Abstract
A computer includes a processor and a memory, the memory storing instructions executable by the processor to receive radar data from an ultrawideband radar in a passenger compartment of a vehicle, determine a starting-time for a time-window based on a second derivative of the radar data, identify a motion inside the passenger compartment based on the radar data received during the time-window, and actuate a component of the vehicle based on the identification of the motion.
Claims19
A computer comprising a processor and a memory, the memory storing instructions executable by the processor to:
- receive radar data from an ultrawideband radar in a passenger compartment of a vehicle;
- set a first starting-time for a first time-window in real time based on a second derivative of fast time in the radar data with respect to slow time in the radar data;
- identify a motion inside the passenger compartment based on the radar data received during the first time-window and based on the radar data received during a second time-window, the second time-window starting at an ending time of the first time-window;
- and
- actuate a component of the vehicle based on the identification of the motion.
