Problems solved by technology

[0008] 1. Due to factors such as driving skills, psychological expectations, and fatigue levels of different driving testers, the scoring results vary greatly
[0009] 2. In order to obtain more objective and true evaluation results, a large number of driving evaluation samples and repetitive work are often required, and the workload is relatively large
[0010] 3. It is difficult to find some subtle drivability differences and problems

Abstract

The invention discloses an evaluation method for accelerator transient condition driveability. The method includes the steps of collecting vehicle signals in real time when a vehicle runs; judging accelerator transient conditions on the basis of the collected vehicle signals; calculating multiple evaluation indexes under each accelerator transient condition to obtain a calculated value of each evaluation index under each accelerator transient condition; conducting calculation to obtain a grading result of each evaluation index under each accelerator transient condition through a preset formula; conducting calculation to obtain a comprehensive evaluation result of each accelerator transient condition through another preset formula; and outputting the time period of each accelerator transient condition, the calculated value of each evaluation index, the grading result of each evaluation index and the comprehensive evaluation results.

Description

technical field [0001] The invention relates to the technical field of automobile electronic control, in particular to a drivability evaluation method under transient throttle conditions and a drivability evaluation system under transient throttle conditions. Background technique [0002] Vehicle drivability evaluation is an important link in the vehicle development process. At present, domestic automobile companies usually use subjective evaluation methods, that is, to evaluate the driver's subjective feeling of vehicle driving comfort. Subjective evaluation includes qualitative evaluation and quantitative evaluation. Qualitative evaluation generally refers to the comparison of the relative advantages and disadvantages of drivability among vehicles. Quantitative evaluation generally adopts the subjective scoring method, that is, the subjective driving experience of the vehicle is graded with numerical scores. [0003] Even if the quantitative subjective evaluation method is...
