The invention relates to the technical field of automobiles, in particular to a transverse control method and device, a vehicle, a medium and a product, and the method comprises the steps that vehicle body posture data, driver hand torque and front road condition image information of the vehicle are obtained; extracting a lane center line of a target lane in the front road condition image information; the offset distance between the vehicle body center line of the vehicle and the lane center line is calculated, and the target auxiliary torque needing to be provided by the electric power steering system is calculated according to the offset distance, the vehicle body posture data and the driver hand torque; and assisting the vehicle to perform transverse control based on the target auxiliary torque. Therefore, the problems that in the prior art, the target resultant moment required by lane keeping cannot be calculated generally, and the hand moment and the auxiliary moment of the driver cannot be reasonably distributed, so that the flexibility of lane keeping assistance and the safety of driving the vehicle by the driver are reduced, man-machine conflicts are increased, and the driving comfort of the driver is reduced are solved.
本申请涉及汽车技术领域,特别涉及一种横向控制方法、装置、车辆、介质及产品,其中,方法包括:获取车辆的车身姿态数据、驾驶员手力矩和前方路况图像信息;提取前方路况图像信息中目标车道的车道中心线;计算车辆的车身中心线与车道中心线的偏移距,根据偏移距、车身姿态数据和驾驶员手力矩计算电动助力转向系统需要提供的目标辅助力矩;基于目标辅助力矩辅助车辆进行横向控制。由此,解决了相关技术中通常无法计算出车道保持所需目标合力矩,并无法对驾驶员手力矩和辅助力矩进行合理分配,从而降低了车道保持辅助的灵活性和驾驶员驾驶车辆的安全性,增加了人机冲突,降低了驾驶员的驾驶舒适性等问题。
