Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle testing, in particular to a method and device for determining matching of fuses and wires for vehicles, equipment and computer readable storage medium. BACKGROUND

[0002] In the whole vehicle development process, the whole vehicle wiring harness is the core carrier of power and signal transmission, and its design rationality is directly related to the safety, reliability and economy of the vehicle. Among them, the selection of fuses and wire diameters is the core link of wiring harness design: fuses play a key role in circuit overcurrent protection and need to accurately fuse to cut off the circuit when short circuit, overload and other faults occur; the wire diameter determines the current carrying capacity, voltage drop and mechanical strength of the wire, and needs to meet the requirements of long-term stable transmission of electric energy without overheating. The selection of the two needs to be closely combined with the load characteristics, environmental conditions and safety standards of the whole vehicle, and is the basis for ensuring the normal operation of the whole vehicle electrical system. Currently, the selection of fuses and wire diameters in the whole vehicle wiring harness design mainly relies on the experience and manual calculation of designers, and the process presents significant complexity and limitations: on the one hand, the parameter system for selection is complex. On the other hand, manual calculation and table lookup are prone to errors and low efficiency. In addition, the verification process of the selection result further increases the design pressure. If the selection is found to be improper during testing, the calculation and selection need to be performed again, forming a cycle of "design - verification - rework", especially under the background of accelerating the iteration speed of vehicle models and the shortage of human resources, the low efficiency and high fault risk of the traditional selection mode have become a prominent problem restricting the progress of whole vehicle development. Therefore, the existing fuse and wire diameter selection mode relying on manual calculation and experience table lookup has been difficult to meet the requirements of modern whole vehicle wiring harness design for accuracy and efficiency, and it is urgent to simplify the selection process and reduce human errors through technical means to improve design quality and development efficiency.

DETAILED DESCRIPTION

[0016] In order for those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0017] First, some technical terms in the present application are explained and described in order to facilitate the understanding of the present application by those skilled in the art.

[0018] In order to make the purpose, technical solutions and advantages of the present application more clear, the embodiments of the present application will be described in further detail below in conjunction with the drawings.

[0019] In a first aspect, the embodiments of the present application provide a method for determining the matching of fuses and wires for vehicles.

[0020] In an embodiment, referring to Figure 1 , Figure 1 A flowchart schematic diagram of the first embodiment of the method for determining the matching of fuses and wires for vehicles in the present application is shown. As Figure 1 shown, the method for determining the matching of fuses and wires for vehicles includes: Step S10: receiving the input instruction of the user on the database matching interface, and obtaining the load current value, the peak current and the duration, the environmental temperature and the loop length carried by the input instruction; For example, as Figure 2 shown, the input instruction of the user is received on the data matching interface, which includes a load current input box, a peak current and duration input box, an environmental temperature input box and a loop length input box, a fuse selection output box, a wire selection output box, a short circuit test output box and an overload test output box, and a one-key generation button, a DV verification button and a reset button. For example, the input instruction of the user is received, and the load current value, the peak current and the duration, the environmental temperature and the loop length carried by the input instruction are obtained.

[0021] Step S20: When a one-key generation instruction is detected, a target fuse type is determined according to the load current value and the ambient temperature; For example, when a one-key generation instruction of a motor of a user is detected, a target fuse type is determined according to a load current value and an ambient temperature. For example, when a one-key generation button is clicked by a user, a corresponding fuse ambient temperature correction coefficient is obtained according to an ambient temperature, and a target fuse type is determined according to the load current value and the fuse ambient temperature correction coefficient. For example, a fuse rated current is calculated according to the load current value and the fuse ambient temperature correction coefficient, and a corresponding target fuse type is determined according to the fuse rated current.

[0022] Specifically, the target fuse type is determined according to the load current value and the ambient temperature, including: determining a fuse ambient temperature correction coefficient based on the ambient temperature; calculating a fuse rated current based on the load current value, the fuse ambient temperature correction coefficient and a first preset formula; obtaining a corresponding fuse type based on a preset fuse type table and the fuse rated current; obtaining a pulse energy value of the fuse type; and if the pulse energy value of the fuse type is less than or equal to a preset pulse energy value, the fuse type is taken as the target fuse type.

[0023] For example, the pulse energy value of the fuse type is obtained as Figure 3The preset fuse temperature correction coefficient graph is queried based on the ambient temperature to obtain a fuse ambient temperature correction coefficient corresponding to the ambient temperature in the preset fuse temperature correction coefficient graph. For example, when the ambient temperature is 60 degrees, the fuse ambient temperature correction coefficient corresponding to 60 degrees in the preset fuse temperature correction coefficient graph is queried to be 95%. The fuse rated current is calculated by obtaining the first preset formula fuse rated current = load current ÷ (fuse ambient temperature correction coefficient × 0.7). The preset fuse type table is obtained, and the fuse type corresponding to the fuse rated current greater than or equal to the fuse rated current is queried in the preset fuse type table. The fuse type is at least one. If there is more than one fuse type, the pulse energy values of the fuse types are obtained, and the pulse current I2T and the fuse melting I2T of each fuse type are obtained from the preset fuse data graph. The pulse energy values of each fuse type are obtained according to the obtained second preset formula, the pulse current I2T and the fuse melting I2T. For example, the second preset formula relative pulse energy value = pulse current I2T ÷ fuse melting I2T is obtained. After obtaining the pulse energy values of each fuse type, the pulse energy values of each fuse type are compared with the preset pulse energy value, and the fuse type with a pulse energy value less than or equal to the preset pulse energy value is taken as the target fuse type. If there are multiple target fuse types, the fuse type with the minimum pulse energy value is taken as the target fuse type, and the target fuse type is displayed in the fuse selection output box.

