Description

一种在智能驾驶车辆上实现无线充电功能的控制方法
技术领域
本发明属于无线充电技术领域，特别是涉及一种在智能驾驶车辆上实现无线充电功能的控制方法。
背景技术
当前智能驾驶车辆无线充电功能的实现控制策略主要为：1、智能驾驶车辆行驶进无线充电区域后，由智能驾驶系统判断车辆停止位置是否准确，并在满足条件时将无线充电控制指令通过总线发送给整车控制器VCU；VCU在收到无线充电控制指令后，判断车辆状态且无整车故障，满足无线充电条件后，确定允许启动无线充电功能，VCU通过硬线向无线充电模块WPT发送唤醒信号，WPT启动后进行自检并搜索地面发射端；WPT自检完成后，则通过硬线向VCU发送无线充电待机状态信号；WPT搜索到地面发射端并满足要求后，则通过硬线向VCU发送无线充电准备就绪信号；VCU在接收到WPT发送的无线充电待机状态信号和无线充电准备就绪信号这两个有效信号并综合判断车辆当前状态满足条件后，正式进入无线充电流程。
但是现有的智能驾驶车辆无线充电功能的实现控制策略存在下述缺点：1、由于在OFF挡状态下，整车上所有控制器和智能驾驶系统均处于休眠状态，现有技术必须确保钥匙始终处于ON挡，确保VCU一直处于激活状态并能正常接收相关控制指令或信号，因此现有技术无法在OFF挡下实现无线充电的功能，在功能实现上存在局限性；2、当智能驾驶系统出现故障，无法通过总线将无线充电控制指令发送给VCU时，即使进入到无线充电区域，也无法正常进行充电。
发明内容
为了克服上述问题，本发明提供了一种在智能驾驶车辆上实现无线充电功能的控制方法。
本发明所采用的技术方案是：
一种在智能驾驶车辆上实现无线充电功能的控制方法，包括以下步骤：
步骤一：在无线充电模块上配置自动感应模块，在进入到无线充电区域后，能自动搜索并识别地面发射端，从而激活WPT，此时WPT虽然被激活，但是不处于工作状态，也不往总线上发送任何报文，整车上控制器均处于休眠状态；
步骤二：WPT被激活后，通过硬线激活VCU，VCU被激活后完成初始化及自检；
步骤三：WPT通过各工作点效率判断无线充电模块的车载端和地面端位置是否对准，在确认满足条件且无故障后，通过硬线向VCU发送无线充电控制指令信号；
步骤四：VCU在接收到WPT发送的无线充电控制指令信号，并综合判断车辆当前状态满足条件后，正式启动进入无线充电流程；
步骤五：进入无线充电流程，VCU分别唤醒BMS、MCU、DCDC、WPT等整车上的控制器；
步骤六：其中WPT被VCU唤醒后，完成初始化及低压自检，正式进入工作状态，开始往总线上发送报文；
步骤七：VCU判断满足无线充电的条件，引导进入无线充电状态，从而实现无线充电功能。
可选的，在步骤一之前还包括：
WPT被激活后向智能驾驶系统处理器发送请求信号，如果智能驾驶系统处理器被占用，或发生故障，则通过硬线激活VCU，再顺序执行步骤一至步骤七；如果智能驾驶系统处理器处于空闲状态，则由智能驾驶系统处理器开启充电流程。
本发明的发明点包括：
1、无论钥匙状态处于ON挡还是OFF挡，智能驾驶车辆均能实现无线充电功能，不存在功能实现上的局限性；
2、在整个无线充电过程中，无需智能驾驶系统的参与，在进入到无线充电区域后，即使智能驾驶系统出现故障无法往总线上正常发送信号，也同样能实现无线充电功能。
附图说明
图1为本发明所述一种在智能驾驶车辆上实现无线充电功能的控制方法的流程图。
具体实施方式
下面对本发明作进一步的说明，但本发明并不局限于这些内容。
实施例
一种在智能驾驶车辆上实现无线充电功能的控制方法，包括以下步骤：在无线充电模块上配置自动感应模块，在进入到无线充电区域后，能自动搜索并识别地面发射端，从而激活WPT，此时WPT虽然被激活，但是不处于工作状态，也不往总线上发送任何报文，整车上控制器均处于休眠状态；WPT被激活后，通过硬线激活VCU，VCU被激活后完成初始化及自检；WPT通过各工作点效率判断无线充电模块的车载端和地面端位置是否对准，在确认满足条件且无故障后，通过硬线向VCU发送无线充电控制指令信号；VCU在接收到WPT发送的无线充电控制指令信号，并综合判断车辆当前状态满足条件后，正式启动进入无线充电流程；进入无线充电流程，VCU分别唤醒BMS、MCU、DCDC、WPT等整车上的控制器；其中WPT被VCU唤醒后，完成初始化及低压自检，正式进入工作状态，开始往总线上发送报文；VCU判断满足无线充电的条件，引导进入无线充电状态，从而实现无线充电功能。
可选的，在步骤一之前还包括：
WPT被激活后向智能驾驶系统处理器发送请求信号，如果智能驾驶系统处理器被占用，或发生故障，则通过硬线激活VCU，再顺序执行步骤一至步骤七；如果智能驾驶系统处理器处于空闲状态，则由智能驾驶系统处理器开启充电流程。这是本发明的创新点之一。
指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。
