摘要
An electronic control system for controlling an automatic transmission mounted on a vehicle determines whether a vehicle speed sensor is abnormal or not when the transmission gears are in a neutral gear position. If the vehicle speed sensor is abnormal, then vehicle speed data immediately before the vehicle speed sensor becomes abnormal is stored, and a gear position is determined based on the stored vehicle speed data for a predetermined period of time after the transmission gears are shifted from the neutral gear position to another gear position.
