[0038] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, and are not used to limit the scope of the present invention.

[0039] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include at least one of such features. Furthermore, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0040] In the description of the present invention, reference to an "embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute a separate or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the described embodiment may be combined with other embodiments.

[0041] With the continuous upgrading of national and local emission regulations, manufacturers of sub-engine sanitation vehicles face increasing technical difficulties and cost pressures. The market urgently needs solutions that meet regulatory requirements without increasing vehicle costs. Single-engine sanitation vehicles that use chassis engine power as the power source for the upper structure have emerged due to their advantages such as small modification space, low vehicle noise, and low maintenance costs.

[0042] The operating loads of sanitation vehicles are different, and the power input requirements are also different. However, traditional mechanical single-engine sanitation vehicles are limited by the speed ratio of the full-power power take-off. All operating actions are carried out at a constant engine speed, resulting in low vehicle operating efficiency and high fuel consumption.

[0043] In order to solve the above problems, the present invention provides an operation control method for a single-engine sanitation vehicle.

[0044] The specific embodiments are described in detail below:

[0045] A specific embodiment of the present invention discloses an operation control method for a single-engine sanitation vehicle, combined with Figure 1 Come and see, Figure 1 This is a flow chart of an embodiment of the operation control method of a single-engine sanitation vehicle provided by the present invention, including steps S101 to S103, wherein:

[0046] In step S101, the engine power required for vehicle operation is determined based on the vehicle operating conditions, the vehicle pedal signal, and the vehicle speed signal, wherein the vehicle operating conditions include an idle condition and a driving condition;

[0047] In step S102, a first power is determined based on the bodywork operation signal, where the first power is the engine power required for vehicle operation;

[0048] In step S103 , the engine output torque is controlled based on the engine power required for vehicle operation and the first power.

[0049] During implementation, the engine power required for vehicle operation can be determined based on the vehicle's operating conditions, pedal signals, and preferred speed. These operating conditions can include both idling and driving conditions. For example, idling involves garbage loading and unloading, compacting, and other operations, while driving involves sweeping, watering, and dust suppression.

[0050] Then, the engine power (i.e., the first power) required for the vehicle operation can be determined based on the upper load operation signal. The upper load operation signal can be used to indicate the vehicle's current specific operation type, such as garbage loading and unloading, garbage compression, sweeping, watering, dust suppression, and other operations.

[0051] Finally, the engine output torque can be controlled according to the engine power and the first power required for the operation of the vehicle, thereby achieving vehicle operation control.

[0052] Compared with the prior art, the operation control method of a single-engine special sanitation vehicle provided in this embodiment first considers the engine power required for vehicle operation under different working conditions, so that the engine power for vehicle operation can be allocated according to the vehicle working conditions, and then the engine power required for vehicle operation is determined, and the engine power allocated to the specific operation is clarified. Finally, the engine output torque is controlled in combination with the engine power required for vehicle operation and the engine power required for vehicle operation, thereby realizing the operation control of the vehicle. When performing operation control on a single-engine special sanitation vehicle, the present invention takes into account the specific operating conditions, so that the engine output torque can be reasonably controlled, the operation efficiency of the entire vehicle can be improved, and the operation cost of the entire vehicle can be reduced.

[0053] Exemplarily, determining the engine power required for vehicle operation based on the vehicle operating condition, the vehicle pedal signal, and the vehicle speed signal includes:

[0054] When the vehicle operating condition is an idle condition, determining a second power based on a current pedal signal and a vehicle speed signal of the vehicle, the second power being the engine power required for the vehicle to idle;

[0055] When the vehicle operating condition is a driving condition, a third power is determined based on the vehicle's current pedal signal and vehicle speed signal, and a fourth power is determined based on the vehicle's current pedal signal and target vehicle speed signal. The third power is the engine power required for the vehicle to maintain the current vehicle speed, and the fourth power is the engine power required for the vehicle to reach the target vehicle speed.

