Embodiments create methods and computer programs for a monitoring entity and a communication component, a monitoring entity, a communication component, a system and a vehicle. The method () for a monitoring entity () for monitoring at least one communication component (), wherein the communication component () is configured to communicate with one or more other communication components () in an event-based manner via a data bus (), comprises regularly checking () the function of the communication component () using the monitoring entity. The method further includes cyclically communicating () with at least one other monitoring entity () assigned to another communication component () in order to monitor the function of the communication component (), the function of the other communication component () and the function of the data bus ().

The invention relates to a control System () for a motor vehicle (), comprising a central vehicle Controller () for Controlling vehicle functions () and a plurality of driver assistance Systems (). The driver assistance Systems () are set up to transmit a task key describing the particular assistance function thereof to the vehicle Controller () and to transmit a security key assigned to the particular assistance function to the vehicle Controller (). The central vehicle Controller () is set up to identify a particular task of the driver assistance Systems () on the basis of the transmitted task keys, to carry out a security check by virtue of the vehicle Controller () checking, on the basis of the security keys transmitted in each case for the respectively identified tasks, whether the particular security key complies with at least one security level assigned to the particular task, and, if the security check was successful, to control the vehicle functions () according to respective control commands transmitted by the driver assistance System () in Order to perform the respective assistance functions. The invention also comprises a method for operating such a control System () and a motor vehicle () having such a control System ().

A method for improving the ride comfort of a transportation vehicle including planning a first driving route by a navigation system; automatically detecting at least one road parameter of the first driving route by a sensor system of the transportation vehicle; automatically evaluating the first driving route in view of the ride comfort of the first driving route by taking into account the road parameter; and in response thereto using the first driving route or planning an alternative driving route.

A method for determining an alternative trajectory for an autonomously-driven transportation vehicle wherein an alternative trajectory for the transportation vehicle is calculated by a control device in response to an obstacle being detected by a transportation vehicle sensor device, which trajectory replaces at least one portion of an original trajectory of the transportation vehicle so the trajectory has a minimum total disturbance of at least one disturbance summand, consisting of a respective weighting factor and one disturbance value.

A method for controlling self-braking of a motor vehicle wherein a collision detection device predicts an imminent collision and determines for the self-braking a TTB braking time at which the self-braking is to start, and a brake system is operated in a standby state in which the brake system reacts to a braking request of the collision detection device with activation of wheel brakes of the motor vehicle, wherein the brake system requires a dead travel time to generate for the first time a braking torque by the wheel brakes starting from the standby state, for the self-braking. The method provides that a time period value of the dead travel time is made available in the motor vehicle, and the wheel brakes are activated at a starting time when the imminent collision is detected.

A method for controlling a deceleration device of a motor vehicle, wherein a control apparatus receives a request signal from a vehicle component for vehicle deceleration. Protection against mistriggering of the deceleration device is provided. Also provided is an integrity level of the vehicle component to be ascertained, a time profile for a deceleration performance of the deceleration device obtained during a braking process to be ascertained, for different times, a respective current minimum integrity level that is at least necessary for the time profile ascertained hitherto to be ascertained, and performance limiting to be performed for the request signal if the current minimum integrity level is higher than the integrity level of the vehicle component.
