Abstract
We have developed an efficient driving force distribution algorithm capable of minimizing tire slip dissipation power on contact patches during acceleration and deceleration while turning. Although the power dissipation mechanism was also validated from the viewpoint of “macro” input power to wheels, how the power is consumed on tire contact patch has not been clarified. Therefore, we studied “micro” tire slip power dissipation mechanism using tire brush model that is widely used to calculate tire generation force. The analysis result shows the power is dissipated only in the slip region and the amount is equal to the “macro” input power. The consistency between energy source and sink of vehicle-tire dynamics was proved theoretically.
