Description

Technical Field

[0001] This invention relates to the field of engine control technology, and in particular to an engine power distribution control method, device, vehicle, and storage medium. Background Technology

[0002] When an engine is operating under high load, its power output is usually insufficient to meet the driver's needs. Currently, there are roughly two solutions to increase engine power under high load: one is to increase the amount of fuel injection to compensate for the power increase within a certain period of time, and the other is to increase the amount of air to increase power by identifying whether the engine is in a power-limited state, increasing the intake boost capacity, and controlling the opening of the intake and exhaust throttle valves.

[0003] Current engine power enhancement solutions can only control a single subsystem (such as the fuel system or air system), but cannot coordinate multiple subsystems to complete the power enhancement function, resulting in limited power increase. Furthermore, they cannot differentiate based on engine operating conditions; all situations requiring power enhancement are treated as a "one-size-fits-all" solution. For example, if a driver suddenly floores the accelerator pedal, existing strategies can only increase power for a limited time. If the time is too long, the power will return to the original level or even decrease. Summary of the Invention

[0039] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0040] Figure 1 This invention provides a flowchart of an engine power distribution control method. This embodiment is applicable to situations where the power distribution of various subsystems is coordinated based on the driver's power demand and engine operating conditions. This engine power distribution control method can be executed by an engine power distribution control device, which can be implemented in hardware and / or software and can be configured in a vehicle. Figure 1 As shown, the engine power distribution control method includes:

[0041] S110: Obtain safety protection parameters during engine power enhancement and power limiting parameters when the engine is under high load. Safety protection parameters include cooling system parameters, fuel system parameters, and fault detection parameters. Power limiting parameters include driver torque demand, fuel injection torque, and engine load rate.

[0042] The cooling system is primarily responsible for regulating the engine's operating temperature in a vehicle, preventing damage from overheating. A typical cooling system includes components such as a radiator, water pump, fan, coolant, thermostat, and coolant piping. These components work together to ensure the engine remains within its optimal operating temperature range, thus improving engine performance and efficiency and extending its lifespan. In this embodiment, considering safety during engine power increase, the cooling system parameters can be parameters of its components. These parameters include one or more of the following: water pump temperature, cooling fan temperature, radiator temperature, and engine block temperature. During engine power increase, one or more of these temperatures may rise; therefore, the activation of the cooling system can be determined based on this temperature increase.

[0043] The fuel system is also an indispensable part of the overall vehicle system. It consists of a fuel pump, fuel filter, and fuel injectors, and its main function is to ensure the required fuel flow for the engine under various operating conditions. The operating status of the fuel system directly affects the engine's combustion efficiency and power output; therefore, its performance and stability are crucial to the operation of the entire vehicle. In this embodiment, considering safety protection during engine power increase, the fuel system parameters can be the fuel injection quantity at the current engine speed.

[0044] When a subsystem of the engine (such as the fuel system, intake system, or ignition system) malfunctions, the onboard computer detects these anomalies and automatically adjusts the performance of the relevant subsystem or shuts down some functions to prevent the malfunction from worsening or causing more serious damage to the engine. In this embodiment, considering safety protection during engine power enhancement, the fault detection parameters can include fault information such as a malfunction in the fuel system, intake system, ignition system, or emission system.

[0045] When the engine is under high load, power limiting parameters related to engine control work together in the engine control system to ensure stable and efficient engine operation under high load and to avoid potential damage or performance degradation. In this embodiment, the power limiting parameters under high load may include driver torque demand, fuel injection torque, and engine load rate.

[0046] S120 controls the power distribution of various subsystems in the vehicle system based on cooling system parameters, fuel system parameters, fault detection parameters, driver torque requirements, fuel injection torque, and engine load rate.

[0047] In this embodiment, the cooling system in the vehicle system is controlled to distribute power according to the cooling system parameters. For accessories such as fans, thermostats, and water pumps, if one or more of the water pump temperature, cooling fan temperature, radiator temperature, and engine block temperature exceed a set temperature threshold, the relevant accessories are shut down for a short time, provided that the corresponding temperature does not exceed the limit, thereby reducing the torque consumption of the vehicle accessories and improving the output power of the engine.

[0048] Furthermore, by enabling post-injection and adjusting the advance angle, the turbocharger speed can be quickly increased to improve intake air volume and combustion efficiency. That is, if the fuel injection quantity of the engine at the current speed exceeds the fuel injection quantity corresponding to the external characteristic curve, the fuel system in the whole vehicle system will be controlled to distribute power. At the same time, when the engine is detected to be under long-term high load, it can be coordinated with the timer to increase the fuel injection quantity for a short time while ensuring safety.

[0049] When a serious engine malfunction occurs, controlling the relevant subsystems to degrade to a lower value is a protective measure designed to prevent the activation of faulty functions from impacting engine safety. This degradation strategy is an automatic measure taken by the vehicle's intelligent control system to ensure safe vehicle operation. In this embodiment, when a serious engine malfunction is detected based on fault detection parameters, the relevant subsystems are controlled to degrade to a lower value to prevent the activation of this function from affecting engine safety. Furthermore, when emissions deteriorate due to excessive load, this state is used to promptly activate the aftertreatment management system to ensure proper engine emissions.

