摘要： The present disclosure provides a method and an apparatus for reducing a communication load in controller area network (CAN) communication. A method for reducing communication load in a transmission node connected to a CAN communication network may include: generating a first CAN data frame including first data and transmitting the first CAN data frame to the CAN communication network at a first transmission time; comparing second data with the first data at a second transmission time; and transmitting, to the CAN communication network, a second CAN data frame in which a data length code (DLC) field value is set to a predetermined value indicating that the data has not changed, when the second data is identical to the first data. Accordingly, CAN communication load can be effectively reduced without CAN hardware modification.

摘要： A message generation module generates a message that is to be transmitted to a serial data bus of the vehicle once per first predetermined period. A queue manager module resets a timer value when the message is added to a transmit queue and selectively adds the message to the transmit queue when: a number of messages in the transmit queue is less than a first predetermined value; the timer value is greater than the first predetermined period; and one of (i) the first predetermined period is less than a second predetermined period and (ii) the first predetermined period is greater than the second predetermined period and the number of messages in the transmit queue is less than a second predetermined value. The second predetermined value is less than the first predetermined value. A communication control module selectively transmits messages from the transmit queue to the serial data bus.

摘要： The invention relates to a cyclical time-based communication system, for the transmission of useful data (DATA) between users of the system, which comprises a databus and users connected thereto. The data transmission occurs within cyclical repeating timeframes, each with at least two timeslots. Each timeslot is provided for the transmission of a message (Ni). A message (Ni) comprises at least part of the useful data (DATA) and each message (Ni) is provided with a code (ID). The bandwidth available for data transmission may be better utilized, if the code (ID) is placed within the message (Ni) as a part thereof, each message (Ni) is additionally provided with time information concerning the timeslot which may be extracted from the code and at least one of the timeslots within the timeframes may be used for transmission of various messages in various cycles. In a preferred embodiment the information relating to the current cycle comprises an ordinal number for the cycle. In the simplest case the number has two values 0 and 1. Even and odd cycles can thus be differentiated. The ordinal number may be increased to differentiate more cycles from each other. The transmission method is preferably based on the FlexRay protocol.

摘要： An object of the present invention is to provide a sending apparatus, sending method and a communication system with utilizing the sending apparatus that can improve efficiency of data sending operation and can reduce a duty for data communication. Each sending apparatus classifies data stored on a storage into groups “X”, “Y” and “Z”, fractionates a clump of data, classified into each of the groups “X”, “Y” and “Z”, by a number of fractions based on a sending completion allowable time for the classified data, and sends the fractionated data in multi cycles at every sending interval, without sending and receiving the data stored on the storage all at once. Each sending apparatus selects any one piece of data generated from fractionated clump of data for each of the groups “X”, “Y” and “Z”, and then sends the selected piece of data at every sending interval.

摘要： The present invention discloses a communication terminal included in a network system in which a plurality of communication terminals are connected to a single transmission medium. A priority information acquisition section (11) acquires priority information contained in a currently transmitting packet. A priority determination section (13) determines, based on priority information contained in a to-be-sent packet and the priority information acquired by the priority information acquisition section (11), which one of the to-be-sent packet and the currently transmitting packet should be given priority. A jam signal generation section (14) generates a jam signal if it is determined by the priority determination section (13) that the to-be-sent packet is given priority. A communication section (15) sends out the to-be-sent packet on the transmission medium after the jam signal stops and before the currently transmitting packet is sent out again.
