The technical solution is described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0029] The shortage of energy and people's higher requirements for quality of life are the main reasons for the development of electric vehicles. With the deepening of the global energy crisis, the depletion of oil resources, the increasing harm of air pollution and global temperature rise, people generally realize that energy conservation and emission reduction are the main directions for the development of future automobile technology. As a new generation of transportation, electric vehicles have incomparable advantages over fuel vehicles in terms of energy conservation and emission reduction and reducing human dependence on traditional energy.

[0030] As an example, in actual applications, the economic mode is usually used to save the electric energy of electric vehicles. The economic mode is to send a control signal through the vehicle controller to reduce the torque of the vehicle, control the torque within a more economical range, and then change the pedal of the vehicle's power response to achieve higher driving efficiency and save energy. At the same time, the remaining electricity is recycled into the battery, and more electricity is recycled to reduce energy consumption and improve battery life. However, saving electricity only through power is very limited in an era of increasingly prosperous electrification, and cannot meet the growing demand for intelligence.

[0031] In one embodiment of the present application, the vehicle computer provides a super power saving system, which formulates a power saving mode of a relevant level according to the relevant information provided by the vehicle computer, thereby providing a more comfortable driving environment for the user while maximizing the vehicle's endurance.

[0032] The vehicle computer monitors the on / off state of the super power saving system. When the super power saving system is activated, the vehicle computer immediately prompts the user whether to turn on the navigation.

[0033] The vehicle computer includes an information monitoring module, which monitors various physical information of the vehicle computer in real time. In one embodiment of the present invention, the information monitoring module is implemented as a VCU to obtain various parameters of the vehicle, including but not limited to vehicle speed, power consumption, cruising range, ambient temperature, navigation distance, charging pile distance, etc.

[0034] The vehicle computer includes an information processing module, which obtains and processes the data in the information monitoring module. In one embodiment of the present invention, the obtained cruising range and navigation distance are processed to obtain a mileage margin. The information processing module divides the super power saving system into at least one target power saving level according to a preset threshold. In the present invention, there are 4 power saving levels.

[0035] The vehicle computer includes an information execution module, and the information execution module executes corresponding intelligent control of the vehicle according to the target power saving level.

[0036] The technical content provided by this application is intended to solve the above-mentioned technical problems of related technologies. In the embodiment of this application, it is detected whether the navigation function is in the on state. If the navigation is in the on state, the current state parameters are obtained, and the state parameters include the cruising range and the navigation distance; according to the current state parameters, the current mileage margin is calculated, and the mileage margin is the ratio of the cruising range and the navigation distance; then according to the current mileage margin and the mileage margin interval corresponding to each power saving level, the power saving level corresponding to the current mileage margin is used as the target power saving level. If the current ambient temperature exceeds the preset temperature range, the higher level of the target power saving level is used as the updated target power saving level, and the vehicle control is performed according to the target power saving level. In the scheme of this application, when the navigation is turned on, the target power saving level is calculated by identifying the current remaining cruising range of the vehicle and the distance to the destination of the navigation, and the final target power saving level is determined according to the current ambient temperature of the vehicle, so as to perform intelligent control of the vehicle. Under the condition of not affecting the user's driving experience as much as possible, some devices in the vehicle can be optimized, turned off or disabled with one click, so as to timely and flexibly adjust the vehicle's power consumption level in the scenario of electric vehicle intelligence, ensure the vehicle's range in the scenario of intelligent vehicle, and solve the problem of range anxiety. In addition, this solution can meet personalized driving needs.

[0037] Some aspects of the examples of this application relate to the above considerations. The following is an example introduction of the solution in combination with some examples.

[0038] Figure 1 A flow chart of a vehicle control method provided by an example of the present application is shown in FIG. 1 . The execution subject of this example may be a vehicle control device, such as Figure 1 As shown, the method includes:

[0039] Step 101: Detect whether the navigation function is turned on. If the navigation is turned on, obtain the current state parameters; the state parameters include the cruising range and the navigation distance;

[0040] Step 102: Calculate and obtain the current mileage margin value according to the current state parameters; the mileage margin value is the ratio of the cruising range to the navigation distance;

[0041] Step 103, based on the current mileage margin and the mileage margin intervals corresponding to each power saving level, the power saving level corresponding to the current mileage margin is used as the target power saving level. If the current ambient temperature exceeds the preset temperature range, a higher level of the target power saving level is used as the updated target power saving level, and the vehicle is controlled according to the target power saving level; wherein, different power saving levels have different control strategies, and different vehicle functional states have different control strategies.

