Embodiment Construction

[0029] As required, specific embodiments of the invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention that may be embodied in various and alternative forms. The figures are not necessarily to scale; some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present invention.

[0030] As an example, such as figure 1 As shown, the vehicle A symbolically marked at the starting position 1 is spaced from the target lane centerline 2 or deviates from the lateral deviation d y , the direction of travel 3 of the motor vehicle A surrounds the centerline 2 of the target lane at a deviation angle Ψ. lateral deviation d y and the deviation angle Ψ are determined by the positi...

Abstract

A lane-keeping method and system for a motor vehicle determines a transverse deviation and an misalignment angle of the motor vehicle relative to a target lane centerline, calculates a reference track for the motor vehicle to follow to return to the centerline using the transverse deviation and the misalignment angle, determines a reference yaw rate using a curvature of the reference track and a longitudinal speed of the vehicle, and compares the reference yaw rate with an actual yaw rate of the vehicle to determine a control deviation. A steering input is then applied to a steering system of the motor vehicle to minimize the control deviation.

Description

[0001] This application claims the benefit of foreign priority from DE 102012200009.7 filed January 2, 2012, which is hereby incorporated by reference in its entirety. technical field [0002] The invention relates to a method and a lane keeping assistance system for assisting a driver of a motor vehicle in keeping a lane. Background technique [0003] One of the main tasks when driving a motor vehicle is to set the steering angle to follow a desired driving route, which may be determined, for example, by lanes marked on a road. Deviating from the current lane due to driver inattention is a common cause of accidents. [0004] Therefore, in order to increase the active safety of motor vehicles, devices are proposed to notify inattentive drivers of accidental lane departures. However, greater improvements in safety can be achieved through devices in motor vehicles that automatically respond to the present dangerous situation. A condition for this is that the steering system ...
