In addition, the inter-vehicle distance control device 1 and the lane departure prevention device 2 of the other vehicle can be operated to ensure a sufficient surrounding inter-vehicle distance.

  Thereby, for example, when a vehicle traveling in an adjacent lane makes an inadvertent lane change and approaches the host vehicle, the lane change can be suppressed and the risk of contact with the host vehicle can be reduced.

  In this embodiment, the driver explicitly requests the transmission of the operation signal, but the distance between the vehicles is measured by the distance sensor 5 provided at the rear or side of the vehicle, and the distance between the vehicles is a threshold value. An operation signal can be automatically transmitted in the following cases. It is desirable to make this threshold variable according to the running speed (for example, 30 m at 40 km / h and 80 m at 80 km / h).

  As described above, the vehicle control system according to the present invention can operate the accident avoidance device such as the inter-vehicle distance control device and the lane departure prevention device that the surrounding vehicle has from the own vehicle, thereby reducing the risk of an accident occurring. This is effective as a vehicle control system that secures the distance between the host vehicle and other vehicles.
