Adaptive parameter adjustment method in automotive advanced driver assistance system

Abstract

The invention discloses a self-adaption parameter adjustment method for an automobile advanced driver assistance system. The self-adaption parameter adjustment method includes the following steps: (1)an ADAS sets an alarm parameter fluctuant range and an initial car following parameter value when shipped; (2) in an initial use process of a vehicle, the ADAS automatically detects a distance between the vehicle itself and a front vehicle in real time, calculates an average car following time during one period, and amends the initial car following parameter value to obtain a self-adaption parameter value suitable for a user himself based on the average car following time; (3) in a post use process of the vehicle, the ADAS automatically detects the distance between the vehicle itself and the front vehicle in real time based on the current self-adaption car following parameter value, calculates alarm times, and subsequently amends the current self-adaption car following parameter value by determining whether the alarm times per unit time reaches the upper limit or not. According to the invention, the self-adaption parameter adjustment method for the automobile advanced driver assistance system is simple in principle and is easy to realize, and the practical value is high.

Description

technical field [0001] The invention relates to an ADAS system, in particular to an adaptive parameter adjustment method in an automobile advanced driving assistance system. Background technique [0002] With the popularity of cars and the increasing level of technology, advanced driver assistance systems (ADAS) have been popularized in many high-end cars. In the actual ADAS system, there are generally functions such as collision warning and car following warning. Collision warning is an early warning issued in advance when the system judges that a collision (person or vehicle) is about to occur. In this situation, the driver must react immediately to avoid a possible collision. Car following warning is an early warning message sent when the distance between the vehicle and the vehicle ahead in the same lane is less than a certain set value (usually converted into time based on speed). Relatively speaking, follow-up warning is less urgent and dangerous than collision warn...

Problems solved by technology

[0005] The purpose of the present invention is to provide a self-adaptive parameter adjustment method in an advanced driving assistance system of an automobile, so as to solve the problem in the prior art that the alarm threshold of the ADAS system needs to be manually set by the user in order to satisfy the user's own driving habits and cause its alarm function to be greatly reduced question
