Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
The all-terrain driving system collects data according to the characteristics of different road conditions, writes a scientific driving mode into the vehicle-mounted program, presets various road condition modes, and can automatically set the vehicle-mounted program according to different road conditions when a driver encounters complex terrain, so that the strongest performance of the vehicle can be exerted. The main strategy of the all-terrain driving System is stored in an Electronic Stability Program (ESP), and the ESP, a Torque On Demand (TOD), an Engine Management System (EMS), an automatic Transmission Control Unit (TCU), and an Electronic differential System (EGD) jointly form the whole Control System, so as to jointly complete the standard, economic, motion, snow, mud, sand, 4L, rock and other terrain modes and simultaneously take care of the escaping of various roads.
In the prior art, an all-terrain driving system controls each subsystem according to a terrain mode selected by a driver and in combination with road surface information, and informs the driver whether the terrain mode is successfully switched only through an instrument display system after the system is successfully judged, and no other related warning and data display prompts the driver in the off-road process.
Accordingly, the present invention provides an off-road vehicle auxiliary control method to solve the above problems.
Fig. 1 is a schematic flow chart of an implementation process of an off-road vehicle auxiliary control method provided by an embodiment of the invention, and referring to fig. 1, the method includes the following steps:
and step S101, acquiring the terrain mode currently selected by the all-terrain vehicle driving system.
In embodiments of the present invention, terrain modes include, but are not limited to, standard, economy, sport, snow, mud, sand, 4L, etc. modes. The standard mode is suitable for normal running (roads, paved roads, asphalt roads and the like) under common working conditions, and is the most comfortable driving mode. The fuel consumption of the vehicle can be reduced in the economy mode. The sport mode is suitable for fast driving under good road conditions, such as urban high-rise or inter-city high speed, and provides the driving state with the most sports fun. The snow mode is mainly used for a firm and slippery road surface on the ground such as ice and snow. The mud mode is suitable for muddy, deep-furrow, loose or uneven road surfaces. The sand mode is suitable for dry sand with certain yield strength, such as dry sand, sand beach, sand dune and desert. The 4L mode is suitable for the working condition that large torque is needed for advancing at low speed, such as escaping, and the torque of the vehicle is amplified by 2.48 times in the mode.
And step S102, displaying various parameter values of the vehicle in the all-terrain driving control interface of the vehicle display screen.
In this embodiment, the conventional all-terrain driving system only informs a driver of whether the terrain mode is successfully switched through the instrument display system, and people with relatively poor off-road experience are difficult to accurately control various data of the vehicle, so that the system is easy to operate improperly, and the vehicle loses power and even has accidents.
In the embodiment, the driver can conveniently monitor important parameters in real time by creating the all-terrain driving control interface (or called the off-road information state display interface). Specifically, the host HUT of vehicle is through the mode switch request signal that discernment global control ware ATS sent, and after judging that the mode switch is successful, HUT passes through vehicle display screen display mode information, if mode switch request signal is not received once more in the certain time, global control ware ATS sends the request to HUT and carries out vehicle parameter state and show, and HUT shows each item important parameter value of vehicle in order to monitor through the cross-country information state display interface of display screen. A (c)
The parameters include, but are not limited to, engine speed, tire pressure, engine water temperature, transmission temperature, transfer case temperature, engine turbine pressure, and the like.
The display screen may be a multimedia screen of a vehicle or an instrument screen.
And step S103, judging whether each parameter value exceeds a prompt value corresponding to each parameter in the current terrain mode, and prompting a user if the parameter value exceeds the prompt value. The prompt values corresponding to the various parameters in the current terrain mode are preset by a user, and the prompt values corresponding to the various parameters are smaller than the preset danger alarm threshold values corresponding to the various parameters.
In this embodiment, the vehicle is generally preset with a danger alarm threshold of each parameter, and when each parameter value exceeds the danger alarm threshold, the vehicle may malfunction. In order to guide the driver to safely use the vehicle in the off-road condition, the driver can set the prompt values of all parameters by himself/herself, the prompt values are lower than the danger alarm threshold, for example, the danger alarm threshold of the engine water temperature is 120 ℃, and the prompt value of the engine water temperature can be set to 110 ℃, so that danger prompt is performed in advance, the driver is guided to operate the vehicle correctly, and the situation that the vehicle loses power or fails due to the fact that some important parameters exceed the danger alarm threshold is avoided.
