Abstract: Techniques for braking an autonomous vehicle include providing a pressurized fluid stream from a plurality of pressurized fluid sources to a plurality of pressure-controlled electronic braking assemblies; providing the pressurized fluid stream from a pressurized fluid control output of a first pressure-controlled electronic braking assembly directly to a pressurized fluid control input of a second pressure-controlled electronic braking assembly; providing the pressurized fluid stream from the second pressure-controlled electronic braking assembly to at least one vehicle brake set; providing sensor output data from one or more vehicle sensors to a plurality of electronic control units; and based at least in part on the sensor output data, controlling at least one of the first or second pressure-controlled electronic braking assemblies to adjust a pressure of the pressurized fluid stream from at least one of the first or second pressure-controlled electronic braking assemblies to the vehicle brake set.

Abstract: The technology relates to autonomous vehicles for transporting cargo and/or people between locations. Distributed sensor arrangements may not be suitable for vehicles such as large trucks, busses or construction vehicles. Side view mirror assemblies are provided that include a sensor suite of different types of sensors, including LIDAR, radar, cameras, etc. Each side assembly is rigidly secured to the vehicle by a mounting element. The sensors within the assembly may be aligned or arranged relative to a common axis or physical point of the housing. This enables self-referenced calibration of all sensors in the housing. Vehicle-level calibration can also be performed between the sensors on the left and right sides of the vehicle. Each side view mirror assembly may include a conduit that provides one or more of power, data and cooling to the sensors in the housing.

Abstract: The technology relates to the prediction and handling of tire blowouts for vehicles operating in a self-driving (autonomous) mode. Aspects involve determining a likelihood of tire failure, including actions the vehicle may take to reduce the likelihood of failure. Pre-trip and real-time system checks can be taken. A vehicle model including the tires may be employed in blowout prediction. The on-board system may store received data and detected sensor regarding tire pressure and temperature, which can be evaluated based on the model in order to avoid or minimize the likelihood of a blowout given various factors. The factors can include the load weight and distribution of cargo, current and upcoming weather conditions on the route, the number of miles traveled per tire, and detected obstructions, such as potholes, debris or other roadway impairments. Should a blowout occur, the autonomous system may immediately take any necessary corrective action.

Abstract: The technology relates to enhancing the operation of autonomous vehicles. Extendible sensors are deployed based on detected or predicted conditions around a vehicle while operating in a self-driving mode. When not needed, the sensors are fully retracted into the vehicle to reduce drag and increase fuel economy. When the onboard system determines that there is a need for a deployable sensor, such as to enhance the field of view of the perception system, the sensor is extended in a predetermined manner. The deployment may depend on one or more operating conditions and/or particular driving scenarios. These and other sensors of the vehicle may be protected with a rugged housing, for instance to protect against damage from the elements. And in other situations, deployable foils may extend from the vehicle's chassis to increase drag and enhance braking. This may be helpful for large trucks in steep descent situations.

Abstract: The technology relates to assisting large self-driving vehicles, such as cargo vehicles, as they maneuver towards and/or park at a destination facility. This may include a given vehicle transitioning between different autonomous driving modes. Such a vehicles may be permitted to drive in a fully autonomous mode on certain roadways for the majority of a trip, but may need to change to a partially autonomous mode on other roadways or when entering or leaving a destination facility such as a warehouse, depot or service center. Large vehicles such as cargo truck may have limited room to maneuver in and park at the destination, which may also prevent operation in a fully autonomous mode. Here, information from the destination facility and/or a remote assistance service can be employed to aid in real-time semi-autonomous maneuvering.

Abstract: The technology relates to enhancing or extending the field of view of sensors for vehicles configured to operate in an autonomous driving mode. One or more mirrors are used to reflect or redirect beams emitted from onboard sensors that would otherwise be wasted, for instance due to obstruction by a portion of the vehicle or because they are emitted at high pitch angles to the side. The mirrors are also used to redirect incoming beams from the external environment toward one or more of the onboard sensors. Using mirrors for such redirection can reduce or eliminate blind spots around the vehicle. A calibration system may be employed to account for mirror movement due to vibration or wind drag. Each mirror may be a front surface mirror. The mirrors may be positioned on the vehicle body, on a faring, or extending from a sensor housing on the vehicle.

Abstract: The technology provides for a system and method to secure a processing device in a socket in high shock and vibration environments, such as inside a vehicle. The processing device may be fitted in the socket, which may be soldered on a circuit board. A mounting plate may be attached to the circuit board. The processing device may be arranged between the circuit board and the mounting plate such that the processing device may be secured to the socket by a compression force applied by the mounting plate. The mounting plate may further provide cooling for the processing device.
