  FIG. 1 is a block diagram showing a vehicular lamp according to an embodiment of the present invention. 2 to 5 are a flowchart (FIGS. 2 to 4) and a timing chart (FIG. 5) showing the operation of the vehicular lamp described in FIG. 6 and 7 are flowcharts showing a modification of the vehicle lamp shown in FIG. FIG. 8 is an explanatory diagram illustrating an application example of the vehicular lamp illustrated in FIG. 1.

[Vehicle lamp]
The vehicular lamp 1 includes a pair of side lamps 21 and 22, various detection units 31 to 33, and a control unit 4 (see FIG. 1). The pair of side lamps 21 and 22 are installed in the front portion of the vehicle 10 together with the pair of headlamps 23 and 24 and irradiate obliquely forward of the vehicle. The pair of side lamps 21 and 22 includes a right side lamp 21 that illuminates the right side of the vehicle 10 and a left side lamp 22 that illuminates the left side of the vehicle. These side lamps 21 and 22 are arrange | positioned with respect to a pair of headlamps 23 and 24 at the width direction outer side of the vehicle 10, for example. A predetermined light distribution pattern is formed by the side lamps 21 and 22 and the headlamps 23 and 24 (see FIG. 8). For example, in this embodiment, the headlamps 23 and 24 have irradiation ranges R1 and L1 on the front surface of the vehicle 10 and the periphery thereof, and irradiate the visual recognition range when the vehicle 10 goes straight and when the vehicle 10 is gently curved. Further, the side lamps 21 and 22 have irradiation ranges R2 and L2 on the outer side in the vehicle width direction with respect to the irradiation ranges R1 and L1 of the headlamps 23 and 24, respectively. Thereby, the visibility at the time of driving | running | working on a curved road with strong bends, such as an intersection and a residential area, is ensured.

  The various detection units 31 to 33 include a steering angle detection unit 31, an instruction direction detection unit 32, and a vehicle speed detection unit 33. The steering angle detection unit 31 is a sensor that detects the steering angle of the vehicle 10 and sends the detection result to the control unit 4 as a steering angle signal. The indication direction detection unit 32 is a sensor that detects an indication direction of a direction indicator (not shown) of the vehicle 10 and sends the detection result to the control unit 4 as a direction indicator signal. The vehicle speed detection unit 33 is a sensor that detects the traveling speed of the vehicle 10, and sends the detection result to the control unit 4 as a vehicle speed signal.

  The control unit 4 includes a control determination unit 41 and a side lamp drive unit 42, and is configured by, for example, an ECU (Electronic Control Unit) of a vehicle. The control determination unit 41 makes a predetermined determination based on the steering angle signal, the direction indicator signal, and the vehicle speed signal acquired from the various detection units 31 to 33 and turns on the right side lamp 21 and the left side lamp 22. A control signal for control is sent to the side lamp drive unit 42. The side lamp drive unit 42 drives the right side lamp 21 and the left side lamp 22 based on this control signal. Note that the control unit 4 may acquire information necessary for driving the side lamp via an in-vehicle network such as a CAN (controller area network).

[Lighting control of side lights]
Here, when the traveling direction of the vehicle 10 is restricted by the surrounding environment during traveling, the direction indicator may be operated while the vehicle 10 is being steered (turning). For example, when the driver turns left at the front crossroad, if there are no obstacles in the traveling direction, steering is performed in the left direction and the vehicle turns left at the crossroad. However, if there is an obstacle before the intersection, the driver once steers to the right to avoid the obstacle, and then steers to the left and proceeds in the direction intended by the driver. Therefore, the steering direction of the vehicle 10 is not necessarily the traveling direction intended by the driver. On the other hand, in the above case, the direction indicator is operated only for a right turn unless the obstacle avoidance operation is significantly large. That is, the direction indicator is operated as a clear intention indication of the driver regarding the traveling direction of the vehicle 10. Therefore, the lighting control of the lamp is preferably performed in conjunction with the driving operation after appropriately determining the traveling direction intended by the driver.

  From the above viewpoint, in the vehicular lamp 1, the lighting state of the right side lamp 21 and the left side lamp 22 is controlled by the relationship between the steering direction of the vehicle 10 (steering) and the indication direction of the direction indicator ( 2 to 4). First, the direction indicated by the direction indicator is acquired as a direction indicator signal (ST11), and ON / OFF of the direction indicator is determined based on this signal (ST12) (see FIG. 2). If the direction indicator is ON, the side lights 21 and 22 in the indicated direction are lit (ST13). That is, the indication direction of the direction indicator is determined (ST131), and when the indication direction is the right side, the right side lamp 21 is turned on and the left side lamp 22 is turned off (ST132) (see FIG. 3). On the contrary, when the indication direction is the left side, the left side lamp 22 is turned on and the right side lamp 21 is turned off (ST133).

