[0055] see figure 1 , the present invention provides the first embodiment of the accelerator control method for ride comfort test, this embodiment specifically includes:

[0056] S101: According to the information of the driving road, the model of the test vehicle and the test vehicle speed value, it is judged whether there is corresponding accelerator setting information stored. If yes, execute S102.

[0057] In fact, before the ride comfort test, it is first necessary to determine the driving road used in this test, the test vehicle and the speed value of the vehicle during the test.

[0058] In this embodiment, a plurality of throttle setting information may be stored in the storage unit, and each throttle setting curve corresponds to information of a specific driving road, the model of the test vehicle and the value of the test vehicle speed. Wherein, the information of the driving road refers to the information used to represent the driving road, which may be the name o...

[0098] see image 3 , the present invention provides the second embodiment of the accelerator control method for ride comfort test, this embodiment specifically includes:

[0099] S301: The control module judges whether the storage unit stores corresponding accelerator setting information according to the information of the driving road, the model of the test vehicle, and the test vehicle speed. If yes, execute S307. If not, execute S302.

[0100] The control module in this embodiment may be control chips such as ARM, FPGA, engine electronic control unit (Electronic control unit, ie ECU), DSP and so on.

[0101] Before this step, the driving road, the model of the test vehicle and the value of the test vehicle speed can be determined first. Among them, the driving road refers to the road that can be used for the ride comfort test, and the road is allowed to have a small slope. It is required that when the car travels back and forth at a constant speed, the difference in the...

Abstract

The invention provides a throttle control method and system used for a ride comfort test. The method includes: judging whether corresponding throttle setting information is stored; and if yes, controlling the throttle opening degree of a test vehicle during driving on a driving road in the ride comfort test according to the stored throttle setting information. A storing process of the throttle setting information specifically includes: acquiring a plurality of sample data sets; judging whether each of the sample data sets satisfies a stable condition, and if no, deleting the sample data set; judging whether each of the sample data sets that are not deleted is valid, and if yes, generating throttle setting information according to the throttle opening degree in each of the sample data sets that are not deleted; and storing the generated throttle setting information as corresponding throttle setting information. The throttle control method used for the ride comfort test can automatically control the throttle opening degree according to the generated throttle setting information, and reduce difference of influence on a test result, thereby improving repeatability of the ride comfort test.

Description

technical field [0001] The invention relates to the field of mechanical control, in particular to an accelerator control method and system for ride comfort test. Background technique [0002] When the vibration and impact generated by the vehicle during driving are relatively large, it may cause discomfort to the passengers or damage the goods in the vehicle. At present, the vibration and shock generated by the car during driving are mainly tested through the ride comfort test. [0003] During the ride comfort test, there will be some special requirements for the driving of the vehicle, such as keeping the speed of the vehicle and the throttle opening as consistent as possible, etc. Otherwise, the test results of the ride comfort test will be affected. At present, the above-mentioned special requirements are mainly realized through the driver's control of the vehicle. [0004] However, this way of completely controlling the vehicle by the driver is highly subjective and ha...
