The invention relates to a vehicle longitudinal control method, device and equipment and a readable storage medium, and relates to the technical field of vehicle longitudinal control, and the method comprises the steps that drive-by-wire request targets are obtained, and the drive-by-wire request targets comprise a vehicle speed request target and a distance request target; when it is detected that the drive-by-wire request target is a vehicle speed request target, the target vehicle speed corresponding to the vehicle speed request target is converted into a target rotating speed according to response characteristics of a motor, and a driving system and a braking system are controlled based on the target rotating speed; when it is detected that the drive-by-wire request target is a distance request target, a first vehicle speed is planned according to the vehicle dynamic characteristics and the target distance corresponding to the distance request target, the first vehicle speed is converted into a target rotating speed according to the response characteristics of a motor, and a driving system and a braking system are controlled based on the target rotating speed to achieve longitudinal control over the vehicle. According to the method, the full-speed-section speed control requirement, the distance control requirement and the active deceleration control scene when the target vehicle speed is reduced can be met, and the longitudinal control precision can be effectively improved.

    本申请涉及一种车辆纵向控制方法、装置、设备及可读存储介质,涉及车辆纵向控制技术领域,包括获取线控请求目标,线控请求目标包括车速请求目标和距离请求目标;当检测到线控请求目标为车速请求目标时,根据电机的响应特性将车速请求目标对应的目标车速转化为目标转速,并基于目标转速控制驱动系统和制动系统;当检测到线控请求目标为距离请求目标时,根据车辆动力学特性和距离请求目标对应的目标距离规划出第一车速,并根据电机的响应特性将第一车速转化为目标转速,基于目标转速控制驱动系统和制动系统,实现车辆的纵向控制。本申请可满足全速段速度控制需求、距离控制需求以及目标车速降低时的主动减速控制场景,并可有效提高纵向控制精度。
