Of these, the millimeter-wave radar sensor generally has a detectable distance of about 120 m for automobiles. By the way, when the vehicle speeds of the following vehicles 2, 3 and 4 are 100 km / h, the following vehicles 2, 3 and 4 should be detected about 4.3 seconds before reaching the own vehicle (motorcycles 10 and 40). Becomes possible. Further, the image pickup distance of the infrared camera is 120 m or more. These millimeter-wave radar sensors and infrared cameras can detect the following vehicles 2, 3 and 4 even when the driving environment conditions such as fog and rain are poor. The image information from the image pickup apparatus and the information including the distance from the detection sensor (for example, millimeter wave radar information) are transmitted to the control means 63 as a detection signal.

Here, the parking / stopping illuminator 61 and the detecting means 62 may be separate bodies, but may be configured as an integrated unit as shown in FIG. For example, when the parking / stopping illuminator 61 and the detecting means 62 are configured as an integrated unit 64 shown in FIG. 4 (A), the plurality of lamps 65 constituting the parking / stopping illuminator 61 of the unit 64. The parking / stopping illuminator 61 is arranged side by side on the rear side, and the detecting means 62 is arranged on the front side of the unit 64.

The parking / stopping illuminator 61 is arranged vertically and vertically on the left side and the right side, and the detecting means 62 is arranged at the center of the unit 66 in the left-right direction.

When the parking / stopping illuminator 61 implements the side illumination A in these units 64 and 66, in the unit 64, all the lamps 65 of the right or left lamp 65 group from the central position in the left-right direction are lit. In the unit 66, all the lamps 65 of the left lamp 65 group or the right lamp 65 group are lit. Further, when the parking / stopping illuminator 61 performs the rear illumination B in the units 64 and 66, in the unit 64, a plurality or all of the lamps 65 in the adjacent row of lamps 65 are lit, and the unit 66 is present. The lamps 65 of each of the left and right lamp 65 groups are lit.

The control means 63 shown in FIG. 3 controls the operation of the parking / stopping illuminator 61 based on the detection signal from the detection means 62 and the sensor information from the vehicle speed sensor 67, the seating sensor 68, and the stand sensor 69. That is, when the control means 63 recognizes the information regarding the following vehicles 2, 3 and 4 by the detection signal from the detection means 62, and the predetermined conditions are determined by the sensor information from the vehicle speed sensor 67, the seating sensor 68 and the stand sensor 69. When it is determined that the above conditions are satisfied, the parking / stopping illuminator 61 is activated to illuminate at least one of the side road surface and the rear road surface of the own vehicle (motorcycles 10 and 40) (parking / stopping lighting). Let me.

The control means 63 is installed, for example, below the seat 29 as shown in FIG. 1, or installed on the front portion of the vehicle body cover 12 (a portion that covers the periphery of the steering mechanism 43 from the rear) as shown in FIG. Has been done.

Regarding the above-mentioned information regarding the following vehicles 2, 3 and 4, when the detection means 62 is an image pickup device (for example, an infrared camera), the control means 63 performs image processing (for example) of image information which is a detection signal from the detection means 62. These are the vehicle types of the following vehicles 2, 3 and 4 (FIGS. 5 and 6) obtained by performing pattern matching and the like. The control means 63 recognizes the following vehicle 2 as a large four-wheeled vehicle such as a truck or a bus, the following vehicle 3 as a small four-wheeled vehicle such as an ordinary passenger car, and the following vehicle 4 as a motorcycle.

Further, the information regarding the following vehicles 2, 3 and 4 is based on the distance information which is the detection signal from the detection means 62 when the detection means 62 is a detection sensor (for example, a millimeter wave radar sensor or the like). When the inter-vehicle distance between the following vehicles 2, 3 and 4 and the own vehicle (motorcycles 10, 40) is acquired and the control means 63 determines that the inter-vehicle distance has reached a predetermined value, the following vehicles 2, 3, 4 It is a predetermined inter-vehicle distance between the vehicle and the own vehicle (motorcycles 10, 40).
The control means 63 can grasp the types and sizes of the following vehicles 2, 3, and 4 from the information on the size of the radar image obtained by the millimeter-wave radar sensor, and can grasp the types and sizes of the following vehicles 2, 3, and 4, and can be used for small four-wheeled vehicles and large four such as trucks or buses. It can be identified as a wheeled vehicle or a motorcycle. Therefore, even when the detection means 62 is a detection sensor, the vehicle types of the following vehicles 2, 3 and 4 can be obtained as the information regarding the following vehicles 2, 3 and 4 from the information from the detection sensor.

