Abstract

The invention provides an intra-car air environment information acquisition control system and method based on on-board diagnostics (OBD). The system comprises a CAN transceiver module, an OBD master control analysis module, a gas detection module, a temperature sensor, a Bluetooth module and a wireless security control module. The wireless security control module comprises a wireless transmitter and further comprises a wireless receiver, a motor controller, a car window motor and a car window lifting device which are installed in a car door. The gas detection module and the temperature sensor detect the harmful gas content and the intra-car temperature, and convert data and send the data to the OBD master control analysis module, and the OBD master control analysis module compares the data with standard values. When one or more data are not within a standard value range, a car window is opened, and meanwhile the gas data and the temperature data are sent to a mobile phone of a driver so as to remind the driver. According to the intra-car air environment information acquisition control system and method based on OBD, the OBD function of a car is effectively used, the intra-car air environment is kept within the standard value range, the function of notifying and reminding the driver is achieved, and the effect is good.

Description

technical field

[0001] The invention belongs to the field of vehicle control and diagnosis equipment, and relates to an OBD-based air environment information collection and control system in a car and a collection and control method. Background technique

[0002] OBD is the abbreviation of On-BoardDiagnostics (on-board diagnostics system). It is a diagnostic system integrated in the engine management system to monitor the working status of exhaust emission components. The OBD system improves engine efficiency and reduces Air pollution from vehicle exhaust. Every car that meets emission standards has an OBD interface, which is called a universal standard diagnostic test connector, or DLC for short. The DLC has a 16-pin plug that provides power to devices on that connector; the standard installation location for the DLC is under the driver's side dash.

[0003] With the continuous increase of people's time in the car, the air quality problem in the car has been paid more and...
