And Control

The use of in-car networked electronic controller units (ECUs) for monitoring and control of various vehicle subsystems has become a common practice among the automotive manufacturers. In this chapter, the author surveys one of the most popular in-car networking technologies, the Controller Area Network (CAN), as well as newer and emerging in-car network technologies called FlexRay and Media-Oriented System Transport (MOST). Currently, these networks are deployed for in-car applications such as engine diagnostics, and infotainment systems. In this chapter, however, the author extends the use of these embedded vehicular networks by proposing to remotely monitor and control the vehicles through them, in order to realize safety and driver assistance related applications. To accomplish this task, additional technologies such as real-time wireless communications and data security are required, and each of them is introduced and described in this chapter.

Narrow Bandwidth

Doppler Global Velocimeters (DGV) requires a narrow bandwidth laser beam which can be accurately tuned to a desired frequency. One laser used for this application is an ND-YAG which is seeded using a laser diode. By adjusting the laser diode output, the frequency of the ND-YAG laser beam can be modified. This technique also narrows the bandwidth of the laser frequency to below 100 MHz. Monitoring this output is difficult due to the 9 ns pulse duration which makes normal interferometry techniques ineffective for the 10 to 20 MHz frequency resolution required. This paper will describe a system constructed to monitor the frequency in real time which can be used in conjunction with a DGV system to correct for laser frequency drift. The particular ND-YAG system response and stability will be presented and discussed in relationship to DGV system accuracy.
