The invention relates to a longitudinal control method and device of a vehicle, the vehicle and a storage medium, and the method comprises the steps that the target deceleration of the vehicle is determined based on the current pedal opening degree of the vehicle, and corresponding brake pressure is obtained in combination with the target deceleration and the iterative learning result of the last round; collecting the actual deceleration of the vehicle under the brake pressure, judging whether the vehicle meets a preset iteration stop condition or not, if the vehicle does not meet the preset iteration stop condition, carrying out the iteration learning of the round to obtain the iteration learning result of the round until the vehicle meets the preset iteration stop condition, and stopping the iteration learning of the round until the vehicle meets the preset iteration stop condition. And longitudinal control of the vehicle is carried out by using the iteration learning result of the corresponding round meeting the preset iteration stopping condition. Therefore, the technical problems that the real-time requirement of vehicle intelligent driving is difficult to meet, the engineering practicability is poor, and the safe driving requirement of vehicle intelligent driving cannot be met in the related technology are solved.
本申请涉及一种车辆的纵向控制方法、装置、车辆及存储介质,其中,方法包括:基于车辆的当前踏板开度确定车辆的目标减速度,并结合目标减速度和上一轮次的迭代学习结果,得到相应的制动压力;采集在制动压力下的车辆的实际减速度,判断车辆是否满足预设迭代停止条件,如果不满足预设迭代停止条件,则进行本轮次的迭代学习,得到本轮次的迭代学习结果,直至车辆满足预设迭代停止条件,并利用满足预设迭代停止条件对应轮次的迭代学习结果进行车辆的纵向控制。由此,解决了相关技术中,难以满足车辆智能驾驶的实时性要求,工程实用性不佳,且无法满足车辆智能驾驶安全行驶需求的技术问题。
