Abstract
An in-vehicle compression device includes: a compressor including a cylinder and a piston that is slidably provided inside the cylinder and defines a compression chamber; a linear motor including a movable element reciprocatably connected to the piston; and a controller configured to control driving of the linear motor. The in-vehicle compression device is configured to supply a working fluid compressed in the compression chamber to a pressure device provided in a vehicle. The controller is configured to variably adjust a stroke of the piston according to a state of the vehicle.
