(ETC) command 210 is executed, followed by execution of the phaser command 216, a
repeat of the load check 204 and high-load hysteresis check 212. At this point, if the
desired load is equal to or exceeds the predetermined high-load hysteresis threshold,
switching step 214 is executed. Second, in the case where the load check 204 and low-
lift position check 208 determine that the two-step switching device needs to be
switched to the low-lift position, if the low-load hysteresis check 226 determines that the
desired load exceeds the predetermined low-load hysteresis threshold, ETC command
224 and phaser command 222 are sequentially executed. Following execution of
phaser command 222, load check 204 and low-load hysteresis check 226 are repeated.
If in low-load hysteresis check 226 the desired load is less than or equal to the
predetermined low-load hysteresis threshold, two-step switching device 16 is switched
to the low-lift position.
There is no express indication in Kabasin that the phasing is adjusted “so that at
least one condition variable of the combustion of a combustion chamber assigned to
said inlet valve does not change” as called for in each of the claims on appeal and
threshold of the load check 204 to provide hysteresis in the switching of two-step switching device 16 and
thereby provide for a smooth switch thereof and prevent the two-step switching device from oscillating
between the high and low-lift modes.
