Description

Technical Field

[0001] The invention relates to the technical field of automobile electronic and electrical grounding, and in particular to a method and device for determining the electrical grounding form of a cab. Background Art

[0002] In the vehicle electrical system, grounding is as important as the power distribution system. As part of the vehicle circuit, grounding is the return channel for all loads or the discharge channel for induced current. With the development of intelligence and networking, there are more and more controllers in the cab. If the grounding performance does not meet the design requirements, it will cause the electrical load function to fail, and seriously endanger the safety of people and vehicles. Ideally, each electronic and electrical component needs to be grounded separately nearby, but this will result in too many groundings in the vehicle, greatly increasing the complexity of assembly, and increasing the quality and cost of the vehicle. Therefore, this method is not the best choice.

[0003] At present, the electrical grounding of the commercial vehicle cab is in the form of riveted points combined with grounding, with a main grounding wire as the main grounding wire, from the electrical box to the body sheet metal, and the grounding of other controllers, lights, etc. is directly separated from the main grounding wire. Figure 1 As a typical existing case, two electronic and electrical components are first riveted to a main grounding wire and finally grounded through the main grounding wire. Figure 1 In the figure, R1 is the resistance of electronic component 1; L1 is the resistance of the wire from the riveting point to the grounding point; R2 is the resistance of electronic component 2; L2 is the resistance of the wire from electronic component 2 to the riveting point. When only electronic component 1 is working, I1 = U / (L1+R1); when only electronic component 2 is working, I2 = U / (L1+L2+R2); when both electronic components are working, I1+I2 = U / (L1+R1)+U / (L1+L2+R2). At this time, if I2 is significantly greater than I1, the potential difference between electronic component 1 and the grounding will increase greatly, which will affect the operation of electronic component 1. Therefore, the electrical grounding of the cab of commercial vehicles is grounded in the form of riveting points combined with grounding. There may be interference between electronic components, affecting the normal operation of electronic components. Summary of the invention

[0042] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] The embodiment of the present invention provides a method for determining the electrical grounding form of a cab, which can solve the technical problem that the prior art adopts the form of riveting points combined with grounding, and electronic and electrical components may interfere with each other, thus affecting the normal operation of the electronic and electrical components.

[0044] See also Figure 2 As shown, an embodiment of the present invention provides a method for determining the electrical grounding form of a cab, comprising the following steps:

[0045] Step S10, obtaining the peak operating current of each electronic and electrical component. Usually, the manufacturer will give a recommended value for the peak operating current of the electronic and electrical component when the product leaves the factory, and the recommended value can be used as the peak operating current of the corresponding electronic and electrical component.

[0046] Step S20, determining the grounding category of each electronic and electrical component according to the peak operating current of each electronic and electrical component, wherein the grounding category includes electronic grounding and power grounding;

[0047] Determining the grounding category of each electronic and electrical component according to the peak operating current of each electronic and electrical component includes:

[0048] Determine whether the peak current of any electronic component is greater than the preset current threshold:

[0049] If yes, the grounding category of the electronic and electrical component is power grounding;

[0050] If not, the grounding category of the electronic and electrical component is electronic grounding.

[0051] For example, the preset current threshold can be set to 1A. If the peak current of the electronic and electrical component is greater than 1A, the grounding category of the electronic and electrical component can be determined as power grounding; if the peak current of the electronic and electrical component is less than or equal to 1A, the grounding category of the electronic and electrical component can be determined as electronic grounding. For example, the grounding category of the wiper motor and wiper relay is power grounding, and the grounding category of the combination meter and the menu key switch of the meter is electronic grounding.

[0052] Step S30, determining the grounding form according to the grounding category of each electronic and electrical component and the working system in which it is located, wherein the grounding form includes a grounding form of riveted points combined with grounding, a grounding form of wiring pieces combined with grounding, a grounding form of wiring pieces alone grounding, and a grounding form of parallel crimped terminals combined with grounding.

[0053] Figure 3 In order to achieve grounding by combining riveting points with grounding, two electronic and electrical components are first riveted together using a grounding wire, and then connected to a wiring piece and connected to the grounding ground through a grounding wire. Figure 4 In order to achieve grounding by combining a wiring lug with a grounding iron, two electronic and electrical components are first connected to their respective wiring lugs using grounding wires, and then the two wiring lugs are combined at the grounding iron, and finally connected to the grounding iron. Figure 4 In order to ground by combining parallel wire crimping terminals with grounding, two electronic and electrical components are first connected to a wiring piece with grounding wires respectively, and then the wiring piece is connected to the grounding ground at the grounding ground. Figure 3 , Figure 4 and Figure 5 In the diagram, the grounded black circle is regarded as the grounding pad, and the protrusion on the grounding pad is regarded as the wiring lug.

