An Oblique Occupancy Detection And Occupant Counting System Utilizing Motion Sensors
This paper proposes a low-cost however oblique technique for occupancy detection and occupant counting objective in present and future automotive programs. It may well serve as both a manner to find out the variety of occupants riding inside a automobile or a option to complement the opposite devices in figuring out the occupancy. The proposed technique is beneficial for various mobility purposes together with automobile rental, fleet administration, taxi, automotive sharing, occupancy in autonomous autos, and so forth. It utilizes present on-board movement sensor measurements, corresponding to those used within the car 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 motion sensors that measure the responses of the car physique. Then the weights of the occupants are estimated by fitting the car responses with a transient vehicle dynamics model. This two stage strategy is further used to find out how many occupants are staying within the car. The effectiveness of the proposed approaches has been verified in automobile assessments by means of quite a lot of occupancy configurations.
