Process.
When receiving coil 3 from the position 3-I along A to when being moved to the position 3-II, see Fig. 4.If without connection 903, this
When Chinese herbaceous peony transmitting coil 703 detect to obtain the induced voltage being gradually increased using the sensor in transmitting converter 901, this
A induced voltage is due to caused by transmitting coil 705 under vehicle, when the transmitting converter 901 that Chinese herbaceous peony transmitting coil 703 is connected
After detecting induced voltage, starts to detect the data such as 703 voltage of Chinese herbaceous peony transmitting coil, electric current, phase and calculate calculating reflection resistance
It is anti-.Judged by the reflected umpedance obtained to detection, if reflected umpedance increases, and is more than certain threshold value, illustrates vehicle 1
Along A to having moved a certain distance, receiving coil 3 has arrived at the surface of Chinese herbaceous peony transmitting coil 703.Such transmitting converter
901 automatically begin to energy transmitting, guarantee that receiving coil 3 being capable of smooth reception energy.901 pairs of transmitting converter detections obtain anti-
It penetrates impedance to be judged, if reflected umpedance does not increase, illustrates that the receiving coil 3 installed on vehicle 1 not yet reaches Chinese herbaceous peony hair
The surface of ray circle 703, continues to standby mode.Above-mentioned control flow is shown in Fig. 7 standby module control flow.
From fig. 4, it can be seen that it is spaced apart on longer charging road, a setting of transmitting module 9 is become into inspection
Module is surveyed, for detecting whether there is vehicle 1 to pass through.By the control strategy point of the wireless energy transmission module 9 in detecting state
For 4 parts.Small-power transmitting is carried out by detection coil 706 using transmitting converter 901, it is weak to generate a lesser alternation
The magnetic line of force 702.The energy of very little can be emitted in this way, the moment has detected whether that vehicle 1 passes through.Using in transmitting converter 901
The data such as the sensor voltage, electric current, the phase that detect calculate reflected umpedance.The reflected umpedance obtained to detection is sentenced
It is disconnected, if reflected umpedance is larger, illustrates that no vehicle 1 passes through, then continue small-power and emit and return.The reflection that detection is obtained
Impedance is judged, if reflected umpedance reduces, and is more than certain threshold value, is illustrated have vehicle 1 by being increased by transmission power, is sent out
The strong magnetic line of force 701 of alternation out.At this moment the transmitting coil 7 of the front and back of detection coil will induce high voltage, then pass through
Impedance judgement, enters emission state by standby mode, sees Fig. 8 detection module control flow.
