  • Patent number: 11964709
    Abstract: A steering control device controls a reaction motor that generates a steering reaction force applied to a steering wheel of which power transmission to and from turning wheels is cut off. the steering control device includes: a first processor configured to change a virtual operation range of the steering wheel according to a steering state or a vehicle state by controlling the reaction motor; and a second processor configured to change a degree of change of the virtual operation range of the steering wheel according to the steering state or the vehicle state when an operation position of the steering wheel reaches a position in a vicinity of a limit position of the virtual operation range.

  • Patent number: 11945335
    Abstract: A method and system for characterizing an energy consumption indicator of an electric vehicle (EV) is provided. The method includes performing a cyclic energy consumption test on the EV to acquire a time-speed curve, a time-direct current (DC) energy consumption curve, and a total alternating current (AC) energy consumption in the test cycle. A DC energy consumption rate and an AC energy consumption rate of the EV is determined in each of test sub-cycles. A driving feature is determined in each of the test sub-cycles and a normalized driving feature is determined in each of the test sub-cycles according to the driving feature in each of the test sub-cycles and a base driving feature. A DC energy consumption indicator and an AC energy consumption indicator of the EV are extracted according to DC energy consumption rates, AC energy consumption rates and normalized driving features of the EV in all test sub-cycles.
