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

A |     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。    Colombo, Oct 19 (UNI) President Ranil Wickremesinghe is as corrupt as any other politician and he cannot save Sri Lanka from the present economic crisis, the leader of the country's largest leftist group said in remarks published on Wednesday.
Anura Kumara Dissanayake of the Janatha Vimukti Peramuna (JVP) also said that the mass protests in Sri Lanka failed to achieve its aim of capturing power although it forced President Gotabaya Rajapaksa to flee "for want of proper leadership and planning", The Island newspaper reported.
Dissanayake has said ‘Aragalaya’, as the mass protests against Sri Lanka's unprecedented economic mess was known, failed "for want of proper leadership and planning though it compelled Gotabaya Rajapaksa to give up executive powers".
He pointed out in a television interview that although the Rajapaksas’ power collapsed, "they were able to quickly regain, and consolidate political power, by installing UNP leader Ranil Wickremesinghe to complete the remainder of Gotabaya Rajapaksa’s term".
The JVP leader added that the incumbent Wickremesinghe administration was as corrupt as successive Rajapaksa administrations.
He felt that having forced Gotabaya Rajapaksa to flee Sri Lanka, the protest should have been diverted towards Parliament and force the government to dissolve it and call for a fresh election.
Because of this failure, the Rajapaksas succeeded in regaining political power, he added.
Commenting on former Army chief and MP Sarath Fonseka’s assertion that the ongoing anti-government struggle may lead to another armed rebellion, the JVP leader emphasized that his party wouldn’t go on that path again.
The JVP launched insurgencies in 1971 and 1987-89, leaving thousands dead.
Asked to explain the JVP's strategy, Dissanayake said they believed that the government should be relentlessly pressed until it called a general election.
“We’ll secure power through elections,” he said, warning the electorate not to be deceived by the Rajapaksas and Wickremesinghe again.
Dissanayake alleged that the the leader of the main opposition Samagi Jana Balavegaya (SJB), Sajith Premadasa, "was also part of the utterly corrupt political party system that ruined the country".
"(Premadasa) as well as a vast majority of those around him cannot absolve themselves of waste, corruption, mismanagement and irregularities though they now pretended to be paragons of virtue," he added.
UNI MR。     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。

B |          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。

C | 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。

D |     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。

E | 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。
