The structure of the footrest assembly according to the embodiment of the present disclosure is described above, and the control scheme of the present disclosure based on the footrest assembly is described below with reference to fig. 7.

First, as the concept of the control scheme of the present disclosure, the present disclosure provides a control method of a footrest assembly, which includes detecting a fatigue condition of a driver and/or detecting a driving condition of a vehicle, and controlling the operation of the reminding device 5 to remind the driver to switch driving modes when detecting that the driver is in fatigue and/or the vehicle is in emergency braking.

Specifically, in order to realize the control method, the control system of the footrest assembly provided by the present disclosure includes the controller 6 and the footrest assembly disclosed above, and the controller 6 is electrically connected with the reminding device 5 on the pedal body 1 to control the reminding device 5 to work, and the controller 6 may be an ECU of the vehicle.

As shown in fig. 7, when the controller 6 receives the fatigue signal "1" (specifically, the driver's spirit can be monitored in real time by the camera, and the camera sends out the signal when monitoring that the driver is in a fatigue state), the controller sends out control signals to the first signal processor 7 through pins Sign2, Sign3, Sign4, and Sign5, and the signals are converted into driving signals through the processing of the first signal processor 7, so as to drive the vibration motor to rotate, thereby realizing vibration reminding. Or in the automatic driving mode, when the vehicle sends an emergency braking signal, the controller can be caused to control the rotation of the vibrating motor.

Further, the control method of the present disclosure further includes detecting a sitting position of the driver; the support adjusting mechanism 3 is controlled to adjust the rotation angle of the pedal body 1 relative to the base 2 according to the sitting position of the driver, so that the pedal body 1 is suitable for being supported on the foot surface of the driver.

To implement this control method, in the embodiment of the present disclosure, the controller 6 is electrically connected to the support adjusting mechanism 3 to control the support adjusting mechanism 3 to adjust the rotation angle of the pedal body 1 relative to the base 2.

As shown in fig. 7, when the controller 6 receives the signal "0" for switching the driving mode, and when the driver switches the driving mode, for example, switches from the manual driving mode to the automatic driving mode, or switches from the automatic driving mode to the manual driving mode, it will output a control signal to the second signal processor 8 through a Sign6 pin, and convert the signal into a driving signal through the signal processor 8, so as to drive the linear motor to operate, so as to adjust the rotation angle of the pedal body 1, thereby satisfying the comfort of the foot of the driver in the current mode. For example, when the manual driving mode is switched to the automatic driving mode, the driver does not need to operate feet during automatic driving, and the driver can lean the sitting posture properly to lean against the backrest, so that the included angle between the pedal body 1 and the base 2 can be increased to adapt to the foot surface of the driver; when the automatic driving mode is switched to the manual driving mode, the driver needs to operate the automatic driving mode, the sitting posture is straight, and the included angle between the pedal body 1 and the base 2 needs to be reduced at the moment, even the included angle is approximately parallel to the floor metal plate, so that the aim of fitting the foot surface of the driver is fulfilled.

It should be noted that the rotation angle of the pedal body 1 required by the driver in different driving modes can be preset, so that the pedal body 1 can automatically stop after rotating to the preset angle; or in order to adapt to the foot surfaces of drivers with different body types, a stop key can be arranged on the control panel, and the driver can press the stop key to stop the rotation of the pedal body 1, so that the disclosure is not limited.

The preferred embodiments of the present disclosure are described in detail with reference to the accompanying drawings, however, the present disclosure is not limited to the specific details of the above embodiments, and various simple modifications may be made to the technical solution of the present disclosure within the technical idea of the present disclosure, and these simple modifications all belong to the protection scope of the present disclosure.

It should be noted that, in the foregoing embodiments, various features described in the above embodiments may be combined in any suitable manner, and in order to avoid unnecessary repetition, various combinations that are possible in the present disclosure are not described again.

In addition, any combination of various embodiments of the present disclosure may be made, and the same should be considered as the disclosure of the present disclosure, as long as it does not depart from the spirit of the present disclosure.
