摘要： A method performed by a boundary estimation system for estimating a boundary of a road on which a vehicle is positioned and which comprises at least a first lane marking. The system monitors surroundings of the vehicle, detects one or more positions of the at least first lane marking, and approximates a geometrical representation of the at least first lane marking based on one or more of the detected positions of the at least first lane marking. The system further detects one or more positions of a road boundary of the road, approximates a relative lateral offset between the geometrical representation of the at least first lane marking and the detected road boundary, and defines a fictive outer boundary of at least a section of the road based on laterally shifting at least a section of the geometrical representation of the at least first lane marking the relative lateral offset.

摘要： Disclosed is an arrangement and a method for mitigating a forward collision between a host vehicle, having sensors for monitoring a road ahead and wheel brakes, and an oncoming vehicle. The sensors are utilized to estimate parameters of an oncoming vehicle. The estimated parameters are utilized to predict a future path of the oncoming vehicle, and host vehicle parameters are utilized to predict a future path of the host vehicle. The predicted future paths are assessed to determine if a forward collision is likely unavoidable assuming full freedom for performing avoidance maneuvers for both vehicles. The wheel brakes are controlled to reduce a relative longitudinal velocity between the vehicles at a predicted collision instant if determined that a forward collision is likely unavoidable at a determined relative longitudinal velocity above a first threshold.

摘要： A method is provided for intelligent scaling of torque overlay intervention for a semi-autonomous steering system in a road vehicle having a semi-autonomous steering function arranged to selectively apply a steering wheel overlay torque. If decided that a driver is significantly overriding an intervention, the overlay torque is scaled by a scaling factor being a function of applied steering wheel torque. If decided that the driver has been significantly overriding the intervention for more than a pre-determined first time period, the scaling factor is set to its lowest possible value for a specific driving situation. If decided that the driver has been significantly overriding the intervention for more than a pre-determined second time period, where the pre-determined second time period is equal to or exceeds the pre-determined first time period, the scaling factor is faded-out.
摘要翻译：提供了一种用于在具有半自主转向功能的道路车辆中的半自主转向系统的扭矩叠加干预的智能缩放的方法，其布置成选择性地施加方向盘重叠扭矩。如果决定驱动程序明显覆盖干预，则覆盖扭矩通过作为所应用的方向盘扭矩的函数的比例因子来缩放。如果决定驱动程序已经将干预显着地超过预定的第一时间段，那么缩放因子被设置为特定驾驶状况的最低可能值。如果决定驾驶员在预定的第二时间周期等于或超过预定的第一时间段的情况下，大大超过干预超过预定的第二时间段，则缩放因子被淡出。
