Embodiment
Referring to accompanying drawing, the device of the wireless electric energy supplement of tyre pressure sensor, sensing system is divided into the radio energy receiving system of tyre pressure sensor one and is fixed near wheel wireless transmission electrical energy devices, is arranged on the valve cock of wheel rim with the radio energy receiving system of tyre pressure sensor one.The wireless transmission electrical energy devices is controlled by car body controller BCM and is fixed on vehicle body, and the radiating circuit coil is near valve cock.Tyre pressure sensor comprises the circuit such as valve cock, circuit board, wireless receiving coil, high frequency voltage conversion, energy storage pressure stabilizing, rechargeable battery, electric energy detection, charging request, electric energy reception, signals collecting transducer, RF output, wherein wireless receiving coil, high frequency voltage conversion, energy storage pressure stabilizing, rechargeable battery, electric energy detection, charging request, electric energy reception, signals collecting transducer, radio-frequency transmissions circuit are arranged on PCB, PCB is fixed in the valve cock tail end, valve cock front end and rim for automobile wheel are fixed, and provide that tire fills, bleed passage.In order to allow the wireless charging tyre pressure sensor of wheel obtain maximum radio waves, the wireless receiving coil on PCB and the axial keeping parallelism of transmitting coil.
The power supply of generally tyre pressure sensor work comes from the rechargeable battery of internal system.When signal acquisition circuit detects the battery electric quantity deficiency, send to the charging request circuit electric weight request that replenishes.ECU confirms battery electric quantity after receiving the application that replenishes electric weight, detects simultaneously temperature, tire pressure, acceleration parameter in tire.When ECU comparison tire intrinsic parameter, after satisfying the electric energy supplement condition, (in motoring condition, tire pressure, tire, temperature is below alarming value, high frequency voltage conversion, when accumulator is working properly), send charging request signal and short of electricity tire code by the RF circuit to system host BCM, also will work as simultaneously the signal report BCM such as the interior cell voltage of front tyre, temperature, tire pressure, acceleration.After the BCM of system host received information about power and the interior multidate information of tire, BCM controlled wireless launcher and sends interrupted charging measurement pulse 10-30 second to the electric energy receiving system.It is after-applied on battery that the electric energy receiving system converts the charging pulse that receives to charging voltage, observe simultaneously the minor variations of cell voltage, can calculate the parameters such as the efficient of high frequency voltage change-over circuit and the internal resistance of cell and feed back to electric energy transmission device according to dV/dt.BCM according to the electric energy that the tire feedack calculates battery hold time, the electric energy disappearance what etc. factor automatically regulate size and the electric energy transmitting time of the transmitting power of emitter.When the road tire pressure that jolts undesired and stop or due to temperature factor charging conversion efficiency when not high, electric energy transmission device will be avoided this section period and carry out boost charge.The front-end circuit of electric energy receiving system is the LC resonant tank that the wireless receiving coil consists of, and the resonance frequency in LC loop is consistent with the radio wave frequency of emitter.When ECU comparison tire intrinsic parameter satisfies the electric energy supplement condition, rear LC resonant tank starts and prepares reception radio energy signal.The element in the LC loop of wireless receiving coil produces resonance, and circuit two ends after resonance will produce higher high-frequency resonant voltage, this part high frequency voltage is converted to direct voltage and uses super capacitor to carry out energy storage.Meanwhile, electric energy receiving system circuit detects operating state and the energy storage situation of high-frequency conversion circuit.When too low or voltage transitions efficient is too low when the high frequency voltage that receives, the wireless transmission electrical energy devices will stop electric energy supplement, with guarantee the electric energy supplement process effectively and prevent excessive replenishing.
