A vehicle brake system and a method of control. A friction brake torque and a secondary brake torque may be applied with a friction and secondary brakes, respectively, under various operating conditions, such as when a brake torque command is less than a threshold brake torque command.

Brake system and method of control

A system and method of controlling pressure of a tire. The method may include executing a low supply pressure operating mode when an available supply pressure of pressurized gas is less than a target tire pressure. The tire may be inflated with pressurized gas provided at the available supply pressure when an estimated tire pressure is not within a threshold amount of the available supply pressure.

Tire inflation system and method of control

A tire inflation system and a method of control. A tire pressure sampling interval may be triggered based on a type of tire pressure drop, wheel speed, or temperature.

A tire inflation system and a method of control. An inflation pressure of a tire may be checked when a tire pressure sampling interval has elapsed. The tire pressure sampling interval may be adjusted based on a type of pressure drop when the inflation pressure is less than a target tire pressure.

A tire inflation system and a method of control. Tire inflation pressure may be adjusted based on a target tire pressure that may vary with vehicle load.

A system and method of determining wear of a wheel seal assembly. A warning indicative of wear of the wheel seal assembly may be generated when a wheel speed exceeds a threshold wheel speed for first amount of time, when a tire pressure exceeds a threshold tire pressure for a second amount of time, and/or when a wheel end temperature exceeds a threshold wheel end temperature for a third amount of time.

System and method of monitoring wheel end seal assembly wear

An air suspension system is configured to adjust and maintain a desired vehicle ride height and spring rate. The air suspension system includes a plurality of air spring assemblies that each include a piston airbag and a primary airbag mounted around the piston airbag. A controller receives ride height input data and adjusts pressures within the primary and piston airbags until the desired ride height and spring rate is achieved. The controller accommodates for system hardware differences by varying flow rates into and out of the primary and piston airbags relative to each other.
