Industry Challenges
Heavy-duty logistics fleets face several operational challenges that demand reliable in-vehicle hardware solutions.
Overload Risks
Manual estimation increases risk of violations and penalties
Limited Trailer Visibility
ABS status, air pressure, operating hours difficult to track
Harsh Vehicle Environment
Vibration, temperature extremes, unstable power supply
These conditions place high demands on in-vehicle hardware reliability, requiring industrial-grade solutions designed for continuous operation in demanding environments.
Solution Overview
The overall solution was developed and deployed by a fleet system integrator, integrating axle load sensors, trailer ECU data, and a fleet management software platform.
Within this architecture, rugged MDT tablets for fleet systems were deployed as the in-vehicle hardware platform, supporting real-time data display, stable system operation, and continuous communication between vehicle and backend systems.
System Architecture Overview
The MDT tablet serves as a central interface connecting GNSS positioning modules, CAN Bus / vehicle interfaces, trailer ECU systems, external sensors (e.g., load sensors), and fleet management software.
