The invention discloses a high-voltage power supply line maintenance auxiliary pulley which comprises a supporting frame, a second support and a third support, the second support and the third support are arranged on the front portion and the rear portion in parallel, a seat plate is connected to the middle of a supporting plate, the second support is provided with a roller mechanism, triangular wheels provide safety, and then power is provided through a pedal mechanism installed on the first support. According to the high-voltage circuit maintenance device, power is stored in a downhill mode to assist uphill, the device can conveniently move on a cable when a high-voltage circuit is maintained, when the device is used, a constructor can drive the device to move by stepping on a pedal component during maintenance, the physical strength of the constructor is saved, and maintenance operation of the constructor is facilitated.

This disclosure provides a vehicle navigation method, apparatus, electronic device, computer-readable storage medium, and computer program product, relating to the field of computer science, and particularly to the fields of intelligent transportation, autonomous driving, assisted driving, and high-precision map technology. The implementation scheme includes: obtaining the green light end time and remaining distance from the target intersection to which the target vehicle is to pass; determining the estimated target time for the target vehicle to pass through the target intersection; determining a reference green wave speed based on the estimated target time and the remaining distance, the reference green wave speed indicating that the target vehicle can pass through the target intersection before the green light end time at this speed; and generating a target speed curve based on the reference green wave speed to guide the target vehicle to pass through the target intersection at a corresponding speed. The target speed curve characterizes at least one of the deviation between the target vehicle's corresponding speed and the reference green wave speed, the target vehicle's energy consumption, and comfort.

The application discloses a lane line optimization target screening method with state hysteresis, and belongs to the technical field of intelligent driving and vehicle longitudinal control. The method first acquires lane line parameters and vehicle motion parameters through a camera and a vehicle body sensor, calculates a lane center line, a short-time trajectory of the vehicle and a lateral error, and extracts a first derivative of the lane center line; then, a state machine containing six behavior states is used to realize accurate behavior recognition in combination with a lateral error and a first derivative threshold constraint, so that road bending and real lane changing misjudgment are avoided; when the behavior state is switched from lane changing having crossed a line to centering / offset keeping, a preview deviation limiter timer is started, and the sudden change of the preview lateral error is suppressed within a timing window; and finally, a path is screened based on an optimized lane center line fitting, and target screening is completed by adaptively scaling a channel width. The application improves the stability and accuracy of target screening under complex working conditions, reduces unnecessary acceleration and deceleration, and enhances driving comfort and system robustness.
