Abstract
An electronic control unit configured to control at least one motor used to reposition a seat assembly within an automotive vehicle. The electronic control unit comprises a mode manager configured to reposition the seat assembly from a first position to a second position and a performance evaluation module configured to monitor the repositioning of the seat assembly. The performance evaluation module detects and compensates for abrupt stops in the at least one motor.
Claims23
An electronic control unit configured to adapt to changes in operation of a seat assembly within an automotive vehicle, the electronic control unit comprising:
- a mode manager configured to;
- receive a request to reposition the seat assembly;
- and
- control at least one motor to reposition the seat assembly;
- and
- a performance evaluation module configured to:
- monitor operation of the at least one motor as the motor repositions the seat assembly;
- determine a smoothness with which the at least one motor stops;
- determine if the smoothness is abrupt;
- and
- if the performance evaluation module determines that the smoothness is abrupt, the performance evaluation module is configured to adjust the at least one motor to compensate for the abrupt motor stop before the mode manager receives another request to reposition the seat assembly.
A method for controlling operation of a seat assembly in an automotive vehicle, the method comprising the steps of:
- monitoring operation of at least one motor while the at least one motor repositions the seat assembly;
- determining an impact on the at least one motor when the motor stops after repositioning the seat assembly;
- determining if the impact increases over time;
- and
- if it is determined that the impact increases over time, adjusting the at least one motor to compensate for the increase in impact.
An electronic control unit configured to adapt to changes in operation of a seat assembly within an automotive vehicle, the electronic control unit comprising:
- a mode manager configured to reposition the seat assembly from an initial position to a final position;
- and
- a performance evaluation module configured to:
- monitor movement of at least one motor while the at least one motor repositions the seat assembly from an initial position to a final position;
- monitor an amount of friction encountered by the at least one motor as the motor repositions the seat assembly;
- determine if the amount of friction increases as the at least one motor repositions the seat assembly;
- and
- if the performance evaluation module determines that the amount of friction increases, the performance evaluation module is configured to adjust the motor to overcome the increased friction in the movement of the at least one motor.
