A first data acquiring unit to acquire first data acquired by a first sensor, a second data acquiring unit to acquire second data acquired by a second sensor installed above a seat in a cabin, a front-seat occupant position estimating unit to estimate a position of an occupant on a basis of the first data acquired by the first data acquiring unit, a detection range determining unit to determine a detection range of the second sensor on a basis of the position of the front-seat occupant estimated by the front-seat occupant position estimating unit, and a rear-seat occupant detecting unit to detect a rear-seat occupant on a basis of the second data acquired by the second data acquiring unit and the detection range of the second sensor determined by the detection range determining unit are provided.

System and method for obtaining and recording information about cargo includes a frame defining a cargo-receivable compartment, a position determining system at least partly on the frame and that allows for determination of position of the frame, an identification system on the frame that obtains information about cargo when present in the compartment, a memory component that receives and records information about position and movement of the frame, and the obtained information about cargo when present in the compartment in association with a unique identification of the frame, and a communications system on the frame to enable communication of information to and from the memory component.

A method of operating a radar sensor system for determining a number of passengers in a vehicle passenger compartment. The radar sensor system includes at least one radar transmitting antenna and at least one radar receiving antenna and an evaluation and control unit for evaluating Doppler information from the received radar waves. The method includes: transmitting radar waves towards the vehicle passenger compartment; receiving radar waves reflected by a passenger or by passengers being present in the vehicle passenger compartment; generating received radar signals from the received radar waves; mathematically decomposing the received radar signals into a plurality of received signal components; providing values of the received signal components regarding a characteristic parameter to a classifier trained with a plurality of scenarios; identifying one of trained scenarios, based on the provided values; and generating an output signal indicative of the identified scenario.

Vehicle occupant monitoring systems and methods detect that an outer handle of the vehicle is used to open a door, and determine a key fob state of the vehicle. On condition that the key fob state of the vehicle is undetected, at least one type of alert is transmitted to a mobile device associated with the vehicle.

A method and system for detecting a presence of at least one living being inside a cabin of a vehicle by radio signals. At least one transmission signal is transmitted from at least one transmission unit positioned at a transmission unit position inside the cabin towards a surveillance area of an interior of the cabin. Receiving responding signals from the surveillance area caused by a reflection of the transmission signal in the surveillance area with at least two receiving units each positioned at a receiving unit position inside the cabin, whereat all of the receiving unit positions are placed apart from each other and the responding signals are being received by anyone of the receiving units. Evaluating of the responding signals and detecting the presence of the living being in the surveillance area and triggering an action of at least one actuator of the vehicle.

An occupant detection system includes a transmitter provided adjacent to a first side face of a vehicle before a predetermined seat and successively transmitting a radio wave over a range covering a seat door located on a second side face of the vehicle and in a same row as the predetermined seat, a receiver provided adjacent to the second side face behind the predetermined seat and receiving the radio wave transmitted from the transmitter, and an occupant detection device including a reception intensity acquirer, an occupant detector, an opening and closing detector. The reception intensity acquirer successively acquires a reception intensity of a radio wave successively received by the receiver. The occupant detector detects an occupant in the vehicle according to the reception intensity of the radio wave received by the receiver while the opening and closing detector detects that the seat door is open.

Vehicle occupant monitoring systems and methods detect that an outer handle of the vehicle is used to open a door, and determine a key fob state of the vehicle. On condition that the key fob state of the vehicle is undetected, at least one type of alert is transmitted to a mobile device associated with the vehicle.
