ABSTRACT:
An electronically controlled transmission arrangement for an internal combustion engine driven vehicle such as a private automobile, permitting operation under normal conditions close to regions of minimum specific fuel consumption while also permitting bringing an engine in poor operating condition close to its maximum power speed. A transmission including a continuously variable gearing is controlled by an electronic microprocessor in response to signals representing driver-selected power-command, engine-speed, and drive shaft speed. The transmission is controlled so that the engine vehicle combination operates along an engine power-load line selected according to the power command. Transition circuitry prevents a sudden change in power-command from causing the transmission to alter its ratio so quickly that there is a transient change of delivered torque in the wrong direction.
