However, these vehicles cannot achieve the desirable autonomy due to reduced battery capacity. Other parameters that can increase or reduce the vehicle's electrical consumption are their aerodynamics, and transmission system, among others. KIT has a battery-powered passenger vehicle (Mercedes Benz A-Class) that has already been developed through other works, along with simulation models programmed in the IPG CarMaker software. In this dissertation, the vehicle simulation model was developed regarding the tire and chassis model to investigate its influence on electrical energy consumption and driving dynamics. The simulations were divided into three cases of study: dynamics of safety conducting, dynamic driving and economic driving. To assess safety during conduction, it was considered to analyse the influence of two active safety systems: ABS and AEB. The first allows the wheels to not block during a braking, providing a smaller braking distance and bypassing obstacles. The AEB monitors the road and if it detects an obstacle where it is necessary to stop, but the driver doesn't do so, it stops autonomously. The dynamic driving was tested with the ESP, whose purpose is to help the vehicle strengthen the loss of traction on the road. And with the analyse of the steering wheel angle behaviour. In last case of study, and within the tire sector and its different characteristics that could influence vehicle consumption, the following factors were evaluated: tire pressure, 2.2 bar and 2.9 bar, the coefficient of resistance, whose difference is obtained by choosing tires with different velocity ratings, Q and H. Lastly, extra loads were defined that would influence the vertical force that is applied to the wheels. These loads were considered in view of the occupancy of the vehicle only with the driver, in another case, occupied with 4 users.engCarro ElétricoPerdas de EnergiaPressão dos PneusResistência de RolamentoBateriaTeses de mestrado - 2024master thesis203878868
