A method for determining a parameter representative of the state of vigilance of a vehicle driver, on the basis of information, termed TLC values, representative of the residual time before the vehicle crosses a traffic line, includes, at each instant t0 of measurement of a TLC value, calculating an indicator parameter representing the state of vigilance PerTLC(t0) such that: PerTLC  ( t   0 ) = ∫ α M   I   N α M   AX  PerTLC  ( W  ( α ) , α )   α with: PerTLC(W(α),α)=percentage of time during which the TLC value is below a threshold α in a time window W(α), [αmin-αmax] determined range of values α expressed in units of time and W(α) monotonic function. |
