Abstract:
1. A method of changing gear in an automated transmission system of a motor vehicle including: a multi-ratio gearbox having at least two shafts including an input shaft and an output shaft; a take-up clutch located between the input shaft and an output shaft of an engine by which torque may be transmitted between the engine and the input shaft; a number of pairs of intermeshing gears, one gear of each pair being mounted in fixed rotational relationship with one of said shafts and the other gear of each pair being rotatably mounted with respect to another shaft; the rotatably mounted gears of each pair of gears having means for selectively rotatably securing the gears to said other shaft; a power shifting clutch being adapted to rotatably secure the rotatably mounted gear of a first pair of gears to said other shaft; and means for sensing the speed of the input shaft and the speed of the output shaft of the gearbox; in which when the vehicle is in motion, the take-up clutch will be engaged to transmit torque from the engine to the input shaft of the gearbox and the rotatably mounted gear of one pair of gears is rotatably secured to said other shaft to engage said pair of gears and transmit torque from the input shaft to the output shaft; said method comprising:
