Patent number: 10882516Abstract: Disclosed is a collision avoidance assisting apparatus which can execute an automatic braking process and an automatic steering process for avoiding collision with an obstacle. When the magnitude of a steering angle exceeds a predetermined threshold, the collision avoidance assisting apparatus determines that a driver has an intention of avoiding the collision by a steering operation and stops the automatic braking process and the automatic steering process. However, in such a case, the automatic braking process and the automatic steering process may be stopped when the steering angle exceeds the threshold as a result of execution of the automatic steering process. In view of this, when both the automatic braking process and the automatic steering process are being executed, the collision avoidance assisting apparatus continues the automatic braking process and the automatic steering process even when the magnitude of the steering angle is greater than the predetermined threshold.Type: GrantFiled: March 5, 2018Date of Patent: January 5, 2021Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Kohei Morotomi, Noriyuki Tsuruoka

Patent number: 10845202Abstract: An autonomous vehicle may access portions of a map to maneuver a roadway. The map may be split into one or more levels that represent different regions in space. For example, an overpass may be represented by one level while the road below the overpass may be on a separate level. A vehicle traveling on a particular level may use map data that is associated with that level. Furthermore, if the vehicle travels through a warp zone, it may transition from the current level to a destination level and thus begin to use map data associated with the destination level.Type: GrantFiled: January 24, 2018Date of Patent: November 24, 2020Assignee: Waymo LLCInventors: Christopher Paul Urmson, Michael Steven Montemerlo, Andrew Hughes Chatham, Daniel Trawick Egnor

Patent number: 10800392Abstract: Systems and methods for indicating the health of brakes on an aircraft or a ground vehicle. One method for monitoring brake health calculates the ratio of input energy to output energy during braking. The input energy is a function of commanded brake force and speed. The output energy may be measured by measuring the increase in temperature or the actual brake force over time during brake application. When using brake temperatures, the temperatures in a pair of brakes may optionally be compared. If the respective measured temperatures of the two brakes differ by an amount that exceeds a specified threshold, the system produces an indication that one brake may require repair or replacement. Variability due to operational and environmental factors that affect measured temperature can be reduced by comparing the measured brake temperatures for one brake with selected brake temperature data collected from the same brake during other landings under similar conditions.Type: GrantFiled: April 18, 2017Date of Patent: October 13, 2020Assignee: The Boeing CompanyInventors: Shahriar Alam, Daniel D.
