20220402542 · 2022-12-22 ·

A steering-angle control apparatus controls a steering mechanism based on a state command value, which is input in each predetermined period. An interpolation unit interpolates between a previous value and a current value of the input state command value to compute a state interpolation value in an interpolation period, which is shorter than the predetermined period. An interpolation-value determination unit determines whether the state interpolation value is an abnormal value. A control unit controls the steering mechanism based on the state interpolation value computed by the interpolation unit when the interpolation-value determination unit determines that the state interpolation value is not an abnormal value, and controls the steering mechanism based on the current value of the state command value when the interpolation-value determination unit determines that the state interpolation value is an abnormal value.

Calculating velocity of an autonomous vehicle using radar technology
11531353 · 2022-12-20 · ·

Examples relating to vehicle velocity calculation using radar technology are described. An example method performed by a computing system may involve, while a vehicle is moving on a road, receiving, from two or more radar sensors mounted at different locations on the vehicle, radar data representative of an environment of the vehicle. The method may involve, based on the data, detecting at least one scatterer in the environment. The method may involve making a determination of a likelihood that the at least one scatterer is stationary with respect to the vehicle. The method may involve, based on the determination being that the likelihood is at least equal to a predefined confidence threshold, calculating a velocity of the vehicle based on the data from the sensors. The calculated velocity may include an angular and linear velocity. Further, the method may involve controlling the vehicle based on the calculated velocity.

Vehicle control system

A vehicle control system installed on a vehicle includes: an automatic steering control device configured to execute automatic steering control that determines a steering angle command value and controls steering of the vehicle such that an actual steering angle follows the steering angle command value; a stop state detection device configured to detect a stop state where the vehicle is stopped; and an override detection device configured to detect an override operation by a driver of the vehicle. When the override operation is detected in the stop state, the automatic steering control device prohibits variation in the actual steering angle due to the automatic steering control, until the vehicle starts moving.

Vehicle Guidance System and Method for Terminating Automated Vehicle Guidance

A vehicle guidance system detects when a driver of the vehicle manually intervenes in the longitudinal and/or transverse guidance of the vehicle while the vehicle is being operated in an automated driving mode. The vehicle guidance system outputs an indication to the driver via a user interface of the vehicle prompting the driver to take over the longitudinal and/or transverse guidance of the vehicle. The vehicle guidance system also continues to provide the longitudinal and/or lateral guidance of the vehicle in at least a partially automated manner for a takeover period of time and/or for a takeover distance.

VEHICLE STEERING CONTROL DEVICE

A vehicle steering control device includes a control device. The control device is configured to control a steering reaction force to be applied to a steering operation performed by a driver of a driver's vehicle, acquire information on a curved road ahead of the driver's vehicle in a traveling direction, set a guide steering operation amount based on the information on the curved road, predict a time at which the driver starts an actual steering operation for driving the driver's vehicle along the curved road as a steering operation start time, and set, based on a difference between the guide steering operation amount and an actual amount of the steering operation, the steering reaction force at a time earlier by a predetermined period than the steering operation start time.
