Abstract: The present invention provides a method for preparing a thermoplastic elastomer with excellent resilience and high strength, comprising the steps of: A) adding at least two soft segment monomers into a solvent, and then adding a hard segment monomer to the mixture for reaction under the action of a catalyst to obtain an initial reactant; B) subjecting the initial reactant to react with a chain extending agent to obtain a thermoplastic elastomer. In the thermoplastic elastomer provided by the present application, the multiple hydrogen bonds in the hard segment monomer provide it with high strength and high modulus, and the thermodynamic incompatibility of the soft segment monomers provides it with excellent toughness and high resilience. Therefore, the thermoplastic elastomer provided by the present application has advantages of excellent strength, toughness, rapid resilience and high resilience rate.

Abstract: The present disclosure belongs to the technical field of catalyst preparation, and provides a polynorbornene/carbon black-cross-linked three-dimensional network-immobilized bimetallic copper/gold (PNBI/CB-Cu/Au) nanocatalyst, and a preparation method and use thereof. Metallic copper and gold both exist in a form of nanoparticles in the catalyst and are uniformly dispersed, and further enhancing a catalytic performance. Moreover, the carrier is a polynorbornene/carbon black-cross-linked three-dimensional network, and a relative content of free hydroxyl groups in the catalyst is controlled by changing a monomer ratio to adjust a hydrophilic-lipophilic balance value of the catalyst, adapting to a reaction of an organic phase with an aqueous phase. Furthermore, the catalyst is insoluble in conventional solvents, and has a desirable effect in immobilizing nanoscale metallic copper, prolonging a service life of the catalyst.

Abstract: A downhill target acceleration control system for a vehicle is provided, which includes the vehicle, a road grade sensor, an acceleration sensor, and a processor. The processor stores an acceleration target value, determines the mass of the vehicle, and detects whether a downhill acceleration of the vehicle exceeds the target value by more than a threshold amount. If so, the processor is configured to receive and implement a driver-initiated change to the downhill target acceleration value, without input from the accelerator or brake. Based on the downhill acceleration, the target value, and the mass, the processor generates a negative power train torque request to reduce the downhill acceleration of the vehicle. If the acceleration of the vehicle is then below the target acceleration by more than a second threshold amount, the processor reduces the negative power train torque request to increase the downhill acceleration of the vehicle.

Abstract: Examples of the presently disclosed technology provide systems and methods for intelligently withholding selected basic safety messages (or other similar messages) from transmission by determining that current vehicle state-related information contained in the selected BSMs is redundant to predicted vehicle state-related information contained in a previously transmitted maneuver message (or other similar messages). Accordingly, examples of the presently disclosed technology can reduce strain on wireless communication channel resources (e.g., proximate to large traffic environments) by reducing the number of messages exchanged among connected vehicles—while preserving the traffic safety and efficiency advantages associated with such communication.
