Abstract
An anomaly handling method in an in-vehicle network includes: transmitting and receiving frames; detecting a frame having an anomaly; and switching, when the anomaly is detected in the detecting, a transmission timing of the frame in which the anomaly is detected. The switching includes changing a switched transmission timing to which the transmission timing is switched, according to predetermined information.
Claims15
An anomaly handling method in an in-vehicle network, the anomaly handling method comprising:
- transmitting and receiving messages;
- detecting a message having an anomaly;
- and
- switching, when the anomaly is detected in the detecting, a transmission timing of the message in which the anomaly is detected,
- wherein the switching includes changing a switched transmission timing to which the transmission timing is switched, according to predetermined information,
- a communication scheme in the in-vehicle network is a time trigger-type communication scheme based on time slots,
- the transmitting and receiving includes transmitting and receiving the message in a predetermined time slot,
- the switching includes determining a switched slot to which the transmission timing is switched, as the switched transmission timing,
- the time slots include a plurality of empty slots to each of which no message is assigned,
- the switching includes determining, as the switched slot, an empty slot according to the predetermined information, and
- the method further comprises:
- transmitting a synchronous message for sharing the switched slot.
