Description

Technical Field

[0001] The present invention relates to the field of vehicle control technology, and in particular to a method, device, equipment and medium for controlling an electrically adjustable steering column. Background Art

[0002] The vehicle's electrically adjustable steering column is a torque transmission device that transmits the steering torque applied by the driver on the steering wheel to the steering gear assembly through the steering column to achieve the vehicle's steering function. In addition, the vehicle's electrically adjustable steering column can also be driven by a motor to adjust the extension and angle of the steering wheel, which can be adjusted according to the driver's comfort level to improve driving comfort.

[0003] However, when the ambient temperature is too low, such as below -30℃, the resistance of the lubricating oil and other grease in the various parts of the electric steering column increases, making the probability of the motor successfully driving the electric steering column to move lower, which can easily lead to failure of the electric steering column and affect the user experience.

[0081] The embodiment of the present application solves the technical problem in the prior art that the electric steering column has a high probability of failure when the ambient temperature is too low by providing a method for controlling the electric steering column.

[0082] The technical solution of the embodiment of the present application is to solve the above technical problems, and the overall idea is as follows:

[0083] The embodiment of the present application monitors the ambient temperature of the vehicle when the vehicle is parked; monitors the passenger compartment temperature of the vehicle when the ambient temperature is less than a first ambient preset temperature; and controls the vehicle's electric adjustable steering column to drive the vehicle's steering wheel to a preset driving position when the passenger compartment temperature is less than a first cabin preset temperature. The preset driving position refers to a position that is convenient for the driver to drive the vehicle. It can be seen that the embodiment of the present application analyzes the ambient temperature and the passenger compartment temperature to determine whether it is necessary to control the vehicle's electric adjustable steering column in advance to drive the vehicle's steering wheel to a preset driving position, so as to realize the courtesy function of the electric adjustable steering column while ensuring driving priority. In this way, when the driver needs to use the car, the probability of failure of the electric adjustable steering column in a low temperature environment can be minimized to improve the user experience.

[0084] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0085] First of all, the term "and / or" in this article is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0086] The vehicle's electrically adjustable steering column is a torque transmission device that transmits the steering torque applied by the driver on the steering wheel to the steering gear assembly through the steering column to achieve the vehicle's steering function. In addition, the vehicle's electrically adjustable steering column can also be driven by a motor to adjust the extension and angle of the steering wheel, which can be adjusted according to the driver's comfort level to improve driving comfort.

[0087] For example, when the driver parks the car and prepares to get out, the electrically adjustable steering column can be moved away from the driver's seat, making the driver's seat more spacious and convenient for the driver to get out. When the driver opens the door and prepares to get in, the electrically adjustable steering column can be moved closer to the driver's seat, so that the steering wheel is in a position where the driver can drive normally, making it easier for the driver to control the vehicle.

[0088] However, when the ambient temperature is too low, such as in an environment below -30°C, the grease resistance such as lubricating oil in various parts of the electric adjustable steering column increases, making the probability of the motor successfully driving the electric adjustable steering column to move lower, which can easily cause the electric adjustable steering column to fail and affect the user experience.

[0089] For example, when the ambient temperature is too low, when the driver needs to use the vehicle, the electric steering column cannot be adjusted to the driving position in the low temperature, making it impossible for the driver to drive the vehicle. Or, when the electric steering column stays in the driving position and cannot be adjusted to the avoidance position, it reduces the convenience of the driver getting on and off the vehicle and reduces the customer experience.

[0090] There are two main ways to solve the above problem in the related art. The first way is that when the ambient temperature is too low, the driver needs to turn on the air conditioner to warm up the car and wait for a while before adjusting the electric steering column to the driving position. Usually, the driver needs to warm up the car and wait for about 10 minutes before driving. The second way is that after the driver gets in the car, the electric steering column is adjusted very slowly, and it takes about 15 seconds to reach the driving position.

[0091] It can be seen that both methods provided in the relevant technology have the problem that the probability of failure of the electric adjustment steering column in low temperature environment is relatively high. Therefore, how to reduce the probability of failure of the electric adjustment steering column in low temperature environment is a problem that needs to be solved urgently.

