Abstract

The present invention provides a method and system for controlling self-learning of a continuously variable valve lift system. Whether the variable valve lift system needs self-learning; if the continuously variable valve lift system needs self-learning, then judge whether the continuously variable valve lift system can perform self-learning, if the continuously variable valve lift system does not need self-learning, Then the continuously variable valve lift system enters the normal lift control mode. If it is judged that the continuously variable valve lift system can perform self-learning, then control the continuously variable valve lift system to perform self-learning. If the system cannot perform self-learning, the continuously variable valve lift system is controlled to enter the failure lift control mode. The method and system in the invention can effectively improve the problem of low lift control accuracy of the continuously variable valve lift system.

Description

technical field [0001] The present invention relates to the technical field of vehicles, in particular to a method and system for controlling self-learning of a continuously variable valve lift system. Background technique [0002] With the continuous consumption of energy and the improvement of automobile emission requirements, the engine power, economy and emission of vehicles have become the focus of attention. Because the vehicle can use the CVVL (Continuously variable valve lift, continuously variable valve lift) device to change the valve lift according to the different working conditions of the engine, reduce the pumping loss and friction loss, thereby reducing the fuel consumption and improving the power of the engine. Therefore, continuous The application of variable valve lift systems in vehicles has become a new trend. [0003] In the process of adjusting the valve lift of the engine through the continuously variable valve lift system to control the intake air vo...
