Abstract

The invention discloses a vehicle reminding control device and method based on an OBD-II port. The device comprises a processor which is connected with a GPRS wireless communication module and a GPS positioning module, the processor is further connected with an ECU inside a vehicle, and a backup power source is further arranged in the processor. A battery voltage pin of the OBD-II port is connected with a power supply pin of the processor, and the processor is connected with a first diagnosis line of the OBD-II port and a second diagnosis line of the OBD-II port. In addition, a data line of the OBD-II port is connected with a third I / O port of the processor, and the GPRS wireless communication module is connected with a monitor terminal through a communication network. By the adoption of the control method, the defects that when a fuel cut-off and power failure mode is used for processing, the complicated circuit technology of a relay needs to be combined, rewiring needs to be conducted inside the vehicle frequently, so that the mode is troublesome, and faults can be caused easily in the prior art are overcome.

Description

technical field [0001] The invention belongs to the technical field of reminder control for vehicles, and in particular relates to a reminder control device and control method for vehicles based on an OBD-II interface. Background technique [0002] After buying a new car, the payment is often postponed for various reasons, so when the critical time comes, it is often impossible to take real-time and effective measures to remind and control, although there is a way to deal with it by cutting off the oil and power at that time , but this complex circuit technology combined with relays often needs to be rewired in the car, which is very troublesome and prone to failure, and the external circuit structure is often more easily shielded by signal shielding technology, resulting in inability to effectively remind and control. One thing is that different models often have different protection systems. Once an external force destroys the existing circuit system, the car's starting d...
