Automotive Suspension Design - Vehicle Level Targets

Vehicle Level Targets

A partial list would include:

  • Maximum steady state lateral acceleration (in understeer mode)
  • Roll stiffness (degrees per g of lateral acceleration)
  • Ride frequencies
  • Lateral load transfer percentage distribution front to rear
  • Roll moment distribution front to rear
  • Ride heights at various states of load
  • Understeer gradient
  • Turning circle
  • Ackermann
  • Jounce travel
  • Rebound travel

Once the overall vehicle targets have been identified they can be used to set targets for the two suspensions. For instance, the overall understeer target can be broken down into contributions from each end using a Bundorf analysis.
