Patent Description:
The present invention relates to an apparatus and method for providing a strategy for the maintenance of safety depending on the occurrence of an event.

The statements in this section merely provide background information related to the present invention and may not constitute prior art.

With the development of the auto industry, an autonomous system and a driving assistance system which facilitates partially autonomous driving (hereinafter, for convenience of description, both of autonomous driving and driving assistance are referred to as "autonomous driving") have been developed. The autonomous system may provide a variety of functions, for example, setting speed keeping, vehicle-to-vehicle distance keeping, lane keeping, and a lane change. The autonomous system may perform autonomous driving using various devices such as a sensor for sensing environments outside the vehicle, a sensor for sensing information about the vehicle, a global positioning system (GPS), a detailed map, a driver state monitoring system, a steering actuator, an acceleration/deceleration actuator, a communication circuit, and a control circuit (e.g., an electronic control unit (ECU)). The autonomous system may detect a critical situation and may provide a minimum risk maneuver (MRM) when sensing the critical situation.

The above-mentioned MRM may include, for example, stopping control in a driving lane, stopping control in a shoulder, or the like. When there is no shoulder in a road, the stopping control in the driving lane may put another surrounding vehicle as well as the vehicle in danger. Thus, when there is no space to safely stop, for example, a shoulder in the road, there is a need for providing a strategy for safe stopping control.

The occupant notification display includes: an explanatory image that shows an explanation of a process executed currently; and a progress image that indicates a degree of progress in the automatic evacuation control.

<CIT> discloses a method for safely parking a vehicle, in which it is checked whether an emergency situation is present, and the vehicle is driven by the driver assistance system to a road shoulder upon recognition of an emergency situation. In controlling the driving operation, information is requested from an external database and taken into account by the driver assistance system.

A minimum-risk stop position for the emergency stop of the vehicle is determined from predictive route data of the future route of the motor vehicle, the minimal risk stopping position is approached with the automatic riving mode, and the secured emergency stop maneuver is executed in the minimum risk stop position.

<CIT> discloses a method for generating a signal for transferring a partly or highly automated vehicle into a safe system state at a target site. First, a need to transfer the vehicle into a safe system state is ascertained. A vehicle state is then determined, the vehicle state encompassing the current vehicle position. At least one target site is ascertained. Travel trajectories are ascertained from the current vehicle position to the at least one target site. The travel trajectories are related. One of the travel trajectories is selected based on the rating that has been carried out. A signal is generated on the basis of the selected travel trajectory.

<CIT> discloses a method for safely parking a vehicle, wherein after identifying an emergency situation of the motor vehicle, an emergency stopping position region is selected from a digital map, and the vehicle is parked within the emergency stopping position region by an automatic driving function. The method includes registering the surroundings, determining stationary objects and conditions in the vicinity of the vehicle within the selected emergency stopping position region, checking the conditions in the vicinity of the vehicle and the stationary objects within the emergency stopping position region regarding parking the vehicle in an optimized manner and determining an optimized emergency stopping position within the emergency stopping position region, and parking the vehicle at the optimized emergency stopping position within the emergency stopping position region using the automatic driving function.

<CIT> discloses an environment monitor having a plurality of sensors for detecting predetermined safety risks associated with a plurality of potential destination regions around a vehicle as the vehicle moves over a roadway. The environment monitor selects one of the potential destination regions having a substantially lowest safety risk as a target area. A path determination unit assembles a plurality of plausible paths between the vehicle and the target area, monitors predetermined safety risks associated with the plurality of plausible paths, and selects one of the plausible paths having a substantially lowest safety risk as a target path. An impact detector detects an impact between the vehicle and another object. A stability control is configured to autonomously steer the vehicle onto the target path when the impact is detected.

<CIT> discloses a method for controlling the operation of a fully automatic driver assistance system of a motor vehicle for independent vehicle guidance and motor vehicle. The method involves transferring the motor vehicle from a takeover condition to a safe condition and the driving interference or a request for driver assumption determines plan of action, which contains temporal operational sequence of control commands of vehicle systems.

