Problems solved by technology

But at present, the matching verification of starting performance is mainly based on subjective evaluation, and the shortcomings of subjective evaluation are very obvious. Different test drivers have different driving proficiency, and the evaluation results are also different. Personal preferences will also affect the evaluation results. The most important The most important thing is that there is no quantitative data provided to the matching engineers for analysis, only the matching parameters are adjusted repeatedly based on experience, which seriously reduces the matching efficiency

Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are only used to explain the present invention, and do not constitute a limitation to the protection scope of the present invention.

[0020] Such as figure 1 The vehicle starting performance objective evaluation system shown includes a clutch pedal control device 1, a traction test device 2, a clutch control system test device 3 and a data acquisition device.

[0021] see figure 2 The clutch pedal control device 1 is used to loosen and lift the clutch pedal at a certain speed. Controller for cylinder movement. After the driver's seat is disassembled, the bottom beam 101 is fixed on the driving position of the vehicle floor through the connecting plate 110 along the front and rear direction of the vehicle body. The seat plate 102 is installed on the bottom beam 101 and can be adjusted in position along the front and rear d...

Abstract

The invention discloses an objective evaluation system of automobile starting performance and a test method thereof. The system comprises a clutch pedal control device, a traction test device, a clutch control system test device and a data acquisition device. The data acquisition device collects the signals of each sensor, and drives the servo electric cylinder through the controller to realize the release and depression control of the clutch pedal. The invention can provide objective data support for the verification of the starting performance of the whole vehicle.

Description

technical field [0001] The invention relates to the field of vehicle performance matching, in particular to an objective evaluation system and a test method for vehicle starting performance. Background technique [0002] The starting performance is an important performance of the whole vehicle. Good starting performance can improve the customer's driving experience of the car and increase the joy of using the vehicle. complain. Therefore, the matching of starting performance is an indispensable part in the whole vehicle development process. But at present, the matching verification of starting performance is mainly based on subjective evaluation, and the shortcomings of subjective evaluation are very obvious. Different test drivers have different driving proficiency, and the evaluation results are also different. Personal preferences will also affect the evaluation results. The most important What is worse is that there is no quantified data provided to the matching engine...