Therefore, the embodiment of the invention displays various parameter values of the vehicle in the all-terrain driving control interface of the vehicle display screen, is convenient for users to accurately control key data and various functions of the vehicle in the off-road process, and avoids the limitation of vehicle running caused by vehicle faults or various alarms due to wrong driving; and moreover, by presetting the prompt values corresponding to all the parameters, the prompt values corresponding to all the parameters are smaller than the preset danger alarm threshold values corresponding to all the parameters, and when all the parameter values exceed the prompt values corresponding to all the parameters in the current terrain mode, a user is prompted, early warning can be performed before the vehicle loses power or breaks down, the correct and safe vehicle using of the user is guided, and the cross-country experience and the vehicle passing performance are improved.
In one possible implementation manner, in step S102, the parameters of the vehicle include, but are not limited to, at least one of the following:
engine water temperature, transmission temperature, transfer case temperature, and engine turbine pressure.
In this embodiment, because of the cross-country operating mode is comparatively abominable, especially in-process such as desert topography rushes to the slope, easily leads to the vehicle to lose power because of the temperature is too high, causes driving danger, consequently cross-country in-process accessible cross-country information state display interface shows the engine temperature to help the driver to acquire current operating condition. According to the arrangement state of the thermostat, a driver can set a prompt value of the initial opening temperature of a main valve of the thermostat through an all-terrain driving control interface, when the water temperature of an engine reaches the prompt value, the driver is prompted to cautiously drive a vehicle by sending prompt information, the off-road behavior of the vehicle is stopped, and the danger caused by the loss of the power of the vehicle is avoided.
In one embodiment, the user can also input an electronic fan threshold setting instruction through the all-terrain driving control interface, so that the starting threshold of the electronic fan of the vehicle can be adjusted. The electronic fan of the vehicle is controlled by a temperature controller, and the electronic fan is used for controlling the water temperature of the engine not to be too high and comprises a sensor, the electronic fan, a chip and the like. When the water temperature of the engine generally exceeds 90 ℃, the electronic fan is started to reduce the water temperature. The opening threshold value of the electronic fan of the vehicle is reduced, so that the fan is opened in advance to help the engine to dissipate heat, and the cross-country performance of the vehicle is improved.
Similarly, in the vehicle pit escaping process in cross country, the wheel skids and easily leads to the derailleur friction disc and the friction disc of transfer case to rub, can lead to derailleur or transfer case oil temperature too high warning after a period of time, the overheated meeting of derailleur leads to the vehicle to lose power, the overheated meeting of transfer case leads to the unable work of four-wheel drive system, both can lead to vehicle power to be restricted, consequently, drive control interface display derailleur and transfer case temperature through all topography, make things convenient for the driver to observe the temperature variation of relevant system, and through setting for the prompt value, the suggestion driver relevant system is about to overheat after reaching the prompt value, can avoid the relevant system of vehicle overheat running risk.
The pressure value display of the engine turbine is added, so that a driver can observe the intervention time of the engine turbine and the change of the internal pressure value conveniently, and then the power state and the power output trend of the vehicle are judged, the driver can better master the vehicle operation parameters to drive the vehicle, and the safety and the cross-country trafficability of the vehicle are improved.
It should be pointed out that the all-terrain driving control interface of the embodiment can not only display the water temperature of the engine, the temperature of the transmission, the temperature of the transfer case and the pressure value of the turbine, but also display the parameters such as the rotating speed of the engine according to actual requirements, and if other related parameters need to be added, the monitoring can be carried out through OTA (over the air) for pushing and upgrading.
As a possible implementation manner, after acquiring the terrain mode currently selected by the all-terrain driving system of the vehicle in step S101, the method may further include:
detecting the terrain of the current position of the vehicle;
and judging whether the terrain is matched with the terrain mode currently selected by the vehicle all-terrain driving system, and if not, prompting the user to switch to the terrain mode corresponding to the terrain.
In real life, a driver may forget to switch the terrain mode when traveling off-road, for example, the driver may keep the former standard mode when traveling on sand, or forget to switch back to the standard mode after returning off-road, which is not favorable for the vehicle to exhibit the best performance.
As a possible implementation manner, after acquiring the terrain mode currently selected by the all-terrain driving system of the vehicle in step S101, the method may further include:
and judging whether the starting time of the all-terrain driving system reaches a preset time threshold, if so, displaying various parameter values of the vehicle in the all-terrain driving control interface of the vehicle display screen, and otherwise, not displaying various parameter values of the vehicle in the all-terrain driving control interface of the vehicle display screen.
In this embodiment, the HUT displays the mode information by recognizing the mode switching request signal sent by the all-terrain controller, and when it is determined that the mode switching is successful, the all-terrain controller sends a request to the HUT to display the vehicle parameter state when it is determined that there is no all-terrain mode switching request within a certain time limit. The design can realize the technical effects that the parameter display is not carried out under the conditions of starting the all-terrain driving system and the like by mistake touch and the parameter display is carried out only when the cross-country requirement is really met through certain time delay.
