[0016] The following discussion is directed to various embodiments of the present disclosure. Although one or more of these embodiments may be preferred, the disclosed embodiments should not be interpreted or otherwise used to limit the scope of the present disclosure (including the claims). In addition, it will be understood by those skilled in the art that the following description has a wide range of applications, and the discussion of any embodiment is only meant as an example of that embodiment, and is not intended to imply that the scope of the present disclosure (including the claims) is limited to that embodiment.
[0017] As described, a vehicle (such as a car, truck, sport utility vehicle, crossover, minivan, boat, airplane, all-terrain vehicle, recreational vehicle, or other suitable form of transportation) typically includes various systems, such as a steering system (which may include an electric power steering (EPS) system, a steer-by-wire (SbW) steering system, a hydraulic steering system, or other suitable steering system) and / or other suitable systems (e.g., such as a braking system, a propulsion system, etc.). These systems of the vehicle typically control various aspects of vehicle steering (e.g., including providing steering assistance to the operator of the vehicle, controlling the steering wheel of the vehicle, etc.), vehicle propulsion, vehicle braking, etc.
[0018] As described, such a vehicle includes a steering system including a steering wheel and a steering column. Increasingly, such a steering column includes a power steering column configured to be positioned in a driving position, a stowed position, and / or other suitable positions. Additionally or alternatively, the steering wheel and / or the power steering column may be selectively adjustable (e.g., including position) when in use and / or when stowed.
[0019] Because such steering wheels and power steering columns are positionable, they are susceptible to pinching, binding, etc. For example, during the positioning process, obstacles such as hands, knees, or other suitable obstacles may be in the path of the steering wheel and / or power steering column and the obstacles may contact the steering wheel and / or power steering column.
[0020] Typically, pinch detection systems rely on a feedback loop of current monitoring of the steering wheel actuator. When the monitored current level to the actuator increases, the data is interpreted and transmitted to the control module to stop the actuator (e.g., or an associated motor) or stop and reverse the direction of motion of the actuator (e.g., using an associated motor). However, such systems may be relatively slow to transmit data, which may delay stopping the motion of the actuator (e.g., or an associated motor) and / or changing the direction of the actuator (e.g., or an associated motor) before an adverse condition occurs. Additionally, such systems may be sensitive to noise, such as grease in a relatively cold environment that may cause a stick-slip phenomenon, which may trigger a false positive (e.g., being identified as a pinch or stick condition when there is no pinch or stick condition).
[0021] Therefore, systems and methods (such as those described herein) configured to use torque detection to provide steering wheel actuator clamping and / or binding detection may be desirable. In some embodiments, the systems and methods described herein may be configured to use sensors (e.g., which may include motion sensors, force sensors, rotation sensors, torque sensors, any other suitable sensors, or combinations thereof) and related sensor data associated with a steering wheel of a vehicle's steering system.
[0022] In some embodiments, the systems and methods described herein may be configured to detect movement (e.g., rotation or other suitable movement) of a steering column associated with a steering wheel caused by contact between the steering wheel and an obstacle or obstacles when an obstacle is encountered, the movement being measured by a sensor associated with the steering wheel. The systems and methods described herein may be configured to trigger a column actuator of the steering column to perform a specific countermeasure in response to detecting movement of the steering column, which may include reversing direction, stopping movement, returning to a starting position, issuing a warning, any other suitable countermeasure, or any combination thereof.
[0023] In some embodiments, the systems and methods described herein may be configured to use the measured movement of the steering wheel to detect obstacles in the path of the steering wheel and / or steering column during telescopic movement, rake movement, tilt movement, etc. of the steering column. The systems and methods described herein may be configured to detect movement of the steering wheel caused by any contact with an obstacle that causes the steering wheel to twitch or move. The systems and methods described herein may be configured to reverse a motor associated with an actuator of the steering column in response to detecting the movement of the steering wheel.
[0024] In some embodiments, the systems and methods described herein may be configured to provide steering wheel actuator and / or steering column stuck detection. The systems and methods described herein may be configured to receive a steering wheel torque signal from a sensor associated with a steering wheel of a vehicle in response to a signal indicating a change in position of a power steering column. The systems and methods described herein may be configured to determine whether a torque value associated with the steering wheel torque signal is greater than a threshold. The systems and methods described herein may be configured to initiate at least one countermeasure in response to determining that the torque value associated with the steering wheel torque signal is greater than the threshold. The countermeasure may include reversing the direction of the power steering column, halting the movement of the power steering column, returning the power steering column to a starting position, providing an indication, any other suitable countermeasure, or any combination thereof.

