Abstract

PROBLEM TO BE SOLVED: To change arbitrarily a predetermined car speed of a car speed sensitive door lock by storing the car speed when a door lock switch is depressed to a lock side at a car speed which exceeds a specified speed. SOLUTION: When a car speed ranges from 0 to 5km/h, a door lock switch 4 is depressed to a lock side, thereby operating a door lock motor 8 to lock and depressed to an unlock side, thereby operating the motor 8 to unlock. When a door lock switch 4 is depressed to the lock side at a favorite speed, the door lock motor 8 acts to lock while this speed V0 is stored in an IC of a door lock motor drive controller 1, thereby changing setting of the operation of a car speed sensitive door lock. When the car speed exceeds 5km/h, if the door lock switch 4 is depressed to the unlock side, the car speed sensitive operation will be canceled.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle speed sensitive vehicle door lock motor control device for locking a door lock motor when the vehicle speed exceeds a required speed.
The required speed can be set arbitrarily.

[0002]

2. Description of the Related Art A vehicle door lock system drives a door lock motor by a door lock knob, a door lock switch, a wireless remote control switch, a vehicle speed pulse or the like to perform a locking or unlocking operation.

A vehicle speed sensitive door lock motor control device that performs the above-mentioned locking operation by the vehicle speed pulse is, for example, as disclosed in Japanese Utility Model Laid-Open No. 3-43021, this device locks the vehicle speed pulse. The door drive motor is input to the motor drive controller to detect the vehicle speed, and when the vehicle speed exceeds the required speed, the door lock motor drive controller locks the door lock motor.

[0004]

In this vehicle speed sensitive door lock motor control device, even if the vehicle speed becomes less than or equal to the above required speed, the lock release operation is not performed for safety reasons. It is necessary to unlock the door with the door lock switch. Also, the required speed (vehicle speed) at which the door lock operation is performed
The manufacturer set a constant speed (for example, 30 km / h), and it was impossible for the user (driver) to set an arbitrary vehicle speed.

For this reason, the door is locked regardless of the driver's intention, or the door is locked even if the vehicle travels only a short distance and the speed is about 40 km / h at most. There was a case where I felt inconvenience because I had to always perform an unlocking operation when getting off.

For example, when a child is on board, it may be desired to lock the door immediately after starting for safety, even at a vehicle speed of, for example, 10 km / h.

As described above, when the door lock operation is automatically performed when the vehicle speed reaches a predetermined value, the speed at which the door lock is applied varies depending on the driver's preference and circumstances.

In view of the above situation, it is an object of the present invention to provide a door lock motor control device in which the vehicle speed at which the door lock is applied is left to the driver's intention.

[0009]

In order to solve the above-mentioned problems, according to the invention of claim 1, in the above-mentioned vehicle speed-sensitive type door lock motor control device for a vehicle, the driver arbitrarily sets the required speed. I got it.

According to a second aspect of the present invention, which is an aspect of the above-mentioned predetermined speed setting means, the door lock switch operates a door lock motor to lock or unlock the door. In the vehicle door lock motor control device for a vehicle, when the door lock switch is operated at a vehicle speed equal to or higher than a certain speed, the vehicle speed at the time of operation is set to the required speed without performing the door lock and unlocking operations. When the setting or cancellation of the setting is performed and the door lock switch is operated at a vehicle speed lower than the certain speed, the door lock or the cancellation operation thereof is performed without performing the required speed setting and the setting cancellation operation. It was.

According to a third aspect of the present invention, in the vehicle door lock motor control device according to the second aspect, the door lock switch has two contacts, a lock and an unlock. The door lock and the required speed are set by the signal from the lock side contact, and the door lock and the required speed are released by the signal from the unlock side contact of the door lock switch. .

According to a fourth aspect of the present invention, in the vehicle door lock motor control device according to the second aspect, the door lock switch is one push-type contact, and the door lock switch is operated within a predetermined time. When pressed once, the door lock and the required speed are set by the signal from the contact, and when the door lock switch is pressed twice within a certain time, the signal from the contact releases the door lock and The setting of the required speed is canceled.

[0013]

BEST MODE FOR CARRYING OUT THE INVENTION A door lock switch 4 is shown in FIG.
But lock (LOCK) and unlock (UNLOCK)
The door lock motor drive controller 1 includes a vehicle speed pulse 2, a lock signal and an unlock signal from the wireless door lock unit 3, a lock signal and an unlock signal from the door lock switch 4, A signal from the door lock motor switch 5 indicating the locked / unlocked state of the door lock motor 8, a signal from the front right (FR) door switch 6, a front left (FL), a rear right (RR), and a rear left (RL). A signal from each door switch 7 is input, and a drive signal is output to each door lock motor 8. When the door lock motor switch 5 is turned on, it becomes a lock state signal.

