For example, when the traffic signals turn amber when approaching the intersection, a driver normally has to judge whether to pass it or stop in a moment in consideration of the speed of the vehicle and situation of vehicles ahead and around. This system supports drivers in making judgment for safe driving using infrastructure of traffic control systems. Therefore, we theoretically estimate dilemma zones and proper positions to supply information in accordance with the speed of vehicles, and then conduct verification test on the test field.","PeriodicalId":191336,"journal":{"name":"Proceedings of the IEEE International Vehicle Electronics Conference (IVEC'99) (Cat.

It gives consistent estimation of parameters of linear and nonlinear components separately, so every step is easy to explore. HOS makes this algorithm insensitive to any i.i.d. noise. The variable step of the adaptive algorithm gives fast convergence rate. Our experiments on a microbus show that the proposed approach gives a system function that precisely describes the transfer of engine noise.","PeriodicalId":191336,"journal":{"name":"Proceedings of the IEEE International Vehicle Electronics Conference (IVEC'99) (Cat.

This paper describes an ignition control system, whose core is a micro-processor (80C552). The inputs include intake manifold pressure sensor, throttle position sensor, water temperature sensor, crankshaft position (speed) sensor, synchronization sensor and knock sensor. The software of the system includes main flow program and several interruption programs. The article describes how the knock signal acquisition, knock condition judgment, ignition-signal, etc. are controlled by the software. The peak-value of the knock signal is recorded in a circuit during one cycle, and accordingly this value of the knock is detected. A new two-parameter ignition angle adjusting method is used, which is according to the peak-value of knock signal during one cycle and the mean value of several cycle peak-values. This method effectively resolved the contrast of the high response and small cycle fluctuation of ignition angle control. The experiments on 368Q engine shows that the design of the system hard-and-software is feasible and the engine is prevented from knock effectively, the torque of the engine is improved.","PeriodicalId":191336,"journal":{"name":"Proceedings of the IEEE International Vehicle Electronics Conference (IVEC'99) (Cat.