[0092] In order to solve the above problems, the present application provides the following embodiments: Figure 1 An electrically adjustable steering column control system shown includes an electronic control unit, a regional control unit, an electrically adjustable steering column, an outside temperature sensor, an inside temperature sensor, a clock, a power supply, the Internet, a driver's door, and a driver's seat belt.

[0093] Among them, the outside temperature sensor is used to detect the ambient temperature of the vehicle, the inside temperature sensor is used to detect the temperature inside the passenger compartment of the vehicle, the clock is used to provide the current time (or the current moment), the power supply is used to wake up the Internet, and the Internet is used to update the clock and obtain the temperature forecast data of the current location of the vehicle from the network. The driver's door is used to provide a driver's door opening signal to trigger the electric adjustment steering column to move to the preset driving position, and the driver's seat belt is used to provide a driver's seat belt unbuckle signal to trigger the electric adjustment steering column to move to the preset avoidance position.

[0094] The electronic control unit can be a newly added controller on the vehicle or an existing controller of the vehicle, and is used to obtain data corresponding to the outside temperature sensor, the inside temperature sensor, the clock, the power supply, the Internet, the driver's door, and the driver's seat belt, and to rely on these data to execute an electric adjustment steering column control method provided later in the embodiment of the present application. The regional control unit is the control unit corresponding to the electric adjustment steering column in the vehicle.

[0095] The following is a description of an electrically adjustable steering column control method provided in an embodiment of the present application.

[0096] The control method provided in the embodiment of the present application is mainly used in the parking state of the vehicle, that is, the embodiment of the present application can only be used when the vehicle is stationary, the engine is turned off, or other non-moving states to control the electric adjustable steering column to ensure driving safety and control safety of the electric adjustable steering column.

[0097] In addition, the control method provided in the embodiment of the present application is mainly used in scenes with lower temperatures. For example, the start condition of the electric steering column control method can be preset, and the subsequent electric steering column control method will be executed only when the start condition is met. The start condition can be that the ambient temperature is below zero (such as -10°C), and the start condition can also be the duration of the winter in the local area where the vehicle is located, such as the winter in a certain place is from November 1st to April 30th.

[0098] After the start-up conditions are met, an electric steering column control method provided in the embodiment of the present application can be executed. Figure 2 , the method includes steps S21 to S23.

[0099] Step S21, monitoring the ambient temperature of the vehicle;

[0100] Step S22, monitoring the passenger compartment temperature of the vehicle when the ambient temperature is less than a first ambient preset temperature;

[0101] Step S23, when the temperature of the passenger compartment is lower than the preset temperature in the first compartment, control the vehicle's electrically adjustable steering column to drive the vehicle's steering wheel to move to a preset driving position, wherein the preset driving position refers to a position that is convenient for the driver to drive the vehicle.

[0102] Regarding step S21, the ambient temperature of the vehicle is monitored.

[0103] The ambient temperature is collected by the vehicle's external temperature sensor. The frequency of collecting the ambient temperature can be set according to actual conditions, or the frequency of collecting the ambient temperature by the vehicle itself can be used. The embodiment of the present application does not impose any restrictions on this.

[0104] Before or after executing step S21, a first environment preset temperature may be determined. The first environment preset temperature is used to judge whether the current environment is a low temperature environment, specifically, the temperature used to judge whether the probability of failure of the electric steering column in the current environment is high or low. The first environment preset temperature may be obtained according to industry standards, for example, it may be -30°C.

[0105] When the ambient temperature is greater than or equal to the first ambient preset temperature, step S211 and step S212 may continue to be executed.

[0106] Step S211, in response to a driver's door opening signal of the vehicle, controlling the electrically adjustable steering column to drive the steering wheel to move to the preset driving position.

[0107] Step S212, in response to the driver's seat belt unbuckle signal of the vehicle, controlling the electrically adjustable steering column to drive the steering wheel to move to a preset avoidance position, wherein the preset avoidance position is used to facilitate the driver to leave the driver's seat.

