The present disclosure relates to an electric drive axle, including a driving assembly, a power coupling gear, a first gear transmission assembly, a second gear transmission assembly and two half shafts connected by a differential, the driving assembly is used to drive the differential. In the above way, the electric drive axle and the electric vehicle realize 3 shifting speeds, and can timely engage in different speeds according to the vehicle load, road conditions, transportation time requirements, etc., so as to realize the efficient operation of the vehicle, improve the operation efficiency, reduce energy consumption, meet the power demand of commercial vehicles with diverse loads and working conditions, and obtain high transportation efficiency and economic benefits.

Electric drive axle and electric vehicle

Aspects of the disclosure provide an apparatus that includes a receiving circuit and a processing circuit. The receiving circuit is configured to receive a satellite signal transmitted from a satellite. The satellite signal carries navigation bits that are transmitted with a navigation bit length. The processing circuit is configured to construct aiding navigation bits based on aiding ephemeris and almanac information that are provided by an aiding source other than the satellite signal. Further, the processing circuit is configured to strip the navigation bits from the satellite signal based on the aiding navigation bits to generate a post-stripping signal, and perform an integration on the post-stripping signal.
