摘要： Resistance feedback is provided to a machine operator via a joystick configured to steer the machine. An electrically actuated magnetic feedback brake unit is associated with the joystick for selectively resisting movement of the joystick. Haptic feedback is provided by determining a machine speed at which the machine is travelling, mapping the determined machine speed to a corresponding joystick resistance value, and mapping the corresponding joystick resistance value to an actuation current. The electrically actuated magnetic feedback brake unit is then actuated at a current substantially exceeding the actuation current until a predetermined level of actuation is reached. Once the predetermined level of actuation is reached, the electrically actuated magnetic feedback brake unit is driven at the actuation current.
