DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as appropriate.
[0011]
(1) Embodiment FIG. 1 is a block diagram showing an illumination system according to an embodiment of the present invention. In this illumination system 1, the illumination 2 is composed of a plurality of light emitting diodes arranged along the edge of the dashboard of the car, the edge of the lining of the door, and the like. The illumination 2 is configured such that the type of each light emitting diode, the number of light emitting diodes, and the like are selected so as not to interfere with operation even when all light sources are turned on.
[0012]
The system controller (syscon) 3 is a control circuit that monitors the operation of the entire vehicle on which the illumination system 1 is mounted, and outputs vehicle information DC to the lighting pattern generation circuit 5 through a predetermined interface circuit. Here, the vehicle information DC is information indicating the state of the vehicle, and in this embodiment, information on the rotational speed of the engine, information on the vehicle speed, and information on the opening of the accelerator are applied as this information. Has been made.
[0013]
On the other hand, the state detection means 6 acquires and outputs the driver information DB indicating the driver state. In this embodiment, the state detection means 6 detects the heart rate of the driver via the electrodes arranged on the steering wheel 7 of the automobile, and outputs this heart rate information as the driver information DB.
[0014]
The drive circuit 8 drives the individual light emitting diodes constituting the illumination 2 by driving the lighting pattern generation circuit 5.
[0015]
The lighting pattern generation circuit 5 is a control circuit configured by a computer, and lights the illumination 2 via the drive circuit 8. At this time, the lighting pattern generation circuit 5 lights the illumination 2 with a predetermined pattern according to the vehicle information DC and the driver information DB by executing the processing procedure shown in FIG. Thereby, the lighting pattern generation circuit 5 produces the interior of the vehicle with the light of the illumination 2.
[0016]
That is, when the operation starts, the lighting pattern generation circuit 5 proceeds from step SP1 to step SP2, and determines whether or not the driver's heart rate has increased by a predetermined value or more from the driver information DB. If a negative result is obtained here, the lighting pattern generation circuit 5 proceeds to step SP3 and outputs a drive signal so that the illumination 2 is lit with a lighting color corresponding to the engine speed. Specifically, the lighting pattern generation circuit 5 adjusts the illumination 2 so that the lighting color of the illumination 2 gradually changes from blue to green and further from green to red as the engine speed increases. Set the lighting color. As a result, the lighting pattern generation circuit 5 sets the lighting pattern of the illumination 2 so that the lighting color changes according to the rotational speed of the engine.
[0017]
Subsequently, the lighting pattern generation circuit 5 moves to step SP4, sets the illumination 2 to blink according to the lighting color set in step SP3, and sets this blinking to synchronize with the heart rate. As a result, the lighting pattern generation circuit 5 sets the lighting pattern of the illumination 2 to blink according to the heart rate of the driver.
[0018]
Subsequently, the lighting pattern generation circuit 5 moves to step SP5, sets the light quantity of the illumination 2 so that the light quantity at the time of lighting becomes a constant light quantity corresponding to the vehicle speed, and then returns to step SP2. As a result, the lighting pattern generation circuit 5 sets the lighting pattern of the illumination 2 to change in the amount of light according to the vehicle speed. As a result, the lighting pattern generation circuit 5 determines that the driver is driving with a margin when the heart rate of the driver has not increased by a predetermined value or more. Illumination 2 is turned on by the emission color corresponding to the number of rotations of the lamp and the blinking cycle synchronized with the heartbeat.
[0019]
On the other hand, when a positive result is obtained in step SP2, the lighting pattern generation circuit 5 proceeds to step SP6 and determines whether or not the vehicle speed is equal to or higher than a predetermined value (for example, 40 [km / hour]). If a negative result is obtained here, the lighting pattern generation circuit 5 proceeds to step SP3 because it can be considered that the operation can be performed with a sufficient margin. Thereby, even when the vehicle speed is slow, the lighting pattern generation circuit 5 lights the illumination 2 with the light quantity according to the vehicle speed, the emission color according to the engine speed, and the blinking cycle synchronized with the heartbeat.
