Control method and control system for continuously variable valve lift mechanism and vehicle

A vehicle, provided with a control system for a continuously variable valve lift mechanism comprising:

• a driver configured to drive and force the continuously variable valve lift mechanism to move to a maximum lift position, and trigger a self locking function to self lock the continuously variable valve lift mechanism at the maximum lift position when the continuously variable valve lift mechanism reaches the maximum lift position, wherein the continuously variable valve lift mechanism is configured such that at the maximum lift position, a resultant force of a roller assembly thereof on an eccentric wheel has a direction passing through an axis of an eccentric shaft, so as to self lock the continuously variable valve lift mechanism at the maximum lift position when the continuously variable valve lift mechanism reaches the maximum lift position in a limp mode.
