    Abstract: A hierarchical control system for torque distribution of hub motor-driven electric vehicles constructs a hierarchical controller with upper and lower layers. An upper layer torque distribution controller's drive torque distribution control strategy is determined through a fuzzy control module. A lower layer torque distribution controller receives the torque, yaw velocity, and side-slip angle from the upper layer torque distribution controller and performs drive torque distribution control based on the motor efficiency map or tire slip rate by using the torque, yaw velocity, side-slip angle and actual values of vehicle feedback to obtain a generalized torque output to a wheel hub motor model for calculating to obtain a target torque and inputting it into a 7-degree-of-freedom vehicle model. The 7-degree-of-freedom vehicle model feeds back vehicle states to the upper layer torque distribution controller to form a closed-loop control, achieving energy-saving control and improving handling stability and safety.

    Abstract: A SDT computation system is provided. The SDT computation system includes a SDT module, an ACAM array, and a mapping module. The SDT module is for outputting a final probability and configured to provide a SDT structure with a root node and deeper inner nodes for calculating probability, in which the final probability of each leaf node of the SDT structure is a product of all of node probabilities along a path from the root node to each leaf node, and wherein a final output of the SDT module is from a leaf with the highest probability. The mapping module is configured to map the SDT structure into the ACAM array, such that each of the ACAM cells in the ACAM array has a threshold programmed to be a parameter for a node in a path leading towards the leaf node of the SDT structure.

    Abstract: A method for generating a signature of a spam message includes determining one or more classification attributes and one or more clustering attributes contained in successively intercepted first and second electronic messages. The first electronic message is classified using a trained classification model for classifying electronic messages based on the one or more classification attributes. The first electronic message is classified as spam if a degree of similarity of the first electronic message to one or more spam messages is greater than a predetermined value. A determination is made whether the first electronic message and the second electronic message belong to a single cluster based on the determined one or more clustering attributes. A signature of a spam message is generated based on the the identified single cluster of electronic messages.

    Abstract: A vehicular driving assistance system includes an exterior viewing camera disposed at a vehicle and viewing exterior of the vehicle. Image data captured by the camera is provided to and processed at an electronic control unit (ECU). The ECU performs processing tasks for multiple vehicle systems. The vehicular driving assistance system is operable to wirelessly upload captured image data to the cloud for processing at a remote processor. Processing tasks with a higher priority are determined at the ECU to be higher priority tasks. Responsive to determination at the ECU of a higher priority task, the vehicular driving assistance system (i) processes captured image data at the ECU for the higher priority task and (ii) uploads captured image data to the cloud for processing at the remote processor of processing at the remote processor.
