Description

  The present invention relates to a vehicle door locking device, and more specifically, a hazard lamp lighting device in a vehicle having a keyless entry function, and confirmation of locking / unlocking of the hazard lamp lighting device when the keyless entry function is exercised It is related with the lighting control method for performing.

  A keyless flashing hazard lamp (also serves as a turn signal lamp) to confirm the opening / closing of the door lock of the vehicle at a position away from the vehicle when exercising the keyless entry function in a vehicle equipped with a keyless entry system Some have an answer back function (a function for confirming whether a vehicle door is locked or unlocked by blinking a hazard lamp).

FIG. 6 shows a schematic configuration of a keyless entry system having an answer back function.
The keyless entry system having the answer back function includes a keyless entry unit 1A as a control means, a remote controller 10 for operating the keyless entry unit wirelessly, a door lock switch 4, and a hazard lamp 31 that also serves as a turn signal lamp. , 32.

The door lock switch 4 is composed of a switch part 41, an excitation part 42, and terminals 43 and 44 to which the switch part is connected and disconnected. The terminal 43 is connected to the storage battery 5 by power supply lines L1 and L2, and the terminal 44 is a ground line. It is grounded to a vehicle body (not shown) by Le.
The input side of the keyless entry unit 1A is connected to the storage battery 5 by the power supply lines L1 and L3, and the output side is connected to the excitation unit 42 of the door lock switch 4 by the line L4.
Further, the output side of the keyless entry unit 1A is connected to a hazard lamp 31 (for example, for right turn) by a line L8 and to a hazard lamp 32 (for example, for left turn) by a branch line L9 from the line L8.
The hazard lamps 31 and 32 are connected to the hazard / turn signal drive unit 2A by lines L71 and L72, and function as a turn signal lamp by an output signal from a turn signal switch (not shown) before functioning as a keyless entry system. Alternatively, it is configured to function as an output signal hazard lamp from a hazard switch (not shown).

When it is desired to operate and lock the keyless entry, the keyless entry unit 1A is controlled so as to energize the excitation part 42 of the door lock switch 4 by pressing the lock button 11 of the remote controller 10, and therefore the door lock switch 4 is The circuit is closed and a door lock (not shown) is locked (locked). At this time, the keyless entry unit 1A also energizes the lines L8 and L9 intermittently and blinks the hazard lamp.
On the other hand, when unlocking is desired, the keyless entry unit 1A is controlled to stop energization of the excitation part 42 of the door lock switch 4 by pressing the unlock button 12 of the remote controller 10, and therefore the door lock switch 4 is The circuit opens and the door lock (not shown) is unlocked. At this time, the keyless entry unit 1A also energizes the lines L8 and L9 intermittently and blinks the hazard lamp.

  FIG. 7 is a block diagram showing a schematic configuration of a keyless entry system having no answer back function. In contrast to the answer function of FIG. 6, the keyless entry unit 1B (reference numeral 1A in FIG. 6) starts the hazard lamp 31. , 32, the power supply lines L8 and L9 are abolished.

In the keyless entry system with answer back function, a dedicated power supply circuit for connecting from the keyless entry unit to the hazard lamp is provided.
On the other hand, a keyless entry system vehicle without an answerback function does not have such a dedicated power supply circuit. Therefore, an answerback function is attached to a vehicle with a keyless entry system without an answerback function later (for example, a dealer option). This means that a new power circuit will be installed over the entire length of the vehicle (hazard lamps, that is, turn signal lamps are located at both front and rear ends of the vehicle), which is extremely difficult in terms of cost and man-hours. It was.

Here, a signal input means, a keyless entry control circuit that emits a predetermined transmission signal when a signal is input by an operation of the signal input means, and a door lock device that is actuated by a signal of the keyless entry control circuit to activate a door lock In a keyless entry device for automobiles, a circuit configuration in which a keyless entry control circuit lights a turn signal lamp for a certain time at the same time when a signal is inputted to the keyless entry control circuit and a signal to operate the door lock device is issued. A keyless entry device for an automobile provided with the above has been proposed (see, for example, Patent Document 1).
However, as in the above keyless entry system with answer function (see FIG. 6), the apparatus connects the power signal line connecting the turn signal lamp and the keyless entry control circuit to the existing turn signal unit and the turn signal lamp. Separately from the power supply line to be provided, it must be newly provided, and the above-mentioned problems must be solved.

In addition to the above, there has been proposed a technique for simplifying a wire harness used for supplying power for blinking a turn signal lamp without complicating the circuit configuration (see, for example, Patent Document 2).
However, such a technique does not correspond to the keyless entry system and does not solve the above-described problem.
