摘要： When a message is transmitted, frame by frame, from any one (10) of a plurality of multiplex nodes to a common multiplex bus (MB) to which the multiplex nodes are connected, each of the multiplex nodes (20 and 30) determines that transmission of a frame therefrom is allowed when it detects a transmission permission signal (b, b') added to the frame after detection of and idle state of the multiplex bus, and starts transmitting a message data frame. This makes it possible to properly implement priority-based control according to the priority levels of the data frames irrespectively of variations in the reference clocks of the multiplex nodes. Further, receiving multiplex nodes perform frame synchronization at the rise of a special code (a) of a start code (SOM) of a message data frame, and then perform re-synchronization at the rise of a special bit pattern (b") which includes a passive bit and a dominant bit. This prevents synchronization from being deviated and bit errors resulting from deviated synchronization, thus leading to higher reliability of multiplex transmission.
摘要翻译：当从多个多路复用节点中的任何一个（10）到多路复用节点连接的公共多路复用总线（MB）逐帧传输消息时，多路复用节点（20和30）中的每一个确定当检测到多路复用总线的检测和空闲状态之后检测到添加到帧中的发送许可信号（b，b'）时，允许发送帧，并开始发送消息数据帧。这使得可以根据数据帧的优先级来适当地实现基于优先级的控制，而与多路复用节点的参考时钟的变化无关。此外，接收多路复用节点在消息数据帧的起始码（SOM）的特殊码（a）的上升处执行帧同步，然后在特殊位模式（b“）的上升执行重新同步，其中包括无源位和占位。这防止了同步偏离和由偏差同步引起的位错误，从而导致更高的多路传输可靠性。

摘要： Communication nodes which respectively transmit periodic information and non-periodic information in multiplex fashion are provided separately. These communication nodes selectively transmit periodic information to a multiplex transmission line which is originally for transmitting the non-periodic information or non-periodic information to a multiplex transmission line which is originally for transmitting the periodic information in accordance with the state of transmission/reception of the periodic information and non-periodic information.

摘要： A hybrid type vehicle designed to use an engine and motor generators to drive the vehicle, wherein the engine is provided with a variable compression ratio mechanism and a variable valve timing mechanism. When the vehicle is backing up, one motor generator is used to generate an output for vehicle drive use. If the engine is made to operate at this time, the engine torque and the engine speed are made to change along a minimum fuel consumption rate operation line.

摘要： A vehicle multiplex transmission apparatus which can operate all the auxiliary units of a vehicle even when a power supply line of the vehicle is locally short-circuited. This vehicle multiplex transmission apparatus includes a plurality of control nodes arranged in respective portions of a vehicle, for controlling vehicle auxiliary units, and a multiplex transmission line for connecting among the plurality of control nodes. The control nodes are connected to a power supply node arranged at a predetermined position of a vehicle body through two independent systems of first and second power supply lines. The first power supply line supplies power to vehicle travel auxiliary units. The second power supply line supplies power to general system auxiliary units, but it can supply power to the travel auxiliary units as needed.
