Development of servo-controlled braking system

Abstract

Today’s brake systems in cars are based on hydraulics. The company Kvaser aims to move away from the hydraulics and replace it with an electrical brake system controlled with a servo. Kvaser are specialists in communication based on the CAN-protocol (Controller Area Network). The communication within the current system is also based on this protocol. The purpose of this project is to develop a servo driven brake system for Kvaser. Multiple development tools have been used in this project such as Kvasers own CANDev and STM32CubeIDE created by STMicroelectronics. This paper is intended to be used as a quick guide to get an understanding of how the brake is built and how to modify it for future development. A test rig was constructed to measure the braking capabilities of the servo. The results showed that the servo was strong enough to withstand the weights used during testing and the configuration of the processor unit used to control the servo. Future plans for the car include an implementation of multiple synchronous servos with regulators and an anti-lock braking system
