[0002] During actual use, traditional twin-engine (or auxiliary engine) sanitation vehicles are faced with the situation of repeated switching between driving conditions, operating conditions and idling conditions. Due to the rapid change in load at the switching moment, the circuit voltage in the entire system will suddenly change, causing impact on the circuit. In severe cases, it will directly damage the component assembly and even cause a major accident.

[0003] Traditional twin-engine (or dual-engine) sanitation vehicles rely on the engine to drive their powertrain to perform their respective functions.

[0051] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only 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 this application.

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

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

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

[0056] Step S10: upon receiving the operating mode change instruction, obtaining the current actual engine speed and the target speed carried by the operating mode 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 current working condition of the vehicle is a driving condition, and the actual speed of the engine under the current vehicle driving condition 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 current working condition of the vehicle is an idle operating condition, and the current vehicle speed 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 upper-mounted operation target signal 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 that voltage stabilization control is performed on the vehicle.

[0060] Specifically, 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, 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] Exemplarily, the target speed and actual speed are input into the preset voltage regulation system master controller. The preset voltage regulation system master controller compares the target speed with the preset speed. If the target speed is less than the preset speed, the target speed is output to the engine ECU, which issues a command to achieve the target speed, thereby achieving the target vehicle speed through the chassis module. If the target speed is greater than the preset speed, the preset voltage regulation system master controller calculates the actual speed, the current power corresponding to the target speed, and the target power, and inputs these to the preset voltage regulation controller. The preset voltage regulation controller calculates the upper and lower limits of the current voltage corresponding to the current power, the target voltage corresponding to the target power, and the upper and lower limits of the voltage band with the current voltage as the median, and compares them. If the target voltage does not exceed the current voltage band, the voltage regulation controller returns the target power to the voltage regulation system master controller. The master controller outputs the target speed to the engine ECU, which issues a command to achieve the target speed, thereby achieving the target vehicle speed through the chassis module. If the target voltage exceeds the current voltage band, voltage regulation control is determined to be performed 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 the preset segmentation rules, and the obtained first segmented speed is obtained as the first target segmented speed.

[0064] Specifically, obtaining the first target segmented speed based on the actual speed and the target speed includes: obtaining the current power value corresponding to the actual speed and the target power value corresponding to the target speed respectively based on the actual speed and the target speed; obtaining the 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 current power value and target power value are calculated by the voltage regulator controller based on the input actual speed and target speed, respectively. By presetting the database and querying the current power value and target power value in the preset database, a power curve between the current power value and the target power value is obtained. For example, by querying the preset database through the current power value and the target power value, a corresponding power curve with the current power value and the target power value as the interval in the database is obtained. 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 main 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 target segmented speed corresponding to the first segmented voltage is obtained. 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 ranked highest among the multiple segmented voltages 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 the corresponding second target segmented speed based on the second segmented voltage; adjusting the actual speed based on 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, the 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, thereby completing voltage stabilization control of the vehicle.

[0071] Exemplarily, the vehicle's actual speed is adjusted using the first target speed segment. After the actual speed is adjusted, it is determined whether the adjusted actual speed is consistent with the target speed. If so, voltage stabilization control of the vehicle is completed. If not, the second target speed segment is obtained and the adjusted actual speed is further adjusted until the adjusted actual speed is consistent with the target speed, thereby completing voltage stabilization control of the vehicle.

[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 to perform voltage stabilization control on the vehicle, 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, so as to complete voltage stabilization control of the vehicle, which solves the technical problem in the related art that the upper-mounted voltage stabilizer 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 in FIG, the voltage stabilization control method for a single-engine sanitation vehicle includes:

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

[0075] Exemplarily, when a vehicle receives a working condition change command, it obtains the current actual engine speed and the target speed carried by the working condition change command. For example, if the current vehicle working condition is a driving condition, the actual engine speed under the current vehicle driving condition is obtained. When a driving condition command is received, the driving condition needs to be changed to an operating condition, and the target speed for the operating condition carried in the working condition change command is obtained. For example, if the current vehicle working condition is an idle operating condition and the current vehicle speed is 0, the engine ECU directly inputs the current engine speed to the voltage stabilization system controller as the current vehicle actual speed. When the working condition change command is received, the upper body operation signal sensor transmits a specific upper body operation target signal to the voltage stabilization system controller, and the voltage stabilization system 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 that voltage stabilization control is performed on the vehicle.

