For achieving the above object, provide a kind of E-Gas proving installation according to the utility model, comprising: worktable, and be arranged on drive motor and controller on the worktable, drive motor drives by acceleration cable and presses E-Gas to be detected; Controller is used for drive motor is carried out speed governing, and then adjusts the speed of pressing for the treatment of the detected electrons throttle, and the accelerator pedal position signal of the pedal displacement sensor of receiving and analyzing E-Gas to be detected output.
In the technique scheme, drive motor and E-Gas to be detected are more than two, and two above drive motor and E-Gas to be detected one by one corresponding the driving are pressed.
In the technique scheme, controller comprises: pedal displacement sensor supply module, motor speed control module and pedal position signal collection analysis module;
Pedal displacement sensor supply module is connected with the pedal displacement sensor of E-Gas to be detected, is used to the pedal displacement sensor power supply of E-Gas to be detected;
The motor speed control module is connected with drive motor, be used for to change the speed of drive motor, treat with adjustment the detected electrons throttle pedal press speed;
Pedal position signal collection analysis module is connected with the pedal displacement sensor of E-Gas to be detected, is used for the accelerator pedal position signal of receiving and analyzing pedal displacement sensor output.
In the technique scheme, the motor speed control module is connected with drive motor by the control wire harness.
In the technique scheme, pedal position signal collection analysis module is connected with the pedal displacement sensor of E-Gas to be detected by the signal wire harness.
Compared with prior art, the utlity model has following beneficial effect: this E-Gas proving installation is simple and reasonable, by the press speed of controller control drive motor to E-Gas, has improved measuring accuracy; And can carry out separately fail-test, and increased the independence of test, simplified testing procedure and operation.

Embodiment
Below in conjunction with accompanying drawing, an embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subjected to the restriction of embodiment.It will be appreciated that, mentioned in the following embodiment of the present utility model " on ", D score, " left side ", " right side ", " front " and " reverse side " be all take the direction shown in each figure as benchmark, these words that are used for limiting direction only are for convenience of explanation, do not represent the restriction to the concrete technical scheme of the utility model.
As shown in Figure 1, E-Gas proving installation of the present utility model is to control drive motor by the controller of proving installation E-Gas is carried out pressing operation, replace existing by the operation of tester's Manual press, to an E-Gas or simultaneously a plurality of E-Gas are tested, thereby realize the Data Comparison analytic function to a plurality of E-Gas, its concrete structure comprises: worktable 1, drive motor 2 and controller 3, drive motor 2 and controller 3 are installed on the worktable 1, controller 3 is by driving frequency and the recently speed governing of duty of change drive motor 2, and then adjustment is to the speed of pressing of E-Gas.
