【摘要】：汽車防撞預(yù)警裝置能夠在駕駛員行車安全距離控制不當(dāng)時(shí)通過(guò)語(yǔ)音設(shè)備發(fā)出警示信號(hào)，使駕駛員能夠立即采取積極有效措施避免車輛處于危險(xiǎn)行駛狀況，最終達(dá)到降低高速公路交通事故的目的。目前，全球一些知名汽車企業(yè)已經(jīng)將汽車防撞預(yù)警技術(shù)應(yīng)用于汽車主動(dòng)安全產(chǎn)品中，我國(guó)也在此領(lǐng)域中積極探索，努力將汽車防撞預(yù)警技術(shù)向產(chǎn)品化推進(jìn)。 本文在選取合適的測(cè)距傳感器以及建立理論行車安全車距模型上做了大量工作，通過(guò)對(duì)比和本裝置的開(kāi)發(fā)要求，選取激光傳感器作為高速公路上的測(cè)距裝置，，以DSP2812作為核心處理器，并且設(shè)計(jì)了相應(yīng)的車速采集模塊、顯示模塊和語(yǔ)音報(bào)警模塊，開(kāi)發(fā)出了硬件電路板，并根據(jù)相關(guān)算法編寫(xiě)了對(duì)應(yīng)程序。最后在高速公路上進(jìn)行了大量的實(shí)車試驗(yàn)，檢測(cè)本裝置硬件工作的穩(wěn)定性和算法可靠性，不斷對(duì)算法中的參數(shù)進(jìn)行優(yōu)化，使其能更加接近汽車運(yùn)行的真實(shí)狀況，達(dá)到有效避免高速公路上交通事故發(fā)生的目的。試驗(yàn)結(jié)果表明此裝置在高速公路上能夠有效起到預(yù)警作用，使駕駛員快速采取適當(dāng)措施避免交通事故的發(fā)生，這為今后開(kāi)發(fā)相關(guān)成熟產(chǎn)品打下了堅(jiān)實(shí)的基礎(chǔ)。
[Abstract]:The vehicle anti-collision warning device can send out warning signals through voice equipment when driving safety distance is not controlled, so that the driver can immediately take active and effective measures to avoid the vehicle from being in a dangerous driving condition. Finally achieve the goal of reducing highway traffic accidents. At present, some well-known automobile enterprises in the world have applied anti-collision warning technology to automotive active safety products, and our country has also actively explored in this field, and made great efforts to promote the anti-collision warning technology to production. In this paper, a great deal of work has been done on selecting the appropriate ranging sensor and establishing the theoretical vehicle distance model for driving safety. By comparing with the development requirements of this device, the laser sensor is selected as the ranging device on the highway. With DSP2812 as the core processor, the corresponding speed acquisition module, display module and voice alarm module are designed, the hardware circuit board is developed, and the corresponding program is compiled according to the relevant algorithm. Finally, a large number of real vehicle tests are carried out on the freeway to detect the stability of the hardware and the reliability of the algorithm, and to optimize the parameters of the algorithm continuously, so that it can be more close to the real condition of the vehicle operation. To achieve the purpose of effectively avoiding traffic accidents on the highway. The test results show that the device can play an effective role in early warning on expressway, and make the driver take appropriate measures to avoid traffic accidents quickly, which lays a solid foundation for the development of related mature products in the future.
