Abstract

(57) [Summary] [Object] The present invention aims to achieve a device capable of changing the blinking speed of a direction indicator lamp by using a circuit of an existing flasher unit. The present invention is characterized by having a turn-on time control circuit for a turn signal lamp of a vehicle and a running condition detection unit for instructing its operation. According to the present invention, the blinking speed of the turn signal lamp can be changed according to the traveling situation.

Description

[Detailed description of the device]

[0001]

[Fields of use for producing vegetables]

 The present invention relates to a control device for a turn signal lamp mounted on a vehicle.

[0002]

[Prior art]

 Conventionally, the vehicle direction indicator light has been turned on and off at regular intervals regardless of the driving situation. The visibility of the vehicle from the surroundings will be improved if the blinking speed changes slowly corresponding to the speed at low speed and fast at high speed. However, in order to achieve this purpose, it must be replaced with a conventional flasher unit, connected in parallel with a conventional flasher unit, or installed in devices that require wiring to detect vehicle speed. Became difficult.

[0003]

[Problems to be solved by the device]

 The present invention has been made in view of the above-mentioned conventional problems, and utilizes the circuit provided in the conventional vehicle flasher unit and the wiring of the conventional vehicle direction indicator lamp to improve the engine. An object of the present invention is to provide a vehicle-direction indicator light whose blinking speed changes according to the traveling situation by simply connecting to the wiring of a conventional direction indicator light by detecting a signal proportional to the rotation speed.

[0004]

[Means for Solving the Problems]

 The present invention for achieving the above object is characterized by having a lighting time control circuit for a vehicle turn signal lamp and a running condition detection unit for instructing the operation thereof.

[0005]

[Action]

 The vehicle turn signal control device of the present invention configured as described above is operated as follows by connecting in series between the existing flasher unit and the turn signal. When the lighting signal of the turn signal lamp is output from the existing flasher unit, a signal that is controlled during the lighting time determined by the traveling state detection unit is output, and the turn signal lamp is thereby turned on. When the turn-on time is short, the flasher unit flashes faster because the load on the flasher unit decreases.

【Example】

 An embodiment of the present invention will be described below with reference to FIG.

When the direction indicating switch L side of the vehicle is turned on, a direction indicating lamp drive signal of 2 Hz to 1 Hz is input to LIN. This signal is analyzed for the engine speed by the running condition detection unit in this circuit, and if the engine speed is lower than the predetermined reference, IC1 outputs L level. As a result, the-input terminal of IC2 in the lighting time control circuit becomes L level and the output becomes H level. When a current flows through the base of TR1, TR1 is turned on and TR2 is activated. Therefore, TR2 outputs a signal synchronized with LIN from LOUT. When the engine speed analyzed by the running condition detector is higher than the predetermined reference, IC1 outputs H level. As a result, the signal that has passed through the integrating circuit composed of R1 and C1 is input to the-input terminal of IC2 in the lighting time control circuit, which causes the output of IC2 to go to L level after a certain period of time, and TR1 Turn it off. As a result, TR2 outputs a short, time-controlled signal. When the output time is controlled to be shorter than that of TR2, the total load on the flasher unit becomes smaller, which speeds up the operation cycle of the flasher unit, and the object of the present invention is achieved. The same applies when the direction indicating switch R side of the vehicle is turned on.

[Other Examples]

 Other examples include the following examples. (1) An acceleration sensor is used in the running condition detection unit of the present invention. (2) The driving condition detection unit of the present invention is manually operated, and the driver or the like operates the lighting time control circuit of the vehicle direction indicator light according to the condition.

[Effect of device]

 As is apparent from the above description, according to the present invention, it is possible to change the blinking speed of the turn signal lamp only by connecting the device according to the present invention to the wiring of the conventional vehicle turn signal light.
