  • Patent number: 11453394
    Abstract: A control unit functionally comprises a first steering-torque application control part which commands a steering actuator of a vehicle to execute application of a steering torque determined by a first steering characteristic CH1 and a second steering-torque application control part which commands the steering actuator of the vehicle to execute application of a steering torque determined by a second steering characteristic CH2. The first steering characteristic CH1 comprises plural characteristics CH1A-CH1J which have different steering torques changing according to a vehicle speed. The characteristics CH1A-CH1J are set according to the vehicle speed such that these gradually change in a manner CH1A?CH1J as the vehicle speed becomes higher. The steering torque applied to the steering wheel is set such that the higher the vehicle speed is, the smaller the steering torque is, as shown by the characteristics CH1A-CH1J.

  • Patent number: 11001257
    Abstract: A control unit functionally comprises a first steering-torque application control part which commands a steering actuator of a vehicle to execute application of a steering torque determined by a first steering characteristic CH1 and a second steering-torque application control part which commands the steering actuator of the vehicle to execute application of a steering torque determined by a second steering characteristic CH2. In a case where the vehicle travels at a curved portion of the lane, the first steering characteristic CH1 is set such that a first steering-force increase part L1 is located further toward an allowed right-end point EGR as a vehicle speed becomes higher and the second steering characteristic CH2 is set such that a magnitude of a torque maintenance part L4 becomes lower as a radius of curvature of the curved portion of the lane becomes smaller, like CH2H-CH2L.

  • Publication number: 20200384999
    Abstract: The present invention provides a vehicle control device for controlling vehicle travel. The vehicle control device includes one or more processors configured to function as: a surrounding vehicle detection part configured to detect a surrounding vehicle traveling around an own vehicle; a road surface condition estimation part configured to estimate a road surface condition; a speed distribution setting part configured to set a speed limit distribution defining a permissible upper limit relative speed, around the surrounding vehicle detected by the surrounding vehicle detection part; and a control part configured to control the speed and/or steering of the own vehicle to satisfy the speed limit distribution, wherein the speed distribution setting part is configured to, when it is estimated by the road surface condition estimation part that the road surface condition causes an increase in the braking distance, lower the permissible upper limit relative speed.

  • Publication number: 20200317192
    Abstract: Provided is a vehicle control device capable of reducing a computational load thereon. The vehicle control device includes: an obstacle detection part; a target traveling course calculation part; a corrected traveling course calculation part; a main control part; a backup control part; and an output adjustment part to output a target steering angle and a target acceleration/deceleration, wherein the corrected traveling course calculation part is configured to set an upper limit of a permissible relative speed with respect to an obstacle, and to calculate the corrected traveling course, based on the upper limit, a given evaluation function, and a given limiting condition, wherein the output adjustment part is configured to output, as the control signal, a target steering angle and a target acceleration/deceleration in a situation where it is unable to calculate any corrected traveling course satisfying the limiting condition.
