Abstract: Embodiments presented herein include systems and methods for cooling a device, such as a computing system for an autonomous vehicle. In one or more embodiments, a linear drive actuator may be employed to circulate cooling fluid (or coolant) to the computing system. Unlike typical hydraulic or linear actuators, embodiments herein are capable of consistent directional circulation of the fluid while the actuator is moving in both forward and backward directions. Using a linear actuator not only uses fewer parts as compared to current cooling systems, but such embodiments have additional benefits. A linear actuator cooling system can use a smaller motor than traditional pump cooling systems, has more control relative to rate and pressure, produces less noise, produces fewer vibrations, and has a longer lifespan. Embodiments may also be configured to facilitate circulation of the coolant even in the event of a controller or motor actuator malfunction.

Abstract: Data is received from a plurality of sensors mounted on an ADV being held to a standstill. A status of the ADV including a rolling speed of the ADV is detected based on the data from the plurality of sensors. One of a primary brake or a secondary brake is activated, in response to detecting the status of the ADV being a first status including the rolling speed being higher than zero and lower than a first predetermined speed threshold. An electronic parking brake is activated, in response to detecting the status of the ADV being a second status including the rolling speed being higher than the first predetermined speed threshold and lower than a second predetermined speed threshold. An engine brake may be used to reduce the crash damage, and a warning message (e.g., Message-4) may be generated.

Abstract: Embodiments herein relate to robust methodologies for autonomous parking. In one or more embodiments, an autonomous vehicle may determine the slope of a road based upon one or more inputs and a pre-defined slope definition and may also determine curb/no curb status of a parking location. Given the determined road conditions, such as slope and no curb/curb, embodiments determine wheel direction and angle that the vehicle should achieve to properly park. Embodiments also include countermeasures if one or more issues prohibit the vehicle from achieving a desired parking condition.

Abstract: Operating a vehicle with an open door creates risks. Embodiments herein consider both when a vehicle is in an autonomous driving (AD) mode and a manual mode. When in AD mode, if an occupant opens the doors while the vehicle is moving, the control system may lower the speed to stop and may park the vehicle (or not park it depending upon the control policy). If an occupant opens the doors when the vehicle is stationary, the control system may keep the vehicle from rolling and from brake system failures. When the vehicle is in a manual model and a door is opened when the vehicle is moving, a warning message may be triggered; whereas, if a door is opened when the vehicle is stationary, the control system may keep the vehicle from rolling and from brake system failures. Warning messages may be triggered for different stages/conditions.

Abstract: Sound signals are received by a plurality of microphones disposed on a top of an ADV. An analysis of the sound signals is performed based on a spectrum and a vibration intensity of the sound signals. A wheel which the sound signals come from and a thickness of a brake pad of the wheel is determine based on the analysis of the sound signals. A brake pad wear degree of the brake pad and how long the ADV can run with the brake pad within a safety range is determined. A warning message indicating warning information based on the brake pad wear degree is transmitted.

Abstract: Embodiments herein comprise monitoring factors related to braking of an autonomous vehicle. In response to determining, based upon data from one or more sensors, whether a failure state from a set of one or more failure states has occurred, a failure log is updated to record the occurrence of the detected failure state. In one or more embodiments, the failure states have associated severity levels, and the updated log and associated severities are used to determine a braking safety or failure metric for the vehicle. In one or more embodiments, if the vehicle has a metric corresponding to a rule that correlates the braking safety metric value to a set of one or more actions, the corresponding action(s) may then be implemented. For example, if the braking safety metric has a value corresponding to a rule that indicates the vehicle is unsafe, the vehicle is parked.
