Abstract

PURPOSE:To prevent shift shuck during drive by prohibiting the shifting operation until a subsequent increase of the amount of stamping is obtained, in case the stamping amount of accelerator pedal is reducing at a rate exceeding the specified deceleration. CONSTITUTION:In this automatic speed changer, a micro-computer 1, into which output signals from a car speed sensor 2 and a throttle sensor 3 are fed, decides which shift position shall be set according to the speed-change pattern determined previously, and this is used to make On/Off control of solenoids 4, 5 for changing the speed. At this time, the micro-computer 1 makes operation about the rate of change in the opening of throttle, i.e. the changing speed, on the basis of output signal from the throttle sensor 3. When deceleration of the opening of throttle exceeds a certain specified value, the shifting operation with the speed change gear is prohibited until the subsequent increase of the opening of throttle is obtained. Thereby shift shock given by quick release of accelerator pedal can be prevented.

Description

【発明の詳細な説明】 本発明は自動車等の車輌に用いられる自動変速機の制御
方法に係る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of controlling an automatic transmission used in a vehicle such as an automobile.

変速段を自動的に切換えるようになっている。Automatic transmissions for vehicles generally include a gear transmission mechanism that changes between multiple gears, and the cough-skewer transmission mechanism changes the vehicle's output depending on the vehicle speed and the amount of accelerator pedal depression (throttle opening). The gear speed of the gear transmission mechanism is automatically changed according to a predetermined speed change pattern in a manner that achieves a balance between performance and fuel efficiency.

グを悪化する。In the shift pattern set in the manner described above, the shift point of the gear transmission mechanism shifts toward higher vehicles as the amount of depression of the accelerator pedal increases. Therefore, even if the vehicle speed is constant, an upshift may occur when the amount of accelerator pedal depression decreases, and this upshift does not cause a large shift shock when the accelerator pedal is gradually released. When the accelerator pedal is suddenly released and the speed at which the accelerator pedal depression is reduced is fast, the engine's output torque suddenly decreases, resulting in a large shift shock and a rattling noise in the vehicle drive system. This causes abnormal noise and worsens the driving feeling of the vehicle.

が改善されるようになる。Assume that the manual shift range of the automatic transmission is set to the D range, the throttle opening is O, and the vehicle speed is O, that is, the vehicle is being driven at idle. The gear position of the gear transmission mechanism at this time is the first speed. From this state, the accelerator pedal is depressed and the throttle speed increases, the state shifts to the state shown by ad in FIG. Then, the pressure on the straw accelerator pedal is suddenly released, and the throttle opening becomes O.
When the throttle opening reaches the 0 point, the gear transmission mechanism attempts to shift up from 1st gear to 2nd gear by crossing the 1→2 shift up line during the throttle opening reduction process, but at this time, the gear transmission mechanism attempts to shift up from 1st gear to 2nd gear. When the reduction speed is equal to or greater than a predetermined value, the -heavy speed mechanism is held at the first speed, and that gear position is held until the next throttle opening is increased. In this way, when the throttle opening is reduced above a predetermined reduction speed, shifting of gears in the gear transmission mechanism is prohibited, thereby avoiding large shift shocks and abnormal noises, and improving the drive feel of the vehicle. Rings will now be improved.
