[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] A new auxiliary drive configuration system, such as figure 1 As shown, it includes the vehicle controller, auxiliary frequency converter, auxiliary drive motor and power battery. The power battery is connected to the auxiliary frequency converter through a high-voltage cable, and contactors are respectively arranged on the positive connection cables of the power battery and the auxiliary frequency converter. KM 1 with fuse FU 1 , the auxiliary frequency converter is connected to the vehicle controller through the CAN bus and the...

The invention discloses a novel assistant driving configuration system. The novel assistant driving configuration system comprises a vehicle controller, an assistant frequency converter, an assistantdriving motor and a power battery. The power battery is connected with the assistant frequency converter by a high voltage cable; a KM1 and a FU1 are correspondingly arranged on the positive pole connecting cables of the power battery and the assistant frequency converter; the assistant frequency converter is connected with the vehicle controller by a CAN bus and a controlling rigid line correspondingly; and the assistant frequency converter is connected with the assistant driving motor by a three-phase alternate current circuit. The novel assistant driving configuration system sorts out all motor configurations used in a vehicle and ranks the motor configurations, so that motor configuration parameters correspond to motor configuration sequence numbers. If the motor needs to be changed, parameters reburning by an assistant frequency converter manufacturer are not necessary, only modifying and demarcating on the vehicle controller are needed, so that time is greatly saved, and meanwhile, reduction of program version numbers of the assistant frequency converter facilitates after-sale maintenance and debugging.
