Abstract: In this disc brake, a pair of brake pads has recesses in the outer peripheral surfaces thereof. A pad spring has a first pressing section extending axially and provided to a base, the first pressing section pressing, toward the trailing side, a first section to be pressed which is provided on the trailing-side side surface of side surfaces which form the recess of a brake pad—and which are raised outward in the radial direction of a rotor. Also, the pad spring has a second pressing section extending axially and provided to the base, the second pressing section—pressing radially inward on the bottom surface of the recess of each of the pair of brake pads, the bottom surface being a second section to be pressed which is provided on an outer peripheral section.

Abstract: A behavior control apparatus for a vehicle having a control unit for controlling a braking device and controlling a behavior of a vehicle by controlling braking forces of wheels. When the vehicle is in the non-braking state, the control unit acquires information on a lateral acceleration of the vehicle; calculates, based on the lateral acceleration of the vehicle, a target yaw moment of a feedforward control for reducing a rate of decrease of the vehicle's yaw gain accompanying with an increase in an absolute value of a lateral acceleration of the vehicle, and controls braking forces of the wheels by controlling the braking device so that at least a yaw moment corresponding to the target yaw moment is applied to the vehicle.

Abstract: A brake control device to be applied to a vehicle having a hydraulic brake generating a hydraulic braking force, which is a braking force converted from a fluid pressure to a wheel of the vehicle, and an electric parking brake generating an electric braking force, which is a braking force different from the hydraulic braking force, on the wheel by a wheel brake mechanism driven by a motor. The brake control device includes an electric parking brake controller for determining a current target value, which is a target value of an electric current through the motor, by using a target braking force, and for controlling the electric parking brake by using the current target value. The electric parking brake controller is configured to estimate the fluid pressure in the hydraulic brake by using a current detection value, which is a detection value of an electric current through the motor.

Abstract: A vehicle brake device includes a stroke simulator, a stroke sensor, and a brake start determination unit. The stroke simulator includes a cylinder, a piston, an orifice, and a pressure sensor. The cylinder defines a liquid pressure chamber to which a brake liquid is supplied via a fluid path. The piston slides in the cylinder by the brake liquid supplied to the liquid pressure chamber. The orifice is formed in the fluid path. The pressure sensor detects a reaction pressure. The stroke sensor is configured to detect the stroke. The brake start determination unit determines an operation of the brake operation member has been started in a case where the reaction pressure detected by the pressure sensor becomes equal to or greater than a first threshold value and the stroke detected by the stroke sensor becomes equal to or greater than a second threshold value.

Abstract: This brake control device includes: an operation amount sensor which detects the brake operating member operation amount; front-wheel and rear-wheel actuators which generate braking force in front/rear wheels; front-wheel and rear-wheel sensors which detect the outputs of the front-wheel and rear-wheel actuators; and a controller which controls the front-wheel and rear-wheel actuators based on the operation amount and the outputs of the front and rear wheels. On the basis of the operation amount and/or the output of the rear wheels, the controller determines whether or not a long-term low-load state in which the friction member is continuously pressed against the rotary members of the rear wheels within a predetermined range over a long period of time is established. If so, the distribution ratio of the rear-wheel braking force to the total applied braking force is decreased compared to when a long-term low-load state is not determined to be established.
