Control method and system for vehicle starting

摘要

A method for controlling a vehicle having a first clutch (5) mounted between an engine (1) and a gear drive transmission, and dog clutch type torque transmission means (18, 19) disposed between an input shaft (11) and an output shaft (12) of the gear drive transmission, and wherein the first clutch (5) is controlled at starting the vehicle or at gear shifting, comprising the steps of controlling a transmission torque of the first clutch (5) based on a difference between the engine speed/revolution speed of the input shaft (11) at starting the vehicle so as to control a quantity of increase in a transmission torque of the first clutch (5) in accordance with the value of the difference; and controlling the engine torque based on the transmission torque of the first clutch (5) so as to increase the engine torque according to an increase in the transmission torque of the first clutch (5).
