Abstract

This report presents the development of an active braking system for a go-kart. The active braking system is a noble invention where its benefit is significant to improve driving safety and to save human life during an emergency situation. The development of this electromechanical brake system is significant to the progress of the automobile technology towards the eco-friendly or green technology, as the electromechanical braking system mitigates the usage of hydraulic fluid; whereby common problems such as improper disposal of used hydraulic fluid or leaked hydraulic fluid pollutes our environment. Besides, driving safety of a vehicle greatly improves when active braking system such as anti-locking brakes, traction control system and vehicle stability control is implemented in a vehicle. The active braking system is implemented by designing an electromechanical braking system. The basic requirement of an active braking system is that actuators component in the system has to be electrically powered and controlled using electronic controllers. The electromechanical brake system consists of a linear actuated stepper motor as the brake actuator, an Arduino Uno R3 as the brake system microcontroller, IR coupling sensor as the wheel speed sensor and a potentiometer as the brake pedal, whereby certain conventional brake components such as brake disc and brake pads are being used as well. The linear actuated stepper motor must be able to provide strong thrust force and quick response time for a good braking performance. The brake caliper assembly has to be light weight and easy to assemble or disassemble for regular maintenance work. An IR sensor coupling is used to provide signal pulses for wheel speed measurement for the Anti-locking Brake System (ABS) and wheel slip control (TRC) that was implemented in the active braking system. To achieve the objective of this project, an active braking system for a go-kart will be developed and a test bench will be fabricated to test the completed electromechanical braking system.
