The invention provides a hybrid electric vehicle and a control method thereof, and is mainly used for start control of an engine. A first rotating speed and a second rotating speed are set and the engine is controlled to inject oil or not to inject oil according to the two rotating speeds, the start control method of the engine in a hybrid power system is optimized, misoperation of a driver is reduced, and the reliability of a BSG (Belt Starter and Generator) / ISG (Integrated Starter and Generator) motor to start the engine is improved.

The invention relates to a parametrization design method of an anti-disturbance composite servo controller. The parametrization design method is that damp of a closed loop system pole is dynamically changed to synthesize the quick response performance of a low-damp system and a low-overshoot characteristic of a high-damp system, accordingly quick and stable fixed-point tracking is achieved. The controller consists of a conventional linear feedback control law serving as a first portion and used for ensuring the system stability so as to enable a closed loop system to have high response speed, a non-linear feedback control law serving as a second portion and used for enabling a controlled system to quickly and stably track a set point, and a third portion for merging disturbance and uncertainty factors of the system to form an extension state variable and meanwhile estimating a non-measurement state and unknown disturbance of the system through a reduced order extension state observer and used for state feedback and disturbance compensation. By adopting the method, quick, stable and accurate servo tracking of a target position under various load conditions is achieved.

The invention discloses an auxiliary tool for enabling an all-in-one power machine to enter a compartment. The auxiliary tool for enabling the all-in-one power machine to enter the compartment belongs to the technical field of electric drive tracked vehicles, and can enable the all-in-one power machine to quickly and accurately enter the compartment. The tool comprises a base body (1), a buffer rubber block (5), a fine-adjustment nut (6) and a guide plate (7). The base body (1) is provided with a central hole for installing the guide plate (7), and three pin cylinders installed with limiting plugs, pressure springs and locating pins. An optical shaft with a screw thread on the end head, and three blind holes for limiting the locating pins (4) are formed in the center of the guide plate (7). The upper side of the guide plate (7) is bent, and the buffer rubber block (5) is adhered onto the bending plate. According to the auxiliary tool for enabling the all-in-one power machine to enter the compartment provided by the invention, the buffer rubber block and the locating pins with elasticity functions are adopted in a support structure, so that the impact on the auxiliary tool when the all-in-one power machine enters the compartment is reduced, the stability in entering the all-in-one power machine into the compartment is ensured, an axial distance fine-adjustment function is realized, and an entering position can be accurately located conveniently.

The invention provides an optical measurement method for long-distance running, the method comprising: athletes wear reflective signs; a modulated light source and an image capture device are installed at the physical end point of the track; Shooting images continuously towards the physical end point under the light of the second intensity, further comprising the steps of: acquiring a bright frame image taken by the image capturing device under the light of the first intensity; Frame image; differentially process the bright frame image and the dark frame image to obtain a differential image; detect whether a logo appears in the differential image, if so, identify the identity of the athlete through the logo, and mark the frame where the logo appears. The invention also provides a corresponding optical measurement system. Compared with other photographic identification methods, the present invention has beneficial effects such as strong resistance to ambient light interference, low identification cost, high accuracy, and easy operation.

The present invention relates to an anti-skid device for auxiliary emergency braking, and specifically to an anti-skid emergency device for vehicles in snow days. The device is fixedly mounted on a fender liner above a wheel, and comprises an actuator, an electronic control system and an anti-skid pad. The anti-skid pad is fixed in the actuator; the electronic control system is electrically connected with the actuator; The anti-skid pad comprises a stainless steel upper surface layer, a carbon steel layer and a rubber lower surface layer; the stainless steel upper surface layer is welded with the carbon steel layer; the carbon steel layer is bonded with the rubber lower surface layer; four corners and the center of each of the stainless steel upper surface layer, the carbon steel layer and the rubber lower surface layer are further fixed by rivets; the stainless steel surface layer is in contact with the tire; the rubber lower surface layer is in contact with the ground and inlaid with nails. The anti-skid emergency device for vehicles in snow days provided by the invention is simple in structure, uses the anti-skid pad to generate resistance, so that the vehicle produces greater resistance during emergency braking, and does not influence the requirements of small resistance of the vehicle while driving, and greatly reduces car accident in snow days.

The invention discloses a rail sliding type arc extinguisher. The rail sliding type arc extinguisher comprises a magazine (1) and an arc extinguishing cylinder (6), wherein a triggering coil (3) and an arc guide fitting (9) are arranged inside the magazine (1); an arc guide electrode (8) connected with the arc guide fitting (9) and a gas pill triggering position are arranged at the bottom of the magazine (1); a side surface electrode (5) is arranged on the sidewall of the gas pill triggering position, wherein a spiral suspended rail (2) from top to bottom for bearing an arc extinguishing gas pill (4) is arranged on the inner wall of the magazine (1), and a groove matched with the spiral suspended rail (2) is formed in the surface of the arc extinguishing gas pill (4) which is mounted inside the magazine (1). The rail sliding type arc extinguisher is simple in structure, safe and reliable; the arc extinguishing gas pill inside the magazine is capable of sliding down smoothly only under the action of the gravity, and therefore, the step of pill changing after once triggered arc extinguishment is realized.
