1. A heavy-duty vehicle comprising:
a chassis;
a wheel supporting the chassis;
a drive system including a motor associated with the wheel, wherein the motor is configured to propel the wheel and to apply a dynamic brake torque to the wheel;
a service brake associated with the wheel and configured to apply a service brake torque to the wheel;
a drive system controller configured to control operation of the motor, wherein the drive system controller selectively causes the motor to apply modulated dynamic brake torque to the wheel based on traction conditions, and wherein the drive system controller selectively causes the motor to apply unmodulated dynamic brake torque to the wheel based on traction conditions; and
a service brake controller configured to control operation of the service brake,
wherein the service brake controller selectively causes the service brake to apply modulated service brake torque to the wheel based on the traction conditions, and wherein the service brake controller selectively causes the service brake to apply unmodulated service brake torque to the wheel based on the traction conditions, and
wherein while the service brake applies modulated service brake torque, modulated dynamic brake torque is disabled and unmodulated dynamic brake torque is allowed.
