Abstract
A neutral idle hill detection system for a vehicle with an automatic transmission comprises a range selection input device that receives an operating range of a transmission. A throttle position input device receives a throttle position signal. A transmission output speed input device receives a transmission output speed signal. A transmission temperature input device receives a temperature signal. A brake status input device receives a brake signal. A control module receives the range, the throttle position signal, the transmission output speed signal, the temperature signal, and the brake signal, detects a hill condition based on the received signals, and controls a first clutch of the transmission based on the hill condition.
