The Vehicle Safety Monitoring System using the Controller Area Network (CAN) protocol is the powerful automotive safety solution designed for improvement in road safety. This system involves an array of sensors and microcontrollers to constantly monitor critical vehicle parameters, including engine temperature, vibrations, seat belt switch, door lock switch, and live location using GPS. Leveraging the efficiency and using the CAN protocol, it establishes a seamless communication network among vehicle components. When potential safety threats are detected, the system will provide real-time alerts to the driver through visual and auditory signals, and, in some instances, takes autonomous actions to mitigate risks. This innovative technology not only helps to prevent accidents but also stores and transmits essential data for post-incident analysis, ultimately leading to safer roads, reduced accidents, increased driver confidence, enhanced data accuracy, faster threat detection, lower response time, integrated vehicle diagnostics, improved safety compliance, and scalable network architecture.
