The invention relates to the technical field of intelligent driving, in particular to a vehicle longitudinal motion control method and device.The method comprises the steps that under the condition that it is detected that a vehicle enters a longitudinal motion control working condition, an expected driving route of the vehicle is obtained so as to confirm at least one power comfort index parameter of the vehicle at the current moment, and based on a performance index function of a preset single neural network, a target speed variable quantity is obtained through the at least one power comfort index parameter, the expected speed longitudinal speed of the vehicle is generated according to the target speed variable quantity, and the expected speed longitudinal speed is used for controlling the vehicle to move longitudinally. According to the embodiment of the invention, the expected speed at the ideal position can be output by the single neuron network based on the power comfort index parameter of the vehicle and the vehicle riding comfort evaluation index function, so that the dependence of longitudinal control on a vehicle dynamics model is reduced; the robustness and the self-adaptability of the vehicle longitudinal speed motion control system are improved, and the control system is more accurate.

    本申请涉及智能驾驶技术领域,特别涉及一种车辆的纵向运动控制方法及装置,其中,方法包括:在检测到车辆进入纵向运动控制工况的情况下,获取车辆的期望行驶路线,以确认车辆在当前时刻的至少一个动力舒适性指标参数,基于预设单神经元网络的性能指标函数,由至少一个动力舒适性指标参数得到目标速度变化量,并根据目标速度变化量生成车辆的期望速纵向速度,利用期望速纵向速度控制车辆进行纵向运动。本申请实施例可以基于根据车辆的动力舒适性指标参数和车辆乘坐舒适性评价指标函数,由单神经元网络输出理想位置下的期望速度,从而减少了纵向控制对车辆动力学模型的依赖,提高了车辆纵向速度运动控制系统的鲁棒性和自适应性,更加准确。
