[0051] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0052] First, some technical terms in the present application are explained to facilitate those skilled in the art to understand the present application.

[0053] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0054] In a first aspect, an embodiment of the present application provides a voltage stabilization control method for a single-engine sanitation vehicle.

[0055] In one embodiment, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the voltage stabilization control method for a single-shot sanitation vehicle in this application. Figure 1 As shown, the voltage stabilization control method of a single-engine sanitation vehicle includes:

[0056] Step S10: upon receiving the operating condition change instruction, obtaining the actual speed of the current engine and the target speed carried by the operating condition change instruction;

[0057] Exemplarily, when the vehicle receives a working condition change instruction, the actual speed of the current engine and the target speed carried by the working condition change instruction are obtained. For example, the working condition of the current vehicle is a driving condition, and the actual speed of the engine under the driving condition of the current vehicle is obtained. When the driving condition instruction is received, the driving condition needs to be changed to an operating condition. The target speed of the operating condition carried in the working condition change instruction is obtained. For example, the working condition of the current vehicle is an idle operating condition, and the speed of the current vehicle is 0. The engine ECU directly inputs the current engine speed to the voltage stabilization system master controller as the actual speed of the current vehicle. When the working condition change instruction is received, the upper-mounted operation signal sensor transmits a specific operation target signal of the upper-mounted to the voltage stabilization system master controller, and the voltage stabilization system master controller calculates the target speed required for the operation signal.

[0058] Step S20: determining whether to perform voltage stabilization control on the vehicle according to the actual speed and the target speed;

[0059] Exemplarily, the acquired target speed is compared with the actual speed. If the target speed is greater than the actual speed, or the target speed is less than the actual speed, it is determined to perform voltage stabilization control on the vehicle.

[0060] Specifically, the method of determining whether to perform voltage stabilization control on the vehicle based on the actual speed and the target speed includes: comparing the target speed with a preset speed; if the target speed is greater than the preset speed, inputting the actual speed and the target speed into a preset voltage stabilization system master controller respectively; calculating the current power corresponding to the actual speed and the target power corresponding to the target speed respectively through the preset voltage stabilization system master controller; inputting the current power and the target power into a preset voltage stabilization controller, and obtaining the upper and lower limits of the current voltage of the current power and the target voltage of the target power respectively output by the preset voltage stabilization controller; comparing the upper and lower limits of the current voltage with the target voltage to determine whether to perform voltage stabilization control on the vehicle; if the target voltage exceeds the upper and lower limits of the current voltage, determining to perform voltage stabilization control on the vehicle.

[0061] Demonstratively, the target speed and the actual speed are input into the preset voltage stabilization system master controller, and the target speed is compared with the preset speed by the preset voltage stabilization system master controller. If the target speed is less than the preset speed, the target speed is output to the engine ECU, and the engine ECU issues a command to complete the target speed, and then the target vehicle speed is achieved through the chassis module. If the target speed is greater than the preset speed, the actual speed, the current power corresponding to the target speed, and the target power are calculated by the preset voltage stabilization system master controller and input into the preset voltage stabilization controller, and the upper and lower limits of the current power corresponding to the current voltage and the target voltage corresponding to the target power are calculated by the preset voltage stabilization controller, and the upper and lower limits of the voltage band with the current voltage as the median are compared; if the target voltage does not exceed the voltage band of the current voltage, the voltage stabilization controller returns the target power to the voltage stabilization system master controller, and the master controller outputs the target speed to the engine ECU, and the engine ECU issues a command to complete the target speed, and then the target vehicle speed is achieved through the chassis module. If the target voltage exceeds the voltage band of the current voltage, it is determined to perform voltage stabilization control on the vehicle.

[0062] Step S30: if it is determined to perform voltage stabilization control on the vehicle, obtaining a first target segmented speed according to the actual speed and the target speed;

[0063] Exemplarily, if it is determined that the vehicle is to be subjected to voltage stabilization control, the first target segmented speed is obtained based on the actual speed and the target speed. For example, when the actual speed and the target speed are obtained, the speed difference between the actual speed and the target speed is calculated, and the obtained speed difference is segmented according to a preset segmentation rule, and the obtained first segmented speed is obtained as the first target segmented speed.

