Description

Technical Field

[0001] The present invention relates to the technical field of device detection, and in particular to a state detection method, device and vehicle of a vehicle light prompt control device. Background Art

[0002] The vehicle turning prompt control device refers to a device that is turned on when the vehicle turns to alert the front, rear, left, and right vehicles and pedestrians to pay attention, and it mainly includes a turn signal and a light control handle. By switching the light control handle to different gears (left turn gear, right turn gear and off gear), the turn signals in different directions can be lit to achieve the purpose of reminding vehicles / pedestrians to pay attention. For example: if the light control handle is switched to the left turn gear, the turn signal on the left side of the vehicle will light up, prompting the vehicle / pedestrian that the vehicle is about to turn left. The current traditional method for detecting the gear position of the light control handle is to detect the resistance value of the light control handle, determine which gear resistance interval the resistance value falls into, and determine the gear position of the light control handle based on the judgment result. However, in actual applications, due to poor contact of components and other reasons, it may happen that although the resistance value of the light control handle is detected to fall into the resistance interval of a certain gear, the actual gear position of the light control handle is inconsistent with this gear. For example: the actual gear position of the light control handle is the left turn gear (the turn signal on the left side of the vehicle is on), but the user has not switched the gear position, but it is detected that the resistance value of the light control handle falls into the resistance range of the right turn gear, causing the turn signal on the right side of the vehicle to light up, thereby increasing the driving risk of the vehicle.

[0112] Some embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0113] In the description of the present invention, "module" and "processor" may include hardware, software or a combination of the two. A module may include hardware circuits, various suitable sensors, communication ports, and memories, and may also include software parts, such as program codes, or a combination of software and hardware. The processor may be a central processing unit, a microprocessor, an image processor, a digital signal processor, or any other suitable processor. The processor has data and / or signal processing functions. The processor may be implemented in software, hardware, or a combination of the two. Non-temporary computer-readable storage media include any suitable medium that can store program codes, such as a magnetic disk, a hard disk, an optical disk, a flash memory, a read-only memory, a random access memory, and the like. The term "A and / or B" means all possible combinations of A and B, such as only A, only B, or A and B. The term "at least one A or B" or "at least one of A and B" has a similar meaning to "A and / or B", and may include only A, only B, or A and B. The singular terms "one" and "the" may also include plural forms.

[0114] Here we first explain some terms involved in the present invention.

[0115] The vehicle light prompt control device refers to a device capable of switching and controlling the vehicle lights, such as a light control handle. The vehicle lights include but are not limited to: left turn signal, right turn signal, low beam, high beam, overtaking light and fog light. In an embodiment of the present invention, the vehicle light prompt control device may include a steering gear switching module, which may be configured to switch the left turn signal (left turn signal) and the right turn signal (right turn signal) through gear switching, and output the gear resistor corresponding to the switched gear after the gear switching, that is, when the left turn signal is turned on (for example: the left turn signal is turned on), the right turn signal is turned on (for example: the right turn signal is turned on) and the right turn signal is turned off, gear resistors with different resistance values ​​are output respectively. In one embodiment, the steering gear switching module is provided with resistors with different resistance values, and different gears are respectively connected to resistors with different resistance values ​​(gear resistors). After the gear switching, the corresponding gear resistors can be connected, so that the steering gear switching module can output the corresponding gear resistor.

[0116] At present, the traditional method for detecting the gear position of the light control handle is mainly to detect the resistance value output by the light control handle, determine which gear resistance interval the resistance value falls into, and determine the gear position of the light control handle according to the judgment result. However, in actual applications, the light control handle may be detected to fall into the resistance interval of a certain gear due to poor contact of electronic components (for example, the gold finger fixed installation in the PCB board is unstable, resulting in poor contact between the gold finger and the PCB board), but the actual gear position of the light control handle is inconsistent with this gear position. For example, the actual gear position of the light control handle is the left turn gear position (the left turn signal is on), but when the user does not switch the gear position, it is detected that the resistance value of the light control handle falls into the resistance interval of the right turn gear position, causing the right turn signal to light up, thereby increasing the driving risk of the vehicle.

