Patent number: 9925988Abstract: A control system for a vehicle includes a computer. The computer is programmed to command application of one of up to a predetermined steering torque value and up to a predetermined net asymmetric braking force value. Each predetermined force is selected to achieve a predetermined vehicle yaw torque that is at most the lesser of a first maximum yaw torque resulting from actuating a steering system and a second maximum yaw torque resulting from actuating a brake system.Type: GrantFiled: February 24, 2017Date of Patent: March 27, 2018Assignee: FLORD GLOBAL TECHNOLOGIES, LLCInventors: Timothy D.

Patent number: 9139203Abstract: A lane tracking system for tracking the position of a vehicle within a lane includes a camera configured to provide a video feed representative of a field of view and a video processor configured to receive the video feed from the camera and to generate latent video-based position data indicative of the position of the vehicle within the lane. The system further includes a vehicle motion sensor configured to generate vehicle motion data indicative of the motion of the vehicle, and a lane tracking processor. The lane tracking processor is configured to receive the video-based position data, updated at a first frequency; receive the sensed vehicle motion data, updated at a second frequency; estimate the position of the vehicle within the lane from the sensed vehicle motion data; and fuse the video-based position data with the estimate of the vehicle position within the lane using a Kalman filter.Type: GrantFiled: November 4, 2011Date of Patent: September 22, 2015Assignee: GM Global Technology Operations LLCInventors: Nikolai K. Moshchuk, Shuqing Zeng, Xingping Chen, Bakhtiar Brian Litkouhi

Patent number: 8706417Abstract: A method for selecting an anchor lane for tracking in a vehicle lane tracking system. Digital map data and leading vehicle trajectory data are used to predict lane information ahead of a vehicle. Left and right lane boundary markers are also detected, where available, using a vision system. The lane marker data from the vision system is combined with the lane information from the digital map data and the leading vehicle trajectory data in a lane curvature fusion calculation. The left and right lane marker data from the vision system are also evaluated for conditions such as parallelism and sudden jumps in offsets, while considering the presence of entrance or exit lanes as indicated by the map data. An anchor lane for tracking is selected based on the evaluation of the vision system data, using either the fused curvature calculation or the digital map and leading vehicle trajectory data.Type: GrantFiled: July 30, 2012Date of Patent: April 22, 2014Assignee: GM Global Technology Operations LLCInventors: Shuqing Zeng, Bakhtiar Brian Litkouhi, Xingping Chen, James N.
