Detailed Description
First, the related working principle of the automobile truck-mounted crane is explained.
The vehicle-mounted power take-off can be divided into single-switch power take-off and double-switch power take-off according to structural differences of a vehicle gearbox. The single-switch power taking means that the power taking control can be realized through only one power taking switch no matter in a driving working condition or a stopping working condition. The double-switch power taking means that the driving and parking working conditions respectively need to be controlled to start the power taking function through different power taking switches, the control switch under the driving working condition is called a driving power taking switch, and the control switch under the parking working condition is called a parking power taking switch.
Referring to fig. 1, fig. 1 is a schematic diagram of a stopping power take-off control circuit, a DPF regeneration prohibition control circuit, and an engine forced start control circuit.
As shown in fig. 1, an on-board crane of a truck-specific vehicle generally takes force from a transmission case in a case where the vehicle is stopped in place, thereby operating the crane. For the truck-mounted crane with double-switch power taking, the truck-mounted crane mainly comprises a traveling power taking electromagnetic valve and a parking power taking electromagnetic valve which are connected in parallel, wherein the traveling power taking electromagnetic valve and the parking power taking electromagnetic valve are respectively connected with a power supply, a traveling power taking switch is arranged between the traveling power taking electromagnetic valve and the power supply, and a parking power taking electromagnetic valve is arranged between the parking power taking electromagnetic valve and the power supply.
For a dual-switch power-take truck crane, the related power-take control method is that the gearbox operating lever is firstly placed in a neutral position, and then the vehicle is started, because the existing commercial vehicles are all designed with neutral starting logic for safety; then closing a parking power take-off switch to enable a parking power take-off electromagnetic valve to be attracted, at the moment, the parking power take-off electromagnetic valve enables high-pressure air from an air storage cylinder to be communicated with an air passage at an idle gear position of a secondary box of the gearbox, and a pressure difference is utilized to enable a synchronizer of the secondary box to be in neutral gear, so that a vehicle cannot run; then, the driving power take-off switch is closed to enable the driving power take-off electromagnetic valve to be attracted, and the driving power take-off electromagnetic valve is communicated with a power take-off working gas path on the gearbox by high-pressure air from the air storage cylinder, so that the power take-off works in gear; finally, according to the actual working condition, the transmission is put into the gear of the required low gear area, at the moment, the power takeoff still works in gear, and the vehicle can keep in-situ still because the gearbox auxiliary box is positioned in neutral, so that operators can sit on the crane to operate the crane arm.
However, this force extraction method is not perfect in terms of safety and convenience.
In terms of safety, with the implementation of new national sixth (national sixth stage motor vehicle pollutant emission standard) emission regulations, the current vehicle emission level in the market is gradually upgraded to national sixth, and the national sixth vehicle model has a DPF (Diesel Particulate Filte) passive regeneration function, which is usually automatically started according to the sensor signal of the emission aftertreatment system in the running process of the engine, and the purpose of reducing carbon deposition in the emission aftertreatment device is achieved by automatically increasing the engine rotation speed to increase the exhaust temperature and the exhaust quantity. Once the DPF passive regeneration function happens in the working process of the vehicle-mounted crane, the engine speed is greatly increased in a short time, the running power of the crane arm is directly influenced, and the engine speed is automatically increased, so that the vehicle-mounted crane is not controlled by manual operation, cargo swing or tipping and the like can be possibly caused, and the vehicle-mounted crane has a large risk on personal and property safety.
In some special use environments, in order to close the DPF passive regeneration function for a short period of time, the state six vehicles are generally provided with a control circuit for the DPF regeneration prohibition function, and the DPF regeneration prohibition switch is manually and actively closed to close the DPF regeneration function, but the control circuit and the power take-off control circuit are mutually independent circuits, and the DPF regeneration prohibition switch and the power take-off switch are mutually independent switches. Therefore, the problem that the truck crane operator forgets to close the DPF regeneration inhibition switch before the operation possibly occurs, the DPF is passively regenerated and started in the working process of the truck crane, and the engine speed is automatically increased in a short time, is not controlled by people, and can cause safety risks such as cargo swing or tipping.
In terms of convenience, when an operator of the crane wishes to remotely start the vehicle again at the crane station after completing one-wheel crane operation and remotely extinguishing the vehicle, the vehicle cannot be started because the gearbox control lever is not in neutral at this time, the operator must leave the crane and return to the vehicle cab to re-engage neutral in order to start the vehicle, then start the power take-off according to the related power take-off control method described above, and finally return to the crane station. On the basis of the related power taking control method, an operator cannot remotely start the vehicle on the crane station, and great inconvenience is brought to the work of the operator.
Existing engines typically have a forced start function, i.e. the engine can be forced started by simply screwing the ignition lock into the start gear for a long time (this time can be calibrated) regardless of whether it is neutral or not. After the crane operator finishes one-wheel crane operation and remotely extinguishes the vehicle, the operator can select to remotely start the vehicle at the crane station through a forced starting function, but when the parking power take-off switch is not closed or is opened by misoperation of other people, the gearbox auxiliary box is in a neutral state, and once the operator remotely and forcedly starts the vehicle under the condition, the vehicle can travel with gears under the condition that a cab is unmanned due to the fact that the operator is positioned on the crane, and great safety threat is caused to the operator positioned at the crane station and personnel around the vehicle.
According to the above situation, the vehicle must be started when the transmission is in neutral, and the power take-off must be realized under the condition that the transmission is engaged, and the two logics are mutually contradictory, so that under the existing power take-off control method, the operator cannot realize the remote starting function of the vehicle. When the operation is stopped and the vehicle is flameout, operators need to return to the cab of the vehicle from the crane station, the parking power is restarted according to the existing power taking control method, and then the operator returns to the crane station from the cab to operate, so that great inconvenience is brought to the operation process of the truck-mounted crane. When an operator attempts to employ the engine forced start function, it is necessary to ensure that the park take-off switch is closed to ensure that the gearbox sub-tank is in neutral. However, in the existing power take-off control method, because the power take-off control circuit and the engine forced starting circuit are independent circuits, the parking power take-off switch cannot be guaranteed to be in a closed state when the vehicle is started remotely, once crane operators remotely and forcedly start the vehicle when the parking power take-off switch is not closed or is opened by misoperation of other people, the vehicle can travel with gears under the condition that a cab is unmanned, and great safety threat is caused to operators positioned at a crane station and surrounding operators of the vehicle.
Based on the above reasons, the related power take-off control method has potential safety hazards in terms of safety and has an optimization space in terms of convenience, so that the embodiment of the application provides an automobile truck-mounted power take-off control system, method and automobile to solve the above problems.
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

