Start-stop control system and start-stop controller for stepless variable-speed EFI (electronic fuel injection) motor vehicles

Abstract

The invention discloses a start-stop control system for stepless variable-speed EFI (electronic fuel injection) motor vehicles. The start-stop control system controls the start of a starter, controls a fuel injector to carry out fuel injection, and controls the turning-on of an indicating lamp according to the states of start-stop main switches, position signals of a throttle, vehicle speed signals, engine speed signals, brake status signals and battery power signals, so that when a stepless variable-speed EFI motor vehicle is running at an idle speed, the fuel injector can automatically stop fuel injection so as to close down an engine, in such a way, the stepless variable-speed EFI motor vehicle can be in a flame-out and sliding state at an idle speed, thereby reducing the fuel consumption; and after the flame-out of the engine, when the vehicle is required to be started, the engine can be re-started just through pinching a brake or pulling an accelerator, therefore, the operation is simple. The invention also discloses a start-stop controller for the stepless variable-speed EFI motor vehicles.

Description

technical field [0001] The application relates to a motor vehicle, in particular to a start-stop control system and a start-stop controller for a continuously variable speed electronic injection motor vehicle. Background technique [0002] CVT (Continuous Variable Transmission, continuously variable transmission) transmission, also known as continuously variable transmission or continuously variable transmission. The biggest difference between this kind of transmission and ordinary automatic transmission is that it saves the complicated and cumbersome gear combination speed change transmission, but only uses two sets of pulleys for speed change transmission, and changes the speed by changing the contact radius between the driving wheel and the driven wheel drive belt. . CVT (Continuous Variable Transmission, continuously variable transmission) transmission is widely used in EFI engine motorcycles and small displacement, low power EFI engine vehicles. [0003] The EFI engin...

AI Technical Summary

Problems solved by technology

[0004] Common continuously variable speed electronic fuel injection motor vehicles consume fuel and emit harmful gases in each working condition. When the vehicle is idling, the vehicle does not perform external work, but the engine still runs and produces exhaust emissions and consumes fuel.

In order to save fuel, the driver needs to turn off the flameout switch to stop the engine. When starting, turn on the flameout switch and re-trigger the electronic ignition button to start the engine. The operation is troublesome.
