31/

Vehicle fittings for automatically controlling vehicle speed, i.e. preventing speed from exceeding an arbitrarily established velocity or maintaining speed at a particular velocity, as selected by the vehicle operator (B 60 K 41/00 takes precedence; propulsion-unit control in general, see the relevant classes or subclasses, e.g. F 02 D; speedometers G 01 P; systems or devices for controlling speed in general G 05 D 13/00) [2]

Note

In this group:

–

the means ordinarily includes a device, e.g. a servomechanism, for operating a velocity-affecting element of the vehicle, e.g. the throttle;

–

a means for preventing a vehicle from exceeding a particular speed is often referred to as a "governor", whereas a means for maintaining the vehicle within a relatively narrow speed range is generally designated as "speed control". Since these two functions are frequently interrelated, no attempt has been made to identify such means as being particularly adapted to perform only one, or the other of the functions. [4]

31/

including electrically actuated servomechanism [4]

31/

and means for comparing one electrical quantity, e.g. voltage, pulse, waveform, flux, or the like, with another quantity of a like kind, which comparison means is involved in the development of an electrical signal which is fed into the controlling means [4]

31/

including fluid pressure actuated servomechanism [4]

31/

and one or more electrical components for establishing or regulating input pressure [4]

31/

and means for comparing one electrical quantity, e.g. voltage, pulse, waveform, flux, or the like, with another quantity of a like kind, which comparison means is involved in the development of a pressure which is fed into the controlling means [4]

31/

including a device responsive to centrifugal force [4]

Notes

(1)

This subgroup covers also, for example, the pendulum of a curve compensator, i.e. a refinement to the regulating means for automatically adjusting the "set" speed of the means to changes in the course of the roadway along which the vehicle is travelling. [4]

(2)

In this subgroup, rotating weights driven at a speed proportional to that of the vehicle's motor presently predominate. [4]

31/

having an electrical switch which is caused to function by the centrifugal force [4]

31/

having means to prevent or discourage unauthorised use or adjusting of the controlling means [4]

31/

including a device to audibly, visibly, or otherwise signal the existence of unusual or unintended speed [4]

41/

Conjoint control of drive units; Conjoint control of at least two sub-units thereof (arrangement or mounting of plural diverse prime-movers for mutual or common propulsion B 60 K 6/00) [2,5]

Notes

(1)

The control of a single sub-unit is classified in the relevant class for the sub-unit. 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 class for this sub-unit. For instance, the control of variable-ratio gearing by means of signals from the engine or the accelerator is classified in subclass F 16 H. [5]

(2)

Conjoint control of drive units, e.g. propulsion units, and variable-ratio gearing occuring only transiently during ratio shift and being also characterised by the control of the gearing is classified in subclass F 16 H. [5]
