A brake control device for a vehicle, includes: a master cylinder outputting a brake fluid of a master pressure; a master pressure changing device for changing the master pressure; a brake actuator for controlling a brake pressure of the brake fluid supplied from the master cylinder to a wheel cylinder; and a control device performing an automatic brake control including first and second modes. In the first mode, the control device operates the brake actuator to make a target value of the brake pressure. In the second mode, the control device operates the master pressure changing device such that the master pressure becomes the target value of the brake pressure to change the brake pressure of the target wheel in conjunction with the master pressure. The control device selects one of the first and second modes depending on a type of the automatic brake control.

The present invention relates to an electronic control unit (ECU) structure of a brake system. An ECU of a brake system, according to the present invention, has a redundancy configuration in which a first control unit, a first cover, and a second control unit are sequentially stacked so that the first control unit and the second control unit are spatially separated by means of the first cover, and thus the second control unit can perform the function of the first control unit without being influenced when the first control unit malfunctions.

A brake system includes a reservoir and first and second motor-driven master cylinders. An electronic control unit is provided for controlling at least one of the first and second master cylinders responsive to at least one brake pressure signal. A secondary power transmission unit is configured for selectively providing pressurized hydraulic fluid at first and second PTU outputs for actuating first and second pairs of wheel brakes in at least one of a normal non-failure braking mode and a backup braking mode. Each of the first and second PTU outputs provides fluid to a corresponding one of the first and second pairs of wheel brakes. The secondary power transmission unit is directly fluidly connected to the reservoir.

A an apparatus of controlling a braking of a vehicle traveling in track mode includes a driving information detector configured to detect a braking request from a driver while the vehicle is driving; and a vehicle controller configured to, when the braking request is detected, control the braking of the vehicle according to a total required torque in response to the detected braking request, wherein the total required torque is a sum of a regenerative braking torque by a motor of the vehicle and a friction braking torque by a brake of the vehicle, wherein the vehicle controller is configured to decrease braking force by friction braking by relatively decreasing friction braking torque by increasing the regenerative braking torque of the total required torque, and wherein the regenerative braking torque is greater than a regenerative braking torque in non-track mode.

Systems and methods are described for distributed electric park brake control. The vehicle's electronic stability controller (ESC) is configured to monitor the status of an electric parking brake switch and to provide control signals to a motor-on-caliper actuator based on the status of the electric parking brake switch. A secondary brake system controller (for example, a brake pedal booster unit) that is configured to control at least one function of the braking system that is not related to the parking brake function is further configured to determine whether the ESC is operating properly and, in response to determining that the ESC is not operating properly, to monitor the status of the electric parking brake switch and provide the control signals to the motor-on-caliper actuator based on the status of the electric parking brake switch.

A method and a system for decelerating a single-track motor vehicle, includes using a control unit to determine a total torque of a wheel of the motor vehicle required for a desired riding maneuver, in particular a controlled slip of a rear wheel, determine, a braking partial torque and a motor partial torque as a function of the total torque required, and generate the braking partial torque on the wheel by controlling a brake system of the motor vehicle and generating the motor partial torque on the wheel by controlling a motor of the motor vehicle The invention further includes a single-track motor vehicle configured to execute the decelerating method.

A method for controlling deceleration of a vehicle is provided. The vehicle has a braking system having a braking actuation lever, a braking actuator, and at least one braking device.
