13.3 Online calibration of multipoint adjustment
channels
Example: measurement of wheel force
– Physical property ‘wheel force’ not directly measureable
– Load transfer through suspension kinematics
– Physical value at sensor position defined by vehicle
– Curve definition by online adjustment at vehicle
Force at wheel
Force at sensor
1. Create a multipoint adjustment measurement channel. To create a multipoint channel,
see chapter ‘Configuring a multipoint adjustment [}57]’.
2. Download the configuration on the Vehicle Control Unit VCU. To connect the Vehicle
Control Unit VCU to RaceCon, see chapter ‘Setting up a new RaceCon Project’.
3. Click on the desired channel in the Vehicle Control Unit VCU Project Tree.
4. Double-click on a measurement channel in the Data Area to open the online view.
