  • Patent number: 10435005
    Abstract: A brake monitoring and adjustment control system includes an electromechanical brake actuator controller (EBAC) and at least one sensor operatively connected to the EBAC. The sensor is configured to sense a characteristic of a brake and provide a feedback signal to the EBAC. The system includes a switch for turning power to the sensor on and off to reduce the duration with voltage applied to the sensor. Reducing the duration in which voltage is applied to the sensor reduces power consumption and assists with mitigating electro-migration growth.

  • Patent number: 10407041
    Abstract: An electric parking brake actuator has a transmission mechanism, which is rotationally drivable by an electric motor and converts rotational movement into an axial movement of an actuating rod that carries an actuating element for the parking brake. The actuating rod normally moves by electric motor displacement via the transmission mechanism from an unblocking position to a blocking position and vice versa. A blocking mechanism serves the purpose of holding the actuating rod in the unblocking position of the actuating rod against the force of a spring element. A blocking disc, which is in drive connection with the transmission mechanism, has a stop surface for a locking device in only one rotational direction of the blocking disc. For secondary alternate operation the stop surface is releasable by the locking device so that the actuating rod is biased by the spring element to the blocking position without electric-motorized assistance.

  • Patent number: 9630508
    Abstract: A vehicle and a method for controlling regenerative braking may utilize the maximum available regenerative braking torque for some time during a braking event. As the vehicle speed and/or powertrain torque decreases, the regenerative braking torque is controlled to deviate from the maximum. The point at which the regenerative braking torque deviates from the maximum is chosen based on the level of vehicle deceleration. The regenerative braking torque is then smoothly blended out until it reaches zero. The regenerative braking torque is brought to zero when the vehicle speed is very low, thereby eliminating the inefficiencies associated with operating a motor at a very low speed.

  • Patent number: 9587692
    Abstract: The present teachings relate to a brake assembly, and more particularly to a differential for a brake assembly that is unlocked or open in one configuration and locked or closed in another configuration. The brake assembly comprises a differential and one or more output shafts. During rotation of at least one of the one or more output shafts a brake apply is created or released. During creation of the brake apply, the differential distributes a rotational force to each of the one or more output shafts until at least one of the one or more output shafts experiences higher resistance and then the differential re-distributes the rotational force to at least one of the one or more output shafts with lower resistance. During release of the brake apply, the differential distributes an opposing rotational force equally to each of the one or more output shafts.

  • Patent number: 9522659
    Abstract: A brake system includes an electric brake force generator which brakes a wheel using a driving force of an electric motor and an electric motor controller that performs a field-weakening control of the electric motor. The electric motor controller performs the field-weakening control of the electric motor which then operates the electric brake force generator. Thus, the rotational speed of the electric motor is increased when the field weakening control is performed by the electric motor controller thereby quickly activating the electric braking force generator to enhance response of brake force generation.