[0054] Specifically, the grounding form is determined according to the grounding category of each electronic and electrical component and the working system in which it is located, including:

[0055] If any two electronic and electrical components belong to the same working system and have the same grounding category, then confirm that the two electronic and electrical components are grounded in the form of riveted points combined with grounding. For example, the menu key switch of the instrument cluster and the instrument meets Figure 3 In the example on the left, the wiper motor and wiper relay meet Figure 3 The example on the right shows that the instrument cluster and the menu key switch of the meter belong to the same working system, and the grounding type of both is electronic grounding, and the wiper motor and wiper relay belong to the same working system, and the grounding type of both is power grounding.

[0056] If any two electronic and electrical components belong to the same working system and their grounding categories are different, it is confirmed that the two electronic and electrical components adopt the grounding form of connecting lugs and grounding. For example, BCM and combination instrument meet Figure 4 In the example on the right, the BCM and the instrument cluster belong to the same operating system, and their grounding types are different.

[0057] If any two electronic and electrical components do not belong to the same working system, and both of them are grounded in electronic grounding, determine whether the difference between their peak working currents is greater than the preset first current difference: if so, the two electronic and electrical components adopt the grounding form of wiring lugs combined with grounding; if not, the two electronic and electrical components adopt the grounding form of parallel crimping terminals combined with grounding. The preset first current difference can be set to 300mA. For example, the retarder and LDWS meet Figure 4 Example on the left, fatigue monitoring and T-BOX meet Figure 5 Example on the left. The retarder and LDWS do not belong to the same working system, and the grounding category of both is electronic grounding. The difference between the peak working currents of the two is greater than the preset first current difference. The fatigue monitoring and T-BOX do not belong to the same working system, and the grounding category of both is electronic grounding. The difference between the peak working currents of the two is not greater than the preset first current difference.

[0058] If any two electronic and electrical components do not belong to the same working system, and both of them are grounded in power type, determine whether the difference between their peak working currents is greater than the preset second current difference: if so, the two electronic and electrical components adopt the grounding form of wiring lugs combined with grounding; if not, the two electronic and electrical components adopt the grounding form of parallel crimping terminals combined with grounding. The preset second current difference can be set to 2A. For example, the driving recorder and the central door lock controller DCM meet Figure 4 In the middle example, the driving recorder and the vehicle terminal display screen meet Figure 5 Middle example. The driving recorder and the central door lock controller DCM do not belong to the same working system, and the grounding category of both is power grounding, and the difference between the peak working currents of the two is greater than the preset second current difference. The driving recorder and the vehicle terminal display screen do not belong to the same working system, and the grounding category of both is power grounding, and the difference between the peak working currents of the two is not greater than the preset second current difference.

[0059] If any two electronic and electrical components do not belong to the same working system and their grounding categories are different, determine whether the difference between their peak working currents is less than the preset third current difference: if so, the two electronic and electrical components adopt the grounding form of the wiring lugs combined with the grounding; if not, the two electronic and electrical components adopt the grounding form of the wiring lugs alone. The preset third current difference can be set to 700mA. For example, the lidar controller and the PEPS controller meet Figure 4In the example on the right, the driving recorder and the fuel sensor are grounded separately using wiring lugs. The LiDAR controller and the PEPS controller do not belong to the same working system, and the grounding categories of the two are different. The difference between the peak working currents of the two is not greater than the preset third current difference. The driving recorder and the fuel sensor do not belong to the same working system, and the grounding categories of the two are different. The difference between the peak working currents of the two is greater than the preset third current difference.

[0060] The method for determining the electrical grounding form of the cab in the embodiment of the present invention first obtains the peak operating current of each electronic and electrical component; then determines the grounding category of each electronic and electrical component according to the peak operating current of each electronic and electrical component; and finally determines the grounding form according to the grounding category of each electronic and electrical component and the working system in which it is located. That is, the present invention divides the grounding category of each electronic and electrical component into electronic grounding and power grounding, and determines the grounding form based on the grounding category of each electronic and electrical component and the working system in which it is located, which can avoid mutual interference between signals as much as possible and ensure that sensitive electronic and electrical components can work normally.

[0061] See also Figure 6 As shown, an embodiment of the present invention further provides a device for determining the electrical grounding form of a cab, comprising: an acquisition unit, a first determination unit, and a second determination unit.

[0062] The acquisition unit is used to acquire the peak operating current of each electronic and electrical component.

[0063] The first determining unit is used to determine the grounding category of each electronic and electrical component according to the peak operating current of each electronic and electrical component, and the grounding category includes electronic grounding and power grounding.

[0064] The second determination unit is used to determine the grounding form according to the grounding category of each electronic and electrical component and the working system in which it is located. The grounding form includes a grounding form of riveted points combined with grounding, a grounding form of wiring pieces combined with grounding, and a grounding form of parallel wire crimping terminals combined with grounding.

[0065] The device for determining the electrical grounding form of the cab in the embodiment of the present invention first obtains the peak operating current of each electronic and electrical component; then determines the grounding category of each electronic and electrical component according to the peak operating current of each electronic and electrical component; and finally determines the grounding form according to the grounding category of each electronic and electrical component and the working system in which it is located. That is, the present invention divides each electronic and electrical component into electronic grounding and power grounding, which can avoid mutual interference between signals as much as possible and ensure that sensitive electronic and electrical components can work normally.
