Abstract

A method for controlling the initial start of vehicle features that the rotation speed of engine and the position of throttle pedal are detected for controlling the position of clutch. Its controller is composed of a signal acquisition unit with throttle pedal position sensor and rotation speed sensor of engine, an electric control unit consisting of data receiving module, data processing module and data control module, throttle motor, and clutch motor.

Description

technical field [0001] The present invention relates to a control device and method for a vehicle, more particularly to a control device and method for starting a vehicle. Background technique [0002] In the control system of the electro-mechanical automatic transmission (AMT), in order to complete the starting of the vehicle, the engine, the clutch and the transmission must be controlled comprehensively. Vehicle starting refers to the process of increasing the vehicle speed from stationary to the minimum stable speed. To achieve a stable increase in vehicle speed, the engine must be controlled to cooperate with the clutch when shifting gears. However, the existing control devices and methods do not apply the impact force as a limit to the control system during the control process, which reduces the comfort of passengers. Therefore, further improving the smoothness when starting and shifting gears will become a key issue of the starting control device and method in the veh...