[0117] In an embodiment of the present invention, the normal resistance jump sequence of the vehicle light prompt control device during normal operation can be obtained based on the gear resistance corresponding to each gear during the gear switching process of the steering gear switching module when the vehicle light prompt control device is operating normally, and then the actual resistance jump sequence can be obtained based on the gear resistance output by the steering gear switching module in actual application, and finally the normal resistance jump sequence and the actual resistance jump sequence are compared and analyzed. If the two are consistent, it indicates that the vehicle light prompt control device has not failed; if the two are inconsistent, it indicates that the vehicle light prompt control device has failed. Specifically, in an embodiment of the present invention, first, after detecting that the gear resistance output by the steering gear switching module belongs to the gear resistance of the preset steering prompt start gear or the gear resistance of the preset steering prompt close gear, the first resistance jump sequence (actual resistance jump sequence) of the currently detected gear resistance can be obtained based on the gear resistance historical data and the currently detected gear resistance. Then, based on the comparison result of the first resistance jump sequence with the preset second resistance jump sequence (normal resistance jump sequence), it is determined whether the vehicle light prompt control device has a fault; wherein, the preset second resistance jump sequence is the resistance jump sequence obtained by the gear resistor corresponding to each gear in the preset gear switching sequence (the gear switching sequence of the steering gear switching module when the vehicle light prompt control device is operating normally).

[0118] Through the above steps, when it is detected that the gear resistor output by the steering gear switching module falls into the resistance range of the gear resistor of a certain steering prompt start gear (for example, the start gear of the right turn signal) or the steering prompt close gear, it is not directly determined that the gear position of the steering gear switching module is the gear position corresponding to this gear resistor. Instead, when the jump sequence of the gear resistor is consistent with the normal resistance jump sequence, it is determined that the actual gear position of the steering gear switching module is the gear position corresponding to this gear resistor (the steering gear switching module is not faulty), which overcomes the defect in the prior art that the gear position of the light control handle is misjudged due to the inconsistency between the gear position corresponding to the resistance value detection result of the light control handle and the actual gear position of the light control handle.

[0119] See attached Figure 1 , Figure 1 FIG. 1 is a flow chart showing the main steps of a method for detecting the state of a vehicle light prompt control device according to an embodiment of the present invention. Figure 1 As shown, the state detection method of the vehicle light prompt control device in the embodiment of the present invention mainly includes the following steps:

[0120] Step S101: collecting the gear position resistance output by the steering gear position switching module in the vehicle light prompt control device.

[0121] In this embodiment, the specific structure / function of the vehicle light prompt control device, steering gear switching module and gear resistor are the same as the vehicle light prompt control device, steering gear switching module and gear resistor in the aforementioned term explanation. For the sake of brevity, they will not be repeated here.

[0122] Step S102: If the gear resistor is a gear resistor of a preset turn prompt start gear or a gear resistor of a preset turn prompt close gear, a first resistance jump sequence of the gear resistor is obtained according to gear resistor history data and the gear resistor.

[0123] The turn signal start gear position refers to the gear position that controls the left turn signal or the right turn signal to be turned on when the steering gear switch module controls the switch of the left turn signal and the right turn signal through the gear switch. If the gear position is switched to the left turn signal start gear position, the vehicle light signal control device will control the vehicle to turn left (for example, control the left turn signal to be turned on); if the gear position is switched to the right turn signal start gear position, the vehicle light signal control device will control the vehicle to turn right (for example, control the right turn signal to be turned on). The turn signal off gear position refers to the gear position that controls the left turn signal and the right turn signal to be turned off when the steering gear switch module controls the switch of the left turn signal and the right turn signal through the gear switch.

[0124] The preset gear resistance of the steering prompt start gear refers to the gear resistance output by the steering gear switch module after the gear is switched to the steering prompt start gear (left steering prompt start gear and right steering prompt start gear) when the vehicle light prompt control device is operating normally without any faults. The preset gear resistance of the steering prompt close gear refers to the gear resistance output by the steering gear switch module after the gear is switched to the steering prompt close gear when the vehicle light prompt control device is operating normally without any faults.

