Mileage Accumulation Chassis Dyno Laboratory
The type of tests that can be performed in the Mileage Accumulation facilities are as follows:
- Standard endurance testing according EC, EPA, Indian, Japanese or other regulations
- Specific Drive Cycles, e.g. customer defined accelerated endurance cycle, vehicle running in cycles, journey simulation, etc.
- Customer defined (R&D) tests (e.g. in vehicle gearbox testing, simulated vehicle operational tests) & Performance Tests
- The systems are equipped with Robot driving (Auto Pilot).
Auto Pilot
