Description

Technical Field

[0001] The present application relates to the technical field of vehicle control, and particularly relates to a control method, device, equipment and program product for a range extender. Background Art

[0002] With the application and popularization of new energy fuel engines such as methanol in the automotive industry, the number of faults of new energy fuel engines in the market has increased synchronously; especially for range-extended vehicles, the operating state of the engine as a range extender is decoupled from the overall operating state of the vehicle. For vehicles using new energy fuels with a relatively high water content such as methanol, in scenarios where users drive the vehicle for a short distance, there will be a situation where the range extender starts only during the vehicle's operation but the user has already parked. At this time, the range extender shuts down before completing warm-up, and the overall temperature of the range extender is relatively low. If the user drives the vehicle again within a short period of time, it will cause the range extender to start and stop frequently. Frequent start and stop of the range extender at a relatively low temperature will increase the risk of engine oil emulsification, and thus cause damage to the range extender.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts belong to the scope of protection of the present application.

[0021] Exemplary method

[0022] In view of the problem that the frequent start and stop of the range extender in a range-extended vehicle leads to a relatively high risk of engine oil emulsification, the present application provides a control method for the range extender. This method can be implemented by means of a software algorithm to dynamically adjust the start and stop states of the range extender, thereby reducing the risk of engine oil emulsification. The software algorithm for implementing this method can run on any device with data processing capabilities. For example, the controller already configured in the range-extended vehicle, a remote server capable of data interaction with the range-extended vehicle, etc. The protection scope of the present application is not limited by the type of device on which the software algorithm runs when implementing this method.

[0023] In one embodiment, as Figure 1 shown, the process steps implemented by the range extender control method include:

[0024] Step 101, obtain the warm-up state of the range extender in the vehicle.

[0025] In this embodiment, the vehicle is a range-extended vehicle equipped with a range extender and range-extended supporting hardware. The range-extended vehicle is mainly driven by an electric motor. The range extender is essentially a small and efficient engine dedicated to generating electricity to provide electrical energy for the drive motor. The range extender does not directly participate in vehicle driving, and there is no direct mechanical connection between the range extender and the wheels. The range extender only serves as an energy supplement device, that is, the operation of the range extender is decoupled from the operation of the vehicle.

[0026] In this embodiment, when the vehicle range extender starts, if the range extender is in a cold state (i.e., below its normal operating temperature), it needs to go through a warm-up process. The main purpose of this process is to let the range extender reach its optimal operating temperature as soon as possible, so as to ensure good lubrication effect and efficient performance. For the warm-up process, when the range extender starts running, the thermostat will remain closed to prevent the antifreeze from flowing through the radiator, which can reduce heat dissipation and help the range extender warm up quickly; as the range extender starts to operate, the oil pump delivers oil to each friction surface for lubrication. During this process, the oil will also be gradually heated, reducing viscosity and improving lubrication efficiency. To ensure reasonable operating conditions of the range extender, there is usually a warm-up power limit strategy after the engine starts. When the engine antifreeze temperature is greater than a certain value, the warm-up strategy is exited and the engine can emit maximum power. Therefore, what state the warm-up process is in is directly related to the overall temperature of the range extender (including the temperature of the engine oil). Optionally, the warm-up state includes any one or several of the in-warm-up state, non-warm-up state, and warm-up completed state. This method obtains the warm-up state of the range extender and dynamically adjusts the start and stop of the range extender based on the warm-up state, thereby avoiding too low engine oil temperature and increasing the risk of engine oil emulsification.

[0027] Step 102, update the shutdown frequency value of the range extender based on the warm-up state, where the shutdown frequency value is a value representing the shutdown frequency of the range extender.

[0028] In this application, when the engine oil temperature in the vehicle is too low, the more frequently the range extender starts and stops, the higher the risk of engine oil emulsification. Therefore, the frequency of the range extender's shutdown under different warm-up states can be monitored. Specifically, the frequency of shutdown is numerically characterized by a shutdown frequency value. The larger the shutdown frequency value, the higher the frequency of the range extender's shutdown and the higher the risk of engine oil emulsification. Optionally, the shutdown frequency value can be the cumulative number of times the range extender shuts down or starts within a period of time or under certain conditions; or, the shutdown frequency value can be the average value of the number of times the range extender shuts down or starts per unit time (such as 1 hour) within a period of time or under certain conditions, as long as the shutdown frequency value can characterize the frequency of the range extender's shutdown.

[0029] Step 103: Generate a start control signal for the range extender based on the shutdown frequency value, where the start control signal is used to control the start or stop of the range extender.