  On the other hand, when the direction indicator is OFF, the steering angle of the vehicle 10 is acquired as a steering angle signal (ST14), and it is determined whether or not the vehicle 10 is being steered based on this steering angle signal. (ST15) (see FIG. 2). When the vehicle 10 is not steered and the vehicle 10 is in a substantially straight traveling state (steering angle≈0), both the right side lamp 21 and the left side lamp 22 are turned off (the lights remain off). (ST16). Conversely, when the vehicle 10 is being steered (steering angle ≠ 0), lighting control of the side lights 21 and 22 in the steering direction is performed based on the acquired steering angle signal (ST17). .

  In the lighting control of the side lamps 21 and 22 (ST17), first, the lighting state of the side lamps 21 and 22 on the steering direction side is determined (ST171) (see FIG. 4). Then, when the side lights 21 and 22 on the steering direction side are turned off, a predetermined lighting steering angle for turning on the side lights 21 and 22 and the steering angle are compared (ST172). When the steering angle is smaller than the predetermined lighting steering angle, the extinguishing state of the side lights 21 and 22 on the steering direction side is maintained. Conversely, when the steering angle is equal to or greater than the predetermined lighting steering angle, the side lights 21 and 22 on the steering direction side are lit (ST173). As a result, when the steering angle of the vehicle 10 is large, for example, when the vehicle 10 is in a right or left turn state or is in a sharp curve, the traveling direction of the vehicle 10 is appropriately irradiated by the corresponding side lights 21 and 22. Thus, driving safety is ensured.

  On the other hand, when the side lights 21 and 22 on the steering direction side are lit, a predetermined turn-off steering angle for turning off the side lights 21 and 22 is compared with the steering angle (ST174). When the steering angle is larger than the predetermined turn-off steering angle, the lighting state of the side lights 21 and 22 on the steering direction side is maintained. Conversely, when the steering angle is equal to or less than the predetermined turn-off steering angle, the side lights 21 and 22 on the steering direction side are turned off (ST175). That is, when the steering angle becomes small and the vehicle 10 goes straight, the side lights 21 and 22 are turned off.

  Next, a specific example of the above control will be described with reference to the timing chart of FIG. First, in the initial state (T0), the steering angle is 0, the vehicle 10 is in a straight traveling state, and the side indicators 21 and 22 are turned off because the direction indicator is not operated. Next, when the vehicle 10 starts to turn right due to a sharp curve or the like, the steering angle of the vehicle 10 gradually increases. At this time, the direction indicator is not operated. When the steering angle reaches a predetermined lighting steering angle, the right side lamp 21 is turned on (T1), and light is emitted in the turning direction of the vehicle 10. Next, when the vehicle 10 returns to the straight traveling state, the steering angle gradually decreases. At this time, the direction indicator is not operated. When the steering angle reaches a predetermined turn-off steering angle, the lit right side lamp 21 is turned off (T2). The above operation is the same when the vehicle 10 turns to the left (T3, T4).

  When the vehicle 10 makes a right turn at an intersection or the like, first, the direction indicator is operated to the right side, and accordingly, the right side lamp 21 is lit (T5). Thereby, light is irradiated in the traveling direction of the vehicle 10. Then, when the vehicle 10 has finished turning right and the direction indicator is turned off, the right side lamp 21 is turned off accordingly (T6). The above operation is the same when the vehicle 10 makes a left turn (T7, T8).

  Next, when the steering direction of the vehicle 10 and the instruction direction of the direction indicator are different, the lighting control of the side lights 21 and 22 is performed as follows. Here, a case where the direction indicator is operated to the left side when the vehicle 10 turns to the right will be described as an example. When the turning angle reaches a predetermined right lighting rudder angle while the vehicle 10 is turning to the right, the right side lamp 21 is lit accordingly (T9). When the direction indicator is operated to the left during the right turn, the operation of the direction indicator is given priority and lighting control of the side lamps 21 and 22 is performed. That is, the right side lamp 21 is lit when turning right, but if the direction indicator is operated to the left during the right turn, the right side lamp 21 is turned off and the left side lamp 22 is lit ( T10). Thereby, lighting control of the side lights 21 and 22 according to a driver's intention display is performed.