[0020]
On the other hand, when a positive result is obtained in step SP6, the lighting pattern generation circuit 5 proceeds to step SP7 and determines whether or not the accelerator opening is 50% or more. If a negative result is obtained here, it is considered that the vehicle can be operated with a sufficient margin in this case because the accelerator is not fully depressed. Accordingly, in this case as well, the lighting pattern generation circuit 5 proceeds to step SP3, and lights the illumination 2 with the light amount according to the vehicle speed, the emission color according to the engine speed, and the blinking cycle synchronized with the heartbeat. .
[0021]
On the other hand, if an affirmative result is obtained in step SP7, in this case, it can be determined that there is no margin in operation, and the lighting pattern generation circuit 5 proceeds to step SP8. Here, the lighting pattern generation circuit 5 stops the change of the lighting color depending on the vehicle speed, and switches the lighting of the illumination 2 to the lighting with a warm color such as orange that softens the heart.
[0022]
Subsequently, the lighting pattern generation circuit 5 proceeds to step SP9 where the blinking of the illumination 2 synchronized with the heartbeat is stopped. Subsequently, the lighting pattern generation circuit 5 proceeds to step SP10, where the lighting with a constant light quantity corresponding to the vehicle speed is stopped, and the light quantity of the illumination 2 is changed so that the light quantity changes with a slow cycle such as deep breathing, for example. Set. Thereby, the lighting pattern generation circuit 5 turns on the illumination 2 so as to make the driver calm when the driver has no room, and returns to step SP2.
[0023]
In the above-described configuration, in the illumination system 1, the vehicle information DC indicating the vehicle state based on the vehicle speed, the engine rotation speed, and the accelerator opening is input from the system controller 3 to the lighting pattern generation circuit 5. The heart rate of the driver is detected as the driver information DB indicating the state of the driver, and the heart rate information is input to the lighting pattern generation circuit 5.
[0024]
In the illumination system 1, the illumination 2 is driven by the lighting pattern generation circuit 5 through the drive circuit 8 in accordance with the vehicle information DC and the driver information DB. As a result, in the illumination system 1, the illumination 2 is turned on in accordance with the vehicle information DC and the driver information DB, and a light effect by the illumination 2 is provided in the vehicle. As a result, the driver can check the behavior of his / her car not only with a sense of speed and engine sound but also with light, making the car even more familiar.
[0025]
Specifically, in the illumination system 1, the illumination 2 is turned on by the amount of light according to the vehicle speed, the light emission color according to the engine speed, and the blinking cycle synchronized with the heartbeat, thereby enhancing the feeling of excitement during driving.
[0026]
However, when the vehicle speed increases and the accelerator is fully depressed, there is no room for driving. In such a case, the heart rate also increases. There may also be cases where the driver is drunk with his driving and is in a so-called excited state. Leaving such a case may lead to a serious accident.
[0027]
Thus, in this embodiment, when such a situation is detected, the lighting pattern of illumination 2 is switched extremely, the blinking is stopped, the change in the amount of light according to the vehicle speed is stopped, and further the engine The change in lighting color according to the number of revolutions is stopped. In the illumination 2, the lighting of the previous illumination 2 is stopped in this way, and the illumination 2 is switched to the warm orange lighting which is a psychologically calm color, and more slowly, for example, deep breathing The amount of light of illumination 2 is set so that the amount of light changes according to the cycle. As a result, the illumination system 1 lights up the illumination 2 so as to calm the driver, and not only uses the lighting of the illumination 2 for mere production but also causes the driver to fall psychologically and prevent accidents. It is made to use.
[0028]
According to the above configuration, the illumination installed in the vehicle is turned on according to the vehicle information obtained by detecting the state of the vehicle and the passenger information obtained by detecting the state of the passenger. Thus, the automobile can be made more familiar.
