The invention discloses a vehicle longitudinal control method which comprises the following steps: acquiring a vehicle real-time signal; longitudinal control planning is carried out according to the real-time signal and the emergency braking instruction; the longitudinal control planning result acts on the vehicle application layer, the vehicle application layer acts on the longitudinal brake deceleration control layer, the longitudinal brake deceleration control layer controls the deceleration execution driving layer, and finally the deceleration execution driving layer controls the vehicle chassis physical layer; wheel speed information and deceleration information in the action process of the vehicle chassis physical layer are fed back to the input and feedback signal processing layer; and longitudinal control planning adjustment is carried out according to the feedback information and the vehicle real-time signal. According to the scheme, when the emergency braking instruction is obtained, the longitudinal control plan is made in time, the braking requirement under the emergency condition is met, meanwhile, the multi-party data information of the vehicle is obtained, the condition of the vehicle is considered, and the safety of vehicle longitudinal control is ensured from the external aspect and the internal aspect.
本方案公开了一种车辆纵向控制方法,包括,获取车辆实时信号;根据实时信号和紧急制动指令进行纵向控制规划;纵向控制规划结果作用于车辆应用层,车辆应用层作用于纵向制动减速控制层,纵向制动减速控制层对减速执行驱动层进行控制,最后减速执行驱动层对车辆底盘物理层进行控制;车辆底盘物理层动作过程中的轮速信息、减速度信息反馈至输入与反馈信号处理层;根据反馈信息和车辆实时信号进行纵向控制规划调整。本方案在获取到紧急制动指令时即时做出纵向控制规划,满足紧急情况下的制动需求,同时获取车辆自身的多方数据信息,考虑自车车辆的情况,从外部和内部两个方面确保车辆纵向控制的安全性。
