Problems solved by technology

[0003] Wherein, when the above-mentioned transport vehicle is driving on a curve, if the radius of the curve is too small, the speed of the transport vehicle is too fast at this time. Due to the heavy weight of the transport vehicle and the large inertia of the transport vehicle in the process of carrying the transport vehicle, the transport vehicle has There is a risk of sideslip or rollover, and there are hidden dangers to the safety of the transport vehicle when cornering. Therefore, it is necessary to control the speed of the transport vehicle on the curve.

Embodiment 1

[0058] A rollover prevention method for transport vehicles such as figure 1 shown, including the following steps:

[0059] Step S100, acquire the vehicle driving route and the status information of each curve in the vehicle driving route, wherein the status information of the curve carries the position of the starting point of the curve, the curvature value of the curve and the position of the end point of the curve .

[0060] According to the technical solution defined in step S100, specifically, as image 3 As shown, the vehicle includes a car body and a transport tank set on the car body. Wheels are installed on the car body through the axles. An air suspension is arranged between the wheel axles and the car body for support. The front part of the car body is provided with a cab. , it is worth noting that the car body is equipped with an electronic controller, a vehicle navigation system, a GPS locator and a vehicle EBS system, and the electronic controller is connected t...

Embodiment 2

[0090] like image 3As shown, the vehicle includes a car body and a transport tank set on the car body. Wheels are installed on the car body through the axles. An air suspension is arranged between the wheel axles and the car body for support. The front part of the car body is provided with a cab. , it is worth noting that the car body is equipped with an electronic controller, a vehicle navigation system, a GPS locator and a vehicle EBS system, and the electronic controller is connected to the vehicle navigation system, GPS locator and There is a wireless transmission module, and the electronic controller is used to collect various data of the vehicle, and then can send various data to the management server through the wireless transmission module, and the management server is connected to a display screen for displaying various data.

[0091] The GPS locator is used to locate the current driving position of the vehicle. The on-board EBS system is used to activate the on-boar...

Abstract

The invention discloses a rollover prevention method and system for a transport vehicle, and the method comprises the following steps of obtaining a vehicle driving route and state information of each curve in the vehicle driving route, wherein the state information of the curve carries a starting point position of the curve, a curvature value of the curve and an ending point position of the curve; when the current driving position of the vehicle is within a first preset distance from the starting point of the front curve, limiting the maximum speed of the vehicle to a first speed; calculating a vehicle speed critical point value corresponding to the curvature value of the front curve according to the curvature value of the front curve, and judging whether a first vehicle speed is greater than the vehicle speed critical point value of the front curve; if so, limiting the maximum speed of the vehicle to the speed critical point value of the front curve when the current driving position of the vehicle from the starting point position of the front curve is within a second preset distance. The rollover prevention method and system for the transport vehicle has the characteristic of improving the conering safety of the transport vehicle.

Description

technical field [0001] The invention relates to the technical field of transport vehicle control, in particular to an anti-rollover method and system for transport vehicles. Background technique [0002] The transportation vehicles involve petroleum liquefied gas transportation vehicles and dangerous goods transportation vehicles. The above transportation vehicles need to maintain the safety of transportation at all times during the transportation process. [0003] Wherein, when the above-mentioned transport vehicle is driving on a curve, if the radius of the curve is too small, the speed of the transport vehicle is too fast at this time. Due to the heavy weight of the transport vehicle and the large inertia of the transport vehicle in the process of carrying the transport vehicle, the transport vehicle has There is a risk of sideslip or rollover, and there are hidden dangers to the safety of the transport vehicle when cornering. Therefore, it is necessary to control the spe...
