First Claim
Patent Images
1. A control method for selecting cylinder and valve actuation modes in an engine having at least a valve that may be deactivated, the method comprising:
- generating a set of available cylinder and valve modes;
removing cylinder and valve modes from said available set of cylinder and valve modes, based on a group of operating conditions;
determining a cylinder and a valve mode, from remaining active cylinder and valve modes, based on a second group of operating conditions.

14. A control method for selecting cylinder and valve actuation modes in an engine having at least an electromechanical valve, the method comprising:
-
generating a set of available cylinder and valve modes; organizing said set of available cylinder and valve modes based on available engine torque of said engine operating in said available cylinder and valve modes; removing cylinder and valve modes from said set of cylinder and valve modes, based on a group of operating conditions, in order of said available engine torque; determining a cylinder and a valve mode from remaining active cylinder and valve modes of said set of cylinder and valve modes, based on a second group of operating conditions; and operating said engine in said determined cylinder and valve mode. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)

22. A computer readable storage medium having stored data representing instructions executable by a computer to control an internal combustion engine of a vehicle, said storage medium comprising:
-
instructions for generating a set of available cylinder and valve modes; removing cylinder and valve modes from said set of cylinder and valve modes, based on a group of operating conditions; and determining a cylinder and a valve mode, from remaining active cylinder and valve modes, based on a second group of operating conditions.
