Abstract

The invention provides a truck rollover early warning device and method. By analyzing the actual gravity center height, gravity center horizontal position, the whole vehicle gravity center lateral deviation and the traveling speed of a truck, a front steering wheel turning angle threshold value is obtained and compared with the turning angle of a steering wheel operated by a driver, a control unit obtains a risk state discreet value R according to comparison between the actual steering wheel turning angle and the front steering wheel turning angle threshold value, when the risk state discreet value R is beyond the safety range, the control unit gives out a signal, a buzzer gives out an alarm sound, the driver is reminded to safely operate, the rollover risk of the truck is reduced, and the driver safety is improved.

Description

technical field [0001] The invention relates to a vehicle safety warning method, in particular to a truck rollover risk warning device and method. Background technique [0002] With the continuous development of my country's automobile industry and the improvement of road traffic facilities, the speed of automobiles continues to increase, resulting in a large number of traffic accidents, causing casualties and huge economic losses. Therefore, the safety of automobile driving is more and more concerned by people. Pay attention to. Some vehicles, such as trucks, medium and heavy-duty trucks, heavy-duty semi-trailers, etc., are prone to rollover accidents when turning at high speed and when the diameter of the curve is small due to their high center of mass position, large mass and volume. The loss caused by the rollover accident is serious, which is an important issue in the research field of road traffic safety and vehicle safety. For example, Chinese Patent Publication No. ...
