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.

The disclosure provides a mower and a steering control method thereof. The mower includes a main body, a supporting part, and an operating part. The main body includes at least one driving wheel and a motor and the motor drives the driving wheel to move. The supporting part is connected to the main body for the operator to hold with both hands. The operating part is used to adjust the rotation speed and/or steering of the motor, the operating part is connected to the supporting part, and the operating part is configured to be operated when the operator holds the supporting part.

A steering lever pivot assembly may have a two-axis polymer housing pivotally coupled to a terrain working vehicle at opposing bosses and comprising a pair of reciprocal housing portions, a steering lever pivotally coupled to the two-axis polymer housing, the steering lever having a connecting portion for coupling to a first system of the terrain working vehicle, a clasp coupled to the steering lever and the two-axis polymer housing and having a mounting portion for coupling to a first system of the terrain working vehicle, and a pair of bushings that receive one of the opposing bosses therein. In some aspects, the two-axis polymer housing provides a first axis of rotation at the pivotal coupling between the steering lever and the two-axis polymer housing and a second axis of rotation through the opposing bushings, which may be axially aligned.
