[0035] During vehicle operation, when the engine controller experiences an abnormal power outage and is subsequently powered back on, it acquires the vehicle's attitude and status information. The vehicle status information includes at least one of the vehicle's speed and engine speed. Based on the vehicle's attitude information, it determines the type of road the vehicle is currently traveling on, which can be categorized as downhill or non-downhill. If the vehicle is on a downhill road, controlling the engine's automatic fuel injection and ignition could lead to an accident, posing a safety hazard to the vehicle and its occupants. Therefore, before determining whether to control engine fuel injection and ignition, the type of road the vehicle is on must be determined. Engine fuel injection and ignition can only be controlled when the vehicle is on a non-downhill road to ensure the safety of the vehicle and its occupants. When the vehicle is on a non-downhill road, indicating a safe road, if the vehicle's status information meets preset conditions, engine fuel injection and ignition are controlled to restart the engine, allowing the vehicle to continue driving. This improves the stability of the vehicle's operation and eliminates the need for manual ignition, enhancing the user experience.

[0036] It is understood that the beneficial effects of the second to fourth aspects mentioned above can be found in the relevant descriptions in the first aspect mentioned above, and will not be repeated here. Attached Figure Description

[0050] During vehicle operation, abnormalities may occur. For example, poor contact in the vehicle's wiring harness may cause the engine controller to lose power abnormally, resulting in the engine stopping fuel injection and ignition. In this case, the user needs to manually control the engine to restart fuel injection and ignition, which affects the smoothness of vehicle operation, increases the user's workload, and reduces the user experience.

[0051] To address the aforementioned problems, this application provides an engine control method applied to an engine controller. See also... Figure 1 As shown, the engine control method includes steps S101 to S103.

[0052] Step S101: When the engine controller is powered on again due to an abnormal power outage, the vehicle's attitude information and vehicle status information are acquired. The vehicle status information includes at least one of the vehicle's driving speed and the engine's rotational speed.

[0053] Specifically, during vehicle operation, an abnormality may occur that causes the engine controller to lose power. Within a very short time, the engine controller will regain power. After the engine controller regains power due to an abnormal power outage, it can resume its communication capabilities. At this time, the engine controller can communicate with other controllers or sensors on the vehicle to obtain information such as the vehicle's speed, attitude, and engine speed.

[0054] For example, the engine controller can obtain the engine speed through a sensor on the vehicle used to detect the engine speed. The engine controller can obtain the vehicle speed through a sensor on the vehicle used to detect the vehicle's speed. The engine controller can obtain the vehicle's attitude information through a sensor on the vehicle used to detect the vehicle's attitude information.

[0055] Step S102: Determine the type of road the vehicle is currently traveling on based on the vehicle's attitude information.

[0056] Specifically, the types of roads a vehicle travels on can be divided into downhill roads and non-downhill roads. When a vehicle is on a downhill road, controlling the engine's automatic fuel injection and ignition may lead to an accident, posing a safety hazard to the vehicle and its occupants. Therefore, before determining whether to control engine fuel injection and ignition, it is necessary to determine the type of road the vehicle is on. Engine fuel injection and ignition can only be controlled when the vehicle is on a non-downhill road to ensure the safety of the vehicle and its occupants.

[0057] For example, such as Figure 2 As shown, step S102 may include steps S1021 to S1023.

[0058] Step S1021: Determine the vehicle's pitch angle based on the vehicle's attitude information.

[0059] Specifically, the vehicle is equipped with an Inertial Measurement Unit (IMU) that can detect vehicle attitude information. The IMU can collect the vehicle's attitude information, and the engine controller can obtain the vehicle's attitude information by communicating with the IMU. After receiving the attitude information, the engine controller can determine the vehicle's current pitch angle by analyzing the attitude information.

[0060] Step S1022: When the vehicle's pitch angle is greater than or equal to a preset angle, determine that the type of road the vehicle is currently traveling on is a downhill road.

[0061] Step S1023: When the vehicle's pitch angle is less than the preset angle, determine that the type of road the vehicle is currently traveling on is a non-downhill road.

[0062] Specifically, after determining the vehicle's current pitch angle, it is compared with a preset angle. If the vehicle's pitch angle is greater than or equal to the preset angle, the type of road the vehicle is currently traveling on is determined to be a downhill road. If the vehicle's pitch angle is less than the preset angle, the type of road the vehicle is currently traveling on is determined to be a non-downhill road.