Therefore, in this embodiment, the ATS can identify the current terrain of the vehicle, and if the current terrain is not matched with the terrain mode of the vehicle as shown in the identification result, a prompt message is sent to the HUT for mode switching prompt, where the prompt mode may be a voice prompt or a prompt through a display screen of the vehicle.
The formulation of the strategy is beneficial to guiding a novice off-road to use the vehicle correctly and safely.
In one embodiment, the method for identifying the terrain where the vehicle is currently located comprises:
acquiring position information of a vehicle, a tire slip rate change rate and a vehicle yaw angle change rate;
determining at least one alternative terrain according to the position information;
and selecting one alternative terrain from at least one alternative terrain according to the change rate of the tire slip rate and the change rate of the yaw angle of the vehicle, wherein the alternative terrain is used as the terrain of the current position of the vehicle.
In the present embodiment, the ATS can analyze the terrain more accurately by recognizing the vehicle tire slip rate change rate and the vehicle yaw angle change rate and confirming the current terrain where the vehicle is located in conjunction with the GPS. For example, if the current terrain is determined to be one of sand, mud, and snow (different terrain in different seasons and weather) based on the position information, the current terrain can be further determined from the tire slip rate change rate and the vehicle yaw angle change rate.
In one embodiment, the method for identifying the terrain at which the vehicle is currently located may further comprise:
a360-degree image acquisition device installed on the vehicle is used for acquiring a terrain image of the current position of the vehicle, and the terrain of the current position of the vehicle is determined through an image analysis and classification method.
As a possible implementation manner, after acquiring the terrain mode currently selected by the all-terrain driving system of the vehicle in step S101, the method may further include:
judging whether the vehicle is in a manual gear mode at present;
if the vehicle is in the manual gear mode, acquiring the current speed of the vehicle;
and according to the current speed and a preset speed range corresponding to each gear in the terrain mode currently selected by the vehicle all-terrain driving system, gear shifting prompt is carried out on the user.
In this embodiment, during off-road operation, the gear shift needs to be switched to manual mode in order to switch the gear shift according to the operating condition and the dynamic performance of the vehicle, and the maximum basis for the gear shift is the vehicle speed. Through for the different speed range of shifting gears of different topography pattern matching, the suggestion of shifting gears according to the speed range of shifting gears of setting for under each mode makes things convenient for the better vehicle of controlling of driver, makes the vehicle keep good power output, is favorable to promoting the dynamic performance and the vehicle trafficability characteristic of vehicle.
As a possible implementation manner, when the user preset the prompt values corresponding to the various parameters in the various terrain modes, the method may further include:
acquiring configuration data of the vehicle related to various parameters, and determining the optimal setting range of the prompt values of various parameters of the vehicle in different terrain modes according to the configuration data;
and pushing the optimal setting range of the prompt value corresponding to each parameter to the user through the all-terrain driving control interface so that the user can set the prompt value of each parameter according to the optimal setting range of the prompt value.
In the present embodiment, the optimum setting ranges of the indicated values of the respective parameters are different for vehicles of different configurations, for example, the optimum setting ranges of the indicated values of the engine water temperature and the engine turbine pressure are related to the model of the vehicle engine, and the like. The optimal setting range of the prompt value corresponding to different configuration data can be stored in advance, and after the configuration data of the vehicle is obtained, the corresponding optimal setting range of the prompt value can be known in a table look-up mode and the like, so that the scheme can be applied to different vehicles. The optimal setting ranges of the prompting values of various parameters of the vehicle under different terrain modes are different generally. Aiming at the prompt value setting of each important parameter, the optimal setting range pushing function of the prompt value is added, so that the setting by customers with insufficient experience is facilitated, and guidance is provided for the customers to correctly use the vehicles. The user can also directly perform one-key setting on the optimal setting range of the prompt values of the pushed parameters, and can perform independent setting or single-key setting on the prompt values of the parameters.
In combination with the above, the embodiment of the invention provides a vehicle off-road auxiliary control method, based on the influence of relevant parameters on the off-road performance of a vehicle in the off-road process, a full-terrain controller displays parameter states through interaction with a HUT, a sensor is used for acquiring the water temperature of an engine, the temperature of a transmission, the temperature of a transfer case and the pressure of a turbine of the engine, and prompt values of various parameters are set for safety prompt, so that a driver can better master vehicle operation parameters to drive the vehicle, the problem that the important parameters are not relevant to display and early warn in the off-road process of the vehicle is solved, the problem of vehicle power failure possibly caused by insufficient driving experience in the off-road process is avoided, the safety and the trafficability of the vehicle in complex terrain working conditions are increased, and the failure rate of the vehicle is reduced.
