Abstract: A vehicle door has an easy exit feature that holds the vehicle door in a desired latched position by applying a latching torque with a controllable damper. An evaluation and control unit detects the desired latched positions by evaluating an instantaneous door movement sensed by a sensor system, and accordingly actuates the damper. The evaluation and control unit releases the latched position after a corresponding activation has been detected. The easy exit feature is embodied as a variable latching function, and applies a maximum holding force to the vehicle door by way of the damper and locks the vehicle door in the desired latched position.

Abstract: A utility vehicle has an electronically controlled drive train which has at least one drive unit, one steering system and one braking system. In addition, the motor vehicle has a maneuvering assistance system with a display device, an input device and a control system. The display device displays an actual orientation and an actual position of the vehicle as well as the relatively close surroundings of the vehicle on a monitor. The input device inputs a desired orientation and a desired position for the vehicle. The control system processes a maneuvering algorithm and at the same time actuates the drive train to transfer the vehicle from its actual orientation and actual position into its desired orientation and desired position taking into account the vehicle surroundings.

Abstract: The present invention relates to a control system (7) for a vehicle combination composed of a towing vehicle and a trailer for picking up, transporting and setting down a frame which can be positioned on supports and have a payload loaded onto it, wherein a path computer (8) is provided which calculates a path which, in order to pick up the frame (4) calculates a path which leads the trailer backward under the frame. A particularly reliable system is obtained if a first input device (10) is provided, by means of which an actual position and an actual orientation of the frame can be input into the path computer (8), and if a second input device (11) is provided by means of which an actual position and an actual orientation of the trailer can be input into the path computer (8).

Abstract: A safety device for, in particular, nonrailborne vehicles, having a monitoring device to monitor a hazardous area and additionally the road area, located on the opposite side of the hazardous area viewed from the vehicle and adjoining the hazardous area. Obstacles in the hazardous area and/or road area are detected. An output signal is brought about if an obstacle which prevents the hazardous area being traveled through completely has been detected.

Abstract: A device for determining the seat weight on a vehicle seat assembly, provided with at least one seat rail on which the seat is mounted, and with a weight sensor that interacts with the seat rail. The at least one seat rail is fastened to the vehicle in a fixed manner via the weight sensor and at least one additional fastening device. The seat rail (2) is embedded inside an elastomer structure (5) that serves as a vibration damper while also acting as a step protection and overload protection.

Abstract: A steering system with a steering adjustment unit, based on the “steer by wire” concept, with an additional system for an automatic emergency stopping maneuver is provided. In situations that cannot be controlled by the driver, preset data from a preset or storage arrangement are transmitted to a braking system and a steering adjustment unit, with the vehicle then being braked and steered according to the preset data.

Abstract: A method and apparatus for registering travel data of a motor vehicle with an electronically actuated drive train, utilizing a sensor device for determining actual vehicle data which relates to the travel dynamics, a time-registration device for generating time data, a position-determining device for determining position data of a motor vehicle, and a storage device for at least temporarily storing the actual vehicle, time and position data. The storage device is coupled to operator control elements for the driver-end generation of activation signals for influencing the drive train, and an actuation device for the activation-signal-dependent generation of actuation signals for the drive train. The storage device is designed to store at least temporarily the activation signals and the actuation signals.

Abstract: 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.

Abstract: A brake system for a vehicle can be operated without a driver. It has a service brake device, a parking brake device and an emergency braking device. At least the wheel brake devices of the wheels of one axle of the vehicle have emergency brake actuators which switchover the assigned wheel brake devices into the braking state as a result of the triggering of an emergency braking operation. The emergency braking operation can be triggered either manually by means of an emergency operator control device or automatically by means of a monitoring device if the latter has detected an unacceptable operating state of the vehicle in the driverless operating mode.

Abstract: 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.
