TRW Automotive Holding has announced that it will launch a new system for the detection of pedestrians and prevention of accidents at a “ride and drive” event, which will be held in Germany.
The detection system will interpret data from radar sensors and a video camera through a set of signal processing algorithms. This data will be combined with the electronic stability control system and help in braking the vehicle automatically when there is a possibility of a collision. The video camera used in the system has 24GHz radar which confirms the presence of a pedestrian that has been detected through the camera. Upon detection, the algorithms are set in motion to detect the probability of a collision. The driver is given a warning and the braking manoeuvre is automatically engaged, thus resulting in the slowing down of the vehicle. This also reduces the extent of impact of any collision.
The video camera is also capable of detecting lanes, traffic signs and other vehicles and can also detect pedestrians at distances of up to 40 m. The cameras can function with the same level of efficiency even during situations where the road is crowded and there are more than one pedestrian. The radar device that has been added through sensor fusion allows the vehicle to brake at high speeds. The new system can also be added to the already existing pedestrian protection safety system in which sensors are fixed in front of the vehicle to detect an actual collision. Additional safety devices such as pyrotechnic hood lifters can also be added to protect pedestrians in a better manner when there is a collision. The new detection system is likely to be in production by 2014.
