[0002] The power steering and air pump on new energy vehicles can only be driven by electricity, and the control device for electric drive is an auxiliary inverter. Currently, auxiliary inverters commonly used in new energy vehicles include single inverter, two-in-one auxiliary inverter, three The one-in-one auxiliary inverter, four-in-one auxiliary inverter and five-in-one auxiliary inverter are all used to control the auxiliary drive system of new energy vehicles. The auxiliary drive system includes steering drive and pumping drive. There are too many types of motors and air compressors, so that each auxiliary inverter needs to be individually programmed with motor parameters, resulting in too many program version numbers and heavy workload. The motor does not work, and the parameters need to be reprogrammed, which increases the time for on-site debugging and troubleshooting

Embodiment Construction
[0024] The following clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0025] An auxiliary drive configuration system such as figure 1 As shown, it includes a vehicle controller, an auxiliary frequency converter, an auxiliary drive motor and a power battery. The power battery is connected to the auxiliary frequency converter through a high-voltage cable, and a contactor KM 1 with fuse FU 1 , the auxiliary frequency converter is connected to the vehicle controller through the CAN bus and the control hard line. When the CAN bus failure causes the CAN communication to fail, the vehicle controller transmits th...

The invention discloses an auxiliary drive configuration system, which includes a vehicle controller, an auxiliary frequency converter, an auxiliary drive motor and a power battery, the power battery is connected to the auxiliary frequency converter through a high-voltage cable, and the positive connection line between the power battery and the auxiliary frequency converter The cable is equipped with a contactor KM 1 with fuse FU 1 , the auxiliary frequency converter is respectively connected to the vehicle controller through the CAN bus and the control hard line, and the auxiliary frequency converter is connected to the auxiliary drive motor through a three-phase AC circuit. The present invention sorts and sorts all the motor configurations used in the vehicle, and sorts them so that the motor configuration parameters correspond to the motor configuration serial numbers one by one. The vehicle controller can be modified and calibrated, which greatly saves time. At the same time, the version number of the auxiliary inverter program is reduced, which is conducive to after-sales maintenance and debugging.
