PURPOSE:To improve the response performance by numerically converting the code of a car-height sensor which reads the value in a prescribed cycle and averaging said values in a prescribed cycle and comparing the average value with an aimed value and judging the start and the stop of car-height adjustment, in a car-height apparatus for the automatic adjustment according to the load, etc. CONSTITUTION:In a CPU44, the outputs of car-height sensors 3a and 3b for detecting the car height in a plurality of car-height ranges are read in the first sampling time over the transition speed of a car-height sensor code which is prescribed by the resonance frequency under a chassis spring, and calculation is performed with a car speed 29, etc., and an aimed car height can be obtained. The car-height sensor codes are added through the numerical conversion according to the aimed value of the car-height and averaged in each cycle longer than the resonance frequency over the chassis spring and memorized and renewed in succession. Start and stop of height adjustment are judged by comparing the average value with the value corresponding to the aimed value. Thus, the response performance in car-height adjustment can be improved. |
