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: 5
Claim 1
Independent Claim 76 words
Control apparatus comprising a fixed support member, a movable member supported by the support member for movement with respect to the support member, electrical stepper motor means of which a stator part is connected to said support member and a mover part is connected to said movable member, and energisation supply means for controlling the energisation of the windings of said motor means to produce a controlled form of resistance to movement of said movable member.
Claim 2
Dependent Claim 76 words
Control apparatus comprising a fixed support member, a movable member supported by the support member for movement with respect to the support member, electrical stepper motor means of which a stator part is connected to said support member and a mover part is connected to said movable member, and energisation supply means for controlling the energisation of the windings of said motor means to produce a controlled form of resistance to movement of said movable member.
Claim 3
Dependent Claim 85 words
Control apparatus according to claim 1, in which the movable member is a movable control member, for example a motor vehicle accelerator or clutch pedal, or a manual control lever or the like on an aircraft, boat or the like, and wherein the control of said electrical motor is such as to produce one or more controllable detent positions in the movement of the member and/or a controllable overall resistance which may or may not be constant throughout the range of movement of the member.
Claim 4
Dependent Claim 30 words
Control apparatus according to claim 2, wherein the position of the or each detent and the extent and distribution of the resistance to movement is controlled according to external conditions.
Claim 5
Dependent Claim 100 words
Control apparatus according to claim 1, including a movable member which is movable to execute a control function and electrical stepper motor means including a mover part coupled to said movable member, the motor means being operable for driving the movable member in an automatic mode of the apparatus and/or for generating a general or localised resistance to such movement other than by the motor means, the electrical motor means being such that the force for said driving or said resistance generating is producible by the application of power to windings forming part of the stator part of the motor.
