[0022] The technical solution of the utility model is further described below through the accompanying drawings and embodiments.

[0023] Unless otherwise defined, technical or scientific terms used in the present invention should have the common meanings understood by persons having ordinary skills in the field to which the present invention belongs.

[0024] Embodiment 1

[0025] like Figure 1-Figure 8As shown, the utility model is an intelligent automobile inspection auxiliary system, including a main control machine 1, an actuator 2 and an OBD diagnostic instrument 3. The main control machine 1 includes a tablet computer 11 and a signal processing device 12, and the signal processing device 12 is connected to the tablet computer 11. The main control machine 1 is connected to the actuator 2, and the actuator 2 includes a fixing device 21 and an actuator push rod 22. The OBD diagnostic instrument is connected to the main control machine 1.

[0026] The actuator push rod 22 includes a gear 221 and a screw rod 222, wherein the gear 221 is located above the screw rod 222. The gear 221 can be axially retracted, and the gear 221 is separated from the screw rod 222, and the screw rod 222 is recovered under the action of a return spring.

[0027] The fixing device 21 includes a connecting ring 211 and a fixing bolt 212. The connecting ring 211 is U-shaped. One side of the connecting ring 211 is connected to the actuator push rod 22. One side of the actuator push rod 22 is connected to the pedal. The other side of the connecting ring 211 is connected to the seat through the fixing bolt 212.

[0028] The main control machine 1 is composed of a tablet computer 11 and a signal processing device 12. The tablet computer 11 is installed with detection control software, which is responsible for logging detection items and information and implementing logical control of the detection process; the signal processing device 12 is responsible for receiving computer instructions and outputting control signals and executing logical instructions. The main control machine 1 is connected to the actuator 2 and the OBD diagnostic instrument through signal and control lines.

[0029] The actuator 2 is connected to the main control machine 1 to execute and realize the control of the pedal by the main control machine 1, such as pressing the pedal quickly, pressing the pedal slowly, keeping the pedal steady, releasing the pedal slowly, releasing the pedal quickly, etc.

[0030] The gear 221 is controlled by a stepper motor to achieve controllable expansion and contraction of the shaft in the sleeve and position retention. The gear 221 can be axially expanded and contracted. When the gear 221 contracts, that is, retreats toward the motor direction, it will be separated from the screw 222. After the gear 221 is separated from the screw 222, the screw 222 will be recovered under the action of the reset spring, so that the actuator push rod 22 of the actuator 2 is shortened to the minimum size, thereby interrupting the contact relationship with the pedal and resetting the pedal.

[0031] The OBD diagnostic instrument is installed on the vehicle to be inspected and connected to the main control computer 1. It is responsible for transmitting the relevant status and real-time information of the vehicle to the control software of the main control computer 1, so that the control software of the main control computer 1 can perceive the real-time status of the vehicle. The control software of the main control computer 1 controls the actuator 2 according to the detection logic, thereby realizing the control of the vehicle.

[0032] Select "Dual Idle" to enter the detection software. The software will first prompt "The coolant or lubricating oil temperature is not less than 80°C". At this time, the coolant or lubricating oil temperature of the vehicle is read by the OBD diagnostic instrument 3 and displayed in real time on the display screen. After the temperature reaches 80°C, the software prompts "Increase to 70% of the rated speed". At this time, the detection software of the tablet computer 11 will command the signal processing device 12 to output a control signal to the actuator 2. The actuator 2 will slowly push the accelerator pedal to gradually increase the throttle opening. At this time, the engine speed gradually increases. The OBD diagnostic instrument 3 will transmit the read real-time engine speed to the tablet computer 11, and the detection software will display this information on the test interface. After the engine speed reaches a predetermined value (for example, the rated speed is 6000r / min, and 70% of the rated speed is 4200r / min), the detection software of the tablet computer 11 will command the signal processing device to output a control signal to the actuator to stop moving, and the engine speed will remain in this state for 30 seconds. The control process is as follows Figure 6 shown.

[0033] After the rated speed is increased to 70% and maintained for 30 seconds, the detection software of the tablet computer 11 will command the signal processing device 12 to output a control signal to the actuator 2 to gradually reduce the accelerator pedal opening. After the engine speed reaches the high idle speed (2500r / min for light vehicles), the engine speed is maintained at this position. The software prompts to insert the sampling probe of the dual idle method emission tester into the exhaust pipe and fix it on the exhaust pipe. After maintaining for 15 seconds, the average value of the vehicle emissions for 30 seconds is read as the high idle pollutant measurement result, and the value of the excess air coefficient is calculated at the same time. The control process is as follows Figure 7 shown.

[0034] After the high idle measurement is completed, the detection software of the tablet computer 11 will command the signal processing device 12 to output a control signal to the actuator 2 to gradually reduce the accelerator pedal opening, and finally the actuator 2 will be disengaged from the accelerator pedal, and the engine speed will return to the idle state. After maintaining for 15 seconds, the average value of the vehicle emissions for 30 seconds is read as the high idle pollutant measurement result. The control process is as follows Figure 8 shown.

[0035] Therefore, the utility model adopts the above-mentioned intelligent automobile inspection auxiliary system to make the inspection process more reliable and stable, and the inspection results more scientific and objective, thereby reducing the adverse effects of human control errors on the inspection.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that they can still modify or replace the technical solution of the utility model with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the utility model.
