This Patented system with a low production cost can thus alert a driver about dangerous conditions while there is still time to correct them.
About
Summary Lane deviation warning systems (LDWS) are appearing on most mid- to upper-end vehicles beginning with model year 2014. These systems are helping reduce costs of insurance claims due to some types of collisions, but they lose effectiveness in low light and poor visibility conditions or when lane markers are absent or difficult to detect. Further, these systems tend to warn a driver of dangerous behavior after the point when countermeasures would be effective, and they are expensive. Research by WSU inventors Van Dongen and co-workers has shown that a steering wheel-based sensor and accompanying algorithm can be used to detect drowsiness at moderate levels. This Patented system with a low production cost can thus alert a driver about dangerous conditions while there is still time to correct them, and avoid danger and harm without relying on optical detection of lane deviations.
