A longitudinal control system is provided for a motor vehicle equipped with a sensor system for detecting a traffic event lying ahead, in particular in order to locate vehicles traveling ahead, and a control unit for automatically controlling the speed or the acceleration of the motor vehicle to a standstill on the basis of the traffic event lying ahead. An automatic drive-off is allowed without a driver confirmation within a specified time interval after reaching the standstill, and after the time interval has expired, an automatic start-up is allowed after a start-up confirmation is triggered by the driver. A start-up confirmation is triggered if a contacted state of the steering wheel is detected starting from a non-contacted state of the steering wheel.

Longitudinal control system for a motor vehicle

A method for controlling a trajectory planning process of an ego-vehicle includes the following steps: determining a longitudinal movement of the ego-vehicle, the longitudinal movement including a speed of the ego-vehicle; determining a longitudinal movement of an object, the longitudinal movement including a speed of the object; calculating a target trajectory of the object on the basis of a predicted trajectory of the object; calculating an end time of a maneuvering process of the ego-vehicle, the end time of the maneuvering process being a point in time at which a differential speed between the ego-vehicle and the object is dissipated; calculating a distance between a position of the ego-vehicle and the position of a third-party vehicle with respect to the calculated target trajectory at the calculated end time of the maneuvering process of the ego vehicle; and if the calculated distance of the ego-vehicle at the calculated end time of the maneuvering process equals a specified threshold or falls below a specified threshold: setting the specified speed of the object as the target speed of the ego-vehicle and transmitting the target speed to the trajectory planning process in order to calculate a following trajectory for the ego-vehicle.
