FI-ECU
The ECU controls overall power train including the ignition system, the fuel system, and the transmission for the purpose of engine performance improvement, fuel consumption improvement, cleaner exhaust gas, and drivability improvement. In case of hybrid vehicle products, it also perform controls exclusive to hybrid vehicles additional to the above controls.
ECU for Active Control Mount
ACM (Active Control Mount) restrains the vibration conducted to the vehicle body by offsetting vibration caused by variable cylinder management of the engine for the reduction of the exhaust gas and better fuel consumption with the vibration of the opposite phase at the minimal level. This controls the actuator that is built into the ACM depending on the situation.
ECU for AWD
This is an electric control unit that controls the switching between 2-wheel drive and 4-wheel drive by distribution of driving force of the front wheels and rear wheels responding to the changes of the road surface conditions and the vehicle running conditions at real-time, and also controls the function of LSD (Limited Step Differential) function, which stabilizes the driving force of left and right rear wheels.
SRS Unit Sensor
As a passenger protection device to assist seat belt, accelerator sensor reacts when a vehicle has a collision. Information about the acceleration is sent from the sensor to SRS (Supplemental Restraint System). SRS is an electronic control unit that takes the information from the accelerator sensor inside of SRS unit and controls the air bags for the driver seat, passenger seat, and rear seats, and the pre-tensioner that rolls up the seat belt.
