Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is the fault diagnosis back-up system synoptic diagram of the utility model motor in electric automobile control system.
Embodiment
As shown in Figure 1, the fault diagnosis back-up system of the utility model motor in electric automobile control system comprises electric machine controller 1, entire car controller 2, motor 3, high-voltage power supply 5 and low-tension supply 4, described electric machine controller 1 is connected by the CAN bus with entire car controller 2, electric machine controller 1 output terminal connects described motor 3 and drive motor 3 operations, described high-voltage power supply 5 and low-tension supply 4 provide described electric machine controller 1 power supply, native system also comprises first memory 6, second memory 7, the 3rd storer 8, wireless transmission/receiver module 9 and remote terminal 10, described first memory 6, second memory 7 is connected described electric machine controller 1 information output respectively with the 3rd storer 8, described electric machine controller 1 is the transmission cycle system's operation information circulation to be stored in the described first memory 6 with 10～200us, with 1～20ms is the transmission cycle system's operation information circulation to be stored in the described second memory 7, with system failure information storage in described the 3rd storer 8, described wireless transmission/receiver module 9 connects described electric machine controllers 1 and with described first memory 6, the information of second memory 7 and the 3rd storer 8 is sent to described remote terminal 10 by telecommunication network, and the information of described remote terminal 10 is sent to described wireless transmission/receiver module 9 by telecommunication network.
Further, above-mentioned first memory 6, second memory 7 and the 3rd storer 8 are power-down data protection FLASH storage chips.
