System, methods, and other embodiments described herein relate to dynamically determining an appropriate responsive action for a moving vehicle in accordance with local traffic regulations. In one embodiment, the disclosed system identifies a stationary vehicle in an environment of the subject vehicle based at least in part on information from a plurality of sensors disposed on the subject vehicle and classifies a type of the stationary vehicle as valid or abandoned based at least in part on the information from the plurality of sensors. A classification of valid indicates that a traffic regulation requires the subject vehicle to undertake a responsive action toward the stationary vehicle. The disclosed system obtains a local traffic regulation based on a location of the subject vehicle and modifies a trajectory of the subject vehicle based on the local traffic regulation when the type of the stationary vehicle is determined to be valid.

Systems and methods for addressing a moving vehicle response to a stationary vehicle

In one embodiment, example systems and methods related to vehicle platooning are provided. Vehicles are equipped with a vehicle platooning system that allows the vehicles to exchange messages related to vehicle platooning. When a following vehicle desires to follow a leading vehicle, the following vehicle sends a request to the leading vehicle, and the leading vehicle sends the following vehicle information such as its current speed. The following vehicle may then use the information, along with sensor data such as images of the rear of the leading vehicle, to follow the leading vehicle from a following distance. When the leading vehicle desires to change lanes, the leading vehicle sends a message to the following vehicle to determine if the following vehicle is able to change lanes. If the following vehicle determines that it can change lanes (i.e., the lane is clear from other vehicles or objects), the following vehicle can send a message to the leading vehicle indicating that it can change lanes. The leading and following vehicles may then change lanes at approximately the same time.

A backup assistance system for a vehicle. The system includes a backup control module configured to restrict at least one of vehicle backup speed, acceleration, and jerk when a field of view of one or more backup sensors is restricted.

Vehicle backup assistance system

A vehicle control device mounted on the own vehicle and configured to control the own vehicle according to the position of another vehicle ahead of the own vehicle. The vehicle control device comprises an estimated course calculation means calculating an estimated course of the own vehicle; a setting means setting a parameter indicating whether the other vehicle is in the path of the own vehicle based on the relative position of the other vehicle with respect to the own vehicle in a lateral direction orthogonal to the estimated course of the own vehicle; a determination means determining whether the other vehicle is a leading vehicle in the path of the own vehicle based on the parameter; and a changing means changing the likelihood of being determined as the leading vehicle when the estimated course is a curve, based on the estimated course and the position of the other vehicle.

Vehicle control device and vehicle control method

In an inter-vehicle control apparatus, a controller performs acceleration control of an own vehicle, based on an actual inter-vehicle physical quantity and a target inter-vehicle physical quantity. A limiter sets a limit value for a target jerk during the acceleration control. A detector detects an occurrence of at least one of: an event in which the inter-vehicle distance becomes discontinuously shorter; and an event in which a target inter-vehicle distance corresponding to the target inter-vehicle physical quantity becomes discontinuously longer. A determiner determines a risk of collision with the preceding vehicle, based on an operation state of the preceding vehicle in relation to the own vehicle. When at least one of the events is detected, the limiter sets the limit value to a value based on the risk of collision such that change in deceleration of the own vehicle is kept lower as the risk of collision decreases.

Inter-vehicle control apparatus

A vehicle driving control apparatus is provided for controlling an own vehicle to track a target vehicle. The vehicle driving control apparatus includes: (1) means for acquiring an actual relative speed of the target vehicle to the own vehicle; (2) means for setting a target acceleration of the own vehicle based on the product of a relative speed gain and the actual relative speed acquired by the acquiring means, the relative speed gain being normally set to a reference gain; (3) means for detecting occurrence of an event which causes the target acceleration set by the setting means to discontinuously change; and (4) means for correcting, upon detection of occurrence of the event by the detecting means, the relative speed gain so as to gradually increase the relative speed gain from a value that is less than the reference gain.

Vehicle driving control apparatus

A preceding vehicle selection apparatus estimates a curvature of a road on which an own vehicle is traveling, detects an object ahead of the own vehicle, and determines a relative position in relation to the own vehicle. Based on the curvature and the relative position, an own vehicle lane probability instantaneous value is determined. This instantaneous value is a probability of the object ahead being present in the same vehicle lane as the own vehicle. By a filter calculation on the instantaneous value, an own vehicle lane probability is determined. Based on the own vehicle lane probability, a preceding vehicle is selected. An inter-vehicle time required for the own vehicle to reach a detection position of the object ahead is calculated. Based on the inter-vehicle time, characteristics of the filter calculation are changed such that an effect of the own vehicle lane instantaneous value increases as the inter-vehicle time decreases.

Preceding vehicle selection apparatus

A preceding vehicle selection apparatus estimates a curvature of a traveling road on which an own vehicle is traveling, detects an object ahead of the own vehicle, and determines a relative position in relation to the own vehicle, for each object ahead. Based on the estimated curvature and the determined relative position, an own vehicle lane probability instantaneous value for each object ahead is repeatedly determined. An own vehicle lane probability is determined by performing a filter calculation on the calculated own vehicle lane probability instantaneous value. Based on the determined own vehicle lane probability, a preceding vehicle is selected. Characteristics of the filter calculation are set such that an object ahead associated with a preceding vehicle selected in a previous processing cycle is relatively less affected by the own vehicle lane probability instantaneous value than an object ahead associated with an object other than the preceding vehicle.

In a preceding vehicle selection apparatus, for each object ahead, a relative position, a relative speed, and width information indicating a lateral width are determined. A lateral position of the object ahead with reference to a traveling direction of the own vehicle is corrected by using the width information of the object ahead. Based on the relative position of the object ahead of, which the lateral position has been corrected, an own vehicle lane probability is calculated for each object ahead. A preceding vehicle is selected from the objects ahead based on the calculated own vehicle lane probability. Based on a value of a correlated parameter that has correlation with error in the lateral position or error in the width information, a correction amount of the lateral position is reduced as error in the lateral position or error in the width information becomes large.

When a vehicle runs along a curved path, successive values of a speed limit are calculated based on the yaw rate of the vehicle, and values of acceleration demand are calculated and applied to control the actual vehicle speed based on the speed limit. If commencement of oscillation of the yaw rate and acceleration demand is detected, due to running along the curved path, guard processing is applied to the values of speed limit used to calculate the acceleration demand or is applied to the acceleration demand, such as to prevent the acceleration demand from varying in a direction that would increase the speed limit. Instability of deceleration control due to the oscillation is thereby substantially suppressed.
