Abstract: A hydro-mechanical transmission device with a dual-clutch transmission includes an input mechanism, a pump-controlled motor mechanism, an odd-numbered gear transmission mechanism, an even-numbered gear transmission mechanism, an output mechanism, and a jackshaft. The input mechanism is connected to the odd-numbered gear transmission mechanism and the even-numbered gear transmission mechanism that are connected in parallel, and is connected to an input end of the pump-controlled motor mechanism. An output end of the pump-controlled motor mechanism is connected, through the jackshaft, to the odd-numbered gear transmission mechanism and the even-numbered gear transmission mechanism that are connected in parallel, and is connected to the output mechanism. Switching among hydraulic transmission, hydro-mechanical transmission, and mechanical transmission modes between the input mechanism and the output mechanism is implemented by controlling combination and engagement/disengagement of clutches and a brake.

Abstract: Provided is an intelligent vehicle safety driving envelope reconstruction method on the basis of integrated spatial and dynamic characteristics. Starting from simulating an actual driver's estimation of potential collision risks in the forward driving area, a prediction result of a front vehicle driving behavior is introduced to an environment perception link of the intelligent vehicle; on the basis of the prediction result of the front vehicle driving behavior, a safety driving envelope of the intelligent vehicle is reconstructed by integrating spatial and dynamic characteristics (a safety environment envelope reconstruction and a stable control envelope reconstruction), so as to improve the safety and stability of intelligent vehicle. First, based on the prediction of the front vehicle driving behavior, a lateral and a longitudinal distance between the intelligent vehicle and the front vehicle are corrected, to realize the envelop reconstruction of the safety environment of the intelligent vehicle and to improve the safety of intelligent vehicle. Then, on the basis of the reconstructed safety environment envelope and an dynamical model of the intelligent vehicle, the stable control envelope of the intelligent vehicle is reconstructed, so as to improve the stability of the intelligent vehicle.

Abstract: The present invention belongs to the field of machine vision. A saliency-based method for extracting a road target from a night vision infrared image is disclosed. The method combines saliencies of the time domain and the frequency domain, global contrast and local contrast, and low level features and high level features, and energy radiation is also considered to be a saliency factor; thus, the object of processing is an infrared image and not the usual natural image. The extraction of a salient region is performed on the raw natural image on the basis of energy radiation, and the obtained extraction result if the salient region is more accurate and thorough, and the contour of a target in the salient region is clearer.

Abstract: The invention proposes a fault-tolerant field-oriented control method of five-phase interior permanent-magnet fault-tolerant linear motor (IPM-FTLM) with two nonadjacent short-circuit phase faults. Firstly, the extended Clark transformation matrix can be obtained according to the principle that magnetic motive force (MMF) keeps constant before and after the two-phase open-circuit faults, the constraint that the sum of healthy phase currents is zero and the adjacent two-phase current amplitude is equal. The back electric motive force (EMF) can be estimated by the transposed matrix. The nonlinear strong coupling system becomes the first-order inertia system when using the internal mode controller, the first-order inertia feed-forward voltage compensator and back-EMF observer, as the motor is with fault. Then, according to the principle that the sum of MMF of the healthy phase short-circuit compensation currents and two phases short-circuit fault currents is zero, the short-circuit compensation voltage can be obtained, and then these voltages add vector-controller output voltages, respectively. The invention not only restrains the thrust force fluctuation caused by two nonadjacent short-circuit phase faults, but also more importantly keeps the same dynamic and steady performance as the normal conditions, and also it has the constant switching frequency of voltage source inverter.

Abstract: A hybrid transmission device with a mechanical continuously variable transmission and a control method thereof are provided. The device includes an input shaft assembly, a front planetary gear transmission assembly, a rear planetary gear transmission assembly, an output shaft, and a mechanical continuously variable transmission. Single transmission modes and hybrid transmission modes are implemented through combination and engagement/disengagement of brakes and clutches. The device and the method realize free switching among various transmission modes and integrates the single transmission modes and the hybrid transmission modes, thereby increasing the degree of freedom in adjustment and expanding the speed regulation range. Input and output shafts of a front cup wheel and ring disc transmission mechanism and a rear cup wheel and ring disc transmission mechanism are coaxial, so that the structure is compact and intermediate rollers can stably and reliably transmit large torque.
