Techniques for determining gaps for performing lane change operations are described. A first region in an environment of a vehicle can be determined. The first region can be associated with a first time period through which the vehicle is unable to travel and can correspond to a constraint space. A second region of the environment can be determined. The second region can be associated with a second time period and can correspond to a configuration space. A gap in the environment can be determined based on a portion of the configuration space that is exclusive of the constraint space. A trajectory can be determined based on the gap. The trajectory can be associated with performing a lane change operation and can be associated with a cost. The vehicle can be controlled to perform the lane change operation based at least in part on the trajectory and the cost.

A swerve assist to assist the driver of a transportation vehicle during an avoidance maneuver so that a collision with an obstacle is avoided. An additional steering torque for amplifying a current steering torque is applied when an avoidance maneuver of the transportation vehicle is detected. A single-wheel braking of the transportation vehicle is actuated to increase a transverse offset of the transportation vehicle.

Techniques described herein relate to lane handling, for instance to enable vehicles to perform turns without colliding into oncoming vehicles and/or bicycles in other lanes. System(s) associated with a vehicle can access sensor data and/or map data associated with an environment within which the vehicle is positioned in a first lane. The system(s) can determine that the vehicle is to perform a turn and a start of a second lane associated with the turn or a merging zone associated with the second lane. The system(s) can determine a location of the vehicle relative to the start of the second lane or the merging zone associated with the second lane and, based partly on the location, can cause the vehicle to merge into the second lane prior to performing the turn.

An embodiment apparatus for assisting driving of a vehicle on a spiral ramp includes a spiral ramp determining module configured to determine whether a vehicle travels on a spiral ramp that guides rotation of the vehicle in a specific direction, by using an image of the spiral ramp acquired by a camera included in the vehicle, and a side mirror control module configured to automatically lower a side mirror installed on a side of the vehicle to which the vehicle rotates to an angle to show a view of a rear wheel in response to a determination that the vehicle travels on the spiral ramp.

A method of determining an allowable vehicle state space of an articulated vehicle (1) for safely completing a maneuver, wherein the vehicle state space comprises vehicle velocity, the method comprising; monitoring a drivable area (31) ahead of the articulated vehicle (1), predicting a potentially swept area (33) ahead of the articulated vehicle (1), wherein the potentially swept area (33) represents an area that may be traversed by the articulated vehicle (1) during the maneuver with a probability, based on an initial vehicle state of the articulated vehicle (1), a geometry of the articulated vehicle (1), and on error characteristics associated with one or more sensor input signals used for positioning the articulated vehicle (1), and determining the allowable vehicle state space such that the predicted potentially swept area (33) does not extend beyond the drivable area (31) ahead of the vehicle (1).

A first risk potential field for a risk avoidance control is a sum of a risk potential field in which a valley of a risk value extends in a lane longitudinal direction and a risk potential field in which the risk value is maximum at a position of an object and decreases as a distance from the object increases. The steering control is executed such that a vehicle approaches a first minimum point that is a minimum point of the first risk potential field and that is searched for in a first search range. When a plurality of first minimum point candidates is present in the first search range, the first minimum point candidate that is present in a direction away from a foremost object as viewed from a previous minimum point and is the closest to the previous minimum point is selected as the current first minimum point.

Provided are a steering control system and method. The steering control system includes a control unit configured to perform steering control using a steering torque and a steering angle detected by a steering torque sensor and a steering angle sensor of a vehicle, wherein the control unit performs the steering control in consideration that the steering torque or the steering angle is changeable by a disturbance.

A system includes a processor and a memory in communication with the processor. The memory has a human-machine interface module having instructions that, when executed by the processor, cause the processor to identify, based on sensor data regarding a vehicle and an environment in which the vehicle operates, an event in which the vehicle should perform an autonomous steering maneuver determined by an autonomous driving system. The instructions further cause the processor to, in response to identifying the event, decouple control of a steering rack of the vehicle by a handwheel of the vehicle and reduce a rational movement of the handwheel from a normal range to a restricted range, and determine, by the autonomous driving system, the autonomous steering maneuver to be performed by the vehicle influenced by an angle of the handwheel detected by the processor when the rotational movement of the handwheel is in the restricted range.

The instructions further cause the processor to determine, by the autonomous driving system, the autonomous steering maneuver to be performed by the vehicle influenced by an isometric torque input applied to the handwheel and detected by the processor when the handwheel is locked.

A driving evaluation system includes an approach determiner configured to determine whether a degree of approach between an object present in a periphery of a vehicle and the vehicle is a predetermined degree or more, a relative position acquirer configured to acquire a relative position of the vehicle with respect to a traveling lane along which the vehicle travels, and an evaluator configured to refer to the relative position acquired by the relative position acquirer and thereby evaluate a driver's skill in driving the vehicle as higher as the vehicle travels at a position closer to a center of the traveling lane, the evaluator excluding an interval in which it is determined by the approach determiner that the degree of approach is a predetermined degree or more from a target for evaluation.
