Abstract
A heavy-duty vehicle includes a chassis, a wheel supporting the chassis, a drive system, a service brake, a drive system controller, and a service brake controller. The drive system includes a motor associated with the wheel. The motor is configured to propel the wheel and to apply a dynamic brake torque to the wheel. The service brake is associated with the wheel and configured to apply a service brake torque to the wheel. The drive system controller controls operation of the motor. The drive system controller selectively modulates the dynamic brake torque to the wheel based on traction conditions. The service brake controller controls operation of the service brake. The service brake controller may selectively modulate the service brake torque to the wheel based on the traction conditions. Modulation of the dynamic brake torque may be disabled during modulation of the service brake torque.
