  • Deceleration curb-based direction checking and lane keeping system for autonomous driving vehicles
    Patent number: 10549752
    Abstract: A lane departure detection system detects that an autonomous driving vehicle (ADV) is departing from the lane in which the ADV is driving based on sensor data captured when the ADV contact a deceleration curb such as a speed bump laid across the lane. When the ADV contacts the deceleration curb, the lane departure detection system detects and calculates an angle of a moving direction of the ADV vs a longitudinal direction of the deceleration curb. Based on the angle, the system calculates how much the moving direction of the ADV is off compared to a lane direction of the lane. The lane direction is typically substantially perpendicular to the longitudinal direction of the deceleration curb. A control command such as a speed control command and/or a steering control command is generated based on the angle to correct the moving direction of the ADV.

  • PERSONALIZED AND CRYPTOGRAPHICALLY SECURE ACCESS CONTROL IN TRUSTED EXECUTION ENVIRONMENT
    Publication number: 20200034528
    Abstract: An access control system includes a processor configured to provide a trusted execution environment isolated from a rich execution environment. A rich OS operates in the rich execution environment while a trusted OS operates in the trusted execution environment. An access monitoring module operates within the kernel of the rich OS and a trusted application operates in the trusted OS. The access monitoring module intercepts file requests directed at the file systems of the rich OS, and forwards the file requests to the trusted application. The trusted application then evaluates whether the file request is permitted and provides the access monitoring module with a response. The access monitoring module forwards the request to the file system only if the trusted application approves the request.

  • Method and system for autonomous vehicle speed following
    Patent number: 10534364
    Abstract: In one embodiment, an autonomous driving vehicle (ADV) speed following system determines how much and when to apply a throttle or a brake control of an ADV to maneuver the ADV around, or to avoid, obstacles of a planned route. The speed following system calculates a first torque force to accelerate the ADV, a second torque force to counteract frictional forces and wind resistances to maintain a reference speed, and a third torque force to minimize an initial difference and external disturbances thereafter between predefined target speed and actual speed of the ADV over a planned route. The speed following system determines a throttle-brake torque force based on the first, second, and third torque forces and utilizes the throttle-brake torque force to control a subsequent speed of the ADV.

  • Method and system for updating maps based on control feedbacks of autonomous driving vehicles
    Patent number: 10488205
    Abstract: In one embodiment, when an ADV is driving on a road segment, a driving parameter is recorded in response to a first control command. A difference between the first driving parameter and a target driving parameter corresponding to the first control command is determined. In response to determining that the difference exceeds a predetermined threshold, a second control command is issued to compensate the difference and cause the ADV to drive with a second driving parameter closer to the target driving parameter. A slope status of the road segment is derived based on at least the second control command. Map data of a map corresponding to the road segment of the road is updated based on the derived slope status. The updated map can be utilized to generate and issue proper control commands in view of the slope status of the road when the ADV drives on the same road subsequently.
