sentences:  The brake actuator has an electric pump that provides the hydraulic pressure for the system, and valves to pressurize each wheel caliper to apply the friction brake when required by the system.The system includes all of the complexity of a vehicle stability control system (VSC), antilock brake system (ABS), and the requirement to use the Regeneration Braking as the primary mode of slowing the vehicle unless the Traction Battery (high-voltage battery) state of charge is too high to accept the additional energy or a panic stop or ABS situation is detected by the system.The sensors monitored as inputs for the brake system include the wheel speed sensors, 
  traction battery state of charge, yaw sensor, brake pedal, stroke sensor, steering wheel angle, hydraulic actuator pressure, hydraulic pressures of each wheel caliper circuit, and accelerator position.
