As the spread of electric vehicles increases, it is necessary to conduct performance tests that take approximately 6 hours or more to completely discharge the battery, and it is also necessary to conduct tests that take close to 2 hours, such as real driving emissions(RDE) tests, using an indoor chassis dynamometer. In this study, basic research was conducted to develop a driving robot capable of short installation time and automatic calibration to test the performance of a car using a chassis dynamometer. For this, a mechanism is designed and manufactured, which can control the acceleration and brake pedals. In the next stage, it is planned to develop an articulated robot with 6 degrees of freedom based on this and develop a driving robot that can be installed in a short time and perform tests taking long time by following the speed mode prescribed by regulations in the chassis dynamometer.

As the spread of electric vehicles increases, battery performance testing, which takes approximately 6 hours or more until the battery is completely discharged, becomes necessary. The need for automatic testing is increasing due to extremely severe labor stress due to long-term testing and low-temperature testing as well. In this study, a basic research was conducted to develop a driving robot that mimics human pedal movements. Two-degree-of-freedom pedal control mechanism is designed and manufactured that implements a pivoting movement with the heel placed on the floor of the drivers seat, similar to a human. In order to analyze pedal operation movements when driving in the UDDS and HWFET speed modes that constitute electric vehicle testing, cameras were mounted on the vehicle to measure foot movements, and OBD data was used to measure vehicle driving variables. Using these data, the drivers pedal motion movements during electric vehicle testing were analyzed, and will be used to construct a pedal control system in the following study.
