Detailed description of the invention
As it is shown in figure 1, the main control unit 2 that the present invention is car body controller 1 connects high-frequency receiver 3, and it is connected tire pressure display 8 with CAN by CAN transceiver 7；High-frequency receiver 3 receives the high-frequency signal of automobile key 4 and tyre pressure sensor 5, thus utilizing existing car body controller 1 to realize the tire pressure monitoring to automobile, improves reliability while reducing integral vehicle cost.
High-frequency receiver 3 is the high-frequency receiver of double modulation mode, and modulation system is amplitude shift keying ASK and frequency shift keying fsk respectively.Main control unit 2 gathers the status signal of ignition switch 6 simultaneously, and when ignition switch 6 is closed, high-frequency receiver 3 is the high-frequency signal RKE that amplitude shift keying ASK pattern receives automobile key 4；When ignition switch 6 starts, high-frequency receiver 3 receives the high-frequency signal TPMS of tyre pressure sensor 5 for frequency shift keying fsk pattern, thus utilizing car body controller 1 not affect its normal function while realizing tire pressure monitoring function.The model of high-frequency receiver 3 is TB31371FNG.
Set of the present invention domestic and international automobile now is nearly all equipped with car body controller 1.Main control unit circuit, radio frequency receiver circuitry, CAN transceiver circuit.Hardware above circuit can share with the main control unit 2 in existing car body controller 1, radio frequency receiver circuitry, CAN transceiver 7 circuit, ensureing on the basis of system reliability, is substantially reduced cost.
Single modulation system high-frequency receiver of former car body controller 1 is changed to double modulation mode high-frequency receiver 3 by the present invention, it is possible to modulation system switched between ASK (amplitude shift keying) and FSK (frequency shift keying) according to instruction.During ASK modulation mode, RKE high-frequency signal can only be received, and under RKE instruction, control the relevant Intelligent key function of car body controller execution, as: open locking etc；During FSK modulation mode, can only receiving tyre pressure sensor high-frequency signal, car body controller is according to relevant informations such as the tyre temperature of sensor detection, pressure, and by analyzing and processing, entering CAN network passes to tire pressure display, carries out relevant display or warning function.
Tire pressure receive capabilities mode of operation in the present invention is:
1, self-inspection:
Car body controller 1 immediately begins to self-inspection after ignition switch opens (IGNON), if TPMS function is opened, lights trouble lamp and carries out self-inspection.Such as system failure, then trouble lamp should extinguish after 3s.
2, park mode (ignition switch IGN_OFF):
This pattern under body controller 1 receives the radiofrequency signal from RKE system.
3, driving mode (ignition switch IGN_ON):
Car body controller 1 receives the radiofrequency signal from TPMS system.If long-time (being defaulted as 10 minutes) does not receive the rf data of any one or multiple tire pressure sensor 5, send sensor failure false alarm.
The present invention has the uninterrupted monitoring function of twenty four hours, is broadly divided into driving mode, low-speed mode, park mode, match pattern.
1, driving mode (speed > 20km/h)
A., under driving mode, when the one or more tire pressure in automobile tire lower than default low pressure alarming value or are higher than the alarm for high voltage value or tire temperature value preset more than setting value, transmitter module launches information, pressure or temperature alarming in 6 seconds.
B. under driving mode, when the one or more tire pressure in automobile tire are with the rate reduction more than 20kPa/20s (rapid air leakage) (and temperature reduction < 10 DEG C), transmitter module launches information, leakage alarm in 6 seconds.
C. under driving mode, there is after alarm condition alert in 6 seconds in sensor, within every 1 second afterwards, send a secondary data (1 package), continue to send about 1 minute (60 times), stop alarm sends state afterwards, transfers to and within every 32 seconds, sends a secondary data by normal condition, if tire condition does not recover, warning message still preserves, until tire recovers normal condition.
D. normal condition (without any alarm condition) tyre pressure sensor 5 detects tire condition for every 4～6 seconds, within every 32 seconds, launches a secondary data.
2, low speed crawl mode (speed≤20km/h)
Tyre pressure sensor 5 judges current vehicle speed according to acceleration transducer, when sensor detects speed less than or equal to 20km/h, (acceleration transducer exists error) thinks that vehicle is in idling or parked state, according to driving mode continuous operation 15 minutes under nominal situation, if speed is again more than 20km/h, time in this process.The time of 15 minutes terminate after sensor enter park mode, and send a data (package).
The same driving mode of other duties of low speed crawl mode.
3, park mode (speed≤20km/h and continue 15 minutes after)
A., under park mode, system is in low work consumption resting state, and tire pressure sensor is timing automatic to be waken up, measures temperature；Pressure；Acceleration；Battery electric quantity；The information such as low-frequency excitation.Corresponding mode of operation is proceeded to according to result.
B. tire condition of tyre pressure sensor 5 timing sampling in every 40 seconds under park mode, sends a secondary data for every 120 seconds to receptor.
C. under park mode, tyre pressure sensor 5 detects abnormal tyre state, within every 1 second, send a secondary data (1 package), continue to send about 1 minute (60 times) data, stop alarm sends shape state afterwards, transfer to and within every 120 seconds, send a secondary data by normal condition, but warning message still preserves, until tire recovers normal condition.
Each tyre pressure sensor 5 has unique ID.Tyre pressure sensor 5 meets trigger condition and enters coupling learning pattern, sends and comprises tyre position information and the data of matching status information, continuously transmits 4 secondary data (interval 100ms) and stop afterwards, and automatically exit from coupling learning pattern.
Above in conjunction with accompanying drawing, the present invention is exemplarily described; the obvious present invention implements and is not subject to the restrictions described above; as long as have employed the various improvement that technical solution of the present invention carries out, or not improved that directly apply to other occasion, all within protection scope of the present invention.
