Driver adaptive collision warning system
First Claim
1. A method for forewarning a driver of a potential collision comprising the steps of:
- (a) determining a driving style of a driver;
(b) determining timing for issuing a warning based on the determined driving style; and
(c) issuing the warning based on the determined timing, wherein the step of (a) comprises the steps of;
(i) collecting data corresponding to a plurality of parametric models (PMs) relating to driver attitude level of an individual driver;
(j) determining parametric model (PM) value distribution for each PM from the collected data;
(k) determining an average value for each PM value distribution; and
(l) determining a parametric-specific attitude level for each PM by mapping the average value for each PM value distribution to a pre-determined scale specific to each PM.

Abstract
The present invention involves methods and systems for issuing a collision warning to a driver at timing based on the driver'"'"'s attitude level. The methods involve the steps of determining the driver attitude level based on the driver'"'"'s actions in a plurality of driving conditions, determining timing for issuing warning based on the driver attitude level, and issuing warning based on the determined timing. The systems include a first device for collecting data associated with driver attitude, and a second device connected to the first device for determining a driver attitude level. The second device includes a processor for processing the data by applying pre-determined algorithm to determine the driver attitude level. The systems may further include a third device connected to the second device for determining timing for issuing warning corresponding to the driver attitude level, and issuing a warning according to the determined timing. Alternatively or additionally, the third device may include a software for enabling a determination of the rate of change in terms of acceleration and deceleration, and a control for affecting the rate of change. Further, the third device may include a software for enabling a determination of a safety distance and a distance control.
