Abstract: Methods and systems are provided for controlling a suspension system of a vehicle. In one embodiment, the method includes: receiving, by a processor, sensor data indicative of conditions of a roadway in a path of the vehicle; determining, by a processor, a continuous road profile based on the sensor data; and selectively controlling, by a processor, at least one suspension element of the vehicle based on the continuous road profile.

Abstract: A method for determining a tire tread wear estimation of a tire includes receiving, by a controller, a direct tire tread wear measurement, when available, performing an indirect tire tread wear estimation, performing a data fusion of the indirect tire tread wear estimation with the direct tire tread wear measurement when available, estimating a percentage tire life remaining and a mileage to end of tire life, and estimating a refined tire tread wear calibration coefficient for performing future indirect tire tread wear estimations.

Abstract: A vehicle includes a frame, a body supported by the frame, a prime mover mounted to the frame, at least one axle connected to the frame, a suspension system connecting the at least one axle to the frame, and a load sensing and control system including at least one load sensor connected to the suspension system and a controller operatively connected to the at least one load sensor and the prime mover. The controller being operable to calculate a vehicle loading factor before the vehicle moves and to prevent operation of the prime mover if the vehicle loading factor that exceeds a selected load threshold.

Abstract: A suspension system for a vehicle includes a plurality of air spring assemblies, each having an air spring, and a suspension position sensor; and a controller. The controller is programmed to determine corner forces associated with each air spring of the plurality of air spring assemblies based on a pressure provided by a pressure sensor and an effective area of each air spring of the plurality of air spring assemblies based on a total length provided by the suspension position sensor, according to a target total length of each air spring.
