摘要： A mount member is fixed to a support member by first and second fastening members, and a caliper is mounted to the mount member by first and second guide members. A motor axis of an electric motor and an axis of a shaft member configured to press a pressing member are different from each other. The electric motor is fixed to the caliper. When viewed from an axial direction of the first guide member, the motor axis is positioned inside a fastening quadrangle having four corners corresponding to positions of respective axes of, and is perpendicular to the axis, and the motor axis is orthogonal to a plane of the fastening quadrangle. As a result, there may be provided a vehicle electric braking device in which an axial direction dimension may be reduced to suppress an amplitude caused by vibration, and components sensitive to vibration influence are appropriately arranged.

摘要： A pedal bracket is divided into a main bracket and a sub-bracket. The main bracket and the sub-bracket are connected by a mounting bolt and a nut, the mounting bolt serving as a supporting shaft of a swing link which connects a brake pedal and a push rod. When an external force of a predetermined value or greater is applied to the front of the vehicle, an extending portion of the sub-bracket is pressed by the main bracket and swings substantially rearward of the vehicle and a clevis at the end of the push rod is forced in substantially toward the front side of the vehicle by a front surface of the extending portion. Accordingly, the brake pedal swings around a mounting bolt substantially toward the front side of the vehicle via the swing link and the like and a pedal pad is displaced substantially toward the front side of the vehicle.

摘要： In a vehicle brake control device for generating rear wheel braking torque by an electric motor, “slip suppression control of the rear wheel” for reducing rear wheel braking torque by controlling the electric motor is executed based on a slip state quantity of the rear wheel. Further, “sudden-stop control” for rapidly stopping electric motor rotation motion is executed based on a slip state quantity of a front wheel. The sudden-stop control is executed when rear wheel slip suppression control is not being executed. As the sudden-stop control, “control for changing an energization amount of the electric motor stepwise to an energization limit value set in advance corresponding to a deceleration direction of the electric motor” may be executed. Accordingly, it is possible to suppress excessive rear wheel slip due to inertia influences or the like of the electric motor when execution of the rear wheel slip suppression control is started.
摘要翻译： 在用于通过电动机产生后轮制动转矩的车辆制动控制装置中，基于后轮的滑动状态量来执行用于通过控制电动机来减小后轮制动转矩的“后轮的滑移抑制控制”。 此外，基于前轮的滑动状态量来执行用于快速停止电动机旋转运动的“突然停止控制”。 当不执行后轮打滑抑制控制时，执行突然停止控制。 作为突然停止控制，可以执行“将电动机的通电量逐步改变为对应于电动机的减速方向而设定的通电限制值的控制”。 因此，当执行后轮打滑抑制控制开始时，可以抑制由于电动机的惯性影响等导致的过大的后轮滑动。
