“HUMAN DRIVER” DRIVABILITY STYLE

PERFECT REPEATABILITY ON SPECIFIC AND REGULATORY TESTING

STAND-ALONE SYSTEM

Since 2011, GREENMOT Robot driver has been developed for Vehicle Energy Management testing operated in our climatic test cells. These tests require high repeatability for testing correlation. Thanks to its specific algorithm, the robot driver provides high accuracy speed profile, “human driver” drivability style and robustness that is mandatory for all emission and fuel efficiency developments.

GREENMOT Robot driver is able to operate the following kind of test :

  • Emission test
  • Consumption test
  • Vehicle Energy Management test
  • Endurance test
  • Climatic test
  • Transmission & Powertrain test
  • Correlation campaign
  • R&D vehicle test
  • Hybrid & Electric vehicle test

G-ROBOT : High Repeatability during climatic tests

RESULTS & REPEATABILITY

The G-ROBOT driver offers very high driving caracteristics and repeatable results i.e. 0.2% on consumption between comparable WLTC cycles performed at the GREENMOT test center.

REPEATABILITY ON COLD AND HOT WLTC

Moreover the G-Robot is configurable according to several driving styles : eco, standard, sporty in order to fit perfectly with the human driving style. Thanks to its internally-designed algorythm, the inputs of the driving cycle can be adjusted to the several driving configurations needed.

Schema - smooth driving robot
Smooth / eco driving : with anticipation of gear changes.
Schema - sporty driving robot
Sporty-style driving : very dynamic driving without any anticipation (brake pedal vs gas pedal)

These tests can also be performed with thermal fluid regulation.
