System for for detection of vehicle body damageThe present invention is related to a system for detection of vehicle body damage, according to the preamble of claim 1.BackgroundVehicles that goes in a route or are involved in a rental-pool (buses), has claim on repair visible damages within reasonable time. If exposed to frequent damages this will result in big workshop bills. One way to reduce these workshop bills is to make the drivers pay more attention to driving which would result in that the amount of damage is reduced.From US5959365A it is known an apparatus to provide a monitoring device for detecting problems associated with the wheels of trucks and trailers. The apparatus comprises one or more individual axle spindle sensors, a programmable microprocessor for receiving and processing the sensor signals to detect an alarm condition and alarm means to alert the driver of a problem with one or more of the wheels.In DE3937403 A1 it is disclosed a method of monitoring the functionality of vehicle chassis during travel involving the use of vibration detectors whose output signals are processed in a microcomputer and fed to a display. The vibration in each wheel's suspension is measured in the X and Y directions in at least two mutually inclined planes. The output signals are processed and evaluated by the microcomputer with the associated speed signals in digitised form. Especially suitable for monitoring tyre pressure, wheel imbalance and shock absorber state. Noise factors are eliminated to enable improved functionality monitoring during travel.From CN103223921 it is known a vehicle monitor system based on Internet of Things, which comprises a vibration sensor, a vehicle monitor device, a control module, a memory module, a CDMA (Code Division Multiple Access) wireless transmission module, and a mobile phone terminal, wherein the control module is connected with the vibration sensor, the vehicle monitor device, the CDMA wireless transmission module and the memory module respectively; and the CDMA wireless transmission module is further connected with the mobile phone terminal. The system utilizes the Internet to enable a vehicle owner to find out unusual conditions of the vehicle, and master evidences timely. US2016144817 describes systems, software, sensors, and applied solutions for detecting incidents associated with a vehicle, where sensors associated with the vehicle identify impacts or proximity alerts to other vehicles and objects and record information related to those detected incidents. The recorded information can be communicated immediately to interested parties of the person or entity (e.g., emergency responders, business contacts) associated with the vehicle, or alternatively, stored for inspection at the vehicle and reviewed at a destination along the vehicle's route. In one example method, operations include detecting an incident associated with a monitored vehicle, where detecting the incident comprises receiving an alert from at least one sensor associated with the vehicle, identifying a location of the vehicle in response to the detection, and storing a record of the detected incident, where the record includes the identified location of the vehicle and a time associated with the detected incident.In WO2017135825 is described a device, method and system for external chassis damage detection. The sensor device comprises at least one sensor for sensing behaviour patterns in a chassis part of a vehicle, a CPU module connected to an output of the sensor for analysing the behaviour patterns sensed by the sensor, and communication module connected to the CPU module for communicating analysed vibration pattern to a remote receiver. It is described that there are set limits for the sensitivity level such that the sensor device will ignore sound and vibration originating from normal operation of the vehicle. This will not provide any additional information about a possible damage, but will contribute to reducing the amount of data that will have to be processed due to limiting the number of detections.The prior art solutions are accordingly related to alarm transactions to emergency, and others via mobile telephone, sign up for service. Prior art describes the use of vibration sensors, proximity sensors, collisions, lateral against doors, theft alarm, as well as sensors for monitoring tires according to air pressure, problems with wheels, shafts, etc. It is also known the use of systems using GPS and time for logging information, as well as arranged for saving and reporting damages.However the prior art solutions are not capable of registering events automatically on-line.The prior art solutions further suffer from not being capable of ensuring that innocent drivers are not wrongly tied to damages.Prior art solutions further suffer from that they do not provide a solution to aware the drivers to reduce the amount of damage and encouraging the drivers to change driving behaviour. The prior art solutions further suffer from that they are not capable of detecting so-called scratching damages, and is further not arranged to provide information of direction of vehicle in relation to obstacles the vehicle is in contact with.Prior art solutions further suffer from that they cannot report damages directly to a vehicle service workshop.ObjectThe main object of the present invention is to provide a system for detection of vehicle body damage partly or entirely solving the lacks of prior art.It is further an object of the present invention to provide a system capable of registering events automatically, in real-time, on-line.An object of the present invention is to provide a system ensuring that innocent drivers are not wrongly tied to damage.It is an object of the present invention to provide a system capable to aware drivers of vehicles to reduce the amount of damage by encouraging the drivers to change driving behaviour.An object of the present invention is to provide a system arranged for filtering data and provided with a machine learning system that filter out sensor records having suspicious values.It is an object of the present invention to provide a system capable of detecting location of a body damage along a side of the vehicle.An object of the present invention is to provide a system capable of connecting time and location of a damage to be able to inform drivers of potential problem areas during driving, such as e.g. narrow streets, turnarounds, garages or depot.It is an object of the present invention to provide a system capable of reporting damages directly to a vehicle service workshop.Further objects of the present invention will appear from the following description, claims and attached drawings.
