  • Patent number: 12365333
    Abstract: A forward collision-avoidance assist (FCA) system and method that prevents a too sensitive operation of anti-collision control such as unnecessary braking or an avoidance control due to sensing of an oncoming vehicle even when a risk of collision is lowered by temporary lane crossing performed based on a surrounding situation. The FCA system includes: a sensor unit to sense a situation in front of a subject vehicle; a collision avoidance logic adjuster configured to adjust a target selection condition for selecting an oncoming vehicle having a risk of collision based on forward situation data; a collision avoidance determiner configured to select the oncoming vehicle by applying the adjusted target selection condition and determine a collision risk value; and a collision avoidance controller configured to automatically control braking or steering of the subject vehicle when the collision risk value is greater than or equal to a preset value.

  • Patent number: 12280824
    Abstract: The techniques and systems herein enable ESA modification based on manual steering inputs. Specifically, a score is determined for a manual steering input to a host vehicle while an ESA is actively applying an ESA steering input to the host vehicle. The score quantifies an amount of additional steering input relative to the ESA steering input (e.g. additional steering angle, steering wheel torque). The ESA steering input is maintained, modified, or canceled based on the score. By doing so, the system is able to effectively adapt the ESA to the manual steering inputs thereby allowing for effective collision mitigation while ensuring that the vehicles operate as intended by the drivers.

  • Patent number: 12280841
    Abstract: When it is determined that there is no possibility of a driver performing a predetermined steering operation for moving a host vehicle in a lateral direction without involving a change in a final travel direction, a vehicle control device sets a steering reaction force to be greater than a standard reaction force. When it is determined that there is a possibility thereof, the vehicle control device sets the steering reaction force to be smaller than the standard reaction force, and sets an increase rate of the steering reaction force relative to an increase in the amount of steering operation from a predetermined point in time after it is determined that there is a possibility of the driver performing the predetermined steering operation and before the amount of steering operation in the predetermined steering operation becomes largest to be higher than an increase rate before the predetermined point in time.

  • Patent number: 12077231
    Abstract: A steer-by-wire system can be controlled using a hypothetical or virtual model of a conventional automotive steering system such as an electric power steering (EPS) system in which a steering wheel is mechanically linked to one or more road wheels. The model of the EPS system may be implemented in algorithms or instructions of software. In order to reconstruct driving feedback similar to the conventional steering system in the steer-by-wire system, the steer-by wire system may use the model of the EPS system. For example, a controller of the steer-by-wire system controls an angular velocity of a steering feedback actuator of the steer-by-wire system operably connected with the steering wheel so as to provide a steering feedback to a driver or operator using the model of the EPS system.

  • Patent number: 11958554
    Abstract: Model-based control of dynamical systems typically requires accurate domain-specific knowledge and specifications system components. Generally, steering actuator dynamics can be difficult to model due to, for example, an integrated power steering control module, proprietary black box controls, etc. Further, it is difficult to capture the complex interplay of non-linear interactions, such as power steering, tire forces, etc. with sufficient accuracy. To overcome this limitation, a recurring neural network can be employed to model the steering dynamics of an autonomous vehicle. The resulting model can be used to generate feedforward steering commands for embedded control. Such a neural network model can be automatically generated with less domain-specific knowledge, can predict steering dynamics more accurately, and perform comparably to a high-fidelity first principle model when used for controlling the steering system of a self-driving vehicle.

  • Patent number: 11679761
    Abstract: In one embodiment, a first trajectory is generated for a driving environment using control values allowed for a driving-by-wire system. If the trajectory includes a collision with an object, the ADV estimates the time of the collision and the relative speed between the ADV and the object at the time of the collision. A second trajectory is then generated for the driving environment using control values allowed for a human driver. The time of the collision and the relative speed between the ADV and the object at the time collision on the second trajectory are also estimated. The ADV then compares the two collision times and the two relative speeds, and based on the comparison, generates an alert message for the human driver to take over the control of the ADV.
