It utilizes current on-board motion sensor measurements, corresponding to those used in the automobile stability control function, together with door open and closed standing. The vehicle’s motion signature in response to an occupant’s boarding and alighting is first extracted from the movement sensors that measure the responses of the automobile physique. Then the weights of the occupants are estimated by fitting the vehicle responses with a transient automobile dynamics mannequin. This two stage approach is additional used to find out what number of occupants are staying in the car.
