VEHICLE BRAKE CONTROL SYSTEMS OR PARTS THEREOF

**Definition:** This place covers:

Arrangement of braking elements on vehicles (as defined in the Glossary of terms below).

Portable devices for preventing unwanted movement of vehicles, and especially where the devices are specially adapted to engage an exterior portion of a stationary vehicle to prevent or restrain its movement, e.g. chocks.

Vehicle modifications to facilitate cooling of brakes.

Control systems or parts thereof, in general or specially adapted for vehicles, for processing variables which influence the extent or duration of a braking event, for the following purposes:

Component parts, details or accessories of brake control systems, for example:

Component parts, details or accessories presenting other characteristic features, e.g. arrangements of pumps or compressors, brake cylinders other than ultimate actuators, safety or monitoring devices.

**Glossary:** - boosters: means for providing power assistance to the braking effort - vehicle: This term can have two different meanings here, viz. (1) all vehicles except those restricted to one of the following types of vehicles: rail vehicles, waterborne vessels, aircraft, space vehicles, hand carts, cycles, animal-drawn vehicles, and sledges, which are covered by the relevant subclasses of B61 - B64 . The term "vehicle" also includes (i) vehicular characteristics which are common to more than one of the above-listed types, and (ii) certain characteristics restricted to automobiles, road or cross-country trailers.(2) In some instances in this definition, the term "vehicle" has been qualified by another word which takes its meaning outside the scope of (1) above (e.g. "rail vehicle"), in which case the word "vehicle" takes its normal dictionary meaning. The reader can determine from the context whether an occurrence of the word "vehicle" in this definition falls within the meaning stated in (1) or (2).
