Abstract: Provided is an electric brake including: a brake mechanism configured to transmit, based on a braking request, a thrust force generated through drive of an electric motor to a piston configured to move brake pads to be pressed against a disc rotor; and an ECU for rear electric brake configured to control the drive of the electric motor, and to move, in a non-braking state, the piston to a predetermined clearance position at which a clearance between each of the brake pads and the disc rotor is a predetermined amount. The ECU for rear electric brake is configured to drive the electric motor so that a period from generation of the braking request to a start of the pressing of the disc rotor by the brake pads is a predetermined period regardless of a position of the piston at a time when the braking request is generated.

Abstract: In one embodiment, a system determines a signal fault at a communication bus of an autonomous driving vehicle (ADV). In response to determining the signal fault, the system sends a brake pre-charge command to a brake system of the ADV to pre-charge a brake of the ADV. The system determines a preset tolerance time to validate the signal fault. In response to a time elapse of the preset tolerance time, the system validates the signal fault at the communication bus or determine a signal fault at another communication bus. In response to validating the signal fault at the communication bus or determining the signal fault at the another communication bus, the system sends a brake command to the brake system of the ADV to engage brakes for the ADV.

Abstract: In one embodiment, the invention provides a method for controlling a vehicle brake system while the vehicle is in reverse. The method includes prefilling the brake system upon detecting an object in the vehicle's path. If the vehicle continues to move toward the detected object and a first threshold is reached, light braking is applied. If the vehicle continues to move toward the detected object and a second threshold is reached, heavier braking up to full braking is applied to prevent the vehicle from colliding with the object.

Abstract: Methods of assessing driver behavior include monitoring vehicle systems and driver monitoring systems to accommodate for a driver's slow reaction time, attention lapse and/or alertness. When it is determined that a driver is drowsy, for example, the response system may modify the operation of one or more vehicle systems. The systems that may be modified include: visual devices, audio devices, tactile devices, antilock brake systems, automatic brake prefill systems, brake assist systems, auto cruise control systems, electronic stability control systems, collision warning systems, lane keep assist systems, blind spot indicator systems, electronic pretensioning systems and climate control systems.

Abstract: Methods and apparatus for braking may control a brake between three states. Methods and apparatus for braking may comprise a sensor for sensing information about a brake input device, may comprise a brake control system coupled with the brake and the brake input device, and may control the brake based on the sensed information and input to the brake input device. Methods and apparatus for braking may control the brake to engage a friction material with a rotor if the brake input device indicates the brake should be engaged, and to remove the friction material from contact with the rotor if the brake input device indicates the brake should not be engaged. Methods and apparatus for braking may determine a condition of imminent braking based on the sensed information and may control the brake to enter a ready-to-engage state accordingly.

Abstract: A brake controlling unit detects a brake actuation object based on images captured by a running environment recognizing unit and sets a target brake pre-pressure actuation distance based on a relative speed between the brake actuation object and a subject vehicle. When an actual distance between the subject vehicle and the brake actuation object reaches the target brake pre-pressure actuation distance, the brake controlling unit outputs to a brake driving unit a driving signal that generates a brake pre-pressure to make the brake clearance of a brake minimal.

Abstract: A method is provided for operating an electromechanical vehicle brake system having an ESP module and at least two brake circuits, each brake circuit comprising high and low pressure switching valves, a low pressure storage device, and two wheel brakes. The method comprises, in advance of a possible breaking procedure and based on a trigger factor, filling the low pressure storage device with an amount of brake fluid at a first pre-pressure. Subsequently, an ESP pump is used to fill the vehicle brake system, including the low pressure storage device, with an adjustable amount of final pre-pressure. All valves are closed when the final pre-pressure is achieved. The method further comprises, during a braking procedure, opening respective inlet valves of the wheel brakes and supplying at least a part of the final pre-pressure to at least one wheel brake of the vehicle brake system.

Abstract: In a method for displacing and storing brake fluid for a hydraulic brake system of a vehicle which brake system has at least one hydraulic accumulator, at least one brake booster and at least one brake circuit, the brake booster is configured in such a manner, that even without an action of the driver, actuation of the brake booster allows a volume of brake fluid to be automatically displaced. The brake fluid is displaced into the hydraulic accumulator and stored, by automatic actuation of the brake booster, and at least a portion of the stored brake fluid is emptied by the hydraulic accumulator into the brake circuit as a function of the operating state of the brake system.
