Smart onboard system

The invention discloses a smart onboard system which is characterized in that the smart onboard system includes a wireless communication module, a GPS module, a driving data acquiring module, a calibration module, a smart household control module and a processor. The GPS module acquires a user's current position and map road conditions, calculates predicted time for going through each road section and predicted time for arriving at home. The driving data acquiring module, through a CAN total interface line, acquires real-time vehicle velocity, and obtains actual time for going through the current road section. The calibration module conducts ratio calculation on the actual time for going through the current road section and the predicted time for going through the current section, and obtains a difference coefficient P. The processor receives the predicted time for arriving at home from the GPS module and P value from the driving data acquiring module, and calculates the predicted time for arriving at home after calibration, and again in accordance with the smart household working hours given by the smart household control module, compares the smart household working hours with the predicted time for arriving at home after calibration, and sends a household control instruction through the wireless communication module based on the comparison result, and gives feedback through the wireless communication module.
