  • Control system for a motor vehicle drive unit
    Patent number: 4599918
    Abstract: A control system for a motor vehicle drive unit consisting of reciprocating piston engine and of a transmission, in which the drive unit is so controlled that the engine power corresponding to the respective drive pedal position lies always as close as possible but below a stored engine output curve; for that purpose, the engine rotational speed, the drive pedal position, and the engaged transmission speed are determined, whose values are fed to a control apparatus which, in addition to the storage device for the engine power function, also contains stored values for the transmission speeds and which determines and controls the optimum transmission speed in several interrogating and comparison cycles.
