ABSTRACT:
An electronic control system for controlling an automatic transmission determines a gear position based on vehicle speed data immediately before a power supply is cut off. The gear position is determined during a transient period occurring after the electronic control system is reset by the power supply cutoff, until the control system resumes stable operation. Even when the electronic control system is reset by the instantaneous power supply cutoff while the vehicle is travelling, the electronic control system allows the vehicle to run safely without erroneous gear shifting immediately afterwards.
