Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vehicle electrical component control device, and more particularly to an electrical component control technique for reducing a driver's operation load on a wiper or a headlight when a vehicle is stopped due to a signal waiting or the like.

[0002]

[Prior Art]

 Conventionally, wipers and headlights, which are electric components of vehicles, are operated by separate operation switches near the steering wheel, such as high speed, low speed, and intermittent for wipers, and high beam, low beam, and small for headlights. As described above, the circuit configuration is such that the operation can be switched in multiple stages. And conventionally, these switch operations are performed manually by a driver.

[0003]

[Problems to be solved by the device]

 For this reason, for example, if the driver stops at a traffic light while driving the vehicle on a rainy night, the driver sets the transmission shift lever to neutral and operates the parking brake lever. Operate the wiper switch or light switch to turn off the wiper power or change the headlight to a small size in order to avoid exhaustion. And, when starting the vehicle, the reverse operation had to be performed.

Therefore, particularly when driving the vehicle on a rainy night or the like, many operations are required at the time of stopping and starting, which imposes a burden on the driver. In addition, it is dangerous to turn off the light when starting the vehicle. As a technique for automatically switching the operation of the headlight and the wiper, for example, those disclosed in Japanese Utility Model Publication No. 62-150238, Japanese Utility Model Publication 59-179743, and Japanese Utility Model Publication No. 62-54860 are disclosed. However, all of these control the operation switching according to the vehicle speed, and the operation switching is performed while the vehicle is traveling, not when the vehicle is stopped.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to reduce the burden on the driver by reducing the operations at the time of stopping and starting the vehicle.

[0006]

[Means for Solving the Problems]

 Therefore, the present invention provides a vehicle stop detection means for detecting a vehicle stop state, and an operation of at least one of a wiper and a headlight capable of performing a plurality of steps of operation switching when the vehicle stop detection means detects the vehicle stop state. Is provided with an operating state switching means capable of automatically switching from the current operating state to an operating state one step lower, and a manual selection switch capable of selecting whether the operating state switching means is activated or inactivated. ..

[0007]

[Action]

 In such a configuration, when the wiper or the headlight is in the operating state, the selection switch is set to the operating state switching means operating position. Then, when the vehicle stop detection means detects the stop of the vehicle, the operation state switching means operates to move the operating wiper or headlight down one step, for example, in the wiper, the high speed becomes low speed, The low speed is intermittent, the intermittent is stopped, and the headlight automatically switches high beam and low beam to small.

Further, when the wiper or the headlight is not operated, the selection switch may be placed in the operating state switching means non-operating position.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1 showing a circuit diagram of this embodiment, a key switch 3 is connected to a battery 1 via a fuse 2, and a wiper switch 4 is connected in series to the key switch 3. A light switch 5 is connected to the battery 1 in parallel with the key switch 3 and the wiper switch 4.

The wiper switch 4 has four positions: a high position for driving a wiper (not shown) at high speed, a low position for driving at low speed, an intermittent position for intermittent driving, and an OFF position. A terminal is provided. An electromagnetic relay 6 is provided between the wiper switch 4 and a wiper driving wiper motor (not shown) for automatically switching the operating state of the wiper to the operating state one step lower when the vehicle is stopped. ing.

The electromagnetic relay 6 is configured to include three movable contacts 6a, 6b, 6c which are interlocked with each other, and an exciting coil 6d for exciting and driving the movable contacts 6a to 6c. One end of the movable contact 6a is connected to the high position terminal of the wiper switch 4, and the other end is switchably connectable to fixed contacts a and b respectively connected to the high speed terminal and the low speed terminal on the wiper motor side. The movable contact 6b can be switched and connected to fixed contacts c and d, one end of which is connected to the low position terminal of the wiper switch 4 and the other end of which is connected to the low speed terminal and the intermittent terminal on the wiper motor side, respectively. One end of the movable contact 6c is connected to the intermittent position terminal of the wiper switch 4, and the other end is an OFF contact that electrically disconnects the fixed contact e connected to the intermittent terminal of the wiper motor and the wiper motor. It is configured to be switchable. The exciting coil 6d is connected in series to a series circuit of a parking brake switch 7, a neutral switch 8 and a selection switch 9, which are connected in parallel to the wiper switch 4 and the light switch 5 in series with the key switch 3. ing.

The light switch 5 has a high position for turning on the high beam lamp 10A of the headlight 10, a low position for turning on the low beam lamp 10B, and a small position for turning on the small lamp 10C. There are four terminals at the small position and at the OFF position. An electromagnetic relay 11 is provided between the lamp switch 5 and the headlight 10 to automatically switch the operating state of the lamp to the operating state one step lower when the vehicle is stopped.

