A brake fluid pressure control device for vehicles with bar handle which is configured to start a holding control of a fluid pressure of a wheel brake according to wheel deceleration calculated based on a wheel speed of the vehicle is provided. In the brake fluid pressure control device, the vehicle includes an acceleration sensor which is configured to detect acceleration in a front-rear direction of the vehicle, acceleration, detected by the acceleration sensor, which occurs in a rearward direction when the vehicle is decelerating is detected as a positive value, and the holding control is started when it is judged that the acceleration detected by the acceleration sensor is larger than or equal to a detection acceleration threshold value and the wheel deceleration is smaller than or equal to a wheel deceleration threshold value.

A braking control device comprising: an operation amount acquisition device that obtains an operation amount for a braking operation member; a pressurizing unit that presses a friction member to a rotating member fixed to a wheel using an electric motor; a control that controls output of the electric motor based on the operation amount; a pressing force acquisition device that obtains the actual pressing force of the friction member pressing on the rotating member; and a rotation angle acquisition device that obtains the actual rotation angle of the motor. The control: stores the correlation between the actual pressing force and the actual rotation angle; approximates a function map indicated by a second degree or higher polynominal, based on the correlation; calculates a target rotation angle based on the operation amount and the function map; and controls the electric motor to match actual rotation angle and the target rotation angle.

A braking control device applicable to a vehicle having an electric parking brake with a motor-driven wheel braking mechanism includes a control unit, an offset estimation unit, and an offset correction unit. Based on a target motor current value indicating a target value of current to be inputted to the motor and a detection value from a current sensor that detects the current to be inputted to the motor, the control unit controls the current to the motor such that the detection value equals the target motor current value. The offset estimation unit determines an offset estimation value indicating an estimated value of offset of the detection value from the current sensor, based on behavior of the vehicle after lock control at the time of the vehicle's stoppage. The offset correction unit corrects the target motor current value or the detection value based on the offset estimation value.

Aspects concern a method for controlling a braking of a vehicle. The method including detecting a braking situation, determining a classification of the braking situation, selecting a braking profile based on the determined classification, and applying a deceleration based on the selected braking profile to maintain a safety distance based on the selected braking profile.

A regenerative braking control method of a vehicle, may include a first operation of determining a driving risk of a road surface on the basis of a status of the road surface while driving; a second operation of determining whether an accelerator pedal is released while driving; a third operation of determining whether a brake pedal is operated while driving; and a fourth operation of performing no regenerative braking when the accelerator pedal is determined as being released, the driving risk of the road surface is determined as being high, and when the brake pedal is determined as not being operated.

A method is provided for operating a motor vehicle brake system that includes an actuatable brake master cylinder, a hydraulic brake booster, and at least one brake circuit that has at least one hydraulically actuatable wheel brake and at least one hydraulic-pressure generator driven by electric motor. The method includes monitoring a state of actuation of the brake master cylinder is monitored, and, upon detecting a maximum state of actuation, activating the hydraulic-pressure generator to increase the hydraulic pressure adjusted by the brake master cylinder in the brake circuit.

Detectable indicia are provided on the interior circumferential rim of the brake hub-drum adjacent to, and spaced apart from, the backing plate of the brake. A sensor is mounted on the backing plate to detect wheel speed and/or other operating conditions detectable from the motion and/or relative location or condition of those indicia. The number of indicia used and the indicia spacing along the interior circumferential rim is selected as needed for a given type of sensor and/or a given application. In the case of a speed sensor, the indicia can be a series of notches in the rim along the entire interior circumferential rim, resembling a series of teeth into that rim. The width of those teeth can be formed wide enough to accommodate movement of the hub-drum relative to the backing plate and/or the sensor, without loss of system functionality, according to the sensing tolerances of a given sensor being used in a given application.

A braking control apparatus for a vehicle including: a pedal stroke sensing unit configured to sense a pedal stroke of a brake pedal; a pedal simulator pressure sensing unit configured to sense pressure of a pedal simulator that provides a reaction force in response to a stepping force of the brake pedal; and a control unit configured to apply different computation methods by selectively utilizing a pedal stroke STR sensed by the pedal stroke sensing unit and pedal simulator pressure P_SIM sensed by the pedal simulator pressure sensing unit at a plurality of stages defined while the brake pedal is pressed and released, and decide required braking pressure P which is required for braking the vehicle.

A brake system includes a service brake and a parking brake that brake a vehicle including a lift axle capable of ascending and descending. The brake system further includes a brake blocker device and a controller that controls the brake blocker device. The brake blocker device blocks at least one of supply of compressed air to the service brake and supply of compressed air to the parking brake. The service brake and the parking brake act on the lift axle. The controller actuates the brake blocker device when the lift axle is at a lifted position.
