Driving Robot Solution

Driving Robot for Chassis Dyno

Summary

The auto throttling robot driver for chassis dynamometer consists of a real time controller, which controls the throttle of a vehicle to maintain the vehicle speed as per driving cycle. Advantage of the system is to run repeatable drive cycles on the chassis dynamometer without human intervention. This is best suitable for running durability tests on chassis dynamometer. Also, this will be helpful in emission development of a vehicle by following drive patterns consistently.

Customer Benefits

  • It has real time controller which controls accelerator and brake and maintains the speed trace of drive cycle (including auto-throttling).
  • Use for automatic vehicle durability tests.
  • Use for emission test bench for conducting tests with good repeatability.
  • The accelerator and brake actuators are easy to mount and the time for vehicle preparation is less than 5 minutes.
  • Gear shift is available optionally.

Accuracy

This solution is also available for passenger cars & commercial vehicles.

Gear Shift Robot

Summary

The gear shift robot for engine transient dynamometer consists of a real time controller, which controls the throttle, clutch and gear with synchronization. The advantage of the system is to simulate the chassis dynamometer drive cycles on the engine dynamometer.

Customer Benefits

  • Using this approach, the chassis dynamometer trials can be conducted in engine dynamometer with transmission.
  • Actuator control for acceleration, gear shifting and clutch. Gear shift sequence is configurable.
  • The validation trials can be started in early stage even before the prototype vehicle is ready. It will shorten product development time.
  • The fuel economy optimization for the drive cycle can be done in engine itself.
  • Emission under different loading conditions can be simulated.
  • Better repeatability due to fully-automated system.

Accuracy

This solution is also available for passenger cars & commercial vehicles.
