摘要:
A device with a starter-generator for internal combustion engines, the combustion engine having a centrifugal mass for stabilizing its smoothness of running, with at least one first nonpositive clutch and a flywheel generator, which can be actuated by means of an electrical energy source and is in effective connection with a selectable gearbox, the nonpositive clutch being provided between the flywheel generator, which can be actuated by means of an electrical energy source, and the combustion engine, and the flywheel generator forming the centrifugal mass of the combustion engine.
摘要:
A method and a device for handling errors of software modules for redundantly designed systems in vehicles in order to optimize error handling for redundantly designed systems in vehicles, so that errors are detected and error handling measures are introduced. In addition, error handling is configured in such a way that it can be used for a plurality of software-controlled applications that run on a control device. Furthermore, a device for performing the method uses direct and/or indirect redundant input data to determine the adjusted input data for the software modules.
摘要:
A method for operating an electronically actuated drive train in a motor vehicle includes the steps of determining drive control signals for actuating a drive unit and gearbox control signals for actuating a manual gearbox from a power request of the driver of the vehicle, providing a predefined or predefinable driving style which can be selected from a range from minimum energy or fuel consumption up to maximum power output, taking the driving style into account in the determination of the drive control signals and the gearbox control signals, taking the local position of the motor vehicle into account in the determination of the drive control signals and the gearbox control signals.
摘要:
A control system for a vehicle having a plurality of signal processing levels and actuators, in particular for brake, steering, engine and gearbox, for converting actuation signals and a method for controlling a vehicle. The system employs the following levels: an input level for continuous stipulations or an input level for discrete stipulations and an automation level for generating setpoint value signals, a predictive level and/or a reactive level for correcting the setpoint value signals, a coordination level for converting the set point value signals into actuation signals, and an execution level with the actuators. The actuators are connected to one another and to the coordination level by a fault-tolerant, redundant and bidirectional databus. Measures for redundant signal processing are taken, and data is transmitted in a fault-tolerant, redundant and bidirectional fashion.
摘要:
A method and a circuit functionally test a semiconductor component. The functional test is performed with galvanic isolation by using a transformer. The test itself is based on determining the frequency-dependent impedance of a series circuit of capacitors and inductors using the semiconductor component itself. The impedance is strongly influenced by the conduction state of the semiconductor component, in other words, by the instantaneous conductivity or blocking capability of the semiconductor component.

This invention relates to an arrangement for preventing unintended rolling of a vehicle. If, in the case of a vehicle which is parked properly (with the parking brake activated), it is determined that the parking brake is released, a brake pressure is generated which ensures the stoppage of the vehicle. For this purpose, a control device actuates relay valves to establish a fluid connection between a pressure accumulator and the wheel brakes. The fluid connection is maintained until a brake pressure is applied by the wheel brake cylinders which ensures the stoppage of the vehicle.

This invention relates to a transport device for a motor vehicle or partially assembled motor vehicle during the production process. The transport device is configured to receive a motor vehicle or partially assembled motor vehicle, said motor vehicle or partially assembled motor vehicle being conveyed by means of the transport device to the various work stations. The transport device, which is continuously supplied with power during the production process, has a terminal for supplying power to the on-board electrical system of the motor vehicle or partially assembled motor vehicle to be conveyed by the transport device. This terminal can be connected up to the on-board electrical system of the vehicle or partially assembled vehicle.
