Abstract
A method for controlling motion of a heavy-duty vehicle includes obtaining input data related to one or more tire parameters of a tire on the heavy-duty vehicle, estimating at least part of the one or more tire parameters based on the input data, configuring a tire model, wherein the tire model defines a relationship between tire wear rate and vehicle motion state, wherein the tire model is parameterized by the one or more tire parameters, estimating vehicle motion state, and controlling motion of the heavy-duty vehicle based on the tire model and on the vehicle motion state.
Claims21
A method for controlling motion of a heavy-duty vehicle, the method comprising
- obtaining input data related to one or more tire parameters of a tire on the heavy-duty vehicle,
- estimating at least part of the one or more tire parameters based on the input data,
- configuring a tire model, wherein the tire model is parameterized by the one or more tire parameters,
- estimating a vehicle motion state, and
- controlling motion of the heavy-duty vehicle based on the tire model and on the vehicle motion state,
- wherein the tire model defines a relationship between tire wear rate and vehicle motion state, and
- wherein controlling motion of the heavy-duty vehicle based on the tire model and on the vehicle motion state comprises
- estimating, based on the tire wear model, respective resulting tire wear rate from different control strategies for the vehicle motion state, and
- selecting one of the different control strategies, wherein the selected control strategy is associated with an acceptably low tire wear.
