This paper proposes a low-price however indirect method for occupancy detection and occupant counting goal in current and future automotive methods. It may possibly serve as both a way to determine the number of occupants riding inside a automobile or a strategy to complement the other units in determining the occupancy. The proposed technique is helpful for various mobility applications including car rental, fleet management, taxi, car sharing, occupancy in autonomous autos, and many others. It makes use of present on-board movement sensor measurements, such as those used in the automobile stability control function, together with door open and closed standing. 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 automobile responses with a transient car dynamics model. This two stage approach is further used to find out what number of occupants are staying within the car. The effectiveness of the proposed approaches has been verified in vehicle checks via a wide range of occupancy configurations.
