The invention discloses a diesel commercial vehicle full-automatic parking longitudinal control method and system, and the method comprises the steps that an APA actively judges whether a parking instruction issued by a vehicle owner is received or not every first preset time, and if the parking instruction is received, the APA obtains a target distance and a target speed according to the parking instruction, and sends the target distance and the target speed to an ESP; after receiving, the ESP judges the environment information of the target vehicle, and selects a parking mode according to the environment information; if the mode is the flat mode, the ESP performs parking operation according to the target distance and the target speed, and if the mode is the special mode, the ESP judges whether the current torque of the target vehicle meets the parking requirement or not; and if the parking requirement is not met, a request torque signal is sent to the EMS, and the EMS responds to the request torque signal so that the speed of the target vehicle can reach the target speed and controls the target vehicle to run at the target speed by the target distance. The problem that parking is difficult due to the fact that the diesel commercial vehicle is large in size is solved, and a vehicle owner can be helped to complete safe and reliable parking operation.
本发明公开了一种柴油商用车全自动泊车纵向控制方法及系统,该方法包括:每隔第一预设时间APA主动判断是否接收到车主下发的泊车指令,若接收到泊车指令,APA根据泊车指令得到目标距离和目标速度,向ESP发送目标距离和目标速度;ESP接收后判断目标车辆所处的环境信息,根据环境信息选择泊车模式;若为平坦模式,ESP根据目标距离和目标速度进行泊车操作,若为特殊模式,ESP判断目标车辆当前的扭矩是否满足泊车需求;若不满足泊车需求,向EMS发送请求扭矩信号,EMS响应请求扭矩信号,以使目标车辆的速度达到目标速度,并控制目标车辆以目标速度行驶目标距离。本发明解决了柴油商用车车型较大而导致泊车困难的问题,能够帮助车主完成安全可靠的泊车操作。
