Abstract

A method and system for controlling a motor vehicle (1, fig 1A) during an exit from a free rolling phase of operation, comprises adjusting an engine (2) speed to match an input speed of a transmission (3) so as to provide a smooth exit from the free rolling phase of operation to a normal phase of operation. The input speed of the transmission (3) is calculated based upon a composite final drive ratio, the gear ratio of the transmission (3) chosen for the exit and a speed at which the motor vehicle 1 is travelling. A predictive gear sensing system determines a next gear to be engaged and this ratio is used in calculating the input speed of the transmission (3). During the free rolling phase a clutch (10) is disengaged and the transmission (3) is in gear.
