ABSTRACT:
In order to control shifting of the transmission of a vehicle, from the viewpoint of obtaining the optimum fuel economy and/or power output performance, a transmission shift control device is proposed which comprises a throttle sensor which generates a throttle signal, an engine speed sensor which generates an engine speed signal, a shift position sensor which generates a shift position signal indicating the present operating gear of the transmission, a memory which stores a relationship between the throttle opening and the engine speed for each shift position or operating gear of the transmission to give a target value for one of these two signals in accordance with the other of them, and a comparator which receives one of the above two signals and compares it with the target value therefor given from the memory and generates either an upshift signal or a downshift signal which is indicated to the driver or sent to the transmission so as automatically to shift it.
