Abstract

PROBLEM TO BE SOLVED: To obtain a transmitter that controls remotely a different on-vehicle equipment depending on a position of an antenna with an operation key by providing a position detection means of a movable antenna of the transmitter controlling remotely the onvehicle equipment. SOLUTION: Operation on/off keys are provided to a transmitter 1 and a telescopic antenna 4 extended/contained from/to a case of the transmitter 1 is provided. A position switch 5 of the antenna 4 consisting of a limit switch in cooperation with a dog 5a provided to a base end of the antenna 4 is provided and the position switch 5 is used to discriminate the extended/contained state of the antenna 4. A transmission frequency from the transmitter 1 is selected depending on a signal from the position switch 5. When the antenna 4 is in the contained state, a keyless entry system 6 is locked/unlocked by the operation of the operation buttons 2, 3 and the operation of other on-vehicle equipment 7 such as the engine starter system is controlled by the operation buttons 2, 3 while the antenna 4 is pulled out.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a remote control device for a vehicle.

[0002]

2. Description of the Related Art Conventionally, a keyless entry system and a remote control type engine starter system have been known as remote control devices for vehicles.
Further, in an electric vehicle, the compressor of the air conditioner is driven by a motor different from the drive motor for traveling, so the air conditioner may be remotely controllable.

When a plurality of remotely controllable devices are mounted on a vehicle, conventionally, a transmitter dedicated to each device is provided, or the same transmitter is provided with operation buttons dedicated to each device.

[0004]

If the transmitters dedicated to the respective devices are provided as described above, the number of transmitters increases and the storage becomes troublesome, and the transmitters are provided with operation buttons dedicated to the respective devices. In addition, the number of operation buttons increases, the transmitter becomes large, and it becomes inconvenient to carry.

In view of the above points, the present invention provides a remote control device for a vehicle, which is a common transmitter and is capable of remotely controlling a plurality of vehicle-mounted devices without increasing the size of the transmitter. It is an issue.

[0006]

[Means for Solving the Problems] In order to solve the above problems,
According to the present invention, a transmitter that remotely controls an in-vehicle device is provided with a detection unit that detects the position of a movable antenna provided in the transmitter, and the same operation button provided in the transmitter causes a difference depending on the position of the antenna. In-vehicle equipment can be controlled remotely.

According to the present invention, by changing the position of the antenna, the operation buttons can be selectively used for each in-vehicle device. Therefore, it becomes possible to remotely control multiple in-vehicle devices with a common transmitter without increasing the size of the transmitter.
It is convenient to store and carry.

By the way, the door is locked and unlocked by the keyless entry system when the driver gets on and off the vehicle. Since the transmitter is operated very close to the vehicle, the keyless entry can be performed even when the antenna is immersed. You can control the system remotely.
Therefore, when the antenna is in the immersive position, the keyless entry system can be remotely controlled with the operation button, and when the antenna is in the withdrawn position, the operation button can be used with an in-vehicle device different from the keyless entry system, such as a remote control engine starter system or It is rational to enable remote control of a remote control air conditioner.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1, reference numeral 1 denotes a transmitter of a remote control device for a vehicle. The transmitter 1 is provided with an on button 2 and an off button 3 which are operation buttons. In addition, a slide type antenna 4 is provided that can be retracted from the body of the transmitter 1.

Further, a dog 5a provided at the base end of the antenna 4
The position switch 5 of the antenna 4 which is a limit switch cooperating with the antenna 4 is provided so that the position switch 5 can determine whether the antenna 4 is pulled out or retracted.

Then, when the transmission frequency from the transmitter 1 is switched according to the signal from the position switch 5 and the antenna 4 is set to the retracted position as shown in FIG. 2 (A), the ON / OFF buttons 2 and 3 are pressed. When the keyless entry system 6 is locked and unlocked by the operation and the antenna 4 is set to the withdrawal position shown in FIG.
Other vehicle-mounted devices 7 such as a remote control type engine starter system and a remote control type air conditioner can be turned on and off by the operation.

Although the slide type antenna 4 is used in the above embodiment, a retractable type antenna 4 as shown in FIG. 3 may be used. In this case, the antenna 4 rotates integrally with the antenna 4. Form a groove 5b on the peripheral surface of the hinge portion 4a at the base end,
The position switch 5, which is a limit switch that cooperates with the groove 5b, determines whether the antenna 4 is pulled out or retracted, and the ON / OFF buttons 2, 3 are selected in the same manner as described above according to the result of the determination.
Switch the in-vehicle device to be remotely controlled with.

The present invention can also be applied to the case where a telescopic antenna is used.
