Mechatronics system for tire pressure control

To evaluate the off road vehicle performance, a scaled soil bin was designed and established at Military Technical College (MTC). Using the indoor soil bin, single wheel tester that concludes the dynamic weight equal to that measured statically in addition to measuring sensors, the vehicle performance was measured. Also the dynamic sinkage due to wheel motion was measured using ultrasonic sensor. This paper presents a detailed Mechatronics system for experimental measuring of instantaneous slip ratio, and dynamic sinkage on soft dry sand. The data acquisition card and LABVIEW program are considered the Mechatronics pressure control system. Also this paper introduces a development and implementation of a control algorithm for tire pressure control. The control system depends on the signal from tire pressure sensor, the signal from speed sensors and signal from dynamic sinkage to control the tire pressure via directional control valve (inflation/deflation) automatically based on road conditions.
