This model is a simulation model designed for evaluating turning performance and ride comfort of BEVs (Battery Electric Vehicles). It is utilized in our educational service, digital development exercises.
The oval course is equipped with bumps, allowing for the measurement of roll angle and vertical acceleration to evaluate ride comfort.The overall vehicle configuration consists of road environment, driver, control, and vehicle physical models. The control system is composed of vehicle dynamics and driving control, as well as various unit controls. The vehicle physical model includes the battery, motor, inverter, vehicle (a 3-axis, 6-degree-of-freedom vehicle model), and steering.
List of signals:
- Driver Signals
Accel operation, Brake operation, Steering Angle

* In this model, the x, y and z-axis direction is defined Vehicle Cartesian coordinate system. (The positive direction of the x-axis is to the front of the vehicle, the positive direction of the y-axis is to the left of the vehicle, and the positive direction of the z-axis is to the top of the vehicle.) For roll, pitch, and yaw are defined in right-handed coordinates.