[0030] In this embodiment, based on the shutdown frequency value that is continuously updated in real time according to the warm-up state, the high or low risk of engine oil emulsification can be identified in real time. Then, a start control signal is generated based on this shutdown frequency value, and the start or stop of the range extender is flexibly regulated through this start control signal. When the risk of engine oil emulsification is relatively high, the frequent start and stop of the range extender are avoided. At the same time, when the risk of engine oil emulsification is relatively low, the range extender can still operate normally, improving the safety of the vehicle.

[0031] In one embodiment, generating a start control signal for the range extender based on the shutdown frequency value includes: if the shutdown frequency value is less than the degree threshold, generate a first control signal for controlling the range extender to start; if the shutdown frequency value is greater than or equal to the degree threshold, generate a second control signal for controlling the range extender to stop.

[0032] In this embodiment, the start control signal of the range extender is generated through the continuously updated shutdown frequency value. When the shutdown frequency value reaches the degree threshold, it indicates that the shutdown frequency of the range extender has reached a relatively high level, and then a second control signal for controlling the range extender to stop is generated to control the range extender to stop through the second control signal, avoiding the relatively high risk of engine oil emulsification caused by the frequent start and stop of the range extender. When the shutdown frequency value is less than the degree threshold, it indicates that the shutdown frequency of the range extender is relatively low, and then a first control signal for controlling the range extender to start can be allowed to be generated in the state where the shutdown frequency value is less than the degree threshold, so as to control the range extender to start through the first control signal and enable the range extender to start and operate normally to achieve the range extension function.

[0033] In this embodiment, the data type of the shutdown frequency value matches that of the degree threshold. For example, if the shutdown frequency value is the cumulative number of times, the degree threshold is correspondingly configured as the number threshold; if the shutdown frequency value is the average value of the shutdown times, the degree threshold is correspondingly configured as the average value threshold. The specific value of the degree threshold is set based on the actual performance and specific requirements of the range extender, and the protection scope of this application is not limited by the specific value of the degree threshold.

[0034] In one embodiment, based on the warm-up state, the shutdown frequency value of the range extender is updated, including: if the warm-up state is the in-warm-up state, the shutdown frequency value of the range extender is updated based on the antifreeze temperature corresponding to the range extender.

[0035] In this embodiment, when the range extender is in the in-warm-up state, the antifreeze absorbs and transfers heat through the vehicle's circulation system, enabling all parts of the range extender to be evenly heated, thereby accelerating the warm-up process. Therefore, the antifreeze temperature refers to the real-time temperature of the antifreeze, which can be measured by any means such as a temperature sensor. The antifreeze temperature can more accurately reflect the overall temperature of the range extender and also includes the temperature of the engine oil. When the antifreeze temperature is in different temperature ranges, different methods are used to update the shutdown frequency value of the range extender, which can make the shutdown frequency value more accurately reflect the risk degree of engine oil emulsification.

[0036] In one embodiment, the shutdown frequency value includes the cumulative number of shutdowns of the range extender. Updating the shutdown frequency value of the range extender based on the antifreeze temperature corresponding to the range extender includes: if the antifreeze temperature is less than the temperature threshold, when the range extender shuts down, the cumulative number of shutdowns of the range extender is incremented by one.

[0037] In this embodiment, when the range extender is in the in-warm-up state, if the antifreeze temperature is less than the temperature threshold, it indicates that the overall temperature of the range extender is in a relatively low state, and at the same time, the engine oil temperature is also in a relatively low state, and the risk of engine oil emulsification is relatively high. In this state, each time the range extender shuts down, the cumulative number of shutdowns of the range extender is incremented by one, and the cumulative number of shutdowns of the range extender is used to specifically represent the shutdown frequency. The larger the cumulative number of shutdowns of the range extender, the higher the shutdown frequency. At the same time, when the range extender is in the in-warm-up state, power limitation is imposed on the range extender to reduce the risk of range extender damage.

[0038] Generate the start control signal of the range extender based on the continuously updated cumulative number of times the range extender stops. When the cumulative number of times the range extender stops reaches the number threshold, it indicates that the frequency of the range extender's stops has reached a relatively high level. Then generate the second control signal to control the range extender to be stationary, so as to control the range extender to be stationary through the second control signal and avoid the relatively high risk of engine oil emulsification caused by the frequent start and stop of the range extender. When the cumulative number of times the range extender stops is less than the number threshold, it indicates that the frequency of the range extender's stops is relatively low. Then, in the state where the cumulative number of times the range extender stops is less than the number threshold, it is allowed to generate the first control signal to control the range extender to start, so as to control the range extender to start through the first control signal and enable the range extender to start normally and realize the range extension function.