[0108] Regarding step S211, when the driver opens the driver's door, a driver's door opening signal is generated, which means that the driver needs to sit in the driver's seat. In response to the driver's door opening signal of the vehicle, the electric adjustable steering column can be controlled to drive the steering wheel to move to the preset driving position so that the driver can sit in the driver's seat to drive the vehicle.

[0109] The preset driving position is a position for the driver to drive the vehicle conveniently, and can be set according to the driver's own needs. In the embodiment of the present application, the mode in which the electric adjustment steering column drives the steering wheel to move to the preset driving position is recorded as the welcoming mode.

[0110] Regarding step S212, when the driver unbuckles the driver's seat belt, a driver's seat belt unbuckle signal is generated, which means that the driver needs to get off the vehicle. In response to the driver's seat belt unbuckle signal of the vehicle, the electrically adjustable steering column can be controlled to drive the steering wheel to move to the preset avoidance position to increase the space of the driver's seat so that the driver can leave the driver's seat.

[0111] The preset avoidance position is a position where the driver can leave the driving seat conveniently, and can be set according to the driver's own needs. In the embodiment of the present application, the mode in which the electrically adjustable steering column drives the steering wheel to move to the preset avoidance position is recorded as the courtesy mode.

[0112] When the ambient temperature is lower than the first ambient preset temperature, it indicates that the current environment is an environment where the electric adjustable steering column has a high probability of failure, and step S22 may be continued.

[0113] Regarding step S22, when the ambient temperature is less than a first ambient preset temperature, the passenger compartment temperature of the vehicle is monitored.

[0114] The temperature of the passenger compartment is collected by the vehicle's in-vehicle temperature sensor. The frequency of collecting the passenger compartment temperature can be set according to actual conditions, or the frequency of collecting the passenger compartment temperature by the vehicle itself can be used. The embodiment of the present application does not impose any restrictions on this.

[0115] When the ambient temperature is lower than the first ambient preset temperature, the passenger compartment temperature of the vehicle is monitored, and different strategies are adopted according to the different temperature stages of the passenger compartment temperature. Specifically, the first cabin preset temperature, the second cabin preset temperature, and the third cabin preset temperature are set in the embodiment of the present application, and four corresponding different temperature stages can be obtained. For details, please refer to Figure 3 Temperature axis diagram shown.

[0116] The first chamber preset temperature is less than or equal to the second chamber preset temperature, and the third chamber preset temperature is greater than or equal to the second chamber preset temperature. The present application embodiment provides a method for determining the second chamber preset temperature, specifically comprising steps S221-S222.

[0117] Step S221, measuring the limit driving temperatures corresponding to the various parts in the electrically adjustable steering column of the vehicle;

[0118] Step S222: determining the preset temperature in the second cabin according to the limit driving temperatures corresponding to the respective parts in the electrically adjustable steering column.

[0119] The preset temperature in the second compartment is used to judge whether the electric steering column is likely to fail in the current environment. The rotation, rotation or other actions of each part in the electric steering column are mainly achieved by lubricating oil and other oils. As the temperature of the lubricating oil decreases, its resistance will become greater and greater. When the resistance is greater than or equal to the driving force of the corresponding part in the electric steering column, the part will not be able to move. In the embodiment of the present application, the temperature corresponding to the moment when the part just fails to move is recorded as the limit driving temperature.

[0120] As the number of inoperable parts in the electric steering column increases, the failure of the electric steering column becomes more serious. Different parts of the electric steering column may have different limit driving temperatures.

[0121] In specific implementation, the corresponding highest extreme driving temperature in the electric adjustable steering column can be used as the second cabin preset temperature, which can basically avoid the failure of the electric adjustable steering column. However, this may lead to frequent implementation of subsequent step strategies, specifically frequent driving of the electric adjustable steering column and the steering wheel to switch between welcome mode and courtesy mode, causing wear of parts and affecting user experience.

