VEHICLE LANE-CHANGE OPERATIONS
A speed of a target vehicle in a target lane of operation is determined relative to a host vehicle in a host lane of operation. A virtual boundary is determined around the target vehicle based on the speed of the target vehicle. A position in the target lane and outside the virtual boundary is selected based on a) a first cost function for a deviation of a speed of the host vehicle from a requested speed, and b) a second cost function for a frequency of lane changes. Upon determining to move the host vehicle from the host lane to the target lane, the host vehicle is operated to the position in the target lane.
Collision avoidance assisting apparatus
Disclosed is a collision avoidance assisting apparatus which can execute an automatic braking process and an automatic steering process for avoiding collision with an obstacle. When the magnitude of a steering angle exceeds a predetermined threshold, the collision avoidance assisting apparatus determines that a driver has an intention of avoiding the collision by a steering operation and stops the automatic braking process and the automatic steering process. However, in such a case, the automatic braking process and the automatic steering process may be stopped when the steering angle exceeds the threshold as a result of execution of the automatic steering process. In view of this, when both the automatic braking process and the automatic steering process are being executed, the collision avoidance assisting apparatus continues the automatic braking process and the automatic steering process even when the magnitude of the steering angle is greater than the predetermined threshold.
VEHICLE, METHOD OF CONTROLLING VEHICLE, AND VEHICLE CONTROL INTERFACE BOX
An ADS performs processing including setting an initial value of a wheel steer angle command when an autonomous state has been set to an autonomous mode, obtaining a limitation of a rate, setting a wheel steer angle limitation as the wheel steer angle command when magnitude of the initial value is larger than the wheel steer angle limitation, and transmitting the wheel steer angle command.
SYSTEMS AND METHODS FOR CONTROLLING A VEHICLE LOCALIZATION ROUTINE
A method includes obtaining steering data of the vehicle from one or more steering sensors, determining whether the vehicle is operating in one of a turning state and a non-turning state based on the steering data, performing a localization routine based on a first echo set of the 3D data points from among the plurality of 3D data points when the vehicle is operating in the turning state, and performing the localization routine based on a second echo set of the 3D data points from among the plurality of 3D data points when the vehicle is operating in the non-turning state, where a number of the plurality of 3D data points of the first echo set is greater than a number of the plurality of 3D data points of the second echo set.
Driving surface friction estimations using vehicle steering
Systems and methods are provided for generating data indicative of a friction associated with a driving surface, and for using the friction data in association with one or more vehicles. In one example, a computing system can detect a stop associated with a vehicle and initiate a steering action of the vehicle during the stop. The steering action is associated with movement of at least one tire of the vehicle relative to a driving surface. The computing system can obtain operational data associated with the steering action during the stop of the vehicle. The computing system can determine a friction associated with the driving surface based at least in part on the operational data associated with the steering action. The computing system can generate data indicative of the friction associated with the driving surface.
Systematic Approach Towards System Identification Based Yaw Rate Estimation With Low-Cost IMU+GPS Units
Systems and methods for estimating values of dynamic attributes of autonomous vehicles are disclosed. A first vehicle includes an inertial measurement unit (IMU) configured to measure a dynamic attribute (e.g., rate of change of vehicle yaw angle) and correlate the measured attribute with one or more input variables (e.g., values of steering angle commands). The correlated data is used to generate a model that can be used in a second vehicle to predict a dynamic attribute based at least in part on variable values input from the second vehicle. As a result, it is not necessary for the second vehicle to have an IMU.
Display device for vehicle and parking assist system
A display device for a vehicle includes: an image display unit configured to display a direction indicating image that indicates a travel direction of the vehicle; and a control device configured to execute travel control of the vehicle. The direction indicating image is switchable between a first image that indicates a first travel direction of the vehicle and a second image that indicates a second travel direction of the vehicle, the second travel direction being opposite to the first travel direction. In a case where the control device switches the travel direction of the vehicle from the first travel direction to the second travel direction, the image display unit switches the direction indicating image from the first image to the second image based on a vehicle speed of the vehicle, a state of a power transmission device, and a steering state of the vehicle.
Apparatus and method for controlling articulation of articulated vehicle
An apparatus and method for controlling articulation of an articulated vehicle may prevent jackknifing of the articulated vehicle driven backwards. The apparatus includes a hitch angle calculator configured to calculate a desired hitch angle based on a steering angle and a speed of the articulated vehicle, an error calculator configured to calculate an error between the desired hitch angle and an actual hitch angle of the articulated vehicle, a moment generator configured to generate a moment for controlling the articulation of the articulated vehicle based on the error, and an articulation controller configured to control the articulation of the articulated vehicle based on the moment.
METHOD FOR ESTIMATING A LONGITUDINAL FORCE DIFFERENCE ACTING ON STEERED WHEELS
A method for estimating a longitudinal force difference ΔFx acting on steered axle wheels of a vehicle, the method comprising obtaining data from the vehicle related to an applied steering torque M.sub.steer associated with the steered axle wheels, obtaining a scrub radius value r.sub.s associated with the steered axle wheels, and estimating the longitudinal force difference ΔFx, based on the obtained data and on the scrub radius r.sub.s, as proportional to the applied steering torque M.sub.steer and as inversely proportional to the scrub radius r.sub.s.
