This paper proposes a low-price but oblique method for occupancy detection and occupant counting goal in present and future automotive programs. It could possibly serve as both a method to determine the number of occupants riding inside a car or a approach to complement the other gadgets in determining the occupancy. The proposed method is beneficial for numerous mobility functions together with automotive rental, fleet management, taxi, automotive sharing, occupancy in autonomous vehicles, and so forth. It makes use of current on-board motion sensor measurements, resembling those used in the car stability control function, along with door open and closed status. The vehicle’s movement signature in response to an occupant’s boarding and alighting is first extracted from the motion sensors that measure the responses of the automobile body. Then the weights of the occupants are estimated by fitting the car responses with a transient car dynamics model. This two stage method is further used to determine what number of occupants are staying in the automobile. The effectiveness of the proposed approaches has been verified in vehicle checks by a wide range of occupancy configurations.
