Abstract
As to agricultural vehicles, it is necessary to prevent tires from slipping when running on a ridge road. If electric motors are used to drive the wheels of an agricultural vehicle, it is easy to control the driving force of each wheel.
In this study, a traction control system with an original peak search method of the driving force was applied to an agricultural electric vehicle for improving vehicle stability. A simulation model for the power train of one of the driving wheels of an agricultural electric vehicle with the traction control system was composed and identified with a fixed experimental apparatus.
By numerical simulations, it has been confirmed that the slip ratio between a tire and a road can be kept at optimum states under very slippery conditions.
