Patent number: 9815446Abstract: The operation of an air compressor is controlled to control engine performance to thereby improve the performance of the vehicle. A compressor (4) driven by an engine (3) of a vehicle and supplying compressed air to loads (51-54) is controlled by an ECU (2). A loaded state and an unloaded state of the compressor (4) are switched between each other according to the requirements from the loads (51-54). When the vehicle requires braking force, the compressor (4) is set to the loaded state irrespective of the requirements from the loads (51-54).Type: GrantFiled: April 15, 2015Date of Patent: November 14, 2017Assignee: Nabtesco Automotive CorporationInventors: Ichiro Minato, Hiroki Hasebe