[0042] In practical applications, the executor of the method can be a vehicle control device, and there are many ways to implement it. For example, it can be implemented through a computer program, such as application software, etc.; or, it can be implemented as a medium storing relevant computer programs, such as a USB flash drive, a cloud disk, etc.; or, it can be implemented through a physical device that integrates or installs relevant computer programs, such as a chip, etc.

[0043] In this example, the vehicle computer monitors the on / off status of the super power saving system. When the super power saving system is activated, the vehicle computer will immediately prompt the user whether to turn on navigation. When it is detected that the navigation is on, the two state parameters of cruising range and navigation distance are obtained through the level information package of the information monitoring module. Among them, the cruising range is the remaining range currently calculated based on the remaining battery power. The remaining range refers to the distance from the start of driving until the electric vehicle stops due to lack of power under the current battery power, that is, the distance that supports continuous driving with the current battery power. The navigation distance is the distance from the driver turning on navigation to the destination. After obtaining the two state parameters of cruising range and navigation distance, the current mileage margin is calculated by dividing the cruising range by the navigation distance.

[0044] Specifically, after obtaining the target power saving level based on the calculated current mileage margin and the mileage margin interval corresponding to each power saving level, it is also necessary to consider the impact of the ambient temperature around the vehicle on the target power saving level. If the current ambient temperature around the vehicle exceeds the preset temperature range, it is necessary to use a higher level of the target power saving level as the updated target power saving level and perform corresponding vehicle control. For example, the temperature range can be set to above 35 degrees Celsius and below 0 degrees Celsius. For example, assuming that according to the current mileage margin and the mileage margin interval corresponding to each power saving level, the target power saving level is the second level, but the current ambient temperature around the vehicle is 38 degrees Celsius. At this time, the ambient temperature around the vehicle exceeds the preset temperature range, and it is necessary to use a higher level of the target power saving level as the target power saving level, that is, use the third level as the final target power saving level, and perform the control of the vehicle corresponding to the third level.

[0045] Among them, different power saving levels have different control strategies for vehicles, and different vehicle control strategies correspond to different vehicle functional states. For example, the power saving level can be divided into the first level, the second level, the third level and the fourth level. If the determined target power saving level is the first level, the vehicle control strategy corresponding to the first level is executed, corresponding to the vehicle functional state under the control strategy; if the determined target power saving level is the second level, the vehicle control strategy corresponding to the second level is executed, corresponding to the vehicle functional state under the control strategy; if the determined target power saving level is the third level, the vehicle control strategy corresponding to the third level is executed, corresponding to the vehicle functional state under the control strategy; if the determined target power saving level is the fourth level, the vehicle control strategy corresponding to the fourth level is executed, corresponding to the vehicle functional state under the control strategy. The vehicle functional state includes but is not limited to the maximum speed limit, energy recovery level adjustment, whether the air conditioner is turned on, etc.

[0046] In the vehicle control method provided in this example, firstly, it is detected whether the navigation function is turned on. If the navigation is turned on, the current vehicle's cruising range and navigation distance are obtained, and the current mileage margin is calculated. Then, according to the current mileage margin and the mileage margin interval corresponding to each power saving level, the power saving level corresponding to the current mileage margin is used as the target power saving level. If the current ambient temperature exceeds the preset temperature range, the higher level of the target power saving level is used as the updated target power saving level, and the vehicle control is performed according to the target power saving level. In the scheme of this example, when the navigation is turned on, the target power saving level is calculated by identifying the current remaining cruising range of the vehicle and the distance to the destination by navigation, and the final target power saving level is determined according to the current ambient temperature of the vehicle, so as to control the vehicle intelligently, and timely and flexibly adjust the vehicle's power consumption level under the condition of not affecting the user's driving experience as much as possible, to ensure the cruising range of the vehicle in the intelligent scenario and solve the problem of mileage anxiety.

[0047] In one example, each power saving level includes the first level, the second level, the third level and the fourth level; the mileage margin interval corresponding to the first level is not less than 1.2; the mileage margin interval corresponding to the second level is not less than 1.0 and less than 1.2; the mileage margin interval corresponding to the third level is not less than 0.8 and less than 1.0; the mileage margin interval corresponding to the fourth level is less than 0.8. For example, the power saving level can be set to the first level, the second level, the third level, and the fourth level. The mileage margin interval corresponding to the first level can be divided into not less than 1.2; the mileage margin interval corresponding to the second level can be divided into not less than 1.0 and less than 1.2; the mileage margin interval corresponding to the third level can be divided into not less than 0.8 and less than 1.0; the mileage margin interval corresponding to the fourth level can be divided into less than 0.8. Combined with the above example, the calculated mileage margin is 1.2, which belongs to the mileage margin interval of not less than 1.2. In this case, the corresponding power saving level is the first level, and the first level is used as the target power saving level, and the vehicle control corresponding to the first level is executed. It should be noted that the difference of 0.2 between the range values ​​of the mileage margin is considered that for ordinary users, the vehicle battery needs to be charged urgently when the last 20% of the power is left, so the mileage margin interval is set to determine the corresponding power saving level of the current vehicle. In the above example, by dividing the power saving level and the mileage margin interval corresponding to the power saving level, the whole vehicle is intelligently controlled to better save the vehicle's electrical energy.

