  • Patent number: 11167749
    Abstract: A hybrid electric powertrain for a vehicle includes an engine, electric machine, torque converter having a pump, turbine, and torque converter clutch (“TCC”) configured, when applied, to lock the pump to the turbine, a one-way engine disconnect clutch connected to the turbine, a transmission, and a controller. A transmission input shaft directly couples to the electric machine, and is selectively coupled to the engine via the disconnect clutch. An output shaft is connectable to road wheels of the vehicle. The controller, in response to an engine-off request, determines turbine and pump speeds of the turbine and pump, respectively, registers that the engine is in an engine-off state when the pump speed is less than the turbine speed, and executes an electric vehicle (“EV”) mode shift using machine torque from the electric machine when the pump speed is zero during the engine-off state.

  • Patent number: 11169242
    Abstract: A system and method for locating a mobile device relative to a vehicle using mechanical waves and modulation techniques. A high frequency carrier wave that is generally inaudible to humans is modulated with a low frequency baseband signal that provides for accurate localization in order to generate a modulated signal. The modulated signal is a mechanical or pressure wave, as opposed to an electromagnetic (EM) wave, that is transmitted by one or more speaker(s) and is received by one or more microphone(s). In one example, the modulated signal is transmitted from a speaker on the mobile device (e.g., a smart phone) to a number of microphones mounted on the vehicle at specific distances apart, so as to establish multiple localization paths whose differences in phase can be used to determine the location of the mobile device, relative to the vehicle.

  • Patent number: 11170584
    Abstract: An automatic fault isolation and diagnosis system includes a cloud-based data system having multiple machine-readable troubleshooting procedures stored therein. A vehicle fault code is generated by one of multiple vehicle control devices of a vehicle platform. The fault code defines an issue with at least one system or component of the vehicle platform. A data transfer device within the vehicle platform receives the fault code and forwards the fault code to the cloud-based data system. The fault code is received and analyzed in the cloud-based data system to initially determine if the fault code is directed to and can be automatically corrected by one of the stored machine-readable troubleshooting procedures.

  • Patent number: 11164399
    Abstract: Various technologies described herein pertain to detecting sensor data to be annotated for autonomous vehicle perception algorithm training. A label identifying a type of an object is assigned to an object at a particular location in an environment based on sensor data generated by a sensor system of an autonomous vehicle for a given time. The label is assigned based on a confidence score assigned to the type of the object by a computer-implemented perception algorithm. The computer-implemented perception algorithm assigns the confidence score to the type of the object based on the sensor data corresponding to the particular location in the environment for the given time. An output of a heuristic is generated based on the label and/or the confidence score, and the output of the heuristic is used to control whether to cause the sensor data for the given time to be annotated.

  • Patent number: 11166009
    Abstract: Sensors coupled to a vehicle are calibrated using a dynamic scene with sensor targets around a motorized turntable that rotates the vehicle to different orientations. The sensors capture data at each orientation along the rotation. The vehicle's computer identifies representations of the sensor targets within the data captured by the sensors, and calibrates the sensor based on these representations. The motorized turntable may confirm that rotation has stopped to the vehicle to trigger sensor capture, and the vehicle may communicate completion of sensor capture at an orientation to the motorized turntable to trigger further rotation.

  • Patent number: 11162798
    Abstract: The present technology provides a system that can update aspects of an authoritative map portion stored on an autonomous vehicle using low-resolution data from the at least one sensor of the autonomous vehicle, and therefore avoids the need for dispatching the special purpose mapping vehicle for these updates. The captured low-resolution data can be compared with the high-resolution map portion to determine that the sensor data reflects a feature in a way that is inconsistent with how that feature is represented in the authoritative map portion. The sensor data can then be used to relabel the authoritative map portion.

  • Patent number: 11163820
    Abstract: A computing system that can receive an object search request from a user indicating a request to search for a specific object in an area traversed by one or more autonomous vehicle. The object search request can include a set of physical characteristics of the specific object. The computing system can then transmit a signal to an autonomous vehicle indicating a request for the autonomous vehicle to search for the specific object. The signal can cause the autonomous vehicle to transmit an image, selected based on a physical characteristic of the object, to the computing system. The computing system can then generate a score indicative of a difference between one or more physical characteristic of the object in the image and the specific object. The computing system can then selectively transmit the image to a mobile device operated by the user based on the score.
