Abstract: This application discloses a method and an apparatus for activating an ESC of an intelligent driving vehicle. In this method, an ESC activation probability is obtained after an intelligent driving function of the intelligent driving vehicle is enabled. A pre-exit signal of an ADS and a warning signal are outputted when the ESC activation probability is greater than a preset latch interval. The pre-exit signal indicates the ADS to maintain stability of a traveling status of the intelligent driving vehicle. The warning signal prompts a driver to take over the intelligent driving vehicle. A stability parameter of the intelligent driving vehicle is obtained, where the stability parameter represents a stability characteristic of the traveling status of the intelligent driving vehicle. When the stability parameter meets an ESC activation condition, the ESC of the intelligent driving vehicle is activated.

Abstract: Lining pipes (103) are routinely pulled through HDD boreholes from one end. As HDD borehole distances get longer, the total amount of friction experienced by the pipe will increase and therefore greater forces/stresses are applied to the pipes (103). For a given material and diameter of pipe (103), conventionally, the only way to handle these stresses is to increase the wall thickness of the pipe (103). The present invention provides at least one gripping device (201) on a line (107), movable through the interior of a pipe (103), and configured to grip an interior of the pipe (103). In this way, the gripping device (201) may be used to grip a pipe (103) at a point spaced from an end thereof, thereby reducing tensile forces on the pipe.
