Detailed ways

Hereinafter, embodiments of the vehicle control device according to the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing a functional configuration of a vehicle control system 10 of the present embodiment.

The vehicle 1 on which the vehicle control system 10 of the present embodiment is mounted is, for example, a two-wheeled, three-wheeled, four-wheeled, or other automobile. The vehicle 1 includes an automobile powered by an internal combustion engine such as a diesel engine or a gasoline engine, an electric vehicle powered by an electric motor, a hybrid electric vehicle having both an internal combustion engine and an electric motor, and the like. Electric vehicles are driven, for example, using electric power discharged from batteries such as secondary batteries, hydrogen fuel cells, metal fuel cells, and ethanol fuel cells.

As shown in FIG. 1 , the vehicle control system 10 includes a raindrop sensor 11 , a temperature sensor 12 , a driver monitoring camera 13 , an air conditioner 14 and a control device 15 .

The raindrop sensor 11 is provided at the front, side or rear of the vehicle 1 . The raindrop sensor 11 is a digital camera using a solid-state imaging element such as a Charge Coupled Device (CCD) or a Complementary Metal Oxide Semiconductor (CMOS), for example.

FIG. 2A is a diagram illustrating the situation when the raindrop sensor 11 acquires raindrop data. As shown in FIG. 2A , the raindrop sensor 11 acquires raindrop data outside the vehicle 1 by capturing images including raindrops adhering to an area A (for example, a windshield and a hood) outside the vehicle 1 . The raindrop sensor 11 outputs the acquired raindrop data to the control device 15 .

In addition, the raindrop sensor 11 can also acquire raindrop data by detecting raindrops on the windshield of the vehicle 1 , for example. In this case, the raindrop sensor 11 includes a light-emitting element such as a light-emitting diode that emits light (infrared rays) from the inside of the vehicle 1 toward the windshield, and a light-receiving element such as a photodiode that receives reflected light of the light emitted from the light-emitting element.

The temperature sensor 12 is installed in the vehicle 1 and acquires temperature distribution data on the body surface of an occupant in the vehicle 1 . The temperature sensor 12 outputs the acquired temperature distribution data to the control device 15 . The temperature sensor 12 is, for example, an infrared thermal imaging camera. The infrared thermal imaging camera images infrared radiation from an object, converts it into temperature, and acquires temperature distribution data on the body surface of the occupant in the vehicle 1 .

FIG. 2B is a diagram illustrating an example of temperature distribution data acquired by the temperature sensor 12 . As shown in FIG. 2B , the temperature sensor 12 acquires temperature distribution data B1. The obtained temperature distribution data B1 is graded using the index B2. The index B2 shown in FIG. 2B is composed of temperature grade 1 to temperature grade 5. The smaller the temperature grade is, the lower the temperature is, and the larger the temperature grade is, the higher the temperature is. In this way, the infrared thermal imaging camera can visualize the temperature distribution using colors.

The driver monitoring camera 13 is installed in the vehicle 1 and acquires captured images including the occupants of the vehicle 1 . The driver monitoring camera 13 acquires image data of the occupant's clothes or hair by capturing an image including the occupant of the vehicle 1 . The driver monitoring camera 13 outputs captured image data to the control device 15 . Furthermore, in the present embodiment, the clothes of the occupant include items worn by the occupant such as clothes, socks, shoes, hats, and the like.

The driver monitoring camera 13 is composed of a digital camera using a solid-state imaging element such as a Charge Coupled Device (CCD) or a Complementary Metal Oxide Semiconductor (CMOS), and its type is not particularly limited.

FIG. 2C is a diagram showing the situation when the driver monitoring camera 13 acquires image data. As shown in FIG. 2C , the driver monitoring camera 13 acquires a captured image including the occupant D of the vehicle 1 . In the example of FIG. 2C , three parts of the occupant D, namely the hair part C1 , the clothes part C2 and the clothes part C3 , are wet from the rain.

The air conditioner 14 is also called an air conditioner, and adjusts the environment in the vehicle 1 by adjusting the state of the air in the vehicle 1 . The operation of the air conditioner 14 is controlled by an air conditioner control unit 154 described later. The air conditioner 14 may also include a heater, and the heater may be provided separately from the air conditioner 14 .