[0064] Specifically, the method of obtaining the first target segmented speed based on the actual speed and the target speed includes: respectively obtaining a current power value corresponding to the actual speed and a target power value corresponding to the target speed based on the actual speed and the target speed; obtaining a power curve between the current power value and the target power value based on a preset database; segmenting the power curve to obtain at least one segmented power; and obtaining the corresponding first target segmented speed based on the segmented power.

[0065] Exemplarily, the actual speed and target speed obtained are input into the voltage regulator controller, and the voltage regulator controller calculates the current power value and the target power value based on the input actual speed and target speed, respectively. The power curve between the current power value and the target power value is obtained by presetting a database and querying the current power value and the target power value in the preset database. For example, the current power value and the target power value are queried in the preset database to obtain the corresponding power curve in the database where the current power value and the target power value are intervals. The power curve is divided to obtain at least two segmented powers, and the obtained segmented powers are sorted in order from low to high, and the first segmented power in the sorting is obtained as the first target segmented power. The first target segmented power obtained is input into the voltage regulator controller through the voltage stabilization system master controller, and the voltage regulator controller obtains the output first target segmented speed through the input first target segmented power.

[0066] Specifically, the method of obtaining the corresponding first target segmented speed based on the segmented power includes: obtaining the corresponding segmented voltage based on the segmented power, wherein the segmented voltage is at least two; sorting the multiple segmented voltages in order from low to high, and comparing the first segmented voltage with the upper and lower limits of the current voltage, wherein the upper and lower limits of the current voltage are obtained by calculating the actual speed; if it is determined that the first segmented voltage is within the upper and lower limits of the current voltage, then obtaining the first segmented voltage to obtain the corresponding first target segmented speed.

[0067] Exemplarily, when the segmented power is obtained, the obtained segmented power is input into the voltage regulator controller, and the voltage regulator controller calculates the input segmented power to obtain the corresponding segmented voltage. The multiple segmented voltages are sorted in order from low to high, and the first segmented voltage with the highest ranking among the multiple segmented voltages is compared with the upper and lower limits of the current voltage, wherein the upper and lower limits of the current voltage are obtained by calculating the actual speed. If it is determined that the first segmented voltage is within the upper and lower limits of the current voltage, the first segmented voltage is obtained to obtain the corresponding first target segmented speed. For example, if the first segmented voltage does not exceed the upper and lower limits of the current voltage, the voltage regulator controller returns the first target power corresponding to the first segmented voltage to the voltage stabilization system master controller, and the master controller outputs the first target segmented speed corresponding to the first target power.

[0068] Specifically, after comparing the first segmented voltage with the upper and lower limits of the current voltage, it also includes: if it is determined that the first segmented voltage is not within the upper and lower limits of the current voltage, obtaining a second segmented voltage among the multiple segmented voltages; if it is determined that the second segmented voltage is within the upper and lower limits of the current voltage, obtaining a corresponding second target segmented speed according to the second segmented voltage; adjusting the actual speed according to the second target segmented speed so that the actual speed is consistent with the target speed, so as to complete the voltage stabilization control of the vehicle.

[0069] Exemplarily, if it is determined that the first segmented voltage is not within the upper and lower limits of the current voltage, a second segmented voltage among the multiple segmented voltages is obtained; if it is determined that the second segmented voltage is within the upper and lower limits of the current voltage, the corresponding second target segmented speed is obtained based on the second segmented voltage; the actual speed is adjusted according to the second target segmented speed so that the actual speed is consistent with the target speed to complete the voltage stabilization control of the vehicle.

[0070] Step S40: adjusting the actual speed according to the first target segmented speed so that the actual speed is consistent with the target speed, so as to complete voltage stabilization control of the vehicle.

[0071] Exemplarily, the actual speed of the vehicle is adjusted by obtaining the first target segment speed. After the actual speed is adjusted, it is determined whether the adjusted actual speed is consistent with the target speed. If they are consistent, the voltage stabilization control of the vehicle is completed. If they are inconsistent, the second target segment speed is obtained to adjust the adjusted actual speed again until the adjusted actual speed is consistent with the target speed, and the voltage stabilization control of the vehicle is completed.

