First Claim
Patent Images
1. A method for controlling an intake system in a motor vehicle comprising the steps of:
- determining a current cylinder mode;
receiving information related to a parameter associated with an operating condition of the motor vehicle;
selecting a predetermined range associated with the current cylinder mode, the predetermined range being a range of values associated with the parameter;
comparing the parameter with the predetermined range, the predetermined range having a lower limit and an upper limit; and
using a first intake mode when the parameter is within the predetermined range and using a second intake mode when the parameter is outside the predetermined range.
