Abstract
Abstract A stable reference platform is securely anchored within the passenger compartment of a motor vehicle. The positioning and anchoring of the platform is accomplished without removing or engaging the passenger seat, and in a manner which avoids soiling and/or damage to the passenger compartment. The reference platform functions to support devices used to automatically operate the vehicle during testing thereof.

Claim 1
Independent Claim
111 words
A reference platform for lockably positioning and orienting control and/or measuring units within the passenger compartment of a motor vehicle comprising a support plate assembly releasably attached to a vehicle steering wheel at the lower apex thereof, spaced apart guideways connected to the support plate assembly on opposite sides of the lower apex of the steering wheel, a connecting plate movably connected to the support plate assembly, the connecting plate having rollers in engagement with the guideways, a control unit positioned within the passenger compartment, and a holding arm connected between the control unit and the connecting plate for manipulating the steering wheel in response to movements of the control unit.
Claim 2
Dependent Claim
111 words
A reference platform for lockably positioning and orienting control and/or measuring units within the passenger compartment of a motor vehicle comprising a support plate assembly releasably attached to a vehicle steering wheel at the lower apex thereof, spaced apart guideways connected to the support plate assembly on opposite sides of the lower apex of the steering wheel, a connecting plate movably connected to the support plate assembly, the connecting plate having rollers in engagement with the guideways, a control unit positioned within the passenger compartment, and a holding arm connected between the control unit and the connecting plate for manipulating the steering wheel in response to movements of the control unit.
Claim 3
Dependent Claim
68 words
A reference platform as in claim 1 wherein the support plate assembly includes portions positioned on the inside surface of a steering wheel rim, a clamping element having a portion thereof positioned on the outside surface of the rim, and means for urging together the clamping element and the assembly portions on the inside of the steering wheel rim to thereby releasably secure the assembly to the rim.
Claim 4
Dependent Claim
26 words
A reference platform as in claim 2 wherein the support plate assembly is symmetrically arranged on opposite sides of the lower apex of a steering wheel.
Claim 5
Dependent Claim

Claim 8
Dependent Claim
65 words
A reference platform as in claim 1 wherein the connecting plate includes a pair of guide arms each extending outwardly from the holding arm in opposite directions, and wherein the rollers include at least one roller connected to each guide arm cooperating with the spaced apart guideways of the support plate assembly, each of the guideways having a U-shaped configuration with the rollers positioned therein.
Claim 9
Dependent Claim
74 words
A reference platform as in claim 1 wherein the connecting plate includes a pair of guide arms each extending outwardly from the holding arm in opposite directions, and wherein the rollers include at least one roller connected to each guide arm cooperating with the spaced apart guideways of the support plate assembly, each of the guideways having a torus shape and the rollers each having a V-shaped circumferential groove that engages the torus guideways.
Claim 10
Dependent Claim
71 words
A reference platform as in claim 1 wherein the holding arm has a guide at the end thereof opposite the connecting plate, a cross beam slidably connected to the holding arm guide, and movable holders at the ends of the cross beam connected between the cross beam and the control unit whereby movements of the control unit are transmitted to the cross beam and holding arm guide via the movable holders.
