Vehicle Control Device, Vehicle Control Method, and Vehicle Control System
A vehicle control device, a vehicle control method, and a vehicle control system according to the present invention perform feedback control to reduce difference in lateral direction or difference in turning direction between an own vehicle and a travel target, so as to acquire a first steering angle control conunand for increasing a steering angle control amount as the velocity of the own vehicle decreases, acquire a second steering angle control command for decreasing the steering angle control amount with respect to the velocity, compared with a magnitude of the steering angle control amount with respect to the velocity obtained by the first steering angle control command, output the first steering angle control command when the velocity is greater than a predetermined threshold, and output the second steering angle control command when the velocity is equal to, or less than, the predetermined threshold.
MOVING BODY CONTROL APPARATUS, MOVING BODY, AND MOVING BODY CONTROL METHOD
A moving body control apparatus includes a cancel control section performing control to cancel a lane change when a first cancel condition and a second cancel condition for cancelling the lane change are satisfied. When the first cancel condition is satisfied with the grip of an occupant on a manipulator being a prescribed level or greater, if a distance in a vehicle width direction between a moving body and a lane marker is a first distance threshold value or greater, the cancel control section judges that the second cancel condition is satisfied and cancels the lane change, and when the first cancel condition is satisfied with the grip being less than the prescribed level, if the distance is not less than a second distance threshold value greater than the first distance threshold value, the cancel control section judges that the second cancel condition is satisfied and cancels the lane change.
Approach for consolidating observed vehicle trajectories into a single representative trajectory
A method and apparatus is provided for controlling the operation of an autonomous vehicle. According to one aspect, the autonomous vehicle may track the trajectories of other vehicles on a road. Based on the other vehicle's trajectories, the autonomous vehicle may generate a pool of combined trajectories. Subsequently, the autonomous vehicle may select one of the combined trajectories as a representative trajectory. The representative trajectory may be used to change at least one of the speed or direction of the autonomous vehicle.
Vehicle control apparatus, vehicle, and control method
The present invention provides a vehicle control apparatus for performing traveling control of a vehicle, the apparatus comprising: a detection unit configured to detect a peripheral status of the vehicle; a determination unit configured to determine, based on a detection result of the detection unit, whether a preceding vehicle exhibits a predetermined behavior in a vehicle width direction; and a control unit configured to perform steering control of the vehicle, wherein steering control modes of the vehicle include a first mode and a second mode, and wherein in a case where the determination unit determines that the preceding vehicle exhibits the predetermined behavior during the steering control of the vehicle in the first mode, the control unit changes from the first mode to the second mode and performs the steering control of the vehicle in the second mode.
Vehicle control system
A vehicle control system includes: a turning device that turns a wheel of a vehicle; a steering sensor that detects a driver's steering operation; and a control device configured to execute automated turning control that controls the turning device to automatically turn the wheel, independently of the driver's steering operation. A modification desire degree represents a degree to which the driver's steering operation modifies vehicle travel caused by the automated turning control. During execution of the automated turning control, the control device calculates the modification desire degree based on a result of detection by the steering sensor. When the modification desire degree exceeds a threshold, the control device executes system suppression processing without terminating the automated turning control. In the system suppression processing, the control device weakens the automated turning control as compared to a case where the modification desire degree is equal to or lower than the threshold.
Method for performing a vehicle assist operation
The technology relates to assisting large self-driving vehicles, such as cargo vehicles, as they maneuver towards and/or park at a destination facility. This may include a given vehicle transitioning between different autonomous driving modes. Such a vehicles may be permitted to drive in a fully autonomous mode on certain roadways for the majority of a trip, but may need to change to a partially autonomous mode on other roadways or when entering or leaving a destination facility such as a warehouse, depot or service center. Large vehicles such as cargo truck may have limited room to maneuver in and park at the destination, which may also prevent operation in a fully autonomous mode. Here, information from the destination facility and/or a remote assistance service can be employed to aid in real-time semi-autonomous maneuvering.
Steering wheel angle calibration
A first distance d.sub.1 between a vehicle at a first location and an object is determined. A best fit line representing the object is determined from a plurality of sensor data. A distance Δd to move to a second location is specified. A predicted second distance d.sub.p between the vehicle at the second location and the object is determined based on the first distance d.sub.1, the distance Δd, and the best fit line. The vehicle is operated from the first location to the second location based on a center steering wheel angle. A measured second distance d.sub.2 between the vehicle at the second location and object is determined. Then the center steering wheel angle is one of (a) maintained based on the predicted second distance d.sub.p matching the measured second distance d.sub.2, or (b) updated based on the predicted second distance d.sub.p being different than the measured second distance d.sub.2.
SHARED CONTROL FOR VEHICLES TRAVELLING IN FORMATION
Methods and apparatus for controlling two or more vehicles travelling in formation. Selected vehicles may be fully or partially autonomously controlled; at least one vehicle is partially controlled by a human driver. Information is collected at each vehicle and from the drivers and it is shared with other vehicles and drivers to create a shared world model. Aspects of the shared world model may be presented to the human driver, who may then respond with a control input. Autonomy systems and the drivers on the vehicles then collaborate to make a collective decision to act or not to act and execute any such action in a coordinated manner.
Driving support apparatus
A driving support apparatus for an own vehicle includes a lane keeping assist control unit. When an interrupting vehicle enters ahead of the own vehicle in (i) a situation in which no preceding vehicle is present ahead of the own vehicle, or (ii) a situation in which a preceding vehicle is present ahead of the own vehicle, while a deviation angle formed between a direction of a traveling trajectory of the interrupting vehicle and a traveling direction of the own vehicle is larger than a threshold, the lane keeping assist control unit is configured not to perform a lane keeping assist control based on the traveling trajectory of the interrupting vehicle, and is configured to discard the traveling trajectory of the interrupting vehicle. On and after the deviation angle becomes equal to or smaller than the threshold, the lane keeping assist control unit is configured to perform the lane keeping assist control based on the traveling trajectory of the interrupting vehicle.
System and method for implementing pre-cognition braking and/or avoiding or mitigation risks among platooning vehicles
A system and method for mitigating or avoiding risks due to hazards encountered by platooning vehicles. The system and method involve interrogating, with one or more sensors, a space radially extending from a lead vehicle as the lead vehicle travels over the road surface, perceiving the environment within the space, ascertaining a hazard caused by an object in the space, and causing a following vehicle, operating in a platoon with the lead vehicle, to take a preemptive braking action to avoid or mitigate risks resulting from the hazard caused by the object in the space.
