ON-VEHICLE NAVIGATION EQUIPMENT, ON-VEHICLE DRUNKEN DRIVING DETECTING DEVICE AND METHOD, SAFE DRIVING SERVICE SYSTEM AND METHOD FOR VEHICLE

摘要

An on-vehicle navigation equipment with the function of alcohol detection, an on-vehicle drunken driving detecting device and method, a safe driving service system and method for vehicle are provided. The on-vehicle navigation equipment (100) includes a control module (110), a wireless communication module (120), a locating module (130), an alcohol detecting module (140), a voice module (144), a loudspeaker (150) and a microphone (160), wherein the wireless communication module (120), the locating module (130), the alcohol detecting module (140), the voice module (144) and the microphone (160) are connected with the control module (110) respectively, and the loudspeaker (150) is connected with the voice module (144) and also the control module (110); and the control module (110) receives the detected alcohol concentration information from the alcohol detecting module (140), and compares the alcohol concentration information with a concentration threshold; if the alcohol concentration is above the concentration threshold, the control module (110) will drive the voice module (144) to output a voice signal to the loudspeaker (150), and send an alarm message and the current locating information to a background service center (210). The invention can detect the alcohol concentration in vehicle conveniently in-time so as to send out a promoting message and an alarm message when the alcohol concentration is above the concentration threshold, get safe driving service and reduce the occurrence of traffic accidents.