<CIT> discloses a driver assistance system of a vehicle where the driver assistance system is able to control the vehicle at least partially automatically, a method alerts the driver to retake control of the vehicle from the driver assistance system based on the distance between the current location of the vehicle and an end of the autopilot capable route section: an end of an autopilot route section in a route planned for the vehicle is determined and distance information is determined between a current position of the vehicle and the end of the autopilot route section, and the distance information is compared to a first and a second threshold value, and a first or a second indication is output as a function thereof.

<CIT> discloses a control system that is operable to control a vehicle in an autonomous or semi-autonomous mode includes a processor that processes data captured by a plurality of exterior sensing sensors: when the control system is operating in the autonomous or semi-autonomous mode and responsive to a determination of an upcoming event that requires the system to hand over control of the vehicle to a driver before the vehicle encounters the event, the control determines (i) a total action time until the vehicle encounters the event, (ii) an estimated time for the driver to take over control and (iii) an estimated handling time for the vehicle to be controlled before the vehicle encounters the event. Responsive to the determinations, this control system (i) allows the driver to take over control of the vehicle or (ii) controls the vehicle to slow down and stop the vehicle before the vehicle encounters the event.

<FIG> is a block diagram illustrating a configuration of an apparatus for providing a safety strategy in a vehicle in some forms of the present disclosure.

Referring to <FIG>, an apparatus <NUM> for providing a safety strategy in a vehicle in some forms of the present disclosure may include a sensor <NUM>, a steering device <NUM>, an acceleration device <NUM>, a deceleration device <NUM>, and a control circuit <NUM>. The apparatus <NUM> for providing the safety strategy in <FIG> may be a portion of an autonomous system and may be loaded into the vehicle.

The sensor <NUM> may be configured to sense information about the outside and inside of the vehicle. For example, the sensor <NUM> may be configured to sense information about an external object. The sensor <NUM> may include a radar, a light detection and ranging (LiDAR), a camera, and the like, for sensing an environment outside the vehicle. For another example, the sensor <NUM> may include a wheel speed sensor, a yaw rate sensor, an acceleration sensor, a torque sensor, and the like, for sensing a state of the vehicle.

The steering device <NUM> may be configured to control a steering angle of the vehicle. The steering device <NUM> may include, for example, a steering wheel, an actuator interlocked with the steering wheel, and a controller for controlling the actuator and may be controlled by a driver of the vehicle and/or the autonomous system.

The acceleration device <NUM> may be configured to control acceleration of the vehicle. The acceleration device <NUM> may include, for example, a throttle, an actuator interlocked with the throttle, and a controller for controlling the actuator and may be controlled by the driver and/or the autonomous system.

The deceleration device <NUM> may be configured to control deceleration of the vehicle. The deceleration device <NUM> may include, for example, a brake, an actuator interlocked with the brake, and a controller for controlling the actuator and may be controlled by the driver and/or the autonomous system.

The control circuit <NUM> may be electrically connected with the sensor <NUM>, the steering device <NUM>, the acceleration device <NUM>, and the deceleration device <NUM>. The control circuit <NUM> may control the sensor <NUM>, the steering device <NUM>, the acceleration device <NUM>, and the deceleration device <NUM>, and may perform a variety of data processing and various arithmetic operations. The control circuit <NUM> may be, for example, an electronic control unit (ECU), a micro controller unit (MCU), or a sub-controller, which is loaded into the vehicle.

In some forms of the present disclosure, when a predetermined condition is met, the control circuit <NUM> may initiate a minimum risk maneuver (MRM). For example, after a transition demand (TD) occurs, when control authority is not handed over or when an emergency critical situation is detected, the control circuit <NUM> may execute the MRM. The control circuit <NUM> may perform stopping control or deceleration control according to a predetermined MRM.

