The Effects of the Tire Camber Angle on Vehicle Controllability and Stability 860245

ABSTRACT

Lateral force and aligning torque are measured to clarify quantitatively the changes in cornering characteristics due to the tire camber angle. In the measurements, the slip angle, normal force and tractive force are given as the parameters. The results show that the aligning torque decreases while the lateral force increases and that both changes are proportional to the angle of negative camber. Further, it is found that the rate of change depend on the normal force, slip angle and tractive force.

The effects of the camber angle on controllability and stability are simulated using tire bench-test data. It is found that initial negative camber improves steering response and turning performance. This result agrees well with the findings of actual vehicle driving tests.
