System Description: Description
WARNING: This page is about a different car, the 2018 Infiniti Q60. However, it is still accessible from the selected car via links, so may be relevant.
ECM prioritizes requests from all systems performing engine torque request and adjusts torque (according to drivability and specified priorities). In addition, ECM determines the method of satisfying each request and adjusting torque.
ECM controls torque according to the following items.
- Accelerator pedal position sensor (Accelerator pedal effort)
- EMCM (ABS operation, ESP operation, TCS operation)
- ADAS control unit (ASCD control)
- TCM (Engine speed limit signal, vehicle speed limit signal, max torque limit signal)
ECM adjusts torque according to the following controls.
- Injection time adjustment: for details, refer to System Description .
- Advance/retard angle of ignition timing adjustment (Torque varies quickly.): For details, refer to System Description .
- Synchronization of the injection and ignition order: For details, refer to System Description .
NOTE:
Extending fuel injection time and adjusting ignition timing in retard direction do not allow engine torque to be changed so soon. When ignition timing is adjusted in advance direction, engine torque can be changed soon.