[0078] Specifically, 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, 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] Exemplarily, the target speed and actual speed are input into the preset voltage regulation system master controller. The preset voltage regulation system master controller compares the target speed with the preset speed. If the target speed is less than the preset speed, the target speed is output to the engine ECU, which issues a command to achieve the target speed, thereby achieving the target vehicle speed through the chassis module. If the target speed is greater than the preset speed, the preset voltage regulation system master controller calculates the actual speed, the current power corresponding to the target speed, and the target power, and inputs these to the preset voltage regulation controller. The preset voltage regulation controller calculates the upper and lower limits of the current voltage corresponding to the current power, the target voltage corresponding to the target power, and the upper and lower limits of the voltage band with the current voltage as the median, and compares them. If the target voltage does not exceed the current voltage band, the voltage regulation controller returns the target power to the voltage regulation system master controller. The master controller outputs the target speed to the engine ECU, which issues a command to achieve the target speed. If the target voltage exceeds the current voltage band, it is determined that the vehicle will be subjected to voltage regulation control.

[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 the preset segmentation rules, and the obtained first segmented speed is obtained as the first target segmented speed.

[0082] Specifically, obtaining the first target segmented speed based on the actual speed and the target speed includes: obtaining the current power value corresponding to the actual speed and the target power value corresponding to the target speed respectively based on the actual speed and the target speed; obtaining the 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 current power value and target power value are calculated by the voltage regulator controller based on the input actual speed and target speed, respectively. By presetting the database and querying the current power value and target power value in the preset database, a power curve between the current power value and the target power value is obtained. For example, by querying the preset database through the current power value and the target power, a corresponding power curve with the current power value and the target power value as the interval in the database is obtained. 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 main 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 target segmented speed corresponding to the first segmented voltage is obtained. 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 ranked highest among the multiple segmented voltages 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 the corresponding second target segmented speed based on the second segmented voltage; adjusting the actual speed based on 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, the 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.

[0088] Step S104: adjusting the actual speed of the current engine based on the first target segmented speed, wherein adjusting the actual speed of the current engine includes increasing or decreasing the actual speed of the current engine;

[0089] Step S105: comparing the adjusted actual engine speed with the target speed;

[0090] Step S106: If the actual speed of the engine after adjustment is consistent with the target speed, the voltage stabilization control of the vehicle is completed.

[0091] Exemplarily, the actual speed of the current engine is adjusted based on the first target segment speed, wherein adjusting the actual speed of the current engine includes increasing or decreasing the actual speed of the current engine; comparing the actual speed of the adjusted engine with the target speed; if the actual speed of the adjusted engine is consistent with the target speed, completing the voltage stabilization control of the vehicle.

[0092] Step S107: If the adjusted actual speed is inconsistent with the target speed, determining whether to perform voltage stabilization control on the vehicle based on the adjusted actual speed and the target speed;

[0093] Step S108: if it is determined to perform voltage stabilization control on the vehicle, obtaining a third target segmented speed according to the adjusted actual speed and the target speed;

[0094] Step S109: adjusting the adjusted actual speed according to the third target segmented speed so that the adjusted actual speed is consistent with the target speed, thereby completing voltage stabilization control of the vehicle.

[0095] For example, if the actual speed after adjustment is inconsistent with the target speed, it is determined whether to perform voltage stabilization control on the vehicle based on the actual speed after adjustment and the target speed; if it is determined to perform voltage stabilization control on the vehicle, the third target segmented speed is obtained based on the actual speed after adjustment and the target speed; the actual speed after adjustment is adjusted according to the third target segmented speed so that the actual speed after adjustment is consistent with the target speed, thereby completing the voltage stabilization control of the vehicle.

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 working conditions.
