摘要：An Electrical Vehicle (EV) has the advantage of being friendly with environment but it does not
have the same performance as a current conventional vehicle. This work proposes a strategy to
improve the EV autonomy. At first, an EV model that combines lead acid batteries and a DC
motor is described. The individual mathematical model for each component is developed in
MATLAB. Moreover, the control speed strategy using fuzzy logic is applied to the system to
produce a maximum speed reference of an EV under different states of charge of the battery
and acceleration. Then, a proportional integral control adjusts the speed strategy. When the
vehicle is subjected to different scenarios, the simulation realized in MATLAB/Simulink will
show good efficiency.
