Problems solved by technology
Due to the inaccuracy of human subjective judgment, when the construction vehicle is driving, especially when driving on a sloped road or mountain road, it is very easy to overturn due to the high center of gravity, resulting in safety accidents and poor safety.

The invention discloses an engineering vehicle and a driving control method, device and system of the engineering vehicle. The driving control method comprises the steps of acquiring a road inclination angle acquired by an obliquity sensor and the current driving speed of the engineering vehicle, acquired by a speed sensor; obtaining the minimum safety turning radius according to the road inclination angle, the current driving speed and the determined gravity center position of the engineering vehicle, and obtaining the usual turning radius corresponding to the current driving speed according to the corresponding relation of the statistical driving speed based on daily driving regularity and the usual turning radius; and outputting alarming information when the usual turning radius is less than the minimum turning radius, wherein the alarming information can pre-prompt the driver to reduce the driving speed or increase the turning radius before dangerous accidents happen, therefore, the method can reduce the turning-over probability of the engineering vehicle, caused by turning driving, and can improve the driving safety.
Description
technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a driving control method, device, and system for an engineering vehicle and an engineering vehicle. Background technique [0002] Construction vehicles, especially self-propelled construction vehicles such as mixer trucks and pump trucks, often have structural characteristics such as large mass and high center of gravity due to the needs of engineering construction characteristics. For example, due to the need for mixing function, the mixing tank of the mixer truck often needs to perform mixing operations while the chassis is driving. At this time, the center of gravity of the mixer truck also changes, and the center of gravity rises, and the left and right boundaries between the center of gravity and the vehicle support surface appear. Asymmetry etc. [0003] In the prior art, the engineering vehicle is usually controlled by the driver relying on his own driving e...