[0048] Based on the above example, the method further includes: if the navigation function is not turned on, taking the second level as the target power saving level.

[0049] Specifically, if the driver does not turn on the navigation, the second level is directly used as the target power saving level, and the vehicle control strategy corresponding to the second level is executed, corresponding to the vehicle function state of the second level. In the above example, when the vehicle does not turn on the navigation, the corresponding vehicle control strategy is executed, which reduces the energy consumption of the vehicle and saves electricity.

[0050] Optionally, when the driver turns on navigation, after obtaining the vehicle's current range and navigation distance, before step 102, the method also includes: obtaining the distance between the nearest charging pile and the current vehicle position; if the range is not greater than the distance, taking the fourth level as the target power saving level; step 102 specifically includes: if the range is greater than the distance, calculating the current mileage margin based on the current state parameters.

[0051] Specifically, when navigation is turned on, based on the current range and navigation distance of the vehicle, before calculating the current mileage margin, the distance between the current nearest charging post and the current vehicle position must be obtained. This distance is the distance of the current nearest available charging column identified by the vehicle navigation. If the obtained range is not greater than this distance, the fourth level is used as the target power saving level, and the corresponding vehicle control is performed; if the obtained range is greater than this distance, the current mileage margin is continued to be calculated, and the corresponding power saving level is obtained according to the mileage margin interval corresponding to the current mileage margin, and the corresponding vehicle control is performed. In the above example, when navigation is turned on, it is determined whether the range is greater than the distance between the current nearest charging post and the current vehicle position, and the vehicle is divided into power saving levels taking into account the convenience of energy replenishment, thereby saving electricity while meeting driving needs.

[0052] Specifically, in step 103, the vehicle control is performed according to the target power saving level, specifically including: if the target power saving level is the first level, the vehicle control is performed according to the control strategy corresponding to the first level; the control strategy corresponding to the first level includes: the maximum speed is not limited, the energy recovery level is adjusted to the intermediate level; the automatic driving function is turned off, and other auxiliary driving functions except the automatic driving function are retained; the air conditioner is switched to ECO mode, the seat massage, heating, and ventilation functions are turned off, and the cockpit expansion function is supported; and the application is supported;

[0053] If the target power saving level is the second level, the vehicle control is performed according to the control strategy corresponding to the second level; the control strategy corresponding to the second level includes: the maximum speed is limited to 120 km / h, the energy recovery level is adjusted to high level; the automatic driving function is turned off, and other auxiliary driving functions except collision warning, lane keeping and departure warning, parking assistance, driving recorder and emergency recording function are turned off; the air conditioner is switched to ECO mode, the seat massage, heating and ventilation functions are disabled, and the cabin expansion function is turned off; support the opening of applications;

[0054] If the target power saving level is the third level, the vehicle control is performed according to the control strategy corresponding to the third level; the control strategy corresponding to the third level includes: the maximum speed is limited to 100 km / h, the energy recovery level is adjusted to high level; the automatic driving function is turned off, and other auxiliary driving functions except collision warning, reversing radar, driving recorder and emergency recording function are turned off; the air conditioner is turned off, the seat massage, heating and ventilation functions are disabled, and the cockpit expansion function is disabled; the application is closed;

[0056] Among them, each target power saving level can control the vehicle according to four aspects: power, intelligent driving, cockpit, and entertainment audio and video.

In terms of intelligent driving, the automatic driving function and other assisted driving functions are disabled and cannot be manually turned on again, and all the hosts, controllers, and sensors related to intelligent driving are dormant. In terms of the cockpit, the air conditioning, seat massage, heating, and ventilation functions are disabled, and the cockpit expansion function is disabled and cannot be manually turned on again. In terms of entertainment and audio-visual, entertainment and audio-visual and third-party applications are disabled and cannot be manually turned on again.

