Description

How to determine whether to terminate the idle stop function

The present invention relates to a method for determining whether to terminate an idle shutdown function, and more particularly to a method for determining whether to terminate an idle shutdown function for a fuel vehicle.

Existing vehicles with an idle shutdown function must meet the following conditions before they can automatically shut down, such as the engine is in a hot state (e.g., engine temperature > 70 degrees); the throttle opening is in an idle state (e.g., throttle opening < 4 degrees); the engine speed is in an idle state (e.g., engine speed < 2400 rpm); the battery is in a normal state (e.g., voltage > 12 volts when idling); and the vehicle speed is in a stationary state (e.g., vehicle speed < 5km/h). In addition, the vehicle can automatically start after automatically shutting down if the following conditions are met, such as opening the throttle. When you want to start again, turn the throttle and the engine restarts, allowing the continuously variable transmission mechanism to transmit power to the rear wheels. Therefore, compared with traditional vehicles that do not shut down when idling, the engine has a time difference because it needs to be restarted.

Furthermore, in actual road conditions, in addition to slowing down and stopping when driving straight, there are also situations such as waiting to turn or make a turn. When waiting to turn or make a turn, the time difference in restarting the engine will cause riders to complain about the vehicle's slow response when starting.

The inventor, in order to provide the rider with a better experience when waiting to turn or turn, based on the spirit of active invention, has been eager to think of a method for determining the termination of the idling shutdown function that can solve the above problem. After several years of research and experiments, the present invention is finally completed.

The main purpose of the present invention is to provide a method for determining the termination of the idle shutdown function. The method can be used to optimize the control logic of the idle shutdown function, improve the slow response of the motorcycle, and provide a better user experience.

To achieve the above-mentioned purpose, the method for determining the termination of the idle shutdown function of the present invention is used on a motorcycle, which includes an engine, an engine control unit, an instrument, a turn signal switch and a turn signal. The engine control unit is electrically connected to the engine to control the engine's operating state and determine whether to terminate the engine's idle shutdown function; the engine control unit is electrically connected or communicatively connected to the instrument to receive a physical or electronic signal from the instrument; the instrument is electrically connected to the turn signal switch to receive a switch signal from the turn signal switch; the turn signal switch is electrically connected to the turn signal to turn the turn signal on or off; wherein, the method for determining the termination of the idle shutdown function includes the following steps: (A) The rider operates the turn signal switch to turn on the turn signal and executes step (B); (B) Determine whether the engine is running, if so, execute step (C), if not, execute step (D); (C) Terminate the engine's idle shutdown function and execute step (E); (D) Restart the engine, terminate the engine's idle shutdown function, and execute step (E); (E) The rider operates the turn signal switch to turn off the turn signal and executes step (F); and (F) Activate the engine's idle shutdown function.

If the engine control unit is connected to the instrument via a communication interface, the communication interface may be a controller area network (CAN-bus), a K-line communication (KLINE), a local area network (LINBUS) or a combination thereof.

The above summary and the following detailed description are exemplary in nature and are intended to further illustrate the scope of the patent application of the present invention. Other purposes and advantages of the present invention will be described in the subsequent description and illustrations.

Please refer to FIG. 1, which is a system architecture diagram of a motorcycle of the first embodiment of the present invention. As shown in the figure, the method for determining the termination of the idle shutdown function of the present embodiment is used on a motorcycle 1, and the motorcycle 1 includes an engine 2, an engine control unit 3, an instrument 4, a turn signal switch 5, and a turn signal 6, wherein the engine control unit 3 is electrically connected to the engine 2 to control the operating state of the engine 2 and determine whether to terminate the idle shutdown function of the engine 2. The engine control unit 3 is electrically connected to the instrument 4 via a physical line a to receive a physical signal from the instrument 4. The instrument 4 is electrically connected to the turn signal switch 5 to receive a switch signal from the turn signal switch 5. The turn signal switch 5 is electrically connected to the turn signal 6 for turning the turn signal 6 on or off.

Please refer to FIG. 2, which is a system architecture diagram of a motorcycle of the second embodiment of the present invention. The difference between the motorcycle 1' of this embodiment and the motorcycle 1 of the first embodiment is that the engine control unit 3 of this embodiment is connected to the instrument 4 through a communication interface b to receive the electronic signal from the instrument 4. In this embodiment, the communication interface b is a controller area network (CAN-bus), K-line communication (KLINE), local area network (LINBUS) or a combination thereof.

Please refer to FIG. 1 to FIG. 3 together. FIG. 3 is a flow chart of a method for determining the termination of the idle shutdown function of a motorcycle in the first embodiment or the second embodiment of the present invention. As shown in the figure, the method for determining the termination of the idle shutdown function of the present invention includes the following steps: (A) the rider operates the turn signal switch 5 to turn on the turn signal 6, and executes step (B), at which time the rider is waiting to turn or turn; (B) determining whether the engine 2 is in a running state, if so, executing step (C), if not, executing step (D), so as to determine whether the engine 2 is in a shutdown state or in a running state due to the activation of the idle shutdown function; (C) terminating the idle shutdown function of the engine 2, and executing step (E), so that the engine 2 remains in a running state, thereby improving the motorcycle 1, 1'; (D) restarting the engine 2 and terminating the idling stop function of the engine 2, and executing step (E) to keep the engine 2 in operation to improve the sluggish reaction of the motorcycle 1, 1'; (E) the rider operates the turn signal switch 5 to turn off the turn signal 6, and executes step (F), at which time the rider has completed the turn or the rotation; and (F) starting the idling stop function of the engine 2. Since the motorcycle 1, 1' has completed the turn or the rotation, the idling stop function can be started again.

Through the above design, the determination method for terminating the idle shutdown function of the present invention can optimize the control logic of the idle shutdown function, improve the slow response of the motorcycle, and make it have a better user experience.

The above embodiments are merely examples for the convenience of explanation. The scope of rights claimed by the present invention should be based on the scope of the patent application, and is not limited to the above embodiments.
