The truck industry's primary focus is on global transportation, necessitating the efficient movement of goods and materials. There are many types of trucks designed for different purposes, and one of the most significant ones is the tractor trailer which offers great flexibility and can carry heavy loads. The tractor-trailer assembly unit consists of a complex integration of mechanical, electrical, and pneumatic connections, each serving a critical role in the overall functionality and performance of the vehicle. The disconnection of electrical interconnections between the truck trailer and tractor is crucial to prevent damage to the connectors within the wiring harness, which can lead to hazardous situations on the road. The tractor unit serves as the power source, while the trailer is responsible for carrying cargo, with the wiring harness being a crucial yet vulnerable component.
When the trailer disengages from the fifth wheel coupling, it is vital to ensure that the electrical connections, which control lighting and trailer brakes, are also properly disconnected to prevent damage and potential safety risks. The proposed system employs advanced sensor technologies and intelligent algorithms to continuously monitor the status of these electrical connections. In the event of a disconnection, the system activates a robust alarm mechanism to promptly notify the driver, thus mitigating the risk of accidents and ensuring the safety of both the vehicle and other road users.
This paper presents a Trailer-Tractor Disengage Alarm System (TTDAS) designed to enhance safety in the electrical connections between the tractor and trailer of commercial vehicles. Key features of the TTDAS include real-time monitoring, rapid response times, and compatibility with various trailer configurations. The paper details the system architecture, encompassing the integration of sensors, control units, and the alarm mechanism. Additionally, the paper explores the algorithmic logic utilized to accurately detect trailer disengagements, thereby enhancing the reliability of the system.
