1. A system comprising:
a sensor system configured within a cabin of a vehicle and configured to generate sensor data indicative of a movement of a child seat sitting on a seat of the vehicle, wherein the sensor data includes at least one of elevation data, resolution data, range data, and doppler data;
a processor of the vehicle and communicatively coupled to the sensor system, the processor configured to determine, from the sensor data, a baseline position of the child seat sitting on the seat of the vehicle, determine, from the sensor data, a real time displacement of the child seat from the baseline position in response to a vehicle speed being greater than a threshold speed and a vehicle dynamic information indicative of a vehicle maneuver, and selectively generate notification data based on the real time displacement exceeding a threshold displacement; and
a user interface to display a visual notification to a vehicle occupant in response to the notification data.
