Abstract

The invention relates to braking process-based dynamic automobile gravity position detector and a method. The device consists of an axle weight, a braking force detector, an axle base measuring device, a wheel base measuring device and a data collection processing system; dynamic gravity detection algorithm is obtained by derivation on the basis of braking process, the device is applied to collect axle weight and braking force signals, axle base signals and wheel base signals, thus being capable of calculating the position of the automotive gravity. Based on the automotive gravity position calculation method, sideslip and rolling-over of vehicles can be analyzed to calculate limiting values of sideslip and rolling-over of vehicles under different road conditions and give out early-warning information to avoid occurrence of traffic accidents. The invention can be widely applied in safety driving control process of various vehicles.

Description

technical field [0001] The invention belongs to a device and method for dynamically detecting the position of the center of gravity of an automobile based on a braking process, and is a method for quickly and effectively detecting the position of the center of gravity of an automobile through the measurement of axle load, braking force, wheelbase and wheelbase. Background technique [0002] Among all traffic accidents, the degree of harm of automobile rollover accidents is second only to automobile collision accidents. In addition to the driver's error in the vehicle rollover, the deviation of many parameters of the vehicle is also an important factor. The center of gravity position of the vehicle is one of the most important and difficult to measure parameters among these parameters. Therefore, the dynamic detection of the position of the center of gravity of the vehicle is of great significance. The position of the center of gravity of the car is usually expressed by the...
