Bend driving anti-turnover early warning control system and method for liquid tank vehicle

Abstract

The invention discloses a bend driving anti-turnover early warning control system and method for a liquid tank vehicle. The system comprises a GPS positioning module, a liquid level height acquisition module, a parameter storage module, an operation module, a decision-making module, an alarm module and a throttle control module. The method comprises the steps of collecting vehicle position and direction data through the GPS positioning module; acquiring the height of liquid in a liquid tank when the vehicle is still through the liquid level height acquisition module; calculating and obtaining a critical speed when the vehicle turns over through the operation module; through the decision-making module, comparing the critical speed and a driving speed, and determining the state of the vehicle; the alarm module and the throttle control module receive information of the decision-making module and conduct alarming and throttle control. By the adoption of the bend driving anti-turnover early warning control system and method for the liquid tank vehicle, when the bend driving speed of the liquid tank vehicle is relatively high, early warning can be provided for a driver, the vehicle speed can be controlled by controlling a throttle, and the purposes are achieved that the vehicle is prevented from turning over and the safety of personal and the vehicle is ensured.

Description

technical field [0001] The invention relates to the technical field of automobile driving safety, and more specifically relates to a rollover prevention warning control system and method for liquid tank trucks running on curved roads. Background technique [0002] When the liquid tanker is loaded with liquid goods, the vehicle has a large mass and a high center of gravity, the left and right wheel bases are relatively small relative to the vehicle width and the height of the center of gravity, and the lateral stability is poor; Under the influence of acceleration, the liquid in the liquid tank tilts and the position of the center of gravity changes. Compared with loading solid cargo, the risk of rollover is higher, and rollover accidents are more likely to occur. Liquid tank trucks loaded with flammable, explosive and highly toxic oils are also potentially highly dangerous. Once a rollover accident occurs and the liquid leaks, it will cause serious environmental pollution an...

[0002] When the liquid tanker is loaded with liquid goods, the vehicle has a large mass and a high center of gravity, the left and right wheel bases are relatively small relative to the vehicle width and the height of the center of gravity, and the lateral stability is poor; Due to the influence of acceleration, the liquid in the liquid tank tilts, and the position of the center of gravity changes. Compared with loading solid cargo, the risk of rollover is higher, and rollover accidents are more likely to occur

Liquid tank trucks loaded with flammable, explosive and highly toxic oils are also potentially highly dangerous. Once a rollover accident occurs and the liquid leaks, it will cause serious environmental pollution and traffic jams, seriously endangering life and property losses
