Abstract
A shift indicator system for a vehicle comprises an engine speed sensor for detecting the engine speed, a comparator which receives the output of the engine speed sensor and compares the detected engine speed with a preset speed, an indicator which receives the output of the comparator and provides an indication for directing upshifting, an adverse condition sensor for detecting an adverse condition which can adversely affect the engine output power, and a correcting circuit which receives the output of the adverse condition sensor and increases the preset speed when the adverse condition is detected.
