PURPOSE:To permit proper switching of speed-change pattern by obtaining corrected standard acceleration obtined by adding acceleration for hysteresis to the standard acceleration, as comparison subject, when several kinds of speed change patterns are selected on the basis of the result of comparison of the acceleration actually measured with the standard acceleration. CONSTITUTION:The actually measured acceleration alpham is obtained from the output of a car speed sensor 1 through a differentiator 3, and the standard acceleration signal corresponding to the slope of road is obtained through a standard acceleration arithmetic circuit 7 from the outputs of the car speed sensor 1 and a throttle sensor 2. The output of the sensor 2 is input into hysteresis decision circuits 10-1-10-3. Each circuit 10-1-10-3 is for D pattern (Normal travelling), S1 pattern (5% road slope), S2 pattern (10% road slope), and selectively operated by the signal of a speed change pattern decision logic circuit 11. The output of each decision circuit is input into adders 8 and 9 resepectively with the output of the arithmetic circuit 7, and the outputs of the adders are input into comparators 4 and 5 respectively. |
