Shift and throttle management during cruise control

摘要

A control system for regulating operation of a vehicle having a transmission driven by an engine during a cruise control mode includes a first module that determines an operating point of the vehicle and that compares the operating point to one of a shift line and a torque converter clutch (TCC) release line. A second module regulates a throttle of the engine to maintain the operating point a threshold distance from the one of the shift line and the TCC release line, when the operating point is at the threshold distance.
