  Hereinafter, three examples of the vehicle headlamp device according to the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the embodiments.

  1 and 2 show Embodiment 1 of a vehicle headlamp device according to the present invention. Hereinafter, the configuration of the vehicle headlamp apparatus according to the first embodiment will be described. As shown in FIG. 1, the vehicle headlamp apparatus according to the first embodiment includes a lamp 1, vehicle information collection means 2 as a vehicle information collection unit, and diagnostic code input means as a diagnostic code input unit. 3, a traveling state detection unit 4 as a traveling state detection unit, and a light distribution control unit 5 as a control device.

  The lamp 1 is a headlamp mounted on each of the left and right sides of the front portion of a vehicle (not shown), and changes at least one of a light distribution range, a light distribution shape, and a light distribution brightness. The vehicle has a function of ensuring a wider field of view (visibility) in the traveling direction of the vehicle. The lamp 1 includes a swivel type lamp that is swiveled by a swivel device to change the light distribution of the lamp, and a fixed additional type lamp that is additionally provided at the front of the vehicle. In this example, the lamp 1 is a projector-type lamp that uses a discharge lamp (a so-called high-pressure metal vapor discharge lamp such as a metal halide lamp or a high-intensity discharge lamp (HID)) as a light source. The lamp 1 may be a lamp other than a projector-type lamp that uses a discharge lamp as a light source, such as a semiconductor-type light source such as an LED, a halogen lamp, an incandescent lamp, or the like, a reflective lamp, It may be a type of lamp.

  The vehicle information collecting means 2 detects vehicle information and outputs an information signal to the light distribution control means 5. That is, the vehicle information collecting means 2 collects various vehicle information necessary for control to change the light distribution of the lamp 1. The vehicle information collecting means 2 is composed of, for example, a steering angle sensor, a headlamp switch, and the like.

  The steering angle sensor detects a steering angle (steering angle and synonym) of a steering handle (not shown, synonyms such as a steering wheel and a steering wheel) and a steering direction, and distributes the steering angle signal and the steering direction signal to the light distribution. This is output to the control means 5. That is, the steering angle sensor is used when, for example, the driver runs on a curved road (a road with a left curve or a road with a right curve), and when the vehicle makes a left turn or a right turn on an intersection. A steering angle (rotation angle) and a steering direction (rotation direction) of the steering handle to be steered are detected, and a steering angle signal and a steering direction signal are output to the light distribution control means 5. The steering angle signal and the steering direction signal are obtained as specific numerical data by, for example, networking the steering angle sensor and the light distribution control means 5 mounted on a vehicle. As specific numerical data, for example, numerical data of + 10 ° is obtained when the steering wheel is turned 10 ° to the right, and numerical data of −10 ° is obtained when the steering wheel is turned 10 ° to the left. As specific numerical data, for example, when the steering wheel is turned 10 ° to the right, numerical data of “990” with respect to the neutral value of “1000”, while when the steering wheel is turned 10 ° to the left, It is obtained as numerical data “1010” with respect to the neutral numerical value “1000”. On the other hand, the steering angle signal and the steering direction signal are obtained, for example, as electrical signals output from the steering angle sensor (for example, an optical sensor) mounted on a vehicle to the light distribution control means 5.

  The headlamp switch turns on or off the lamp 1 by a driver operating ON or OFF, and outputs an ON signal (for example, a high level signal) when ON, and an OFF signal (for example, when OFF) (for example, , A low level signal) is output to the light distribution control means 5.

  The diagnostic code input means 3 inputs a diagnostic code transmitted from the diagnostic apparatus and transmits it to the light distribution control means 5 when making a diagnosis using a diagnostic apparatus dedicated to the vehicle headlamp apparatus. Is. Here, when performing an operation check or inspection of the vehicle headlamp device according to the first embodiment, the diagnostic device is connected to a dedicated connection part of the vehicle in a state where the vehicle is stopped, and the diagnostic device The diagnostic code is transmitted to the vehicle headlamp device according to the first embodiment via the network of the vehicle to which the vehicle information collecting means 2 is connected or the dedicated signal line, and the vehicle according to the first embodiment is transmitted. Operations such as operation check and inspection are performed when the headlamp device responds. The diagnostic code input means 3 includes, for example, an unauthorized diagnostic code generated from a vehicle device added later by the user, in addition to the diagnostic code from the diagnostic device dedicated to the vehicle headlamp device. Is also transmitted to the light distribution control means 5.

  The traveling state detection unit 4 detects a state in which the vehicle is traveling or is stopped and outputs a detection signal to the light distribution control unit 5. That is, the running state detecting means 4 detects whether the vehicle is running or stopped, and the light distribution control means 5 determines whether the vehicle is in a running state or in a stopped state. Is output to the light distribution control means 5 as data for determining the above. The data is data in two states, i.e., a running state stop state, or data in a form that can be calculated by the light distribution control means 5 to determine the running state stop state. For example, a vehicle speed sensor is used as the traveling state detection means 4. The traveling state detection means 4 also constitutes vehicle information collection means 2 that detects vehicle information and outputs an information signal to the light distribution control means 5.