[0122] In the embodiment of the present application, the relatively middle extreme driving temperature among the extreme driving temperatures corresponding to the multiple parts in the electric adjustable steering column can be used as the second cabin preset temperature. Although this cannot completely avoid the failure of the electric adjustable steering column, it can greatly reduce the probability of failure of the electric adjustable steering column and can also reduce the frequency of implementation of the subsequent step strategy. Specifically, it reduces the frequency of driving the electric adjustable steering column to carry the steering wheel to switch between the welcome mode and the courtesy mode, reduces the wear on the parts, and improves the user experience.

[0123] In the present embodiment, the preset temperature in the second cabin is -30°C as an example to illustrate the subsequent steps. Figure 3 The preset temperature in the first cabin may be the preset temperature in the second cabin itself, or may be lower than the preset temperature in the second cabin. In the embodiment of the present application, the preset temperature in the first cabin is -32°C as an example for subsequent description. The preset temperature in the third cabin may be the preset temperature in the second cabin itself, or may be higher than the preset temperature in the second cabin. In the embodiment of the present application, the preset temperature in the third cabin is -28°C as an example for subsequent description.

[0124] When the passenger compartment temperature is lower than the first cabin preset temperature, continue to execute step S23. When the passenger compartment temperature is equal to the second cabin preset temperature, continue to execute steps S31 to S33. When the passenger compartment temperature is higher than the second cabin preset temperature, continue to execute steps S41 to S42. When the passenger compartment temperature is higher than or equal to the third cabin preset temperature, continue to execute steps S51 to S52.

[0125] Regarding step S23, when the temperature of the passenger compartment is lower than the preset temperature in the first compartment, the vehicle's electrically adjustable steering column is controlled to drive the vehicle's steering wheel to move to a preset driving position, and the preset driving position refers to a position that is convenient for the driver to drive the vehicle.

[0126] When the passenger compartment temperature is lower than the preset temperature in the first compartment, it means that the possibility of failure of the electric adjustable steering column is very high. Therefore, it is necessary to control the electric adjustable steering column in advance to move the steering wheel to the preset driving position, that is, to put the electric adjustable steering column in the welcome mode. In this way, the electric adjustable steering column can be put in a normal driving state before the driver temporarily uses the vehicle, and the driver does not need to face the risk of failure of the electric adjustable steering column, and can start the vehicle normally after getting in the vehicle.

[0127] For example, at 2:00 a.m., if the temperature of the passenger compartment is detected to be lower than the preset temperature in the first compartment, the electric steering column is controlled to drive the steering wheel of the vehicle to move to the preset driving position, and the completion time is 2:10. At 3:00 a.m., the driver needs to drive to the hospital. At this time, the driver can directly start and drive normally after getting in the car, and no longer needs to wait for the electric steering column to move, which reduces the probability of the driver encountering failure of the electric steering column and improves the user experience.

[0128] However, if the relevant technology is adopted, at 3:00 in the morning, when the driver needs to use the car, the motor will start to drive the electric adjustable steering column when the driver opens the car door. Since the electric adjustable steering column is frozen, the driver will need to wait for more than ten minutes before driving normally, affecting the user experience.

[0129] Regarding steps S31 to S34:

[0130] Regarding step S31, when the temperature of the passenger cabin is equal to the preset temperature in the second cabin, obtain the temperature forecast data between the current moment and the preset moment in the future when the sun meets the target state, the target state refers to the preset state that the sun first meets after the current moment, and the preset state refers to sunrise or sunset; the preset temperature in the first cabin is less than or equal to the preset temperature in the second cabin.

[0131] When the temperature of the passenger compartment is equal to the preset temperature in the second compartment, the probability of failure of the electric adjustable steering column at this temperature is relatively small, but as time goes by and the temperature changes, the electric adjustable steering column may develop in a direction where the probability of failure increases, or the electric adjustable steering column may develop in a direction where the probability of failure decreases.

[0132] In order to further determine the possibility of the electric steering column failing in the future, the temperature forecast data between the current time and the preset time when the sun meets the target state in the future can be obtained, and the possibility of the electric steering column failing in the future can be predicted based on the temperature forecast data. The temperature forecast data can be weather forecast data obtained through the Internet.

