Vehicular drive assist system and vehicular drive assist method

A vehicular drive assist method, comprising:

• receiving, from more than one vehicle, a vehicular state and a present position of at least one vehicle;
• performing statistic processing of the vehicular state received, separately for each predetermined area on a road, by using the present position of the vehicle;
• calculating a tendency of the vehicular state separately for each predetermined area;
• evaluating whether there is a high need for attention on the road in the predetermined area from the tendency calculated;
• and
• sending a result of evaluation to at least one vehicle.

A vehicle-mounted apparatus, comprising:

• a sending/receiving portion that sends a vehicular state to a non-vehicular mounted communication center and that receives from the communication center a result of evaluation that indicates whether there is a high need for attention on a road in a predetermined area;
• a host vehicle position detection portion that detects a present position of a host vehicle;
• a vehicular state detection portion that detects a vehicular state of the host vehicle;
• a storage portion that stores and retains map information and the result of evaluation;
• a vehicle control portion that carries out a vehicle control of the host vehicle;
• and
• a main control portion that controls the sending/receiving portion so that the present position of the host vehicle detected by the host vehicle position detection portion and the vehicular state of the host vehicle detected by the vehicular state detection portion are sent to the communication center, and controls the storage portion so that the result of evaluation received from the communication center is stored and retained, and controls the vehicle control portion so that the vehicle control of the host vehicle is carried out based on the result of evaluation stored and retained in the storage portion.