For example, some operations/steps may be further divided, combined, or partially combined, so that the order of actual execution may be changed according to actual situations.
Some embodiments of the present application are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.

a second switch connected in parallel with the DPF regeneration inhibiting switch and configured to be closed and opened in synchronization with the first switch to control DPF regeneration inhibition when closed.
It should be noted that the second switch is connected in parallel with the DPF regeneration inhibiting switch, and the second switch may perform the same function as the DPF regeneration inhibiting switch, that is, control the DPF regeneration inhibiting switch to be closed. Meanwhile, the first switch and the second switch for controlling the power take-off of the crane are synchronously closed and opened, namely, when the first switch is closed to enable the crane to start the power take-off work, the second switch is synchronously closed to control the DPF to inhibit regeneration, and when the first switch is opened to enable the crane to stop the power take-off work, the second switch is synchronously opened to cancel the inhibition of DPF regeneration. Therefore, DPF regeneration is forbidden in the whole process of stopping the crane of the crane in the power taking operation process, the phenomenon that the crane arm is not controlled due to the fact that the engine speed is increased due to DPF regeneration starting during the power taking operation of the crane is avoided, the stability and the safety of the crane in the operation process are improved, and the personal safety and the property safety of related personnel in the operation process of the crane are ensured.
It is worth noting that the second switch is connected in parallel with the DPF regeneration inhibition switch through a wire. According to the embodiment of the application, the first end of the second switch is connected with the first end of the DPF regeneration inhibition switch through the lead, and the second end of the second switch is connected with the second end of the DPF regeneration inhibition switch through the lead, so that the second switch is connected with the DPF regeneration inhibition switch in parallel. The second switch and the regeneration inhibition switch after being connected in parallel have the same function, namely, the PDF is controlled to inhibit regeneration when the second switch is closed, and the DPF operates normally when the second switch is opened. The second switch is independent of the DPF regeneration inhibition switch, and the DPF regeneration inhibition switch is not affected, so that DPF regeneration can still be inhibited when the DPF regeneration inhibition switch is closed.
In some embodiments, the electromagnetic valve in the power take-off control system of the automobile truck-mounted crane comprises a driving power take-off electromagnetic valve and a parking power take-off electromagnetic valve, the first switch is arranged between the power supply and the parking power take-off electromagnetic valve, and the first switch is configured to control the power supply to be connected with or disconnected from the parking power take-off electromagnetic valve.

As a preferred embodiment, the first switch and the second switch form a double contact switch.
Specifically, the original parking power take-off switch is a single-contact switch, the original single-contact switch can be replaced by a double-contact switch, the parking power take-off switch is connected with one pair of contacts of the parking power take-off switch and kept unchanged, and the other pair of contacts are respectively connected with two ends of the contacts of the DPF regeneration inhibition switch to serve as a second switch. Under this kind of connected mode, when the parking power take-off function is opened to the crane, the parking power take-off switch is in the closed state, and the second switch is also closed simultaneously, and the second switch has put through DPF simultaneously and has forbidden regeneration circuit, has realized that the crane is forbidden DPF regeneration in whole journey in the power take-off operation in-process, avoids taking place engine rotational speed automatic promotion in crane handling article in-process, has avoided personal, property safety hidden danger that goods swing or turn on one's side etc. brought, has improved crane in-process stability and security for personnel's that the crane in-process is relevant personal safety and property safety are ensured.

It is worth to say that, in the embodiment of the application, the automatic reset remote control switch is arranged on the forced starting signal transmission port of the engine, and the parking power take-off switch is associated with the forced starting signal transmission port of the engine through the automatic reset remote control switch, so that a control loop of the parking power take-off switch, the automatic reset remote control switch and the forced starting signal transmission port of the engine is formed. On the premise that the parking force taking switch is closed, the automatic reset remote control switch receives the remote control signal and is closed, and then a closed loop is formed to conduct the forced engine starting signal transmission port, so that the forced engine starting signal is transmitted to the engine controller, and the engine is forced to be started. If the parking power take-off switch is in an off state, the automatic reset remote control switch receives the remote control signal and cannot form a closed loop after being closed, so that the forced starting signal transmission port of the engine cannot be conducted, and the engine cannot be forced started. The vehicle can be remotely started only when the parking power take-off switch is in a closed state, the potential safety risk of running of the vehicle under the condition that a cab is unmanned due to human errors before the crane operator remotely and forcedly starts the vehicle is eliminated, and the vehicle is remotely started under the condition of safety protection.