[0125] Step S103: judging whether a vehicle light prompt control device fails according to a comparison result of the first resistance jump sequence and a preset second resistance jump sequence.

[0126] The preset second resistance jump sequence refers to the resistance jump sequence obtained by the gear resistors corresponding to each gear in the preset gear switching sequence (the gear switching sequence of the steering gear switching module when the vehicle light prompt control device is operating normally).

[0127] Through the above steps S101 to S103, when the embodiment of the present invention detects that the gear resistor output by the steering gear switching module falls into the resistance range of the gear resistor of a certain steering prompt start gear (for example: the start gear of the right turn signal) or the steering prompt close gear, it will not directly determine that the gear position of the steering gear switching module is the gear position corresponding to this gear resistor, but when the jump sequence of the gear resistor is consistent with the normal resistance jump sequence, it determines that the actual gear position of the steering gear switching module is the gear position corresponding to this gear resistor (the steering gear switching module is not faulty), thereby overcoming the defect in the prior art that the gear position of the light control handle is misjudged due to the inconsistency between the gear position corresponding to the resistance value detection result of the light control handle and the actual gear position of the light control handle.

[0128] The above steps S102 and S103 are further explained below.

[0129] In an optional implementation of step S102 of the embodiment of the present invention, the first resistance jump sequence of the gear resistors may be obtained according to the following steps:

[0130] Step S1021: According to the historical data of the gear resistance, the gear resistance output by the steering gear switching module before it jumps to the currently detected gear resistance is obtained.

[0131] Step S1022: Obtain a first resistance jump sequence according to the gear resistance obtained in step S1021 (the gear resistance output by the steering gear switching module before it jumps to the currently detected gear resistance) and the currently detected gear resistance.

[0132] An example: If the "currently detected gear resistance" is the gear resistance R of the left turn prompt start gear 左 , and "the gear resistance output by the steering gear switching module before it jumps to the currently detected gear resistance" is the gear resistance R of the right steering prompt start gear 右 , then the first resistance jump sequence of "currently detected gear resistance" is: from R 左 Jump to R 右 (R 左 →R 右 ) in the order of .

[0133] In this embodiment, after the gear resistance output by the steering gear switching module is collected, the collected resistance can be immediately stored to form gear resistance historical data, so that the first resistance jump sequence of the gear resistance can be quickly and accurately analyzed according to the gear resistance historical data, thereby facilitating accurate status analysis of the vehicle light prompt control device.

[0134] In an optional implementation of step S103 of the embodiment of the present invention, it can be determined whether the vehicle light prompt control device fails according to the following steps: if the first resistor jump sequence is consistent with the preset second resistor jump sequence, it is determined that the vehicle light prompt control device has not failed. If the first resistor jump sequence is inconsistent with the second resistor jump sequence, it is determined that the vehicle light prompt control device has failed and outputs fault warning information.

[0135] In one embodiment, if the parameter R is used 左 , R 右 and R 停 The gear resistors of the left turn prompt start gear, the right turn prompt start gear and the turn prompt off gear respectively represent the gear resistors of the left turn prompt start gear, the gear resistors of the right turn prompt start gear and the gear resistors of the turn prompt off gear. Then the preset second resistor jump sequence may include a first jump sequence and a second jump sequence. The first jump sequence refers to the gear resistors according to R 左 , R 停 and R 右 The order of jump (R 左 →R 停 →R 右 ) order, the second jump order refers to the gear resistance according to R 右 , R 停 and R 左 The order of jump (R 右 →R 停 →R 左In this embodiment, if the first resistor jump sequence is consistent with any one of the first jump sequence and the second jump sequence, it is determined that the first resistor jump sequence is consistent with the preset second resistor jump sequence. If the first resistor jump sequence is inconsistent with both the first jump sequence and the second jump sequence, it is determined that the first resistor jump sequence is inconsistent with the preset second resistor jump sequence.

