Abstract:
Method for adjusting the driving performance of a motor vehicle having an internal combustion engine with spark ignition, comprising:determining a set torque value M.sub.set based on a desired torque input by driver of the vehicle, and possibly additional desired torque requirements; andadjusting engine torque to achieve the set torque value M.sub.set by influencing at least one of a load and an ignition angle of the engine; wherein,adjustment of engine torque is performed based on an operating state of said vehicle, determined from vehicle operating conditions;in a first operating state torque adjustment is performed in an efficiency-optimal fashion by load regulation;in a second operating state the torque adjustment is accomplished as rapidly as possible by an additional ignition angle adjustment; andin a third operating state torque specification for load regulation is established and residual torque adjustment is accomplished by an additional ignition angle adjustment.
