An emergency notification device () for notifying an emergency notification center () of emergency information b from the vehicle () in case of vehicle emergency, comprising: a wireless communication part () for performing wireless communication with the emergency notification center (); a control part () for controlling the wireless communication part () to perform wireless communication with the emergency notification center () in case of vehicle emergency; and an in-vehicle communication part () for performing communication with a communication terminal () in the vehicle; wherein the control part () is configured to, in a wireless communication disabled state in case of vehicle emergency, communicate with the communication terminal () in the vehicle via the in-vehicle communication part to cause the communication terminal () to transmit the emergency information b to a predetermined emergency contact destination.

Emergency notification device and emergency notification system

An emergency notification device () for notifying of emergency information, comprising: a voice input/output part () for performing input/output of voice in the vehicle; a wireless communication part () for performing wireless communication; a control part () controlling the wireless communication part and the voice input/output part to perform voice conversation by wireless communication in case of vehicle emergency; and a vehicle communication part () for performing communication with a communication terminal () in the vehicle; wherein the control part is configured to, in a voice input/output disabled state, communicate with the communication terminal via the vehicle communication part to perform input/output of voice via the communication terminal in the vehicle and perform voice conversation by wireless communication with the emergency notification center via the wireless communication part.

An offset distance of an obstacle from a traveling-path center line of a vehicle at the time the obstacle is detected is calculated, and then this offset distance of the obstacle from the traveling-path center line of the vehicle is corrected based on a turning radius of the traveling vehicle detected at the time a specified period of time has lapsed. Thereby, even in a case where the vehicle travels on a road with a curve that changes a radius of curvature of the traveling-path center line (turning radius of the traveling vehicle) quickly during the specified period of traveling time, the above-described offset distance can be properly corrected based on an updated turning radius of the traveling vehicle. Thus, a relative position of the obstacle with respect to the vehicle can be predicted accurately.

Obstacle detecting control device of vehicle

Disclosed is a BSD system for vehicle provided with a blind spot detection module which includes obstacle in blind spot detection unit for detecting an obstacle existing in a blind spot around the rear side of a self vehicle and an obstacle indicator disposed on a side mirror of the self vehicle and adapted to display at least one of information for the existence of an obstacle in the blind spot, for a distance between the obstacle and the self vehicle, and for a relative speed of the obstacle to the self vehicle, the blind-spot detection system for vehicle. This system is provided with a unit for detecting that the blind spot detection module is in an abnormal operation state and a unit disposed on the side mirror having the obstacle indicator and adapted to visually indicate an abnormality of the blind spot detection module detected by the abnormality detection unit.

Blind-spot detection system for vehicle

The present invention has as its object to provide a vehicle passenger detection device that is able to prevent erroneous determinations arising from mechanical hysteresis. The present invention provides a vehicle passenger detection device comprising: weight measurement means, provided with a weight sensor disposed between a seat and floor of a vehicle, that measures the load applied to the seat; fluctuation amplitude detection means that detects the amplitude of fluctuation in values measured by the weight measurement means; correction means that applies a negative correction to the value measured by the weight measurement means when the fluctuation amplitude is smaller than a stipulated value; and passenger presence determination means that determines the presence of a passenger upon the seat by comparing the value measured by the weight measurement means against a stipulated threshold value.

Vehicle passenger detection device

A seat cushion for a vehicle seat unit comprising a cushioning pad upholstered with a seat covering and a flexible but inelastic planar film with an electrically conductive element buried therein that is disposed between the cushioning pad and the seat covering. The cushioning pad has tuck-in grooves in which the seat covering is locally retained. The planar film is thickened at locations where the planar film transverses the tuck-in grooves for reinforcement.

Seat cushion for vehicle seat unit

A seat belt system which does not interfere with the ingress and egress of rear seat passengers, and can detect the presence of an occupant without being influenced by the seat belt tension to provide the accurate weight detection. In one embodiment, the seat belt system comprises a retractor disposed in the rear door, an anchor of the seat belt webbing, and a rail member that allows the anchor of the seat belt webbing to slide in the vehicular longitudinal direction. The front end of the rail member is attached substantially on the seat side above a weight detecting device. The weight detecting device is disposed between the front seat and the floor panel, while the buckle capable of engaging the tongue of the seat belt webbing is disposed on the seat above the weight detecting device.
