Warning system implemented in a vehicle and method thereof

Abstract

A warning system implemented in a vehicle includes an overspeed warning module and a display module. The overspeed warning module is configured to generate an overspeed warning signal when a speed of the vehicle exceeds a speed limit. The display module is configured to display an alerting signal perceptible by a driver when the overspeed warning signal is generated.

What is claimed is: 
     
         1 . A warning system implemented in a vehicle, comprising:
 an overspeed warning module configured to generate an overspeed warning signal when a speed of the vehicle exceeds a speed limit; and   a display module configured to display an alerting signal perceptible by a driver when the overspeed warning signal is generated.   
     
     
         2 . The warning system of  claim 1 , wherein the overspeed warning module comprises:
 a vehicle speed detecting module configured to obtain the speed of the vehicle;   a road information access module configured to retrieve the speed limit, wherein the speed limit corresponds to a road section; and   a vehicle electronic control unit coupled to the vehicle speed detecting module and the road information access module, and the vehicle electronic control unit is configured to generate the overspeed warning signal when the speed of the vehicle exceeds the speed limit.   
     
     
         3 . The warning system of  claim 1 , wherein the display module has an active display area, the active display area comprises a central area and a side area, the alerting signal is displayed in the side area, and the alerting signal is performed through color changes, adjustments of brightness, changes of shape, or a flashing indicator. 
     
     
         4 . The warning system of  claim 1 , wherein the display module comprises:
 a display panel; and   a plurality of light emitting units disposed around a boundary of the display panel and configured to illuminate a side area of the display module.   
     
     
         5 . The warning system of  claim 1 , wherein the display module is implemented in a vehicle instrument cluster, a central console panel, a rear-view display or a head-up display. 
     
     
         6 . A method for providing warnings, comprising:
 obtaining a speed of a vehicle;   retrieving a speed limit corresponding to a road section;   generating an overspeed warning signal when the speed of the vehicle exceeds the speed limit; and   displaying an alerting signal when the overspeed warning signal is generated.   
     
     
         7 . The method of  claim 6 , wherein the alerting signal is displayed in a side area of the display module, and the alerting signal is performed through color changes, adjustments of brightness, changes of shape, or a flashing indicator.
