Control Outline

|
Idle speed control
|
• Controls the throttle valve opening angle during idling so that the idle speed is at the target idle speed.
|
|
Accelerator control
|
• Controls the throttle valve opening angle according to the amount of AP depression. Has a fully-closed throttle learning function for consistent setting of the optimum throttle opening angle according to changes due to age deterioration.
|
|
Traction control
|
• Controls the throttle valve opening angle by torque up/down request signals from the DSC HU/CM and TCM (AT).
|
|
Cruise control
|
• Sets the vehicle speed by operation of the cruise control switch and controls the throttle valve opening angle so that it becomes close to the set vehicle speed.
