The invention discloses a network monitoring and analyzing system under an environment of a virtual machine. The system comprises a network data multiplexing module, a lightweight level virtual machine manager module, a virtual machine control module, a service virtual machine module and an I / O access path optimization module, wherein the network data multiplexing module and the lightweight levelvirtual machine manager module are positioned in an operating system of a host computer, the virtual machine control module and the service virtual machine module are positioned on the operating system of the host computer; and the I / O access path optimization module is positioned in the operating system of the host computer and the service virtual machine. The network monitoring and analyzing system is based on the virtual machine and realizes the network data multiplexing of a single physical machine to a plurality of network monitoring and analyzing service programs, thereby providing a plurality of monitoring and analyzing functions for the same network data in real time, realizing safe isolation between the service programs and dynamically adjusting and distributing resource to the service programs according to requirements. The network monitoring and analyzing system overcomes the problems that the prior network monitoring and analyzing system has resource competition, low safety, instability of the system, uneasy expansion and the like.

The invention discloses a method for calculating the torque required by an electric automobile driver. The method includes the following steps that the style of the driver and the driving intension of the driver are detected, and the required torque is calculated; the safe interval is detected, and safety modification is conducted on the required torque. According to the method, the driving style and the driving intention of the driver are recognized, torque coefficients required under different styles and different intentions are adjusted, and therefore power is obviously improved for a dynamical type driver under the situation the opening degree does not approach the opening degree of a saturated accelerator pedal, power changes are gentle for an economical type driver under the situation of the normal small pedal opening degree, the situation that economical efficiency is reduced when the load changes of a power system are overlarge is easily reduced, the required torque can be increased according to the emergency degree of acceleration, and the instant requirement of the driver for the dynamic property of the automobile is met. Due to the fact that the maximum torque required by the driver is limited within the critical safety modification distance, when the calculation result is smaller than zero, the torque required by automobile power is forced to reset; the automobile can safely run after other automobiles, and tailgating traffic accidents are avoided.

The invention discloses a method of dynamic bandwidth adjustment in bandwidth access system, which includes the following steps: the bandwidth access equipment is allocated and stored with business information; the bandwidth access equipment monitors and identifies the business information of users' choice in the data packet dispatched; according to the identified business information, the bandwidth access information increases or releases the bandwidth of corresponding users. The invention reduces the update and storage steps of resources reservation soft state, with easier realization. At the same time, the dynamic bandwidth distribution method adopted by the invention can meet the dynamic requirements of users random usage, distribute system bandwidth reasonably to the maximum degree and guarantee the experience quality and service quality of the business used by users.

The invention relates to an acceleration pedal torque request calibration method, which belongs to the technical field of vehicle torque demand calibration. First, determine the driving force and running resistance curves of the car according to the basic parameters of the car, then determine the driving force request curve at the wheel end when the accelerator pedal is 100%, calculate the driving force request curve at the wheel end with a partial accelerator pedal opening, and finally set the accelerator pedal at the wheel end. The drive force request is converted to the crankshaft end of the engine to obtain the accelerator pedal demand torque map that needs to be output by the engine in multiple gears. The calibration method described in the present invention is novel and practical, can reduce the impact of shifting gears, realizes the easy control of the vehicle speed by the driver by forming an insensitive area of ​​the accelerator pedal near the driving resistance curve of the vehicle, and effectively improves the driving quality of the vehicle.

The invention discloses a method for improving gear shifting quality of a vehicle automatic transmission under the acceleration condition. The method comprises the following steps that a training signal sample and a training parameter sample are obtained; an acceleration condition recognition model is set, and training is carried out; through the acceleration condition recognition model, the acceleration condition type corresponding to work parameters is recognized; through the gear shifting quality comprehensive evaluation indicator, the clutch friction moment during acceleration condition gear shifting can be calculated, and through the clutch friction moment, clutch gear shifting is corrected. The method has the beneficial effects that a discrimination function is built for carrying outacceleration condition recognition, the recognition accuracy is high, robustness is high, multi-classifying of the condition can be achieved, according to the different acceleration condition, different variable change optimal schemes are set, according to different power needs, the gear shifting time and the gear shifting impact degree can be intelligently deployed, and the need of drivers withdifferent driving styles for the vehicle power can be met.
