13 Online Measurement and Calibration

Vehicle Control Unit VCU configuration

– System configuration (c display configuration, CAN I/O, etc.) is stored in the

Vehicle Control Unit VCU

– Use RaceCon to create and download configuration from the PC to Vehicle Control

Unit VCU Communication interface: Ethernet

– Communication protocol: XCP

Online Measurement and Calibration

– System status and diagnosis

– Check and calibrate sensors in the vehicle

– Live display of sensor values on the PC

– Use RaceCon for diagnosis, online measurement and calibration

– Communication interface: Ethernet

– Communication protocol: XCP

13.1 Setting up an online measurement

Vehicle Control Unit VCU supports online measurement of sensor values and diagnostic

variables.

Expand ‘Measurement Container’ and ‘Measurement Folder 1’ in the Project Tree and

double-click on ‘Sheet1’. Alternatively, click on the ‘Calibration/Measuring’ tab to

open the window directly.

‘Sheet 1’ opens in a new ‘Calibration/Measuring’ window.

RaceCon changes
automatically
to "Calibration/
Measuring"
