The vehicle is positioned by GPS aided with dead reckoning. System controlling, data collecting and processing, and the navigation information output are done by the embedded hardware platform. The embedded AVN application software calculates the vehicle's geographic position, velocity, and the direction real-timly through the vehicle's positioning subsystem, selects the best driving path according to the demand, and does navigation processing, outputs the navigation information through electrical map and voice, which guide the driver to reach the destination quickly, safely, and straightly.

汽车定位子系统以GPS卫星定位为主、航位推算为辅进行汽车定位；嵌入式硬件平台进行系统控制、数据采集和处理、导航信息输出；嵌入式汽车自主导航软件通过汽车定位子系统，实时解算出车辆的地理位置、速度、方向等信息，并根据需求自动演算最佳行驶路线，在行驶过程中实时进行导航处理，同时将这些信息通过电子地图和语音提示的方式反映出来，从而引导驾驶员快速、安全、准确地到达目的地。

The main research work of this dissertation is as follows: Based on the chemical reaction engineering theory and the nitrobenzene electroreduction mechanism, the plate and frame electrolyzer was designed and applied to the process of electroreduction nitrobenzene to p-aminophenol. This dissertation measured the residence time distribution data of the electrolyzer by means of the pulse response method and studied the rule of flow pattern along with the current capacity change. Under different conditions ,this dissertation studied the cyclic voltammetry properties of nitrobenzene on different electrodes by means of the dynamic cyclic voltammetry method and the electrode materials applied to the NB electroreduction have been selected primarily.Baseed on the results of cyclic voltammetry tests, this dissertation used p-electrode systems to measure the steady-state- polarization curves of nitrobenzene on different electrodes in H-type diaphragm cell, and obtained each primary factor s influence rule and the exchange current density value of each electrode.And then on the basis of the conclusions of fundamental researchs upword, the effects of influence factors on the the yield of p-aminophenol and the current efficiency,such as electrode material, current density, quantity of electricity circulated, nitrobenzene concentration . sulpuric acid concentration and so on, have been studied in detail in the systems of hign temperature , strong acidity and oxygen-poorthrough a series of electrolysis experiments in this paper.After all using Pb as anode Monel metal as cathode Dupont Nafion 417 cation-exchange membrane as membrane, this dissertation obtained the optimum technological condition: reaction temperature about 85C, current density 500A m-2, sulphuric acid concentration 20%wt.
