An Indirect Occupancy Detection And Occupant Counting System Utilizing Movement Sensors
This paper proposes a low-value however indirect method for occupancy detection and occupant counting goal in present and future automotive programs. It may possibly serve as either a approach to find out the variety of occupants riding inside a automotive or a option to complement the other gadgets in determining the occupancy. The proposed method is useful for numerous mobility applications together with automobile rental, fleet management, taxi, automotive sharing, occupancy in autonomous vehicles, etc. It utilizes existing on-board motion sensor measurements, akin to those used within the automobile stability management perform, 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 movement sensors that measure the responses of the automobile 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 additional used to determine how many occupants are staying within the automotive. The effectiveness of the proposed approaches has been verified in vehicle checks via a wide range of occupancy configurations.
