Vehicle Velocity Calculation Using Wheelbase Time Difference

The patent applies the dynamics principle by transitioning from a static assumption (fixed pitch effect position at the median) to a dynamic solution (detecting the actual pitch effect position through sensor measurements). The system dynamically identifies whether the pitch angular velocity causes effect on the front wheels, rear wheels, or median by measuring vertical accelerations and pitch angular velocity, and selects the appropriate calculation equation accordingly. This resolves the contradiction by maintaining calculation simplicity through automated position detection while ensuring accuracy by adapting to the actual vehicle state.

The patent applies the universality principle by creating a velocity calculation system that can handle multiple vehicle configurations (two-wheeled, three-wheeled, and four-wheeled vehicles) through a unified approach. The system uses vertical acceleration sensors and pitch angular velocity sensors to detect the actual pitch effect position, then selects from multiple equations (Equations 2-4) appropriate for different vehicle types. This universal system maintains high accuracy across all vehicle configurations by automatically adapting to the specific vehicle structure through sensor-based position detection and conditional equation selection.
