Logic Flow Chart
Check Conditions
- When the driving mode is the series driving mode
- When the cold strategy idle control status is ON
- At the time of state with more than 7°C (45°F) Celsius of temperature of engine coolant at the time of the engine start.
- At the time of state with less than 42°C (108°F) Celsius of temperature of engine coolant at the time of the engine start.
Judgment Criterion
- When the target rotation speed of the generator is larger than 540 r/min (the target rotation speed of the engine is larger than 200 r/min), and when a state where the engine torque correction amount is within the specified range continues for 20 seconds.
- When a state where the target rotation speed of the generator is less than -270 r/min (the target rotation speed of the engine is less than -100 r/min) continues for 20 seconds.
