Abstract: A method is disclosed for predicting traffic participant behavior. The method includes obtaining a first kinematic state distribution of a traffic participant at a first time. Second kinematic state distributions of the traffic participant are projected at a second time which is a first time span into the future. A distribution of trajectories are defined, wherein each trajectory links a kinematic state of the first kinematic state distribution to a kinematic state of the second kinematic state distribution. A third kinematic state distribution is obtained of the traffic participant at a third time which is a second time span later than the first time and shorter than the first time span. Compatibilities between the third kinematic state distribution and a distribution of kinematic states resulting from evaluating each trajectory of the distribution of trajectories at the third time are determined and probabilities assigned to the trajectories using the determined compatibilities.

Abstract: In a linear drive device, a movable member is driven using a guide shaft and a lead screw supported by a bracket. Since a nut mechanism, which with the lead screw configures a feed screw mechanism, is provided with a first spring between two nuts, it is possible to limit rattling of the nuts with respect to the lead screw.

A check is carried out to determine whether the source-gate voltage reaches an upper threshold value when the test mode is being carried out. An error signal is output when the first target value and/or the upper threshold value is/are not reached.