[0056] Specifically, when determining the engine power required for vehicle operation based on the vehicle operating condition, the vehicle's pedal signal, and the vehicle speed signal, if the vehicle operating condition is an idling condition, the engine power required for idling can be determined as a second power based on the vehicle's current pedal signal and speed signal. If the vehicle operating condition is a driving condition, the engine power required to maintain the vehicle's current speed can be determined as a third power based on the vehicle's current pedal signal and speed signal, and the engine power required to reach the target speed (i.e., the vehicle's operating speed) can be determined as a fourth power based on the vehicle's current pedal signal and the target speed signal. Determining the engine power required for corresponding vehicle operation based on the vehicle operating condition can improve the rationality of subsequent vehicle operation control.

[0057] Exemplarily, controlling the engine output torque based on the engine power required for vehicle operation and the first power includes:

[0058] When the vehicle operating condition is an idle condition, correcting the first power to obtain a fifth power;

[0059] When the second power is greater than or equal to the fifth power, controlling the engine output torque based on the second power;

[0060] When the second power is less than the fifth power, the engine output torque is controlled based on the fifth power.

[0061] Specifically, when the engine output torque is controlled based on the engine power required for vehicle operation and the first power, if the vehicle operating condition is an idle condition, the first power can be corrected considering the system loss to obtain the fifth power, and then the second power and the fifth power are compared, and the engine output torque is controlled according to the comparison result.

[0062] If the second power is greater than or equal to the fifth power, it means that the engine power required for vehicle operation under idle conditions is able to meet the engine power required for vehicle operation, and the engine output torque can be controlled according to the second power; if the second power is less than the fifth power, it means that the engine power required for vehicle operation under idle conditions cannot meet the engine power required for vehicle operation, and the engine output torque can be controlled according to the fifth power.

[0063] Exemplarily, controlling the engine output torque based on the second power includes:

[0064] A first torque is determined based on the second power, and the engine is controlled to transmit mechanical kinetic energy to the generator at the first torque.

[0065] Specifically, when the engine output torque is controlled according to the second power, the first torque can be determined according to the second power, and then the engine is controlled to transmit mechanical kinetic energy to the generator with the first torque. After obtaining the mechanical kinetic energy transmitted by the engine, the generator can convert it into electrical energy and store it for subsequent operations.

[0066] Exemplarily, controlling the engine output torque based on the fifth power includes:

[0067] A second torque is determined based on the fifth power, and the engine is controlled to transmit mechanical kinetic energy to the generator at the second torque.

[0068] Specifically, when the engine output torque is controlled according to the fifth power, the second torque can be determined according to the fifth power, and then the engine is controlled to transmit mechanical kinetic energy to the generator with the second torque. After obtaining the mechanical kinetic energy transmitted by the engine, the generator can convert it into electrical energy and store it for subsequent operations.

[0069] Exemplarily, controlling the engine output torque based on the engine power required for vehicle operation and the first power includes:

[0070] When the vehicle operating condition is a driving condition, the sum of the first power and the third power is corrected to obtain a sixth power, and the sum of the first power and the fourth power is corrected to obtain a seventh power;

[0071] When the sixth power and the seventh power are both less than or equal to the upper limit power of the engine, controlling the engine output torque based on the first power and the fourth power;

[0072] When the sixth power or the seventh power is greater than the upper limit power of the engine, the vehicle operation is stopped.

[0073] Specifically, when controlling the engine output torque based on the engine power required for vehicle operation and the first power, if the vehicle is in a driving condition, the sum of the first and third powers may be corrected to obtain a sixth power, taking into account system losses, and the sum of the first and fourth powers may be corrected to obtain a seventh power. A determination is then made as to whether both the sixth and seventh powers are less than or equal to the engine upper limit power. If so, the engine output torque may be controlled based on the first and fourth powers. If at least one of the sixth and seventh powers is greater than the engine upper limit power, the current engine is no longer able to meet driving and operating requirements, and vehicle operation needs to be stopped to avoid damage to the engine.

