Technical Field

[0001] This application relates to the field of engine starting technology, and more specifically, to an engine starting control method, device, equipment, and storage medium. Background Technology

[0002] When the ambient temperature is low, the intake air temperature needs to be preheated to improve the engine starting success rate and avoid engine flooding.

[0003] The existing intake air heating process is controlled separately from the start-up process. It first locks in the intake air and coolant temperatures as a reference temperature, and then determines the heating duration based on this reference temperature. This heating method is susceptible to problems if the intake air heating circuit has a problem, such as an open circuit in the heating grille, which could lead to ineffective heating. Furthermore, the intake air heating process relies solely on heating time, ignoring the influence of factors like grille power on the heating effect, which can easily result in insufficient or excessive heating. Moreover, if the engine is not started for a period after heating, the intake air temperature will cool down, rendering the intake air heating ineffective when the engine starts.

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein.

[0019] This application provides an engine starting control method that dynamically determines the timing of heating and starting by real-time monitoring of intake air temperature and temperature rise rate, thereby improving the starting success rate in low-temperature environments while avoiding energy waste and equipment damage.

[0020] Figure 3 This is a schematic diagram of an engine starting control system according to an embodiment of this application. Figure 3 As shown, in one embodiment, the system consists of an intake air temperature sensor, an ECU, an intake air heating relay, a starter relay, an intake air heating device, and a starter motor.

[0021] The intake air temperature sensor monitors the intake air temperature signal in real time and sends it to the ECU. The ECU performs logical judgments and controls the opening and closing of the intake air heating relay and the starter relay. When the intake air heating relay is closed, the intake air heating device works to heat the intake air. When the intake air heating relay is open, the intake air heating device stops working. When the starter relay is closed, the starter motor turns, starting the engine.

[0022] The engine starting control method of this application embodiment will be described in detail below with reference to the accompanying drawings. Figure 1 As shown, the method mainly includes the following steps: After receiving the start signal, the S101 electronic control unit obtains the real-time monitored intake air temperature.

[0023] In this embodiment, intake air heating control and engine start control are integrated into the electronic control unit, which performs linkage control.

[0024] In one implementation, after receiving the start signal, the electronic control unit acquires the real-time monitored intake air temperature.

[0025] Specifically, the electronic control unit is connected to the intake air temperature sensor. After receiving the start signal, the electronic control unit acquires the intake air temperature collected by the intake air temperature sensor.

[0026] In automotive electronic control systems, the electronic control unit (ECU) monitors the intake air temperature in real time by connecting to an intake air temperature sensor. When the ECU receives a start signal (such as a T50 signal), it immediately activates the communication link with the intake air temperature sensor to obtain the current intake air temperature data collected by the sensor.

[0027] S102 determines whether the intake air temperature is lower than the preset first temperature threshold.

[0028] During engine starting, the electronic control unit (ECU) monitors the intake air temperature data collected by the intake air temperature sensor in real time. When the ECU receives the start signal, it compares the current intake air temperature with a preset first temperature threshold. If the intake air temperature is lower than this preset first temperature threshold, the ECU determines that the engine is in a low-temperature start state and executes the corresponding low-temperature start control strategy based on this determination.

[0029] In one exemplary scenario, the first temperature threshold is 0°C, used to determine whether the intake air temperature is below 0°C. This application does not limit the specific value of the first temperature threshold; it can be set according to actual conditions.

[0030] When the intake air temperature is lower than the first temperature threshold, S103 controls the intake air heating relay to engage and perform intake air heating.

[0031] When the electronic control unit (ECU) detects that the intake air temperature is lower than a preset first temperature threshold, the ECU sends a command to activate the intake air heating relay. Once activated, current flows through the heating circuit, activating the intake air heating device to heat the intake air. This process effectively increases the intake air temperature, improving engine starting performance and operating efficiency in low-temperature conditions, while also helping to reduce fuel consumption and emissions during cold starts.

[0032] In one embodiment, when the intake air temperature is less than a first temperature threshold, the intake air heating relay is activated to heat the intake air. After that, the intake air temperature rise rate is monitored to determine whether the heating process is normal.

