General conflict description:
Principle concept:
If manual operation of fuel-saving multi-state switch is required, then driver can control gear switching, but operation convenience deteriorates and fuel-saving effect becomes poor due to mismatched load conditions
Why choose this principle:
The system automatically detects vehicle load conditions through sensors and autonomously switches between gear states without driver intervention. The control unit processes sensor signals and actuates the multi-state switch based on real-time operating conditions, enabling the system to serve itself and eliminate manual operation requirements.
Principle concept:
If manual operation of fuel-saving multi-state switch is required, then driver can control gear switching, but operation convenience deteriorates and fuel-saving effect becomes poor due to mismatched load conditions
Why choose this principle:
The system continuously monitors vehicle operating parameters through sensors and feeds this information back to the control unit. Based on the feedback signals indicating load conditions, the control unit automatically adjusts the gear state of the multi-state switch, creating a closed-loop control system that adapts to changing operating conditions in real-time.

Abstract
A control circuit and method for a fuel-saving multi-state switch is provided. The control circuit comprises a vehicle body ECU, a fuel-saving control unit, and a PWM voltage regulating unit. The fuel-saving control unit is connected to the vehicle body ECU through a CAN bus to collect CAN signals. The fuel-saving control unit determines a switch gear required by a current vehicle according to the CAN signals and outputs a PWM pulse signal having a corresponding duty cycle. The PWM voltage regulating unit is connected to the fuel-saving control unit to receive the PWM pulse signal. The PWM voltage regulating unit outputs a voltage value corresponding to the switch gear according to the PWM pulse signal. The vehicle body ECU is connected to the PWM voltage regulating unit to receive the voltage value, so as to control a speed and torque of an engine according to the voltage value.
