Abstract: Devices, systems, and methods for controlling a vehicle are described. An example method for controlling a vehicle includes obtaining planning information relating to an intended operation of the vehicle, the intended operation relating to an intended value of an operation parameter of the vehicle; obtaining, based on the intended operation of the vehicle, context information relating to an environment in which the vehicle is to operate following the planning information; determining a context compensated control instruction based on the planning information and the context information; obtaining feedback relating to a deviation of a real-time value of the operation parameter of the vehicle operating according to the context compensated control instruction from the intended value of the operation parameter relating to the intended operation; determining a corrected control instruction based on the feedback; and operating the vehicle based on the corrected control instruction.

Abstract: Devices, systems, and methods for predictive anti-lag braking control for autonomous vehicles are described. An example method of controlling a vehicle includes receiving, from a controller, a first plurality of values indicative of a brake wheel torque demand associated with a deceleration profile of the vehicle, deriving, based on the first plurality of values and a steady-state brake model, a second plurality of values indicative of a brake pressure demand, wherein an input to the steady-state brake model comprises the brake pressure demand and at least one previous brake wheel torque demand, and wherein an output of the steady-state brake system comprises a current brake wheel torque demand, generating, based on the second plurality of values and at least the steady-state model, a plurality of brake control commands, and controlling, using the plurality of brake control commands, the air brake system.

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.
