Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle radio starting apparatus for starting a vehicle engine by radio.

[0002]

2. Description of the Related Art Conventionally, an ignition switch connected to a starter circuit for starting an automobile engine is increasingly integrated with a steering lock mechanism. There are many. In recent years, automobiles having a steering tilt mechanism in which the angle of a steering wheel is variable between getting on and off and driving are becoming widespread.

[0003]

Therefore, in the above-mentioned conventional automobile, if the wiring harness connecting the ignition switch and the starter circuit is not correctly routed, the wiring harness comes into contact with the steering tilt mechanism. As a result, the coating may be peeled off and short-circuited to the body.

[0004] Further, since the above-mentioned conventional ignition switch is arranged at a position where it is difficult to see from the driver's point of view, it is possible to arrange an illumination or the like so that
In some cases, the position is specified, but in that case, the number of parts is increased.

On the other hand, an engine start signal is transmitted wirelessly,
There has been proposed a remote engine start system in which the starter motor is rotated for a predetermined period upon receiving the start signal (Japanese Patent Laid-Open No. Hei 6-307316). In such a low temperature atmosphere, the engine may not start.

A remote starter has been proposed in which a start signal transmitted wirelessly from a remote place is received, the starter motor is operated, and the starter motor is stopped when the engine is started (Japanese Unexamined Patent Application Publication No. Hei 3 (1999)). -175149, JP-A-7-77141), in this case,
Since a separate determination circuit for determining the start of the engine is required, the number of circuit components is increased, and the circuit configuration is complicated.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problem, and provides a radio starting apparatus for a vehicle in which an ignition switch is abolished by enabling an engine to be started only when a driver is located in a vehicle. The purpose is to provide.

[0008]

According to the present invention, there is provided a receiving means for receiving an engine start instruction signal transmitted wirelessly, and when the engine start instruction signal is received, power is supplied from a battery to an ignition circuit and a starter circuit. A wireless starter for an automobile, comprising: a determination unit configured to determine whether a driver is located in a driver's seat; and an engine start instruction signal when the driver is determined to be located in a driver's seat. And engine start control means for supplying electric power from a battery to the starter circuit only while receiving the start signal (claim 1).

According to this configuration, when the engine start instruction signal transmitted wirelessly is received, the engine start instruction signal is received when it is determined that the driver is located in the driver's seat. By supplying power from the battery to the starter circuit that starts the engine only for a while,
The engine is surely started by the driver himself, and the driver is surely started by transmitting the engine start instruction signal while judging the engine start situation. In addition, since the existing ignition switch can be abolished, the configuration can be simplified.

The determining means determines that the driver is located in the driver's seat when the operating means operated by the driver is operated (claim 2).

According to this structure, when the operating means operated by the driver is operated, it is determined that the driver is located in the driver's seat, so that the driver is located in the driver's seat. The above-mentioned determination can be performed without separately providing a detecting means for detecting, and a complicated configuration can be avoided.

[0012] Further, in the wireless starting apparatus for an automobile according to the first or second aspect, there is provided a shift position detecting means for detecting a position of a shift lever of an automatic transmission, and the engine start control means includes a step of detecting whether the shift lever is a parking range or The power is supplied from the battery to the starter circuit only when in the neutral range.

According to this configuration, when the engine start instruction signal transmitted wirelessly is received, the shift lever is shifted to the parking range or the neutral range when it is determined that the driver is located in the driver's seat. Only when there is a certain time, the electric power is supplied from the battery to the starter circuit that starts the engine only while the engine start instruction signal is being received, so that the engine can be suitably started in the automatic transmission.

Reference numerals 85 denote push switches that are turned on only while being pressed with a required pressing force.

The transmission circuit 87 generates a transmission signal according to the operation of each of the switches 81 to 85, and outputs the generated transmission signal from the transmission antenna 86.

The receiving circuit 22 of the joint box 2
Is for demodulating the signal from the transmitter 8 received by the receiving antenna 21 and outputting the signal to the control circuit 28. The stop lamp switch 23 is linked to an unillustrated brake pedal, and is turned on when the driver depresses the brake pedal. The shift position detector 27 detects the position of the shift lever and outputs the detected position of the shift lever to the control circuit 27. In this embodiment, the vehicle is an automatic transmission vehicle.

The control circuit 28 is composed of a microcomputer or the like and controls the entire operation. When a signal indicating that the lock switch 83 of the transmitter 8 is pressed is inputted, the door lock solenoids 3 to 6 are activated. When the switch is turned on to lock the door and a signal indicating that the unlock switch 84 has been pressed is input, the door lock solenoids 3 to 6 are turned on.

[0032]

As described above, according to the present invention,
When receiving the engine start instruction signal transmitted by radio, when it is determined that the driver is located in the driver's seat,
The power is supplied from the battery to the starter circuit that starts the engine only while the engine start instruction signal is being received, so that the driver can surely start the engine by himself and the driver can start the engine in the engine start condition. The engine start instruction signal can be transmitted while judging the condition, so that the engine can be started reliably. In addition, the existing ignition switch can be eliminated, and this eliminates the need for wiring work of the wire harness connected to the ignition switch, thereby simplifying the manufacturing process.

Further, when the operating means operated by the driver is operated, it is determined that the driver is located in the driver's seat, thereby detecting that the driver is located in the driver's seat. The above determination can be performed by using the existing operation means without separately providing the detection means of
The complication of the configuration can be avoided.

When an engine start instruction signal transmitted by radio is received, when the driver is determined to be located in the driver's seat, only when the shift lever is in the parking range or the neutral range. By supplying power from a battery to a starter circuit that starts the engine only while the engine start instruction signal is being received, it is possible to preferably start the engine in the automatic transmission.
