Investigation of vehicle energy demand considering the modified tire power loss

Owing to current status of global energy consumption and greenhouse gases emission, investigation of energy demand in different sectors seems to be necessary. Meanwhile, International Energy Agency  reports imply that a considerable share of global energy use is consumed in transport sector. Thus, conducting the vehicle energy demand and influential parameters has become a demanding topic, especially in recent years. The current study investigates the vehicle energy demand considering the power losses due to tire slip. To achieve this, vehicle resistant powers are rewritten by taking the modified tire power loss into account and after that, two different passenger vehicles are chosen and simulations are performed in three well-known driving cycles. Energy demand of the selected vehicles significantly increases in a more aggressive driving cycle which comprises higher levels of longitudinal acceleration and speed. According to the results, considering the power loss due to tire slip would improve the calculation accuracy of tire losses up to 6 percent and in case of a more aggressive driving cycle and/or increased resistant forces, energy loss due to tire slip would be increased.
