Abstract
An arrangement for adjusting a transmission, such that the gear ratio is continuously adjustable and the transmission is mounted between a vehicle engine and the vehicle wheels. An actuator which influences engine power is acted upon via an accelerator pedal controlled by the driver. In addition to the accelerator pedal position, the vehicle speed and/or the engine rpm are applied to adjust the transmission gear ratio. The adjustment of the transmission gear ratio is made in such a manner that a substantially linear relationship is obtained between the position of the accelerator pedal and the tractive force acting on the drive wheels. The advantage is that a linear characteristic is obtained between the accelerator pedal position and the tractive force (that is, the transmission output torque). The linear characteristic is obtained by a targeted configuration of characteristic fields stored in a microprocessor memory.
