This invention relates to a control device for a wing sail of an unmanned surface vessel (USV), comprising a structural component, an adjustment component, and a rotational speed monitoring mechanism. The structural component includes a frame assembly and a wing sail. The wing sail is disposed on one side of the frame assembly, and the adjustment component is disposed inside the frame. The adjustment component is connected to the rotational speed monitoring mechanism and can adjust the orientation of the wing sail. The adjustment component includes a position control element, a clutch mechanism, and a locking mechanism. The position control element controls the states of the clutch mechanism and the locking mechanism. By utilizing external airflow as the driving force for wing sail steering, no additional power input is required. The adjustment and locking / unlocking control of the wing sail orientation are achieved only through low-power control components, thereby reducing the energy consumption of the USV and improving the convenience of steering control.

The invention belongs to the technical field of automobile steering control, and provides a vehicle pivot steering control method and system and application, and the method comprises the following steps: in response to a pivot steering instruction, judging whether a vehicle meets a pivot steering condition or not; if yes, an electric differential steering strategy is executed, and the electric differential steering strategy comprises the steps that reference torque needed for driving is calculated based on the dynamically-determined target wheel speed, and when the reference torque is within the allowable torque range, the rotating speed of rear wheels of the vehicle is controlled to be larger than the rotating speed of front wheels, and the rotating directions of the rear wheels are opposite to those of the front wheels; and if the pivot steering condition is not met or the reference torque exceeds the allowable torque range, a mechanical auxiliary strategy is executed, and vehicle body steering is achieved by driving an auxiliary steering mechanism of the vehicle. In-situ steering of the vehicle can be quickly completed, so that the problem of difficulty in passing due to incapability of turning around in situ is effectively solved.

The utility model provides a crawler steering system which comprises a steering gear arranged on a frame, a first reversing valve, a second reversing valve, a first hydraulic motor connected with the first reversing valve and a second hydraulic motor connected with the second reversing valve, the first reversing valve and the second reversing valve are connected with the two ends of the steering gear respectively, and a third reversing valve is arranged on the frame. The third reversing valve is respectively connected with the first reversing valve and the second reversing valve, the third reversing valve is connected with an oil pump, the steering gear is connected with a steering wheel through a steering shaft, and output ends of the first hydraulic motor and the second hydraulic motor are respectively connected with driving wheels. According to the crawler steering system, the crawler is driven to advance, stop or retreat through operation of the third reversing valve, the effect of controlling the rotating direction of the driving shafts in the first hydraulic motor and the second hydraulic motor is achieved through rotation of the steering gear, reverse rotation of the two driving wheels is achieved, and therefore advancing and steering of the crawler are achieved. The crawler is simple and convenient to steer, smaller in steering radius and higher in steering efficiency.
