Abstract:
A vehicle includes a drivetrain and multiple motors. The drivetrain includes at least one wheel, and is mechanically connected to the motors. The vehicle additionally includes multiple control modules communicatively connected to the motors. The control modules include a power control module per motor. Each power control module is assigned a motor, communicatively connected to the assigned motor, and configured to operate the assigned motor. In response to a traction event, the control modules are configured to switch from a drive mode to a traction control mode. In the drive mode, the power control modules are configured to operate the respective assigned motors to contributorily satisfy at least one propulsion demand global to the vehicle. In the traction control mode, one of the control modules is configured to operate the motors to contributorily satisfy at least one propulsion demand global to the vehicle.
