Abstract: A device for rapid short-circuit protection in a power semiconductor is described. It has at least one power semiconductor (10, 38) via which a load current (IL) may be applied to at least one electric load (24). The current detection means (14, 18, 46) provide a measure (VIS) of the load current (IL) applied to the electric load (24). A semiconductor protective circuit (30, 32, 34, 36) triggers the power semiconductor (10, 38) to protective operation in the event of an imminent impairment of the power semiconductor (10, 38).

Abstract: A device for error detection in a multi-voltage vehicle electrical system is proposed having a power distributor (40) that affects the supply of power to at least one electrical load (46) via at least one output (45), having detection means (41, 42, 44) that detect at least one electrical variable at the output (45), and having at least one signal processing unit (44) that compares the electrical variable (54, 56) to at least one limiting value, the detection of an error state being based on this comparison.

Abstract: The movement of a vehicle is controlled by actuating actuators which apply a braking force to the wheels. For this purpose, the rotational speeds of the wheels, the steering angle and at least one of the lateral acceleration and the yawing movement of the vehicle are detected. A first module is configured so that the actuators are actuated by means of the actuation signals with the effect of controlling a first variable. The second module is configured so that signals for influencing the actuation signals are formed with the effect of controlling a second control variable. In order to obtain this second control variable, at least the variable which represents the steering angle is processed. The second controller component brings about a control of a variable which is determined at least as a function of the lateral movement or the yawing movement of the vehicle.

Abstract: Detection means are provided which detect the rotational movements of the wheels, a variable which represents the steering angle, and at least one variable which represents the lateral movement and/or the yawing movement of the vehicle. Signals for influencing actuators for braking the wheels are formed by controller means as a function of the detected data in such a way that a control variable which is dependent on at least the detected lateral movement or yawing movement of the vehicle is adjusted to a desired range of control variables, that is to say the actuators are influenced in such a way that the control variable is kept within a desired range. This desired range is defined by two specific limit values.

Abstract: A movement variable which represents the movement of a vehicle is controlled by actuating at least one actuator for applying a braking force to the wheels. Controller means use controller internal variables to form signals for influencing the actuators with the effect of adjusting a control variable. The controller means has a first area adapted to the respective selected sensor configuration in such a way that the controller-internal variables are formed on the basis of the sensor signals, and a second area for processing the controller-internal variables independently of the selection of the sensor configuration. As a result, simple adaptation with low development and application outlay to a wide variety of sensor configurations is possible.

Abstract: A brake controller is connected downstream of a primary vehicle dynamics computer and has a channel for controlling the yaw velocity at a desired value, and a channel for limiting the sideslip angle. The computer prescribes the desired value and the limit value, and determines which channel is effective on the basis of the driving situation. The two channels generate a control signal which is routed via a control amplifier having a proportional component and a differential component. An actuating signal which is used to input braking pressure at the wheel brakes is formed from the resulting signal components, the instantaneous driving situation being assigned in both cases to one of a plurality of classes, and this assignment being co-used to determine the wheels at which braking pressure is input.
