Abstract:

The auxiliary brake in a commercial vehicle is used to prevent the main brake from rupturing or not working by overheating. Contactless electronic brakes are developed as auxiliary brakes, and current-utilization increases the control accuracy. However, continuous charges and discharges of a battery due to the use of large amounts of current would shorten the battery life and could decrease the braking efficiency of a contactless brake.
This paper proposes a method to utilize the braking torque efficiently when an alternator creates a current by using diodes to distinguish the currents of a battery and an alternator and to extend the battery life by decreasing the number of charges and discharges of a battery. By implementing the controller and making the test bed, discharge of a battery has been prevented and stable operation of the electronic brake has been made.
