Abstract:
In a power-assisted steering system or power steering system having an electric motor, which drives a worm gear mechanism that has a composite gear wheel in the form of a worm wheel, the worm wheel includes a ring gear connectible to a hub via a first disk, and an annular projection of the first disk axially engages with the ring gear.In order to improve the centering of the component parts of the composite gear wheel in the tangential direction, and in order to render the power transmission in the gear wheel uniform, the annular projection on the first disk is provided with one or more depressions in the axial direction to form tooth-like projections, which form a drive-type toothed section and engage with depressions on an axial side face of the ring gear.
Abstract:
A method for acquiring a position (1) of a motor vehicle (2) on a road (3), road geometric data (4) and travel data (5) being recorded. First position data (1) of the motor vehicle (2) relative to the road (3) is calculated from the recorded road geometric data (4) and travel data (5). Road course data (6) is calculated from the road geometric data (4) and the travel data (5), the second position data (7) of a following vehicle (21) which is following the vehicle (2), relative to the vehicle (2), is recorded, and third position data (8) of the following vehicle (21) relative to the road (3) is calculated from the road course data (6), the first position data (1) of the vehicle (2) and the second position data (7) of the following vehicle (2′).
Abstract:
A vehicle guidance system for assisting a driving lane change includes an object detection unit for detecting objects in a laterally adjacent rearward side space area of the vehicle. An analysis unit receives signals from the object detection unit and determines whether an object is situated in a dead angle section (blind spot) of the monitored rearward side space, or whether any such object in a section of the monitored rearward side space which is rearward beyond a dead angle section is moving forward at a higher speed than the system vehicle. If so, and if, in addition, it detects at the same time a lane change request pertaining to the corresponding side area, it activates a warning indicating unit for emitting a warning signal. According to the invention, a position detection device is provided which determines path data of the obstacle vehicle and the road geometry data, as well as the position of the system vehicle on the road. When the object detection unit detects an obstacle vehicle which is following in the rearward side space, corresponding to the covered distance recorded by the position detection device and the road geometry, a position assignment of the vehicle which is following is determined relative to the road.
Abstract:
Disclosed is a bearing system for a worm engaging with a worm wheel as part of a steering gear, wherein the bearing system comprises at least one bearing with an outer ring, an inner ring, and rolling bodies that are movably accommodated between the outer an inner rings, the bearing being pivotally arranged in a bearing seat for accommodating the outer ring of the bearing, and wherein the inner ring accommodates one of the two shaft ends of the worm in order to seat said shaft end of the worm radially in the housing of the steering gear. For an improved dampening of the worm at least one spring element, which exerts a spring force on a region of the outer ring of the bearing, is provided at the bearing, said spring force supporting a pivotal motion of the worm toward the worm wheel.

Abstract:
An electric power assisted steering system for motor vehicles having a worm gear mechanism is operatively connected to a drive shaft of an electric drive motor. A radial load is applied to the worm by a prestressing device, the prestressing device being configured as a hydraulic pressure device. It is possible to connect the drive shaft to the worm by a coupling, and the worm is mounted in this region by a pivotable bearing.
Abstract:
Method of assisting a motor vehicle in changing from a current lane to an adjacent target lane. The space in front and the space behind the vehicle at least in the adjacent target lane is monitored, the distance of objects (in particular vehicles) detected there, and their speeds are measured, and safety distances calculated therefrom. If all the measured distances are greater than the calculated safety distances, a possible lane change is signalled.
Abstract:
The invention relates to a lane device (30) and a method for detecting the lane of a vehicle (10), as well as to a selector device which interacts with the lane device (30). The lane device (30) contains evaluation means (32, 35, 37) for evaluating distance data (60, 61, 66) of at least one distance sensor (58, 59, 65), it being possible to determine a lateral distance (d1-d4) from a reference body (62, 64) which runs essentially continuously to the side of the lane, at least in sections, from the distance data (60, 61, 66). The evaluation means (32, 35, 37) are configured to acquire lane data (36) as a function of the distance data (60, 61, 66). According to the invention, the evaluation means (32, 35, 37) are configured to filter out interference information, caused in particular by vehicles (17) present in the region of the lane or discontinuities (63) of the reference body (62, 64), from the distance data (60, 61, 66).
