An Indirect Occupancy Detection And Occupant Counting System Utilizing Motion Sensors

Jump to: navigation, search

This paper proposes a low-value but oblique methodology for occupancy detection and occupant counting goal in current and future automotive systems. It may well serve as both a way to find out the variety of occupants riding inside a automobile or a approach to complement the opposite devices in figuring out the occupancy. The proposed technique is beneficial for numerous mobility purposes including automotive rental, fleet administration, taxi, car sharing, occupancy in autonomous autos, and so on. It utilizes present on-board movement sensor measurements, corresponding to these used within the automobile stability control function, along with door open and closed standing. 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 car body. Then the weights of the occupants are estimated by fitting the vehicle responses with a transient automobile dynamics mannequin. This two stage method is additional used to determine how many occupants are staying within the car. The effectiveness of the proposed approaches has been verified in vehicle assessments by way of a variety of occupancy configurations.
