AI Technical Summary

Technical Problem

Existing fuel anti-theft measures for commercial vehicles suffer from high costs, complex installation, low level of intelligence, high false alarm rate, and lack of multi-dimensional alarm methods.

Method used

By integrating a fuel level sensor, alarm execution unit, vehicle remote communication unit, and anti-theft filter cartridge into the cockpit domain controller, multiple alarm methods are combined. Compensation is performed using vehicle attitude information from the inertial measurement unit. Intelligent power management and isolation structure are adopted to provide dual protection for both hardware and software.

Benefits of technology

It reduces hardware costs and installation complexity, enables local and remote three-dimensional early warning, reduces false alarms, ensures system reliability and high integration, and provides both physical and electronic anti-theft measures.

Abstract

This utility model discloses a commercial vehicle fuel anti-theft system based on a cockpit domain controller, comprising: a fuel level sensor, a cockpit domain controller, and an alarm execution unit. The cockpit domain controller integrates a main control unit, a real-time clock chip, and a non-volatile storage unit. After the vehicle is turned off, the system enters a low-power arming mode. The real-time clock chip periodically wakes up the main control unit to compare the current fuel level with the baseline value stored during arming. If an abnormal decrease occurs, an alarm is issued through the alarm execution unit. The alarm execution unit includes an instrument / central control display screen and an in-vehicle remote communication unit, enabling local and remote cloud-based alarms. The cockpit domain controller employs a structure that isolates security and entertainment functions to ensure the reliability of the anti-theft function. This utility model features high structural integration, comprehensive functions, and strong reliability, effectively improving the fuel asset security of commercial vehicles.
