Abstract:
BLDC motors are used in Electric Vehicles(EV) due
to their low maintenance requirement, small size, high efficiency,
large starting torque and low noise operation. Anti-lock Braking
system(ABS) has been an important safety feature in traditional
vehicles. While applying brakes, ABS prevents the wheels from
getting locked and keeps the steering in driver’s control; thereby
reducing accidents. This paper proposes a simple method to
control BLDC motor for implementing ABS in EV using a
combination of Regenerative Braking, short-circuit braking and
mechanical braking while requiring no extra ABS sensors. This
method will improve the range of EV along with ensuring driver’s
safety. MATLAB-SIMULINK environment has been used to do
the simulations and the results of the same are discussed in this
paper.
