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.

Abstract: A drive axle system and a method of control. A control system determines a torque command based on an inverter temperature, a stator temperature of a stator of an electric motor, and a rotor temperature of a rotor of the electric motor. The electric motor is operated to provide torque based on the torque command.

Abstract: A method of controlling a drive axle system. The drive axle system includes a first axle assembly and a second axle assembly that are electrically connected to the same electric power source or different electric power sources. The method operates the axle assemblies within power and current limits of an associated electric power source.

Abstract: A method of controlling a vehicle. The vehicle includes an axle assembly and a one-pedal driving system. The axle assembly may be operatively connected to an electrical machine that is configured to provide torque to a vehicle wheel. The one-pedal driving system that has a pedal that controls torque provided by the electrical machine.

Abstract: A method of controlling a drive axle system. The method may include executing a gear upshift or a gear downshift after decreasing the torque that is provided by an electric motor to a transmission of an axle assembly and increasing the torque that is provided by another electric motor to a transmission of another axle assembly.

Abstract: An axle assembly having a shift collar and a sensor. The shift collar may be rotatable about a first axis and moveable along the first axis. The sensor may detect detection features associated with the shift collar and provide a signal that may be indicative of rotation of the shift collar about the first axis and positioning of the shift collar along the first axis.

Abstract: An electrical control system is provided. A first slave IC generates a first message indicating that a first battery cell has an overvoltage condition that is received by a communication IC. The communication IC sets a fault line coupled between the communication IC and a secondary microcontroller to a first logic level indicating that an overvoltage condition has been detected. The secondary microcontroller sends a message to a primary microcontroller indicating that the overvoltage condition has been detected in response on the fault line having the first logic level. The primary microcontroller commands a contactor control system to set each of the first and second contactors to the open operational state, in response to receiving the message.

Abstract: An electrical control system having a primary microcontroller, a secondary microcontroller, a slave IC, and a communication IC is provided. The communication IC sets a fault line to a first logic level indicating that an overvoltage condition has been detected in a battery cell. The secondary microcontroller sends a message to the primary microcontroller via a communication bus indicating that the overvoltage condition has been detected in response to the fault line having the first logic level. The primary microcontroller determines that both the message from the second microcontroller was received and the fault line has the first logic level to confirm that the communication bus is functioning as desired and that the secondary microcontroller is functioning as desired.