The door lock motor drive controller 1 operates as shown in FIG. 2 and Table 1. In the initial state, the lock operation speed of the vehicle speed door lock (lock vehicle speed V ₀ ) is, for example, 30 km.
Set to / h. In this state, vehicle speed: 0-5km /
When the value is less than h, the door lock switch 4 is pushed to the lock side (LOCK SW: ON) to lock all the door lock motors 8 to lock the doors, while the door lock switch 4 is unlocked. The unlock operation is performed by pushing it to the lock side (UNLOCK SW: ON).

Next, when the vehicle speed is 5 km / h or more and the driver pushes the door lock switch 4 to the lock side at a desired speed, the door lock motor 8 is locked unless the door is locked. At the same time, the vehicle speed sensitive door lock is set to operate at the current speed.
That is, if it is pressed at 40 km / h, the lock speed V ₀ is 4
It becomes 0 km / h. On the other hand, when the vehicle speed sensitive door lock is not desired to be set, when the vehicle speed is 5 km / h or more, when the door lock switch 4 is pushed to the unlock side, the door lock motor 8 is unlocked and the vehicle speed is increased. The sensitive door lock operation is released.

[0016]

[Table 1]

The presence or absence of the vehicle speed sensitive door lock and the lock speed V ₀ are determined by the IC of the door lock motor drive controller 1.
Is written and stored in the RAM, and from the next time, the operation is performed according to the stored content. At this time, if the RAM is used, the controller 1 must always be supplied with power, and the dark current increases. Therefore, the external EEPROM 9 can be used instead of the RAM.

3 and 4 show the door lock switch 4 having a push-type one contact, and the same reference numerals as those in FIG. This door lock motor drive controller 1 is shown in Table 2,
The operation is as shown in FIG. 4, and in the initial state, the vehicle speed lock speed V
₀ is set to 30 km / h. In this state, vehicle speed:
If the speed is less than 0 to 5 km / h, the door lock switch 4 is pressed as in the conventional case, and the next operation in the pressed state is performed. For example, in the locked state, the unlocked state is set. If the button is pressed twice, two operations are performed and the pressed state is restored. For example, if the initial state is the locked state, the state is returned to the unlocked state at the first time and to the locked state at the second time.

Next, when the vehicle speed is 5 km / h or more and the driver presses the door lock switch 4 once at a desired speed, the vehicle speed sensitive door lock operation is changed at the speed at that time. . At this time, if the door lock motor 8 is in the locked state (when the vehicle speed is 30 km / h or more), the door lock motor 8 is not driven (the drive signal is not issued) and is in the unlocked state. (Vehicle speed is 30
If less than km / h), the door lock motor 8 is driven (lock signal is output) to lock the door.

On the other hand, when it is not desired to set the vehicle speed sensitive door lock operation, when the vehicle speed is 5 km / h or more, the door lock switch 4 is turned twice twice within a certain time T (during the timer), for example, within 1 second. When pressed, the vehicle speed sensitive door lock operation is released. At this time, if in the locked state, the first pressing operation is ignored, and by the second pressing operation, the door lock motor 8 performs the unlocking operation. In the unlocked state, both pressing operations are ignored. , The door lock motor 8 is not driven.

[0021]

[Table 2]

Also in this embodiment, similarly to the above, settings such as the lock speed V ₀ are written and stored, and from the next time,
The operation is performed according to the stored contents, and the EEPROM
9 can also be used.

In both embodiments, the vehicle speed lock speed V ₀ in the initial state is not limited to 30 km / h, and the settable speed of the vehicle speed lock speed V ₀ is not limited to 5 km / h. It goes without saying that it can be appropriately selected as 4 km / h, 10 km / h, or the like. Further, the twice pressing time (constant time T) of the door lock switch 4 is not limited to 1 second, but may be appropriately selected to be 1.5 seconds or the like.

When it is desired to reset the lock speed V ₀ ,
If the above operation is repeated, it is updated and reset by that operation, and that state is held until the next setting is made.

[0025]

The present invention is configured as described above.
Depending on the driver's intention, the vehicle speed door lock operation can be released, and the locked vehicle speed can be set arbitrarily.

Further, if the setting is released by operating the door lock switch, it is possible to set the door lock operation vehicle speed according to the driver's preference without adding a special switch. It is very convenient.
