The application discloses a vehicle maintenance reminder device, which includes a microprocessor, a memory, a gyroscope, A speed pulse module, a power supply module, a display control circuit and a display panel, the microprocessor is connected to the memory, the gyroscope, and the speed pulse module respectively, and the microprocessor is connected to the display panel through the display control circuit. Its disadvantage is that the device uses external equipment to detect the car data, which increases the production cost of the car. In addition, the device can only detect the mileage and driving time of the car, so as to remind the driver to maintain the car. In fact, there are dozens of parameters related to the regular maintenance of the car, so the device cannot effectively remind the driver to maintain the car reasonably.

Utility model content

The utility model mainly solves the problem that the original vehicle maintenance reminder device uses external equipment to detect vehicle data, which increases the production cost of the vehicle, and provides a vehicle maintenance reminder device, which monitors the maintenance item data in real time through the engine electronic control unit , no need for external equipment detection, which reduces the cost of automobile production.

The utility model also solves the problem that the data detected by the original vehicle maintenance reminder device is limited, and there are still problems of untimely and incomplete maintenance, and provides a vehicle maintenance reminder device, which can detect dozens of maintenance items through the engine electronic control unit Data, so that it can timely and effectively remind the driver to carry out reasonable maintenance on the car.

In order to solve the above problems, the utility model adopts the following technical solutions to achieve:

The automobile maintenance reminding device of the utility model comprises a central processing unit and an engine electronic control unit connected with the central processing unit, a signal converter, a display unit and a storage unit, and the engine electronic control unit is connected with the signal converter. In this technical solution, the engine electronic control unit detects the driving mileage and driving time of the car. When the driving mileage or driving time reaches the preset value, the engine electronic control unit sends a signal to trigger the processing program solidified in the central processing unit. The information that needs to be maintained is displayed on the unit to remind the driver to maintain the vehicle. The engine electronic control unit also monitors each engine signal in real time, and performs fault analysis to form a fault code, which is sent to the central processing unit through the signal converter, and the central processing unit compiles and restores the fault code and displays it on the display unit. Fault information is displayed on the display to remind the driver that the vehicle needs to be maintained or repaired.

Preferably, the car maintenance reminding device further includes a touch unit, and the touch unit is connected to the central processing unit. The driver can query the maintenance item data and fault information through the touch unit, and set the maintenance item data parameters.

Preferably, the car maintenance reminding device further includes a voice alarm chip and a loudspeaker, and the voice alarm chip is connected with the central processing unit and the loudspeaker. When the central processing unit sends a maintenance reminder electrical signal to the voice alarm chip, the loudspeaker sends out an alarm sound to attract the attention of the driver.

Preferably, the car maintenance reminding device further includes a navigation device, and the navigation device is connected to the central processing unit. When the display unit prompts that the car needs maintenance or breaks down, the driver can find the nearest service station for maintenance or repair through the information provided by the navigation device.

The beneficial effects of the utility model are as follows: (1) Real-time monitoring of maintenance item data is carried out through the engine electronic control unit without external equipment detection, which reduces the production cost of the automobile. (2) Dozens of maintenance item data can be detected through the engine electronic control unit, so that the driver can be promptly and effectively reminded to maintain the car reasonably.
