Abstract: A vehicle steering control method, device and system, and a vehicle are provided. The vehicle steering control method includes: in a case where a current vehicle speed is less than a turning vehicle speed threshold, steering of a vehicle is controlled by an Electric Power Steering (EPS) to implement cornering of the vehicle; in a case where a cornering condition of the vehicle is not reached during the cornering of the vehicle, the vehicle is controlled by an Electrical Park Brake (EPB) to perform single-side parking to assist in the cornering of the vehicle; and after the single-side parking of the vehicle is implemented, closed-loop control is performed on an electric control booster, the EPB and the EPS, and the vehicle is controlled to turn under the cornering condition.

Abstract: Disclosed are an EPB compatible with an autohold function, a starting method and a vehicle. According to the EPB, during starting, by converting the vehicle from a brake state where the EPB acts into a brake state where an autohold function acts and enabling the vehicle to start from the brake state where the autohold function acts, the vehicle is started stably, the starting noise of the vehicle is reduced and the driving experience is improved.

Abstract: The present invention provide the use of Nicotiana benthamiana (N. benthamiana) HIR3s gene and/or Oryza sativa HIR3 gene in producing plants with resistance to virus and the method for making the plants thereof, the method involve: constructing NbHIR3.1, NbHIR3.2 or OsHIR3 into plant binary expression vector pCV1300 respectively, and introduced into Agrobacterium by electric shock, then transgenic plants overexpressing either NbHIR3.1 or NbHIR3.2 gene or tobacco or rice overexpressing HIR3 were produced by infection with Agrobacterium; the nucleotide sequences of NbHIR3.1, NbHIR3.2 and OsHIR3 are shown as SEQ ID NO:1, SEQ ID NO:2 and SEQ ID NO:23 respectively.
