Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control device capable of remotely controlling an engine of an automobile.

[0002]

2. Description of the Related Art In a turbo car, if the engine is stopped immediately after high-speed running, etc., there is a risk that the turbine shaft may seize and malfunction.
Minutes), it is customary to perform after-idling. A device that automatically performs this operation is a so-called turbo timer. After the ignition key is turned from the ON position to the OFF position and the key is removed, after idling is performed for a set time (for example, 5 minutes).

[0003] The turbo timer includes a manual system and an automatic system. In the manual system, the after-idling time is set by a changeover switch provided on the vehicle-mounted device. In the auto mode, the after idling time is automatically set based on the running time, the engine speed, and the like. In general, if the running time is long, the after-idling time is set long, and if the running time is short, the after-idling time is set short.

[0004] If a turbo timer is mounted, the user can get off the vehicle after stopping driving, lock the door, and immediately leave the vehicle. There is also a usage method in which the air conditioner is turned on during a short time (several minutes to several tens of minutes) such as when using a public telephone or shopping at a convenience store, so that the comfort at the time of re-riding is not impaired.

Some remote control devices for starting and stopping the engine wirelessly include the above-mentioned turbo timer function.

[0006]

The conventional remote control device equipped with the turbo timer function has the following problems. (A) Since the in-vehicle device of the remote control device does not degrade the aesthetics in the vehicle (wiring cords are required), it is generally arranged in a place invisible to the occupants, so a changeover switch for setting the after-idling time It is difficult to operate even if is attached to the on-board unit (not used).

[0007] (i) Since the portable device is not provided with a switch for extending the after-idling time, the after-idling time cannot be extended even if the getting-off time (shopping at a convenience store or using a public telephone) is longer than expected. Therefore, the air conditioner stops at the end of after-idling, and the temperature inside the vehicle rises (summer) or falls (winter).

An object of the present invention is to provide a highly convenient remote control device capable of extending an after-idling time by a portable device.

[0009]

The portable device 5 further includes an oscillation circuit for generating a carrier wave, a modulation circuit for applying MSK modulation to the carrier wave, and a lithium battery (6 V) as an operation power supply. The modulation circuit superimposes a start command signal (or a time extension command signal) and a stop command signal on a carrier wave based on a pressing operation of the start switch 1 and the stop switch 2.

The receiving antenna 6 is a whip antenna that is attached to a base fixed in the vehicle compartment so as to be tiltable, and a signal is transmitted to the vehicle-mounted device 12 via a coaxial cable. The receiving means 7 and the analyzing means 8 demodulate command signals (start command signal, time extension command signal, stop command signal) from the signal captured by the receiving antenna 6.

The relay circuit 9 includes a first relay for bypassing between the COM contact 14 and the ACC contact 15 of the ignition switch 13, a second relay for bypassing between the COM contact 14 and the IG contact 16, and a COM relay 14-. It is configured by a third relay that bypasses between the ST contacts 17, a transistor that drives each relay, and the like.

Next, the operation of the remote control engine starter A in after-idling will be described with reference to FIG. When the ignition switch 13 has been switched from the ON position to the OFF position through the ACC position in step s1 while the engine is operating (by manual start using the ignition key), and the switch to the OFF position is detected (step s1). (YES), the process proceeds to step s2.

At step s2, the control means 10 controls the relay circuit 9, switches the ACC relay and the IG relay to the ON state, and starts after-idling. In step s3, it is determined whether or not a time extension command signal has been input, and if the input of the time extension command signal is detected (YES), the process proceeds to step s4, and if not detected (NO), step s6.
Proceed to.

In step s4, it is determined whether or not the input of the time extension command signal has been detected for the first time. If it is the first time (YES), the process proceeds to step s5, and if it is the second or subsequent time (NO). Goes to step 6.

In step s5, the after-idling time is extended to the remaining initial setting time (initial value: 3 minutes) + the additional setting time, and the flow advances to step s6. The additional setting time (2 minutes, 12 minutes, 17 minutes, 27 minutes) is determined by the setting state of the time setting switch 11 and the time setting switch 3.

In step s6, it is determined whether or not the after-idling time has expired.
O) proceeds to step s7, and if completed (YES), proceeds to step s8.

In step s7, it is determined whether or not a stop command signal has been input, and the input of the stop command signal is detected (YES).
Proceeds to step s8, and if not detected (NO), returns to step s3.
