Abstract:
A control method of an internal combustion engine in a motor vehicle, comprising:a valve mechanism including an intake valve and an exhaust valve combined with a cylinder of said internal combustion engine;a valve mechanism control means for controlling said valve mechanism;an operation status detection means for detecting an operation status of said internal combustion engine;a brake step-on force detection means for detecting step-on force on a brake; andan anti-lock brake system;the method comprising the steps, when said brake step-on force detection means detects said step-on force on said brake and said anti-lock brake system is activated, of closing at least one of said intake valve and said exhaust valve, opening another of said intake valve and said exhaust valve during a suction stroke of the cylinders and controlling a lift of the another of said intake valve and said exhaust valve for restricting a path area of air exiting the cylinder during a compression stroke to control magnitude of compression for engine braking.
