  • Patent number: 10369988
    Abstract: Method and apparatus are disclosed for autonomous parking of vehicles in perpendicular parking spots. An example vehicle includes a front corner, a camera, and an autonomous vehicle parker. The autonomous vehicle parker is to detect, via the camera, a perpendicular parking spot and an outer boundary of the perpendicular parking spot, determine a linear parking path located within the perpendicular parking spot and based on the outer boundary, and autonomously turn into the perpendicular parking spot such that the front corner travels along the linear parking path.

  • Patent number: 10330644
    Abstract: Methods and systems are provided for conducting measurements of relative humidity using an ultrasonic sensor. In one example, a plurality of ultrasonic signals having different frequencies are transmitted from a single sensor, and attenuation values of reflected signals are determined only for those signals determined to have the same transit time from transmission to receipt, and where frequency of the plurality of ultrasonic signals may be changed responsive to an indication that the signals may be below a signal-to-noise threshold. In this way, by determining a difference between attenuation values between pairs of signals, where the signals comprise different frequencies and where the signals comprise the same transit times, relative humidity may be accurately determined.

  • Patent number: 10302596
    Abstract: Methods and systems are provided for conducting measurements of relative humidity via the use of an ultrasonic sensor. In one example, the ultrasonic sensor for conducting the relative humidity measurement is selected from a plurality of ultrasonic sensors positioned at various locations on the vehicle, and where the selecting is accomplished in some examples via the use of one or more onboard cameras configured to identify suitable objects that are stationary with respect to the vehicle. In this way, robustness and accuracy of relative humidity measurements may be improved, lifetime of individual ultrasonic sensors may be extended, and vehicle operating conditions that depend on accurate relative humidity measurements may be improved.

  • Patent number: 10281921
    Abstract: Method and apparatus are disclosed for autonomous parking of vehicles in perpendicular parking spots. An example vehicle includes a front corner, a sensor, and a parking controller. The parking controller is to detect, via the sensor, a perpendicular parking spot and determine a linear parking path located within the perpendicular parking spot along which the front corner is to travel. The parking controller also is to determine an approaching turn path to the linear parking path and autonomously turn along the approaching turn path and the linear parking path into the perpendicular parking spot.

  • Patent number: 10229231
    Abstract: A method for generating training data. The method may include executing a simulation process. The simulation process may include traversing one or more virtual sensors over a virtual road surface defining a plurality of virtual anomalies that are each sensible by the one or more virtual sensors. During the traversing, each of the one or more virtual sensors may be moved with respect to the virtual road surface as dictated by a vehicle-motion model modeling motion of a vehicle driving on the virtual road surface while carrying the one or more virtual sensors. Virtual sensor data characterizing the virtual road surface may be recorded. The virtual sensor data may correspond to what a real sensor would have output had it sensed the road surface in the real world.

  • Patent number: 9841765
    Abstract: Systems and methods for curb detection for parking are disclosed. An example vehicle parking assist system includes a processor and memory. An example program stored in the memory is configured to move a vehicle using a set of maneuvers to park the vehicle in a parking space based on an estimated location of a curb. The example program is also configured to compare a first yaw rate to a reference yaw rate to detect when the vehicle contacts the curb. Additionally, the example program is configured to move the vehicle using an adjusted set of maneuvers based on an actual location of the curb.

  • Publication number: 20170083794
    Abstract: A method for testing the performance of one or more anomaly-detection algorithms. The method may include obtaining sensor data output by a virtual sensor modeling the behavior of an image sensor. The sensor data may correspond to a time when the virtual sensor was sensing a virtual anomaly defined within a virtual road surface. One or more algorithms may be applied to the sensor data to produce at least one perceived dimension of the virtual anomaly. Thereafter, the performance of the one or more algorithms may be quantified by comparing the at least one perceived dimension to at least one actual dimension of the virtual anomaly as defined in the virtual road surface.
