Abstract: Braking torque is automatically applied based on requested deceleration and requested distance from a driving assistance device. Standard deceleration decreases in an “upwardly curved” form and then decreases in a “downwardly curved” form over time in a standard deceleration profile, and a standard speed profile corresponds to the standard deceleration profile. In the present calculation period, target deceleration and target speed profiles are set by adjusting the standard deceleration/standard speed profiles to satisfy the relationship between deceleration and vehicle body speed. The estimated distance from the reference speed to the vehicle stop is calculated based on the target speed profile. In a condition that the estimated distance is equal to/less than the requested distance is denied, braking torque is adjusted based on requested deceleration. After first satisfying the condition that the estimated distance is equal to/less than the requested distance, braking torque is adjusted according to the target deceleration profile.

Abstract: A motion conversion mechanism of a brake device includes a rotation member and a linear motion member that linearly moves accompanying the rotation of the rotation member. The rotation member is rotationally driven through a third gear. A male screw and a female screw mesh with each other on the side opposite to the brake shoe of the third gear, where one end of an actuating member receives a force for actuating the brake shoe from the linear motion member, and the other end actuates the brake shoe. The guide member that guides the actuating member is made of a material different from that of the rotation member, and slidably guides the actuating member in the axial direction.

Abstract: A brake control device includes: a decrease determination unit that determines whether a requested braking force for a vehicle is decreasing; and a brake control unit which, on the condition that the decrease determination unit determines that the requested braking force is decreasing during deceleration of the vehicle, executes ratio change decrease control of reducing the braking force of the vehicle according to the decrease of the requested braking force, while making a braking force distribution ratio smaller than a reference braking force distribution ratio. The reference braking force distribution ratio is the braking force distribution ratio at a time point when the requested braking force starts to decrease.

Abstract: A braking control device includes an actuator, a controller, a steering angle sensor, and a yaw rate sensor. The controller calculates a reference turning amount, an actual turning amount, an understeer index, sets to a non-adjustment region in which the increase slope is not decreased when the understeer index is smaller than or equal to a first threshold value, sets to an adjustment region in which the increase slope is decreased when the understeer index is greater than or equal to a second threshold value greater than the first threshold value, and sets to a transition region in which the increase slope is decreased when the understeer index is transitioned from the non-adjustment region and the increase slope is not decreased when the understeer index is transitioned from the adjustment region when the understeer index is greater than the first threshold value and smaller than the second threshold value.

Abstract: The brake control device controls a hydraulic brake to generate hydraulic braking force on both the front and rear wheels of a four-wheel-drive vehicle, and an electrical parking brake to generate parking brake force, different from the hydraulic braking force, on the front or rear wheels. The brake control device includes: a detection unit that detects parking brake operation for causing the electrical parking brake to generate a parking brake force; and a control unit for reducing the hydraulic braking force generated on the front wheels or the rear wheels and adjusting the hydraulic braking force on the other of the front wheels or the rear wheels to a magnitude allowing a stationary vehicle state to be maintained, before a parking brake force is generated by the electrical parking brake, when a parking brake operation is detected while a stationary state is being maintained solely by the hydraulic braking force.

Abstract: A pad support spring includes a U-shaped portion comprising an outer peripheral surface portion, an inner peripheral surface portion and a linking surface portion. The U-shaped portion is configured to include: a pad holding portion; a cutout portion provided by cutting out a part from the linking surface portion toward the inner peripheral surface portion; a tongue piece portion which in an unassembled state has a base end formed by the cutout portion on the outer peripheral surface portion side of the pad holding portion and a distal end which projects out from an opposing surface of the inner peripheral surface portion, and which in an assembled state deforms elastically to press a brake pad in conjunction with the U-shaped portion; and a first slit portion provided by cutting out part of a first linking part.
