Claim 0:
1. A vehicle control system for controlling a traveling state of a vehicle, the vehicle control system comprising:
at least one microcomputer;
a storage buffer; and
a non-volatile memory,
the at least one microcomputer is configured to
sample and store in the storage buffer, at a predetermined sampling period, control instruction data that instructs a control target to vary the travelling state of the vehicle;
change a sampling period for selecting the control instruction data stored in the storage buffer in accordance with a driving state of the vehicle such that the sampling period is set to a predetermined short sampling period, when the driving state of the vehicle becomes to have a predetermined high possibility of accident as a result of driving control of the vehicle when the driving state of the vehicle is other than the driving state of the predetermined high possibility of accident; and
select and store in the non-volatile memory, at the sampling period which is set, the control instruction data stored in the storage buffer,

wherein:
the at least one microcomputer includes a sampling period table which links the driving state of the vehicle and the sampling period, and changes the sampling period in correspondence to the driving state of the vehicle by referring to the sampling period table and setting the sampling period corresponding to the driving state of the vehicle;
the 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.
