In order to detect the amount of radiation received by or the temperature of air in the vicinity of each of body parts of an occupant in a vehicle, a radiation information calculating device includes: an acquisition unit that acquires member temperature information that reflects temperatures of members exposed to a cabin of a vehicle; a calculation unit configured to calculate plural radiation information corresponding to each of body parts of an occupant in the cabin based on the member temperature information acquired by the acquisition unit; and an output unit that outputs the plural radiation information calculated by the calculation unit. The radiation information represents an amount of radiation received by a corresponding body part of the occupant.

Radiation information calculating device and temperature information calculating device

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. The occupant detection system may store a correspondence relationship between a position of a specific temperature boundary included in the thermal image and the attitude. The occupant detection system may estimate the attitude based on the correspondence relationship.

Occupant detection system

An occupant detection system includes a state detection unit that detects a state of an object, a detection position changing unit that changes a position of a detection region, the detection region being a region in which state is detected by the state detection unit, and a controller that controls an operation of the detection position changing unit. In this occupant detection system, a position of the detection region is set to a predetermined initial position during a period of time from when a start switch provided in the vehicle is turned off until when the start switch is turned on.

A vehicular air conditioner includes a temperature detection unit that detects a surface temperature of an object based on radiation from the object, a swing mechanism unit that causes the temperature detection unit to swing, thereby changing a location of a detection region, the detection region being a region in which surface temperature is detected by the temperature detection unit, and a controller that controls an operation of the swing mechanism unit. The controller changes the operation of the swing mechanism unit based on a magnitude of a thermal load in a passenger compartment.

Vehicular air conditioner

A vehicular air-conditioner includes: a wind changing unit that changes at least one of a wind volume and a wind direction of air-conditioned wind, a temperature detection unit that detects a surface temperature of an object based on radiation from the object, a detection position changing unit that changes a position of a detection target region that is a region in which the surface temperature is to be detected by the temperature detection unit, and a control unit that controls each operation of the wind changing unit and the detection position changing unit. The control unit controls at least one of the operation of the wind changing unit and the operation of the detection position changing unit to suppress changes in the wind volume of the air-conditioned wind in the detection target region when a portion of the surface of an occupant is in the detection target region.

Vehicular air-conditioner

A radiant heater device includes: a heater main body having a heating portion that generates heat by being supplied with electric power to radiate radiation heat due to the heat supplied from the heating portion; an output control unit that controls an output of the heating portion; and a maximum output determination unit that determines an upper limit of the output of the heating portion depending on a heat load around the heater main body. The output control unit controls the output of the heating portion depending on the heat load not to exceed the upper limit of the output determined by the maximum output determination unit.

Radiant heater device

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.

In an air amount control for controlling an air amount to be blown into a vehicle compartment, a water temperature control map in which the air amount is set based on a water temperature of cooling water for the vehicle is stored, and the air amount is determined based on control characteristics of the water temperature control map. The water temperature control map is learned and changed based on a set air amount, and the air amount to be blown into the vehicle compartment is determined based on the learned water temperature control map in a case where the set air amount is changed by a passenger and the water temperature is in a predetermined range.

In a vehicle air conditioner, when a passenger set temperature of a vehicle compartment is changed through an operation portion by a passenger, a storage portion updates a value of a control set temperature corresponding to a predetermined point of a detection area at a time of the changing operation to a value of the changed passenger set temperature, and stores therein the value of the updated temperature. Furthermore, when the detection point is not any one of the predetermined points, a control portion interpolates and calculates a control set temperature corresponding to the detection point from the control set temperature stored in the predetermined point of the detection area and the control set temperature stored in the predetermined point of a surrounding area around the detection area, and then controls the air-conditioning state in the vehicle compartment based on the interpolated and calculated control set temperature.
