What is?
appeared to slide the front wheel outside of the curve, commonly known as “pushing head.”
2
expression
the actual steering angle of the vehicle is smaller than the bending angle of rotation of the front wheel.

Principle
to generate a steering factor deficiencies are many, and adhesion of the tire under certain road conditions generated at a constant value, the centrifugal force and the driving force changes will cause a change in force. When the force is greater than the adhesion, the tire will slide along the direction of the resultant force. If the tire is located in the front, then is the emergence of understeer.
