Abstract
?/p>
With the rapid growth in the number of automobile, the quantity and quality of
automobile testing equipment are constantly improved. As an important part of vehicle detection,
vehicle wheel alignment parameter plays an important role in the whole vehicle
?/p>
s safety properties.
If the vehicle wheel alignment parameter is not correct, it will cause some problems, abnormal
wear, driving wandering, wheel shimmy, steering heavy, fuel consumption and so on and affect
the driving safety directly. According to the different measurement methods, it can be divided into
contact and non-contact. Contact measured by cable-typical, as non-contact, optical measure is
typical, such as laser measure.
