An all-terrain vehicle is disclosed having a braking system with an anti-lock braking control module and a first brake master cylinder hydraulically coupled to the anti-lock braking control module. A first brake actuator is coupled to the first brake master cylinder and a brake caliper is coupled to at least some of the ground engaging members. The first brake master cylinder upon actuation provides anti-lock braking to either the first or second ground engaging members. A second brake master cylinder is hydraulically coupled to the anti-lock braking control module. A second brake actuator is coupled to the second brake master cylinder and a brake caliper is coupled to at least some of the ground engaging members. The second brake master cylinder upon actuation provides anti-lock braking to either the first or second ground engaging members. The vehicle also has a speed monitor with a gear ring positioned on an exterior surface of a stub shaft and a speed pickup positioned adjacent to the gear ring.

A cuboidal hydraulic block of a hydraulic unit of a hydraulic power vehicle braking system. The cuboidal hydraulic block is for fastening optionally with one fastening side or an opposite fastening side to a splashboard of a motor vehicle, so that the hydraulic unit may be housed optionally with an electric motor on a right side or a left side of the hydraulic block in an engine compartment of the motor vehicle.

A pressure medium assembly, in particular for providing and regulating a pressure in a brake circuit of a slip-controllable brake system of a motor vehicle, includes a housing block and an electronic controller. The housing block includes a pump configured to be actuated by a drive motor and a valve, which are actuated by the controller. The controller is secured to an outer face of the housing block and has a device flange that is paired with a housing flange formed on the housing block. The flanges fix the housing block and the controller together. The housing flange protrudes radially outwards relative to a housing block peripheral side facing the housing flange such that the entire upper face of the housing block is available for a controller housing. This configuration additionally allows the use of a printed circuit board which is free of open recesses on the peripheral side.

An electronic control unit for controlling a vehicle part is provided herein. The electronic control unit comprises a housing. The housing has an exterior surface and mounting elements on the exterior surface. The mounting elements are adapted for fastening the housing to a structure of a vehicle.

A holding assembly for securing a flange part which is provided on a braking device on an bulkhead of a motor vehicle, which bulkhead divides an engine compartment from a vehicle interior, wherein a holding plate is fastened on the side of the bulkhead facing the engine compartment and is provided with a form-locking connection that engages with the flange part.

An ABS disposition structure of a saddle riding vehicle includes a head pipe, a main frame, a pair of left and right center frames extending downward from a rear section of the main frame and having a pivot section by which a front end portion of a swing arm is pivotably supported, a cushion disposed at a center in a vehicle width direction, and an ABS modulator configured to perform ABS control, wherein, when seen in a side view, a central axis of the cushion is disposed to be offset from a center frame in a forward and rearward direction, and the ABS modulator is disposed between the cushion and the center frame in a vehicle width direction.

The invention obtains a hydraulic pressure controller whose control of a braking force is suppressed from becoming unstable. The invention also obtains a hydraulic brake system that includes such a hydraulic pressure controller, and a bicycle.
