Description

TECHNICAL FIELD

[0001] The present application relates to the field of automobile detection, and in particular to an intelligent comprehensive performance detection system for automobiles. BACKGROUND

[0002] With the continuous improvement of the intelligence and networking of automobiles, the in-vehicle human-machine interaction interface is filled with a large number of physical keys, capacitive touch keys and virtual center console screen soft keys. Users' requirements for interaction fluency are also increasing. A functional key needs to go through multiple links such as signal acquisition, bus transmission, ECU processing and actuator driving from being triggered to finally executing the corresponding function, and the detection of the functional key is mostly limited to the binary judgment of "whether the function is effective", and lacks performance evaluation of "whether the response is timely". When users complain about "slow response of the key" and "stuttering of the vehicle machine", maintenance personnel lack effective tools to quantify the delay and can only rely on subjective feelings, resulting in low diagnostic efficiency and difficulty in problem reproduction.

[0003] Currently, the "time" key performance indicator is not included in the test results of the vehicle functional key, and the user-perceptible "stuttering", "delay" or "slow response" and other phenomena cannot be captured. In a static and low-load environment, the function may be "effective". However, when the vehicle is started, high-power electrical appliances are running, the road is bumpy or the vehicle machine system is under high load, the system resources are strained, the response time may increase dramatically, and even intermittent failure may occur, and the traditional binary test cannot reproduce and capture such dynamic performance degradation.

[0004] The present application builds a benchmark functional response performance data set for the vehicle functional key in advance by setting up a vehicle multi-working-condition functional key test, establishes quantifiable performance benchmark data, captures the functional key feedback signals under static, smooth and bumpy working conditions of the vehicle using multiple sensors, analyzes the comprehensive detection delay data of the vehicle under multi-working conditions, performs multi-working-condition comprehensive evaluation on the vehicle functional key, captures the functional key performance error, and performs vehicle after-sales data feedback.

If the vibration frequency and amplitude are consistent with the inherent frequency of the vehicle driving at a constant speed, and there is no obvious high-frequency impact, it is judged that the vehicle is in a stable dynamic working condition. If the vibration frequency and amplitude are greater than the set threshold value, and there are multiple high-frequency amplitudes, it is judged that the vehicle is in a jolting dynamic working condition.