[0136] In one embodiment, if the parameter R is used 左 , R 右 and R 停 The gear resistors of the left turn prompt start gear, the right turn prompt start gear and the turn prompt off gear respectively represent the gear resistors of the left turn prompt start gear, the gear resistors of the right turn prompt start gear and the gear resistors of the turn prompt off gear. Then the preset second resistor jump sequence may include a third jump sequence and a fourth jump sequence. The third jump sequence refers to the gear resistors according to R 停 To R 左 The order of jump (R 停 →R 左 ) order, the fourth jump order refers to the gear resistance in accordance with R 停 To R 右 The order of jump (R 停 →R 右 In this embodiment, if the first resistor jump sequence is consistent with any one of the third jump sequence and the fourth jump sequence, it is determined that the first resistor jump sequence is consistent with the preset second resistor jump sequence. If the first resistor jump sequence is inconsistent with both the third jump sequence and the fourth jump sequence, it is determined that the first resistor jump sequence is inconsistent with the preset second resistor jump sequence.

[0137] In one embodiment, if the parameter R is used 左 , R 右 and R 停 The gear resistors of the left turn prompt start gear, the right turn prompt start gear and the turn prompt off gear are represented respectively. Then the preset second resistor jump sequence may include a fifth jump sequence and a sixth jump sequence. The fifth jump sequence refers to the gear resistors in accordance with R 左 To R 停 The order of jump (R 左 →R 停 ) order, the sixth jump order refers to the gear resistance in accordance with R 右 To R 停 The order of jump (R 右 →R 停In this embodiment, if the first resistor jump sequence is consistent with any one of the fifth jump sequence and the sixth jump sequence, it is determined that the first resistor jump sequence is consistent with the preset second resistor jump sequence. If the first resistor jump sequence is inconsistent with both the fifth jump sequence and the sixth jump sequence, it is determined that the first resistor jump sequence is inconsistent with the preset second resistor jump sequence.

[0138] Based on the above terminology explanation, it can be known that the steering gear switching module can be configured to output the gear resistance corresponding to the switched gear after the gear is switched, that is, when controlling the left turn prompt to be turned on (for example: controlling the left turn signal to be lit), controlling the right turn prompt to be turned on (for example: controlling the right turn signal to be lit), and controlling the steering prompt to be turned off, the gear resistance of different resistance values ​​will be output respectively. If it is determined that the gear resistance is neither the gear resistance of the preset steering prompt start gear nor the gear resistance of the preset steering prompt off gear, then it can be determined that the vehicle light prompt control device may have a fault, causing this gear resistance to be different from the gear resistance (R 左 , R 右 and R 停 ) are not consistent.

[0139] In one embodiment, in addition to performing status detection on the vehicle light prompt control device according to the above-mentioned embodiments described in steps S101 to S103, it is also possible to detect whether the gear resistance output by the steering gear switching module after the gear switching is inconsistent with the gear resistance corresponding to each gear, and determine whether the vehicle steering prompt control device has a fault based on the detection result. Specifically, Figure 1 The state detection method of the vehicle steering prompt control device shown in the figure may also include step S104. In this embodiment, step S104 mainly includes: determining whether the gear resistance output by the steering gear switching module belongs to the preset abnormal resistance; if it belongs to the preset abnormal resistance, determining that the vehicle light prompt control device has a fault and outputting a fault warning message. Among them, the preset abnormal resistance includes the gear resistance (R 左 , R 右 ) and the gear resistance (R 停 ), that is, a resistance value that is inconsistent with the gear resistance corresponding to each gear. In one implementation, step S104 may be performed before step S101. If it is determined in step S104 that the vehicle light prompt control device has no fault, step S101 is performed. If it is determined that the vehicle light prompt control device has a fault, the fault reminder information is directly output and the subsequent steps S101 to S103 are not performed.

[0140] Further, in the embodiment of the present invention, when it is determined that the vehicle light prompt control device has a fault, it is also possible to use the resistance jump sequence comparison method to determine whether the fault of the vehicle light prompt control device has been resolved. Specifically, in one embodiment, after step S102 and / or step S103 and / or step S104, a step S105 for determining whether the fault has been resolved may be included. In this embodiment, step S105 may specifically include:

[0141] Step S1051: collecting the gear resistance output by the steering gear switching module, and obtaining the third resistance jump sequence of the gear resistance according to the collection result.