[0033] Specifically, the rate of temperature rise of the intake air per unit time is calculated; it is determined whether the rate of temperature rise is less than or equal to the preset temperature rise threshold; if the rate of temperature rise is less than or equal to the temperature rise threshold, an intake air heating abnormality is identified.

[0034] During intake air heating, the electronic control unit (ECU) continuously monitors the temperature data collected by the intake air temperature sensor and calculates the rate of temperature rise per unit time. Specifically, the ECU collects intake air temperature values ​​at two consecutive time points, calculates the difference between these two values, and then divides it by the time interval between the two time points to obtain the rate of temperature rise per unit time. The ECU then compares the calculated rate of temperature rise with a preset temperature rise threshold. If the rate of temperature rise is less than or equal to the preset temperature rise threshold, the ECU determines that there is an abnormality in the intake air heating system.

[0035] In the event of an abnormal intake air heating condition, the intake air heating relay is disconnected, and the electronic control unit (ECU) sends a heating malfunction warning message. Once an intake air heating malfunction is detected, such as a temperature rise rate below a preset threshold, the ECU immediately takes action, disconnecting the intake air heating relay to cut off the heating circuit and prevent relay burnout that could result from continuous heating due to a circuit fault. Simultaneously, the ECU sends a heating malfunction warning message to the vehicle's diagnostic system, notifying the driver or maintenance personnel to inspect and repair the vehicle. This timely fault detection and response mechanism ensures the safe operation of the vehicle and avoids further damage that could be caused by a heating system malfunction.

[0036] In one embodiment, the method further includes determining that the intake air heating is normal and continuing heating if the temperature rise rate is greater than the temperature rise threshold.

[0037] S104 monitors the intake air temperature in real time. When the intake air temperature meets the preset start-up heating conditions, it controls the intake air heating relay to disconnect and controls the engine to start.

[0038] In one implementation, the intake air temperature is monitored in real time, and when the intake air temperature meets the preset starting heating conditions, the intake air heating relay is disconnected to start the engine.

[0039] In one embodiment of this application, the intake air temperature is monitored in real time to determine whether the intake air temperature is greater than or equal to a preset second temperature threshold, where the second temperature threshold is greater than a first temperature threshold. When the intake air temperature is greater than or equal to the second temperature threshold, it is determined that the preset starting heating condition is met, and the intake air heating relay is controlled to disconnect, thereby controlling the engine to start.

[0040] The intake air temperature threshold is set to hysteresis judgment, including a first temperature threshold and a second temperature threshold. If the second temperature threshold is greater than the first temperature threshold, intake air heating will stop when the intake air temperature is greater than or equal to the second temperature threshold. This increases control accuracy and prevents the relay from momentarily engaging and disengaging when the intake air temperature approaches the limit, thus avoiding damage to the circuit.

[0041] By setting a second temperature threshold higher than the first temperature threshold, a temperature hysteresis loop is created. This means that heating will only restart when the intake air temperature drops below the first temperature threshold, and will only stop when the temperature rises to the second temperature threshold. This hysteresis control reduces frequent relay operation, thereby protecting the circuit and improving control stability.

[0042] By preventing the intake air temperature from frequently approaching the set limit, the instantaneous engagement and disengagement of the relays are reduced, thereby lowering the risk of circuit damage. This hysteresis control method not only improves the control accuracy of the intake air heating system but also helps extend the service life of related electrical components, ensuring the reliability and durability of the system.

[0043] In an optional embodiment of this application, the specific values ​​of the second temperature threshold and the first temperature threshold can be preset according to actual conditions, and this application embodiment does not impose any restrictions. For example, the first temperature threshold is 0° and the second temperature threshold is 8°.

[0044] In another optional embodiment of this application, the first temperature threshold and the second temperature threshold are dynamically adjusted based on the ambient temperature.

[0045] Specifically, the electronic control unit acquires the ambient temperature collected by the preset ambient temperature sensor, queries the preset temperature mapping table based on the ambient temperature, and obtains the first temperature threshold and the second temperature threshold corresponding to the ambient temperature; the temperature mapping table stores the mapping relationship between the ambient temperature and the first temperature threshold and the second temperature threshold; the first temperature threshold and the second temperature threshold are dynamically adjusted based on the query results.

