Embodiment Construction
[0011] Referring to the drawings, an air management system 20 for controlling an air suspension assembly of a motor vehicle having a body and four wheels is generally shown. Additionally, a method of operating the air management system 20 is disclosed.
[0012] Such as figure 1 As best represented in , the air management system 20 is connected to a pair of front air springs 22 interconnecting the vehicle's body and front wheels and a pair of rear air springs 24 interconnecting the vehicle's body and rear wheels. The air springs 22, 24 dampen the relative forces between the body and the wheels and raise and lower the motor vehicle to a desired height.
[0013] The air management system 20 includes: a compressor 26, shown generally, connected to the air springs 22, 24 to provide pressurized air for filling the air springs 22, 24; a manifold block 28, which The manifold block 28 has a plurality of valves 34, 36, 40, 42, 46, 48 for controlling which air springs 22, 24 are filled...

An air management system and method of operating the same to reduce the starting torque of a compressor. An air management system and method are provided. The system includes a compressor and an accumulator tank coupled to the compressor. A manifold block has a plurality of valves and is coupled to the reservoir tank and the compressor for controlling gas flow. At least one pressure sensor is coupled to the manifold block. The compressor includes a boost valve for selectively connecting the accumulator tank directly to the air inlet of the compressor. An electronic control unit is connected to the valve, compressor and at least one pressure sensor and is configured to provide pressurized air from the reservoir tank to the air inlet, determine the difference between the manifold block and the boost valve and, in response to the pressure differential being less than a predetermined amount, maintaining pressure in the manifold block to reduce the starting torque of the compressor without venting the manifold block.
Description
technical field [0001] The present disclosure relates to an air management system for controlling an air suspension assembly of a motor vehicle. More specifically, the present disclosure relates to an air suspension control system including a manifold and a compressor and a method for canceling manifold exhaust noise when the compressor is activated. Background technique [0002] Air suspension assemblies are known in the art for motor vehicles. Such air suspension assemblies typically include a plurality of air springs, each for interconnecting the body with one of the wheels of the motor vehicle, for damping relative forces between the body and the wheels, and for adjusting the the height of the vehicle. [0003] To control such air suspension components, an air management system is usually used. Air springs are typically connected to the manifold of the air management system via one or more air lines. The air management system may also include a compressor, or a pump ...
