Abstract
An optimum shift timing indicating device for a vehicle includes: a speed sensor for detecting a rotational speed of an engine or a running speed of the vehicle; a load sensor for detecting an engine load; a data processing device having a data map or maps fewer in number than gear positions of the vehicle transmission, said data map or maps having a set shift-up region and/or shift-down region selected in accordance with the rotational speed of the engine or the running speed of the vehicle and the engine load, for emitting a shift-up instruction signal and/or a shift-down instruction signal in accordance with the rotational speed of the engine or the running speed of the vehicle and the engine load; and a shift instructing device for giving a driver a shift-up instruction and/or a shift-down instruction in response to an output from said data processing device; so that instruction about the optimum shift timing can be given to the driver with the use of only a small memory capacity.