[0072] In this embodiment, when an operating condition change instruction is received, the actual speed of the current engine and the target speed carried by the operating condition change instruction are obtained; based on the actual speed and the target speed, it is determined whether to perform voltage stabilization control on the vehicle; if it is determined that the vehicle is to be subjected to voltage stabilization control, a first target segmented speed is obtained based on the actual speed and the target speed; the actual speed is adjusted according to the first target segmented speed to make the actual speed consistent with the target speed to complete voltage stabilization control of the vehicle, thereby solving the technical problem that the upper-mounted voltage stabilizer in the related technology requires a large modification space, has no layout space on the chassis, and is expensive. Therefore, there is an urgent need for a voltage stabilization control method for a single-engine sanitation upper-mounted vehicle, which can achieve segmented adjustment of the engine speed, thereby solving the damage and destruction caused by voltage fluctuations and impacts under complex operating conditions.

[0073] In one embodiment, referring to Figure 2 , Figure 2This is a flow chart of the first embodiment of the voltage stabilization control method for a single-shot sanitation vehicle in this application. Figure 2 As shown, the voltage stabilization control method of a single-engine sanitation vehicle includes:

[0074] Step S101: upon receiving a working condition change instruction, obtaining the actual speed of the current engine and the target speed carried by the working condition change instruction;

[0075] Exemplarily, when the vehicle receives a working condition change instruction, the actual speed of the current engine and the target speed carried by the working condition change instruction are obtained. For example, the working condition of the current vehicle is a driving condition, and the actual speed of the engine under the driving condition of the current vehicle is obtained. When the driving condition instruction is received, the driving condition needs to be changed to an operating condition, and the target speed of the operating condition carried in the working condition change instruction is obtained. For example, the working condition of the current vehicle is an idle operating condition, and the speed of the current vehicle is 0. The engine ECU directly inputs the current engine speed to the voltage stabilization system master controller as the actual speed of the current vehicle. When the working condition change instruction is received, the upper-mounted operation signal sensor transmits a specific operation target signal of the upper-mounted to the voltage stabilization system master controller, and the voltage stabilization system master controller calculates the target speed required for the operation signal.

[0076] Step S102: determining whether to perform voltage stabilization control on the vehicle according to the actual speed and the target speed;

[0077] Exemplarily, the acquired target speed is compared with the actual speed. If the target speed is greater than the actual speed, or the target speed is less than the actual speed, it is determined to perform voltage stabilization control on the vehicle.

[0078] Specifically, the method of determining whether to perform voltage stabilization control on the vehicle based on the actual speed and the target speed includes: comparing the target speed with a preset speed; if the target speed is greater than the preset speed, inputting the actual speed and the target speed into a preset voltage stabilization system master controller respectively; calculating the current power corresponding to the actual speed and the target power corresponding to the target speed respectively through the preset voltage stabilization system master controller; inputting the current power and the target power into a preset voltage stabilization controller, and obtaining the upper and lower limits of the current voltage of the current power and the target voltage of the target power respectively output by the preset voltage stabilization controller; comparing the upper and lower limits of the current voltage with the target voltage to determine whether to perform voltage stabilization control on the vehicle; if the target voltage exceeds the upper and lower limits of the current voltage, determining to perform voltage stabilization control on the vehicle.

[0079] Demonstratively, the target speed and the actual speed are input into the preset voltage stabilization system master controller, and the target speed is compared with the preset speed by the preset voltage stabilization system master controller. If the target speed is less than the preset speed, the target speed is output to the engine ECU, and the engine ECU issues a command to complete the target speed, and then the target vehicle speed is achieved through the chassis module. If the target speed is greater than the preset speed, the actual speed, the current power corresponding to the target speed, and the target power are calculated by the preset voltage stabilization system master controller and input into the preset voltage stabilization controller, and the upper and lower limits of the current power corresponding to the current voltage and the target voltage corresponding to the target power are calculated by the preset voltage stabilization controller, and the upper and lower limits of the voltage band with the current voltage as the median are compared; if the target voltage does not exceed the voltage band of the current voltage, the voltage stabilization controller returns the target power to the voltage stabilization system master controller, and the master controller outputs the target speed to the engine ECU, and the engine ECU issues a command to complete the target speed. If the target voltage exceeds the voltage band of the current voltage, it is determined to perform voltage stabilization control on the vehicle.

