PURPOSE:To give a driver such a speed change timing instruction as to optimize the fuel consumption rate by comparing the outputs of a throttle sensor and an engine revolution rate sensor with target values and selectively generating an up- shift or down-shift instruction for a speed change gear. CONSTITUTION:A memory unit 1 sores a throttle opening targer value thetatar, that is, an optimum throttle opening corresponding to the engine revolution rate. The memory unit 1 is fed with a real engine revolution rate signal from an engine revolution rate sensor 2 as information appointing an address, and feeds the information at the appointed address, that is, the throttle opening target value thetatar to a comparator. The comparator 3 compares the target value thetatar fed from the memory unit 1 with a throttle signal thetareal fed from a throttle sensor 4, and feeds an up-shift or down-shift instruction to a speed change instructor 5. |
