2. CONFIGURATION
1) Circuit Diagram
The engine ECU detects the operating conditions of cruise control system, and monitors the braking
performance, vehicle speed, road conditions and ESP system operation. If the engine ECU determines
that there are not any problem to drive in cruise control mode, the vehicle can be operated by cruise
switch signals (decelerating, accelerating, cruising).

2. OPERATING PROCESS
System diagram ▶
Operation ▶
EEM monitors the electric loads and battery conditions and controls the voltage to improve the fuel
economy and battery charging efficiency.
EBS on “-“ terminal of battery sends the battery information (voltage, current, tem
perature and
SOC) to engine ECU with LIN communication.
Engine ECU outputs the information from EBS and regulating control signal (PWM) according to the

Engine ECU controls the magnetic resistance between stator coil and rotor coil by controlling the
current in rotor coil according to PWM duty value.
The alternating voltage induced to stator coil is converted to direct voltage by rectifier. And, EBS