In some forms of the present disclosure, the control circuit <NUM> may determine a lateral location of the vehicle based on information obtained by the sensor <NUM> and a location of a driving lane of the vehicle in a road. The control circuit <NUM> may obtain information about an external object using the sensor <NUM>. The control circuit <NUM> may obtain information about whether a lane where the vehicle is located is an nth lane in a road on which the vehicle is traveling. When executing an MRM based on the information, the control circuit <NUM> may determine a target lateral location of the vehicle. For example, the control circuit <NUM> may determine the target lateral location as a location adjacent to a left or right end of the driving lane or the center of the driving lane. The control circuit <NUM> may control the vehicle to move to the determined lateral location while executing the MRM. After moving the vehicle to the determined lateral location, the control circuit <NUM> may perform stopping control or deceleration control.

In some forms of the present disclosure, while the driving lane is neighboring to one end of the road on which the vehicle is traveling, the control circuit <NUM> may control the vehicle to be adjacent to the one end of the road while executing an MRM. When the driving lane is not neighboring to the one end of the road, the control circuit <NUM> may perform a lane change to a lane neighboring to the one end of the road and may control the vehicle to be adjacent to the one end of the road neighboring to the changed lane. For example, the control circuit <NUM> may perform a lane change to a lane close to the driving lane between a lane neighboring to the left end of the road or a lane neighboring to the right end of the road. For another example, the control circuit <NUM> may perform a lane change to a lane capable of being changed within a specified time between the lane neighboring to the left end of the road or the lane neighboring to the right end of the road. For another example, the control circuit <NUM> may perform a lane change to a lane in a predetermined direction between the lane neighboring to the left end of the road or the lane neighboring to the right end of the road. After performing the lane change, the control circuit <NUM> may control the vehicle to be adjacent to the one end of the road.

When a shoulder is not included in the road on which the vehicle is traveling, the vehicle may be stopped as close to a road edge as possible by calculating a distance from an outermost lane to the road edge, without stopping at the lane center. Thus, a remote vehicle may be easy to avoid the stopped vehicle to reduce a risk of collision.

In some forms of the present disclosure, when the driving lane is not neighboring to one end of the road, the control circuit <NUM> may control the vehicle to be located on the center of the driving lane while executing an MRM. For example, when it is impossible to perform a lane change within a specified time (when a risk of collision is high upon a lane change), the control circuit <NUM> may control the vehicle to be located on the center of the driving lane without performing the lane change.

In some forms of the present disclosure, when a shoulder is included in the road, the control circuit <NUM> may control the vehicle to move to the shoulder while executing an MRM. For example, when it is possible to perform a lane change to the shoulder within a specified time (when there is no risk of collision upon a lane change), the control circuit <NUM> may control the vehicle to move to the shoulder. After the vehicle moves to the shoulder, the control circuit <NUM> may perform stopping control or deceleration control.

Referring to <FIG>, the apparatus for providing the safety strategy in some forms of the present disclosure may include an external situation recognizing device <NUM>, a driving risk determining device <NUM>, a transition demand (TD) device <NUM>, an MRM determining device <NUM>, an MRM path generator <NUM>, a driving controller <NUM>, and a display controller <NUM>. The apparatus for providing the safety strategy may determine a driving risk situation and may provide an MRM suitable for the situation.

The external situation recognizing device <NUM> may obtain information (e.g., a location, a speed, acceleration, an expected trajectory, and the like) about a static object, such as a structure, a guiderail, and a stopped object, and a moving object, such as an external vehicle, using a sensor <NUM>. The external situation recognizing device <NUM> may obtain information about a road on which the vehicle is currently traveling (e.g., a type of the road, whether there is a shoulder, and the like), based on a map database (DB) <NUM>.