  The light distribution control means 5 calculates an optimum light distribution based on detection signals from the vehicle information collection means 2 and the traveling state detection means 4, and controls the lamp 1 so that the optimum light distribution is obtained.

  The operation of the light distribution control means 5 is started. Then, the light distribution control means 5 first determines whether or not a diagnostic code has been input to the diagnostic code input means 3 (is input? S1). This diagnostic code may be a normal diagnostic code transmitted from a diagnostic device dedicated to the vehicle headlamp device, or an incorrect diagnostic code generated from a vehicle device added later by the user, for example. In some cases.

  When the diagnostic code is not input to the diagnostic code input means 3 in (S1), the light distribution control means 5 processes the normal light distribution change of the lamp 1 (normal light distribution change processing S2). ), And then returns to (S1). The normal light distribution change process of the light distribution control means 5 is as follows.

  That is, the vehicle information collection unit 2 collects and detects vehicle information and outputs an information signal to the light distribution control unit 5. Further, the traveling state detection unit 4 detects the traveling state stop state of the vehicle and outputs a detection signal to the light distribution control unit 5. The light distribution control means 5 calculates the optimum light distribution based on the information signal from the vehicle information collecting means 2 and the detection signal from the running state detection means 4, and the lamp 1 is optimally distributed based on the calculation result. Control to obtain As a result, at least one of the light distribution range, light distribution shape, and light distribution brightness of the lamp 1 can be changed to ensure a wider field of view (visibility) in the traveling direction of the vehicle. For example, when the lamp 1 is a swivel type lamp, the optimal light distribution can be obtained by swiveling the lamp 1 via the swivel device. In the case where the lamp 1 is a fixed additional type of lamp, the optimal light distribution can be obtained by adjusting the light amount of the light source of the lamp 1 or adjusting the lighting / extinction of the plurality of lamps 1. .

  When the diagnostic code is input to the diagnostic code input means 3 in (S1), the light distribution control means 5 returns the lamp 1 to the reference state (returns to the reference state S3), and thereafter (S1 Return to). That is, the light distribution control means 5 to which the diagnostic code is input via the diagnostic code input means 3 is in a state where the vehicle is not subjected to movement (that is, diagnosis such as operation check and inspection of the vehicle headlamp device). The lamp 1 is returned to the reference state regardless of the contents of the vehicle information obtained by the vehicle information collecting means 2 and the traveling state detecting means 4. .

  The reference state return of the lamp 1 of the light distribution control means 5 is as follows. That is, when the lamp 1 is a swivel type lamp, when a diagnostic code is input to the diagnostic code input means 3, the lamp 1 swiveled to a set swivel angle is set to a reference state of a reference angle, for example, deflection. Return the angle to the reference angle (standard position after initialization). When the lamp 1 is a fixed additional type of lamp, when the diagnostic code is input to the diagnostic code input means 3, the lamp 1 that has been changed to the set light distribution is turned off instantaneously or dimmed off. To return to the reference state.

  The vehicle headlamp apparatus according to the first embodiment is configured and operated as described above. Hereinafter, the effects of the vehicle headlamp apparatus according to the first embodiment will be described.

For this reason, in the vehicle headlamp device according to the first embodiment, for example, when a diagnostic code is illegally input, the lamp 1 is used as a reference without shifting to the diagnostic mode during the operation of the light distribution change. Since it returns to the state, there is no glare.

  In the vehicular headlamp apparatus according to the first embodiment, when the lamp 1 is a swivel type lamp that is swiveled by the swivel device and changes the light distribution of the lamp, the diagnostic code is supplied to the diagnostic code input means 3. When input, the lamp 1 swiveled to the set swivel angle is returned to the reference state of the reference angle, so there is no glare.

  Further, in the vehicle headlamp device according to the first embodiment, in the case where the lamp 1 is a fixed additional type lamp that is additionally provided at the front portion of the vehicle, a diagnostic code is input to the diagnostic code input means 3. Then, since the lamp 1 that has been changed to the set light distribution is instantaneously extinguished or dimmed and returned to the reference state, glare is not given.

  FIG. 3 shows Embodiment 2 of the vehicle headlamp device according to the present invention. Hereinafter, the vehicle headlamp apparatus according to the second embodiment will be described. The vehicle headlamp device according to the second embodiment is different from the vehicle headlamp according to the first embodiment in the processing steps of the light distribution control means 5. The processing steps of the light distribution control means 5 of the vehicle headlamp apparatus according to the second embodiment will be described below with reference to the flowchart shown in FIG.

  The operation of the light distribution control means 5 is started. Then, the light distribution control means 5 first determines whether or not a diagnostic code has been input to the diagnostic code input means 3 (input is present? S21). This diagnostic code may be a normal diagnostic code transmitted from a diagnostic device dedicated to the vehicle headlamp device, or an incorrect diagnostic code generated from a vehicle device added later by the user, for example. In some cases.

  When the diagnostic code is not input to the diagnostic code input means 3 in (S21), the light distribution control means 5 processes the normal light distribution change of the lamp 1 (normal light distribution change processing S22). ), And then returns to (S21). The normal light distribution change process of the light distribution control means 5 is as described above.

  When the diagnostic code is input to the diagnostic code input means 3 in (S21), the light distribution control means 5 next determines whether the vehicle is running or stopped (stopped). S23). When the vehicle is in a stopped state, the light distribution control means 5 processes the normal light distribution change of the lamp 1 (normal light distribution change process S22), and then returns to (S21). The normal light distribution change process of the light distribution control means 5 is as described above.

  In the above (S23), when the vehicle is in a state other than the stopped state, that is, when the vehicle is in the traveling state, the light distribution control means 5 returns the lamp 1 to the reference state (returns to the reference state S24), Thereafter, the process returns to (S21). That is, the light distribution control means 5 considers the point of making a diagnosis using a diagnostic device dedicated to the vehicle headlamp device when the vehicle is in a stopped state. The lamp 1 is returned to the reference state only when the diagnostic code is input to the diagnostic code input means 3. The return of the reference state of the lamp 1 of the light distribution control means 5 is as described above.

  The vehicle headlamp apparatus according to the second embodiment is a vehicle headlamp that is capable of being diagnosed in consideration of the fact that diagnosis is performed using a diagnostic apparatus dedicated to the vehicle headlamp apparatus when the vehicle is stopped. Only when the diagnostic code is input to the diagnostic code input means 3 in the running state, the lamp 1 is returned to the reference state. Therefore, in the vehicle headlamp device according to the second embodiment, when the diagnostic code is input to the diagnostic code input means 3 when the vehicle is in a stopped state, the light distribution of the lamp 1 changes normally. Therefore, diagnosis can be performed using a diagnostic device dedicated to the vehicle headlamp device.

Is recorded as a history. Since the diagnostic code input storage means 6 needs to hold the record even when the power source of the vehicle headlamp device according to the third embodiment is turned off, a storage element such as an EEPROM or a FlashROM Etc.

  The processing steps of the light distribution control means 5 of the vehicle headlamp device according to the third embodiment will be described below with reference to the flowchart shown in FIG.

  The operation of the light distribution control means 5 is started. Then, the light distribution control means 5 first determines whether or not a diagnostic code has been input to the diagnostic code input means 3 (is input? S31). This diagnostic code may be a normal diagnostic code transmitted from a diagnostic device dedicated to the vehicle headlamp device, or an incorrect diagnostic code generated from a vehicle device added later by the user, for example. In some cases.

  When the diagnostic code is not input to the diagnostic code input means 3 in (S31), the light distribution control means 5 does not leave a record in the diagnostic code input storage means 6 (does not leave a record S32). Then, the process returns to (S31). Alternatively, when the diagnostic code is not input to the diagnostic code input unit 3 in (S31), the light distribution control unit 5 returns to (S31).

  When the diagnostic code is input to the diagnostic code input means 3 in (S31), the light distribution control means 5 next determines whether the vehicle is in a running state or in a stopped state (running) Medium S33). When the vehicle is in a stopped state, the light distribution control unit 5 determines that a diagnosis such as a normal operation check or inspection is performed, and diagnoses that the diagnostic code is input to the diagnostic code input unit 3. No record is left in the code input storage means 6 (no record is left S32), and then the process returns to (S31).

  In the above (S33), when the vehicle is in the running state, the light distribution control means 5 determines that an incorrect diagnostic code has been input, and confirms that the diagnostic code has been input to the diagnostic code input means 3. A record is left in the diagnostic code input storage means 6 (leave a record S34), and then the process returns to (S31). Then, when making a diagnosis of the vehicle headlamp device at a later date, a vehicle device that generates an incorrect diagnostic code by reading an incorrect input of the diagnostic code recorded in the diagnostic code input storage means 6 It is possible to grasp the state of being connected to the vehicle or the state of being connected in the past.

  Thus, in the vehicle headlamp device according to the third embodiment, when the diagnostic code is illegally input to the diagnostic code input means 3 in the traveling state of the vehicle, the diagnostic code is illegally input. It is recorded in the diagnostic code input storage means 6. As a result, the vehicular headlamp apparatus according to the third embodiment performs illegal input of the diagnostic code recorded in the diagnostic code input storage means 6 when diagnosing the vehicular headlamp apparatus at a later date. By reading, it is possible to grasp a state in which a vehicle device that generates an unauthorized diagnostic code is connected to the vehicle or has been connected in the past. Therefore, in the vehicle headlamp device according to the third embodiment, the cause of the problem that the normal operation of changing the light distribution cannot be performed is caused by an incorrect diagnosis code input, or other It can be clearly and easily determined whether it is caused by the cause.

  Further, the vehicle headlamp device according to the third embodiment is similar to the vehicle headlamp device according to the first embodiment when the diagnostic code is input to the diagnostic code input means 3.
