Almost one in five accidents with physical injuries can be attributed either to inappropriate speed (16 percent) or to insufficient stopping distance (12 percent). Inattentiveness behind the wheel or inadequate stopping distance contributes to this. A solution is offered in the form of Hella’s distance-warning system based on the 24 GHz radar sensor. It continuously measures the distance to the vehicle driving in front and warns acoustically, optically or haptically if the distance preset by the driver is undercut.
The system is based on the innovative 24 GHz radar sensor. It emits an electromagnetic wave via an aerial. This is reflected by objects in the sensor’s visual range, and is received and evaluated. Precise determination of distance, angle and relative speed of the objects, correct lane classification and the detection and differentiation of roadside structures open up potential for further applications, such as the ACC speed and distance-regulation system, or a pre-crash function.
The 24 GHz radar-sensor technology was successfully developed in 2006 for a lane change assistant in the Audi Q7.
The first series use of the 24 GHz-based distance-warning system is planned for the year 2009. Due to the high cost-benefit efficiency, Hella has found a way with the aid of the 24 GHz radar technology of considerably increasing the prospects of a higher equipment rate in the medium class as well.
