Shifting timing indicating system for a vehicle |
摘要 |
A shifting timing indicating system for a vehicle includes a control circuit having an engine rpm sensor for detecting the engine rpm and a rpm comparator which receives the output of the engine rpm sensor and determines whether the engine rpm exceeds a preset value. The control circuit outputs a shift-up signal when the engine rpm exceeds the preset value. A shift-up indicator receives the shift-up signal from the control circuit and makes a shift-up display to direct the operator of the vehicle to shift up. An acceleration detecting circuit detects the rate of increase in engine load and the shift-up indicator is inhibited from making the shift-up display for a predetermined time interval which is extended with increase in the rate of increase in engine load. |
