Electronic Control Unit (ECU)
An Electronic Control Unit (ECU) for trucks and trailers is a microprocessor-based device that manages and coordinates various electronic systems within the vehicle. Essentially, it acts as the brain of the truck or trailer, constantly reading data from different sensors and inputs to control and optimize the vehicle’s performance.
Key Functions of an ECU in Trucks and Trailers
- Engine Control: Manages fuel injection, ignition timing, and air-fuel mixture to ensure optimal engine performance and efficiency.
- Transmission Control: Oversees the transmission system, ensuring smooth gear shifts and optimal gear ratios.
- Brake Control: Manages the anti-lock braking system (ABS) to prevent wheel lock-up and maintain traction during braking.
Stability Control: Helps maintain vehicle stability by adjusting braking and engine power based on sensor inputs. - Body Control: Controls various electrical systems such as lighting, power windows, and door locks.
