Abstract:
1. A travel safety system for a vehicle, comprising: an object detecting means for detecting an object existing in a travel direction of the vehicle; a correlation calculating means for calculating a correlation including a relative position of the object to the vehicle based on a result of the detection by the object detecting means; a safety device comprising a primary warning means, and a secondary warning means, wherein the secondary warning means is actuated when a possibility of the vehicle contacting the object is higher than that needed for operation of the primary warning means; and a safety device operation control means for determining presence or absence of a possibility of contact between the vehicle and the object based on the correlation calculated by the correlation calculating means, and controlling the operation of the safety device, wherein the safety device operation control means actuates the primary warning means when a duration of time for which the object exists in a primary predetermined region where there is the possibility of contact with the vehicle is equal to or larger than a primary predetermined period, and actuates the secondary warning means when a duration of time for which the object exists in a secondary predetermined region where there is the possibility of contact with the vehicle is equal to or larger than a secondary predetermined period, and wherein the primary predetermined period is longer than the secondary predetermined period.
