The Design of 1/10 Scale Model for Autonomous Electric Vehicle Dynamic Testing

Abstract

In designing an autonomous electric vehicle control system, a model representing the actual system could provide convenience to the research object because the design can focus only on the area that needs to be researched. However, it is necessary to know the dynamic characteristics of the scaled model, which is used as a reference in designing motion control in autonomous vehicles, especially when braking. Most researchers use low-cost mathematical modelling to test the dynamic reaction of the vehicle during braking. However, it might not fully show real-world responses, so using scaled models is expected to bridge the problem. Testing was carried out on a vehicle model with a scale of 1:10, which focused on stability during its braking. As a result, braking comfort is obtained with a deceleration value below 2.94 m/s2, a stopping time of more than 1.3 s and a stopping distance not exceeding from 200 cm. These results can be adopted as a guideline for the motion control design in the autonomous electric vehicles model.