  If the direction indicator is turned off while the vehicle 10 is turning, the side lamp 22 (21) on the direction direction side of the direction indicator is turned off, and the side lamp 21 (22) in the turning direction is again turned on. Light.

  As described above, in this vehicular lamp 1, in the normal state, the side lights 21 and 22 on the same side as the steering direction of the vehicle 10 or the indication direction of the direction indicator are turned on, and the steering direction and direction of the vehicle 10 are illuminated. When the pointing direction of the indicator is different, the side lamp 21 (22) on the same side as the pointing direction of the direction indicator is turned on and the side lamp on the same side as the steering direction of the vehicle 10 is turned on. 22 (21) is turned off (see FIGS. 2 to 5). That is, when the steering direction of the vehicle 10 is different from the direction indicated by the direction indicator, the lighting direction of the side lights 21 and 22 is controlled with priority given to the direction indicated by the direction indicator.

  In such a configuration, the lighting control of the side lights 21 and 22 is performed based on the driver's clear intention display (operation of the direction indicator) regarding the traveling direction of the vehicle 10. Thereby, since the traveling direction of the vehicle 10 is appropriately irradiated, there is an advantage that the driver's field of view is ensured particularly during night driving, and driving safety is improved.

[Additional matter 1]
In this vehicle lamp 1, when the side lamp 22 (21) on the same side as the steering direction of the vehicle 10 is turned on, the direction indicator of the vehicle 10 indicates the opposite direction to the steering direction of the vehicle 10. It is preferable that the side lamp 22 (21) on the same side as the steering direction of the vehicle 10 is turned off after satisfying a predetermined turn-off condition (see FIG. 6). That is, when the steering direction of the vehicle 10 and the direction indicated by the direction indicator are different, the side indicator 21 (22) on the direction indicator side is lit, and the side indicator 22 (21 on the steering direction side) is turned on. ) Goes off. At this time, the side lamp 21 (22) on the direction indicator side is not turned off immediately, but is turned off after satisfying a predetermined turn-off condition. For this reason, a time difference occurs between the lighting of the side lamp 21 (22) on the direction indicator side and the extinguishing of the side lamp 22 (21) on the steering direction side.

  In such a configuration, the side lamp 22 (21) on the steering direction side of the vehicle is lit until a predetermined extinction condition is satisfied even after the turn indicator of the vehicle is operated. As a result, the field of view in the traveling direction (steering direction) of the vehicle at the present time is secured, so that there is an advantage that the safety of traveling is secured.

  Moreover, in said structure, it is preferable that the side lamp 21 (22) on the same side as the direction of a direction indicator of a vehicle lights immediately after operation of a direction indicator. As a result, the field of view of the traveling direction (indicated direction of the direction indicator) intended by the driver is quickly secured, and there is an advantage that the safety of traveling is improved.

  In this embodiment, when the side lamp 22 (21) on the steering direction side is lit (ST21), when the vehicle direction indicator is operated, the steering direction of the vehicle and the direction indicated by the direction indicator are changed. Compared (ST22) (see FIG. 6). At this time, when the steering direction of the vehicle coincides with the indication direction of the direction indicator, the lighting state of the side lamp 22 (21) on the steering direction side is maintained as it is. On the other hand, when the steering direction of the vehicle is different from the direction indicated by the direction indicator, first, the side lamp 21 (22) on the direction direction side of the direction indicator is immediately turned on (ST23). Thereby, the field of view in the traveling direction intended by the driver is quickly secured. Next, it is determined whether or not a predetermined turn-off condition for turning off the side lamp 22 (21) on the steering direction side is satisfied (ST24). When the turn-off condition is satisfied, the side light 22 (21) on the steering direction side is turned off. When the turn-off condition is not satisfied yet, the side light 22 (21) on the steering direction side is turned off. The lighting state is maintained. Thereby, the visibility of the traveling direction of the vehicle at the present time is secured.

