A vehicle control system may include a power generator, a storage battery, a running electric motor, a determiner configured to determine an area toward which a vehicle occupant of the vehicle has a line of vision directed; a deriver configured to derive an index based on a frequency at which the vehicle occupant has the line of vision directed toward a specific area on the basis of a determination result; and a controller configured to operate the power generator in a case in which an amount of power of the storage battery is equal to or smaller than a threshold and operate the power generator regardless of the threshold of the amount of power of the storage battery in a case in which the index derived is equal to or higher than a predetermined degree.

An exhaust gas purifying apparatus for an internal combustion engine, in which a NOx absorbing catalyst and a NOx concentration sensor for detecting a NOx concentration in exhaust gases of the engine, are provided in an exhaust passage of the engine. A rich spike for temporarily enriching the air-fuel ratio is performed, and an execution timing of the rich spike is determined based on a detected output from the NOx concentration sensor. Performing the rich spike is determined to be unnecessary during a reducing state period from the time the rich spike ends to the time a preset time period has elapsed, and is also determined to be unnecessary when a change tendency of the detected output is determined to be an output decreasing state where the detected output is decreasing. The execution timing of the rich spike is determined using the detected output when the change tendency is determined to be an output staying/increasing state where the detected output is staying at a constant value or increasing after the end timing of the reducing state period.
