This paper proposes a low-value however indirect method for occupancy detection and occupant counting goal in present and future automotive programs. It could possibly function either a way to find out the number of occupants riding inside a automotive or a strategy to complement the other gadgets in determining the occupancy. The proposed technique is useful for various mobility applications together with automobile rental, fleet administration, taxi, car sharing, occupancy in autonomous automobiles, and so on. It utilizes existing on-board motion sensor measurements, similar to those used within the automobile stability control function, along with door open and closed status. 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 body. Then the weights of the occupants are estimated by fitting the vehicle responses with a transient automobile dynamics mannequin. This two stage approach is further used to determine how many occupants are staying within the car. The effectiveness of the proposed approaches has been verified in car tests via a wide range of occupancy configurations.
