摘要： A route control system includes a status measuring unit, a cost management unit, a route determining unit, and a route setting unit. The status measuring unit checks a status of each node included in a network. The status is a wake state or a sleep state. The cost management unit updates a link cost for a link connected to a node in the wake state to a value smaller than any link cost for a link connected to a node in the sleep state. The route determining unit determines an optimum route connecting a first terminal to a second terminal. A sum of the link costs for the optimum route is lowest among the link costs for other available routes connecting the first terminal to the second terminal. The route setting unit sets a requested data flow in the optimum route.

摘要： A vehicle dynamics behavior reproduction system capable of describing accurately behavior of a motor vehicle in a lateral direction even for nonlinear driving situation includes a vertical wheel force arithmetic means (105), a lateral wheel force arithmetic means (110), a cornering stiffness adaptation means (115), a state space model/observer unit (120), a selector (130), a delay means (135), and a tire side slip angle arithmetic means (125). Vertical wheel forces (FZij) and tire side slip angles (αij) are determined by using sensor information and estimated values while lateral wheel forces (FYij) are determined in accordance with a relatively simple nonlinear approximation equation. The lateral wheel force (FYij) and the tire side slip angle (αij) provide bases for adaptation of cornering stiffnesses at individual wheels. Vehicle motion is accurately described to a marginal stability by using adapted cornering stiffnesses (Cij) and other information.

摘要： An on-board power line communication system that performs power line communication during charging and discharging of a battery prevents electromagnetic wave leakage from a power line from interfering with other on-board devices. A vehicle includes a PLC communication device that performs PLC communication using a charging cable that is connected to a battery, and an interference suppressor that prevents electromagnetic wave leakage from the charging cable, which accompanies PLC communication, from interfering with the operations of an on-board electronic device. The interference suppressor reduces electromagnetic wave leakage from the charging cable by reducing the output frequency of the PLC communication device or the value of current flowing through the charging cable while the on-board electronic device is performing a specific operation that will be affected by interference from PLC communication.

摘要： A driving situation detection system capable of detecting driving situations swiftly with high reliability is obtained. The driving situation detection system includes real curve arithmetic means reference vehicle model and observer means, a differentiator unit, a model curve radius arithmetic means, and an assessment unit. The arithmetic means generates real curve radius signals based on wheel speeds. The reference vehicle model and observer means processes input signals utilizing a linear reference model to generate a yaw rate signal and a vehicle body side slip angle signal. The unit differentiates the vehicle body side slip angle signal to generate a vehicle body side slip rate signal. The model curve radius arithmetic means generates a model curve radius signal based on the yaw rate signal and the vehicle body side slip rate signal. The assessment unit detects undesirable driving situations by comparing the real curve radius and the model curve radius.
