Embodiment 1

[0045] A kind of electric actuator control method, see figure 1 , which is a flow chart of the steps of the electric actuator control method, the electric actuator control method specifically includes:

[0046] Step S100: When the valve plate 420 in the electric actuator 410 rotates, judge whether the electric actuator 410 is blocked according to the rotation state of the valve plate 420;

[0047] Step S200: When the electric actuator 410 is blocked, control the valve plate 420 to perform cleaning rotation.

[0048] In a specific embodiment, it should be specifically noted that, before step S100 and step S200, it is necessary to control the valve plate 420 to rotate according to steps S310-S350.

[0049] The electric actuator 410 controls the valve plate 420 to perform a rotary state, and the specific operation steps are:

[0050] Step S310: Acquiring information on the rotation angle of the control valve plate 420 .

[0051] Step S320: Analyzing the angle information to ob...

Embodiment 2

[0060] see figure 2 , is the concrete step of judging whether the electric actuator 410 is blocked according to the rotation state of the valve plate 420 in step S100, including:

[0061] Step S110: Obtain the position information of the valve plate 420 rotating.

[0062] Step S120: Analyzing the position information to obtain the position reached by the valve plate 420 when it rotates.

[0063] Step S130: According to the position reached by the valve plate 420, it is judged whether the electric actuator 410 is blocked.

[0064] In a specific embodiment, the judging step S100 is judged according to the rotation process of the valve plate 420 controlled by steps S310-S350. Therefore, step S110 must be performed first to obtain the position information of the valve plate 420, and then the step S120, by analyzing the information, the specific position reached by the valve plate 420 is obtained. The position reached during the rotation of the valve plate 420 must be between t...

Embodiment 3

[0066] In a specific embodiment, step S130 is specifically, according to the rotation state of the valve plate 420, when the valve plate 420 rotates forward and the valve plate 420 cannot reach the second mechanical stop position according to the first torque, it is determined as The electric actuator 410 is blocked; according to the rotation state of the valve plate 420, when the valve plate 420 rotates in the reverse direction and the valve plate 420 cannot reach the first mechanical stop position according to the second torque, it is determined that the electric actuator 410 is blocked.

[0067] Further, when the valve plate 420 rotates in the forward direction, if the valve plate 420 cannot rotate from the first mechanical stop position to the second mechanical stop position during the forward rotation process, it means that the first mechanical stop position and the second mechanical stop position There is a blockage between the two mechanical stop positions, which makes t...

Abstract

The invention provides an electric actuator, an electric actuator control method and a commercial vehicle. The electric actuator control method comprises the steps that under the condition that a valve block in an electric actuator rotates, whether the electric actuator is blocked or not is judged according to the rotating state of the valve block; and under the condition that the electric actuator is blocked, and the valve block is controlled to perform cleaning rotation. The rotation of the valve block in the electric actuator specifically comprises the following steps that angle information for controlling the rotation of the valve block is acquired; the angle information is analyzed to obtain that the rotation direction of the valve block is forward or reverse; the valve block is controlled to rotate; and the valve block is controlled to rotate repeatedly at least twice according to the target number of times. The problem of blockage in a commercial vehicle exhaust emission system is solved, and the technical effect that the commercial vehicle exhaust emission system can automatically clean blockage is achieved.

Description

technical field [0001] The present invention relates to the technical field of electric actuators, in particular, to electric actuators, a control method thereof, and a commercial vehicle. Background technique [0002] With the development of commercial vehicle technology, the application of electric actuators in commercial vehicles is becoming more and more extensive. As environmental protection and energy conservation are paid more and more attention, electric actuators are also used in the exhaust gas of commercial vehicles. processing system. [0003] The exhaust gas of commercial vehicles often contains a large amount of lead and some particulate matter, which can easily cause blockage of the exhaust system in the exhaust emission system of commercial vehicles. At this time, through the valve plate in the electric actuator, the particulate matter in the exhaust emission process of commercial vehicles can be cleaned to prevent the exhaust system from clogging in the exh...
