1. An automatic travelling control system, comprising:
an automatic travelling controller that controls automatic travelling of a vehicle;
a function determiner that determines a status of a function used for the automatic travelling of the vehicle;
a first notifier that provides a notification of the status of the function;
a first abnormality detector that detects a first abnormality in the notification of the status of the function;
the automatic travelling controller that reduces, in the automatic travelling, a speed of the vehicle when the first abnormality in the notification of the status of the function is detected and the function is determined as being abnormal;
a second notifier that provides a predetermined notification when the first abnormality in the notification of the status of the function is detected and the function is determined as being normal;
a second abnormality detector that detects a second abnormality in the predetermined notification and that detects where the second abnormality occurs in the predetermined notification by checking signals processed by electronic control units of the vehicle, the electronic control units being related to a communication device of the vehicle, a global positioning system of the vehicle, and a sensor of the vehicle;
a manual driving capability determiner that determines whether a user on board the vehicle is capable of driving the vehicle manually; and
a manual driving requester that requests the user to drive the vehicle manually when the second notifier provides the predetermined notification and the manual driving capability determiner determines that the user is capable of driving the vehicle manually,
wherein the second abnormality detector, in detecting where the second abnormality occurs in the predetermined notification by checking the signals processed by the electronic control units, at least related to the communication device, the global positioning system, and the sensor, detects that the second abnormality occurs in a process of providing, transmitting, and outputting the predetermined notification, the second abnormality occurring in at least one of: equipment providing the predetermined notification; an output that outputs the predetermined notification; or
a transmission path between the equipment and the output.
