Abstract
Devices, systems, and methods for estimating wheel torque in an autonomous vehicle include a method for controlling a vehicle includes using a dual filter framework to generate an updated estimate of a wheel torque, and controlling, based on the updated estimate of the wheel torque, the vehicle. A first filter of the dual filter framework is configured to generate a blended estimate of the wheel torque by combining a first estimate of the wheel torque that is generated based on a set of mechanical torque transfer models of at least a powertrain and a brake of the vehicle and a second estimate of wheel torque that is generated based on an inverted longitudinal dynamic model, and a second non-linear filter of the dual filter framework is configured to generate the updated estimate of a wheel torque and vehicle velocity based on a torque delivery damping process model on vehicle motion.
