要： An activation signal of a pump of a braking system is created as a function of a pressure gradient, preferably from a pressure accumulator. In this context, the switched-on time of a pulse-width modulated signal within an activation clock cycle is varied, taking into consideration the accumulator pressure gradient, in order to activate the pump. This is done by addressing a switching arrangement by way of a control unit. Activation as a function of the pressure gradient can be accomplished alternatively to or in combination with activation as a function of the generator voltage of the pump motor.

摘要： A hydraulic vehicle brake system in which normal service brake operation can be carried out by using external hydraulic energy, and in the event of a lack of external hydraulic energy, auxiliary brake operation by muscle power is possible, with a hydraulic transmission that comes from a master cylinder that can be actuated by means of the brake pedal. The external hydraulic energy is stored, for example, in an accumulator with a gas buffer, which can lead to a gas content in the hydraulic fluid for the service brake operation. The system includes a dual-circuit master cylinder associated with those wheel brakes of a vehicle axle that make a higher contribution to the vehicle deceleration and at the same time, cylinder/piston devices are installed between these wheel brakes and their associated service brake valves for the purpose of preventing hydraulic fluid from getting into these wheel brakes from the external energy source. The advantage is that neither gas nor air is carried into the wheel brakes where it could lead to the formation of bubbles in the event of a pressure drop and would be disadvantageous for an auxiliary brake operation by the master cylinder. The cylinder/piston devices increase the operational safety of the vehicle brake system when braking by muscle power.
