Example 1
Fig. 1 is a schematic diagram of a control system of a vehicle seat according to an embodiment of the present invention, which includes the following components, as shown in fig. 1: motor 12, switch assembly 14, drive circuit 16, controller 18.
A first level signal is input to a first end of the switching element 14, a second end of the switching element 14 is connected to a first end of the driving circuit 16, a third end of the switching element 14 is connected to a second end of the driving circuit 16, a third end of the driving circuit 16 is connected to a control end of the controller 18, a fourth end of the driving circuit 16 is connected to a first end of the motor 12, and a fifth end of the driving circuit 16 is connected to a second end of the motor 12.
The motor 12 is used to control the folding or unfolding of the vehicle seat.
The vehicle seat may be a rear seat of a vehicle, wherein the vehicle may be an automatic driving vehicle or a manual driving vehicle, and the type of the vehicle is not limited herein.
The motor 12 can be used to drive the vehicle seat to change its state through different rotating directions, for example, the motor 12 rotates leftwards to drive the vehicle seat to fold, or the motor 12 rotates rightwards to drive the vehicle seat to unfold, where the corresponding relationship between the specific rotating direction of the motor 12 and the state transition manner of the vehicle seat is not limited. Alternatively, the motor 12 may be a synchronous motor 12 or an asynchronous motor 12, and the type of the motor 12 is not limited herein.
The switching component 14 is used to determine whether to conduct the first terminal of the switching component 14 with the second terminal of the switching component 14 and whether to conduct the first terminal of the switching component 14 with the third terminal of the switching component 14.
The first level signal may be a high level signal, for example, a first terminal of the switch assembly 14 is connected to a positive pole of the dc power supply; the first level signal may also be a low level signal, for example, the first terminal of the switch assembly 14 is grounded, or the first terminal of the switch assembly 14 is connected to the negative pole of the dc power source. In the embodiment of the present invention, the first terminal of the switch module 14 is connected to the negative electrode of the dc power supply.
In an alternative embodiment, after detecting that the trunk of the vehicle is opened, the user may select whether the vehicle seat needs to be folded or unfolded on a virtual key of the vehicle body according to the requirement, or control whether the vehicle seat needs to be folded or unfolded through voice, wherein the user may be a passenger on the vehicle. Optionally, if the vehicle seat needs to be folded, the first end of the switch assembly 14 may output a first level signal, so that the first end of the switch assembly 14 is conducted with the second end of the switch assembly 14, and if the vehicle seat needs to be unfolded, the first end of the switch assembly 14 may output the first level signal, so that the first end of the switch assembly 14 is conducted with the third end of the switch assembly 14, so as to drive the vehicle seat to change in state.
The controller 18 is configured to determine whether to output a second level signal through a control terminal of the controller 18 based on a current state of a trunk of the vehicle, wherein the first level signal is different from the second level signal.
The current state of the trunk of the vehicle may be the trunk being opened or the trunk being closed.
In order to control the rotation direction of the motor and further the vehicle seat by the driving circuit, the second level signal may be different from the first level signal, for example, the first level signal is at a high level, and the second level signal is at a low level; the first level signal is at a low level and the second level signal is at a high level.
In an alternative embodiment, when the vehicle body sensor detects that the current state of the trunk of the vehicle is trunk open, the control terminal of the controller 18 may output a second level signal, and the first terminal of the switch assembly 14 inputs the first level signal, so that the first terminal of the switch assembly 14 is conducted with the second terminal of the switch assembly 14 or the third terminal of the switch assembly 14, and further, the state of the vehicle seat may be controlled to be changed according to whether the first level signal output from the second terminal or the third terminal of the switch assembly 14 and the second level signal output from the control terminal of the controller 18 are detected.
The driving circuit 16 is configured to drive an operating state of the motor 12 based on whether the first level signal and the second level signal are received, wherein the operating state includes the following: stop working, rotate according to the first direction, rotate according to the second direction.
The drive circuit 16 described above may include a plurality of relays.
Optionally, after the driving circuit 16 starts to work, the motor 12 rotates in the first direction, and the first end of the motor 12 is conducted with the fourth end of the driving circuit 16, so that the vehicle seat is folded. When the driving circuit 16 starts to operate, the motor 12 rotates in the second direction, and the second end of the motor 12 is conducted with the fifth end of the driving circuit 16, so that the vehicle seat is unfolded.
In an alternative embodiment, after the driving circuit 16 receives the second level signal output from the control terminal of the controller 18 and the first level signal output from the second terminal of the switch assembly 14 or the third terminal of the switch assembly 14, the operating state of the motor 12 may be driven according to the user's requirement, so that the vehicle seat is folded, unfolded or does not change state. Alternatively, the state of the vehicle seat may be controlled by controlling the rotational direction of the motor 12. For example, it may be assumed that the motor 12 rotates in a first direction, so that the first terminal of the switch assembly 14 and the second terminal of the switch assembly 14 are turned on, and a first level signal is output from the second terminal of the switch assembly 14, so that the vehicle seat is folded. Assuming that the motor 12 rotates in the second direction, so that the first terminal of the switching assembly 14 and the third terminal of the switching assembly 14 are conducted, the first level signal is outputted from the third terminal of the switching assembly 14 to deploy the vehicle seat. Alternatively, if the second level signal output from the control terminal of the controller 18 and the first level signals output from the second terminal and the third terminal of the switching assembly 14 are not detected, the motor 12 may stop operating.

It is easy to note that the driving circuit 16 may be utilized to drive the operating state of the motor 12 based on the first level signal output by the switch assembly 14 and the second level signal output by the control terminal of the controller 18, and control the vehicle seat based on the operating state of the motor 12, so that when the vehicle seat is directly controlled by using the switch and the relay, an unexpected seat control behavior is not generated while cost is reduced, and thus a complex control strategy may be implemented, thereby solving the technical problem of low efficiency in controlling the vehicle seat in the related art.
Optionally, the driving circuit 16 is further configured to stop the driving motor 12 in response to not receiving the first level signal or the second level signal; in response to receiving the first level signal and the second level signal output from the second end of the switch assembly 14, the drive motor 12 is rotated in a first direction, so that the vehicle seat is folded; in response to receiving the first level signal and the second level signal output from the third terminal of the switching assembly 14, the driving motor 12 rotates in the second direction, so that the vehicle seat is unfolded; in response to receiving the first level signal and the second level signal outputted from the second terminal and the third terminal of the switching assembly 14, the driving motor 12 stops operating.

In an alternative embodiment, the driving circuit 16 may drive the operation state of the motor 12 based on whether the first level signal output from the second terminal or the third terminal of the switching assembly 14 and the second level signal output from the control terminal of the controller 18 are received. Optionally, when the trunk of the vehicle is in an open state, the control terminal of the controller 18 outputs a second level signal, and the first terminal of the switch assembly 14 inputs a first level signal, and the switch assembly 14 is closed, so that the first terminal of the switch assembly 14 is connected to the second terminal of the switch assembly 14 and is conducted with one of the relays of the driving circuit 16, and the second terminal of the switch assembly 14 outputs the first level signal, so that the driving circuit 16 can be used to drive the motor 12 to rotate according to the first direction, thereby folding the vehicle seat. Optionally, when the trunk of the vehicle is in an open state, the control terminal of the controller 18 outputs a second level signal, and at the same time, the switching component 14 is closed, so that the first terminal of the switching component 14 is connected to the third terminal of the switching component 14 and is conducted with another relay of the driving circuit 16, and the first level signal output from the third terminal of the switching component 14 can drive the motor 12 to rotate according to the second direction by using the driving circuit 16, so as to deploy the vehicle seat.
