A control device and method for starting an AMT vehicle are provided, the device includes a signal acquisition unit, an electronic control unit, a throttle motor and a clutch motor, the electronic control unit includes a data receiving module, a data processing module and a data control module, the The data receiving module is electrically connected to the signal acquisition unit, and the data control module is electrically connected to the accelerator motor and the clutch motor. It is characterized in that the signal acquisition unit includes an accelerator pedal position sensor and an engine speed sensor. Using the control device and method for AMT vehicle starting provided by the present invention, the position of the clutch can be controlled by detecting the engine speed and the position of the accelerator pedal, so as to achieve the cooperation between the engine and the clutch. Therefore, the vehicle can start smoothly, thereby reducing the impact and improving the comfort of the driver and passengers.
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...
