Abstract
A method for handwheel actuator bind and/or steering column detection includes receiving, in response to a signal indicating a change in position of power steering column, a handwheel torque signal from a sensor associated with a handwheel of a vehicle. The method also includes determining whether a torque value associated with the handwheel torque signal is greater than a threshold. The method also includes, in response to a determination that the torque value associated with the handwheel torque signal is greater than the threshold, initiating at least one countermeasure.
Claims20
A method for handwheel actuator bind and/or steering column detection, the method comprising:
- receiving a handwheel torque signal from a sensor associated with a handwheel of a vehicle, in response to a signal indicating a change in position of power steering column associated with one of a telescoping movement of the power steering column, a raking movement of the power steering column, and a tilting movement of the power steering column;
- determining whether a torque value associated with the handwheel torque signal is greater than a threshold;
- and
- in response to a determination that the torque value associated with the handwheel torque signal is greater than the threshold, initiating at least one countermeasure.
A system for handwheel actuator bind and/or steering column detection, the system comprising:
- a processor;
- and
- a memory including instructions that, when executed by the processor, cause the processor to:
- receive a handwheel torque signal from a sensor associated with a handwheel of a vehicle, in response to a signal indicating a change in position of power steering column associated with one of a telescoping movement of the power steering column, a making movement of the power steering column, and a tilting movement of the power steering column;
- determine whether a torque value associated with the handwheel torque signal is greater than a threshold;
- and
- in response to a determination that the torque value associated with the handwheel torque signal is greater than the threshold, initiate at least one countermeasure.
An apparatus for handwheel actuator bind and/or steering column detection, the apparatus comprising:
- a controller configured to:
- receive a handwheel torque signal from a sensor associated with a handwheel of a vehicle, in response to a signal indicating a change in position of power steering column of a steer-by-wire steering system, wherein the change in position of the power steering column is associated with one of a telescoping movement of the power steering column, a raking movement of the power steering column, and a tilting movement of the power steering column;
- determine whether a torque value associated with the handwheel torque signal is greater than a threshold indicating that the power steering column encountered an obstacle;
- and
- in response to a determination that the torque value associated with the handwheel torque signal is greater than the threshold, initiate at least one countermeasure.
