Abstract: A method for classifying at least one object in the surroundings of a vehicle using an ultrasonic sensor system. The method includes: emitting ultrasonic signals at a plurality of successive time points using the ultrasonic sensor system; and receiving ultrasonic echo signals reflected on the one or more objects in the surroundings of the vehicle, using the ultrasonic sensor system; wherein one or more objects in the surroundings are ascertained as a function of the received ultrasonic echo signals, and wherein it is determined as a function of the received ultrasonic echo signals whether the respective object is classified as dynamic, in particular as a pedestrian. A controller for operating an ultrasonic sensor system, an ultrasonic sensor system, and a vehicle including such an ultrasonic sensor system are also described.

Abstract: A system for checking an inertial measurement unit of a vehicle, in particular a land vehicle, during driving includes the inertial measurement unit having: a first acceleration sensor configured to measure a translational acceleration along a first sensor axis and/or a first rate-of-rotation sensor configured to measure a rate of rotation about the first sensor axis and also a second acceleration sensor configured to measure a translational acceleration along a second sensor axis and/or a second rate-of-rotation sensor configured to measure a rate of rotation about the second sensor axis. A sensing device senses a movement of the vehicle in a first vehicle direction and/or about the first vehicle direction. Both the first sensor axis and the second sensor axis are tilted with respect to the first vehicle direction.