The driving risk determining device <NUM> may expect a probability of collision with the static object or the moving object and a departure from an operational design domain (ODD) of autonomous control. The driving risk determining device <NUM> may recognize an event (e.g., a collision with the static object, a collision with the moving object, a departure from the ODD, or the like) based on the expectation and may predict a time when the event occurs, a location where the event occurs, and the like.

The TD device <NUM> may provide a TD to a driver of the vehicle. The TD may be changed according to a type of the event and over a time remaining until the event occurs. For example, a type of the TD (e.g., a visual notification, an audible notification, an emergency call, and the like) may be changed, and strength of the TD may be adjusted.

The MRM determining device <NUM> may determine an MRM suitable for a current situation. The MRM may include constant-speed driving after deceleration, stopping in a driving lane, stopping after a lane change, and the like. The MRM determining device <NUM> may select an MRM suitable for the current situation among various types of MRMs. When the constant-speed driving is selected, the MRM determining device <NUM> may calculate a final speed. For example, the MRM determining device <NUM> may determine whether the detected event is an event capable of performing low-speed driving (e.g., a departure from an ODD, or the like). When the detected event is the event capable of performing the low-speed driving, the MRM determining device <NUM> may select a strategy for constant-speed driving after deceleration. When there is a shoulder in a road on which the vehicle is traveling, the MRM determining device <NUM> may determine whether it is possible to perform a lane change to the shoulder. When it is possible to perform the lane change to the shoulder, the MRM determining device <NUM> may select a strategy for stopping in the shoulder. When there is no shoulder in the road, the MRM determining device <NUM> may select a strategy for stopping in a lane. When there is no shoulder in the road, the MRM determining device <NUM> may select the strategy for stopping in the lane and may control the vehicle to stop on a location adjacent to an edge of the road.

The MRM path generator <NUM> may generate a driving path according to the determined MRM. The MRM path generator <NUM> may output a location where the vehicle is traveling, a heading angle of the vehicle, and a speed of the vehicle. For example, when the strategy for stopping in the shoulder is selected, the MRM path generator <NUM> may determine whether it is possible to perform a lane change to the shoulder before an event occurs. When it is possible to perform the lane change to the shoulder, the MRM path generator <NUM> may generate a driving path for stopping after performing the lane change to the shoulder. When it is impossible to perform the lane change to the shoulder, the MRM path generator <NUM> may perform stopping control in a driving lane. For another example, when the strategy for stopping in the lane is selected, the MRM path generator <NUM> may calculate a target lateral location adjacent to a road edge when a current lane is a first lane or a final lane and may generate a driving path for stopping in the target lateral location. When the current lane does not correspond to the first lane or the final lane, the MRM path generator <NUM> may generate a driving path for stopping on the center of a driving lane.

The driving controller <NUM> may control a behavior of the vehicle by operating an actuator285. The driving controller <NUM> may control the vehicle depending on the generated path.

The display controller <NUM> may provide visual information to the driver through a cluster <NUM>.

<FIG> is a drawing illustrating an exemplary operation of an apparatus for providing a safety strategy in a vehicle in some forms of the present disclosure.

Referring to <FIG>, a vehicle <NUM> in some forms of the present disclosure may be traveling on a lane adjacent to a right end of a road. The vehicle <NUM> may perform autonomous control using an autonomous system. While performing the autonomous control, the vehicle <NUM> may detect an event for requiring to hand over control authority. The vehicle <NUM> may request its driver to hand over control authority. When the driver does not take over the control authority, the vehicle <NUM> may initiate an MRM. When the vehicle <NUM> is traveling on the lane adjacent to the right end of the road, it may execute a strategy for stopping on a location adjacent to the right end of the road. For example, the vehicle <NUM> may stop on a location away from the right end of the road at a specified distance TBD. Thus, although the vehicle <NUM> stops, a following vehicle may easily avoid the stopped vehicle <NUM>.

