Description
本发明属于车载设备领域，尤其是涉及 一种汽车降温的方法以及温度调节系统 。
夏天将汽车停在室内外一段时间后，汽车内温度将在短时间内升高，尤其是在室外暴晒的汽车，由于车内为封闭的环境、加上汽车材质普遍吸热的特性，车内温度很可能在不需多久就升到了50℃以上，当车主再回到车上时，温度将高得让人无法忍受。
很多上班族车主，他们平时上班呆在室内，温度仅仅20℃左右，而下班坐进私家车，却遭遇近50℃的高温桑拿，巨大的落差让人难以适应，但上车再开空调得等待几分钟的方可降温，这时间段内车主的衣服可能都已汗湿，所以此举并非最佳的解决方案。
如果汽车内的配备通信装置并能够接收到用户的手机位置信息，当车主的位置信息表现出持续向汽车移动的状态，汽车提前开启空调，当车主返回到汽车时，温度已经降低，适宜直接上车驾驶。
综上，针对于夏天停车车内温度快速升高、车主再返回汽车后高温难耐的缺陷，需要提供一种根据车主手机定位信息提前降低车内温度的方法。
本发明实施例提供了一种汽车降温的方法 ， 目的在于
针对夏天停车车内温度快速升高、车主再返回汽车后高温难耐的缺陷，提供一种根据车主手机定位信息提前降低车内温度的方法。

记录用户的手机定位信息接收端口以及用户返车判断方法，记录温度调节模式；
读取所述信息接收端口的信息，判断用户是否正在返回汽车；
若否，保持原样；
若是，探测当前车内温度数值，判断所述温度是否高于 20 度；
若否，保持原样；
若是，根据温度情况设定车载空调的降温模式，并开启空调。
本发明实施例还提供了一种温度调节系统，包括：
记录单元，返车判断单元，温度判断单元，降温单元，其中：
记录单元，用于记录用户的手机定位信息接收端口以及用户返车判断方法，记录温度调节模式；
返车判断单元，其输入端与所述记录单元的输出端连接，用于读取所述信息接收端口的信息，判断用户是否正在返回汽车；

降温单元，其输入端分别与所述记录单元的输出端以及所述温度判断单元的输出端连接，用于根据温度情况设定车载空调的降温模式，并开启空调。
该发明通过接收手机定位信息、掌握用户是否在返回汽车过程中，如果判断出用户正在返回汽车，则根据车内温度调整车载空调的降温模式并提前开启空调，实现了适时的、主动调节车内温度，避免了用户返回车后温度过高。

在步骤 S101 中记录用户的手机定位信息接收端口以及用户返车判断方法，记录温度调节模式。
在本实施例中，以用户 A 的汽车温度调节系统为例，记录用户的手机定位信息接收端口为接收用户 A
手机，通过该端口返回用户手机定位模块返回的位置信息，通过车内通信芯片（可以通过普通 SIM
卡与无线移动网络连接）接收该位置信息；记录用户返车判断方法，该模式为通过上述位置信息，判断用户是否以步行速度靠近汽车，并且用户与汽车直线距离小于 1000
米时，确定用户正在返回起床呢；另外记录温度调节模式，该模式与车内温度挂钩，如车内温度为 20-30 度对应的温度调节模式为自然模式，车内温度为 31-40
度对应为普通降温模式，车内温度为 40 度以上对应为快速降温模式，不同的温度调节模式对应汽车空调不同的出风速度和目标温度。
车内通信芯片接收手机的定位信息，温度调节模式与车内温度挂钩， 20-30 度为自然模式， 30-40 度为普通降温模式， 40
度以上为快速降温模式，用户返车判断模式为用户以一定步行速度靠近车子，并且靠近车子距离小于 1000m
时，确定用户在返车车内通信芯片接收手机的定位信息，温度调节模式与车内温度挂钩， 20-30 度为自然模式， 30-40 度为普通降温模式， 40
度以上为快速降温模式，用户返车判断模式为用户以一定步行速度靠近车子，并且靠近车子距离小于 1000m 时，确定用户在返车
在步骤 S102 中，读取所述信息接收端口的信息，判断用户是否正在返回汽车。
根据现有技术，通过车内通信芯片（可以通过普通 SIM
卡与无线移动网络连接）便可接收手机返回的位置信息，通过读取该信息便可以判断用户是否在正在返回汽车。
在步骤 S103 中，若用户未正在返回汽车，保持原样。
若用户 A 未正在返回汽车，保持原样。
在步骤 S104 中，若用户正在返回汽车，探测当前车内温度数值，判断所述温度是否高于 20
度。
若用户正在返回汽车，需探测当前车内温度数值，判断所述温度是否高于 20
度，以便于确定是否需要调节车内温度。
在步骤 S105 中，若判断出车内温度不高于 20 度，保持原样。
若判断出车内温度不高于 20 度，不需要调节车内温度，保持原样。
在步骤 S106 中，若判断出车内温度高于 20
度，根据温度情况设定车载空调的降温模式，并开启空调。
若判断出车内温度高于 20 度，根据温度情况设定车载空调的降温模式，并开启空调。若该温度为 35
度，可以得出对应的温度调解模式为普通降温模式，按记录设置相应的风速和目标温度，开启空调，当用户 A 返回到汽车的时候，车内温度已经调节到适宜的温度。
该发明通过接收手机定位信息、掌握用户是否在返回汽车过程中，如果判断出用户正在返回汽车，则根据车内温度调整车载空调的降温模式并提前开启空调，实现了适时的、主动调节车内温度，避免了用户返回车后温度过高。
