Abstract
A method of controlling an axle assembly. The method includes executing a speed synchronization mode and operating a clutch actuator to shift a clutch from a neutral position toward an engaged position. The method may also include executing a low torque synchronization mode when the clutch cannot be shifted from a neutral position to an engaged position within a first predetermined period of time.
Claims20
A method of controlling an axle assembly, the method comprising:
- executing a speed synchronization mode that modifies a rotational speed of a rotor of an electric motor of the axle assembly while maintaining torque provided by the electric motor so that the rotational speed of the rotor becomes closer to a rotational speed of a clutch of the axle assembly, wherein the axle assembly has a transmission that has a set of gears, the electric motor provides torque to the transmission, the rotor is rotatable about an axis and is operatively connected to the transmission, the clutch is selectively engageable with a member of the set of gears, and a clutch actuator is configured to actuate the clutch;
- operating the clutch actuator to shift the clutch from a neutral position toward an engaged position;
- determining whether the clutch is shifted from the neutral position to the engaged position within a first predetermined period of time;
- and
- executing a low torque synchronization mode when the clutch is not shifted from the neutral position to the engaged position within the first predetermined period of time.
