Abstract: A lane keeping system for a vehicle sets a safe zone in which the driver can drive the vehicle. If the system determines that the driver is at risk of leaving the safe zone, the system takes a corrective action, such as notifying the driver or applying a steering correction to the vehicle. The system adjusts the width of the safe zone depending on the driver's capability to stay within the safe zone. A lane centering system may be capable of autonomously steering the vehicle to remain within a lane. The lane centering system may include a controller that determines a target path for the vehicle depending on certain parameters. The controller may model each of the lane delimiters in a simplified form. This facilitates the determination of one of the target paths (the centerline of the lane). The simplified form may be a 3rd order polynomial equation.

Abstract translation: 用于车辆的车道保持系统设置驾驶员驾驶车辆的安全区域。 如果系统确定驾驶员有离开安全区域的风险，则系统采取纠正措施，例如通知驾驶员或向车辆应用转向校正。 系统根据驾驶员停留在安全区域的能力来调整安全区域的宽度。 车道定心系统可能能够自主地转向车辆以保持在车道内。 车道对中系统可以包括根据某些参数来确定车辆的目标路径的控制器。 控制器可以以简化的形式对每个通道分隔符进行建模。 这有助于确定目标路径之一（车道的中心线）。 简化形式可以是三阶多项式方程。
