Benefits of technology

The present invention is a system that adjusts the steering of a vehicle to prevent rollover. It uses unidirectional brakes to restrict the movement of the steering wheel at certain speeds and angles. The system also includes sensors to detect the position of the steering wheel and speed data. The technical effect of this invention is to prevent vehicles from rolling over, which can reduce accidents and damage to property.

Problems solved by technology

However, when a vehicle in which the ASRLD is installed is moving at no less than a predetermined rate of speed and the vehicle steering wheel is turned to no less than a predetermined left hand angle, the LHUBA is automatically applied, and the vehicle steering left hand range of motion is restricted such that the steering wheel may not be turned beyond the threshold of left hand rollover for the particular vehicle for the given vehicle speed.
Further, when a vehicle in which the ASRLD is installed is moving at no less than a predetermined rate of speed and the vehicle steering wheel is turned to no less than a predetermined right hand angle, the RHUBA is automatically applied, and the vehicle steering right hand range of motion is restricted such that the steering wheel may not be turned beyond the threshold of right hand rollover for the particular vehicle for the given vehicle speed.

first embodiment

[0024]Referring now to FIGS. 1 through 4 of the drawings, the invention is an adaptive steering range limiting device (ASRLD) 10 comprising a steering wheel 20, a steering column 30, a steering column position detection disc (SCPDD) 40, a pair of opposing unidirectional brake assemblies 50, an electronic control unit 80 and a sensor 85. Furthermore arrow 92 defines a left hand or counterclockwise (CCW) direction indication arrow and arrow 94 defines a right hand or clockwise (CW) direction indication arrow. Steering wheel 20 defines a conventional steering wheel as may commonly be found in a commercially available passenger vehicle. Steering column 30 defines a conventional steering column that serves to transmit steering torque from steering wheel 20 to a rack and pinion or other such vehicle wheel control device. SCPDD 40 defines a substantially thin preferably aluminum cylinder shaped disc 42 having a plurality of magnetic targets 44 embedded within disc 42 and spaced substantial...

fourth embodiment

[0030]Referring now to FIGS. 5 through 7 of the drawings, the invention is an adaptive steering range limiting device (ASRLD) 110 comprising a steering wheel 120, a steering column 130, a steering column disc device (SCDD) 140, an electronic control unit 180 and a block 185. Furthermore arrow 192 defines a left hand or counterclockwise (CCW) direction indication arrow and arrow 194 defines a right hand or clockwise (CW) direction indication arrow. Steering wheel 120 defines a conventional steering wheel as may commonly be found in a commercially available passenger vehicle. Steering column 130 defines a conventional steering column that serves to transmit steering torque from steering wheel 120 to a rack and pinion or other such vehicle wheel control device. SCDD 140 defines a substantially thin preferably aluminum cylinder shaped disc 142 having a plurality of actuator pins 144 affixed to disc 142 and spaced substantially equally about the periphery of disc 142. Actuator pins 144 a...

Abstract

The rollover prevention apparatus defines an adaptive steering range limiting device comprising a control unit and a pair of opposing unidirectional brake assemblies mounted to a steering column position detection disc. The rollover prevention apparatus prevents the steering wheel of the vehicle from being turned beyond the threshold of vehicle rollover, but otherwise does not restrict the rotational range of motion of the steering wheel of a vehicle.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This nonprovisional utility patent application is a continuation-in-part of and claims the benefit under 35 USC §120 to co-pending U.S. application Ser. No. 13 / 222,157 filed Aug. 31, 2011, which claims the benefit under 35 USC §119(e) of U.S. provisional application No. 61 / 378,482 filed Aug. 31, 2010 and of U.S. provisional application No. 61 / 385,535 filed Sep. 22, 2010, all of which are incorporated herein in their entirety by this reference.FIELD OF THE INVENTION[0002]The present invention relates to steering control devices and more especially devices for use in preventing steering to the point of vehicle rollover.BACKGROUND OF THE INVENTION[0003]Vehicle rollover—generally defined as vehicular accident in which a vehicle turns over on its side or roof—is an extremely dangerous form of a vehicle crash. Vehicle rollover accidents while relatively rare—estimated at approximately 3% of all vehicle crashes—account for a disproportionately h...
