Claim 10:
11. A vehicle control system for controlling a state of a vehicle, the vehicle control system comprising:
sensors;
a control target;
an ECU configured to calculate control instruction data for the control target, which varies the state of the vehicle, in accordance with detection data output from the sensors; and
a vehicle control interface box including a temporary storage buffer, a non-volatile memory and a microcomputer, wherein the microcomputer is configured to execute processing of:
sampling and storing, in the temporary storage buffer, at a predetermined sampling period, the control instruction data that instructs the control target to vary the state of the vehicle;
checking whether the state of the vehicle has a predetermined high possibility of accident as a result of driving control of the vehicle by the control target when the state of the vehicle is other than the state of the predetermined high possibility of accident;
setting a sampling period for selecting the control instruction data stored in the temporary storage buffer in accordance with the state of the vehicle such that the sampling period is changed to a predetermined short sampling period when the state of the vehicle is determined to have the predetermined high possibility of accident; and
selecting and storing in the non-volatile memory, at the sampling period set in processing of setting the sampling period, the control instruction data stored in the temporary storage buffer,
wherein:
the vehicle interface box further includes a sampling period table which links the state of the vehicle and the sampling period; and the microcomputer changes the sampling period in correspondence to the state of the vehicle by referring to the sampling period table and setting the sampling period corresponding to the state of the vehicle;
the temporary storage buffer stores a plurality of types of control instruction data; and
the sampling period table links the driving state of the vehicle and the sampling period for each of the plurality of types of control instruction data.
