This application provides a takeover handling method, device, and equipment for autonomous vehicles, relating to the field of autonomous driving technology. The method includes: acquiring data to be filtered based on the driver's physiological and eye-tracking data within the current time window; filtering and calculating the data to be filtered according to multiple preset data indicators and data types to obtain data to be predicted; obtaining the driver's takeover recovery time based on the data to be predicted using a trained time prediction model; and upon confirmation that a warning time has arrived, acquiring a warning level matching a preset warning execution rule and executing a corresponding takeover request warning strategy to achieve a takeover warning reminder for the vehicle. This application's method obtains more accurate and representative data to be predicted by filtering and calculating physiological and eye-tracking data, obtains a more accurate takeover recovery time using a trained time prediction model, and issues a warning reminder, thereby improving driving safety.

The utility model relates to pen formula injection device technical field, concretely is a kind of dose setting and correction structure and injection device, dose setting and correction structure include: shell and dose setting ring, the double-direction ratchet wheel engagement tooth slot of being provided on the inner wall of shell one end, multiple curved arms are provided on dose setting ring, double-direction ratchet wheel tooth is provided on curved arm;Double-direction ratchet wheel tooth and double-direction ratchet wheel engagement tooth slot engage;When dose setting ring rotates one unit cell in time, double-direction ratchet wheel tooth is separated from current double-direction ratchet wheel engagement tooth slot, enters next double-direction ratchet wheel engagement tooth slot and is engaged, completes the setting of one unit cell dose;When dose setting ring rotates one unit cell in reverse, double-direction ratchet wheel tooth is separated from current double-direction ratchet wheel engagement tooth slot, retreats to last double-direction ratchet wheel engagement tooth slot and is engaged, completes the correction of one unit cell dose.The utility model can realize correction under dose setting error condition, improve injection accuracy, improve the use friendliness of injection device.

The invention discloses a parameter weight determination method and device, equipment, a storage medium and a program product. The method comprises the steps that subjective weights of all factors influencing shale gas productivity are calculated through an analytic hierarchy process; through an XGBoost regression model, the objective weight of each factor influencing the shale gas productivity is obtained through calculation; performing consistency detection on the subjective weight and the objective weight of each factor; and when the consistency detection result is passed, calculating the comprehensive weight of each factor based on the subjective weight and the objective weight of each factor. Through the parameter weight determination method and device, the technical problem that the accuracy of parameter weight determination is low in the prior art is solved.

The invention discloses a control system for a disabled person to control a walking vehicle, and belongs to the technical field of disabled person auxiliary vehicle control. The system comprises a left foot control module, a right foot control module, an electric control system and two driving motors for driving a left wheel and a right wheel respectively. The left foot control module is used for receiving deflection operation applied by the left foot of the user and generating a steering control signal; the right foot control module is used for receiving a pressing operation applied by the right foot of the user and generating a speed control signal or a retreating control signal; the electric control system controls the two driving motors to realize steering at differential speed according to the steering control signal, and controls the rotating speed and steering of the motors according to the speed control signal or the retreating control signal so as to realize advancing, retreating and speed regulation of the vehicle. By means of independent separate control of the two feet, the person with the disabled upper limbs can safely and independently control the vehicle, the problem that the person with the disabled upper limbs cannot use a traditional control device due to the defects of the upper limbs is solved, and the device has the advantages of being easy and convenient to control, safe, reliable and high in adaptability.

The invention relates to the technical field of automobile parts, in particular to an automobile emergency starting power supply with a protective structure, which comprises a power supply body, a female joint is arranged on the power supply body, a male joint is inserted into the female joint, a nut is sleeved on the male joint, a limiting ring is fixedly connected to the tail part of the male joint, and a protective cover is arranged on the limiting ring. A limiting face is arranged on the inner side of the head portion of the nut, an internal thread is arranged on the inner side of the nut, and an external thread matched with the internal thread is arranged on the female connector. A magnetic attraction-torsional spring-tooth meshing composite anti-loosening mechanism is innovatively adopted, intelligent response to a vibration environment is achieved, silence is kept under low-frequency micro-vibration, and fatigue caused by invalid actions is avoided; locking is automatically triggered under high-frequency strong vibration, the connection reliability is reversely enhanced through vibration energy, the limitation of a traditional passive resistance type anti-loosening mode is broken through, and the anti-loosening device is particularly suitable for the specific working conditions of high-frequency electromagnetic vibration and transient torque impact of the electric vehicle.

Hydraulic jacks are widely used in automotive repair and maintenance, equipment lifting, and outdoor emergency situations. Traditional manual push-button jacks are labor-intensive to operate. To address this, the industry has developed several wirelessly controlled electric-driven jack devices. This application integrates the lifting transmission structure and the cam-driven pressure relief structure onto the same reduction output shaft. The forward and reverse rotation of the motor achieves lifting and automatic pressure relief respectively, eliminating the need for additional electronically controlled pressure relief components. The overall structure is more compact and simpler, resulting in lower assembly costs. Furthermore, it eliminates the need for manual operation of the pressure relief valve, allowing operators to work without being close to the load-bearing area, effectively avoiding on-site operational safety hazards.
