Abstract: A friction material for a brake pad comprises a fibrous base material without a metal fiber, and comprises a binder and a friction modifier. The friction material comprises 0.3% to 2.0% by weight, relative to the entire friction material, of a non-crosslinkable polyolefin having a melting point higher than the melting temperature of the binder. The friction material can suppress increase in friction coefficient of a friction material during initial brake operation and reduce the occurrence of abnormal effects and squealing in low-temperature and high-humidity environments.

Abstract: The electric parking brake control device performs accelerator release control for moving a friction-applying member to a standby position when a vehicle starting operation is performed, the standby position being positioned between a locked position and a released position such that friction-applying member moves from the standby position to the locked position within a time which is shorter than a time required to move from the released position to the locked position. The electric parking brake control device determines whether it is unnecessary to maintain the standby position, based on whether a state in which a vehicle speed exceeds a specific speed threshold value is maintained for a predetermined period of time. The release control is performed when the electric parking brake control device determines that it is unnecessary to maintain the standby position.

Abstract: This electric braking device uses drive torque of an electric motor to push a friction member against a rotating member secured to a vehicle wheel and produce braking torque in the vehicle wheel. This device comprises a body power source for electric motor power supply secured to a body of the vehicle, and a vehicle wheel power source for electric motor power supply secured to the vehicle wheel. The body power source supplies power to the vehicle wheel power source via a first electric path, and the vehicle wheel power source supplies power to the electric motor via a second electric path. When braking torque is produced in the vehicle wheel, the electric motor is normally driven using the vehicle wheel power source. An electric braking device is thereby provided in which a power line electrically connecting the body side and the vehicle wheel side bends readily.

Abstract: A vehicle braking control device includes: an indicated-value-setting unit for setting an indicated current value, which relates to a differential pressure valve provided to a channel between a master cylinder and a wheel cylinder, to a value corresponding to a required differential pressure; and a depressurization-starting differential pressure acquisition unit for acquiring, as a depressurization-starting differential pressure, the differential pressure at the point in time when a pressurizing state for increasing the differential pressure caused by the differential pressure valve transitions to a depressurizing state for reducing the differential pressure caused by the differential pressure valve. The area between the depressurization-starting differential pressure and a boundary differential pressure is set as a depressurization-starting differential pressure area. When the depressurizing state is in effect and the required differential pressure is included in the depressurization-starting differential pressure area, the indicated-value-setting unit sets the slope of decrease of the indicated current value.

Abstract: To enable control of vehicle speed according to the intentions of a driver by a simpler operation. When a vehicle body speed rapidly decreases and becomes lower than a brake target threshold speed, the brake target threshold speed is decreased in conformity with the vehicle body speed. This prevents the increase of the vehicle body speed toward the brake target threshold speed such that a vehicle accelerates regardless of a brake being in operation because the brake target threshold speed is set at a higher value than the vehicle body speed. Accordingly, the vehicle body speed decelerates by a simpler operation while being able to prevent the vehicle from accelerating against the intentions of a driver and being able to control the speed of the vehicle according to the intentions of the driver.
Abstract translation: 通过简单的操作，可以根据驾驶员的意图来控制车速。 当车体速度快速降低并且变得低于制动目标阈值速度时，制动目标阈值速度根据车体速度而减小。 由此，制动目标阈值速度设定为比车体速度更高的值，能够防止车体速度朝向制动目标阈值速度的增加，使得车辆加速而不管制动器是否在运转。 因此，能够通过简单的操作使车体速度减速，同时能够防止车辆抵抗驾驶员的意图而加速，并且能够根据驾驶员的意图来控制车辆的速度。
