The invention discloses a whole vehicle starting and gear shifting control method for a TCC and AMT transmission clutch, and belongs to the technical field of automobile design and manufacturing. The vehicle weight and the vehicle working mode after a vehicle is started and runs are obtained; judging whether the whole vehicle is no-load or full-load according to the vehicle weight, and outputting an instruction in combination with a vehicle working mode; and the hydraulic torque converter and the clutch are adjusted according to the instruction, and whole vehicle starting and gear shifting are achieved. Through parameters such as the vehicle weight, the driving mode and the driving intention of a driver, the vehicle control can give full play to the driving advantages of strong torque transmission of the hydraulic torque converter and stable torque transmission of the clutch. The controller independently controls the hydraulic torque converter and the clutch in the economic mode and the power mode, and therefore the requirements of a driver for the power performance and the economical efficiency can be better met.
本发明公开了一种TCC和AMT变速器离合器的整车起步和换挡控制方法,属于汽车设计制造技术领域,获取车辆启动行驶后的车重及车辆工作模式;根据车重判断整车空载或满载,并结合车辆工作模式输出指令;根据指令调节液力变矩器及离合器,实现整车起步和换挡。通过车重、驾驶模式以及驾驶员驾驶意图等参数,车辆控制能够充分发挥液力变矩器传扭强劲以及离合器传扭平稳的驾驶优势。控制器在经济模式和动力模式下通过对液力变矩器和离合器的单独控制,从而能更好的满足驾驶员对动力性和经济性的需求。
