Abstract

The control strategy of regenerative braking energy is an important link in pure electric buses development. Because of the addition of motor braking in traditional mechanical braking basis, the total vehicle braking force under the same brake intention of drivers will vary, and this may change the braking comfort. Combining the maximum regenerative braking torque provided by motor and ECE braking regulations, the thesis chosen two regenerative braking control strategies, made modeling and simulation on them, and analyzed the braking comfort changes by them. Moreover, Regenerative braking control procedures have been writen by CoDeSys engineering software, carried out the tests, and compared the test data and simulation results.