[0039] In this embodiment, the temperature threshold is a threshold set according to the actual situation and needs. For example, the temperature threshold can be set to 60°C; the specific value of the number threshold is set based on the actual performance and specific requirements of the range extender. For example, the number threshold is set to 120 times. The protection scope of this application is not limited by the specific values of the temperature threshold and the number threshold.

[0040] In one embodiment, if the antifreeze temperature is greater than or equal to the temperature threshold, control the range extender to switch from the warm-up state to the non-warm-up state.

[0041] In this embodiment, when the range extender is in the warm-up state, if the antifreeze temperature is greater than or equal to the temperature threshold, it indicates that the overall temperature of the range extender is in a relatively high state and the warm-up process can already end. Then control the range extender to switch from the warm-up state to the non-warm-up state, and the range extender can operate normally to start the engine, and the power generation power of the range extender is no longer limited. Avoid the problem of excessive temperature caused by over-warming and improve the safety of the range extender and the vehicle.

[0042] In one embodiment, based on the warm-up state, update the value of the frequency of the range extender's stops, including: if the warm-up state is the non-warm-up state, update the value of the frequency of the range extender's stops based on the continuous operation duration of the range extender.

[0043] In this embodiment, when the range extender is in the un-warmed-up state, it means that the range extender has not started the warm-up process or the warm-up process has ended. The overall vehicle control can, according to the actual situation and needs, control the range extender to start the warm-up process or keep the warm-up process from starting again. At the same time, in order to ensure more accurate monitoring of the risk of engine oil emulsification in the un-warmed-up state, the continuous operation duration of the range extender can be counted. The continuous operation duration refers to the cumulative duration of the continuous operation of the range extender. When the range extender operates continuously, the high-temperature environment inside the range extender will cause the engine oil temperature to rise. The longer the continuous operation duration of the range extender, the higher the engine oil temperature; the shorter the continuous operation duration of the range extender, the lower the engine oil temperature. In the case where the range extender is in the un-warmed-up state, the engine oil temperature situation can be characterized by counting the continuous operation duration of the range extender. When the continuous operation duration of the range extender is in different duration ranges, different methods are used to update the shutdown frequency value, so that the shutdown frequency value can more accurately characterize the shutdown frequency of the range extender and improve the accuracy of range extender control.

[0044] It should be noted that the shutdown frequency value in the un-warmed-up state can be a value counted from zero when the range extender has not started the warm-up process; if the range extender has started the warm-up process, the shutdown frequency value can continue to be counted based on the antifreeze temperature in the warm-up state. The shutdown frequency value in the un-warmed-up state can also be a value updated based on the continuous operation duration on the basis of the value already counted when the range extender is in the warm-up state. Thus, full-time monitoring of the range extender is realized, the comprehensiveness of monitoring is improved, and the risk of engine oil emulsification is further reduced.

[0045] In one embodiment, the shutdown frequency value includes the cumulative number of shutdowns of the range extender. Updating the shutdown frequency value of the range extender based on the continuous operation duration of the range extender includes: if the continuous operation duration is less than the duration threshold, when the range extender shuts down, increment the cumulative number of shutdowns of the range extender by one; if the continuous operation duration is greater than or equal to the duration threshold, reset the cumulative number of shutdowns of the range extender to zero.

[0046] In this embodiment, when updating the shutdown frequency value based on the continuous operation duration of the range extender, if the continuous operation duration is less than the duration threshold, it indicates that the continuous operation duration of the range extender is short, and the heat provided by the continuous operation of the range extender has not raised the engine oil temperature to a level that can avoid engine oil emulsification. Then, when the range extender shuts down, increment the cumulative number of shutdowns of the range extender by one, and continue to monitor the shutdown frequency of the range extender through the cumulative number of shutdowns of the range extender. If the continuous operation duration is greater than or equal to the duration threshold, it indicates that the continuous operation duration of the range extender is long, and the heat provided by the continuous operation of the range extender has raised the engine oil temperature to a level that can avoid engine oil emulsification. Then, reset the cumulative number of shutdowns of the range extender to zero, so as to monitor the shutdown frequency through the cumulative number of shutdowns of the range extender when the engine oil temperature drops again.