[0133] For example, if the current time is afternoon, then the nearest target state of the sun is sunset, which will cause the temperature to drop further, which will cause the electric steering column to develop in the direction of increasing the probability of failure. For another example, if the current time is 3:00 a.m., then the nearest target state of the sun is sunrise, which will cause the temperature to rise, which will cause the electric steering column to develop in the direction of decreasing the probability of failure.

[0134] On this basis, the embodiment of the present application sets a preset ambient temperature for determining the possibility of failure of the electric adjustable steering column in the future due to future changes in ambient temperature.

[0135] When the temperature forecast data indicates that the temperature at the location of the vehicle will drop below the forecast ambient temperature in the future, it indicates that the electric adjustable steering column is more likely to fail in the future, and the process continues to step S32. When the temperature forecast data indicates that the temperature at the location of the vehicle will not drop below the forecast ambient temperature in the future, it indicates that the electric adjustable steering column is less likely to fail in the future, and the process continues to step S34.

[0136] Regarding step S32, when the temperature forecast data indicates that the temperature at the location of the vehicle will drop below the forecast ambient temperature in the future, it is determined whether the ambient temperature corresponding to the current moment is less than the forecast ambient temperature.

[0137] The temperature forecast data usually indicates the temperature data of a larger area, and there is a certain difference between the location of the vehicle and the temperature forecast data. Therefore, when the temperature forecast data indicates that the temperature of the local area where the vehicle is located will drop below the forecast ambient temperature in the future, it is necessary to determine whether the ambient temperature corresponding to the surroundings of the vehicle at the current moment is less than the forecast ambient temperature, so as to determine the influence of the actual ambient temperature around the vehicle on the possibility of failure of the electric steering column.

[0138] If the ambient temperature around the vehicle at the current moment is greater than or equal to the forecast ambient temperature, it means that the current location of the vehicle is warmer than the large area corresponding to the temperature forecast data. The current ambient temperature is less likely to cause the electric adjustable steering column to fail. The electric adjustable steering column can be controlled to maintain the current status and continue to return to step S21 to monitor the ambient temperature.

[0139] If the current ambient temperature around the vehicle is lower than the predicted ambient temperature, the process continues with step S33.

[0140] Regarding step S33, when the ambient temperature corresponding to the current moment is less than the predicted ambient temperature, the electrically adjustable steering column is controlled to drive the steering wheel to move to the preset driving position.

[0141] When the ambient temperature corresponding to the current moment is lower than the forecast ambient temperature, it means that the current location of the vehicle is colder than the large area corresponding to the temperature forecast data. The current ambient temperature is more likely to cause the electric steering column to fail. It is necessary to control the electric steering column in advance to move the steering wheel to the preset driving position, that is, to put the electric steering column in the welcome mode. In this way, the electric steering column can be put into a normal driving state before the driver temporarily uses the vehicle, and the driver does not need to face the risk of failure of the electric steering column, and can start the vehicle normally after getting in the vehicle.

[0142] Regarding step S34, when the temperature forecast data indicates that the temperature of the local area where the vehicle is located will not drop below the forecast ambient temperature in the future, the electrically adjustable steering column is controlled to maintain the current state.

[0143] When the temperature forecast data indicates that the local temperature of the vehicle will not drop below the forecast ambient temperature in the future, it indicates that the electric adjustable steering column is less likely to fail in the future, and the electric adjustable steering column can be controlled to maintain the current state and continue to return to step S21 to monitor the ambient temperature.

[0144] Regarding step S41-step S42, they are performed when the temperature of the passenger compartment is greater than or equal to the preset temperature in the second compartment.

[0145] Step S41, in response to a seat belt unbuckle signal of the vehicle, controlling the electrically adjustable steering column to drive the steering wheel to move to the preset avoidance position;

[0146] Step S42, in response to the driver's door opening signal of the vehicle, controlling the electrically adjustable steering column to drive the steering wheel to move to the preset driving position.

[0147] The principle of step S41 is similar to that of step S211, and the principle of step S42 is similar to that of step S212. For details, please refer to the relevant description of step S211-step S212, which will not be elaborated in the embodiment of the present application.

