Abstract
Abstract : This paper discusses about analyzing in-wheel vehicle’s dynamic motion and load torque. Since in-wheel vehicle controls each left and right driving wheels, it is dangerous if vehicle’s wheels are not in a cooperative control. First, this study builds the main wheel control logic using PID control theory and evaluates the stability. Using Carsim-Matlab/Simulink, vehicle dynamic motion is simulated in virtual 3D driving road. Through this, in-wheel vehicle’s driving performance can be analyzed. The target vehicle is a rear-wheel drive in D-class sedan. Second, by using the first In-wheel vehicle’s performance results, it derivate the drive motor’s dynamic load torque for applying the dynamometer. Extracted load torque impute to dynamometer’s load motor, linear experiment in dynamometer can replicated the 3-D road driving status. Also it, will be able to evaluate the more accurate performance analysis and stability, as a previous step of actual vehicle experiment. Key words : Inwheel(인휠), Carsim(카심), Driving performance(주행 성능), Load torque(부하 토크), Dynamo-meter(동력 시험계)
