KWP2000协议分析

男作者
在汽车故障诊断领域,针对诊断设备和汽车ECU之间的数据交换,各大汽车公司几乎都制订了相关的标准和协议。其中,欧洲汽车领域广泛使用的一种车载诊断协议标准是KWP2000(Keyword Protocol 2000),该协议实现了一套完整的车载诊断服务,并且满足E-OBD(European On Board Diagnose)标准。KWP2000最初是基于K线的诊断协议,由于K线物理层和数据链路层在网络管理和通讯速率上的局限性,使得K线无法满足日趋复杂的车载诊断网络的需求。而CAN网络(Controller Area Network)由于其非破坏性的网络仲裁机制、较高的通讯速率(可达1M bps)和灵活可靠的通讯方式,在车载网络领域广受青睐,越来越多的汽车制造商把CAN总线应用于汽车控制、诊断和通讯。近年来欧洲汽车领域广泛采用了基于CAN总线的KWP2000,即ISO 15765协议,而基于K线的KWP2000物理层和数据链路层协议将逐步被淘汰。

"I'm glad we could make a deal," the salesman says, shaking your hand.

But just as you've breathed a sigh of relief, you realize that you are walking into the Finance and Insurance (F&I) office to finalize the contract. Once inside that room, the F&I manager will likely offer you things like paint protection, prepaid maintenance plans, theft-recovery systems and a road-hazard warranty for your tires. But the biggest product he'll probably push will be the extended warranty for the car itself. Extended warranties, also known as "service contracts," can provide peace of mind to some car buyers. Car dealerships like them because they are an additional profit center for the business. As with any decision in a car purchase, it is important for you to research and weigh the benefits of the product.

What if I Unknowingly Purchase a Flood-Damaged Car?

男作者

If you recently bought a used or new vehicle that you suspect has flood damage, all is not lost. State and federal lemon laws are in place to protect consumers. But you’ll want to be diligent about getting to the bottom of this. 

That’s because water damage to a vehicle is serious business. In fact, you could be saddled with the following problems:
