Abstract
An air supply control arrangement for a heavy-duty vehicle including a lift axle which includes a brake chamber. The air supply control arrangement includes a valve configured to be arranged in an air supply passage that enables pressurized air to be supplied from a pressurized air source to a brake chamber of a lift axle of a heavy-duty vehicle; a processing circuitry configured to receive measurement values of the pressure inside a tire of the lift axle, wherein the processing circuitry is configured to, based on the received measurement values, determine whether the lift axle is in its raised lift condition or in its lowered ride condition, wherein the processing circuitry is configured to control the valve to move to a closed state upon determination that the lift axle has been raised from its ride condition to its lift condition, thereby preventing pressurized air from reaching the brake chamber.