  In the above configuration, after the side lamp 22 (21) on the same side as the steering direction of the vehicle 10 is turned off, the side lamp 21 (22) on the same side as the direction indicated by the direction indicator of the vehicle is turned on. You may do it (refer FIG. 6). That is, until the side lamp 22 (21) on the steering direction side is turned off, the side lamp 21 (22) on the indication direction side is not lit, and one side lamp (the side lamp 22 (steering direction side lamp 22 ( Only 21)) lights up. In such a configuration, there is an advantage that the power consumption of the lamp is reduced and a circuit configuration of the lamp is simplified compared to a configuration in which both the side lamps 21 and 22 are turned on simultaneously. For example, in the latter advantage, only one side lamp is sufficient for the switching elements (relays, transistors), harnesses, and fuses used when the lamp is turned on.

  In this embodiment, when the side lamp 22 (21) on the steering direction side is lit (ST31), when the vehicle direction indicator is operated, the steering direction of the vehicle and the direction indicated by the direction indicator are changed. Compared (ST32) (see FIG. 7). At this time, when the steering direction of the vehicle coincides with the indication direction of the direction indicator, the lighting state of the side lamp 22 (21) on the steering direction side is maintained as it is. On the other hand, if the steering direction of the vehicle is different from the direction indicated by the direction indicator, first, whether or not a predetermined turn-off condition for turning off the side lamp 22 (21) on the steering direction side is satisfied. Determination is made (ST33). When the turn-off condition is satisfied, the side light 22 (21) on the steering direction side is turned off. When the turn-off condition is not satisfied yet, the side light 22 (21) on the steering direction side is turned off. The lighting state is maintained. Thereby, the visibility of the traveling direction of the vehicle at the present time is secured. Next, after the side light 22 (21) on the steering direction side is turned off, the side light 21 (22) on the direction direction side of the direction indicator is turned on (ST35). Thereby, the field of view in the traveling direction intended by the driver is secured.

  In the above configuration, it is preferable that the predetermined turn-off condition for turning off the side lamp 22 (21) on the same side as the steering direction of the vehicle 10 is the passage of a predetermined time. In such a configuration, there is an advantage that the lighting control of the side lights 21 and 22 can be performed by simple software processing. For example, in the example shown in FIG. 6, after the side lamp 21 (22) on the pointing direction side of the turn indicator is turned on (ST23), the side lamp 22 (21) on the steering direction side is turned off after a predetermined time has elapsed. (ST25). In the example shown in FIG. 7, after a predetermined time has elapsed since the operation of the direction indicator, the side lamp 22 (21) on the steering direction side is turned off after the predetermined time has elapsed.

  In the above configuration, it is preferable that the predetermined turn-off condition for turning off the side lamp 22 (21) on the same side as the steering direction of the vehicle 10 is a vehicle speed equal to or lower than a predetermined value. That is, the side lamp 22 (21) on the steering direction side is turned off on condition that the vehicle speed is equal to or less than a predetermined value. In such a configuration, when the vehicle 10 is traveling at a considerable vehicle speed when the vehicle 10 is turning (at the time of steering), the lighting state of the side light 22 (21) on the steering direction side is maintained and the driver's field of view is maintained. Secured. Thereby, there exists an advantage by which the safety | security of driving | running | working is ensured. The vehicle speed is detected by the vehicle speed detection unit 33 and acquired by the control unit 4 as a vehicle speed signal.

  In the above configuration, it is preferable that the predetermined turn-off condition for turning off the side lamp 22 (21) on the same side as the steering direction of the vehicle 10 is the stop state of the vehicle 10. That is, until the vehicle 10 stops, the lighting state of the side light 22 (21) on the steering direction side is maintained, and the driver's field of view is secured. Thereby, there exists an advantage by which the safety | security of driving | running | working is ensured more appropriately. Further, since it is easier to determine whether or not the vehicle 10 is in the stop state than the lighting control using the vehicle speed, there is an advantage that software processing for controlling the lamp is simplified.

[Additional matter 2]
Moreover, in this vehicle lamp 1, it is preferable that the side lights 21 and 22 are turned off instantaneously when the lights are turned off. Such a configuration is advantageous in that noise due to electromagnetic waves is less likely to occur when the side lights 21 and 22 are turned off, and thus it is difficult to affect other devices (for example, radio and ECU).

  However, the present invention is not limited to this, and the side lights 21 and 22 may be turned off while being dimmed when the lights are turned off. That is, the side lights 21 and 22 are turned off while the light control is performed. In such a configuration, since the appearance of the lamp is improved when the side lights 21 and 22 are turned off, there is an advantage that the commercial value of the lamp is improved.

  As described above, the vehicular lamp according to the present invention is useful in that it can improve traveling safety by appropriately irradiating the traveling direction intended by the driver.
