The invention relates to a
simulation system for dynamic property of a pure electric automobile. The
system is characterized by comprising a battery module, a
motor module, a whole vehicle module, a controller module, a cycle working condition module and a display module, wherein the whole vehicle module also comprises a
brake module which comprises an attachment sub-module; and the controller module performs control by using PWM chopping. The
system simulates the working conditions of flat ground, climbing and cycle based on
matlab software. The
simulation system for the dynamic property of the pure electric automobile not only can perform analog
simulation on three indexes of the dynamic property of the automobile, namely the maximum speed, the acceleration capacity and the maximum climbing capacity, but also can perform the analog simulation on the cycle working condition so as to predict the
driving range of the automobile; and the system also can perform the analog simulation on the braking condition of the automobile so as to predict the minimum
braking distance and braking time of the automobile; therefore, a user can optimize the optimal
transmission ratio of the automobile by using a matrix
operation mode so as to improve the dynamic property and the
driving range of the automobile.
