Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control system for a vehicle which permits starting of an engine or running of a vehicle only when a proper ID storage medium is used.

[0002]

In recent years, in order to improve usability or security, when an occupant carries an ID tag in which an identification code is stored and gets into a vehicle, for example, the occupant is identified from the ID tag. Read the code,
When the identification code matches a pre-registered code, a system has been considered in which the engine is permitted to be started by operating a knob operably provided by an occupant.

[0003] Therefore, the occupant can start the engine by operating the knob with the ID tag carried instead of carrying the conventional mechanical key, so that the usability is excellent.

However, in such a configuration, the operation on the knob is always possible.
If the communication with the tag is not performed normally, the engine cannot be started even if the occupant operates the knob, and the cause is not known. Further, when communication with the ID tag is performed in a state where the knob is operated to the start position, a communication abnormality may occur.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an ID storage device in a configuration in which an engine can be started or a vehicle can be driven in accordance with an operation on an operation means while a proper ID storage medium is used. It is an object of the present invention to provide a vehicle control system that can easily confirm whether communication with a medium has been normally performed and can prevent occurrence of communication abnormality.

[0006]

According to the present invention, there is provided a vehicle control system provided with a portable ID storage medium storing an identification code, and an operating means operable from a vehicle operable position to an engine start position in the vehicle. The operation means is prohibited from being operated from the vehicle running position to the engine start position, and the operation of the operation means is prohibited when the identification code read from the ID storage medium matches the one registered in advance. Operation permission means for releasing the state is provided (claim 1).

According to such a configuration, normally, the operation permission means prohibits the operation means from being operated from the vehicle travelable position to the engine start position. When the user carries the ID storage medium and gets on the board, the operation permission unit reads the identification code from the ID storage medium and determines whether the identification code is registered in advance. At this time, if the read identification code is registered in advance, the operation permission unit releases the operation prohibition state for the operation unit. Thus, the engine can be started by operating the operating means from the vehicle running position to the engine starting position.

Here, when the communication with the ID storage medium is not normally performed, the operation permission means continues the operation prohibition state for the operation means, so that the operation means is moved from the vehicle travelable position to the engine start position. It cannot be operated. Accordingly, it is possible to easily confirm that the communication with the ID storage medium is not normally performed because the operation means cannot be operated to the engine start position. Further, since communication with the ID storage medium is performed when the operation means is at the position where the vehicle can travel, communication with the ID storage medium can be reliably performed.

The vehicle control system according to the present invention further comprises a portable ID storage medium storing an identification code,
The vehicle is provided with operating means capable of operating from the vehicle travel prohibited position to the vehicle travel enabled position. The operation means is prohibited from being operated from the vehicle travel prohibited position to the vehicle travel enabled position, and is read from the ID storage medium. An operation permitting means is provided for canceling the operation prohibition state on the operation means when the identification code matches the one registered in advance (claim 2).

[0010] According to such a configuration, when the identification code stored in the ID storage medium matches the one registered in advance, the operation permission unit releases the operation prohibition state for the operation unit. The operating means can be operated from the vehicle traveling prohibited position to the vehicle traveling enabled position.

In this case, if the communication with the ID storage medium is not performed normally, the operation of the operating means from the vehicle running prohibited position to the vehicle running enabled position is prohibited. It can be confirmed that communication has not been performed normally.
