Patent DE-19731728-A1 (DE)
Title: Drive power control arrangement for motor vehicle
Inventor: TAKADA MITSURU
IPC: F02D9/02
Filed: 1997-07-23
Abstract: The arrangement includes an automatic transmission gearing and a throttle system with an aperture which is independently controllable. A detection arrangement detects a special step-down instruction, which is output to the automatic transmission gearing, when an accelerator pedal is not pressed. A throttle valve control arrangement opens the throttle valve, so that an engine performance is increased before the automatic transmission gearing is actually switched down in response to a detected special step-down instruction. An ignition control arrangement delays a moment of ignition from a point in time, at which the engine performance is increased, to a point in time, which lies directly before the actual execution of switching down of the automatic transmission gearing. The delay equalizes the increased engine performance which is caused through opening the throttle valve. The ignition control arrangement removes the delay of the moment of ignition, after the stepping down of the automatic transmission gearing is actually executed.