[0142] In this implementation, the third resistor jump sequence can be obtained according to the following steps:

[0143] After determining that the vehicle light prompt control device has a fault, the gear resistance output by the steering gear switching module is collected, and the resistance value before and after each gear resistance jump is obtained according to the collection result, and the third resistance jump sequence is obtained according to each resistance value obtained. An example: If after determining that the vehicle light prompt control device has a fault, it is detected that the gear resistance has jumped twice, according to the collection result of the gear resistance, the gear resistance before and after the first jump is R 左 and R 停 , the gear resistance before and after the second jump is R 停 and R 右 , it can be concluded that the third resistor jump sequence is according to R 左 , R 停 and R 右 Jump in sequence (R 左 →R 停 →R 右 ) in the order of 左 , R 停 and R 右 They respectively represent the gear resistance of the left turn prompt start gear, the gear resistance of the right turn prompt start gear, and the gear resistance of the turn prompt off gear.

[0144] Step S1052: judging whether the vehicle light prompt control device has cleared the fault according to the comparison result of the third resistor jump sequence and the preset fourth resistor jump sequence.

[0145] The preset fourth resistor jump sequence refers to the sequence in which the gear resistors corresponding to a turn prompt start gear, a turn prompt off gear, and another turn prompt start gear are sequentially jumped. If "a turn prompt start gear" is a left turn prompt start gear, then "another turn prompt start gear" may be a right turn prompt start gear; if "a turn prompt start gear" is a right turn prompt start gear, then "another turn prompt start gear" may be a left turn prompt start gear.

[0146] If we use the parameter R 左 , R 右 and R 停 The gear resistors of the left turn prompt start gear, the right turn prompt start gear and the turn prompt off gear respectively represent the gear resistors of the left turn prompt start gear, the gear resistors of the right turn prompt start gear and the gear resistors of the turn prompt off gear. Then the preset fourth resistor jump sequence may include the seventh jump sequence and the eighth jump sequence. The seventh jump sequence refers to the gear resistors according to R 左 , R 停 and R 右 Jump in sequence (R 左 →R 停 →R 右 ) order, the eighth jump order refers to the gear resistance according to R 右 , R 停 and R 左 Jump in sequence (R 右 →R 停 →R 左 ). In this embodiment, if the third resistor hopping sequence is consistent with any one of the seventh hopping sequence and the eighth hopping sequence, it is determined that the third resistor hopping sequence is consistent with the preset fourth resistor hopping sequence. If the third resistor hopping sequence is inconsistent with both the seventh hopping sequence and the eighth hopping sequence, it is determined that the third resistor hopping sequence is inconsistent with the preset fourth resistor hopping sequence.

[0147] In this embodiment, if the third resistor jump sequence is consistent with the preset fourth resistor jump sequence, it can be determined that the fault of the vehicle light prompt control device is resolved and the fault warning information is stopped; if the third resistor jump sequence is inconsistent with the fourth resistor jump sequence, the fault warning information continues to be output.

[0148] In an embodiment of the present invention, if multiple failures of the vehicle light prompt control device are detected within a certain period of time, then it can be determined that a relatively serious failure may occur in the vehicle light prompt control device, such as a failure that cannot be overcome by automatic adjustment of the device. Therefore, before executing the fault relief judgment step, the number of multiple failures of the vehicle light prompt control device can be obtained, and whether a relatively serious failure has occurred in the vehicle light prompt control device can be determined based on the number of failures, and whether the fault relief judgment step needs to be executed. Specifically, in one implementation, the following steps can be performed before step S105: obtaining the number of failures of the vehicle light prompt control device determined within a preset detection cycle (for example: 1min); determining whether the number is greater than or equal to a preset number threshold (for example: 3 times); if greater than or equal to the number threshold, the fault relief judgment step (step S105) is not executed; if less than the number threshold, the fault relief judgment step (step S105) is executed.

[0149] It should be pointed out that although the various steps in the above embodiments are described in a specific order, those skilled in the art can understand that in order to achieve the effects of the present invention, different steps do not have to be performed in such an order. They can be performed simultaneously (in parallel) or in other orders. These changes are within the scope of protection of the present invention.
