Further, different pressure differences may be generated according to the difference of the duty ratios and phases of the first pulse signal and the second pulse signal, so that the vibration feedback device 1 generates different types of vibrations. For convenience of description, the first pulse signal is denoted by V1, the second pulse signal is denoted by V2, and the differential pressure acting on the vibration feedback device 1 is denoted by Δ V.
In one embodiment, as shown in fig. 3, the output periods of the first pulse signal V1 and the second pulse signal V2 are both T1, and the duty ratios of the first pulse signal V1 and the second pulse signal V2 are different, but the duty ratios of the first pulse signal V1 and the second pulse signal V2 are different, so that the pressure difference Δ V can be generated in the same output period T1. In the present embodiment, since the duty ratio of the second pulse signal V2 is greater than the duty ratio of the first pulse signal V1, and the second pulse signal V2 is input to the negative input terminal of the vibration feedback device 1, the Δ V after the first pulse signal V1 and the second pulse signal V2 are applied is indicated by a negative value.
In one case of this embodiment, the vibration period of the vibration feedback device 1, the output period of the first pulse signal V1, and the output period of the second pulse signal V2 may be both T1, so that the differential pressure acting on the vibration feedback device 1 may also be periodically changed with the period of T1, which is beneficial for controlling the vibration type of the vibration feedback device 1.
In another case of this embodiment, the vibration period of the vibration feedback device 1 may not be equal to the output period of the first pulse signal V1 and the output period of the second pulse signal V2. For example, one vibration cycle of the vibration feedback device 1 may correspond to the output cycles of the plurality of first pulse signals V1 and second pulse signals V2; and the duty ratio of at least one output period of the first pulse signal V1 is different from the duty ratio of the corresponding output period of the second pulse signal within a single vibration period.
For example, as shown in fig. 4, the output period of the first pulse signal V1 and the second pulse signal V2 is T2, the vibration period of the vibration feedback device 1 is T2, and a single vibration period T2 may correspond to 8 output periods T1. Wherein, the duty ratios of the first pulse signal V1 and the second pulse signal V2 in the second output period, the third output period and the fourth output period are different.
In this embodiment, as shown in fig. 4, the duty ratios of the output periods T1 of the first pulse signal V1 corresponding to the half vibration period T2 are increased and then decreased, and the duty ratios of the output periods T1 of the first pulse signal corresponding to the other half vibration period T2 are unchanged; similarly, as shown in fig. 5, the duty ratios of the plurality of output periods T1 of the second pulse signal V2 corresponding to the half vibration period T2 are not changed, and the duty ratios of the plurality of output periods T1 of the second pulse signal V2 corresponding to the other half vibration period T2 are not increased and then decreased.

In an embodiment, as shown in fig. 4, it is assumed that one vibration period T2 may correspond to 8 output periods T1, the duty ratio of the first pulse signal V1 in 4 output periods corresponding to the first half of the vibration period is increased and then decreased, the duty ratio of the second pulse signal V2 in 4 output periods corresponding to the second half of the vibration period is unchanged, and the duty ratio of the second pulse signal V2 in 8 output periods corresponding to the entire vibration period is unchanged. When the duty ratio of the second pulse signal V2 is less than or equal to the minimum duty ratio of the first pulse signal V1, the pressure difference acting on the vibration feedback device 1 may be represented by a positive pressure difference as shown in fig. 4, for example, the duty ratio of the second pulse signal V2 in fig. 4 may be 50%, and the minimum duty ratio of the first pulse signal V1 is 50%; when the duty ratio of the second pulse signal V2 is greater than the maximum duty ratio of the first pulse signal V1, the pressure difference acting on the vibration feedback device 1 may be represented as a negative pressure difference, and of course, the duty ratio of the second pulse signal V2 may be greater than the minimum duty ratio of the first pulse signal V1 and less than or equal to the maximum duty ratio of the first pulse signal V1, which is not limited by the present disclosure.
In another embodiment, as shown in fig. 5, it is assumed that one vibration period T2 may correspond to 8 output periods T1, the duty ratio of the second pulse signal V2 in 4 output periods corresponding to the first half of the vibration period is not changed, the duty ratio of the second pulse signal V2 in 4 output periods corresponding to the second half of the vibration period is increased and then decreased, and the duty ratio of the first pulse signal V1 in 8 output periods corresponding to the entire vibration period is not changed. For details, reference may be made to the embodiment shown in fig. 4 between the duty ratio of the first pulse signal V1 and the duty ratio of the second pulse signal V2, and details are not repeated here.
