Abstract

The present disclosure relates to a braking system and, more particularly, to a braking system for engaging a brake mechanism as a waiting brake for a load carrying vehicle. The braking system comprises first and second brake mechanisms. A controller is configured to control the operation of the second brake mechanism such that, if a predetermined fault condition is determined whilst the first brake mechanism is engaged, the controller automatically engages the second brake mechanism.

First claim

1 - 5 . (canceled)

6 . A braking system for a vehicle comprising:
a first brake mechanism; a second brake mechanism; and a computer control unit configured to control operation of the second brake mechanism, wherein if a predetermined fault condition associated with the vehicle, other than a determination of a failure of a component of the first brake mechanism, is determined whilst the first brake mechanism is engaged, the computer control unit automatically engages the second brake mechanism.

7 . A braking system as claimed in claim 1 in which the computer control unit is configured to control the operation of the first brake mechanism and disengage the first brake mechanism when the second brake mechanism is engaged.

8 . A braking system as claimed in claim 1 in which the computer control unit is configured to receive signals from at least one electronic control unit monitoring the operation of the vehicle.

9 . A braking system as claimed in claim 1 in which the predetermined fault condition associated with the vehicle other than a determination of a failure of a component of the first brake mechanism comprises any one of:—
a failure of a vehicle component other than a component of the first brake mechanism;
a failure of a vehicle system or sub-system;
speed of a vehicle engine of the vehicle dropping below a threshold speed;
the vehicle engine shutting down; and
a ground speed of the vehicle being above a pre-set minimum ground speed.

10 . A braking system as claimed in claim 4 in which the ground speed of the vehicle is determined by a transmission output speed being above a pre-set minimum speed for a pre-set minimum period of time.