The electromagnetic relay 11 includes two movable contacts 11a and 11b which are interlocked with each other, and an exciting coil 11c which excites and drives the movable contacts 11a and 11b. One end of the movable contact 11a is connected to the high position terminal of the light switch 5, and the other end is switchably connectable to fixed contacts f and g connected to the high beam lamp 10A and the small lamp 10C, respectively. 11b has one end connected to the low position terminal of the light switch 5, and the other end is switchably connectable to fixed contacts h and i which are connected to the low beam lamp 10B and the small lamp 10C, respectively. The small position terminal of the lamp switch 5 is directly connected to the small lamp 10 C without the electromagnetic relay 11. The exciting coil 11c is similar to the exciting coil 6d of the electromagnetic relay 6, and is serially connected to a series circuit of a parking brake switch 7, a neutral switch 8 and a selection switch 9.

Therefore, if the selection switch 9 is turned on, the neutral position of the transmission is detected by detecting the neutral position of the transmission based on the operation of the shift lever and the parking brake lever by the driver when the vehicle is stopped. When the parking brake switch 7 is turned on, the electromagnetic relays 6 and 11 are excited, and if the wiper and the headlight 10 are operating, the operating state is automatically lowered by one step. Here, the parking brake switch 7 and the neutral switch 8 correspond to vehicle stoppage detection means, and both electromagnetic relays 6 and 11 correspond to operation state switching means.

Next, the operation will be described. When the key switch 3 is turned on, if the wiper switch 4 is operated to set the high, low or intermittent positions, electric power is supplied to the wiper motor and the wiper is driven at each speed. Also, since the light switch 5 is directly connected to the battery, if the key switch 3 is not turned on and the light switch 5 is operated to set the high, low or small positions, the high beam lamp 10A and the low beam lamp 10B respectively. Alternatively, the small lamp 10C is turned on.

Then, when the wiper and the headlight 10 are operated to drive, if the selection switch 9 is turned on, the vehicle is stopped, for example, waiting for a signal, the parking brake lever is pulled, and the transmission is neutralized. When set to, the parking brake switch 7 and the neutral switch 8 are turned on, and the exciting coils 6d and 11c of the electromagnetic relays 6 and 11 are excited. As a result, the movable contact points 6a to 6c and 11a and 11b are switched in conjunction with each other, and the operating state of the wiper and the headlight 10 is switched to the operating state one step lower.

For example, regarding the wiper, when the wiper switch 4 is in the high position, the movable contact 6a is switched from the fixed contact a to the fixed contact b side and is switched and connected to the low speed terminal side of the wiper motor to change from the high speed to the low speed. At low speed, the movable contact 6b switches from the fixed contact c to the fixed contact d side at the low position, and is switched and connected to the intermittent terminal side of the wiper motor to start the intermittent operation from the low speed. At times, the movable contact 6c is switched from the fixed contact e to the OFF contact side, the wiper motor is stopped, and the wiper is stopped.

On the other hand, regarding the headlight 10, when the light switch 5 is in the high position, the movable contact 11a is switched from the fixed contact f to the fixed contact g side, and the high beam lamp 10A is switched and connected to the small lamp 10C side. Further, at the low position, the movable contact 11b is switched from the fixed contact h to the fixed contact i side and is switched and connected from the low beam lamp 10B to the small lamp 10C side. Also, when in the small position, the small lamp 10C is maintained in the lighting state as it is.

According to this configuration, if the selection switch 9 is turned on, the wiper and the headlight 10 are automatically turned on by operating the parking brake lever and the transmission shift lever when the vehicle is stopped. Since it is controlled to a lower level, when driving with the wiper and headlight 10 operated in a rainy night etc., the driver operates the wiper switch 4 and the light switch 5 by himself / herself as usual when the vehicle is stopped. There is no need to do so, and the driver's burden can be reduced when waiting for a signal. Also, if the parking brake is released and the transmission is operated in a mode other than neutral, the electromagnetic relays 6 and 11 will be de-energized and will automatically return to the original operating state, so do not forget to turn on the headlight 10 when starting. You can prevent it, and you will not run without lights.

When the wiper or headlight is not used, if the selection switch 9 is turned off, the exciting current does not flow in the electromagnetic relays 6 and 11 even if the parking brake is operated and the transmission is set to neutral, and the battery is discharged. It will not be wasted. In this embodiment, both the wiper and the headlight can be switched in operation, but it goes without saying that only one of the wiper and the headlight can be switched in operation. Further, as the vehicle stop detection condition, in the present embodiment, the operation of the parking brake and the neutral set of the transmission are used, but the condition is not limited to this.

[0021]

[Effect of the device]

 As described above, according to the present invention, the wiper and the headlight in operation can be automatically switched to the operation level which is one step lower by detecting the stop of the vehicle. The number of operations such as waiting for a signal when driving is reduced and the driver's burden can be reduced. In addition, it is possible to prevent forgetting to turn on the headlights when the vehicle starts after the vehicle has stopped, thus preventing the danger of driving without lights. In addition, since it is possible to select whether to operate the wiper or headlight operation switching control with the selection switch, this can be used when the operation switching control function is not needed because the wiper or headlight is not used. It is possible to prevent wasteful operation of the battery and prevent wasteful consumption of the battery.
