Abstract
Abstract Control apparatus comprising a lever, foot pedal or other operating member which is coupled to an electrical stepper motor operable, under the control of a computer say, to generate detents and feel forces resisting the movement of the member and thereby impart information to the operator. For example, a detent or position of marked resistance can be introduced into the movement range of say a car throttle pedal to indicate to the driver a pedal position giving optimum economy of fuel. The detent position can be changed within the overall range of pedal movement in dependence upon instant driving parameters such as speed. As well as detents, programmed and/or external condition dependent feel forces can be generated.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
174 words
A control device for controlling associated equipment, the control device comprising a fixed support (1), a manually movable control member (5), output means (14) for transmitting a control action to said associated equipment dependent upon the position of the control member, an electrical stepper motor connected between the control member and the fixed support, and a computer for energising said motor to generate a controlled feel force resisting the manual movement of the control member and/or a noticeable increase in resistance to movement of the control member through one or more discrete detent positions in its overall range of movement, characterised in that the control member (5) is an elongate lever pivotably connected to the support (1) and said motor is a linear stepper motor with a fixed elongate stator (7) connected to the support and mover (9) supported by the stator for linear movement therealong and pivotably connected to the control lever at a position on the control lever spaced from that of its pivotable connection to the support (Figures 5 and 6).
Claim 2
Dependent Claim
174 words
A control device for controlling associated equipment, the control device comprising a fixed support (1), a manually movable control member (5), output means (14) for transmitting a control action to said associated equipment dependent upon the position of the control member, an electrical stepper motor connected between the control member and the fixed support, and a computer for energising said motor to generate a controlled feel force resisting the manual movement of the control member and/or a noticeable increase in resistance to movement of the control member through one or more discrete detent positions in its overall range of movement, characterised in that the control member (5) is an elongate lever pivotably connected to the support (1) and said motor is a linear stepper motor with a fixed elongate stator (7) connected to the support and mover (9) supported by the stator for linear movement therealong and pivotably connected to the control lever at a position on the control lever spaced from that of its pivotable connection to the support (Figures 5 and 6).
Claim 3
Dependent Claim
65 words
A control device according to claim 1, wherein said support (1) takes the form of a housing which encloses said stepper motor and part of said control lever, a further part of said control lever extending from said housing by way of an aperture (4) therein and this further part being provided with a portion (6) adapted for being conveniently engaged by a human operator.
Claim 4
Dependent Claim
38 words
A control device according to claim 2, wherein said portion of said control lever comprises a hand-grip portion and wherein there is mounted on said control lever, at least near said hand-grip portion, one or more control switches.
