Abstract: A lane centering fusion system including a primary controller determining whether a vehicle is centered within a lane of travel. The primary controller includes a primary lane fusion unit for fusing lane sensed data for identifying a lane center position. A secondary controller determines whether a vehicle is centered within a lane of travel. The secondary controller includes a secondary lane fusion unit for fusing lane sensed data for identifying the lane center position. The primary controller and secondary controller are asynchronous controllers. A lane centering control unit maintains the vehicle centered within the lane of travel. The lane centering control unit utilizes fusion data output from the primary controller for maintaining lane centering control. The lane centering control unit utilizes fusion data output from the secondary controller in response to a detection of a fault with respect to the primary controller.

Abstract translation: 一种车道对中融合系统，包括确定车辆是否位于行驶车道内的主控制器。 主控制器包括用于识别车道中心位置的用于对车道感测数据进行熔合的主车道融合单元。 二级控制器确定车辆是否居中在行驶车道内。 次级控制器包括用于对车道感测数据进行熔合以识别车道中心位置的次车道融合单元。 主控制器和二次控制器是异步控制器。 车道中心控制单元将车辆保持在行驶车道的内部。 车道对中控制单元利用从主控制器输出的融合数据来维持车道对中控制。 车道对中控制单元响应于相对于主控制器的故障的检测，利用从次级控制器输出的融合数据。
