    Abstract: A method for detecting a fail of an electronic parking brake may include: detecting, by an electronic control unit (ECU), a current applied to a motor during a parking operation of an eDIH parking brake, and detecting a current inflection point at which the slope of the current is changed, the slope of the current having started to rise in a load generation section following a no-load section after a starting current of the motor was generated; and comparing, by the ECU, the current value of the detected current inflection point to a current value of a preset reference current inflection point, and recognizing that a fail occurred during the parking operation of the eDIH parking brake, when the current value of the detected current inflection point is different by a preset error range or more from the current value of the reference current inflection point.

  • Patent number: 10737673
    Abstract: An electric-brake controller includes an antilock controller configured to control a pressing force of an electric brake. The electric brake includes a pressing member that is advanced by rotation of an electric motor in a forward direction to press a friction member against a brake rotation member. The electric brake includes a return spring that applies a spring force such that the pressing member is moved away from the brake rotation member. The antilock controller includes a pressing-force reducer that reduces the pressing force. The pressing-force reducer includes: a reverse-rotation-current supplier that supplies reverse-rotation current for rotating the electric motor in a reverse direction for a reverse-rotation-current supply time; and a forward-rotation-current supplier that supplies forward-rotation current, for rotating the electric motor in the forward direction, to the electric motor after the reverse-rotation current is supplied for the reverse-rotation-current supply time.

  • Patent number: 10668810
    Abstract: A method and system are provided for vehicle stabilization of a hybrid vehicle in an event of brake slip of the drive wheels or an increased risk thereof. The method presupposes that the hybrid vehicle includes, between the internal combustion engine and the electric motor, a clutch by which the torque of the internal combustion engine can be decoupled from the drive wheels. With the clutch engaged, the resulting torque on the electric motor is produced by the torque of the internal combustion engine and the torque of the electric motor. The presence of a specific vehicle condition indicative of brake slip of the drive wheels or a risk thereof is recognized. If such a vehicle condition is recognized, the clutch between the internal combustion engine and the electric motor is released and the torque of the electric motor is increased.
