[0066] This invention provides a method for testing the low-temperature vibration performance of a certain number of oscillator device samples to obtain the curve of the vibration acceleration of the oscillator device samples as a function of temperature. Then, a vibration driving force compensation curve is designed. Based on this vibration driving force compensation curve, the vibration driving force of the vibration feedback device is compensated at different temperatures, so that the vibration feedback tactile sensation of the vibration feedback device at different temperatures tends to be consistent, thereby improving the user's perception experience.

[0067] like Figure 1 The diagram shown is a flowchart of one step of the vibration feedback tactile compensation method provided in an embodiment of the present invention. (Refer to...) Figure 1 This invention provides a vibration feedback tactile compensation method, which specifically includes the following steps:

[0068] S101. Obtain the first vibration acceleration of multiple oscillator device samples under a preset driving force and a first temperature, and generate the vibration acceleration change curve of the oscillator device samples based on the first vibration acceleration and the first temperature.

[0069] like Figure 2The diagram shown is a flowchart of step S101 provided in an embodiment of the present invention. (Refer to...)

[0072] Specifically, this invention tests the vibration acceleration of 50 oscillator device samples under a preset driving force and conditions ranging from -40℃ to 30℃. The average vibration acceleration of the 50 oscillator device samples under the same temperature condition is calculated to obtain the average vibration acceleration under the corresponding temperature condition. The test data under different temperature conditions are processed in the above manner to obtain the first mapping relationship between the average vibration acceleration and temperature. Then, curve fitting is performed using software to obtain the vibration acceleration variation curve, as shown below. Figure 3 The figure shown is a schematic diagram of a vibration acceleration variation curve provided in an embodiment of the present invention.

[0073] S102. Determine the vibration driving force compensation value at different temperatures based on the vibration acceleration variation curve, and obtain the vibration driving force compensation curve.

[0076] S1022. Determine the vibration driving force compensation value based on the vibration acceleration compensation value, and then determine the second mapping relationship between the vibration driving force compensation value and the second temperature;

[0077] S1023. Obtain the vibration driving force compensation curve by curve fitting according to the second mapping relationship.

[0078] Specifically, according to Figure 3It is known that the vibration acceleration of the oscillator device sample decreases under low temperature conditions. Correspondingly, this embodiment of the invention determines the vibration acceleration compensation value based on the value of the decrease in vibration acceleration. When the model of the oscillator device sample (or vibration feedback device) is known, the corresponding vibration driving force compensation value can be determined based on the vibration acceleration compensation value, thereby obtaining a second mapping relationship between the vibration driving force compensation value and temperature. Then, the vibration driving force compensation curve is obtained by curve fitting. Figure 5 The figure shows a schematic diagram of a vibration driving force compensation curve provided in an embodiment of the present invention. The blue part in the figure represents the second mapping relationship between the vibration driving force compensation value and the temperature, and the red part is the fitted vibration driving force compensation curve. It can be seen that the lower the temperature, the greater the vibration driving force compensation value, thereby ensuring that the vibration feedback tactile sensation tends to be consistent at different temperatures.

[0079] S103. Determine the ambient temperature value of the target vibration feedback device, and determine the target driving force compensation value based on the ambient temperature value and the vibration driving force compensation curve.

[0080] like Figure 6 The diagram shown is a flowchart of step S103 provided in an embodiment of the present invention. (Refer to...)

[0082] S1032. Based on the ambient temperature value, the vibration driving force compensation value at the corresponding temperature is obtained by matching the vibration driving force compensation curve and used as the target driving force compensation value.

[0083] Specifically, a temperature sensor is installed on the target vibration feedback device to obtain the ambient temperature value. Then, based on the ambient temperature value, the vibration driving force compensation value at the corresponding temperature is matched in the vibration driving force curve for subsequent compensation and adjustment of the vibration driving force of the target vibration feedback device.

[0084] In some alternative embodiments, the target vibration feedback device may be a smart surface product on a vehicle.

[0085] S104. Adjust the vibration driving force of the target vibration feedback device according to the target driving force compensation value.

[0086] like Figure 7 The diagram shown is a flowchart of step S104 provided in an embodiment of the present invention. (Refer to...)

[0089] S1043, The vibration control module that sends the target vibration driving force to the target vibration feedback device.

[0090] Specifically, after obtaining the first vibration driving force preset by the target vibration feedback device, the target driving force compensation value is summed with the first vibration driving force to obtain the target vibration driving force, which is then sent to the vibration control module of the target vibration feedback device to generate a corresponding driving signal to drive the built-in oscillator device to vibrate.
