2. The apparatus according to claim 1, wherein the pressure detecting member includes a first pressure sensor and a second pressure sensor, wherein the first pressure sensor and the second pressure sensor are each configured to detect the actual force value.
3. The apparatus of claim 2, wherein the position detector is further configured to:
when the first pressure sensor detects the actual stress value, detecting that the actual stress position is a first position;
and when the second pressure sensor detects the actual stress value, detecting that the actual stress position is a second position.
4. The apparatus of claim 2, wherein the controller is further configured to determine the current intent as an acceleration intent based on the first position and determine the current intent as a braking intent based on the second position.
5. The apparatus of any of claims 1-4, further comprising:
the recognizer is used for recognizing the identity information of the user;
the controller is further used for controlling the equipment to be switched on or switched off according to the identity information.
6. A control method of an operating device of an accelerator and a brake of an automobile according to any one of claims 1 to 5, comprising the steps of:
detecting an actual stress value of the equipment body;
detecting an actual stressed position of the equipment body; and
and identifying the current intention of a driver according to the actual stress position, controlling the power system of the automobile to output torque or moment according to an acceleration instruction matched with the actual stress value when the current intention is an acceleration intention, and controlling the braking system of the automobile to brake according to a braking instruction matched with the actual stress value when the current intention is a braking intention.
7. The method of claim 6, wherein the pressure detecting member comprises a first pressure sensor and a second pressure sensor, and the detecting the actual force-receiving position of the apparatus body comprises:
when the first pressure sensor detects the actual stress value, detecting that the actual stress position is a first position;
and when the second pressure sensor detects the actual stress value, detecting that the actual stress position is a second position.
8. The method of claim 7, wherein identifying the driver's current intent as a function of the actual force-receiving location comprises:
determining the current intent as an acceleration intent based on the first position and determining the current intent as a braking intent based on the second position.
9. The method according to any one of claims 6 to 8, characterized in that before detecting the actual force value of the apparatus body, it further comprises:
identifying identity information of a user;
and controlling the equipment to be switched on or switched off according to the identity information.
10. A computer-readable storage medium on which a computer program is stored, characterized in that the program is executed by a processor for implementing the control method of the operating device of the accelerator and brake of the automobile according to any one of claims 6 to 9.
