Philosophy of conjoint control in subclass B60W :

**Limiting references (this place does not cover):** - Propulsion of purely electrically-propelled vehicles with power supplied within the vehicle -> B60L50/00 - B60L58/00

**Glossary:** - Automatic control: Control system for mechanising or assisting, to a full- or partial extent, tasks associated with driving of the vehicle, e.g. those normally carried out by the driver or those necessary to control the motion of the vehicle. - Auxiliary equipment: Subsidiary or supplementary device of the propulsion, transmission or other units of the vehicle, e.g. a pump for supply of pressure for the control unit. - Conjoint Control: Programmed or condition-responsive automatic controller on-board the vehicle, embodying control logic for plural vehicle sub-units and sends control signals to actuators of two or more vehicle sub-units, so that the sub-units act together to solve a particular problem, in order to improve stability, comfort or safety by managing the global dynamics of the vehicle, or in response to a particular driving condition. The control logic considers the plural vehicle sub-units simultaneously, however, the control signals need not be sent at the same time. - Conjoint control of diverse vehicle sub-units: Control of different sub-units within the same vehicle for those vehicles defined under note to class B60 , and of general applicability to different types of vehicles normally under the control of a human driver or autonomous driving system. - Cruise control: System for automatically controlling vehicle speed, which may include additional functions e.g. control of distance between vehicles, so-called "Adaptive Cruise Control" (ACC). - Drive control system: Electronic system in a road vehicle for automatically controlling the movement of that vehicle in order to take certain actions. - Driveline Clutch: Clutch used for purposes other than changing gear ratios. - Driving parameter: All input or output parameters of the road vehicle drive control systems, e.g. road specific parameters, driver or passenger related parameters, state variables of motion of the vehicle body or parameters related to the vehicle itself like load or weight of the vehicle. - Hybrid vehicle: Vehicles having two or more prime movers of more than one type, e.g. electrical and internal combustion motors, and that are either singularly or in combination used for propulsion of the vehicle. - Road Vehicle: Motorised vehicle for transportation on roads, e.g. an automobile, truck or bus. - Sub-Unit: One of the following vehicle systems: 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, energy storage means, fuel cells or auxiliary equipment.
