Steering Control Patents (Class 701/41)
  • Patent number: 11360482
    Abstract: Via a first processing thread, an ADV is controlled according to a first trajectory that was generated based on a first reference line starting at a first location. Concurrently via a second processing thread, a second reference line is generated based on a second location of the first trajectory that the ADV will likely reach within a predetermined period of time in future. The predetermined period of time is greater than or equals to an amount of time to generate a reference line for the ADV. The second reference line is generated while the ADV is moving according to the first trajectory and before reaching the second location. Subsequently, in response to determining that the ADV is within a predetermined proximity of the second location, a second trajectory is generated based on the second reference line without having to calculate the second reference line at the second location.

  • Patent number: 11358593
    Abstract: A dual direction accident prevention (DDAP) and assistive braking system (ABS) which detects both the risk of a frontal accident and a rear accident and then coordinates braking to prevent both if possible while giving priority to preventing a frontal accident. In the event of an imminent rear collision with an object or vehicle in front of a driver, the system will choose a braking force which minimizes the impact of the rear collision, while determining a safe approach toward the front obstacle. Furthermore, if a vehicle is approaching the driver and an accident is imminent, and there is no further room in front to reduce the effect of the imminent impact, the system prepares the vehicle and driver by bracing for impact by applying emergency brakes, tightening seatbelts, etc.

    Abstract: An ECU independently controls power supply to two winding systems in a motor on a per-winding-system basis based on current command values each calculated for a corresponding winding system in accordance with a target assist torque. When a first winding system fails, the ECU transitions from a first state in which the ECU causes the winding groups of the two winding systems to produce the target assist torque to a second state in which the ECU causes the winding group of the other normal winding system to produce the target assist torque. If the current command value for the normal winding system is equal to or below a current threshold value that is set with reference to zero or a value close to zero when the failed winding system recovers to its normal state in the second state, the ECU transitions from the second state to the first state.

  • Patent number: 11299203
    Abstract: In a cruise assist system, a turning angle controller executes at least one of an automatic cruise control task that automatically controls a turning angle of the vehicle, and an assist control task that controls the turning angle of the vehicle in accordance with an occupant's operation of the steering wheel. A holding determiner includes an input detector detecting an occupant's physical input to a steering shaft via a steering wheel based on at least one of a first type physical quantity and second type physical quantities. Each of the first and second physical quantities depends on rotational movement of the steering shaft. The first type physical quantity contains the occupant's physical input, and a disturbance input, which is different therefrom, to the steering shaft. The second type physical quantities have a physical relationship therebetween, which is changed depending on the occupant's physical input.

  • Patent number: 11299153
    Abstract: A vehicle traveling control apparatus comprises a driving support ECU. The driving support ECU determines whether or not a driver of a vehicle is under an abnormal state where the driver losses an ability to drive the vehicle. The driving support ECU executes a deceleration control to decelerate the vehicle after an abnormal determination time point at which it is determined that the driver is under the abnormal state. The driving support ECU decelerates a vehicle speed of the vehicle to within a predetermined low vehicle speed range and thereafter, causes the vehicle to travel at a speed within the low vehicle speed range.

  • Patent number: 11292458
    Abstract: Systems and methods are provided for generating trajectories for a vehicle user interface showing a driver's perspective view. Methods include generating an ego-vehicle predicted trajectory for an ego-vehicle; and generating at least one road agent predicted trajectory for a road agent that is external to the ego-vehicle. After the predicted trajectories are generated, the method continues by determining that at least one predicted trajectory overlaps either an object or another predicted trajectory, when displayed on the user interface showing a driver's perspective view. The method includes modifying the at least one road agent predicted trajectory to remove the overlap. The method then proceeds with updating a display of the user interface to include any modified road agent predicted trajectory. Systems include a trajectory-prediction module to execute the methods.

  • Patent number: 11288890
    Abstract: A vehicular driving assistance system includes a camera disposed at a vehicle and a control having an image processor that processes image data captured by the camera to determine lane markings demarcating a traffic lane in which the vehicle is traveling. The control, responsive to a map input to the control, estimates a path of travel for the vehicle to maintain the vehicle in the traffic lane in which the vehicle is traveling in situations where the lane markings demarcating the traffic lane in which the vehicle is traveling are not readily determinable. The system updates the estimated path of travel ahead of the vehicle even when no lane markings are determined present on the road ahead of the vehicle. The control adjusts processing of captured image data responsive at least in part to a driving situation that the vehicle is in.

  • Patent number: 11279403
    Abstract: A trailer reverse assist system includes a coupler angle detection sensor to detect a zero degree angle of the trailer relative to the vehicle. A drift controller receives signals from vehicle dynamics sensors. The drift controller is electrically connected with a trailer reverse assist module. When the vehicle is backing up the trailer on the intended straight line implied path and since the coupler angle sensor, detecting the zero degree angle, is not perfectly calibrated, based in the signals from the vehicle dynamics sensors, the drift controller 1) estimates a distance that the trailer has drifted from the straight line desired path and 2) in a closed-loop feedback manner, provides a drift correction signal to the trailer reverse assist module for modifying the value of the zero degree angle and thus cause adjustment of the steering system to realign the trailer towards the straight line implied path without manual steering intervention.