The vehicle 10 may include more or fewer features than those generally illustrated and / or disclosed herein.
[0032] In some embodiments, the vehicle 10 may include a steering system, such as an EPS system, a steer-by-wire steering system (e.g., which may include or communicate with one or more controllers that control components of the steering system without using a mechanical connection between a steering wheel and the wheels 22 of the vehicle 10), a hydraulic steering system (e.g., which may include a magnetic actuator incorporated into a valve assembly of the hydraulic steering system), or other suitable steering systems.
[0033] The steering system may include an open-loop feedback control system or mechanism, a closed-loop feedback control system or mechanism, or a combination thereof. The steering system may be configured to receive various inputs, including but not limited to steering wheel position, input torque, one or more wheel positions, other suitable inputs or information, or a combination thereof.

[0037] In some embodiments, the controller 100 may be configured to provide steering wheel actuator and / or steering column stuck detection. In response to the signal indicating a change in position of the power steering column, the controller 100 may receive a steering wheel torque signal from a sensor 106 associated with the steering wheel of the vehicle 10. The controller 100 may determine whether the torque value associated with the steering wheel torque signal is greater than a threshold.

The countermeasure may include reversing the direction of the power steering column, stopping the movement of the power steering column, returning the power steering column to a starting position, providing an indication, any other suitable countermeasure, or any combination thereof.
[0038] In some embodiments, the controller 100 may perform the methods described herein. However, the methods described herein as performed by the controller 100 are not meant to be limiting, and any type of software executed on a controller or processor may perform the methods described herein without departing from the scope of the present disclosure. For example, a controller, such as a processor executing software within a computing device, may perform the methods described herein.
[0039] Figure 4 2 is a flow chart generally illustrating a method 200 for detecting a stuck steering wheel actuator and / or steering column according to the principles of the present disclosure.

For example, the controller 100 may receive an indication that a user wishes to reposition and / or stow a power steering column.
[0040] At 204, method 200 causes the power steering column to move. For example, controller 100 of vehicle 10 or another suitable controller may cause the power steering column to move.
[0041] At 206, the method 200 determines whether the steering wheel associated with the power steering column has encountered an obstacle. For example, the controller 100 determines whether the steering wheel has encountered an obstacle. If the controller 100 determines that the steering wheel has encountered an obstacle, the method 200 continues at 210.

For example, controller 100 may control actuation of the power steering column and / or steering wheel to allow the power steering column and / or steering wheel to reach the desired position.
[0043] At 210, in response to the steering wheel contacting the obstacle, the method 200 receives sensor data from a sensor associated with the steering wheel, the sensor data indicating at least one of a motion, force, rotation, and / or torque of the steering wheel. For example, the controller 100 may receive sensor data from a sensor 106 associated with the steering wheel.
[0044] At 212, the method 200 determines whether the sensor data indicates that the value of the sensor data (e.g., indicating motion, force, rotation, and / or torque) is greater than a threshold. For example, the controller 100 may determine whether the value is greater than the threshold. If the controller 100 determines that the value is greater than the threshold, the method 200 continues at 216. Alternatively, if the controller 100 determines that the value is not greater than the threshold, the method 200 continues at 214.
[0045] At 214 , method 200 allows the power steering column and / or steering wheel to continue moving. Method 200 continues at 206 .
[0046] At 216 , method 200 performs a countermeasure on the power steering column and / or steering wheel, the countermeasure comprising reversing direction, stopping movement, returning to a starting position, issuing a warning, at least one of any other suitable countermeasures, and / or combinations thereof. For example, controller 100 may perform the countermeasure.
[0047] Figure 5 is a flow chart generally illustrating an alternative steering wheel actuator sticking and / or steering column detection method 300 according to the principles of the present disclosure. At 302, the method 300 receives a steering wheel torque signal from a sensor associated with a steering wheel of a vehicle in response to a signal indicating a change in position of a power steering column. For example, the controller 100 may receive a steering wheel torque signal from a sensor 106 associated with a steering wheel of the vehicle 10 in response to a signal indicating a change in position of the power steering column.
[0048] At 304 , the method 300 determines whether the torque value associated with the steering wheel torque signal is greater than a threshold. For example, the controller 100 may determine whether the torque value associated with the steering wheel torque signal is greater than a threshold.
[0049] At 306 , the method 300 initiates at least one countermeasure in response to determining that the torque value associated with the steering wheel torque signal is greater than the threshold. For example, in response to determining that the torque value associated with the steering wheel torque signal is greater than the threshold, the controller 100 initiates at least one countermeasure.
