GEARSHIFT SELECTION SYSTEM FOR A POWER-ASSISTED TRANSMISSION

A vehicle gearshift mechanism for a power-assisted transmission with a unilateral gearshift actuator which can be moved into speed selection positions and into a neutral position. The gearshift only has one speed selection position for a shift-up or shift-down, respectively. A respective optimum gear is assigned to the speed selection positions by an electronic evaluation control circuit. The evaluation control circuit receives signals representing the speed and the respective driving conditions of the vehicle to shift to the optimum gear.