The control device 15 includes a plurality of electronic control units (Electronic Control Unit, ECU) communicably connected via an in-vehicle network. Each ECU functions as a computer including a processor such as a central processing unit (Central Processing Unit, CPU), a storage device such as a semiconductor memory, an interface with an external device, and the like. The memory device stores programs executed by the processor, data used in processing by the processor, and the like. Each ECU may also have multiple processors, storage devices, interfaces, and the like.

The control device 15 includes a rainfall state determination unit 151 , a temperature difference determination unit 152 , a humidity state determination unit 153 , and an air-conditioning control unit 154 .

The rain state determination unit 151 determines whether or not the exterior of the vehicle 1 is in a rain state based on the raindrop data output from the raindrop sensor 11 . Specifically, when the raindrop data output from the raindrop sensor 11 indicates an amount of rain equal to or greater than a fixed amount, the rain state determination unit 151 determines that the outside of the vehicle 1 is in a rain state. For example, when the image including raindrops as the raindrop data includes an image showing a fixed amount of rain or more, the rain state determination unit 151 determines that the outside of the vehicle 1 is in a rain state.

The temperature difference determination unit 152 determines whether or not the temperature of the occupant's body surface is equal to or higher than a predetermined threshold value based on the temperature distribution data output from the temperature sensor 12 . Specifically, the temperature difference determination unit 152 obtains the temperature level of each part of the occupant's body surface based on the temperature distribution data output from the temperature sensor 12, and determines whether the temperature level is equal to or greater than a predetermined threshold value T1.

For example, in FIG. 2B , the temperature difference determination unit 152 sets a predetermined threshold T1 to temperature level 2, and determines whether the temperature level of each part of the occupant's body surface is temperature level 2 or higher.

The wet state determination unit 153 determines whether the occupant's clothes or hair are in a wet state based on the image data output from the driver monitoring camera 13 .

For example, the wet state determination unit 153 calculates the average value V1 of the brightness of the clothes of the occupant in the first area and the average value V2 of the brightness of the clothes of the occupant in the second area from the image data. Then, when the difference between the average value V1 of the luminance and the average value V2 of the luminance is equal to or greater than the predetermined threshold value T2, the wet state determination unit 153 determines that the clothes of the occupant are in a wet state.

Similarly, the wet state determination unit 153 calculates the average value V3 of the brightness of the hair of the occupant in the first area and the average value V4 of the brightness of the hair of the occupant in the second area from the image data. Then, when the difference between the average value V3 of the luminance and the average value V4 of the luminance is equal to or greater than the predetermined threshold value T3, the wet state determination unit 153 determines that the occupant's hair is in a wet state.

The air conditioner control unit 154 controls the air conditioner 14 of the vehicle 1 based on raindrop data, body surface temperature distribution data, and image data of the occupant's clothes or hair. Specifically, the air conditioner control unit 154 automatically activates the air conditioner 14 when it is raining outside the vehicle 1 , the occupant's body surface temperature is equal to or higher than a predetermined threshold, and the occupant's clothes or hair are wet.

FIG. 3 is a schematic diagram illustrating the flow of air when the air conditioner 14 is automatically activated. As shown in FIG. 3 , the air conditioner control unit 154 automatically activates the air conditioner 14 , whereby the vehicle control system 10 supplies the driver D with the air flow E1 and the air flow E2 . Thus, the driver D can dry his hair and clothes with the air flow E1 and dry his shoes with the air flow E2.

In addition, the air-conditioning control unit 154 controls the direction of the air discharged from the air-conditioning apparatus 14 toward the site determined to be in a humid state. Specifically, as shown in FIG. 2C , the air conditioner control unit 154 controls the direction of the air released from the air conditioner 14 toward the hair part C1 , the clothes part C2 , and the clothes part C3 determined to be wet.

In addition, the air-conditioning control unit 154 sets the temperature and air volume of the air discharged from the air-conditioning device 14 according to the body surface temperature of the occupant. For example, when the average temperature level of each part of the occupant's body surface is below a fixed value, the occupant's body surface may be very cold, so the air-conditioning control unit 154 sets the temperature of the air discharged from the air conditioner 14 to Set to a higher temperature and set the air volume to stronger.

In addition, the air-conditioning control unit 154 may acquire the outside air temperature data, set the temperature of the air discharged from the air conditioner 14 to a higher temperature when the outside air temperature is low, and set the temperature of the air discharged from the air conditioner 14 to a higher temperature when the outside air temperature is high. The temperature of the released air is set to a lower temperature.

Furthermore, when it is raining outside the vehicle 1, the body surface temperature of the occupant is lower than a predetermined threshold, and it is determined that the occupant's clothes or hair are not wet, the air conditioner control unit 154 sets the air conditioner 14 to the manual start mode. . Here, the manual activation mode means a mode in which the occupant manually activates the air conditioner 14 .

In step S1, the raindrop sensor 11 acquires raindrop data outside the vehicle 1, the temperature sensor 12 acquires body surface temperature distribution data of the occupant in the vehicle 1, and the driver monitoring camera 13 acquires image data of the occupant's clothes or hair. That is, the vehicle control system 10 acquires raindrop data from the raindrop sensor 11 , acquires temperature distribution data from the temperature sensor 12 , and acquires image data from the driver monitoring camera 13 .

In step S2 , rain state determination unit 151 determines whether or not the exterior of vehicle 1 is in a rain state based on the raindrop data output from raindrop sensor 11 . When it is raining state (Yes), the process transfers to step S3. On the other hand, in the case of the non-rainfall state (NO), the processing is then ended.

In step S3 , the temperature difference determination unit 152 determines whether or not the temperature of the occupant's body surface is equal to or greater than a predetermined threshold value based on the temperature distribution data output from the temperature sensor 12 . When the temperature is equal to or greater than the predetermined threshold (Yes), the process proceeds to step S4. On the other hand, when the temperature is less than the predetermined threshold (No), the process proceeds to step S8.

In step S4 , the wet state determination unit 153 determines whether the occupant's clothes or hair are in a wet state based on the image data output from the driver monitoring camera 13 . When it is a wet state (Yes), the process transfers to step S5. On the other hand, in the case of a non-humid state (No), the process transfers to step S8.

In step S5 , the air-conditioning control unit 154 automatically activates the air-conditioning device 14 .

In step S6, the air-conditioning control unit 154 controls the direction of the air discharged from the air-conditioning apparatus 14 toward the location determined to be in a humid state.

In step S7, the air-conditioning control unit 154 sets the temperature and air volume of the air discharged from the air-conditioning device 14 based on the body surface temperature of the occupant. Then, the processing then ends.

In step S8, the air-conditioning control unit 154 sets the air-conditioning apparatus 14 to the manual start mode.

Thus, the vehicle control system 10 can dry the clothes and bodies of the occupants in the vehicle 1 as soon as possible after getting on the vehicle, so that the occupants can eliminate the discomfort caused by being wet by rain. Accordingly, the vehicle control system 10 can provide the occupants with a comfortable driving environment thereafter.

In addition, the vehicle control system 10 further includes: a rain state determination unit 151, which determines whether the exterior of the vehicle 1 is in a rain state based on the raindrop data; and the wet state determination unit 153 determines whether the occupant's clothes or hair are in a wet state based on the image data. Furthermore, the air conditioner control unit 154 automatically activates the air conditioner 14 when the outside of the vehicle 1 is in a rainy state, the occupant's body surface temperature is equal to or higher than a predetermined threshold, and the occupant's clothes or hair are wet.

Thus, the vehicle control system 10 can automatically activate the air conditioner 14 to dry the clothes and hair of the occupant. Thereby, since the occupant can save the operation for setting the air conditioner 14, the time in the process of drying the occupant's clothes or hair can be effectively used.

In addition, the air-conditioning control unit 154 controls the direction of the air discharged from the air-conditioning apparatus 14 toward the site determined to be in a humid state. Thus, the vehicle control system 10 can properly dry the wet parts of the occupant's clothes or hair.

In addition, the air-conditioning control unit 154 sets the temperature and air volume of the air discharged from the air-conditioning device 14 according to the body surface temperature of the occupant. Accordingly, the vehicle control system 10 can perform appropriate drying according to the temperature of the occupant's body surface.

In addition, when the outside of the vehicle 1 is in a rainy state, the body surface temperature of the occupant is lower than a predetermined threshold, and the occupant's clothes or hair are not determined to be in a wet state, the air conditioning control unit 154 sets the air conditioner 14 to be manually activated. Manual start mode. Thus, even if the outside of the vehicle 1 is in a rainy state, the vehicle control system 10 can adjust the air conditioner according to the occupant's preference when the occupant's clothes or hair are not wet.
