Rollover prevention control method and system of emergency vehicle for rescue

Abstract

The invention relates to an emergency vehicle rollover prevention control method for rescue and a control system thereof. The emergency vehicle rollover prevention control method comprises the following steps: S1, constructing an emergency vehicle rollover prevention control system; s2, calculating a non-stumbling type rollover index RI of the emergency vehicle running on the structured road; s3, predicting a whole vehicle rollover index PRI of the emergency vehicle running on the complex road; and S4, judging whether the rollover index of the emergency vehicle exceeds a threshold value or not. According to the invention, two rollover indexes of stumbling type rollover and non-stumbling type rollover are adopted, aiming at the characteristics of different rollover modes, the rollover of the vehicle can be effectively prevented by controlling the action of the actuator in the active suspension; and meanwhile, the front axle active suspension obtains complex road surface excitation information, so that the actuating force of an actuator of the active suspension on the rear axle of the emergency vehicle can be predicted in advance, and the impact of road surface excitation on rear axle wheels can be effectively relieved, so that the influence of road surface excitation on vehicle rollover is reduced, and the safety of the emergency rescue vehicle is improved.

Description

technical field [0001] The invention belongs to the technical field of vehicle control, and particularly relates to an emergency vehicle rollover prevention control method for rescue and a control system thereof. Background technique [0002] my country's land terrain and road conditions are complex and diverse, and natural disasters occur frequently. Multi-axle and heavy-load emergency rescue vehicles are the main equipment for land rescue. In the process of emergency rescue, especially when driving on damaged unstructured roads, rollover occurs. Accidents occur from time to time, greatly delaying the rescue time and reducing the rescue efficiency. Therefore, it is urgent to take necessary protective measures to protect the safety of rescue workers and improve rescue efficiency. [0003] There are many reasons for vehicle rollover, which are mainly divided into two types: trip-over rollover and non-trip-over rollover. For example, Chinese patent CN202010133753.5 discloses ...

Problems solved by technology

For example, Chinese patent CN202010133753.5 discloses a control method for vehicle anti-rollover active tilting, but it is only suitable for non-stumbling rollovers and cannot perceive road surface information; A changed rollover warning method, which is applicable to two forms of rollover, but only considers the information of the whole vehicle under the road excitation, and does not consider the different influence of the road excitation on the front and rear axle wheels of the vehicle