In a further embodiment, as shown in fig. 6, it is assumed that one vibration period T2 may correspond to 8 output periods T1, the duty ratios of the first pulse signal V1 and the second pulse signal V2 in 4 output periods corresponding to the first half vibration period increase and then decrease, and the duty ratios of the first pulse signal V1 and the second pulse signal V2 in 4 output periods corresponding to the second half vibration period do not change. In the second output period, the duty ratio of the first pulse signal V1 is different from the duty ratio of the second pulse signal V2, for example, in fig. 5, the duty ratio of the second pulse signal V2 is greater than the duty ratio of the first pulse signal V1 in the second output period. Of course, in other embodiments, the duty ratio of the first pulse signal V1 and the duty ratio of the second pulse signal V2 may be different in other output periods, or the duty ratio of the first pulse signal V1 may be larger than the duty ratio of the second pulse signal V2.
In yet another embodiment, as shown in fig. 7, it is assumed that one vibration period T2 may correspond to 8 output periods T1, the duty ratio of the first pulse signal V1 in 4 output periods corresponding to the first half vibration period increases and then decreases, the duty ratio of the first pulse signal V1 in 4 output periods corresponding to the second half vibration period does not change, the duty ratio of the second pulse signal V2 in 4 output periods corresponding to the first half vibration period does not change, and the duty ratio of the second pulse signal V2 in 4 output periods corresponding to the second half vibration period increases and then decreases. As shown in fig. 7, in the first half of the vibration period T2, the minimum duty cycle of the first pulse signal V1 is equal to the duty cycle of the second pulse signal V2, and in the second half of the vibration period T2, the duty cycle of the first pulse signal is equal to the minimum duty cycle of the second pulse signal V2, so that the pressure difference formed by the first pulse signal V1 and the second pulse signal V2 and acting on the vibration feedback device 1 may be a positive value and a negative value, and the pressure difference may form an analog signal having a substantially sinusoidal form as shown in fig. 8 after acting on the vibration feedback device 1 as a digital signal, and the vertical axis may be the amplitude or frequency of the vibration feedback device, and the horizontal axis is the time.
For example, as shown in fig. 7, during the first half of the vibration period T2, that is, during the first, second, third, and fourth output periods T1 of the first pulse signal V1 and the second pulse signal V2, the duty ratio of the first pulse signal V1 may be increased from 50% to 100% and then decreased from 100% to 50%, and the duty ratio of the second pulse signal V2 may be maintained at 50%; whereas in the second half of the vibration period T2, that is, in the fifth, sixth, seventh and eighth output periods T1 of the first pulse signal V1 and the second pulse signal V2, the duty ratio of the first pulse signal V1 may be maintained at 50%, and the duty ratio of the second pulse signal V2 may be increased from 50% to 100% and then decreased from 100% to 50%. The process that the duty ratio of the first pulse signal V1 is increased first and then decreased may be a process of linear change, or may also be a process of step-like change; in a similar manner, the balance of the vehicle,
the process of increasing the duty ratio of the second pulse signal V2 first and then decreasing the duty ratio may be a linear change process, or may be a stepwise change process, and the disclosure is not limited thereto.

Further, one vibration period T2 may also correspond to another number of output periods T1, for example, one vibration period corresponds to six or seven output periods, and the disclosure is not limited thereto.
In the above embodiments, as shown in fig. 3 to 7, the corresponding time instants of the rising edges of the first pulse signal V1 and the second pulse signal V2 are the same, so as to simplify the processing procedure. In another embodiment, the rising edges of the first pulse signal V1 and the second pulse signal V2 may have different timings, so that a phase difference is generated between the first pulse signal V1 and the second pulse signal V2 to adjust the timing of generating the voltage difference.
In contrast to the case where the duty ratios of the first pulse signal V1 and the second pulse signal V2 are different in the respective embodiments described above, in the embodiment to be described immediately below, as shown in fig. 9, the duty ratios of the first pulse signal V1 and the second pulse signal V2 are the same, and there is a phase difference between the first pulse signal V1 and the second pulse signal V2. For example, as shown in fig. 9, the duty ratios of the first pulse signal V1 and the second pulse signal V2 are both 50%, and the first pulse signal V1 and the second pulse signal V2 have a phase difference of 180 °.
