A hydraulic vehicle brake system having at least one brake pedal, a pedal-travel simulator, at least one hydraulically operable wheel-brake unit and a switching valve between the brake pedal and the pedal-travel simulator. The switching valve is adjustable between a first switching position, in which the brake pedal is connected to the pedal-travel simulator and decoupled from the wheel-brake unit, and a second switching position, in which the brake pedal is decoupled from the pedal-travel simulator and the brake pedal is connected to the wheel-brake unit. In the first switching position, a pressure-supply unit is connected at the same time to the wheel-brake unit.

Energy transmission device and energy transmission system

A method for starting up a vehicle includes driving a first wheel with an internal combustion engine vehicle drive and driving a second wheel with a hydrostatic additional drive. The hydrostatic additional drive has an adjustable hydraulic pump driven by the internal combustion engine, and at least one hydraulic motor coupled hydraulically thereto. The method further includes increasing and regulating a supply pressure of the at least one hydraulic motor in dependence on an accelerator pedal; determining a non-zero rotational speed of the first wheel; and synchronizing a rotational speed of the second wheel with the determined rotational speed of the first wheel. The method further includes increasing and regulating a supply pressure of the at least one hydraulic motor in dependence on an accelerator pedal; determining a non-zero speed of the vehicle; and adapting a rotational speed of the second wheel to the determined speed.

A device and a method for controlling an engine. On the basis of a first variable which characterizes the injection quantity and a second variable which characterizes the angular position at which the injection quantity is metered, a third variable which characterizes the torque supplied by the engine is determined. Furthermore, on the basis of a fourth variable which characterizes the driver's intent, a fifth variable which characterizes the torque desired by the driver is determined. The third variable and the fifth variable are analyzed for the purpose of fault monitoring.

Method and device for the control of an internal combustion engine

A method and a device is described for controlling an internal combustion engine using fuel metering. The fuel metering is divisible into at least a first partial injection and a second partial injection. In the second partial injection, a fuel quantity variable, characterizing the fuel quantity injected in the second partial injection, is corrected on the basis of at least one pressure variable, characterizing the fuel pressure, as well as of the fuel quantity variable and at least one further variable.

Method and device for controlling an internal combustion engine

The present invention relates to a device and a method for dividing up a total fuel amount, which is to be injected into the combustion chamber of a cylinder during a combustion cycle, into a plurality of injections. To this end, a first fuel amount, which is to be injected during a first injection is determined, a fourth, minimum fuel amount for a third injection is determined, and the total fuel amount minus the first fuel amount is compared to the fourth, minimum fuel amount. When the total fuel amount minus the first fuel amount is greater than or equal to the fourth, minimum fuel amount, the first fuel amount and a second fuel amount, which is to be injected into the combustion chamber of the cylinder during a second injection, are set to zero, and a third fuel amount, which is to be injected during a third injection, is set to the total fuel amount.

Method and device for injecting fuel in an internal combustion engine

A method and a device are described for controlling an internal combustion engine, particularly an internal combustion engine that has a common-rail system. At least one pump delivers fuel into an accumulator. A pressure in the accumulator is detected. A distinction is made between at least one first operating state and at least one second operating state based on at least one speed signal and/or one load signal. At least one first pressure-control device is used to adjust the pressure in the at least one first operating state. At least one second pressure-control device is used to control the pressure in the at least one second operating state.

A vehicle brake system with a hydraulic brake booster. A booster pressure which is required for operating the brake booster is produced by throttling a flow of pressure medium which is supplied by a pump. For this purpose, a throttle valve is arranged between a pressure line which is connected to the pump and a return line which leads back to the pump, the adjustment of said pressure valve involves a building up of booster pressure in the pressure line by a solenoid, which booster pressure is applied to the brake booster. An electronic control unit which is connected to at least one sensor which outputs variable electric signal serves to control the throttle valve, the sensor detects activation of the brake pedal. For example, a pressure sensor which as a function of the boosting pressure supplies signals to the control unit which is developed to form a pressure controller and controls the throttle valve can be connected to the brake booster.

Vehicle brake system

A disk brake having an electromagnetic friction clutch that can be brought into controllable frictional engagement with a brake disk. The friction clutch can act on a device for generating hydraulic pressure independent of the direction of rotation, and this pressure can act upon a clamping device for operating friction linings. To press the friction linings against the brake disk, energy is taken from the rotating vehicle wheel by means of the friction clutch and metered to the clamping device with pressure fluid as the energy carrier. The friction brake can be used in passenger cars, for example.
