比亚迪智能轮胎专利曝光：四轮可根据路况自动充放气 互不干扰_我的网站

一 |     8月26日消息，近期，国家知识产权局公示了比亚迪批量申报的多项轮胎相关发明专利，覆盖可变电控轮胎骨架、四轮独立充放气、轮胎内壁光栅传感、双层防爆多气腔等多个方向，整套技术方案形成完整自研体系。

But more restrictions on doing your business outdoors may be coming to the island nation soon.,Freedom Camping is camping on public land without paying a fee and is an activity quickly growing in popularity in New Zealand. In 2019, the year before the country shut down tourism due to the COVID-19 pandemic, more than 245,000 freedom campers enjoyed New Zealand’s famous landscapes while “freedom camping.” Of those, only 91,000 were Kiwis, indicating freedom camping is becoming a major tourist attraction for the small country.,However, it is also causing problems, something the Responsible Campers Association (RCA) wants to fix by adding more regulations on where freedom campers do their personal business and what they do with it after they are done.,'Crappiest Fountain Ever': UK Envoy's Husband Slashes Controversial New Zealand Landmark30 May, 10:23 GMT,The association wants new rules mandating that excrement must be buried at least 15cm (5.9 inches) and must be done at least 15 meters (49.2 feet) away from the nearest waterway.,The plea comes after multiple localities banned freedom campers from popular destinations because of a perceived increase in human waste and toilet paper being left at sites around the country. The issue became so heated that New Zealand’s tourism minister Stuart Nash told Radio New Zealand that freedom campers “pull over to the side of the road and … s*** in our waterways.”,The spokesperson for the RCA, Bob Osborne, says that blaming freedom campers is unfair. “There is no evidence linking any specific group to this undesirable practice which affects travelers all over New Zealand,” he said.,While the RCA advocates for a more permanent solution of more public restrooms, Osborne says that in the meantime, mitigation of the worst side effects of public defecation can be a solution, namely burying excrement and toilet paper and keeping it out of water sources. The association also stresses that campers should not be punished for the actions of a few bad apples, and that bad behavior should be punished, not camping itself.,Technically, public defecation is an offense in New Zealand that can result in a $200 fine, but that fine will be waived if the offender can show they had reason to believe no one could see them doing their business. Nash will be introducing new regulations to parliament later this year, including harsher fines for bad behavior and restrictions on where freedom campers can park.,With COVID-19 restrictions on tourism being lifted in the country, 2022 is expected to be a big year for freedom camping in New Zealand. With unburied defecation still allowed under law, campers are advised to watch where they step.。     这套方案中，轮胎内壁光栅传感专利通过轮胎内壁全覆盖式柔性光栅贴片，消除传统胎压监测的形变盲区，同步采集胎压、温度、轮胎形变等多维状态数据，为胎压调节提供感知输入。         与之配套的是主动四轮独立充放气系统专利。简单来说，这套系统可实现无需下车，车辆对每个轮胎单独完成充气、放气，四轮可同步操作，互不干扰。     过往主动充放气技术多应用在军用越野轮式装甲车，大多采用车桥控制模式，前桥两轮、后桥两轮统一调压，或是管路共用，轮胎只能够依次调压。    路虎早期中央充放气专利同样以桥控为主，无法做到每个车轮充放气通道完全独立并行，大多只能整车统一升压降压，单轮独立调节能力有限。          比亚迪这套充放气系统主要由充气阀组、放气阀组两部分构成。

三 | 充气阀组接入车载气源，分出多路出气口分别对接4条轮胎，每一路管路都配有独立电磁阀，可单独控制对应轮胎充气。    放气阀组为每条轮胎配备独立放气电磁阀，排气口直连外界大气，需要给某一轮胎降压时，仅开启对应阀门即可向外排气。每条轮胎充、放气通路均可单独通断，支持多轮同步充放气，调节效率大幅提升。     两套专利相互配合，车辆依靠光栅贴片识别路面带来的轮胎状态变化，充放气系统据此动态调整各个车轮胎压。沙地、泥地越野场景下，系统可以降低胎压扩大轮胎接地面积。    行驶至铺装路面，自动将胎压恢复至标准数值；遇到轮胎慢撒气故障，也能够自动补压，不必立刻靠边停车，全程无需人工干预，优化轮胎抓地性能。
