The invention relates to a status tracking system for tracking the suspension system in vehicles or the physical condition of the parts in the steering system.
Suspension and various steering parts, such as the wishbone in vehicles, can be deformed and form cracks over time. The estimated life span of these parts is obtained as a result of the tests; however, as a result of various effects, they can be deformed before the estimated time. Recognition of this deformation by the user may occur at further stages of deformation or may not occur at all. Deformations which are not noticed by the user can cause the parts to break down, as well as serious accidents.
Document CN106080072 describes a system in which the tension of such parts is measured by means of a stress sensor and a fault detection is made accordingly. However, it may cause inaccurate damage detection as the part may be subjected to excessive stress in various situations and conditions in which the vehicle operates, even if it is not deformed.
As a result, all the problems mentioned above have made it necessary to make an innovation in the relevant technical field.

The invention is a status tracking system (100) that monitors the condition of the parts (200) in the suspension and steering systems in vehicles. These parts (200) may be parts sensors (200) that are load-bearing or otherwise subjected to force. Cracking may occur in these parts (200) over time, and such cracking may cause accidents. As an example, the said part (200) is a wishbone (suspension fork, suspension triangular arm) in the suspension system in this detailed description of the invention. The invention may also be applied to different parts (200). The vehicles mentioned here are land vehicles such as automobiles, buses, trucks, etc.
With reference to
A processor unit (110) is configured to receive measurements from the sensors in the sensor unit (130). The processor unit (110) may be a microprocessor. The processor unit (110) is associated with a memory unit (120) to read and write data. The processor unit (110) obtains a measurement information about the measurements it receives. The said measurement information may be a converted version of the measurements to a predetermined format. The measurement information may be the deviation (variation) of the measurements taken at a predetermined time interval in this exemplary embodiment.
The memory unit (120) contains reference values comprising measurement values and/or measurement information obtained as a result of the tests, where the parts (200) are tested in a controlled environment with sensors similar to the sensor unit (130). In these tests, the parts (200) are operated under normal operating conditions and measurements are taken, the measurements are taken by applying various effects and forces, and the reactions of the parts (200) are measured under several circumstances. Therefore, the characteristics of the measurements of the parts (200) in normal working, cracked, etc. conditions are determined and the threshold values can be determined according to the measurement values taken from the sensors. For example, the vibration sensor (132) receives vibration measurement having a particular characteristic when it is associated with a cracked part (200).
In the test phase, the damaged, cracked regions of the part (200) when forced are detected as a first region (210). The sensor unit (130) is placed around the mentioned first regions (210).
The processor unit (110) creates a status information by classifying the measurement information according to the reference values in the memory unit (120). The status information may indicate that the part (200) is cracked, that the part (200) is operating under normal conditions, etc.
The status tracking system (100) includes a user interface (161) associated with the processor unit (110). The user interface (161) may be a display connected to the electronic system of the vehicle. The processor unit (110) may also be the electronic control unit of the vehicle. The user interface (161) may be the display of a user terminal (160) in a possible embodiment. The mentioned user terminal (160) may be a mobile phone, tablet computer, etc. The status tracking system (100) may include a first communication unit (151) for enabling communication between the processor unit (110) and the user terminal (160). the mentioned communication unit can communicate preferably with a short distance wireless communication protocol as one of the protocols known in the art for providing wireless data exchange. The status tracking device may also include a second communication unit (152). The second communication unit (152) is configured to connect to a wide area network such as the Internet or to a cellular network. The processor may send measurement information or status information to a server (300) via the second communication unit (152) or the first communication unit (151) and the user terminal (160). Thus, the condition of the parts (200) in the vehicle can be observed remotely, and the measurements taken from the vehicles can be used to update and increase the reference values. The memory unit (120) may be located on the server (300) in a possible embodiment of the invention. In another embodiment of the invention, the server (300) updates the memory unit (120) in the vehicle periodically.
The processor unit (110) may also be associated with a vehicle sensor unit (140). The vehicle sensor unit (140) may include sensors that measure the condition of the vehicle. The vehicle sensor unit (140) may include sensors that measure the starting and stopping of the vehicle, its speed, orientation, the position of the steering wheel, its inclination in relation to the earth, its acceleration, the force of G applied on the same, etc. The sensor unit (130) produces the status information by considering the information it receives from the vehicle sensor as well as the measurement information. For example, the vibration measurements when the vehicle is on a slope are the same, even though the condition of the part (200) may differ according to the vibration measurements taken while the vehicle is driving on a flat road. The unevenness of the road on which the vehicle advances can also be a factor. The processor unit (110) makes the classification by considering this information.
The status tracking system (100) described above operates as follows:
The processor unit (110) receives information about the vehicle being started from the vehicle sensor unit (140) when the vehicle is started. It receives measurements from the sensor unit (130) and obtains measurement information until a predetermined time elapses. It classifies the measurement information according to the reference values in the memory unit (120) after the predetermined time elapses. It creates a status information as a result of the classification and enables it to be displayed on the user interface (161). For example, if the measurement information detects that it exceeds the thresholds in the reference values, it allows a warning to be generated in the user interface (161) to indicate a crack. The mentioned warning may be audible, visual, vibrational, etc. The status information may also be specified in the user interface (161) to indicate the remaining life of the part (200). For example, if the measurements taken are similar to the characteristics of the parts (200) which have been used slightly more than half of their life, as a result of the classification, they can be displayed by determining the percentage of the remaining life.
In a possible embodiment of the invention, the past measurements may be sent to the server (300) or the user interface (161) instantaneously.
The protection scope of the invention is specified in the attached claims and cannot be limited to the account given for exemplary purposes in this detailed description. It is evident that a person skilled in the art may put forth similar embodiments in light of the above described, without drifting apart from the main theme of the invention.