[0050] Based on the above, the ECU identifies the power limitations of the engine under high load conditions. Specifically, if the driver's torque demand exceeds a set torque threshold, the fuel injection torque exceeds a set fuel injection threshold, and the engine load rate exceeds a set load rate threshold, the ECU controls the power distribution to various subsystems within the vehicle system. Specifically, a driver torque demand exceeding the set torque threshold usually means the driver desires greater power output and will increase the accelerator pedal opening, indicating a high demand for power. Fuel injection torque refers to the maximum torque the engine's fuel injection system can provide. When the fuel injection torque exceeds the set fuel injection threshold, it indicates the engine is injecting fuel at maximum capacity to meet the high power output demand. Engine load rate refers to the ratio of the actual torque produced at a specific engine speed to the maximum torque the engine can produce. When the engine load rate exceeds the set load rate threshold, it indicates the engine is under significant workload, reflecting a strong demand for power. In summary, when these three conditions are simultaneously met, the vehicle is in a state of high power demand. In this state, the engine and transmission system need to work together to provide sufficient power to meet the driver's driving intentions and the vehicle's operational needs.

[0051] Furthermore, before controlling the power distribution of each subsystem in the vehicle system based on the driver's torque demand, fuel injection torque, and engine load rate, it also includes: obtaining the engine's external characteristic torque, overheat protection limiting torque, fault protection limiting torque, and smoke limiting torque under the current operating conditions.

[0052] Driver torque demand is the torque requirement currently input by the driver through the accelerator pedal, calculated by the engine control unit (ECU) based on the accelerator pedal opening and the current engine speed. External characteristic torque is the engine's external characteristic torque under current operating conditions, i.e., the maximum torque the engine can output at that speed, usually given by performance curves or data sheets provided by the engine manufacturer. Overheat protection limiting torque is the limiting torque set by the engine overheat protection system; when the engine cooling system detects that the engine temperature is too high, the ECU reduces the torque output to a safe value to prevent engine damage. Fault protection limiting torque is the limiting torque set by the engine fault protection system; when the engine control system detects a fault (such as sensor failure, actuator failure, etc.), the ECU limits torque output to protect the engine and prevent further damage. Smoke limiting torque is the limiting torque set by the smoke limiting system, which is usually related to emission control. Under emission control requirements, to prevent excessive engine smoke emissions, the ECU may limit torque output to reduce fuel injection.

[0053] Specifically, if the driver's torque demand is greater than the external characteristic torque, or the driver's torque demand is greater than the overheat protection limit torque, or the driver's torque demand is greater than the fault protection limit torque, or the driver's torque demand is greater than the smoke limit torque, then the engine will be controlled to enter the corresponding external characteristic limit mode, overheat protection limit mode, fault limit mode, or smoke limit mode, and the various subsystems in the vehicle system will distribute power accordingly.

[0054] In other words, the minimum limit torque among the external characteristic torque, overheat protection limit torque, fault protection limit torque, and smoke limit torque is taken as the engine's output torque, and the limiting mode corresponding to the minimum limit torque is taken as the engine's torque limit mode. That is, if the driver's required torque is less than or equal to the external characteristic torque and no other limiting torques are in effect, then the current driving mode is normal; if the overheat protection limit torque is the minimum, then the current driving mode is overheat protection; if the fault protection limit torque is the minimum, then the current driving mode is engine fault protection; if the smoke limit torque is the minimum, then the current driving mode is emission control.

[0055] It's important to note that actual vehicle control systems may employ more complex logic and algorithms to handle these torque limits, including considering combinations and priorities of multiple constraints. Furthermore, different vehicle and engine manufacturers may have different torque limiting strategies and mode definitions. Therefore, specific analysis and design based on the actual situation are necessary for practical applications.

[0056] Based on the above embodiments, when the duration of the engine being under high load exceeds a set time threshold, a downshift request signal is sent to the transmission to control the transmission to change the gear ratio, improve the vehicle's traction, and thus ensure the improvement of the vehicle's power performance.

[0057] The technical solution of this invention acquires safety protection parameters during engine power enhancement and power limiting parameters under high engine load conditions. Safety protection parameters include cooling system parameters, fuel system parameters, and fault detection parameters. Power limiting parameters include driver torque demand, injection torque, and engine load rate. Based on these parameters, the invention controls power distribution among various subsystems within the vehicle system. By calculating the engine power limitation state and its causes through various modules of the ECU, and coordinating the entire engine system for optimized control, this invention can further improve engine output efficiency and avoid problems such as speed drop during hill climbs when power demand suddenly increases or engine output power is continuously limited. Simultaneously, it considers safety protection conditions to ensure engine reliability and emissions.
