Vehicle & Infrastructure Safety Improvement in Adverse Conditions and Night Driving : The car that scans the road

In order to improve road safety, PSA Peugeot Citron has developed two new systems to warn the driver when the risk of an accident is detected. Both systems are using the same infrared sensors mounted behind the front bumper. These sensors are able to detect white markings on the road and can be used In two different ways: 1. Using lane markings on motorways or express roads, it turns into a lane departure warning system. 2. Using specific markings as bar codes, the car can "read" information from the road (speed limitation, dangerous curve...) and "give" this safety information to the driver. In such systems, the important is not only the way the danger is detected, but also the HMI solution chosen to warn the driver. After an ergonomic study, PSA Peugeot Citroen has developed different HMI solutions adapted to different situations.
