Apparatuses and methods for providing improved in-vehicle warnings are disclosed. A driver's prior driving performance and a summary representation of that performance may be used as parameters in a hazard or collision warning algorithm. Information from sensors regarding the vehicle, driver, and external traffic and roadway conditions may be used to estimate driver performance variables in particular driving situations. Each driver performance estimate may be included into one or more overall summary variables for that driving situation. The value of these summary variables may then be used in an algorithm to control the nature and timing of a warning, when a similar situation arises again in the future.

The invention claimed is: 1. A method of controlling presentation of vehicle hazard warnings to a driver of a vehicle by an in-vehicle warning apparatus, the method performed by the in-vehicle warning apparatus comprising the steps of: identifying the driver of the vehicle; detecting a driving situation based upon information from one or more sensors; detecting a potential driving hazard; predicting a response time for the identified driver to avoid the hazard in the driving situation based upon stored information regarding past performances of the identified driver in one or more similar driving situations; determining an estimated time to the hazard; comparing the predicted response time to the estimated time to the hazard; determining whether to provide a warning to the identified driver, based upon the act of comparing; and if the act of comparing indicates that the warning should be provided, determining one or more modalities of presentation of the warning. 2. The method of claim 1, wherein the driving situation comprises following a lead vehicle. 3. The method of claim 2, wherein the driving hazard comprises deceleration of the lead vehicle. 4. The method of claim 1, further comprising the steps of: measuring an actual response time for the identified driver; and updating the stored information regarding the past performances of the identified driver, based upon the actual response time for the identified driver. 5. The method of claim 1, wherein the one or more modalities of presentation comprises visual presentation. 6. The method of claim 1, wherein the one or more modalities of presentation comprises auditory presentation. 7. The method of claim 1, wherein the one or more modalities of presentation comprises haptic presentation. 8. The method of claim 1, further comprising the step of determining a starting time for the warning based upon the identity of the driver and the stored information regarding past performances of the identified driver. 9. The method of claim 1, further comprising the step of determining an intensity for the warning based upon the identity of the driver and the stored information regarding past performances of the identified driver.
