Method and system for determining electric vehicle weight at a loading spot using electric torque-derived inclination angle and suspension fluid pressure data.

Patentradars sammanfattning

Volvo Autonomous Solutions AB discloses a computer-implemented method and system for accurately determining the total weight of an electric vehicle during loading operations. The approach derives a longitudinal inclination angle from the electric torque required to hold the vehicle stationary at a loading spot, and a transverse tilt angle from the differential fluid pressure across left/right suspension devices, both measured before loading. Post-loading suspension pressure data is then combined with these pre-determined angles to compute the total vehicle weight, compensating for site-specific terrain geometry without requiring external infrastructure.
