  • Patent number: 10452074
    Abstract: When an ADV is detected to transition from a manual driving mode to an autonomous driving mode, a first pedal value corresponding to a speed of the ADV at a previous command cycle during which the ADV was operating in the manual driving mode is determined. A second pedal value is determined based on a target speed of the ADV at a current command cycle during which the ADV is operating in an autonomous driving mode. A pedal value represents a pedal percentage of a maximum pedal pressure or maximum pedal pressed distance of a throttle pedal or brake pedal from a neutral position. A speed command is generated and issued to the ADV based on the first pedal value and the second pedal value, such that the ADV runs in a similar acceleration before and after switching from the manual driving mode to the autonomous driving mode.

  • Patent number: 10442435
    Abstract: In one embodiment, when speed control command (e.g., throttle, brake commands) is issued based on a target speed, a first feedback parameters is determined based on an expected speed and an actual speed of the ADV in response to the speed control command. A second feedback parameter is determined by applying a speed control parameter adjustment (SCPA) model to a set of input parameters that are captured or measured at the point in time. The set of input parameters represents a driving environment of the ADV at the point in time. One or more control parameters of a speed controller of the ADV is adjusted based on the first feedback parameter and the second feedback parameter, where the speed controller is configured to generate and issue speed control commands. Subsequent speed control commands can be generated based on the adjusted speed control parameters of the speed controller.

  • Patent number: 10435015
    Abstract: In one embodiment, a driving scenario is determined for a next route segment or route for an autonomous vehicle. In response, a lookup operation is performed in a scenario/delay mapping table to locate a mapping entry that matches the determined driving scenario. The scenario/delay mapping table includes a number of mapping entries. Each mapping entry maps a particular driving scenario to a system delay that has been calculated for that particular driving scenario. Thereafter, the autonomous vehicle is controlled and driven in view of the system delay corresponding to the driving scenario at the point in time, including issuing control commands according to timing compensating the system delay under the circumstances.

  • Patent number: 10407076
    Abstract: In one embodiment, planning data is received, for example, from a planning module, to drive an autonomous driving vehicle (ADV) from a starting location and a destination location. In response, a series of control commands are generated based on the planning data, where the control commands are to be applied at different points in time from the starting location to the destination location. A cost is calculated by applying a cost function to the control commands, a first road friction to be estimated in a current trip, and a second road friction estimated during a prior trip from the starting location to the destination location. The first road friction of the current trip is estimated using the cost function in view of a prior termination cost of the prior trip, such that the cost reaches minimum.

    Abstract: A method for forming a semiconductor device includes forming a first insulator layer on a first substrate of a first semiconductor material, implanting hydrogen ions into the first substrate to form a hydrogen-implanted layer, forming a recessed region in the first substrate, forming a second semiconductor material in the recessed region, and forming a second insulator layer over the second semiconductor material and the first substrate. The method also includes providing a second substrate with a third insulator layer disposed thereon, bonding the first substrate with the second substrate, and removing a lower portion of the first substrate at the hydrogen-implanted layer. A portion of the first substrate is removed to expose a surface of the second semiconductor material in the recessed region, thereby providing a layer of the first semiconductor material adjacent to a layer of the second semiconductor material on the second insulator layer.

  • Patent number: 10365649
    Abstract: In one embodiment, a lane departure detection system detects at a first point in time that a wheel of an ADV rolls onto a lane curb disposed on an edge of a lane in which the ADV is moving. The system detects at a second point in time that the wheel of the ADV rolls off the lane curb of the lane. The system calculates an angle between a moving direction of the ADV and a lane direction of the lane based on the time difference between the first point in time and the second point in time in view of a current speed of the ADV. The system then generates a control command based on the angle to adjust the moving direction of the ADV in order to prevent the ADV from further drifting off the lane direction of the lane.

  • Patent number: 10343685
    Abstract: In one embodiment, a driving scenario is identified for a next movement for an autonomous vehicle, where the driving scenario is represented by a set of one or more predetermined parameters. A first next movement is calculated for the autonomous vehicle using a physical model corresponding to the driving scenario. A sideslip predictive model is applied to the set of predetermined parameters to predict a sideslip of the autonomous vehicle under the driving scenario. A second next movement of the autonomous vehicle is determined based on the first next movement and the predicted sideslip of the autonomous vehicle. The predicted sideslip is utilized to modify the first next movement to compensate the sideslip. Planning and control data is generated for the second next movement and the autonomous vehicle is controlled and driven based on the planning and control data.

  • Patent number: 10331138
    Abstract: In one embodiment, motion planning and control data is received, where the motion planning and control data indicates that an autonomous vehicle is to move from a first point to a second point of a path within a predetermined route. In response to the motion planning and control data, the path from the first point to the second point is segmented into multiple path segments. For each of the path segments, one of predetermined driving scenes is identified that matches motion characteristics of the corresponding path segment. The motion planning and control data associated with the path segments is modified based on predetermined motion settings of the path segments. The autonomous vehicle is driven through the path segments of the path based on the modified motion planning and control data.

  • Publication number: 20190168769
    Abstract: In one embodiment, a steering control delay is measured, where the steering delay represents the delay between the time of issuing a steering control command and the time of a response from one or more wheels of an autonomous vehicle. A speed control delay is measured between the time of issuing a speed control command and the time of a response from one or more wheels of the autonomous vehicle or the time of supplying pressure to the gas pedal or brake pedal. In response to a given route subsequently, an overall system delay is determined based on the steering control delay and the speed control delay using a predetermined algorithm. Planning and control data is generated in view of the system delay for operating the autonomous vehicle.

  • Patent number: 10289110
    Abstract: In one embodiment, a number of steering rate candidates are determined for a steering control command of operating an autonomous vehicle. For each of the steering rate candidates, a steering rate cost is calculated for the steering rate candidate by applying a predetermined cost function, including calculating a first cost for the steering rate candidate based on a difference between a target steering position and a current steering position of the autonomous vehicle using a first predetermined cost function. One of the steering rate candidates having a lowest steering rate cost is selected as a target steering rate. A steering control command is generated based on the selected steering rate candidate to control a steering wheel of the autonomous vehicle.
