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.
