Vehicle data collecting and transmitting device

Abstract

The invention relates to a vehicle data collecting and transmitting device. The device is in connection with a vehicle engine ECU (electronic control unit), an ABS (anti-lock brake system), a gearbox, an ECAS (electronically controlled air suspension system), an instrument, an acceleration sensor, an angular velocity sensor, a switching quantity and vehicle speed pulse signal module, and a driving recorder. After collecting driving data, the device transmits it to the driving recorder. The data collecting and transmitting device comprises a processor, and a communication module, a memory module and a voltage comparator that are connected to the processor. The engine ECU, the ABS, the gearbox, the ECAS, the instrument and the driving recorder are connected to the communication module. The switching quantity and vehicle speed pulse signal module is connected to the voltage comparator, and the acceleration sensor and the angular velocity sensor are in connection with the processor. Compared with the prior art, the device provided in the invention enables the vehicle driving recorder to realize collection of vehicle oil consumption, driver's driving behavior, vehicle running state and other data. Thus, the vehicle data collecting and transmitting device can be a new initiative for installation of an intelligent security guidance monitoring recorder on a motor vehicle.

Description

technical field [0001] The invention relates to a driving data processing device, in particular to a vehicle data collection and transmission device. Background technique [0002] Car driving recorder, the promotion of traffic safety and its function in traffic management, has been widely recognized by traffic management personnel at all levels in my country. Therefore, in recent years, efforts have been made to promote the use of driving recorder in traffic management. The national standard GB / T19056-2003 "Car Driving Recorder" was issued on April 15, 2003, and was implemented on September 1, 2003. my country's "Road Traffic Safety" Law came into effect on May 1, 2004, which stipulates that passenger vehicles, heavy-duty trucks, and semi-trailer tractors used for highway operations should be installed and used with vehicle driving records that meet national standards. instrument. It can be said that the car tachograph has been widely used, but the existing car tachograph c...

Problems solved by technology

It can be said that car driving recorders have been widely used, but the existing car driving recorders can only collect data information such as speed changes, brake lights, direction lights, headlights, wipers, and car doors per second, and the collected data is very little. , cannot meet the user's demand for data such as fuel consumption, driving behavior, and vehicle operating status. Driving level, reduce vehicle traffic accident rate

Due to the collection of fuel consumption data, the judgment of driver's driving behavior, and the collection of vehicle running status, it involves the vehicle engine ECU (electronic control unit), gearbox, ABS (anti-lock braking system), ECAS (electronically controlled air suspension system) Such as the reading of CAN (controller area network) data and the data analysis of acceleration sensors and angular velocity sensors. These data are generally controlled by vehicle manufacturers, and general car travel recorder manufacturers cannot obtain these data.
