Description
Technical Field
The invention belongs to an intelligent auxiliary driving System, in particular to a passive pedestrian protection and collision buffer protection System based on an Advanced Driving Assistance System (ADAS) sensor.
Background
The typical automobile type that uses collision buffering protection system is the Honda Accord, and the movable hinge has been installed at the tip that the bonnet lifted to the Accord, and when colliding the pedestrian, the hinge just can drive the bonnet and bounce to can reach the effect of buffering protection pedestrian, the room space of collision room that simultaneously front fender and bumper reserved also can play the cushioning effect.
Because the bonnet that has collision buffering protection system compares in ordinary bonnet, its production cost is higher, and collision buffering protection system once triggers, and its bonnet can only be maintained through the mode of whole change, and the "machine lid door" that the Honda pavilion explodes in earlier stage, collision buffering protection system is because the design sensitivity is higher to a great extent, appears hitting the phenomenon that the lid bounced that can both lead to the small animal or the rear-end collision, and many car owners all have a lot of to its murder. This goes against the definition that the impact protection system is limited to humans.
Disclosure of Invention
In view of the problems of the background art, it is an object of the present invention to provide an ADAS sensor based passive pedestrian protection and crash cushion protection system in which the objects of action are limited to humans only.
In order to achieve the purpose, the passive pedestrian protection and collision buffer protection system based on the ADAS sensor comprises a passive pedestrian protection and collision buffer protection system, and is characterized in that: utilizing FAS-Cam and front look-around camera on ADAS to identify the type of the target in front of the vehicle, if the vehicle is collided, if the result of the identification is that the vehicle is a person, then sending a popup signal to a passive pedestrian protection and collision buffer protection system by BCM or ACU, and after receiving the popup signal, the passive pedestrian protection and collision buffer protection system bounces up a cover to protect the pedestrian; if the vehicle collision is identified as non-human, the BCM or the ACU does not send an action signal to the passive pedestrian protection and collision buffer protection system. The FAS-Cam and front look-around cameras identify the type of object ahead of the vehicle and transmit it periodically to the BCM or ACU.
Preferably, the method for judging the person as the plantago target is as follows: the method for judging the plantago target person comprises the following steps: firstly, performing identification judgment by using FAS-Cam, and then performing identification judgment by using a front looking-around camera; and if the FAS-Cam is identified as non-human and the confirmation result of the front look-around camera is also non-human, judging that the type of the target in front of the vehicle is non-human, otherwise, judging that the type of the target in front of the vehicle is human.
Preferably, in the event of a collision, only the BCM or the ACU stores pedestrian signals from the FAS-Cam and/or the front looking-around camera and receives collision signals judged by the G value sensor and the pressure sensor, and the passive pedestrian protection and starting device is started when the current vehicle speed exceeds the minimum collision speed set by the manufacturer.
The invention has the beneficial effects that: the invention solves the problem of false bounce of the engine cover caused by collision with a non-human object, and greatly improves the economical efficiency of vehicle collision maintenance and the safety performance of the whole vehicle.

Detailed Description
The technical solutions of the present invention (including the preferred ones) are further described in detail by way of fig. 1 to 3 and enumerating some alternative embodiments of the present invention. It is to be understood that the described embodiments are merely a few embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without any inventive step, are within the scope of the present invention.
Embodiment one, as shown in fig. 1 and 2:
when the vehicle is running normally, the FAS-Cam (forward looking active safety camera) and the front look-around camera recognize the type of the object ahead of the vehicle and transmit it periodically to the BCM (vehicle body controller). After collision occurs, the G value sensor and the pressure sensor send signals to the BCM, the BCM can determine whether to trigger pedestrian protection according to the FAS-Cam and target type data identified by the front look-around camera, if the collision object in front of the vehicle is a person in the collision, the signals are sent to a pedestrian protection device, and a cover is bounced to protect the pedestrian; if the FAS-Cam and the front look-around camera judge that the collision object is not a person, the BCM does not start the passive pedestrian protection device.
The method for judging the plantago target person comprises the following steps: firstly, performing identification judgment by using FAS-Cam, and then performing identification judgment by using a front looking-around camera; and if the FAS-Cam is identified as non-human and the confirmation result of the front look-around camera is also non-human, judging that the type of the target in front of the vehicle is non-human, otherwise, judging that the type of the target in front of the vehicle is human.
When collision occurs, on the premise that the BCM periodically acquires the type of a vehicle front target, the BCM reads a speed value on an ESC (electronic stability control system) and judges whether the current speed exceeds a preset minimum collision speed. And only the pedestrian signals from the FAS-Cam and/or the front looking-around camera stored by the BCM are received from the collision signals judged by the G value sensor and the pressure sensor, and the passive pedestrian protection and starting device can be started when the current vehicle speed exceeds the minimum collision speed V set by the manufacturer.
Example two, as shown in fig. 3:
when the vehicle is running normally, the FAS-Cam (forward looking active safety camera) and the front look-around camera recognize the type of the object in front of the vehicle and transmit it periodically to the ACU (airbag system control unit). After collision occurs, the G value sensor and the pressure sensor send signals to the ACU, the ACU can determine whether to trigger pedestrian protection according to FAS-Cam and target type data identified by the front looking-around camera, if a collision object in front of the vehicle is a person in the collision process, a signal is sent to a pedestrian protection device, and a cover is bounced to protect the pedestrian; if the FAS-Cam and the front look-around camera judge that the collision object is not a person, the ACU does not start the passive pedestrian protection device.
The method for judging the plantago target person comprises the following steps: firstly, performing identification judgment by using FAS-Cam, and then performing identification judgment by using a front looking-around camera; and if the FAS-Cam is identified as non-human and the confirmation result of the front look-around camera is also non-human, judging that the type of the target in front of the vehicle is non-human, otherwise, judging that the type of the target in front of the vehicle is human.
When collision occurs, the ACU reads a speed value on an ESC (automobile electronic stability control system) on the premise that the ACU periodically acquires the type of a target in front of the automobile, and judges whether the current speed exceeds a preset lowest collision speed. And only the pedestrian signal from the FAS-Cam and/or the front looking-around camera stored by the ACU is received by the collision signal judged by the G value sensor and the pressure sensor, and the passive pedestrian protection and starting device can be started when the current vehicle speed exceeds the minimum collision speed V set by a manufacturer.
It will be understood by those skilled in the art that the foregoing is only a preferred embodiment of the present invention, and is not intended to limit the invention, and any modification, combination, replacement, or improvement made within the spirit and principle of the present invention is included in the scope of the present invention.
