Cruise Control Shift Strategy

Cruise Control Shift Strategy

The cruise control function supports speed controlled operation to achieve smooth overall driving characteristics. This function ensures that the acceleration requested of cruise control is achieved while ensuring comfort is not impaired by increased gearshifts.

When cruise control is activated by the ECM, the transmission control module is notified over the PT-CAN bus. The transmission control module activates the program for cruise control operation which minimizes locking/unlocking Of the torque converter clutch and up/down shifting. Additionally, the cruise control can request a downshift if the vehicle speed exceeds the set speed limit when coasting downhill.
