Elastic control method for automatic transmission case choke

Abstract

The invention discloses a method for controlling the elasticity of a throttle of an automatic gearbox. The method is implemented by the following steps of: collecting signals from an accelerator pedal sensor and signals from a throttle position sensor, automatically adding or subtracting signals in a timed interruption according to the opening degree of an accelerator pedal, converting the self-added or self-subtracted signals in the timed interruption into a target position of the throttle to control a motor of the throttle. Accordingly, under the conditions of sudden acceleration or deceleration of the accelerator pedal, the invention can avoid the over-high instantaneous accelerated or decelerated speed, enable the smooth acceleration or deceleration along with the operation of the accelerator pedal, and ensure the riding comfort and fuel efficiency. The inventive throttle control method has good stability, accuracy and real-time property and can meet the operating requirement of AMT.

Description

【Technical field】

[0001] The invention relates to a control method, in particular to a control method for a throttle valve of an automatic gearbox of an automobile. 【Background technique】

[0002] The throttle system of the engine is an important part of the control system of the electromechanical automatic transmission (AMT), through which the engine speed is controlled. During the non-shift period, the role of the throttle is to control the flow of the fuel-air mixture entering the engine, which is linked with the opening of the accelerator pedal. The accelerator system can change the speed of the vehicle in real time with the accelerator pedal, thereby satisfying the driver's power and requirements for the vehicle. Vehicle speed requirements; during gear shifting, the engine speed is properly adjusted to facilitate new gear matching, which can not only reduce the speed difference between the master and driven discs of the clutch, speed up the clutch engagement, shorten th...
