Validation of transmission control software
Daimler uses Silver and TestWeaver to develop and test all members of the 7G-Tronic seven-speed automatic transmissions. This process is used to develop dual clutch transmissions as well. Key features of the development and test process- run transmission control software in closed loop on Windows PC
- control software either generated using Simulink/TargetLink or hand written
- every software release: 24h test run in parallel on several PCs
- thousands of gearshifts generated and analyzed
- code coverage is measured