[0046] In one exemplary embodiment, a temperature mapping table is created to store the optimal T1 and T2 for different ambient temperature ranges. This table can be developed based on a large amount of experimental data and experience.

[0047]

[0048] By dynamically adjusting the temperature threshold based on environmental parameters, global adaptability is increased, allowing the vehicle to operate normally in cold regions or mild winters without parameter modifications. In less cold environments, unnecessary deep heating is avoided, saving battery power and fuel. Preheating time is minimized while ensuring reliable starting.

[0049] In one embodiment, after the intake air heating relay is disconnected, the method further includes: the electronic control unit determining whether the engine meets the starting conditions; if the engine meets the starting conditions, controlling the starter relay to engage, and the engine starting.

[0050] Understandably, after the intake air heater relay disconnects, the ECU will further determine whether the engine meets the starting conditions. This may include checking the following conditions: Check if the ignition switch is in the start position, if the transmission is in neutral (for manual transmissions) or park (for automatic transmissions), if the clutch pedal is depressed (for manual transmissions), if the brake pedal is depressed (for automatic transmissions), and if the engine speed is below the starting speed threshold.

[0051] If the ECU determines that the engine meets the starting conditions, it will control the starter relay to engage, connecting the starter circuit and causing the starter motor to rotate, thus starting the engine. Under the drive of the starter motor, the engine completes the starting process, transitioning from a stationary state to a running state.

[0052] The advantages of this integrated control method include: Improve starting reliability: By checking the starting condition immediately after intake air heating, the engine can be ensured to start at the optimal temperature and operating conditions, thus improving starting reliability and success rate.

[0053] Optimize starting performance: Starting the engine when the intake air temperature is suitable can improve the engine's starting performance, reduce wear, and extend engine life.

[0054] Simplified control logic: Integrating intake air heating and engine start control together can simplify the ECU's control logic and improve the system's integration and reliability.

[0055] In summary, this implementation optimizes and protects the engine starting process by immediately checking and controlling engine starting after intake air heating, thereby improving vehicle starting performance and reliability. To facilitate understanding of the engine starting control method of the embodiments of this application, the following is in conjunction with the accompanying drawings. Figure 2 Further description.

[0056] like Figure 2 As shown, firstly, the electronic control unit receives the T50 signal and determines whether the intake air temperature is lower than the temperature threshold T1. If it is lower than the temperature threshold T1, it controls the intake air heating relay to engage and begin intake air heating. If it is not lower than the temperature threshold T1, no heating is required, and it determines whether the starting conditions are met, or if there are no starting prohibition conditions. If the starting conditions are met, it controls the starting relay to engage, and the engine starts.

[0057] During intake air heating, the temperature rise ΔT per unit time (Δt) is continuously monitored to ensure it is less than or equal to the threshold T0. If ΔT ≤ the temperature rise threshold T0, an intake air heating malfunction is reported, and the intake air heating relay is disconnected.

[0058] If ΔT > T0, heating continues, and the intake air temperature is continuously monitored to determine if it exceeds the temperature threshold T2. If it exceeds or equals the temperature threshold T2, the intake air heating relay is disconnected to stop heating. The starting conditions are then checked, and if no starting prohibition conditions are met, the starting relay is activated to start the engine.

[0059] The proposed solution directly uses the intake air temperature as the judgment condition, avoiding repeated heating. It monitors the intake air temperature in real time to determine the status and control whether to continue heating. Compared to the method of determining the heating duration by latching a reference temperature at the moment the T15 is powered on, this overcomes the problem of insufficient or overheating caused by factors such as inconsistent heating grille power, resulting in more precise control.

[0060] The proposed solution monitors the intake air heating process to ensure it is functioning correctly. If any abnormality is detected, the process immediately stops and prompts for troubleshooting. This prevents problems in the intake air heating circuit from causing continuous heating and burning out the relay. It also improves the start-up success rate in low-temperature environments while avoiding energy waste and equipment damage.

The first control module 403 is used to control the intake air heating relay to engage and perform intake air heating when the intake air temperature is lower than the first temperature threshold. The second control module 404 is used to monitor the intake air temperature in real time. When the intake air temperature meets the preset start-up heating conditions, it controls the intake air heating relay to disconnect and controls the engine to start.
