Method for testing for error in measuring load in an internal combustion engine with variable valve lift control

摘要

The plausibility check takes place in such a way that a first piece of load information is derived as a function of the throttle valve position and a differential pressure determined from the pressure upstream of the throttle valve and the pressure downstream of the throttle valve. In addition, a second piece of load information is derived as a function of the intake valve lift and the engine speed. The smaller of the two pieces of load information is compared with the measured load. If this measured load deviates from the load information an error of the measured load is signaled.