[0047] In this embodiment, the start control signal of the range extender is generated based on the continuously updated cumulative number of times the range extender stops. When the cumulative number of times the range extender stops reaches the number threshold, it indicates that the frequency of the range extender stopping has reached a relatively high level. Then, a second control signal for controlling the range extender to be stationary is generated to control the range extender to be stationary through the second control signal, so as to avoid the relatively high risk of engine oil emulsification caused by the frequent start and stop of the range extender. When the cumulative number of times the range extender stops is less than the number threshold, it indicates that the frequency of the range extender stopping is relatively low. Then, in the state where the cumulative number of times the range extender stops is less than the number threshold, the first control signal for controlling the range extender to start is allowed to be generated to control the range extender to start through the first control signal, so that the range extender can start normally and realize the range extension function. Of course, after clearing the cumulative number of times the range extender stops, it also belongs to the state where the cumulative number of times the range extender stops is less than the number threshold, thereby ensuring that the range extender can start normally and realize the range extension function. The specific value of the number threshold is set based on the actual performance and specific requirements of the range extender. For example, the number threshold is set to 120 times. The protection scope of this application is not limited by the specific value of the number threshold.

[0048] In one embodiment, when generating the start control signal of the range extender, it further includes: generating a prompt message based on the frequency of stopping value. Specifically, if the frequency of stopping value is less than the degree threshold, while generating the first control signal for controlling the range extender to start, a prompt message indicating that warm start and pure electric mode are unavailable is generated; if the frequency of stopping value is greater than or equal to the degree threshold, while generating the second control signal for controlling the range extender to be stationary, a prompt message indicating that warm start is not required and pure electric mode is available is generated.

[0049] In a specific embodiment, as Figure 2 shown, taking the generator control unit (GCU) of the range extender as the execution subject as an example, the process of specifically implementing the range extender control method includes:

[0050] Step 201, the vehicle is powered on, and the cumulative number of times the range extender stops is initially zero;

[0051] Step 202, obtain the warm-up state of the range extender. If the warm-up state is the warm-up in progress state, execute Step 203; if the warm-up state is the not warmed-up state, execute Step 207;

[0052] Step 203, obtain the antifreeze temperature corresponding to the range extender;

[0053] Step 204, determine whether the antifreeze temperature is less than the temperature threshold. If so, execute Step 205; if not, execute Step 206;

[0054] Step 205, when the range extender stops, increment the cumulative number of range extender stops by one, and execute Step 211;

[0055] Step 206, control the range extender to switch from the warm-up state to the non-warm-up state;

[0056] Step 207, obtain the continuous operation duration of the range extender;

[0057] Step 208, determine whether the continuous operation duration is less than the duration threshold. If so, execute Step 209; if not, execute Step 210;

[0058] Step 209, when the range extender stops, increment the cumulative number of range extender stops by one, and execute Step 211;

[0059] Step 210, clear the cumulative number of range extender stops, and execute Step 202 until the vehicle is powered off;

[0060] Step 211, determine whether the cumulative number of range extender stops is less than the number threshold. If so, execute Step 212; if not, execute Step 213;

[0061] Step 212, generate a first control signal to control the start of the range extender, that is, the engine send request signal is 1, and execute Step 202 until the vehicle is powered off;

[0062] At this time, the second control signal is to initiate a start request. At the same time, send an oil anti-emulsification function activation flag activation signal to the vehicle controller, and the range extender can start and run normally;

[0063] Step 213, generate a second control signal to control the range extender to be stationary, that is, the engine send request signal is 0, and execute Step 202 until the vehicle is powered off;

[0064] At this time, the second control signal is not to initiate a start request. At the same time, send an oil anti-emulsification function activation flag non-activation signal to the vehicle controller. The vehicle controller sends prompt information such as pop-ups and text to the vehicle's gateway and instrument, and the instrument displays the prompt information. For example, the instrument displays "Start for warm-up and lubrication, pure electric mode is unavailable". At this time, the vehicle cannot enter the pure electric mode, and the range extender is forced to start until the GCU send request signal is 0.

[0065] In this application, obtain the warm-up state of the range extender in the vehicle; based on the warm-up state, update the value of the shutdown frequency of the range extender, where the shutdown frequency value is a value representing the shutdown frequency of the range extender; based on the shutdown frequency value, generate a start control signal for the range extender, where the start control signal is used to control the start or stop of the range extender. In the above process, the warm-up state of the range extender directly affects the overall temperature of the range extender. Therefore, based on the warm-up state of the range extender, count the shutdown frequency value of the range extender, and control whether the range extender starts based on the frequency, so as to avoid the problem of high risk of oil emulsification caused by frequent start-stop when the range extender has not completed warm-up and the temperature is low, reduce the possibility of damage to the range extender, and improve the safety of the vehicle.

[0066] Furthermore, dynamically monitor the operation of the range extender. When it is detected that the user frequently starts and stops the range extender in a low-temperature situation, remind the user to warm up the range extender by means of prompt messages, etc., to prevent the problem of oil emulsification of the range extender caused by frequent start-stop of the range extender, and further improve the safety of the range extender and the vehicle.
