Title: Controlling method of fuel feeding amount for internal combustion engine
Inventor: DEMEL HERBERT
IPC: F02D41/12
Filed: 2000-06-27
Abstract: PROBLEM TO BE SOLVED: To generate no dangerous traveling state in an engine brake driving state. SOLUTION: An engine brake driving is recognized by a position of an acceleration pedal and a revolution number detected of an internal combustion engine and a fuel feeding amount at the time of engine brake driving is determined according to a present traveling state of vehicle. When a curve traveling is recognized, a fuel cut at the time of engine brake driving is carried out if the vehicle is in the undangerous traveling state and the fuel cut at the time of engine brake driving is carried out if the vehicle is in the dangerous traveling state. By such a constitution, it can be prevented that the dangerous traveling state is generated in the engine brake driving state at the time of curve traveling.
