Abstract

PURPOSE:To provide excellent on-vehicle control devices in which controllers of on-vehicle equipment is automatically started and stopped concurrently with getting in and off a vehicle of a user. CONSTITUTION:An on-vehicle control device is provided with a detector 2 detecting the getting in a vehicle by a user 1, an AD converter 3 converting analogue output of the detector 2 into a digital signal, and a microcomputer 4 controlling a driver 5 operating on-vehicle equipment by output of the AD converter 3. The getting in the vehicle a user 1 causes a signal from the detector 2 to become larger than a specified and the on-vehicle equipment such as a car audio to automatically actuate to become an operation condition. Moreover, the getting off from the vehicle by the user 1 can also cause automatic stopping of the on-vehicle equipment such as the car audio due to the signal from the detector 2.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle-mounted control device used for a vehicle-mounted device or the like which operates by sensing a passenger in a tower.

[0002]

2. Description of the Related Art In a conventional on-vehicle control device, a desired operation is activated or stopped by an operation of a tower passenger. For example, the power supply of in-vehicle devices such as car audio has been turned on and off by a manual operation of a tower passenger. Also, tape, CD
Regarding the ON / OFF of the operations such as the above, or the operation of the memory SW, the respective operations can be performed by operating the operation buttons and the like provided on the display unit of the vehicle-mounted device by the tower passenger. .

[0003]

However, in the above-described conventional vehicle-mounted control device, the desired operation can be achieved only when the tower occupant operates the button.
There is a problem that the on-vehicle device cannot be automatically operated at the same time as the passenger gets into the vehicle without operating the button.

The present invention solves such a conventional problem, and when the tower passenger gets into the vehicle, the in-vehicle device is automatically activated, and when the tower passenger gets out of the vehicle, the vehicle is mounted on the vehicle. It is an object of the present invention to provide an excellent vehicle-mounted control device in which the equipment for use automatically stops.

[0005]

In order to achieve the above object, the present invention provides a detector for detecting that a tower passenger has got on a vehicle, and an AD conversion for converting an analog output of the detector into a digital signal. And a control means for controlling a driver for operating the in-vehicle device by the output of the AD converter.

[0006]

The present invention has the above-described structure, and when the tower occupant sits in the driver's seat or the passenger seat of the vehicle, the signal from the detector becomes larger than a predetermined level, and the controller of the on-vehicle equipment such as car audio is It can be automatically activated and activated. Further, when the tower passenger gets off the driver's seat or the passenger seat of the vehicle, the signal from the detector becomes smaller than a predetermined level, and the controller of the vehicle-mounted device such as a car audio can be automatically stopped.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows the configuration of an embodiment of the present invention. In FIG. 1, reference numeral 1 is a occupant of a vehicle. Reference numeral 2 is a detector composed of an optical sensor, which generates a signal when the tower occupant 1 sits in the driver's seat or the passenger seat of the vehicle. Reference numeral 3 denotes an AD converter, which converts an analog signal output generated by the detector 2 into a digital signal. Reference numeral 4 is a microcomputer, and the output of the AD converter 3 turns the driver 5 ON / O.
FF control is performed. The driver 5 can activate or deactivate a controller of an in-vehicle device (not shown) such as a car audio.

Next, the operation of the above embodiment will be described. In FIG. 1, when the occupant 1 sits in the driver's seat or the passenger seat of the vehicle, the analog signal emitted from the detector 2 becomes large, and this analog signal is converted into a digital signal by the AD converter 3. The digital signal output of the AD converter 3 is applied to the microcomputer 4. In the microcomputer 4, the driver 5 is turned on when the analog signal emitted from the detector 2 becomes large, and the driver 5 is turned off when the analog signal emitted from the detector 2 becomes small. Controlled. When the driver 5 is turned on, the controller of an in-vehicle device (not shown) such as a car audio can be activated.

FIG. 2 is a flow chart showing the flow of the control operation of the microcomputer 4. As shown in FIG. 2, when the analog signal emitted from the detector 2 is below a certain level, the driver 5 is off. When the analog signal emitted from the detector 2 exceeds a certain level, the driver 5 is turned on and a vehicle-mounted device (not shown) such as a car audio can be activated.

As described above, according to the above-mentioned embodiment, when the tower occupant sits in the driver's seat or the passenger seat of the vehicle, the controller of the vehicle-mounted device such as the car audio is automatically activated by the signal from the detector 2. Can be activated.
Further, when the passenger gets off the driver's seat or the passenger seat of the vehicle, the controller of the vehicle-mounted device such as car audio can be automatically stopped by the signal from the detector 2.

In the above embodiment, the detector 2 controls the on-vehicle equipment by detecting the presence / absence of the occupant, but detects the object other than the occupant and detects the on-vehicle equipment. It can also be controlled automatically.

[0012]

The present invention is constructed as described above, and the signal of the detector for detecting that the tower passenger has got into the vehicle is AD
When the signal is converted to a digital signal by the converter and the signal is higher than a predetermined level, the driver who operates the in-vehicle device is turned on, so that the tower occupant sits in the driver's seat or the passenger seat at the same time. Thus, there is an effect that the controller of an in-vehicle device such as a car audio system can be automatically activated and put into an operating state without a tower passenger operating a button.

Further, when the tower passenger gets out of the driver's seat or the passenger seat of the vehicle, the signal level from the detector lowers, so that the controller of the vehicle-mounted device can be automatically stopped.

Further, it is possible to detect an object other than the occupant and automatically control the on-vehicle equipment.
