The invention relates to the field of engineering transport vehicle automatic driving, and discloses a vehicle-road cooperation automatic driving layered correction control method and system, and the method comprises the following steps: constructing a recognition model based on a BP neural network in a roadside computing device; the vehicle response serves as input of a recognition model, and the recognition model transmits the driving gradient and the whole vehicle mass to the vehicle-mounted computing platform as output; when the vehicle is identified to be in the slope-free working condition, the vehicle shifts according to a normal gear shifting rule; and when the vehicle is identified to be in the ramp working condition, adopting a ramp gear shifting control strategy: carrying out grade division on different whole vehicle masses and driving gradients in advance, formulating ramp gear shifting control strategies under different grades, and determining the ramp gear shifting control strategy according to the received whole vehicle masses and driving gradients by a vehicle-mounted computing platform. Matching the corresponding grade and the ramp shift control strategy corresponding to the corresponding grade; and the ramp shifting strategy of the vehicle is corrected through the cooperative relationship between the roadside computing equipment and the vehicle-mounted computing platform.

    本发明涉及工程运输车自动驾驶领域,公开了一种车路协同自动驾驶分层修正控制方法和系统,控制方法包括以下步骤:在路侧计算设备中构建基于BP神经网络的识别模型;将车辆响应作为识别模型的输入,识别模型将行驶坡度和整车质量作为输出传递至车载计算平台;当辨识出车辆处于无坡度工况时,车辆按照正常换挡规律换挡;当辨识出车辆处于坡道工况时,采用坡道换挡控制策略:预先对不同的整车质量与行驶坡度进行等级划分,并制定不同等级下的坡道换挡控制策略,车载计算平台根据所接收到的整车质量、行驶坡度,匹配相应的等级以及相应等级对应的坡道换挡控制策略;通过路侧计算设备与车载计算平台的协同关系,对车辆的坡道换挡策略进行修正。
