A brake system to couple between brakes and actuators provides a modular format that allows a plurality of braking modules to be coupled together at interfaces and coupled to other modules to handle a variety of different braking scenarios. Each braking module includes a housing forming a manifold for the delivery of fluid to the interfaces of the modules for exchange between the modules. The braking modules include a hydraulic valve coupled with a pressurized fluid source for delivering fluid to implement a braking function. The modules also include an electro-hydraulic valve configured for receiving electrical input signals and configured for delivering fluid from the pressurized fluid source to the hydraulic valve at an actuation pressure that is proportional to the system pressure based on the levels of the received electrical input signals. Module interfaces are positioned on respective sides of the housings for coupling the braking modules together and include a repeated pattern of apertures for aligning between the braking modules. The aligned apertures are configured for passing fluid at the system pressure and fluid at the tank pressure between the plurality of braking modules.

A brake system may include an actuating device, in particular a brake pedal; a first piston-cylinder unit having two pistons subjecting the brake circuits to a pressure medium via a valve device, wherein one of the pistons can be actuated by the actuation device; a second piston-cylinder unit having an electric motor drive, a transmission at least one piston to supply at least one of the brake circuits with a pressure medium via a valve device; and a motor pump unit with a valve device to supply the brake circuits with a pressure medium. The brake system may also include a hydraulic travel simulator with a pressure or working chamber which is connected to the first piston-cylinder unit.

A method for controlling a hydraulic brake system for a motor vehicle to carry out a braking operation by means of at least one wheel brake includes, in a first step, a pressure buildup in the wheel brake, wherein hydraulic fluid is passed to a wheel brake via a normally open inlet valve. In a second step, a pressure reduction takes place in the wheel brake, wherein hydraulic fluid is discharged from the wheel brake via an energized normally closed outlet valve. The pressure reduction at the wheel brake is accomplished by means of control of the outlet valve in a predefined manner.

In a method, a brake torque signal provided by an electronic control unit of an anti-lock braking system is validated. The brake torque signal is enabled for use as a brake event input signal upon being successfully validated for diagnostic and control routines of the vehicle that use the brake torque signal as a brake event input signal. If the brake torque signal fails validation, it is disabled for such use. The brake torque signal is validated by first rationalizing a brake pedal position signal and a master cylinder pressure signal. Once the brake pedal position signal is successfully rationalized with the master cylinder pressure signal, the brake pedal position signal is rationalized with the brake torque signal. The brake torque signal is successfully validated when both rationalizations are successful. The validation fails if either rationalization fails.

A method of operating an anti-lock braking system (ABS) of a bicycle comprising steps of: judging whether a power of a battery meets a set value; judging a moved angular position of a brake lever; outputting electric currents to operate the ABS; and judging whether a running speed of the bicycle is zero. When the power meets the set value, the ABS is turned on, and when the power of the battery is low, the ABS is not turned on. After the brake lever is pressed, the control unit judges whether the moved angular position of the brake lever reaches a set position. When the moved angular position does not reach the set position, the ABS is not turned on. When the moved angular angle reaches the set position, the ABS is turned on. The control unit outputs the electric currents to turn on the ABS, thus braking the bicycle.

An ESC 33 increases distribution of a braking force to rear wheels according to a reduction in a speed of a vehicle due to braking, and distributes the braking force so as to allow the vehicle to be kept stopped due to braking forces applied to the rear wheels when the vehicle stopped. Then, a second ECU holds the braking force by driving a parking mechanism with the vehicle kept stopped due to the braking forces applied to the rear wheels.

A motion control system for controlling one or more torque generating devices on a heavy-duty vehicle, the system comprising a primary sensor system with a primary sensor control unit configured to interpret an output signal of the primary sensor system, one or more tire sensor devices mounted on, in, or in connection to, one or more tires of the heavy-duty vehicle, and a tire sensor control unit configured to interpret an output signal of the one or more tire sensor devices, wherein the motion control system is arranged to base motion control of the heavy-duty vehicle on output data of the tire sensor control unit in case of malfunction in the primary sensor system and/or in the primary sensor control unit, and on output data of the primary sensor control unit otherwise.

A composite cable includes a pair of first electric wires, a twisted pair wire formed by twisting a pair of second electric wires having a smaller outer diameter than the first electric wires, a tape member wound into a spiral around an assembly that is formed by twisting the pair of first electric wires and the twisted pair wire together, and a sheath covering an outer periphery of the tape member. The tape member and the sheath includes an inwardly projecting part formed in a spiral along a cable longitudinal direction and formed so as to enter inward at least one of a valley part between the two first electric wires and valley parts between the first electric wires and the twisted pair wire. The inwardly projecting part has a projecting length of not less than 3% of an outer diameter of the first electric wires.

An off-road vehicle has two front wheels and two rear wheels, the rear wheels being connected to a spool gear driven by a motor. The vehicle also has a left front brake, a right front brake and a single rear brake. Speeds of left and right front wheels are respectively monitored by left and right front speed sensors. A single sensor monitors a common speed of left and right rear wheels. Two user actuated braking input devices, for example a hand lever and a foot lever, may be used independently or concurrently to provide a braking command. An anti-lock braking system may use speed measurements from the various speed sensors to control selective application of pressure on the left front brake, the right front brake and the rear brake.

A method for adjusting brake pressures of a motor vehicle. The method includes actuating, by a control unit, while taking into account determined dynamic state variables of wheels that are to be braked, a pressure control valve with an inlet valve for ventilating and with an outlet valve for venting a brake pressure line that is controlled by the pressure control valve. The control times of the outlet valve are determined depending on control of the inlet valve. In an external braking mode provided for a case where an external braking demand is received that is independent of a driver's braking demand, the control unit adjusts the brake pressure in the brake pressure line according to the external braking demand by determining control times of the outlet valve depending on control of the inlet valve.
