IN-VEHICLE RECORDING SYSTEM AND IN-VEHICLE CONTROL APPARATUS

摘要

An in-vehicle control apparatus is connected with a gateway apparatus via a first in-vehicle network, and transmits a state of a trigger for recording state data representing a state of a vehicle and the like on a non-volatile memory. The in-vehicle control apparatus includes a determination unit to determine whether predetermined events have been generated; a setting unit to set the state of the trigger of the generated event, to a satisfied state; a transmission process unit to transmit a communication frame that conveys the state of the trigger for each event, to the first in-vehicle network; and a latch process unit to maintain the satisfied state of the trigger until a predetermined time passes, and to change the state of the trigger from satisfied to unsatisfied after the predetermined time has passed, for each of the triggers.

主权项

1. An in-vehicle recording system, comprising:
a first control apparatus configured to transmit to a first in-vehicle network a state of a trigger for recording state data that represents a state of a vehicle or an occupant of the vehicle, on a non-volatile memory; a gateway apparatus configured to relay the state of the trigger transmitted to the first in-vehicle network, from the first in-vehicle network to a second in-vehicle network; and a second control apparatus configured to receive from the second in-vehicle network, the state of the trigger relayed by the gateway apparatus from the first in-vehicle network to the second in-vehicle network; wherein the first control apparatus includes a generated event determination unit configured to determine whether a plurality of predetermined events have been generated in the vehicle, for each of the events, a trigger state setting unit configured to set the state of the trigger corresponding to the event having been determined as generated in the vehicle by the generated event determination unit, to a satisfied state, a transmission process unit configured to transmit a communication frame that conveys the state of the trigger for each of the events, to the first in-vehicle network, wherein the gateway apparatus includes a relay process unit configured to relay a second communication frame from the first in-vehicle network to the second in-vehicle network, without relaying a first communication frame, in a case where the gateway apparatus has received the second communication frame different from the first communication frame from the first in-vehicle network after having received the first communication frame from the first in-vehicle network, before relaying the first communication frame to the second in-vehicle network, wherein the second control apparatus includes a data recording unit configured to record the state data corresponding to the trigger set to the satisfied state among the triggers of the events in a communication frame received from the second in-vehicle network, on the non-volatile memory, wherein the first control apparatus includes a latch process unit configured to execute a latch process for maintaining the state of the trigger set to the satisfied state until a predetermined time passes since the trigger state setting unit has set the state of the trigger to the satisfied state, and changing the state of the trigger from the satisfied state to an unsatisfied state after the predetermined time has passed, for each of the triggers of the events.