[0080] Step S103: if it is determined to perform voltage stabilization control on the vehicle, obtaining a first target segmented speed according to the actual speed and the target speed;

[0081] Exemplarily, if it is determined that the vehicle is to be subjected to voltage stabilization control, the first target segmented speed is obtained based on the actual speed and the target speed. For example, when the actual speed and the target speed are obtained, the speed difference between the actual speed and the target speed is calculated, and the obtained speed difference is segmented according to a preset segmentation rule, and the obtained first segmented speed is obtained as the first target segmented speed.

[0082] Specifically, the method of obtaining the first target segmented speed based on the actual speed and the target speed includes: respectively obtaining a current power value corresponding to the actual speed and a target power value corresponding to the target speed based on the actual speed and the target speed; obtaining a power curve between the current power value and the target power value based on a preset database; segmenting the power curve to obtain at least one segmented power; and obtaining the corresponding first target segmented speed based on the segmented power.

[0083] Exemplarily, the actual speed and target speed obtained are input into the voltage regulator controller, and the voltage regulator controller calculates the current power value and the target power value based on the input actual speed and target speed, respectively. The power curve between the current power value and the target power value is obtained by presetting a database and querying the current power value and the target power value in the preset database. For example, the current power value and the target power are queried in the preset database to obtain the corresponding power curve in the database where the current power value and the target power value are intervals. The power curve is divided to obtain at least two segmented powers, and the obtained segmented powers are sorted in order from low to high, and the first segmented power in the sorting is obtained as the first target segmented power. The first target segmented power obtained is input into the voltage regulator controller through the voltage stabilization system master controller, and the voltage regulator controller obtains the output first target segmented speed through the input first target segmented power.

[0084] Specifically, the method of obtaining the corresponding first target segmented speed based on the segmented power includes: obtaining the corresponding segmented voltage based on the segmented power, wherein the segmented voltage is at least two; sorting the multiple segmented voltages in order from low to high, and comparing the first segmented voltage with the upper and lower limits of the current voltage, wherein the upper and lower limits of the current voltage are obtained by calculating the actual speed; if it is determined that the first segmented voltage is within the upper and lower limits of the current voltage, then obtaining the first segmented voltage to obtain the corresponding first target segmented speed.

[0085] Exemplarily, when the segmented power is obtained, the obtained segmented power is input into the voltage regulator controller, and the voltage regulator controller calculates the input segmented power to obtain the corresponding segmented voltage. The multiple segmented voltages are sorted in order from low to high, and the first segmented voltage with the highest ranking among the multiple segmented voltages is compared with the upper and lower limits of the current voltage, wherein the upper and lower limits of the current voltage are obtained by calculating the actual speed. If it is determined that the first segmented voltage is within the upper and lower limits of the current voltage, the first segmented voltage is obtained to obtain the corresponding first target segmented speed. For example, if the first segmented voltage does not exceed the upper and lower limits of the current voltage, the voltage regulator controller returns the first target power corresponding to the first segmented voltage to the voltage stabilization system master controller, and the master controller outputs the first target segmented speed corresponding to the first target power.

[0086] Specifically, after comparing the first segmented voltage with the upper and lower limits of the current voltage, it also includes: if it is determined that the first segmented voltage is not within the upper and lower limits of the current voltage, obtaining a second segmented voltage among the multiple segmented voltages; if it is determined that the second segmented voltage is within the upper and lower limits of the current voltage, obtaining a corresponding second target segmented speed according to the second segmented voltage; adjusting the actual speed according to the second target segmented speed so that the actual speed is consistent with the target speed, so as to complete the voltage stabilization control of the vehicle.

[0087] Exemplarily, if it is determined that the first segmented voltage is not within the upper and lower limits of the current voltage, a second segmented voltage among the multiple segmented voltages is obtained; if it is determined that the second segmented voltage is within the upper and lower limits of the current voltage, the corresponding second target segmented speed is obtained based on the second segmented voltage; the actual speed is adjusted according to the second target segmented speed so that the actual speed is consistent with the target speed to complete the voltage stabilization control of the vehicle.
