Abstract

A prime mover, such as a tractor, is disclosed. The prime mover includes a drivetrain, a driver assistance system, and a tire pressure control system. The tire pressure control system is equipped with pneumatic components for setting and adapting a tire pressure of at least one of the tires of the prime mover and an attachment to the prime mover. The drivetrain includes at least one drive motor, one gearbox, at least one power take-off, and at least one ancillary unit. The driver assistance system controls the tire pressure control system and includes a computing unit, a memory unit, and an input/output unit. In particular, the driver assistance system includes an automatic tire pressure controller that operates based on a characteristic curve and is configured for optimized control of the tire pressure control system depending on selectable control strategies and/or optimization target variables.
