  • Patent number: 11433865
    Abstract: An electrically actuated parking brake has a single electric motor producing a torque, a first torque limiting device with a first spring force, and a second torque limiting device with a second spring force. The first torque limiting device fully transmits a first portion of the torque to a first spindle until a first clamp force overcomes the first spring force and the second torque limiting device fully transmits a second portion of the torque to a second spindle until a second clamp force overcomes the second spring force. When the first clamp force overcomes the first spring force and the second spring force overcomes the second clamp force, the first portion of the torque that exceeds the first spring force is transmitted to the second spindle by the second torque limiting device.

  • Patent number: 11332106
    Abstract: A master pressure control device of an electric booster sets an upper limit of current supplied to an electric motor in accordance with an operation amount of an input member to a current limit value A when a condition for limiting the driving of the electric motor is satisfied due to a decrease of voltage of a vehicle power source. The master pressure control device sets the upper limit of the current supplied to the electric motor in accordance with the operation amount of the input member to a current limit value B when the condition for limiting the driving of the electric motor is cancelled due to restoration of the voltage of the vehicle power source to normal while a brake pedal is operated. The current limit value B is larger than the current limit value A used when the driving of the electric motor is limited.
