Techniques for adjusting vehicle running board position
A motor vehicle according to an exemplary aspect of the present disclosure includes, among other things, a running board assembly including a deck, and a linkage assembly configured to guide movement of the deck. The vehicle further includes a motor configured to move the linkage assembly to adjust a position of the deck, and a sensor configured to obtain information indicative of activity adjacent an exterior of the motor vehicle. Additionally, the vehicle includes a controller configured to interpret the information from the sensor to determine a length of at least a portion of a leg of a person. The controller is configured to instruct the motor to adjust the position of the deck based on the determined length.
1. A motor vehicle, comprising:
a running board assembly comprising a deck, a linkage assembly configured to guide movement of the deck, and a motor configured to move the linkage assembly to adjust a position of the deck;
a sensor configured to obtain information indicative of activity adjacent an exterior of the motor vehicle; and
a controller configured to interpret the information from the sensor to determine a length of at least a portion of a leg of a person, and wherein the controller is configured to instruct the motor to adjust the position of the deck based on the determined length.
2. The motor vehicle as recited in claim 1 , wherein:
the controller is configured to interpret the information from the sensor to determine a gait of the person, and
the controller is configured to adjust the position of the deck based on the determined length only when the controller determines that the gait of the person is normal.
3. The motor vehicle as recited in claim 2 , wherein:
the controller is configured to interpret the information from the sensor to determine that the person has an abnormal gait, and
if the controller identifies that the person has an abnormal gait, the controller is configured to instruct the motor to adjust the position of the deck based on one or more of a body length of the person, an arm length of the person, and grab handle height.
4. The motor vehicle as recited in claim 1 , wherein:
the controller is configured to interpret the information from the sensor to determine a speed of the person, and
the controller is configured to instruct the motor such that the position of the deck is adjusted before the person is in a position to enter the motor vehicle.
5. The motor vehicle as recited in claim 1 , wherein:
in response to instructions from the controller, the motor is configured to adjust a position of the deck between a stowed position and one of a plurality of predefined deployed positions, and
in each of the predefined deployed positions, the deck is at a different height from a ground surface relative to each of the other deployed positions.
6. The motor vehicle as recited in claim 5 , wherein the controller is configured to issue an instruction to the motor to move the deck to a particular one of the plurality of deployed positions based on the information from the determined length.
7. The motor vehicle as recited in claim 1 , wherein the controller is configured to instruct the motor to adjust a height position of the deck relative to a ground surface, a lateral position of the deck relative to a body of the motor vehicle, and an angular position of the deck based on the information from the sensor.
8. The motor vehicle as recited in claim 1 , wherein:
the position of the deck is adjusted based on one or more factors in addition to the determined length based on a mode selected by a user of the motor vehicle,
in a first mode, the additional factors include curb height and floor height, and
in a second mode, the additional factors include curb height, floor height, and seat height.
9. The motor vehicle as recited in claim 1 , wherein, in addition to the determined length, the controller is configured to instruct the motor to adjust the position of the deck based on one or more of a curb height, a floor height, and a seat height.
10. The motor vehicle as recited in claim 1 , wherein:
the controller is configured to use the information from the sensor to recognize the person as an authorized user, and
if the authorized user has a predefined deck position setting, the controller is configured to instruct the motor to set the position of the deck to the predefined deck position setting.
11. The motor vehicle as recited in claim 1 , wherein:
the controller is configured to interpret the information from the sensor as a plurality of people adjacent the motor vehicle,
the controller is configured to determine an ideal position of the deck for each of the plurality of people based at least on a leg length of each of the plurality of people, and
the controller is configured to rank the plurality of people and to instruct the motor to position the deck to the ideal position corresponding to the higher-ranked of the plurality of people.
12. The motor vehicle as recited in claim 1 , wherein the controller is configured to interpret the information from the sensor to determine the length of one or both of a femur or a tibia of the person.
13. The motor vehicle as recited in claim 1 , wherein:
the controller is configured to remember the position,
the controller is configured to instruct the motor to move the deck from the position to a stowed position to after the person enters the motor vehicle, and
in anticipation of the person exiting the motor vehicle, the controller is configured to instruct the motor to move the deck from the stowed position back to the position.