The above-mentioned predetermined conditions are all conditions of the parked / stopped state of the own vehicle (motorcycles 10 and 40), the non-ride state of the driver 5 in the own vehicle, and the independent state of the own vehicle. Of these, the parked / stopped state of the own vehicle is determined by detecting the rotation speed of the front wheels 19 and 44 installed at the lower ends of the front forks 17 and 45 shown in FIGS. 1 and 2, for example, the own vehicle (motorcycles 10 and 40). ) Is a state in which the vehicle speed sensor 67 that detects the vehicle speed outputs zero vehicle speed as sensor information.

Further, in the non-ride state of the driver 5 on the own vehicle (motorcycles 10 and 40), for example, the OFF signal is output as sensor information from the seating sensor 68 built in the seats 29 and 51, and the driver 5 is parked. It is in a state of not being seated on the seats 29 and 51 of the own vehicle (motorcycles 10 and 40) in the stopped state. Further, the self-supporting state of the own vehicle (motorcycles 10, 40) is such that the center stand 36, 56 or the side stand 55 is erected from the stand sensor 69 installed near the center stands 36, 56 or the side stand 55, for example. This is a case where the ON signal is output as sensor information and the own vehicle (motorcycles 10, 40) is in an independent state. One of the conditions is that the self-sustaining state of the own vehicle is one of the conditions because it is difficult for the motorcycles 10 and 40 in the overturned state to irradiate a wide range of road surfaces around the motorcycles 10 and 40. ..

As described above, the control means 63 operates the parking / stopping illuminator 61 when the information regarding the following vehicles 2, 3 and 4 is recognized and when the predetermined conditions are satisfied, and the road surface of the road 1 Is irradiated with lighting (parking / stopping lighting), and at this time, at least one of the irradiation position, irradiation range, irradiation direction, and illumination intensity of the illumination can be changed according to the vehicle types of the following vehicles 2, 3, and 4.

That is, as shown in FIG. 6, the driver's seat of the large four-wheeled vehicle is higher than the road surface of the road 1 as compared with the small four-wheeled vehicle and the motorcycle. Therefore, the driver of this large four-wheeled vehicle can easily overlook the small-sized motorcycles 10 and 40 parked and stopped at a close distance. Therefore, when the control means 63 recognizes that the small four-wheeled vehicle or the motorcycle is the following vehicle 3 or 4, the lighting emitted from the parking / stopping illuminator 61 is set as the rear lighting B, and the basic lighting intensity is Although it is "strong", the lighting intensity may be set to a medium level in good weather conditions. On the other hand, when the large four-wheeled vehicle is the following vehicle 2, the control means 63 sets the lighting emitted from the parking / stopping illuminator 61 as the side lighting A, or the side lighting A and the rear lighting B, and illuminates the vehicle. By increasing the intensity and further blinking or swinging the illuminated portion, the driver of the following vehicle 2 is made to recognize the existence of the own vehicle from a long distance.

Since it is configured as described above, according to the present embodiment, the following effects (1) to (4) are obtained.
(1) As shown in FIGS. 5 and 6, the parked and stopped illuminators 61 of the parked and stopped motorcycles 10 and 40 are on at least one of the side and rear road surfaces of the motorcycles 10 and 40 which are their own vehicles. By irradiating the lighting (parking / stopping lighting), the existence of the own vehicle can be revealed to the surrounding vehicles (2, 3 and 4) in particular around the own vehicle (motorcycles 10 and 40). As a result, even when the driving environment conditions such as fog and rain are poor, the possibility that the own vehicle, which is a small motorcycle size 10 or 40, is overlooked by the following vehicles 2, 3 and 4 is reduced. Therefore, contact between the own vehicle (motorcycles 10, 40) and the following vehicles 2, 3, 4 is avoided in advance, and preventive safety can be realized.

(2) The control means 63 irradiates lighting (parking / stopping lighting) from the parking / stopping illuminator 61 when at least recognizing information regarding the following vehicles 2, 3 and 4. Therefore, power saving can be realized as compared with the case where the parking / stopping illuminator 61 continuously irradiates the illumination.

(3) When the detection means 62 (imaging device) recognizes that the large four-wheeled vehicle is the following vehicle 2, the control means 63 sets the lighting emitted by the parking / stopping illuminator 61 as the side lighting A or lighting. By increasing the intensity, blinking, etc., the existence of the own vehicle (motorcycles 10, 40) in the parked / stopped state is effectively revealed. Therefore, since the driver of the following vehicle 2 which is the large four-wheeled vehicle can be surely recognized the existence of the own vehicle (motorcycles 10, 40) from a long distance, preventive safety can be effectively realized.
