  • Publication number: 20230286573
    Abstract: A turning method for turning a steered wheel of a vehicle includes detecting a steering angle of a steering wheel; detecting an actual turning angle. The actual turning angle is an actual turning angle of the steered wheel. The method includes calculating a target turning angle of the steered wheel according to the detected steering angle. The method includes calculating a turning force command value to cause the actual turning angle to coincide with the target turning angle, based on a difference between the actual turning angle and the target turning angle. The method includes delaying a phase of the turning force command value with respect to the detected steering angle; and generating turning force to turn the steered wheel in accordance with the turning force command value having a phase delayed.

  • Patent number: 8447489
    Abstract: A vehicle driving operation support apparatus for a vehicle, includes a sensing section to sense a traveling condition of the vehicle including a surrounding condition inclusive of an obstacle around the vehicle, and a control section to calculate a risk potential for the vehicle in accordance with the traveling condition. The control section performs a support control to support the driver in accordance with the risk potential and performs an assist control to produce inducement simulating a condition change (such as a vehicle behavior) attributable to an increase of the risk potential, in accordance with the risk potential.

    Abstract: A vehicle driving operation support apparatus for a vehicle, includes a sensing section to sense a traveling condition of the vehicle including a surrounding condition inclusive of an obstacle around the vehicle; and a control section to calculate a risk potential for the vehicle in accordance with the traveling condition. The control section performs a support control to support the driver in accordance with the risk potential, performs a first assist control to restrain disturbance (such as vibration from a road) transmitted to the driver in accordance with the risk potential, and performs a second assist control to produce inducement simulating a condition change (such as a vehicle behavior) attributable to an increase of the risk potential, in accordance with the risk potential. The control section further performs a cooperation control to coordinate the first assist control and the second assist control.
