Title: METHOD FOR OPERATING AN INTERNAL COMBUSTION ENGINE OF A HYBRID MOTOR VEHICLE DURING A STARTING PROCESS OF SAID INTERNAL COMBUSTION ENGINE
Abstract:
The present invention relates to a method for operating an internal combustion engine (20) of a motor vehicle during a starting process of the internal combustion engine (20). The method comprises: obtaining a lubrication state variable which represents a lubrication state of the internal combustion engine (20); determining (61) a maximum permissible torque (Mv,z) of the internal combustion engine (20) depending on the lubrication state variable; and operating (62) the internal combustion engine (20) at an operating torque which is equal to or less than the determined maximum permissible torque (Mv,z). The invention also relates to an engine controller for carrying out the method.
