The invention relates to the technical field of automobile parking, in particular to a DCT gearbox full-automatic parking control method and system and an automobile. The method includes: acquiring parking distance of a target vehicle, and calculating target vehicle speed according to the parking distance of the target vehicle; vehicle wheel end brake pressure and expected driving torque are calculated in real time according to the target vehicle speed; the vehicle wheel end brake pressure and the expected driving torque are received, the target driving torque is converted into the corresponding expected driving torque, and a clutch control strategy is adjusted according to the vehicle wheel end brake pressure; and the corresponding expected driving torque is received and responded, and the adjusted actual vehicle speed and the adjusted actual parking distance are output. According to the method, ESP and TCU control logics are resorted in the APA parking process, the TCU control method is adjusted, finally, the vehicle speed and the parking distance are accurate, and the APA parking process is comfortable and controllable.
本发明涉及汽车泊车技术领域,尤其是涉及一种DCT变速箱全自动泊车控制方法、系统及汽车。包括获取目标车辆的停车距离,根据目标车辆的停车距离计算目标车速;根据目标车速实时计算车辆轮端制动压力与期望驱动扭矩;接收车辆轮端制动压力与期望驱动扭矩,将目标驱动扭矩转换成对应的期望驱动扭矩,根据车辆轮端制动压力调整离合器控制策略;接收并响应对应的期望驱动扭矩,输出调整后的实际车速和实际停车距离。本发明主要为在APA泊车过程中对ESP,TCU控制逻辑重新梳理,调整TCU控制方法,最终实现车速,停车距离精准,APA泊车过程舒适可控。