Referring to <FIG>, a vehicle <NUM> in some forms of the present disclosure may calculate a target lateral location dTarget in consideration of a current lateral location dLatOffset of the vehicle <NUM> from the center of a driving lane, a width dLaneWidth of the driving lane, a distance dLine2RoadEdege between a line and a road edge, a width WEgo of the vehicle <NUM>, a safety distance dmargin, and the like. An exemplary equation for calculating the target lateral location dTarget is Equation <NUM> below.

The vehicle <NUM> may calculate a path for moving from the current lateral location dLatOffset to the target lateral location dTarget in a lateral direction. The path may be calculated as, for example, a cubic plane curve which connects the current lateral location dLatOffset with the target lateral location dTarget. The vehicle <NUM> may control itself along the calculated path.

Referring to <FIG>, a vehicle <NUM> in some forms of the present disclosure may be traveling on a lane adjacent to a left end of a road. The vehicle <NUM> may perform autonomous control using an autonomous system. While performing the autonomous control, the vehicle <NUM> may detect an event for requiring to hand over control authority. The vehicle <NUM> may request its driver to hand over control authority. When the driver does not take over the control authority, the vehicle <NUM> may initiate an MRM. When the vehicle <NUM> is traveling on the lane adjacent to the left end of the road, it may execute a strategy for stopping on a location adjacent to the left end of the road. For example, the vehicle <NUM> may stop on a location away from the left end of the road at a specified distance. Meanwhile, the vehicle <NUM> may detect an external object <NUM>. It may be difficult to perform a lane change to a right lane due to the external object <NUM>. Thus, the vehicle <NUM> may execute a strategy for stopping on the location adjacent to the left end of the road without moving to a right end of the road.

Referring to <FIG>, a vehicle <NUM> in some forms of the present disclosure may be traveling on the center of a lane of a road. The vehicle <NUM> may perform autonomous control using its autonomous system. While performing the autonomous control, the vehicle <NUM> may detect an event for requiring to hand over control authority. The vehicle <NUM> may request its driver to hand over control authority. When the driver does not take over the control authority, the vehicle <NUM> may initiate an MRM. When the vehicle <NUM> is traveling on the center of the lane of the road, it may execute a strategy for stopping or decelerating in a driving lane. Meanwhile, the vehicle <NUM> may detect an external object <NUM>. It may be difficult to perform a lane change to a right lane due to the external object <NUM> although there is a shoulder in the lane. Thus, the vehicle <NUM> may execute a strategy for stopping in the driving lane without moving to the right lane.

Referring to <FIG>, a vehicle <NUM> in some forms of the present disclosure may be traveling on a lane adjacent to a right end of a road. The vehicle <NUM> may initiate an MRM. When a road on which the vehicle <NUM> is traveling includes a shoulder, the vehicle <NUM> may execute a strategy for stopping in the shoulder included in the road. For example, the vehicle <NUM> may execute a strategy for performing a lane change to the shoulder and stopping in the shoulder.

Furthermore, in a description of <FIG>, an operation described as being performed by the vehicle may be understood as being controlled by a control circuit <NUM> of the apparatus <NUM> for providing the safety strategy.

Referring to <FIG>, in operation <NUM>, the vehicle may initiate an MRM. For example, while the vehicle performs autonomous control, when an event for control authority transition occurs and when a driver of the vehicle does not take over control authority, the vehicle may execute the MRM.

In operation <NUM>, the vehicle may determine its lateral location based on sensor information and a location of a driving lane of the vehicle in a road. For example, the vehicle may determine a target lateral location of the MRM in consideration of information about an external object, information about the road, and information about its current location. The target lateral location may be, for example, the center of a driving lane, a shoulder, or a location adjacent to a road edge.

In operation <NUM>, while executing the MRM, the vehicle may control itself to move to the determined lateral location. For example, the vehicle may move to the location adjacent to the road edge and may perform stopping or deceleration control. For another example, the vehicle may perform stopping or deceleration control on the center of the lane. For another example, the vehicle may move to the shoulder and may perform stopping or deceleration control.
