Abstract: A driver assistance system and a method for automatically logging a transition of the responsibility during a status change between fully automatic operation and manual operation of a motor vehicle is provided. The driver assistance system and the method include an event data recorder with a data storage and with a control unit. The control unit is designed such that a time-limited recording of log data is triggered by means of the data storage when a pre-warning signal, which announces the status change between fully automatic vehicle operation and manual vehicle operation, is transmitted to the control unit. In this manner, a secure logging process of the transition of the responsibility is ensured.

Abstract: The invention relates to a driver assistance system (6) and a method for automatically logging a transition of the responsibility during a status change (W) between fully automatic operation and manual operation of a motor vehicle (4), comprising an event data recorder (2) with a data storage (10) and with a control unit (8), wherein the control unit (8) is designed such that a time-limited recording of log data (P, B) is triggered by means of the data storage (10) when a pre-warning signal (V), which announces the status change (W) between fully automatic vehicle operation and manual vehicle operation, is transmitted to the control unit (8). In this manner, a secure logging process of the transition of the responsibility is ensured.

Abstract: The invention relates to a method for improving the driving stability of a motor vehicle in which driver-independent braking interventions are triggered if a critical driving situation is to be expected on the basis of route information and instantaneous position data of the motor vehicle, and to a corresponding system. According to the invention, the driver predefines, via a human/machine interface, information about the maximum coefficient of friction to be utilized, which is used as the basis for the prediction of a critical driving situation.

Abstract: A method and a device for triggering an emergency call in a vehicle equipped with an airbag. The device can be retrofitted in a vehicle equipped with an airbag to provide an emergency system which, in the event of an airbag being triggered, sends an emergency call (Ecall) to a suitable emergency call center in order to initiate auxiliary measures as may be necessary.

Abstract: The present invention relates to a method of determining forces and torques acting on a riding vehicle. The invention is characterized in that measuring signals from acceleration sensors are evaluated which are fitted, preferably in longitudinal, transverse and vertical alignment, to one or more selected points on the vehicle, and that other signals are evaluated which represent the spatial angular velocity of the vehicle and its time derivative (rolling, pitching and/or yaw velocity and rolling, pitching and/or yaw acceleration) or at least some of these variables, and that a mathematic model of the vehicle is provided in which forces and torques acting on the vehicle or at least selected components of these forces and torques are determined from the sensor signals.

Abstract: A combined service and parking brake includes a hydraulic actuating device (1) which has a brake cylinder (2) and a brake piston (3), and a hydraulically operable locking device (8) for fixing the brake piston (3) in the applied condition. According to the present invention, the locking device (8) is operable by a pressure impact through the hydraulic supply line (5) provided for service brake operations, and the pressure impact is in a pressure range that is above the pressure range provided for service brake operations.

Abstract: A brake system for automotive vehicles with electric drive is operable by an actuating pedal and uses hydraulic friction brakes to augment the braking effect generated by the electric drive motors. The coaction of the drive motors with the hydraulic friction brakes is controlled by an electronic controller. In order to largely conform the pedal characteristics of the mentioned brake system to that of a standard passenger car, an actuating pedal (5) is in force-transmitting and travel-transmitting connection with a spring (8) exhibiting a predetermined characteristic curve, and the master brake cylinder (11), uncoupled from the actuating pedal (5), is operable by an electromagnet (9) which is responsive to the controller (70). If the master brake cylinder accommodates two pressure cheers, a single valve is arranged in or on the master cylinder housing, and acts as both a bypass valve and a differential-pressure valve.
