  • Patent number: 10974719
    Abstract: A mobile object control system has an SfM unit detecting distance to an object imaged by a monocular camera by using the SfM algorithm, a first-stop-position output unit outputting a first stop position, a second-stop-position calculating unit calculating a second stop position closer than the first stop position, and a control unit controlling travel of a mobile object. The control unit controls the mobile object so as to stop at the second stop position. When a predetermined starting condition is satisfied, the control unit controls the mobile object so as to start. The SfM unit detects the distance to an object by using an image captured by the monocular camera after the mobile object starts. When a result of detection of the distance of the object by the SfM unit is obtained, the control unit uses the detection result for control of the travel.

  • Patent number: 10800407
    Abstract: A driving control device of a vehicle includes a brake device and an ECU. The brake device is configured to apply a braking force to wheels. The ECU is configured to perform driving support control by calculating target deceleration of the vehicle and controlling the brake device such that deceleration of the vehicle reaches the target deceleration, to stop the driving support control when the driving support control is unable to be performed normally, and to determine whether or not a driver is in an abnormal state. The ECU is configured to decelerate the vehicle by controlling the deceleration of the vehicle so as to reach a predetermined value or more, when the driving support control is unable to be performed normally due to factors other than abnormality of the braking device in a situation where a determination that the driver is in an abnormal state is made.

  • Patent number: 10800415
    Abstract: Methods and systems are provided for electrically-assisted engine braking. In one example, a method may include operating a turbocharger by an electric motor during engine braking to increase air flow to an engine intake. The enhanced air flow into the engine intake increases an exhaust manifold pressure, thus increased a braking force provided by engine braking.

  • Patent number: 10787156
    Abstract: A method of diagnosis and prognosis for various operative systems is provided so that maintenance can be efficiently and effectively scheduled and provided. The invention is applicable to a broad range of systems, but particularly to aircraft brake systems and tires. An aircraft brake may be modeled by attributing brake wear factor values to various parameters associated with the aircraft brake that impact wear. Over the course of time and during braking events, the brake wear factor values are summed and a running total of that sum is kept over the life of the brake. At a point in time when the sum of weighted factors exceeds a preset threshold, an indicia is generated that service is required.

    Abstract: A real-time perception adjustment and correction and driving adaption method for autonomous driving is provided. The system will analyze the driving behaviors of surrounding vehicles surrounding an ADV, which is utilized to improve its original perception based on the analysis and to adapt to the updated driving environment. In one embodiment, in addition to the perception information provided by the sensors, the system analyzes the behaviors of the surrounding vehicles based on the perception information. Based on the behaviors of the surrounding vehicles, the system may detect there is may be an obstacle that has not been detected based on the perception information. Alternatively, the system may detect that an obstacle determined based on the perception information actually may not exist based on the behaviors of the surrounding vehicles. The paths created for the ADV may then adjusted accordingly to improve the autonomous driving of the ADV.

    Abstract: An emergency stop system includes a hazard switch that is a momentary switch, an automatic stop controller that performs automatic stop control for causing a vehicle to automatically stop when a predetermined condition is met, and a hazard light controller that controls hazard lights. While automatic stop control is not being performed, the hazard light controller switches the hazard lights between a flashing state and a turned-off state each time a user presses the hazard switch. The hazard light controller brings the hazard lights into the flashing state upon start of the automatic stop control, and turns off the hazard lights (i.e., transitions the hazard lights to the turned-off state) upon depression of the hazard switch while the hazard lights are flashing during execution of the automatic stop control.

  • Patent number: 10767994
    Abstract: A sensor output correction system is provided which is capable of minimizing a risk that a correction value for use in zero-point correction differs from an actual deviation of a zero-point. An ECU includes a travel road information acquisition portion which obtains a curvature of a travel road on which a system-mounted vehicle is traveling and a vehicle information acquisition portion which obtains a detected value of a yaw rate sensor. The ECU determines whether the system-mounted vehicle is traveling on a straight path or not based on the curvature derived by the travel road information acquisition portion. The ECU determines a value (i.e., a zero-point equivalent value) which corresponds to a deviation of a current zero point of the yaw rate sensor based on detected values of the yaw rate sensor sampled while the system-mounted vehicle is moving on the straight path. The ECU determines a correction value which is subtracted from the detected value using the zero-point equivalent value.
