    • A method of measuring rolling resistance of a machine is disclosed. The method may include determining a drive axle torque value of the machine and calculating a total effective grade value using the drive axle torque value. The method may further include determining at least one drivetrain efficiency loss factor value and calculating a total drivetrain efficiency loss value of the machine using the at least one drivetrain efficiency loss factor value. The method may also include determining position data of the machine and calculating an actual grade value based on the position data. The method may additionally include calculating a rolling resistance value of the machine by subtracting the actual grade value and the drivetrain efficiency loss value from the total effective grade value and outputting the rolling resistance value.
    • 公开了一种测量机器滚动阻力的方法。 该方法可以包括确定机器的驱动轴扭矩值并使用驱动轴扭矩值计算总有效等级值。 该方法还可以包括使用至少一个传动系效率损失因子值来确定至少一个传动系效率损失因子值并计算机器的总传动系效率损失值。 该方法还可以包括确定机器的位置数据并基于位置数据计算实际坡度值。 该方法可以另外包括通过从总有效等级值中减去实际坡度值和传动系效率损失值并输出滚动阻力值来计算机器的滚动阻力值。

    • The present invention discloses a method for implementing device grouping and interactions between grouped devices. In a network, a device creating a device group sends an advertisement message carrying identification information of a device group to which it belongs, to the network. After receiving the advertisement message, a network device which wants to join in the corresponding device group joins in the device group identified by the corresponding advertisement message. When two network devices interact with each other, the method further comprises: sending by an initiating device, an access request to an accessed device; judging by the device receiving the access request, whether the device sending the request is a trusted device thereof or not, if so, interacting by both parties with each other; otherwise, denying the access request, or determining a common trusted third party together with the initiating device; acquiring by the initiating device, key information of the accessed device from the common trusted third party, and interacting with the accessed device by using the acquired key information. The method can support one and the same device to join in deferent groups while facilitating the device management, and can achieve secure authentication based communication interactions between any devices.
    • 本发明公开了一种用于实现分组设备之间的设备分组和交互的方法。 在网络中,创建设备组的设备向网络发送携带其所属的设备组的标识信息的广播消息。 在接收到广告消息之后,希望加入相应设备组的网络设备加入由相应广告消息标识的设备组中。 当两个网络设备彼此交互时,该方法还包括:由发起设备向被访问设备发送访问请求; 由接收到访问请求的设备判断,发送请求的设备是否是可信设备,如果是,则由双方互相交互; 否则拒绝访问请求,或者与发起设备一起确定公共可信第三方; 由所述发起设备从所述公共受信任的第三方获取所访问设备的密钥信息,并且通过使用所获取的密钥信息与所访问的设备进行交互。 该方法可以支持同一设备加入不同的组,同时方便设备管理,并且可以实现任何设备之间基于安全认证的通信交互。
