156-606: A lane departure warning system ( LDWS ) is a mechanism designed to warn the driver when the vehicle begins to move out of its lane (unless a turn signal is on in that direction) on freeways and arterial roads . These systems are designed to minimize accidents by addressing the main causes of collisions: driver error, distractions and drowsiness. In 2009 the U.S. National Highway Traffic Safety Administration (NHTSA) began studying whether to mandate lane departure warning systems and frontal collision warning systems on automobiles. There are four types of systems: Another system
208-494: A start-stop system based on the Valeo i-StARS reversible starter/alternator, and termed e-HDi for diesel models and e-THP for petrol models. Two "ultracapacitors" are charged during braking, and the energy stored in them is used to turn the i StARS when engine restart is required. According to PSA, the system is able to restart the engine in as little as 400ms, and while the vehicle is still moving at between 8–20 km/h, which
