Warning system for vehicles
First Claim
Patent Images
1. A warning system for a vehicle, which comprises:
- warning issuing means for issuing warnings when said vehicle approaches objects;
driving operation-detecting means for detecting a driving operation by a driver of said vehicle;
reaction time-calculating means for calculating a value of a reaction time from the time one of said warnings is issued by said warning issuing means to the time it is detected by said driving operation-detecting means that said driver starts said driving operation in response to the one of said warnings; and
warning control means for controlling timing at which another of said warning should be issued by said warning issuing means, based on the calculated value of said reaction time from prior said warnings.

Abstract
A warning system for a vehicle has a warning device for issuing a warning when the vehicle approaches an object. A warning timing parameter section detects a driving operation by the driver of the vehicle, and calculates a reaction time from the time a warning is issued by the warning device to the time the driver starts the driving operation in response to the warning. A warning control section controls the timing at which the warning should be issued by the warning device, based on the calculated reaction time.

6. A warning system for a vehicle, which comprises:
-
warning issuing means for issuing a warning when said vehicle approaches an object; driving operation-detecting means for detecting a driving operation by a driver of said vehicle; reaction time-calculating means for calculating a value of a reaction time from the time said warning is issued by said warning issuing means to the time said driving operation-detecting means detects that said driver starts said driving operation in response to said warning; memory means for storing values of said reaction times; and warning control means for controlling a timing at which said warning is issued by said warning issuing means, said warning control means including means for calculating an average value of reaction time of said driver based on a plurality of previously calculated said values of said reaction time calculated by said reaction time-calculating means, and said warning control means determining the timing at which said warning is issued by said warning issuing means as a predetermined time period before calculating said calculated average value and as based on said calculated average value after calculating said calculated average value. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17)