[0063] It should be noted that designers can set the specific value of the preset angle according to actual needs. For example, the preset angle can be set to 30°. The pitch angle of a vehicle going downhill is a positive value, and the pitch angle of a vehicle going downhill is a negative value. Therefore, when the vehicle's pitch angle is greater than or equal to 30°, it is determined that the vehicle is currently on a downhill road; when the vehicle's pitch angle is less than 30°, it is determined that the vehicle is currently on a non-downhill road.

[0064] Step S103: When the type of the road the vehicle is currently traveling on is not a downhill road and the vehicle's status information meets the preset conditions, control the engine to inject fuel and ignite.

[0065] Specifically, when the vehicle is currently traveling on a non-downhill road, it means that controlling the engine's fuel injection and ignition will not pose a safety hazard to the vehicle and its occupants. Therefore, it is necessary to determine whether the vehicle's status information meets the preset conditions. If the vehicle's status information meets the preset conditions, then the engine's fuel injection and ignition are controlled to restart the engine. At the same time, the transmission controller maintains the current forward gear, allowing the vehicle to continue driving. This improves the smoothness of vehicle driving and eliminates the need for manual ignition by the user, enhancing the user experience.

[0066] In some embodiments, such as Figure 3 As shown, the vehicle's status information includes the vehicle's speed, so step S103 may include step S1031.

[0067] Step S1031: When the type of road the vehicle is currently traveling on is not a downhill road and the vehicle's speed is greater than or equal to the preset speed, the anti-theft authentication is maintained in the pass state, and the engine fuel injection and ignition are controlled.

[0068] Specifically, when the vehicle is currently traveling on a non-downhill road, it indicates that the safety of automatic engine injection and ignition is met. When the vehicle speed is greater than or equal to the preset speed, it indicates that the vehicle speed is relatively high and the engine speed is relatively high. When the engine controller experiences an abnormal power outage and is quickly restored, the vehicle's engine speed can maintain a high rotation speed, meeting the requirements for engine injection and ignition. To ensure the engine quickly resumes injection and ignition, the anti-theft authentication is maintained, and engine injection and ignition are controlled without requiring further anti-theft authentication. This allows the engine to quickly inject and ignite, ensuring the vehicle can continue to drive normally and improving vehicle stability. Furthermore, it eliminates the need for the user to manually control engine injection and ignition again, improving the user experience.

[0069] It should be noted that designers can set the specific value of the preset driving speed based on vehicle parameters or through experimentation. For example, the preset driving speed can be set to 15 km / h. When the vehicle speed is greater than or equal to 15 km / h, it indicates that the current vehicle speed is relatively high. At this time, the engine speed is relatively high, and when the engine controller experiences an abnormal power failure and is then restored, the engine speed will still meet the requirements for fuel injection and ignition. If the vehicle speed is less than 15 km / h, it indicates that the vehicle speed is relatively low. When the engine controller experiences an abnormal power failure and is then restored, the engine speed may decrease, resulting in the engine speed not meeting the requirements for fuel injection and ignition.

[0070] In some embodiments, such as Figure 3 As shown, the vehicle status information also includes the engine speed, and step S103 may also include step S1032.

[0071] Step S1032: When the type of road the vehicle is currently traveling on is not a downhill road, the vehicle speed is less than the preset speed, the anti-theft authentication information is received, and the engine speed meets the ignition requirements, control the engine to inject fuel and ignite.

[0072] Specifically, when the vehicle is currently traveling on a non-downhill road, the vehicle's speed is less than the preset speed, the anti-theft authentication information is received, and the engine speed meets the ignition requirements, it indicates that the vehicle's current state is suitable for controlling the engine's automatic fuel injection and ignition. Therefore, controlling the engine's automatic fuel injection and ignition allows the engine to restart, enabling the vehicle to continue driving. This improves the vehicle's driving stability and eliminates the need for manual ignition by the user, enhancing the user experience.

[0073] In some embodiments, such as Figure 4 As shown, step S1032 may specifically include steps S10321 to S10323.

[0074] Step S10321: When the type of road the vehicle is currently traveling on is not a downhill road and the vehicle's speed is less than the preset speed, send anti-theft authentication information.

