B60W
CONJOINT CONTROL OF VEHICLE SUB-UNITS OF DIFFERENT TYPE OR DIFFERENT FUNCTION; CONTROL SYSTEMS SPECIALLY ADAPTED FOR HYBRID VEHICLES; ROAD VEHICLE DRIVE CONTROL SYSTEMS FOR PURPOSES NOT RELATED TO THE CONTROL OF A PARTICULAR SUB-UNIT
NOTE
-
(1) This subclass does not cover the control of a single sub-unit; such control is classified in the relevant place for the sub-unit, e.g. F02D, F16H. Where a single sub-unit is controlled by means of signals or commands from other sub-units, the control of this single sub-unit is classified in the relevant place for this sub-unit. For example, the control of variable-ratio gearing by means of signals from the engine or the accelerator is classified in the subclass for gearing, F16H.
(2) Conjoint control of driveline units, e.g. engines, and variable-ratio gearing occurring only transiently during ratio shift and being also characterised by the control of the gearing is also classified in the subclass for gearing, F16H.
(3) In groups B60W 20/00 - B60W 50/00, the first place priority rule is applied, i.e. at each hierarchical level, classification is made in the first appropriate place.
(4) When classifying in group B60W 10/00, classification must also be made in groups B60W 20/00-B60W 50/00 in order to identify the purpose or use of the control.
(5) In this subclass, the following terms are used with the meanings indicated:
- "conjoint control" means that a programmed or condition-responsive
{
main
}
 automatic controller on board the vehicle, embodying control logic for vehicle sub-units of different type or different function, sends control signals to actuators of two or more vehicle sub-units,
{
three or more vehicle sub-units for groups B60W 30/00-30/16
}
, so that the sub-units act together to solve a particular problem or in response to a paticular driving condition,
{
in order to improve stability, comfort or safety by managing the global dynamics of the vehicle
}
;
- "drive control system" means an electronic system in a road vehicle for automatically controlling the movement
{
by managing the global dynamics
}
 of that vehicle in order to take certain actions
{
in order to improve stability, comfort or safety
}
;
- "road vehicle" means a
{
motorised passenger
}
 vehicle normally under the control of a human driver for transportation on roads, e.g. an automobile, truck or bus;
- "sub-unit" means one of the following vehicle systems:
{
driveline systems, e.g.
}
 propulsion system, clutch system, change-speed gearing system, system for distributing drive torque between front and rear axles, axle differential system, brake system, steering system, suspension system,
{
and, particularly for hybrid vehicles,
}
 energy storage means, fuel cells, or auxiliary equipment.
