Optimum shift timing indicating device for a vehicle

An optimum shift-timing-indicating-device for a vehicle comprising:

• a vehicle speed sensor for detecting a running speed of the vehicle;
• a load sensor for detecting an engine load;
• a data processing means having at least one data map so that a number of data maps is fewer in number than a number of gear positions of a transmission of said vehicle, said data map having a set shift-up region and a set shift-down region varying in accordance with the running speed of the vehicle and the engine load, for emitting one of a shift-up instruction signal and a shift-down instruction signal in accordance with the detected running speed of the vehicle and the detected engine load;
• and
• shift instructing means for giving a driver one of a shift-up instruction and a shift-down instruction in response to the instruction signals output from said data processing means.
