  • Publication number: 20230286347
    Abstract: Disclosed in the present invention are an inertial regulation method of active suspensions based on terrain ahead of a vehicle and a control system thereof. According to the scanned terrain ahead of the vehicle, a center of mass trajectory and attitude history are calculated when the vehicle passes through the terrain ahead of the vehicle with passive suspensions. After smoothing the trajectory, the active suspension is controlled to make the vehicle drives according to the smoothed trajectory. During this period, a smoothness coefficient is adjusted to make each suspension stroke be limited within a limit stroke, and according to the supporting force and stroke of each active suspension calculated from a dynamics model, the impedance control based on force-displacement is carried out on an actuator of the suspension. The present invention can significantly improve the driving comfort and handling stability of the vehicle driving on an uneven road surface.

  • Publication number: 20230286345
    Abstract: An inertial regulation method and control system of vehicle active suspension based on a supporting force of each wheel comprises an inner loop control and an outer loop control. The inner loop control is to calculate, according to the dynamics, a theoretical supporting force of each wheel when the vehicle is driving on a virtual slope plane with a 6-dimensional acceleration and a pitch angle measured by an inertial measurement unit; compare the theoretical supporting force with the measured supporting force of each wheel; and control the expansion of each suspension cylinder according to the difference value, so that the supporting force of each wheel changes according to the theoretical supporting force. The outer loop control is to control each suspension cylinder for the same expansion of displacement, so that the average value of all the suspension cylinder strokes tends to a median value.

  • Publication number: 20230062272
    Abstract: Provided are compositions for simultaneously modifying amino acids of site 736 and site 738 of pAPN gene and application thereof. An sgRNA set specifically recognizing porcine pAPN gene can recognize sequences near amino acids of site 736 and site 738 of pAPN gene, and has strong specificity. On this basis, in combination with a composition consisting of a cleavage protein and a double-stranded donor sequence, simultaneous modification of amino acids of site 736 and site 738 of the pAPN gene can be realized. Under editing of the composition, the amino acids of site 736 and site 738 of the pAPN gene are modified precisely and effectively, which can prevent normal expression of other amino acids of the pAPN gene from being damaged or changed. Therefore, it can resist TGEV infection, and also can retain the physiological activity function of the pAPN protein to the maximum extent.

  • Patent number: 11575093
    Abstract: A method for enhancing the performance of pentacene organic field-effect transistor (OFET) using n-type semiconductor interlayer: an n-type semiconductor thin film was set between the insulating layer and the polymer electret in the OFET with the structure of gate-electrode/insulating layer/polymer/pentacene/source (drain) electrode. The thickness of n-type semiconductor layer is 1˜200 nm. The induced electrons at the interface of n-type semiconductor and polymer electret lead to the reduction of the height of the hole-barrier formed at the interface of polymer and pentacene, thus effectively reducing the programming/erasing (P/E) gate voltages of pentacene OFET, adjusting the height of hole barrier at the interface of polymer and pentacene to a reasonable scope by controlling the quantity of induced electrons in n-type semiconductor layer, thus improving the performance of pentacene OFET, such as the P/E speeds, P/E endurance and retention characteristics.
