Abstract:
A method for controlling an automotive vehicle having a first clutch mounted between an engine and a gear drive transmission, for connecting or disconnecting torque transmitted from said engine to driving wheels, and a torque transmission disposed between an input shaft and an output shaft of said gear drive transmission, wherein said torque transmission is of the dog clutch type, and wherein said first clutch is controlled at starting the vehicle or at gear shifting, thereby to continuously increase a transmission torque of said first clutch to said input shaft of said gear drive transmission, said method comprising the steps of:upon starting the vehicle, controlling the transmission torque of said first clutch to increase a quantity of increase in a transmission torque of said first clutch in proportion to a difference between an engine speed and an input shaft revolution speed; and controlling a torque of said engine based on the transmission torque of said first clutch so as to increase the torque of said engine according to an increase in the transmission torque of said first clutch.
