Operating Conditions: Notes
- Engine start:
The IMA system drives the IMA motor and starts the engine during normal starts and when re-starting from an idle stop.
The IMA motor is linked directly to the engine crankshaft.
- Start running:
The IMA motor assists the engine.
- Slow acceleration:
Runs only with the engine.
- Low speed cruise:
At a constant speed of about 25 mph (40 km/h) with light load, all engine cylinders are deactivated, and the vehicle runs only with the IMA motor. When the state-of-charge (SOC) drops, the engine starts and the IMA motor begins to charge the battery module.
- Acceleration:
The IMA motor assists the engine.
- High acceleration:
The IMA motor assists the engine.
- High speed cruise:
Runs only with the engine. When the state-of-charge drops, the IMA motor begins to charge the battery module.
- Deceleration:
All engine cylinders are deactivated, and the IMA motor captures the deceleration energy and charges the battery module.
- Stop:
When conditions are satisfied, the PCM stops the engine automatically (auto stop).
