Abstract:
A vehicle steering system, with multiple independent systems, employing different route referencing, such as a primary system (10), referring to a physical reference line (30), or multiple discrete markers; and a secondary system (20), referring to an independent reference store (18), expressed as a sequential instruction table, configured as an emergency backup, implemented upon failure of the primary system; the system allows co-ordinated vehicle steering and braking, for adherence to a prescribe route; multiple discrete route markers (66) allow route banding (62), and multiple routes (60A, 60B).
Abstract:
A near object detection (NOD) system includes a plurality of sensors, each of the sensors for providing detection coverage in a predetermined coverage zone. Each of the sensors includes a transmit antenna for transmitting a first RF signal, a receive antenna for receiving a second RF signal and a means for sharing the target data between each of the plurality of sensors in the NOD system.
Abstract:
A image sequence is inputted (200) from the camera and vertical motion is estimated (202). A windowed horizontal edge projection (204) is extracted from the inputted image sequence (200) and the horizontal edges are projected (206). The horizontal edge projection (206) and the vertical motion estimation (202) are combined in a horizontal segmentation and tracking element (208), and forwarded to an object parameter estimation element (210) where the object's distance and height are estimated. This data is combined in a fusion with radar detection element (212). By correctly matching the overhead objects sensed by the radar and video camera, the proximity and relative speed can be ascertained. Once overhead objects have been identified they can be isolated and not considered for collision avoidance purposes.

Abstract:
A video amplifier for a radar receiver includes a temperature compensating attenuator. The attenuator includes a temperature sensitive device, such as a thermistor, arranged in a voltage divider network and is coupled in cascade between two filter stages. Each of the filter stages has a bandpass characteristic in order to filter low-frequency leakage signals and provide sensitivity control based on frequency and thus range, while also filtering high frequency signals to reduce aliasing.
Abstract:
A method for lane-keeping control of a lane-keeping support system provides a current command indicative of steering torque assist needed to steer a vehicle in following a target line between lane markings on a roadway during driving in lane-keeping control (LKC) mode. A map has two sets of limit data against a range of values of lateral acceleration to which the vehicle is subject, between which sets of limit data there is a range of values of the command during various phases of steering the vehicle to turn in the LKC mode. In order to compensate for undesired effect caused by any deviation of the range of values of the current command due to the presence of continuous disturbance, the two sets of limit data are corrected. To determine driver steering intervention, the instantaneous value of the current command is compared to two limit values established out of the corrected two sets of limit data.
Abstract:
The invention relates to a method of guiding a track-guided vehicle, according to which at least one wheel (11) of the vehicle is automatically guided along a track which acts indirectly on said wheel (11). According to the invention the wheel (11) is guided with an offset (25, 26) next to the track and perpendicular to the direction of travel of same, which reduces wear of the runway (12).
Abstract:
The invention relates to a driver assistance system of a motor vehicle and to a method for operating a drive assistance system of a motor vehicle. The invention comprises a detection means (24, 28, 30) for predetermined, instantaneous environmental parameters of a momentary traffic situation, a comparing means (28; 34) for comparing the detected instantaneous environmental parameters with stored environmental parameters which are acceptable for the driver assistance system. The inventive system also comprises an activating/deactivating means (28) for deactivating the drive assistance system if predetermined, instantaneous environmental parameters are located outside the environmental parameters which are acceptable for the driver assistance system, or the driver assistance system is activated if predetermined, instantaneous environmental parameters are located within the environmental parameters which are acceptable for the driver assistance system.
Abstract:
Systems and methods use cameras to provide autonomous navigation features. In one implementation, a driver assist navigation system is provided for a primary vehicle. The system may include at least one image capture device configured to acquire a plurality of images of an area in a vicinity of the primary vehicle; a data interface; and at least one processing device. The at least one processing device may be configured to: locate in the plurality of images a leading vehicle; determine, based on the plurality of images, at least one action taken by the leading vehicle; and cause the primary vehicle to mimic the at least one action of the leading vehicle.
Abstract:
Aspects of the present disclosure relate generally to identifying and displaying traffic lanes that are available for autonomous driving. This information may be displayed to a driver of a vehicle (101) having an autonomous driving mode, in order to inform the driver of where he or she can use the autonomous driving mode. In one example, the display (152, 810, 820) may visually distinguish between lanes that are available for auto-drive from those that are not. The display (152, 810, 820) may also include an indicator (850) of the position of a lane (836) (autodrive or not) currently occupied by the vehicle. In addition, if that lane is an autodrive lane the display (1010) may include information (1060) indicating how much further the vehicle may continue in the autonomous driving mode in that particular lane.
