A control system for controlling the ride height of a vehicle, the system including a controller that receives and processes multiple variable inputs to provide enhanced ride height control. The inputs include a brake system signal including an Automatic Braking System (ABS) signal and/or an Electronic Braking System (EBS) signal, a remote setpoint signal and/or a fluid dump signal. The system also provides for measuring the actual ride height, filtering the measured ride height, determining if the filter ride height signal exceeds a threshold level, and adjusting the ride height accordingly.

A trim component for a vehicle interior includes first and second skin layers, a core layer sandwiched between the first and second skin layers with the core layer having first and second sides, a first thermoplastic adhesive material including a polyamide disposed between the first skin layer and the core layer to adhere the first skin layer to the first side of the core layer, and a second thermoplastic adhesive material including a polyamide disposed between the second skin layer and the core layer to adhere the second skin layer to the second side of the core layer.

Trim component for a vehicle interior

A Push To Connect (PTC) fitting cartridge for connecting to a pneumatic device, such as, an air brake or a height control valve, the PTC fitting cartridge including at least one protrusion positioned on an outer surface of the PTC fitting cartridge, which is provided to interact with an undercut positioned on an inner surface of a port. The undercut interacts with the protrusion to substantially eliminate stress on the surrounding material to reduce the chance of fraction thereof.

PTC fitting cartridge

A height control valve for use in a vehicle suspension system for controlling the ride height of the trailer, the height control valve provided with a universal mounting for allowing greater flexibility in the mounting of the height control valve to a vehicle frame, the height control valve also having a position indicator to aide an installer in aligning a valve element contained within the valve according to a selected mounting position.

Height control valve with universal mounting for a suspension system

A control system, primarily for use with a vehicle, which increases ride stability and minimizes cycling of the control system during normal operation of the vehicle by utilization of a restriction valve to restrict the fluid introduced into or exhausted from a fluid bag in response to a received control signal.

Air suspension system with supply air restriction valve

A trailing arm suspension for a vehicle. The trailing arm suspension having a height control system for controlling the ride height of the suspension relative to the vehicle. The height control system preferably comprises a motor driven height control valve.

Trailing arm suspension and height control system with motorized valve therefor

A height control valve for controlling the relative height between a vehicle frame and a trailing arm suspension. The height control valve comprises a housing defining an interior chamber and having an inlet port fluidly connecting to a source of pressurized air. An air spring port is provided in the housing for fluidly connecting to an air spring. Additionally, an exhaust port is provided in the housing for fluidly connecting to the atmosphere. A valve is disposed within the interior chamber and is selectively operable between a fill position, an exhaust position, and a neutral position.

Vehicle suspension system and height control valve therefor

An air suspension control system, primarily for use with a vehicle, which increases ride stability and minimizes air losses to the air suspension control system during normal operation of the vehicle by utilization of an air restriction valve to restrict the air introduced into or exhausted from an air spring in response to a received control signal.
