The invention discloses a multi-frequency antenna system applicable to a mobile terminal with a metal frame structure. The multi-frequency antenna system comprises a metal frame, a PCB and an antenna part. The metal frame is designed to be part of an antenna radiation body, two gaps are formed in the bottom portion of the metal frame, a feeding wiring part and the metal frame together form a T-shaped monopole antenna or an IFA antenna so that the metal frame itself can be used for producing low frequency and high frequency resonance, and other coupling parts can be additionally arranged to be used for adjusting the low frequency and high frequency resonance according to the needs of working frequency bands. The multi-frequency antenna system has the advantages that due to the fact that the gaps of the metal frame are formed in the bottom portion, a user can be prevented from touching the gaps during the actual use process, and the phenomenon that the performance of the antenna is poor when the antenna is held by a hand is avoided; the working frequency bands of the multi-frequency antenna system are 704Mhz-960Mhz and 1710Mhz-2700Mhz, and multi-frequency broadband is realized; compared with a traditional general antenna, the multi-frequency antenna system is multiple in frequency band and broad in frequency width; the antenna structure of the multi-frequency antenna system is small in occupied space, and mutual influence cannot be generated between the antenna structure and surrounding environments.

By means of the vehicle speed guidance and suggestion module, after the entrance of the above vehicle into a guidance range, whether the vehicle is within the range of lane-changing-allowable road segments or not is judged based on the vehicle information within the guidance range and the signal state information of the annunciator. Meanwhile, the vehicle speed guidance and suggestion module provides a vehicle speed guidance suggestion and a driving lane suggestion to the vehicle. The vehicle safety early-warning module calculates a safety margin value between two vehicles according to the information of the vehicle and the information of the preceding vehicle, and then judges the collision risk state of the vehicle according to the safety margin value. According to the invention, the real-time position of the vehicle, the real-time speed of the vehicle and the mutual influence among vehicles are fully contemplated. In this way, when the vehicle passes through a signalized intersection, the stop delay of the vehicle is reduced. Therefore, the traffic efficiency of roads is improved and the environmental pollution is reduced.
