Abstract: The present disclosure relates to a method comprising the following steps: receiving sensor data which have been generated by a sensor system, in a control module of a vehicle computer; inputting the sensor data into a safety algorithm to detect safety-relevant objects; inputting the sensor data into a comfort algorithm to detect comfort-relevant objects; estimating future states of the objects using an environment model which represents the environment of the vehicle and in which the objects are stored and tracked over time; calculating a safety trajectory taking into account safety rules and a comfort trajectory taking into account comfort rules based on the estimated future states of the detected objects; using the comfort trajectory to control the vehicle if the comfort trajectory satisfies the safety rules; and using the safety trajectory to control the vehicle if the comfort trajectory does not satisfy the safety rules.

Abstract: A method for assisting a driver during the deactivation of a highly automated driving mode of a vehicle. In this context, a takeover signal, which represents a takeover of control of the vehicle by the driver, and auxiliary information are read in. The auxiliary information includes image information representing the driver and/or vehicle-control information representing a control of the vehicle by the driver. In a further step, a degree of attentiveness of the driver is determined, using the takeover signal and the auxiliary information. Finally, using the degree of attentiveness, an assistance signal is output to assist the driver during the takeover of control, by activating at least one driver-assistance function of the vehicle.

Abstract: A method and a system for controlling a driving function of a vehicle, whereby in a first operating state, the driving function is controlled by a vehicle guidance system, and in a second operating state, the driving function is controlled by a command of a driver, a transition from the first operating state to the second operating state being accomplished with the aid of an orderly handover through a preset handover procedure when it is recognized that a predetermined first condition is fulfilled, or with the aid of a handover in a fallback solution when it is recognized that a predetermined second condition is fulfilled.

Abstract: The disclosure relates to a method for operating a motor vehicle brake system that comprises at least one electronic parking brake having at least one actuator, wherein in the presence of a first switching signal at a switching signal input the actuator is controlled so as to activate the parking brake. It is provided that the switching signal input in a normal operating mode is released so as to apply optional switching signals and in a safety operating mode is set to a second switching signal that is different from the first switching signal so that the process of controlling the actuator so as to activating the parking brake is prevented. The disclosure further relates to a control device for a motor vehicle brake system.
