摘要： An assist control unit calculates an assist torque command based on a steering torque. A steering angle control unit calculates a steering angle control torque command so that a steering angle determined according to an output of a motor follows a target steering angle commanded from a lane keeping support device. A vibration application control unit calculates a lane departure warning control torque command to apply vibration to an assist torque when a lane departure warning activation request is notified. A motor drive control unit controls a drive of the motor based on an addition value of the assist torque command, the steering angle control torque command, and the lane departure warning control torque command. The steering angle control unit includes a vibration removal filter configured to remove vibration frequency components of the lane departure warning device in calculations on a steering angle signal loop for steering angle control.

摘要： A method for determining an as-driven path of an agricultural work vehicle includes receiving position data indicative of a position of the agricultural work vehicle in a field during a first pass of the agricultural work vehicle in the field, receiving inertial movement data of the agricultural work vehicle during the first pass, and receiving operational data indicative of at least one of a steering angle of a wheel of the agricultural work vehicle, a wheel speed of the wheel of the agricultural work vehicle, or a transmission speed of the agricultural work vehicle during the first pass. Moreover, the method includes generating an as-driven path of the agricultural work vehicle during the first pass based at least in part on the position data, the inertial movement data, and the operational data. Additionally, the method includes performing a control action based on the as-driven path.

摘要： The present embodiments may provide a steer-by-wire steering device that may enhance the driver's driving feel and increase the driver's steering stability and convenience in manual driving mode and autonomous driving mode by stopping the steering wheel from further mechanical rotation when the wheel rotation reaches a maximum point.

摘要： Methods and apparatus to control a torque threshold for hands on/off detection are disclosed. An example non-transitory machine readable storage medium includes instructions to cause programmable circuitry to at least identify a velocity of a steering rack or an angular velocity associated with a steering wheel, cause a first torque threshold associated with a first rotational direction of the steering wheel to be different from a second torque threshold associated with a second rotational direction of the steering wheel when the velocity or the angular velocity satisfies a threshold, identify a steering torque encountered by the steering wheel, and detect a hands off condition when the steering torque does not satisfy the first torque threshold nor the second torque threshold.

摘要： Vehicle control apparatus includes: external environment sensor configured to detect external environment situation including location of object in surrounding area of vehicle; and electronic control unit including processor and memory coupled to processor. The electronic control unit: recognizes external environment situation of vehicle based on signal from external environment sensor; calculates target steering angular velocity of steering assistance of vehicle based on external environment situation recognized; limits steering assistance by decreasing target steering angular velocity to limited steering angular velocity when duration exceeds predetermined duration, duration being period while target steering angular velocity calculated exceeds predetermined steering angular velocity; and limits steering assistance so that change amount of steering angle of vehicle from start of steering assistance is equal to or smaller than predetermined value.

摘要： A travel control device for a vehicle includes an object information acquisition device, an automatic steering device, and an electronic control unit. The electronic control unit is configured to gradually decrease a target correction quantity of a steering angle when the electronic control unit determines that travel control needs to be ended. The electronic control unit is configured to change a degree of decrease of the target correction quantity to different degrees based on a magnitude relationship between a target control quantity and an actual control quantity closest to a time point at which it is determined that the travel control needs to be ended.

摘要： A crop row detection system includes a camera mounted to an agricultural machine to image a ground surface traveled by the agricultural machine to acquire time-series color images including at least a portion of the ground surface, and a processor configured or programmed to (i) perform image processing for the time-series color images, (ii) generate, from the time-series color images, an enhanced image in which a color of a crop row for detection is enhanced to provide an enhanced image, (iii) generate from the enhanced image a plan view image as viewed from above the ground surface, the plan view image being classified into first pixels having a color index value for the crop row equal to or greater than a threshold and second pixels having the color index value below the threshold, and (iv) determine positions of edge lines of the crop row based on the color index values of the first pixels.

摘要： A vehicle maneuvering scenario can be identified based on data from vehicle sensors including at least one of (a) a location of the vehicle, or (b) data indicating that a first steering wheel rotation in a first direction and a second steering wheel rotation in a second direction each exceed a rotation threshold. A steering ratio can be determined based on the vehicle maneuvering scenario. Vehicle steering can then be actuated according to the steering ratio.
