| 1. | The subject of the invention is a method for reducing the consequences of pedestrian run overs. Description: The impact sensor placed in front of the vehicle (item 5) sends a signal to the control system, so that the control system sends a signal for suspending the braking, while sending a signal to inflate the airbags (item 2) placed under the front and the sides of the hood (item 3) of the vehicle (item 5). Following this the control system gives a signal for a new but gentle braking, resulting in vehicle (item 5) stopping. |
| 2. | Favorable solution is that during the method, the control system sends a signal for a slight acceleration to the engine almost at the same time with the signal for braking and this speeding lasts at least until the end of the inflation of the airbags (item 2). |

Method and system for the considerable reduction of consequences of pedestrian run overs.
The US 20420040108157Al marked patent file describes a system for the considerable reduction of consequences of pedestrian run overs. The system is equipped with pedestrian run over sensors. In case of impact, the control system operates a pedestrian protection system (airbag) under the hood of the vehicle. With this solution it is possible to reduce the injuries that happen in the accident between the vehicle and the pedestrian. However, during the impact phase, the driver is constantly emergency braking, therefore the injured pedestrian falls onto the pavement, the source of following injuries.
The goal of my invention is to avoid the further impact of the injured pedestrian with the pavement. This invention is a method for reducing the consequences of pedestrian run overs. Description: The impact sensor placed in front of the vehicle (item 5) sends a signal to the control system, so that the control system sends a signal for suspending the braking, while sending a signal to inflate the airbags (item 2) placed under the front and the sides of the hood (item 3) of the vehicle (item 5) . Following this the control system gives a signal for a new but gentle braking, resulting in vehicle (item 5) stopping.
Favorable solution is that during the method, the control system sends a signal for a slight acceleration to the engine almost at the same time with the signal for braking and this speeding lasts at least until the end of the inflation of the airbags (item 2).

Figure 1 depicts the pedestrian (item 4) and the vehicle (item 5) at the moment of impact. The impact sensors of the vehicle send signals to the control system at the moment the control system gives a signal for the suspension of braking, therefore, the vehicle keeps traveling with the speed it had at the moment of impact. Ideally, the control system sends signals to the engine for a gentle acceleration ensuring that the injured pedestrian stays on the hood. Meanwhile, the injured pedestrian is on the hood while the airbags inflate, followed by deceleration and thus ensuring that the injured person avoids impact with the pavement. For the same purpose, the control system gives out the signal for a gentle braking after the short acceleration to allow the vehicle to stop. The importance of the slow braking is to ensure that the frightened driver's over braking is avoided. Figure 4 depicts the front of the car from above. The position of the airbag (item 2) is well visible in the front and the sides of the hood of the vehicle.
The significance of this invention is that according to past experiences, the majority of serious injuries from pedestrian run overs result from the pedestrian's impact with the pavement. This is avoidable with the adoption of this invention.
