Abstract
The present invention discloses a vehicle radio communication system based on frequency hopping communication, comprising a RKE key, a TPMS sensor and a central receiving device, wherein the RKE key and the TPMS sensor respectively communicate with the central receiving device via different frequency points; the central receiving device is connected to an anti-theft device and an instrument panel of a vehicle. The present invention further discloses a vehicle radio communication method based on frequency hopping communication realized by the system, wherein the central receiving device circularly scans the frequency points for communication of the RKE key and the TPMS sensor; if a frequency point receives an effective signal, the central receiving device suspends the scanning, and fixedly works on the frequency point to communicate with the RKE key or the TPMS sensor. In the present invention, a central receiving device is used for scanning different frequency points, and a remote keyless entry system and a tire pressure monitoring system are integrated, so that the cost of the vehicle is reduced greatly.

The invention also discloses a kind of automobile wireless communication means that adopts said system to realize based on frequency hopping communication, described central receiving device carries out scan round for the frequency of RKE key and TPMS sensor communication, if there is which frequency to receive the actv. signal, then central receiving device suspends scan round, and steady job communicates with RKE key or TPMS sensor on this frequency, behind this time sign off, described central receiving device is proceeded scan round.
When described central receiving device carried out scan round, the cycle of each frequency point scanning was 20ms.
As one embodiment of the present of invention, as shown in Figure 2, following steps are carried out in circulation successively:
The first step: regulate the inner tuning capacity of acceptor circuit, make central receiving device be operated on the frequency of RKE key continuous detecting 20ms;
Second step: judge whether to receive RKE key signal,, carried out for the 3rd step if receive RKE key signal; As do not have, jumped to for the 4th step;
The 3rd step: continue to receive the useful signal of RKE key, up to receiving;
The 4th step: change the inner tuning capacity of acceptor circuit, make circuit working on the TPMS frequency;
The 5th step: judge whether to receive the TPMS signal,, carried out for the 6th step if receive the TPMS signal; As do not have, jump to the first step;
The 6th step: continue to receive the useful signal of TPMS,, jump to the first step up to receiving.
In sum, the present invention scans different frequencies by adopting a central receiving device, and simultaneously integrated remote keyless enters system and tire pressure monitoring system, reduces the cost of automobile greatly.
