An alighting assistance device D of the present disclosure may be a device moving a driver seat rearward in a case where a determination may be made that an occupant seated on the driver seat of a vehicle alights. The device may include a height changer which changes a height of a steering wheel, a sitting height acquirer which acquires a sitting height of the occupant, and a steering wheel controlleras one example of a height controller which controls the height changer such that the height of the steering wheel becomes lower as the sitting height acquired by the sitting height acquirer may be higher in the case where a determination is made that the occupant alights.

Alighting assistance device and method

An alighting assistance device D of the present disclosure may be a device moving a driver seat rearward in a case where a determination is made that an occupant seated on the driver seat of a vehicle alights. The device may include a reclining mechanism as one example of an angle changer which changes an angle of a seat back of the driver seat with respect to a horizontal plane, a sitting height acquirer which acquires a sitting height of the occupant, and a seat controller as one example of an angle controller which controls the angle changer such that the angle of the seat back becomes closer to be perpendicular as the sitting height acquired by the sitting height acquirer is higher in the case where a determination is made that the occupant alights.

The present invention relates to an on-vehicle emergency notification device for performing a notification to an external emergency call center, in the event of an emergency. The on-vehicle emergency notification device is configured to allow a vehicle body number (VIN) and an emergency notification phone number (CIM number) to be registered therein in the form of a set, so as to enable the notification to the emergency call center, wherein the on-vehicle emergency notification device is configured such that: during execution of a factory mode for performing the registration of the vehicle body number and the emergency notification phone number, rewriting of the vehicle body number is permitted; and, after the registration of the vehicle body number and the emergency notification phone number is completed and then the factory mode is shifted to a market mode, the rewriting of the vehicle body number is prohibited.

The seat heater control device is provided for a vehicle including a vehicle body, a vehicle seat and a seat heater. The seat heater control device includes: an electrostatic sensor provided in the vehicle seat and configured to measure capacitance between the electrostatic sensor and the vehicle body; and a controller configured to control an operation and/or an operational temperature of the seat heater, based on a measured value of the electrostatic sensor. The controller is configured to cause the seat heater to operate at a relative higher temperature when the measured value of the electrostatic sensor is higher than a first threshold and lower than a second threshold. The controller is configured to cause the seat heater to operate at a relative lower temperature when the measured value of the electrostatic sensor is higher than the second threshold.

The object is to provide an occupant detection device that can accurately detect whether there is a passenger, even when a personal computer, a tablet terminal, a smartphone or the like is placed on a vehicle seat. The occupant detection device is provided for a vehicle including a vehicle body, a vehicle seat and an in-vehicle battery. The occupant detection device includes: an electrostatic sensor provided in the seat and configured to measure capacitance between the sensor and the vehicle body; an interrupting unit configured to interrupt a function of the in-vehicle battery; a controller configured to temporarily activate the interrupting unit when a measured value of the electrostatic sensor is higher than a predetermined threshold; and a judgement unit configured to judge that there is a passenger when the measured value of the electrostatic sensor is higher than the predetermined threshold even while the interrupting unit is activated.
