Title: Method of controlling speed change of automatic speed change gear
Inventor: URIYUUHARA MAKOTO
IPC: B60W10/10
Filed: 1984-05-26
Abstract: PURPOSE:To eliminate unnecessary gear shifts between gear shift stages in an automatic speed change gear, by selecting an optimum gear shift position from a shift map after variation of acceleration due to depression of accelerator is stabilized. CONSTITUTION:When the degree of depression of an accelerator pedal 15 is decreased, a depressing amount AP is delivered. An AC counter 14f compares the previous depressing amount AP with the present depressing amount AP to determine whether the variation of the depressing amount becomes zero or not, that is whether the variation of acceleration or deceleration has been stabilized or not, and starts to count the elapse of time from the time point at which the variation becomes zero. Until a set time elapses, the gear shift stage of a speed change gear 6 is held at the previous gear shift stage. When the set time has elapsed, an electronic control device 14 reads out an optimum gear shift stage OPT in accordance with the depressing amount and a vehicle speed V. The OPT is compared with the present gear shift stage GP. If they are not coincident with each other, the gear shift stage of the speed change gear 6 is set at a new optimum OPT.
