Vehicle data acquiring and sending device

The utility model relates to a vehicle data acquiring and sending device which is connected with an ECU (engine control unit), an ABS (anti-skid brake system), a speed changing box, an ECAS (electronically controlled air suspension), an instrument, an acceleration sensor, an angle speed sensor, a switching value and vehicle speed pulse signal module and a traveling recorder. The device acquires and sends traveling data to the traveling recorder. The data acquiring and sending device comprises a processor and a communication module, a storage module and a voltage comparator which are connected with the processor, wherein the ECU, the ABS, the speed changing box, the ECAS, the instrument and the traveling recorder are connected with the communication module; the switching value and vehicle speed pulse signal module is connected with the voltage comparator; the acceleration sensor and the angle speed sensor are connected with the processor. Compared with the prior art, the vehicle data acquiring and sending devi
