Abstract: A method for the longitudinal control of a vehicle according to a target trajectory specifying a series of target positions to be adopted by the vehicle over time. Based on an actual status of the vehicle, a control acceleration is determined for the purpose of trajectory control, by which the vehicle is to be accelerated according to specifications of the target trajectory. Based on an actual speed of the vehicle and a predefined maximum speed which should not be exceeded when travelling the target trajectory, a control acceleration for the purpose of speed control is determined, by which the vehicle is to be accelerated in order to travel at the maximum speed. Both control accelerations are supplied to an arbiter which determines a resulting control acceleration from same, wherein the vehicle is accelerated according to the resulting control acceleration. A device for the longitudinal control of the vehicle is provided.

Abstract: A method and device for longitudinal control of a vehicle as a function of a target trajectory, which specifies a series of target positions to be assumed by the vehicle over time. A controller actuating acceleration for trajectory control is determined based on an actual state of the vehicle. When the vehicle is following the target trajectory, a curvature of the target trajectory at a current position of the vehicle is determined from a local course of the target trajectory. Furthermore, when the vehicle is following the target trajectory, a longitudinal acceleration resulting from the target trajectory is determined as the current trajectory acceleration at the current position of the vehicle and the controller actuating acceleration is limited to a value that corresponds at most to a sum of the current trajectory acceleration and the acceleration offset. The vehicle is accelerated in accordance with the limited controller actuating acceleration.
