This chapter integrates tire performance data, steering, suspension kinematics/compliance and weight transfer into a unified visualization of vehicle steady state performance. It discusses the tire force and moment convention that is generally used to define the tire contact patch forces and offers an alternative convention that clarifies the visualization of the forces acting upon the tire contact patch for suspension kinematic and compliance design. Wheel end architecture is examined considering different supporting link arrangements and a case is presented to consider rear wheel end caster angle as a significant contributor to vehicle dynamic performance. Vehicle kinematic and compliance design principles and engineering practices are presented for a integrated kinematic and compliance design solution. The consequences of roll center location and migration and inherent compliance characteristics due to kinematic design are discussed. Measured kinematic and compliance test data is presented and discussed. Vehicle weight transfer and weight transfer distribution due to mass properties, wheel rates and roll center locations is presented and overlaid upon tire lateral force vs. slip angle data to reveal tire (axle) pair and vehicle performance considering the grip utilized at each tire contact patch. The overlay of vehicle weight transfer onto tire data offers a fundamental methodology to examine the state and utilization of each tire during a cornering maneuver. Further it provides a basis of logical methodology to optimize corner loads and individual steering angles for fuel consumption efficiency or for maximization of cornering performance.
