A shifting system used in combination with a motor-vehicle engine having an output connected via a clutch to the input of a multiratio transmission in turn having an output connected to a load comprises respective sensors for detecting the speeds of the motor output, transmission input, and transmission output and for generating outputs corresponding thereto, and respective clutch and transmission sensors for detecting the settings of the clutch and transmission and generating outputs corresponding thereto. A shifter element can move between an actuated position and an unactuated position. A double-display has a current-setting part and an ideal-setting part and is connected to a controller that is also connected to the sensors. This controller displays on the current-setting part the current setting of the transmission and on the ideal-setting part a setting calculated to be ideal based at least on engine characteristics and transmission output speed. In addition it resets the transmission by means of its actuator to the ideal setting when same is different from the current setting, the selector element is in the drive position, and the shifter element is actuated. It also disengages and engages the clutch by means of its actuator on any transmission speed change and engaging the clutch by means of its actuator on startup of the motor vehicle from halt. |
