Abstract

PURPOSE:To improve visibility for a side direction by lighting a lamp device, provided so as to irradiate a turning direction when a vehicle turns, when an actual steered angle exceeds a given steered angle set smaller in a high speed than in a low speed based on a steered angle signal and a vehicle speed signal. CONSTITUTION:A left or right winker lamp lighting signal from a winker switch 5, a vehicle speed signal from a vehicle speed sensor 6, a steered angle signal from a steered angle sensor 7, and a head lamp lighting signal from a head lamp lighting switch 8 are inputted in a controller 4 composed of a CPU. The need for irradiation is judged from the head lamp lighting signal in the controller 4, and a right or left cornering lamp R or L is lit when a right or left winker lamp lighting signal is inputted. The input of a vehicle speed signal and a steered angle signal when the winker lamp lighting signal is not inputted, causes the lighting of the cornering lamp R or L by a small steered angle at the time of a high speed, and the lighting by a larger steered angle at the time of a low speed compared with at the time of a high speed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a vehicle lamp device that illuminates the turning direction when the vehicle turns.

[Prior art]

Conventionally, as a vehicle lamp device that illuminates the turning direction when the vehicle turns, as described in Japanese Utility Model Application Publication No. 60-157441 (see FIG. 3), a headlamp 2 is installed at the front end of the vehicle 1, A cornering lamp 3 that illuminates the turning direction when the vehicle turns is provided, and when the headlamp lighting switch is turned on and the turn signal switch or the steering wheel direction detection switch provided on the steering wheel is turned on, the turn signal lamp is turned on. It is known that the cornering lamp 3 on the side where the steering wheel is turned or the side in which the steering wheel is turned is turned on.

[Problem to be solved by the invention]

However, in the above-mentioned conventional vehicle lamp device, the cornering lamp 3 is turned on regardless of the traveling speed of the vehicle, so when the vehicle is traveling at a low speed and only a small steering angle is required, the cornering lamp 3 is turned on. Since the front of the vehicle follows smoothly, illumination from headlamp 2 is sufficient.
Furthermore, since the steering wheel direction detection switch is turned on when the steering angle is greater than a predetermined value, when driving on a winding road such as a mountain road, the steering angle is small and the cornering lamp 3 is turned on. The problem was that there was a risk that it would not work.

SUMMARY OF THE INVENTION An object of the present invention is to provide a vehicle lamp device that can improve lateral visibility by turning on cornering lamps not only when driving around town but also when driving on winding roads such as mountain roads. .

[Means to solve the problem]

In order to achieve the above object, the vehicle lamp device of the present invention is a lamp device (cornering lamp) provided to illuminate the turning direction when the vehicle turns, and includes a steering angle detecting means and a vehicle speed detecting means. Based on the steering angle signal and the vehicle speed signal, the lamp device lights up when the steering angle exceeds a predetermined steering angle, which is set smaller at high speeds than at low speeds.

[Effect]

The vehicle lamp device of the present invention configured as described above includes:
Based on the steering angle signal from the steering angle detection means and the vehicle speed signal from the vehicle speed detection means, a lamp device (cornering lamp) is turned on at a small steering angle at high speeds, and a larger steering angle at low speeds than at high speeds. By turning on the lights, side visibility can be improved not only when driving around town but also when driving on winding roads such as mountain roads.

〔Example〕

Embodiments of the present invention will be described with reference to drawings.

In FIG. 1, a controller 4 consisting of a CPU receives a turn signal for either the left or right turn signal from a turn signal switch 5, inputs a vehicle speed signal from a vehicle speed sensor (vehicle speed detection means) 6, and inputs a vehicle speed signal from a vehicle speed sensor (vehicle speed detection means). Means) A steering angle signal (including steering direction) is input from 7, and a headlamp lighting signal is input from headlamp lighting switch 8.

The controller 4 determines the necessity of illumination from the headlamp lighting signal, and lights the right cornering lamp R or the left cornering lamp L when either the left or right blinker lamp lighting signal is input.

When a vehicle speed signal and a steering angle signal are input when a blinker lamp lighting signal is not input, the cornering lamp is turned on at a small steering angle at high speeds, and is turned on at a large steering angle at low speeds compared to when at high speeds. In Figure 2, ■
is a lit area, and ■ is a non-lit area.

Note that the light is not turned on when the vehicle is stopped and the speed is zero.

According to this configuration, when the turn signal switch 5 is operated at an intersection or the like, the cornering lamp on the side where the turn signal lamp is turned on is turned on, so that driving safety in the city can be ensured.

In addition, on winding roads such as mountain roads, only the steering wheel operation is required without operating the blinker switch 5, and the steering angle signal from the steering angle sensor 7 and the vehicle speed signal from the vehicle speed sensor 6 are used. , when the steering angle and vehicle speed are within the lighting area (2) in FIG.

In this way, based on the steering angle signal from the steering angle sensor and the vehicle speed signal from the vehicle speed sensor, the lighting area of the cornering lamp (at high speeds, the minimum steering angle for turning on is small; at low speeds, the maximum steering angle for turning on is small). The light will turn on when the steering angle and vehicle speed are within the range (large), and will not light when the steering angle and vehicle speed are within the non-lighting range, so when driving at low speed and steering with a small steering angle, the tip of the vehicle will follow the turning speed. Since the vehicle turns, it is possible to fully confirm safety within the irradiation range of the headlights, and there is no need to turn on the cornering lamps.At high speeds, the cornering lamps are turned on even with a small steering angle.

[Effect of idea]

Since the present invention is configured as described above, it produces the effects as described below.

Based on the steering angle signal from the steering angle detection means and the vehicle speed signal from the vehicle speed detection means, the lamp device (
By turning on the cornering lamp) and turning on the lamp device (cornering lamp) at a larger steering angle at low speeds than at high speeds, both visibility is improved not only when driving in the city but also when driving on winding roads such as mountain roads. It is something that can be done to improve one's performance.
