Controlling drive shaft torque of car - adjusting fuel quantity in advance during gear shift to match final output torque level

摘要

An electronic control is assigned for drive shaft torque from an engine-gearbox combination in a car. According to the driver's wish, a particular torque level is set and is held constant until the driver chooses otherwise. The torque level is derived from a parameter using the throttle pedal and various engine sensors. The fuel injection quantity is prematurely adjusted to the value it would have at the end of a gear shift process. ADVANTAGE - By premature adjustment of fuel injection quantity, final output torque level is achieved quickly and exactly without overshoot.
