Abstract
本发明涉及车辆技术领域，具体为一种基于车路协同预测的自动驻车预加载方法及相关设备，方法包括：构建前瞻路径模型以预测车辆前方一定范围内的停车场景；当预测到车辆到达停车场景时，导航模块向AVH控制器发送预激活触发信号，AVH控制器向EMB执行器发送预加载指令，驱动电机带动滚珠丝杠机构将制动间隙缩减，通过位置传感器闭环控制确保无异常摩擦，同时控制坡度传感器和车载称重系统计算维持驻车所需的基础驻车力并缓存；激活时调用缓存的基础驻车力，设定需求制动力为基础驻车力加安全冗余，引入分级参数矩阵，通过轮速传感器监测溜车趋势并触发追加驻车力；本发明能够提高驻车的稳定性和安全性。

The invention relates to the technical field of vehicles, in particular to an automatic parking preloading method based on cooperative prediction of a vehicle road and related equipment; when the vehicle is predicted to reach a parking scene, the navigation module sends a pre-activation trigger signal to the AVH controller, the AVH controller sends a pre-loading instruction to the EMB actuator, the driving motor drives the ball screw mechanism to reduce a braking gap, abnormal friction is avoided through closed loop control of the position sensor, meanwhile, the gradient sensor and the vehicle-mounted weighing system are controlled to calculate and maintain basic parking force required by parking, the basic parking force of the buffer is called during activation, required braking force is set as the basic parking force to add safety redundancy, a grading parameter matrix is introduced, the sliding trend is monitored through the wheel speed sensor, and additional parking force is triggered.