[0148] Regarding step S51-step S52:

[0149] Step S51, when the passenger compartment temperature is greater than or equal to the third cabin preset temperature, determine whether the ambient temperature corresponding to the current moment is greater than or equal to the passenger compartment temperature corresponding to the current moment; the third cabin preset temperature is greater than or equal to the second cabin preset temperature.

[0150] Step S52, when the ambient temperature corresponding to the current moment is greater than or equal to the passenger compartment temperature corresponding to the current moment, controls the electrically adjustable steering column to drive the steering wheel to move to a preset avoidance position, and the preset avoidance position is used to facilitate the driver to leave the driving seat.

[0151] Regarding step S51, when the temperature of the passenger compartment is greater than or equal to the preset temperature in the third cabin, continue to determine whether the corresponding ambient temperature at the current moment is greater than or equal to the temperature of the member cabin, that is, determine whether the temperature outside the vehicle is higher than the temperature inside the vehicle, and then determine whether the temperature inside the vehicle can rise with the temperature outside the vehicle.

[0152] When the ambient temperature corresponding to the current moment is lower than the passenger compartment temperature corresponding to the current moment, it is determined that the temperature outside the vehicle is lower than the temperature inside the vehicle, which means that the temperature inside the vehicle will continue to drop with the temperature outside the vehicle. At this time, the possibility of failure of the electric adjustable steering column is still high, and the electric adjustable steering column needs to be controlled to continue to maintain the welcome mode so that the driver can drive normally after getting in the vehicle.

[0153] When the ambient temperature corresponding to the current moment is greater than or equal to the passenger compartment temperature corresponding to the current moment, step S52 is continued.

[0154] Regarding step S52, when the ambient temperature corresponding to the current moment is greater than or equal to the passenger compartment temperature corresponding to the current moment, it is determined that the temperature outside the vehicle is higher than the temperature inside the vehicle, which means that the temperature inside the vehicle will rise with the temperature outside the vehicle. At this time, the possibility of failure of the electric adjustable steering column is reduced, and the electric adjustable steering column can be controlled to carry the steering wheel to the preset avoidance position, that is, switch to the courtesy mode, so that the driver can get on the vehicle more conveniently. At the same time, the electric adjustable steering column can also be controlled to drive the steering wheel to the preset driving position in response to the driver's door opening signal of the vehicle, ensuring that the driver can drive normally after getting on the vehicle.

[0155] For example, when it turns from day to night, the temperature drops. In order to ensure that the driver can use the car normally when he wants to use it at night, the electric adjustable steering column can be controlled in advance to drive the steering wheel to move to the preset driving position, ensuring that the driver can drive normally after getting in the car and reducing the chance of the driver facing failure of the electric adjustable steering column.

[0156] When the temperature rises from night to day, in order to ensure that the driver can enjoy the welcome and courtesy function, the electric adjustable steering column can be controlled to drive the steering wheel to move to the preset avoidance position after the temperature rises during the day. In this way, the electric adjustable steering column can be controlled to switch between welcome and courtesy without the driver's knowledge, which can reduce the probability of failure of the electric adjustable steering column and allow the driver to enjoy the courtesy welcome function when he wants to use the car during the day, reducing the driver's doubts about using the car and improving the user experience.

[0157] In summary, the embodiment of the present application monitors the ambient temperature of the vehicle when the vehicle is parked; monitors the passenger compartment temperature of the vehicle when the ambient temperature is less than the first ambient preset temperature; and controls the vehicle's electric adjustable steering column to drive the vehicle's steering wheel to a preset driving position when the passenger compartment temperature is less than the first cabin preset temperature. The preset driving position refers to a position that is convenient for the driver to drive the vehicle. It can be seen that the embodiment of the present application analyzes the ambient temperature and the passenger compartment temperature to determine whether it is necessary to control the vehicle's electric adjustable steering column in advance to drive the vehicle's steering wheel to the preset driving position, so as to realize the courtesy function of the electric adjustable steering column while ensuring driving priority. In this way, when the driver needs to use the car, the probability of failure of the electric adjustable steering column in a low temperature environment can be minimized to improve the user experience.
