Patent number: 10894460Abstract: An occupant detection system may detect a state of an occupant in a vehicle compartment. The occupant detection system may photograph the vehicle compartment and generate an image. The occupant detection system may change an attitude in order to change a position of an imaging region within the vehicle compartment. The occupant detection system may estimate the attitude based on information included in the image and control an operation based on the estimated attitude. The sensor may be provided by an infrared temperature sensor. The image may be provided by a thermal image showing a temperature distribution of the vehicle compartment.

Patent number: 10434840Abstract: A control system for a radiant heater device includes a radiant heater device, a heater ECU that controls an energization and a deenergization of a heat generation unit, and an integrated ECU that transmits an operation prohibition command for prohibiting the energization of the heat generation unit and an operation permission command for permitting the energization of the heat generation unit to the heater ECU. The integrated ECU transmits the operation prohibition command when receiving a collision signal indicative of a vehicle collision or a prediction of the vehicle collision, and transmits the operation permission command when not receiving the collision signal. The heater ECU performs the deenergization control when a non-reception state in which the operation permission command is not received from the integrated ECU is continued for a predetermined time or more. As a result, the energization can be interrupted before an occupant is adversely affected.Type: GrantFiled: February 3, 2015Date of Patent: October 8, 2019Assignee: DENSO CORPORATIONInventors: Kimitake Ishikawa, Hideaki Kako, Akira Oga, Hiroshi Takeda

Patent number: 10214125Abstract: An air-circulation promotion apparatus for a vehicle includes a driver's seat and a front passenger seat provided in the vehicle, and a face outlet port of a vehicle air conditioner disposed in front of those seats. A seat outlet port that blows a sucked air from a side surface of a seat back of the seat toward a rear area of the vehicle is disposed in the seat. An air present between the face outlet port and the seat flows rearward of the seat by aid of wind blown out of the seat outlet port. This makes it possible to circulate a comfortable air rearward of the seat to create a vehicle interior environment having no air retention. A circulation fan is provided in the seat and can be integrated with a seat ventilation system or a seat air conditioner.Type: GrantFiled: September 25, 2013Date of Patent: February 26, 2019Assignee: DENSO CORPORATIONInventors: Hiroyuki Sakane, Yasuhiko Niimi, Yuuji Yamanaka, Akira Oga
