Cruise Control
Cruise Control
Minimum Speed
The minimum speed at which Cruise Control will function. If the vehicle speed falls below this value while cruise control is active, cruise control will disable. If the vehicle speed falls below this value, cruise control can not be set or resumed. Typically, OEM ECUs set this value to approximately 40 km/h (25mph).Maximum Speed
The maximum speed at which Cruise Control will function. If the vehicle speed exceeds this value while cruise control is active, cruise control will disable. If the vehicle speed exceeds this value, cruise control can not be set or resumed.Maximum Wheel Speed Difference
Prevents cruise control from activating or deactivates if individual wheel speeds exceed this preset value. A real world exampleSpeed +/- Increment
How much the target speed will change with each short press of the Accel or Coast buttons
Tuning Settings
Max Control System Error
This value (speed in km/h) signifies the error limit (+/- this value) that is used to calculate the control system error. Where the control system error is the target speed minus the current speed. This is used to reduce any aggressive acceleration when resuming cruise control from a speed far below the target.Max Throttle Ramp Rate
This is the maximum rate at which the throttle will open of close while cruise control is active. This is to ensure ensures acceleration from far below the target is comfortable, deceleration from far above the target is comfortable. Lower values will also be easier on the suspension and transmission components.
