A vehicle includes an air compressor system for supplying compressed air to an air consuming circuit, wherein the vehicle includes an arrangement for determining that the vehicle is coasting. The compressor system is controllable to deliver compressed air at a first power rate and at least at a second higher power rate, and it is controlled to deliver compressed air at the second higher power rate when it is determined that the vehicle is coasting. A method for operating an air compressor system for such a vehicle is also provided.

1. Vehicle comprising an air compressor system having at least one compressor for supplying compressed air to an air consuming circuit, wherein the vehicle comprises means for determining that the vehicle is coasting, wherein the compressor system is configured to be controlled so that the compressor delivers compressed air at a first power rate and at least at a second higher power rate, and the compressor system is configured to be controlled so that the compressor delivers compressed air at the second higher power rate when the determining means determines that the vehicle is coasting. 2. Vehicle according to claim 1, wherein the compressor system comprises at least one compressor which is driven at a higher speed when the determining means determines that the vehicle is coasting. 3. Vehicle according to claim 2, wherein the compressor is driven by an electrical motor, the speed of the electrical motor being increased when the determining means determines that the vehicle is coasting. 4. Vehicle according to claim 2, wherein the compressor is driven through a variable speed ratio transmission, and the speed ratio of the transmission is increased when the determining means determines that the vehicle is coasting. 5. Vehicle according to claim 4, wherein the variable speed ratio transmission is a stepped gear transmission. 6. Vehicle according to claim 4, wherein the transmission is a continuously variable speed ratio transmission. 7. Vehicle according to claim 4, wherein the transmission comprises at least one planetary gear. 8. Vehicle according to claim 1, wherein the compressor system is a multistage compressor system where at least one unloadable stage of the compressor can be unloaded, so that the compressor system delivers air at a first lower pressure, or can be loaded so that the compressor system delivers air at a second higher pressure, and the unloadable stage is loaded when the determining means determines that the vehicle is coasting. 9. Vehicle according to claim 1, wherein the system comprises at least one variable capacity air compressor, and a capacity of the variable capacity compressor is increased when the determining means determines that the vehicle is coasting. 10. Vehicle according to claim 1, wherein the air compressor system is arranged to he controlled to operate at in at least three operating modes: an unloaded mode where it provides substantially no pressurized air, a normal mode where it delivers pressurized air at the first power rate, and an enhanced delivery mode where it delivers pressurized air at the second higher power rate. 11. Vehicle according to claim 1, wherein the vehicle comprises an electronic control system which, when the vehicle is coasting, controls the air compressor system at the second higher power rate, depending on a status of vehicle operating parameters. 12. Vehicle according to claim 1, comprising a thermal traction engine, an electrical traction motor, an electricity storing system, the electrical traction motor being able to recharge the electricity storing system when the vehicle is coasting, and at least one compressed air accumulating system, wherein the vehicle comprises an electronic control system which, when the vehicle is coasting, controls the air compressor system at the higher power rate, depending on the status of the electricity storing system. 13. Method for operating a vehicle air compressor system having at least one compressor, wherein the compressor system is configured to he controlled so that the compressor delivers compressed air at a first power rate and at least at a second higher power rate, wherein the method comprises determining whether the vehicle is coasting, andcontrolling the compressor system so that the compressor delivers compressed air at the second higher power rate depending on the status of vehicle operating parameters, including whether the vehicle is coasting. 14. Method according to claim 13, wherein the vehicle further comprises a thermal traction engine, an electrical traction motor, an electricity storing system, the electrical traction motor being able to recharge the electricity storing system when the vehicle is coasting, and at least one compressed air accumulating system, wherein the step of controlling the compressor system so that the compressor delivers compressed air at the second higher power rate depends on a status of the electricity storing system.
