VEHICLE CONTROL DEVICE, VEHICLE CONTROL METHOD AND VEHICLE CONTROL PROGRAM
A vehicle control device includes a setting part that sets a target area which is an area used as a target when the host vehicle changes lane, a derivation part that derives a first time period which is a time length required from a start to a termination of a lane change by the host vehicle, and a second time period which is a time length required for a following reference vehicle, traveling at rear of the target area, to catch up with a preceding vehicle traveling in front of the host vehicle, a determination part that determines that the lane change by the host vehicle is possible, in a case at least a condition in which that the first time period is longer than the second time period is satisfied, and a controller that performs the lane change of the host vehicle.
Movement route generating apparatus and movement route generating method
A movement route generating apparatus includes an angle calculating unit calculating an angle formed by a vehicle travel direction at a target position compared with that at the current position, a graph generating unit generating a graph that has most gentle inclinations by plotting the curvature of a travel trajectory matching the steering angle of the vehicle and a distance traveled on two axes, under the condition that the area of a graph generated in correspondence to a travel trajectory from the current position to the target position is equal to the angle and other conditions, and a route setting unit setting a travel trajectory represented by the graph as the movement route of the vehicle. Accordingly, a travel trajectory with the smallest degree of change in curvature per unit distance traveled, that is, a low horizontal angular velocity caused by vehicle steering, can be set as a movement route.
Inertial reference for TBA speed limiting
A method of controlling a vehicle while the vehicle is backing up with a trailer attached thereto. The vehicle may include a brake system and a power train system. The method includes determining a trailer yaw rate, and estimating a modified trailer curvature. The modified trailer curvature comprises a ratio of the trailer yaw rate to the vehicle speed. The method further includes determining a maximum allowable vehicle speed as a function of modified trailer curvature utilizing predefined criteria that defines a maximum allowable vehicle speed for a given modified trailer curvature. The method further includes limiting the vehicle speed such that the maximum allowable vehicle speed is not exceeded.
Method and device for operating a vehicle
A method for operating a vehicle, including the following: detection of a vehicle environment; detection of a steering angle for a vehicle wheel that is defined by a steering device; ascertainment of a collision probability for the vehicle based on the detected vehicle environment and the detected steering angle in the case of an unchanged steering angle; correction of the steering angle if the ascertained collision probability is greater than or equal to a predetermined collision probability threshold in order to prevent a collision. Also described is a device for operating a vehicle and a computer program.
CONTROL DEVICE FOR VEHICLE AND CONTROL METHOD OF VEHICLE
A control device includes an electronic control unit configured to expand a first detection range at least in front of a host vehicle during execution of current first steering control, determine whether next first steering control is needed to be implemented and whether a relative direction of a next second object with respect to the host vehicle is the same as a relative direction of a first object with respect to the host vehicle when the second object is detected, and perform relaxation steering control based on a target value smaller in absolute value than a return target value after an end of the current first steering control when the implementation of the next first steering control is determined to be needed and the relative directions with respect to the host vehicle are determined to be the same between the second and the first object.
Selectively deployable control device
A vehicle (100) comprises a docking port and a selectively demountable switch (10) having a body and a rotary knob (40) on the body, and an interface between the switch and the docking port to enable commands entered by operation of the rotary knob to be communicated to the vehicle (100). The vehicle (100) incorporates a tow-assist system to facilitate reversing of a trailer, the vehicle (100) being of the type having a positive power-assisted steering mechanism (350) for its steerable wheels (250). The system comprises computing means (310) and the demountable switch (10). The computing means (350) is arranged to interpret rotational movement of the knob (40) on the body as desired steering movements of the trailer when the vehicle (100) is being reversed and to effect steering commands for the positive power assisted steering mechanism (350) to achieve said desired steering movements of the trailer.
Vehicle Control Device and Method
The present invention provides a vehicle control device and method capable of ensuring steering accuracy. In a vehicle provided with a left-right pair of steered wheels for which the braking/driving forces can each be controlled, and a steering force generation device that generates steering force for the steered wheels and controls the steering angle of the steered wheels, this vehicle control device and method control the steering force and the steering reaction force from the steering force generation device by controlling the braking/driving force of each of the steered wheels on the basis of the lateral force acting on the steered wheels.
Service Brake Assist Steering
A brake assist system is disclosed for assisting the steering operations of a mobile vehicle. The brake assist system comprises a service brake assembly having a first brake device and a second brake device and an auxiliary control assembly coupled to the service brake assembly. An electronic control unit is communicatively coupled to the auxiliary control assembly and configured to receive an input signal indicative of a vehicle operating parameter comprising at least one of a steering angle generated by a vehicle guidance system or a vehicle speed error and generates a control signal to activate the main and secondary valve circuits by proportionally controlling an output of at least two control valves arranged in the main and secondary valve circuits to supply a pressurized flow of fluid is applied to at least one of the first or second brake devices to assist steering operations of the vehicle.
STRATEGY MODES FOR AUTONOMOUS VEHICLE OPERATIONS
Systems and methods for operating autonomous vehicles are described. An autonomous vehicle may detect strategy modes and/or actions of other vehicles in a local environment. The autonomous vehicle may then select a strategy mode for its operations based on the detected strategy modes and/or actions of other vehicles, and based on an operational goal for the autonomous vehicle. The strategy modes may include an uncoupled strategy mode, a permissive strategy mode, an assistive strategy mode, and a preventative strategy mode. The autonomous vehicle may further select an action for its operations based on the selected strategy mode.
DETERMINATION OF STRATEGY MODES FOR AUTONOMOUS VEHICLE OPERATIONS
Systems and methods for determining strategy modes for autonomous vehicles are described. An autonomous vehicle may detect aspects of other vehicles and aspects of the environment using one or more sensors. The autonomous vehicle may then determine strategy modes of the other vehicles, and select a strategy mode for its own operation based on the determined strategy modes and an operational goal for the autonomous vehicle. The strategy modes may include an uncoupled strategy mode, a permissive strategy mode, an assistive strategy mode, and a preventative strategy mode. The autonomous vehicle may further determine elements in the environment and topological constraints associated with the environment, and select the strategy mode for its own operation based thereon.
