PROBLEM TO BE SOLVED: To reduce a mental load on a driver.SOLUTION: An onboard system includes residual quantity sensing means that senses a residual quantity of a power source remaining in a vehicle, lighting sensing means that senses the fact that a power source residual quantity warning lamp disposed in the vehicle is lit, lighting residual quantity memory means that stores the power source residual quantity, which is sensed by the residual quantity sensing means, as a lighting residual quantity according to the timing that the lighting sensing means senses the fact that the power source residual quantity warning lamp is lit, notification residual quantity sensing means that senses a power source residual quantity which is larger by a predetermined quantity than the lighting residual quantity stored in the lighting residual quantity memory means, and notification means that notifies of information, which prompts replenishment of the power source, before the lighting residual quantity is sensed after the power source residual quantity larger by the predetermined quantity than the lighting residual quantity has been sensed.SELECTED DRAWING: Figure 1 |
