1. Pedestrian impact protection Introduction
Protective hood
detects a pedestrian collision has occurred by the pressure sensor on the front bumper, and then raised in a short time using a special the bonnet lifting mechanism at a distance, so that when the pedestrian’s head or torso with machine hatch impact occurs, can be obtained more buffer space, to avoid the violent collision with the more rigid body from the engine.
layman vehicle airbag
by a sensor monitoring the front bumper, if a collision with a pedestrian, the bonnet tail It will lift automatically a certain height, while hiding inside the airbag release, wrapped around the front part of the windshield and a-pillar may cause greater damage, to the effect of the engine compartment lid and the active collaboration airbag protection.
radar, cameras detect and accompanied by a tone
both belong to the protection of pedestrians automotive passive safety technologies, but also there are active pedestrian protection. Radar, a camera to detect pedestrians ahead, copies of the received signal to the ECU, the ECU determines whether the instruction issued to the actuator, then the vehicle will use sound to alert the vehicle light warn the driver, the driver if the driver due to fatigue and other factors did not make any response, active brake assist system immediately before the collision will be timely intervention. But the active brake assist system is not an immediate brake to stop the vehicle, because the ECU will be considered based on the current vehicle speed and front and rear driving conditions, the following is a deceleration traveling up or an emergency brake stop.
