20230150525 · 2023-05-18 ·

A dynamic sensor model is implemented by a vehicle to adapt sensor behavior to vehicle modifications and transformations. Responsive to impairment of a feature of the vehicle due to initial conditions for a target sensor being outside a range of current readings and further to receiving signals indicative of a upfit to the vehicle, an upfit zone of the vehicle is identified. The upfit zone corresponds to the target sensor. One or more reconfigurations of sensors of the vehicle within the upfit zone are performed to address the impairment of the feature.
