VEHICLE OPERATION SYSTEM AND METHOD

摘要

A method of operating a vehicle having an engine, an engine control unit (ECU), a throttle operator, and a throttle body fluidly communicating with the engine. A throttle valve disposed in the throttle body regulates fluid flow to the engine. A throttle valve actuator is connected thereto for controlling a throttle valve position. A key receiver is configured to link to a key. The method includes linking a key to the key receiver and initiating engine operation. If the key is linked to the key receiver and engine operation has been initiated, an identification code of the key is read and an authorization status of the key is thereby determined. If the key is determined to be authorized, the throttle valve position is controlled based in part on a throttle operator position. If the key is determined to be unauthorized, the throttle valve position is limited to a security limit.

1. A method of operating a vehicle,
the vehicle comprising:
an engine;an engine control unit (ECU) controlling operation of the engine;a throttle operator operatively connected to the ECU;a throttle body fluidly communicating with the engine;a throttle valve disposed in the throttle body regulating fluid flow to the engine;a throttle valve actuator connected to the throttle valve for controlling a throttle valve position, the throttle valve actuator being in electronic communication with the ECU; anda key receiver configured to link to a key, the method comprising:
linking a key to the key receiver;initiating engine operation;if the key is linked to the key receiver and engine operation has been initiated:
reading an identification code of the key and thereby determining an authorization status of the key;if the key is determined to be an authorized key, controlling the throttle valve position based in part on a throttle operator position; andif the key is determined to be an unauthorized key, limiting the throttle valve position to be less than a security limited throttle valve position.
