An Indirect Occupancy Detection And Occupant Counting System Utilizing Movement Sensors
This paper proposes a low-cost but indirect methodology for occupancy detection and occupant counting goal in current and future automotive systems. It could possibly serve as either a manner to find out the number of occupants riding inside a automobile or a approach to complement the opposite units in figuring out the occupancy. The proposed method is beneficial for varied mobility functions together with automobile rental, fleet administration, taxi, automotive sharing, occupancy in autonomous autos, etc. It utilizes existing on-board movement sensor measurements, corresponding to these used in the automobile stability control operate, 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 movement 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 vehicle dynamics mannequin. This two stage strategy is further used to determine how many occupants are staying within the automobile. The effectiveness of the proposed approaches has been verified in automobile assessments via a variety of occupancy configurations.
