Abstract

A vehicle controller for a straddle type vehicle includes a portable device that transmits a code signal and control unit comprising a receiver and an authenticator that respectively receive and authenticate the code signal. If the authentication is determined to be successful, a release signal is issued from a control unit to actuate a release structure of a steering lock to automatically release the steering lock. When a power source of the control unit is turned off, manual locking is allowed. Manual locking of the steering lock is actuated through a user'"'"'s operation of a push-type locking switch. A manual lock structure is provided to manually lock the steering lock. The manual lock structure can be integrated with the automatic release structure that automatically releases the steering lock.

Claims

1. A vehicle controller for a straddle type vehicle comprising:

a steering lock including a push-type locking element that locks a steering assembly, and

a control unit including;

a portable device, the portable device programmed to transmit a code signal,

an authenticator programmed to receive and authenticate the code signal,

a release control unit in electrical communication with the steering lock, wherein

the release control unit issues a release signal to the steering lock if the code signal is successfully authenticated,

the steering lock automatically unlocks the steering assembly in response to the release signal, and

the steering lock locks the steering assembly in response to an operation of the push-type locking element only if a power source for the control unit is turned off.

2. The vehicle controller for a straddle type vehicle according to claim 1, wherein the push-type locking element and an automatic release construction are integrated together.

3. The vehicle controller for a straddle type vehicle according to claim 1, wherein once the steering lock is automatically released, the push-type locking element is not capable of operation until the power source of the control unit is turned off.

4. The vehicle controller for a straddle type vehicle according to claim 1, wherein the code signal transmitted from the portable device is transmitted in response to a request signal transmitted in response to user'"'"'s operation of an activating switch provided in the vehicle, and wherein the activating switch is a push switch.

5. The vehicle controller for a straddle type vehicle according to claim 4, wherein the activating switch comprises a two-stage push switch and the request signal is transmitted from the vehicle in response to a first pressing operation and the power source is turned off in response to a second pressing operation.

6. A straddle type vehicle incorporating the vehicle controller for a straddle type vehicle according to anyone of claim 1.

7. A vehicle controller comprising a portable device, a control unit and a steering lock, the portable device adapted to transmit a code signal, the control unit being in electrical communication with a power source and the steering lock, the control unit comprising a receiver and an authenticator, the receiver being adapted to receive the code signal and the authenticator being adapted to confirm that the received code signal identifies an approved portable device, the control unit providing a signal to the steering lock when the code signal is successfully authenticated, the steering lock comprising a lost motion linkage and a locking pin, a portion of the locking pin being adapted for manipulation by a user, the lost motion linkage adapted to secure the locking pin in a locked position and an unlocked position so long as power is supplied by the power source and the lost motion linkage adapted to secure the locking pin in only the locked position when power is not supplied by the power source.

8. The vehicle controller of claim 7, wherein the portion of the locking pin defines a push-button at one end of the locking pin and the other pin interacts with a portion of a steering assembly of a vehicle.
