The car frame deviation eight overall deformation.
Both sides of the wheelbase difference, exceeds the maximum allowable range can be measured with a tape measure. If it is beyond the scope of must use calibration rig is corrected.
The car frame deviation eight overall deformation
Check whether the vehicle tracking method
In general, the car on a flat straight road on the road 1000 meters, the maximum deviation should be controlled within four or five meters is normal. Beyond this index, it means that the car appeared the phenomenon of deviation.
Check whether the vehicle running steps:
Find a remote, the formation of pavement, first on the right-hand side of the road, uniform and adjustable positive after the vehicle's driving direction let go, to 200 meters observation vehicle for the benchmark (usually four road lamp pole distance direction of travel. This time you will be found to have slightly to the right side, turn around, on the left side driving, we must pay attention to safety oh) is running in lane just now, or uniform, is the direction of travel of the vehicle let go or to 200 meters observation vehicle for the benchmark (usually four road lamp pole distance direction of travel (the best is you just drive 200 meters). This time you will find that the vehicle is slightly to the left. (in view of the characteristics of roads is on the left side of the tire surface will be slightly higher than that on the right side of the tire pavement, so in the road straight if the feel of the vehicle is slightly skewed to the right, don't worry, is a normal phenomenon.)
