An introduction to understeer. What is understeering ? How does a car understeer ?
Depending on the road conditions, speed, and the traction available, a car may understeer or oversteer. However, the design of the car will tend to produce a specific “terminal” condition, as the car is forced to and past its limit of adhesion. As the result of the design of a car, it tends to understeer [...]
Terminal handling conditions can be termed as a function of the length of the car and front/rear weight distribution (and thus the polar moment of inertia of the car) and the front/rear tire traction. The front/rear tire traction is further modified by the relative toll stiffness of the front and rear, that affect the outward [...]
The lateral velocity of a wheeled vehicle with pneumatic tires, while cornering under high speed will be greater than the speed in the direction to which the wheels are pointed. Here high speed indicated anything greater than approximately 10 mph or 16 kmph. The angle between the direction of a pointing of a rolling wheel [...]
The handling condition during cornering in which the circular path of the car’s motion is of a greater diameter than the circle indicated by the direction the car’s wheels are pointed is termed as Understeer. In other words, understeering happens when the front of the car does not have as much grip as the driver [...]
