Abstract
A method for controlling motion of a heavy-duty vehicle, the method including: obtaining input data related to one or more parameters of a tire on the heavy-duty vehicle, determining 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 wheel slip and generated wheel force, wherein the tire model is parameterized by the one or more tire parameters, and controlling the motion of the heavy-duty vehicle based on the relationship between wheel slip and generated wheel force.
Claims20
A method for controlling motion of a heavy-duty vehicle, the method comprising:
- obtaining input data related to one or more tire parameters on the heavy-duty vehicle,
- determining 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 wheel slip and generated wheel force, wherein the tire model is parameterized by the one or more tire parameters, and
- controlling the motion of the heavy-duty vehicle based on the relationship between the wheel slip and the generated wheel force by sending wheel slip requests from a vehicle motion management (VMM) function of the heavy-duty vehicle to one or more motion support device (MSD) control units of the heavy-duty vehicle.
