This paper proposes a low-cost however oblique method for occupancy detection and occupant counting function in current and future automotive methods. It can serve as both a means to determine the number of occupants riding inside a automotive or a way to complement the other devices in determining the occupancy. The proposed technique is helpful for varied mobility applications together with car rental, fleet management, taxi, automotive sharing, occupancy in autonomous autos, etc. It makes use of present on-board movement sensor measurements, resembling those used in the car stability management operate, together 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 car body. Then the weights of the occupants are estimated by fitting the car responses with a transient car dynamics model. This two stage approach is additional used to find out how many occupants are staying within the car. The effectiveness of the proposed approaches has been verified in car checks by way of a variety of occupancy configurations.
