Patent attributes
An improved system for braking an agricultural vehicle propelled by a hydrostatic drive unit is disclosed. An operator provides a desired speed command from a first user interface, such as a joystick. The joystick generates a command responsive to the deflection and communicates the command to a controller. The agricultural vehicle also includes a second user interface, such as a brake pedal. The brake pedal includes a transducer configured to generate a signal corresponding to a deflection of the brake pedal which is also communicated to the controller. If the operator presses the brake pedal when the joystick is commanding motion, the controller reduces the signal from the joystick. The amount the signal is reduced increases as the deflection of the brake pedal increases until the brake pedal overrides any speed command from the joystick.
