The invention relates to the technical field of road model construction, particularly provides a vehicle and an automatic driving control method thereof, and aims to solve the problem that the current automatic driving perception precision is still insufficient to provide vehicle smoothness. An existing control strategy is limited by a fuzzy target, and hardware capabilities of a shock absorber and a spring cannot be fully used. In order to achieve the purpose, the control method comprises the steps that S1, a road bump feature model collected by a preceding vehicle and first driving data of the vehicle are obtained; s2, according to the road bumping feature model and the first driving data, determining a damping coefficient required for the vehicle to pass through the front bumping feature; and S3, when the vehicle passes through the front bumping feature, adjusting is conducted according to the damping coefficient needed by the front bumping feature. The damping coefficient can be matched with the jolting characteristic when the vehicle passes through the jolting characteristic, jolting of the vehicle is reduced, the vehicle can pass through a jolting road section more stably and safely, and the comfort level and safety of a user are guaranteed.
本发明涉及道路模型构建技术领域,具体提供一种车辆及其自动驾驶的控制方法,旨在解决当前的自动驾驶感知精度仍然不足以提供车辆平顺性的需要;现有控制策略受限于模糊的目标,不能充分使用减振器、弹簧的硬件能力的问题。为此目的,本发明的控制方法包括:S1、获取前序车辆采集到的道路颠簸特征模型和车辆的第一行驶数据;S2、根据道路颠簸特征模型和第一行驶数据确定车辆经过前方颠簸特征所需的阻尼系数;S3、在车辆经过前方颠簸特征时,按照前方颠簸特征所需的阻尼系数进行调节。可以使车辆经过颠簸特征时阻尼系数与之相匹配,减少车辆的颠簸,以使车辆能够更加平稳和安全地通过颠簸路段,保证用户的舒适度和安全性。
