Recently, Mao Ge encountered a particularly annoying thing. The car she just bought always had to refuel, because it was an old car with no fuel consumption display. The daughter-in-law wondered if Mao Ge had borrowed the money to make a small vault in the name of refueling. After being twisted twice, Mao Ge felt that it was really unfair, so she found an artifact called on-board OBD on the Internet, which not only can display the fuel consumption and calculated expenses, but also has many practical functions.
What is on-board OBD?
OBD, also called on-board diagnosis system, was originally designed as a professional instrument for detecting faults and exhaust emissions. With the development of science and technology, it has been widely used by ordinary car owners. Just plug the wireless adapter into the OBD interface, you can automatically read the data, connect the mobile phone through Bluetooth, and open the mobile APP to view the data. In addition to fuel consumption display, there are real-time driving data display, cost analysis, fault detection and maintenance reminder, etc., which is very suitable for Mao Ge.
Real-time driving information display
Just start it, and the adapter will automatically connect with the phone. Through the mobile APP, you can see real-time data such as fuel consumption, speed, water temperature and vehicle speed, all of which are digital real-time display, which is very convenient to read. In addition, there is a voice broadcast function, so that the owner can master the driving situation of the vehicle at all times.
Automatic calculation of fuel consumption cost
In addition to the above functions, the on-board OBD also has an intelligent locator, which can record the vehicle’s driving trajectory. At the same time, the new sensing function can monitor the dynamics of the vehicle during driving, such as when the fuel consumption is the lowest or highest, and when there is a sudden brake, etc., which will be recorded and summarized.
In addition, Mao Ge thinks that everyone is most concerned about the fuel consumption, and the mobile APP will automatically calculate the cost according to the pre-input and the average fuel consumption each time. If you are still using the fuel consumption of 100 kilometers displayed in the car to convert the cost yourself, it is really "out of date", which is not only untimely but also troublesome.
fault detect
Although today’s vehicles have the functions of self-test and fault light prompt, what fault each fault light represents may not be known by every owner. On-board OBD can not only detect automatically, but also directly display what faults have occurred. In this way, the owner can call the technical maintenance master in time to ask if the vehicle can still run normally or how to deal with it according to the suggested fault.
Maintenance reminder and project recommendation
The maintenance reminder on the car OBD, Mao Ge felt another good function. Many car owners don’t know the maintenance time and items of their vehicles. After the car OBD sets up the model on the mobile APP, the software will automatically calculate the mileage and time of the next maintenance according to the usage of the vehicle, and recommend the maintenance items, which is very worry-free.
This time, Mao Ge experienced only the basic version of OBD, which was not the most complete, and the adapter would be disconnected from the mobile phone after leaving the vehicle. The high-end version of the product can be connected to the network after being put into the mobile phone card, and the owner can remotely monitor the vehicle with the help of cloud technology, which has more comprehensive functions such as anti-theft positioning, remote detection, electronic dog and so on, but the relative price will be a little more expensive.