[0075] Specifically, if a thief pushes the vehicle, raising the engine to ignition point, the engine automatically injects fuel and starts, potentially allowing the thief to successfully steal the vehicle. To prevent this, when the vehicle is traveling on a non-downhill road and at a speed lower than a preset speed, an anti-theft authentication message needs to be sent to the vehicle controller. Furthermore, to improve the speed of engine fuel injection and ignition control, the anti-theft authentication message is sent within a preset time after confirming that the vehicle is traveling on a non-downhill road and at a speed lower than the preset speed.

[0076] Designers can set the first preset time according to actual needs; for example, the first preset time can be set to 50ms.

[0077] Step S10322: After receiving the anti-theft authentication pass information, determine whether the ignition requirements are met based on the engine speed.

[0078] Specifically, after receiving the anti-theft authentication information, the body controller authenticates it. If the authentication is successful, it returns an anti-theft authentication success message. To improve the speed of controlling engine fuel injection and ignition, the body controller needs to complete the authentication process within a second preset time.

[0079] Designers can set the second preset time according to actual needs. For example, the second preset time can be set to 50ms.

[0080] If the vehicle's speed is lower than the preset speed, it indicates that the vehicle is moving too slowly. When the engine controller experiences an abnormal power outage and is subsequently restored, the engine speed may drop to a level insufficient for fuel injection and ignition. Therefore, after receiving the anti-theft authentication pass information (i.e., anti-theft authentication is successful), it is necessary to determine whether the ignition requirements are met based on the engine speed.

[0081] For example, when the engine speed is greater than or equal to a preset speed, it is determined that the engine speed meets the ignition requirements. When the engine speed is less than the preset speed, it is determined that the engine speed does not meet the ignition requirements.

[0082] It should be noted that the preset speed is the minimum engine speed required for fuel injection and ignition. Designers can set the specific value of the preset speed based on the engine's performance parameters. For example, the preset speed can be set to 500 rpm. When the engine speed is greater than or equal to 500 rpm, the engine fuel injection and ignition requirements are met; when the engine speed is less than 500 rpm, the engine fuel injection and ignition requirements are not met.

[0083] Step S10323: When it is determined that the engine speed meets the ignition requirements, control the engine to inject fuel and ignite.

[0084] Specifically, when the engine speed meets the ignition requirements, it means that the engine is ready for fuel injection and ignition. At this time, the engine is controlled to inject fuel and ignite, restarting the engine. Meanwhile, the transmission controller maintains the current forward gear, allowing the vehicle to continue driving. This improves the smoothness of the vehicle's driving and eliminates the need for manual ignition, thus enhancing the user experience.

[0085] In some embodiments, such as Figure 4 As shown, after step S10322, steps S10324 and S10325 may also be included.

[0086] Step S10324: When the engine speed does not meet the ignition requirements, control the engine speed to increase.

[0087] Specifically, if the engine speed does not meet the ignition requirements, the engine controller controls the starter motor to work, using the starter motor to drive the engine and increase the engine speed.

[0088] Step S10325: When the engine speed increases to meet the ignition requirements, control the engine to inject fuel and ignite.

[0089] Specifically, if the engine speed meets the ignition requirements, it means the engine can perform fuel injection and ignition. At this time, the engine controller will control the engine to inject fuel and restart the engine, allowing the vehicle to continue driving normally and improving the smoothness of vehicle operation. At the same time, no manual operation is required from the user, improving the user experience.

[0090] In some embodiments, the engine control method further includes sending a prompt signal when the type of road the vehicle is currently traveling on is a downhill road; wherein the prompt signal is used to instruct the user to manually control the engine fuel injection and ignition.

[0091] Specifically, when a vehicle is on a downhill slope, automatically injecting fuel and igniting the engine could lead to an accident, posing a safety hazard to the vehicle and its occupants. Therefore, when the vehicle is traveling on a downhill slope, a warning signal is sent, and the vehicle's gear is kept in forward gear. This warning signal can be displayed on the vehicle's screen, audio system, or indicator lights. Upon receiving this signal, the user is aware that manual control of the vehicle is necessary. The user can manually control the engine to inject fuel and restart it. This allows the user to maintain focus and prevent accidents, thus improving vehicle safety.

[0092] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.
