The idle start-stop function switch 2 is used for turning on or off the idle start-stop control function. When the idle speed start-stop function switch 2 is closed, a high-level signal is output, and the engine idle speed start-stop control module 1 judges that the current idle speed start-stop function is opened according to the idle speed start-stop function switch high-level signal and allows idle speed start-stop control related functions to be performed. When the idle speed start-stop function switch 2 is turned off, a low-level signal is output, and the engine idle speed start-stop control module 1 judges that the current idle speed start-stop function is turned off according to the idle speed start-stop function switch low-level signal and does not allow idle speed start-stop control related functions.
The seat belt switch 3 is used to determine whether the driver is wearing a seat belt. When the driver wears the seatbelt, the seatbelt switch 3 outputs a low level signal, and the engine idle start-stop control module 1 determines that the current seatbelt is worn based on the seatbelt switch low level signal.

The accelerator pedal sensor 6 is configured to transmit an accelerator pedal opening signal, determine whether the driver has an intention to accelerate, and determine that the driver has no intention to accelerate when the accelerator pedal opening is 0.
The instrument 5 is used for receiving related prompt or stop prompt instructions sent by the engine idle speed start-stop control module 1 and displaying corresponding prompt contents according to the instructions.
