In-vehicle devices, systems, and methods for vehicle driving assistance are provided. The vehicle-mounted equipment is configured to judge whether the risk can be avoided if the vehicle is controlled by a steering upper limit set by a vehicle system when determining that the vehicle has the risk of crossing a lane boundary which is forbidden to cross based on sensor data and/or map data, the upper steering limit comprises a parameter for constraining lateral movement of the vehicle in association with the vehicle speed; and when it is judged that the risk cannot be avoided, an adjustment value of the steering upper limit is calculated based on the current vehicle state and the curvature radius of the current driving lane, and an electronic steering system of the vehicle is controlled to control transverse movement of the vehicle according to the adjustment value, so that the risk is avoided.

    提供了用于车辆驾驶辅助的车载设备、系统和方法。所述车载设备被配置成:在基于传感器数据和/或地图数据确定出车辆存在跨越禁止跨越的车道边界的风险时,判断如果以车辆系统设定的转向上限操控车辆,所述风险是否能够被规避,其中,所述转向上限包括用于与车速相关联地约束车辆横向运动的参数;并且在判定为所述风险无法被规避时,基于当前车辆状态和当前行驶车道的曲率半径计算所述转向上限的调整值,并控制车辆的电子转向系统以所述调整值操控车辆的横向运动,从而规避所述风险。