[0074] Exemplarily, controlling the engine output torque based on the first power and the fourth power includes:

[0075] determining a third torque based on the first power, and determining a fourth torque based on the fourth power;

[0076] The engine is controlled to transmit mechanical kinetic energy to the generator with the third torque, and to transmit mechanical kinetic energy to the vehicle chassis with the fourth torque.

[0077] Specifically, when the engine output torque is controlled according to the first power and the fourth power, the third torque can be determined according to the first power, and the fourth torque can be determined according to the fourth power. Then, the engine is controlled to transmit mechanical kinetic energy to the generator with the third torque, and to transmit mechanical kinetic energy to the vehicle chassis with the fourth torque, so as to realize the operation of the vehicle under driving conditions.

[0078] The following is a specific application scenario to better illustrate the technical solution of the present invention:

[0079] In response to the defects of the existing technology, the present invention can not only enable modification factories to upgrade vehicle products to meet national emission regulations, but also improve product competitiveness due to the small modification space occupied, low vehicle noise and low repair and maintenance costs.

[0080] Combine Figure 2 Come and see, Figure 2 This is a flow chart illustrating an embodiment of the operation control process of the electronic control system for a single-engine sanitation vehicle provided by the present invention. The electronic control system for a single-engine sanitation vehicle includes a pedal signal sensor, a vehicle speed signal sensor, a bodywork operation signal sensor, an engine ECU, a system master controller, an engine, a full-power power take-off (PTO), a generator module, a generator controller, a chassis module, a bodywork operation controller, and a bodywork operation execution module. The system master controller module is respectively connected to the engine ECU, the generator controller, and the bodywork operation controller; the generator controller is connected to the generator module; the engine ECU is connected to the engine; the engine is respectively connected to the full-power PTO and the chassis module; the full-power PTO is connected to the generator module; the bodywork operation execution module receives instructions from the bodywork operation controller and power provided by the generator module to complete specific operations; the pedal signal sensor, the vehicle speed signal sensor, and the bodywork operation signal sensor are respectively hardwired to the engine ECU and the system master controller for signal interception by the engine ECU and the system master controller.

[0081] The specific working process is as follows:

[0082] 1. Idle operation (i.e. completing various vehicle operations such as garbage loading, garbage compression, garbage unloading, etc.) under idle conditions.

[0083] 1. The pedal signal sensor transmits the current pedal signal to the engine ECU, and the vehicle speed sensor transmits the vehicle speed = 0 signal to the engine ECU. The engine ECU calculates the current pedal depth and the engine idle power P1 required for the corresponding vehicle speed, and inputs this value P1 to the system master controller.

[0084] 2. The upper body operation signal sensor transmits a specific upper body operation signal to the system master controller, and the system master controller calculates the engine power P2 required for this specific operation.

[0085] 3. The system master controller takes into account the system loss and performs weighted calculation on P2 to obtain P3.

[0086] 4. The system master controller compares and calculates P1 and P3. If P1 ≥ P3:

[0087] (1) If P1 ≥ P3, the system master controller calculates the output torque N1 according to the current idle speed R1.

[0088] (2) The system master controller sends the N1 instruction to the engine ECU. After calculation and judgment, the engine ECU provides the required torque to the generator module through the full-power power take-off according to the instruction N1. The generator module converts mechanical kinetic energy into electrical energy and stores energy.

[0089] (3) The system master controller sends the N1 instruction to the generator controller. The generator controller adjusts the generator module according to the N1 instruction and feeds back to the generator controller after completing the N1 instruction. The generator controller then feeds back to the system master controller that the power energy is ready.

[0090] (4) After the system master controller has prepared its energy, it sends instruction N2 to the upper controller. The upper controller adjusts the upper job execution module according to instruction N2 to complete the corresponding job.

[0091] 5. The system master controller compares and calculates P1 and P3. If P1 < P3:

[0092] (1) If P1 < P3, the system master controller dynamically calculates the speed R2 and torque N3 according to the step accuracy of the current idle speed R1 (this accuracy can be defined and adjusted) until the speed R2 and torque N3 meet P3.

