An information notification system notifies a user of a vehicle of information. A first condition is that one or more time-designated speed limit signs recognized by a camera mounted on the vehicle designate all times of day as a whole. The information notification system determines whether or not the first condition is satisfied. When the first condition is not satisfied, the information notification system notifies the user of at least a legal speed limit on a road on which the one or more time-designated speed limit signs are installed, based on reference information on the legal speed limit in a region in which the vehicle is used.

The throttle valve control device of this invention controls a throttle based on outputs of a position sensor including a first sensor and a second sensor which detect a position of a same object, wherein the output of the first sensor and the output of the second sensor change opposite to each other depending on a change in the position of the object, and the throttle valve control device determines the position sensor abnormal when a variation in the output of the first sensor is equal to or greater than a first threshold value and a variation in the output of the second sensor is equal to or greater than a second threshold value.