[0024] Step S30: determining a wire selection value according to the load current value and the ambient temperature; For example, the third preset formula target allowable current value = allowable current at wire working ambient temperature × 0.7 (safety factor) is obtained, and the target allowable current value is compared with the load current value. If the target allowable current value is greater than or equal to the load current value, the wire selection value corresponding to the target allowable current is determined from the preset wire selection table, and the wire selection value is displayed in the wire selection output box.

[0025] Step S40: when the DV verification instruction is detected, short circuit verification and overload verification are performed according to the load current value, the peak current and the duration, the ambient temperature, the loop length, the wire selection value and the target fuse type, to determine whether the wire selection value and the target fuse type match.

[0026] Exemplarily, when detecting the DV verification instruction input by the user, short circuit verification and overload verification are performed according to the load current value, the peak current and the duration, the ambient temperature, the loop length, the wire type value and the target fuse type, to determine whether the wire type value and the target fuse type match. If it is determined that the wire type value and the target fuse type do not match, the input instruction of the user is received again in the database matching interface, to obtain the target load current value, the target peak current and the duration, the target ambient temperature and the target loop length carried by the input instruction; when detecting a one-key generation instruction, the current target fuse type is determined according to the target load current value and the target ambient temperature; the current wire type value is determined according to the target load current value and the target ambient temperature; when detecting a DV verification instruction, short circuit verification and overload verification are performed according to the target load current value, the target peak current and the duration, the target ambient temperature, the target loop length, the current wire type value and the current target fuse type, to determine whether the current wire type value and the current target fuse type match.

[0027] Specifically, the short circuit verification and the overload verification are performed according to the load current value, the peak current and the duration, the ambient temperature, the loop length, the wire type value and the target fuse type, to determine whether the wire type value and the target fuse type match, including: performing short circuit verification according to the wire type value and the target fuse type, to obtain a target loop length causing short circuit; determining whether the wire type value and the target fuse type have a short circuit risk according to the target loop length and the loop length; performing overload verification according to the wire type value and the target fuse type, to obtain combination data; determining whether the wire type value and the target fuse type have an overload risk according to the combination data verification of the load current value, the peak current and the duration, the ambient temperature and the loop length; and if it is determined that the wire type value and the target fuse type do not have the short circuit risk and the overload risk, it is determined that the wire type value and the target fuse type match.

[0028] For example, according to the wire selection value and the target fuse type, short circuit verification is performed to obtain a target loop length causing the short circuit, and the target loop length is compared with the loop length to determine whether the wire selection value and the target fuse type exist a short circuit risk. If the target loop length is less than or equal to the loop length, it is determined that the wire selection value and the target fuse type exist the short circuit risk. If the target loop length is greater than the loop length, it is determined that the wire selection value and the target fuse type do not exist the short circuit risk. According to the wire selection value and the target fuse type, overload verification is performed to obtain combination data. For example, data in which the wire selection value passes the overload verification and data in which the wire selection value passes the overload verification are combined to obtain the combination data. The combination data is verified against the load current value, the peak current and the duration, the environmental temperature and the loop length, that is, whether the combination data contains the load current value, the peak current and the duration, the environmental temperature and the loop length. If yes, it is determined that the wire selection value and the target fuse type do not exist the overload risk. If no, it is determined that the wire selection value and the target fuse type exist the overload risk. If it is determined that the wire selection value and the target fuse type do not exist the short circuit risk and the overload risk, it is determined that the wire selection value and the target fuse type match, for example, as shown in FIG. 8, the wire selection value and the target fuse type do not exist the short circuit risk and the overload risk. Figure 4

[0029] In this embodiment, the load current value, the peak current and the duration, the environmental temperature and the loop length carried by the input instruction of the user are obtained through the database matching interface. When a key generation instruction is detected, the target fuse type is determined according to the load current value and the environmental temperature. The wire selection value is determined according to the load current value and the environmental temperature. When a DV verification instruction is detected, short circuit verification and overload verification are performed according to the load current value, the peak current and the duration, the environmental temperature, the loop length, the wire selection value and the target fuse type to determine whether the wire selection value and the target fuse type match. The technical problems of low accuracy and low efficiency of the existing fuse and wire diameter selection mode in the related art which relies on manual calculation and experience table lookup are solved, and the accuracy and efficiency of the matching of the fuse and the wire are improved.
