Development of Low-Cost Autonomous Emergency Braking System (AEBS) for an Electric Car

This paper presents the development of a low-cost Autonomous Emergency Braking System (AEBS) that can assist the driver or take over the electric car prototype for slowing down and breaking the car at the low-speed condition. An Actuator of AEBS is selected from DC motor that widely found on the market. The proposed AEBS is placed under the hood of the car. The AEBS will pull the brake pedal by using a Bowden cable. Ultrasonic sensor will be used for measuring the distance between the electric car and obstacle. On-off control will be developed for controlling the AEBS in breaking the electric car when the obstacle is approaching. After the AEBS prototype has been built, it will be employed in the electric car and tested for the automatic braking system. Based on the test results, the proposed AEBS can slow down and brake the car before colliding with the obstacle. The AEBS system will be activated when the distance between the car and the obstacle is less than 3.6 m. Based on the test result, AEBS can slow down and brake the electric car before colliding with the obstacle.
