ABSTRACT:
For generating a transmission shift control command in accordance with the operating conditions of a vehicle engine, from the point of view of improving fuel economy of the engine, a transmission shift control device has a throttle sensor which detects the throttle opening to produce a throttle signal, an engine speed sensor which detects the engine speed to produce an engine speed signal, a throttle comparator which compares the throttle signal with a reference signal, an engine speed comparator which compares the engine speed signal with a reference signal, and a switching circuit which generates an upshift command or a downshift command on the basis of signals from these comparators, these commands being sent to the transmission of the vehicle, or to a display visible to the driver.
