Abstract: According to one embodiment, a motion trajectory boundary is obtained based on a trajectory that has been planned to drive an ADV for a next time period. A safe driving area boundary is determined for the ADV based on perception data perceiving a driving environment surrounding the ADV. The motion trajectory boundary and the safe drivable area boundary are projected onto a map such as an HD map. A relative location of the ADV within the map relative to the motion trajectory and the safe drivable area boundary is determined. A fail-safe action or a fail operational action may be performed based on the relative location of the ADV in view of the motion trajectory boundary and the safe drivable area boundary.

Abstract: In one embodiment, a method for monitoring a localization function in an autonomous driving vehicle (ADV) can use known static objects as ground truths to determine when the localization function encounter errors. The known static objects are marked on a high definition (HD) map for the real-time driving environment. When the ADV detects one or more known static objects, the ADV can use sensor data, locations of the one or more static objects, and one or more error tolerance parameters to create a localization error tolerance area surrounding a current location of the ADV. The ADV can project the tolerance area on the HD map, performs a localization operation to generate an expected location of the ADV on the HD map, and determines whether the generated location falls within the projected tolerance area.

Abstract: A substrate for a metal oxide semiconductor field effect transistor, and a metal oxide semiconductor field effect transistor, are made available. The substrate encompasses: an n-doped epitaxial drift zone, a p?-doped epitaxial first layer disposed on the drift zone, a heavily n-doped second layer disposed on the first layer, and a terminal formed by p+ implantation, the first layer being in electrical contact with the terminal and being disposed laterally between the terminal and a trench, the trench being formed in the drift zone, in the first layer, and in the second layer. The substrate is characterized in that an implantation depth (P) of the p+ implantation is at least as great as a depth of the trench. The deep p+ implantation can separate adjacent trenches in such a way that a field can no longer attack a gate oxide because it is directed around the gate oxide.
