| Research Abstract |
We have proposed communication systems achieving low latency and high reliability for in-vehicle network which is one of actuator control signal networks. We have evaluated the proposed systems and have shown their effectiveness with simulations and experimental trials. We have analyzed signal attenuation and impulsive noise over in-vehicle single-wire power lines through actual measurements and have shown the feasibility of low-rate in-vehicle networks achieving latency with bit time order and high reliability by differential binary phase shift keying (DBPSK) with differential detection. Furthermore, we have proposed short pulse line codes achieving controller area network (CAN), which is an international standard for in-vehicle networks, with high rate and high multiplexing for one pair of twisted pair cables. We have shown the effectiveness of short-pulse line codes with prototypes.