[0093] (2) The system master controller sends R2 and N3 instructions to the engine ECU. The engine ECU calculates and judges the instructions and sends them to the engine. The engine coordinates with the chassis module to complete the required speed state for the current operating state according to instruction R2. The engine provides the required torque to the generator module through the full-power power take-off according to instruction N3. The generator module converts mechanical kinetic energy into electrical energy and stores the energy.

[0094] (3) The system master controller sends the N3 instruction to the generator controller. The generator controller adjusts the generator module according to the N3 instruction and feeds back the N3 instruction to the generator controller after completing the N3 instruction. The generator controller then feeds back to the system master controller that the power energy is ready.

[0095] (4) After the system master controller has prepared its energy, it sends instruction N4 to the upper controller. The upper controller adjusts the upper job execution module according to instruction N4 to complete the corresponding job.

[0096] 2. Driving operations (i.e. completing various vehicle operations under driving conditions such as general sweeping, strong sweeping, watering, dust suppression, etc.).

[0097] 1. The pedal signal sensor transmits the current pedal signal to the engine ECU, and the vehicle speed sensor transmits the current vehicle speed and target speed signal (vehicle speed > 0 signal) to the engine ECU. The engine ECU calculates the engine power P4 (current vehicle speed corresponds to the required power) and P5 (target vehicle speed corresponds to the required power) required for the current pedal depth, current vehicle speed, and target speed, and inputs the values ​​P4 and P5 to the system master controller.

[0098] 2. The upper body operation signal sensor transmits a specific upper body operation signal to the system master controller, and the system master controller calculates the engine power P6 required for this specific operation.

[0099] 3. The system master controller takes into account system losses and performs weighted calculation on the sum of P4 and P6 to obtain P7, and performs weighted calculation on the sum of P5 and P6 to obtain P8.

[0100] (1) First, P7 and P8 are compared with the upper power limit Pmax of the system. If Pmax is exceeded, the control system will feedback a warning message and the operation function will not be executed.

[0101] (2) Next, compare P8 with the controller module database (a cumulative measured database obtained according to internal control standards during vehicle development testing). If P8 is in the database, the appropriate speed R corresponding to P8 is selected. If P8 is not in the database, the two nearest power points are selected with P8 as the base point, and the corresponding appropriate speed R is calculated according to the curve fitting of the measured database in this interval.

[0102] (3) Finally, the output torques N5 and N6 are calculated based on the speed R and the corresponding P5 and P6.

[0103] 4. The system's main controller sends commands N5 and N6 to the engine ECU, which then calculates and sends them to the engine. Following command N5, the engine coordinates with the chassis module to achieve the required driving torque and, in turn, the desired driving speed. Following command N6, the engine provides the required torque to the generator module through the full-power power take-off. The generator module converts mechanical kinetic energy into electrical energy and stores it.

[0104] 5. The system master controller sends the N6 instruction to the generator controller. The generator controller adjusts the generator module according to the N6 instruction and feeds back the N6 instruction to the generator controller after completing the N6 instruction. The generator controller then feeds back to the system master controller that the power energy is ready.

[0105] 6. After the system master controller has prepared its energy, it sends instruction N7 to the upper installation controller. The upper installation controller adjusts the upper installation operation execution module according to instruction N7 to complete the corresponding operation.

[0106] 7. Repeat the process to complete various operations under driving status.

[0107] The present invention can identify, judge and implement various types of superimposed complex working conditions; it solves the problem that the traditional functions used by modification plants all work actions are implemented at a constant engine speed, and effectively improves the working efficiency, noise and comprehensive fuel consumption level; it can dynamically match the corresponding speed and torque according to the power required for complex working conditions, so as to achieve higher efficiency and more fuel-saving effects; when there is an erroneous operation or abnormal working condition, the present invention can identify and give a reminder, and at the same time not execute it to play a corresponding protective role; the present invention can also be expanded to other models.
