[0080] See Figure 6 , is the flow chart of the first embodiment of the anti-skid control method of the electric wheel dump truck provided by the present invention, and the method includes:

[0081] S601. Determine whether the electric wheel dump truck is slipping according to the wheel speed of the electric wheel dump truck. Specifically, the slipping state of the electric wheel dump truck generally includes two types, one is the slipping of the left rear wheel, and the other is the slipping of the right rear wheel. It can be judged according to any suitable method known to those skilled in the art whether the left rear wheel is slipping, the right rear wheel is slipping, the left and right rear wheels are slipping simultaneously, or both the left and right rear wheels are not slipping. Of course, it is also possible that the speeds of the left front wheel and the right front wheel are much higher than the left rear wheel and the right rear wheel respectively. Currently, the...

[0087] See Figure 7 , is the flow chart of the second embodiment of the anti-skid control method of the electric wheel dump truck provided by the present invention, the method includes:

[0088] S701. Detect the speed of each wheel of the electric wheel dump truck.

[0089] S702. Calculate the speed difference v between the left front wheel and the right front wheel 左前 , the speed difference v between the left rear wheel and the left front wheel 左 , the speed difference v between the right front wheel and the left front wheel 右前 , and the speed difference v between the right rear wheel and the right front wheel 右 .

[0090] S703. According to v 左前 Compute left wheel steering compensation c 左 , and according to v 右前 Calculation of right wheel steering compensation c 右 . Specifically, according to v 左前 , the wheel spacing between the left front wheel and the right front wheel, and the wheel spacing between the left front wheel and the left rear wheel to calculate the ...

Abstract

The embodiment of the invention discloses a skidding resistance control method and device of an electric-wheel dumper. The method includes the steps that whether the electric-wheel dumper skids or not is judged according to the wheel speed of the electric-wheel dumper; when it is determined that the electric-wheel dumper skids, torque compensation amount is calculated according to the wheel speed and is sent to torque regulators of the electric-wheel dumper so that corresponding wheel motors are controlled by the torque regulators to adjust the speeds of wheels correspondingly driven by the wheel motors. By judging whether the wheels of the electric-wheel dumper skid or not and compensating for the torque of the motors corresponding to the skidding wheels when it is determined that the wheels of the electric-wheel dumper skid, the problem that the wheels skid can be safely and effectively solved, the control precision is high, and the skidding resistance effect is good.

Description

technical field [0001] The invention relates to the field of vehicle control, in particular to an anti-skid control method and device for an electric wheel dump truck. Background technique [0002] The electric wheel dump truck is a large-scale transportation vehicle integrating engine, generator, electric motor, hydraulic system and electric control system. It has the advantages of high efficiency, large transportation capacity and good economy. With the improvement of mining demand and the development of industrial technology, large-scale electric wheel dump trucks have become an ideal transportation tool for open-pit mines with an annual mining capacity of more than 10 million tons and large-scale water conservancy construction projects. [0003] However, due to the high cost of the electric wheel dump truck, its safety performance requirements are relatively high. For electric wheel dump trucks, slipping is very likely to cause safety accidents. The anti-skid control s...
