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.

Methods of assessing driver behavior include monitoring vehicle systems and driver monitoring systems to accommodate for a slow reaction time, attention lapse and/or alertness of a driver. 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 response system can modify the control of two or more systems simultaneously in response to driver behavior.

Abstract:
Systems and methods for reducing transient brake caliper drag in a motor vehicle are provided. The motor vehicle, for example, may include, but is not limited to, an axle, a rotor coupled to the axle, a brake caliper comprising a brake pad configured to engage the rotor, a brake pedal assembly communicatively coupled to the brake caliper, the brake pedal assembly configured to receive user input directing the brake pad to apply a force to the rotor and user input directing the brake pad to disengage the rotor, and a processor coupled to the brake caliper, wherein the processor is configured to determine, after the brake pedal assembly receives user input directing the brake pad to disengage the rotor, the force applied to the rotor, and command the brake caliper to retract the brake pad away from the rotor when the determined force exceeds a predetermined threshold.
Abstract:

Abstract:
A brake booster includes an input element actuatable by a driver, an actuator for generating a support force, an output element to which an input or support force may be applied and via which an actuating force may be applied to a piston of a brake master cylinder, and a force transmission unit having elastic properties, situated between the input element and the actuator, and the output element, and transmitting the input and/or support forces to the output element. An air gap, which in idle mode is smaller or larger than a desired air gap, is provided between the input element and the force transmission unit. A method for operating the brake booster includes generating a support force prior to a braking intent to be anticipated or immediately after detection of a braking intent, in a time span before or immediately after detection of an actuation of the input element.

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.
Abstract:
The invention relates to a driver assistance system for a vehicle, in particular commercial vehicle, wherein the driver assistance system (14) has: a detection system which has at least one sensor (15-1, 15-2, 15-3) for issuing measuring signals (S5-1, S5-2, S5-3), a control unit (16) for receiving the measuring signals (S5-1, S5-2, S5-3) and for determining the probability of a critical situation or critical state of the vehicle (1), wherein, when a critical state or sufficient probability of a critical state is identified, the control unit (16) of the driver assistance system (14) outputs a signal (S6) for priming a brake system (4) to a brake control device (6) of the brake system (4) of the vehicle (1), and wherein the control unit (16) outputs an external brake request signal (S6) for initiating braking operations to the brake control device (6) of the brake system (4). According to the invention, in order to prime the brake system (4), the control unit (16) outputs an external brake request signal (S6) which has a desired acceleration value signal (S6-3) with a higher desired acceleration value (a-des) than a current actual acceleration value (a-act).
