[WapCar] When the vehicle collided with the pedestrian, through active and passive technology, energy-absorbing materials and buffer zone, the damage to the pedestrian caused by collision will be reduce as much as possible.
Protective hood
The pressure sensors of front bumper is used to detect whether the pedestrian collision accidents occurs, and then a special lifting mechanism is used to lift the engine compartment cover a certain height. Therefore when pedestrian's head or torso collided with the compartment cover, more buffer space can be obtained, and a violent collision with rigid engine block is avoided.
Pedestrian airbag outside the car
From the sensor monitoring of the front bumper, if there is a collision with the pedestrian, the engine compartment cover will automatically lift a certain height. At the same time, the airbag hidden inside is released, wrapping the front windshield glass and A-pillar that may cause greater damage, achieving the effect of cooperative protection between the active engine compartment cover and the airbag.
Radar, camera detection with prompt sound
The above two kind of pedestrian protection belong to passive safety technology of automobiles, as well as active pedestrian protection. Pedestrians are detected in advance through radar and webcam, and the received signal will be transmitted to ECU, after judgement the ECU will give instructions to the executive agency, and at this time the vehicle will use the sound and light reminders in the car to warn the driver. If the driver doesn't take any measures because of factors such as fatigue driving, the active brake assist system will intervene in time when a collision is going to occur. However the active brake assist system does not stop the vehicle immediately, the ECU will consider the current speed and driving conditions in the front and rear to determine whether to decelerate or stop in an emergency.
For low-speed electronic vehicles with low noise and imperceptible noise, they are also equipped with horns that actively prompt pedestrians, which will emit low-frequency sound to prompt the presence of pedestrian vehicles.
