DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a remote control device for a vehicle according to the present invention, as shown in FIG. 1, is a portable terminal A for transmitting various control commands for wireless remote control using radio waves or infrared rays as a medium, and receiving the control commands. And a control drive device B on the vehicle side for appropriately opening and closing the door and starting the engine and the air conditioner.

As the portable terminal A, a push button switch 1 for opening the door and a push button switch 2 for closing the door, a push button switch 3 for instructing movement detection, and the portable terminal A while the push button switch 3 is being pressed. According to the output signal of the motion detection unit 4 which detects the motion of itself by the acceleration sensor and the acceleration sensor sent from the motion detection unit 4, the detected motion pattern is analyzed, and the analyzed motion pattern And a pattern recognition unit 5 that outputs a signal of a predetermined operation command according to the recognition result, and a predetermined control command corresponding to the signal of the operation command based on the recognition result of the movement pattern, Control command generation for generating a control command for opening or closing the door in response to an operation command when the push button switch 1 for opening the door or the push button switch 2 for closing the door is pressed 6, is constituted by a transmitting unit 7 for transmitting the control command that has been generated.

The pattern recognition section 5 stores in advance data of each reference pattern of the movement of the mobile terminal A itself.

For example, FIG. 2 shows a reference pattern corresponding to a control command for starting the engine. 3 shows a reference pattern corresponding to an air conditioner on control command, and FIG. 4 shows a reference pattern corresponding to an air conditioner off control command.

Incidentally, here, a push button switch 1 for opening the door, a push button switch 2 for closing the door, and a control command generating section 6 are provided.
A normal keyless entry system is configured by the transmitting section 7.

The portable terminal A is incorporated in a key holder 11, for example, as shown in FIG. It goes without saying that it may be incorporated in the car key 10 itself.

Further, as the control drive unit B on the vehicle side,
The receiving unit 8 that receives the control command transmitted from the mobile terminal A, and according to the content of the received control command, opens and closes the door, starts and stops the engine, and turns on the air conditioner. Various drive units 101 to 1 for turning off or the like
It is composed of a control section 9 for appropriately controlling the drive of 0n.

In the case of the above-mentioned structure, when starting the engine by remote control,
The user moves the mobile terminal A so as to draw an S-shape while pressing the push button switch 3 for instructing the motion detection.

The movement of the portable terminal A at that time is detected by the acceleration sensor of the movement detecting section 4. At that time, when an acceleration sensor having a two-axis configuration of X and Y is used,
Output signals as shown in FIG. 6 are obtained from the X axis and the Y axis. In the figure, T is a motion detection period defined by the pressing operation of the push button switch 3 for motion detection instruction.

The output signals of the respective axes of the acceleration sensor are given to the pattern recognition section 5. So, X axis, Y
By integrating each time-series signal of the axis twice, the mobile terminal A
The analysis of the movement pattern is performed.

At this time, if an acceleration sensor having a three-axis configuration of X, Y, and Z is used, it becomes possible to more sufficiently diversify the pattern that can be recognized by the output signal.

Then, the analyzed motion pattern is compared with each of the reference patterns stored in advance, and the patterns are recognized by matching with a threshold value of similarity or higher. Here, it is recognized that the movement pattern of the mobile terminal A at that time is S-shaped.

A conventional pattern recognition technique is applied as the data processing for the pattern recognition.

A signal of a predetermined operation command based on the recognition result of the pattern output from the pattern recognition unit 5 is given to the control command generation unit 6, where it corresponds to the motion pattern "S" recognized at that time. An engine start control command is generated.

Then, the control command for starting the engine is transmitted from the transmitting unit 7 to start the engine.

In this embodiment, in order to clearly distinguish when the user is moving the portable terminal A with the intention of giving some operation command and when it is not, while the push button switch 3 for motion detection instruction is being pressed. The movement of the mobile terminal A is detected from the output signal of the acceleration sensor in the movement detector 4. However, if the process for detecting the motion intended by the user is enhanced so as to be distinguished from the motion of the mobile terminal A when it is not, it is not necessary to provide the push button switch 3 for motion detection instruction.

Further, here, the push button switch 1 for opening the door and the push button switch 2 for closing the door are provided exclusively, and the control command generating section 6 is provided in response to an operation command when the push button switch 1 is pressed.
In the above, the control command for opening or closing the door is generated, but in this case, of course, the opening and closing of the door are defined by different movement patterns, and the operation command is given by the movement of the mobile terminal A. It is possible to give. In this case, the push button switch 1 for opening the door and the push button switch 2 for closing the door are unnecessary.

As described above, according to the remote control device for a vehicle of the present invention, the number of sensors is increased or a special sensor is used to increase the remote control function of the portable terminal A. Without expanding the configuration of A, a simple configuration that always uses only one acceleration sensor that detects the movement of the mobile terminal A itself makes it possible to accurately classify various types of operation commands. .

Further, according to the present invention, the mobile terminal A can be diversified by expanding the data of the motion reference pattern stored in the pattern recognition unit 5 without changing the configuration of the mobile terminal A. Become.

[0028]

As described above, the remote control device for a vehicle according to the present invention uses a wireless communication means to give a control command from a portable terminal outside the vehicle to remotely control an in-vehicle device, and the portable terminal responds to a user's operation command. Since it detects the movement of itself and issues a predetermined control command according to the movement of the mobile terminal at that time based on the result of the pattern recognition of the movement, it is possible to accurately control various types of operation commands with a simple configuration. There is an advantage that it can be properly separated and various remote operations can be reliably performed.

Further, according to the present invention, it is possible to easily extend the remote operation by the portable terminal by additionally storing the reference pattern data so that the movement pattern of the portable terminal can be recognized without changing the configuration.