[0061] Among them, energy recovery adjustment to intermediate, advanced, and highest levels means adjusting the gear of energy recovery adjustment on the vehicle to intermediate, advanced, and highest levels. The corresponding electric energy recovery amount may be different for different vehicles. The energy recovery gear can be adjusted according to the actual vehicle situation. The cockpit expansion function refers to other functions that can be realized in the cockpit, such as car refrigerators, car theaters, and car holographic images. Kick-down breakthrough means that when the vehicle needs to accelerate sharply or needs to increase the driving force quickly during driving, in order to quickly obtain sufficient acceleration power, the driver breaks through the current driving restrictions, presses the accelerator to the bottom and forces the car to downshift to get enough driving force.

[0062] Through the solution of this example, the vehicle's maximum speed, power response, energy recovery, air conditioning performance, assisted driving, entertainment and audio-visual, and vehicle expansion functions are optimized, turned off or disabled, and one-click operation is achieved to achieve the current best endurance and energy consumption. In addition, this solution can meet personalized driving needs.

[0063] In addition, taking into account the actual control of the vehicle, based on any of the aforementioned examples, the method also includes: if the target power saving level determined this time is different from the target power saving level determined last time, detecting whether the current moment and the last moment are in the same driving cycle; wherein a single driving cycle represents the period from power-on to power-off of the vehicle; if they are in the same driving cycle, continuing to control the vehicle according to the target power saving level determined last time; otherwise, controlling the vehicle according to the target power saving level determined this time.

[0064] Specifically, if the target power saving level determined this time is different from the target power saving level determined last time, it is necessary to detect whether the current moment is in the same driving cycle as the last moment. A single driving cycle refers to the period from when the vehicle is powered on and starts driving after the current target power saving level is determined until the vehicle is powered off at the end of driving. If the current moment is in the same driving cycle as the last moment, the corresponding vehicle control is performed according to the target power saving level determined last time; if the current moment is not in the same driving cycle as the last moment, the corresponding vehicle control is performed according to the target power saving level determined this time. In the above example, before the vehicle is powered on and starts driving, the target power saving level in this driving cycle is determined, and switching the target power saving level is not allowed in the same driving cycle. When a driving cycle is restarted, the target power saving level will be determined again to prevent unexpected risks caused by the jump of the target power saving level.

[0065] In the vehicle control method provided in this example, it is detected whether the navigation function is in the on state. If the navigation is in the on state, the current state parameters are obtained, and the state parameters include the cruising range and the navigation distance; then the current mileage margin is calculated based on the current state parameters, and the mileage margin is the ratio of the cruising range to the navigation distance; then according to the current mileage margin and the mileage margin interval corresponding to each power saving level, the power saving level corresponding to the current mileage margin is used as the target power saving level. If the current ambient temperature exceeds the preset temperature range, the higher level of the target power saving level is used as the updated target power saving level, and the vehicle control is performed according to the target power saving level; wherein, the control strategies for different power saving levels are different, and the vehicle function states for different control strategies are different. The scheme of the present application, when the navigation is turned on, calculates the target power saving level by identifying the current remaining cruising range of the vehicle and the distance to the destination for navigation, and determines the final target power saving level according to the current ambient temperature of the vehicle, thereby performing intelligent control of the vehicle. Under the condition of not affecting the user's driving experience as much as possible, some devices in the vehicle can be optimized, turned off or disabled with one click, so as to timely and flexibly adjust the vehicle's power consumption level in the scenario of electric vehicle intelligence, ensure the vehicle's range in the scenario of intelligent vehicle, and solve the problem of range anxiety. In addition, this solution can meet personalized driving needs.

[0066] The vehicle control method provided in this application is described in detail below using a specific example. Figure 2 A flow chart of a vehicle control method provided as an example of the present application, such as Figure 2 As shown, the vehicle control process is as follows:

[0067] Step 201, detecting whether the navigation function is turned on; if the navigation function is not turned on, executing step 202; if the navigation function is turned on, executing step 203;

[0068] Step 202, directly determine that the target power saving level in this case is the second level, and execute step 207;

[0069] Step 203, obtaining the current cruising range, navigation distance, and the distance between the nearest charging pile and the current vehicle position, and executing step 204;

[0070] Step 204, detecting whether the current cruising range is not greater than the distance between the current nearest charging pile and the current vehicle position; if the current cruising range is not greater than the distance between the current nearest charging pile and the current vehicle position, executing step 205; if the current cruising range is greater than the distance between the current nearest charging pile and the current vehicle position, executing step 206;

[0071] Step 205, directly determine that the target power saving level in this case is the fourth level, and execute step 207;

[0072] Step 206, calculating the ratio of the cruising range to the navigation distance to obtain the current mileage margin, determining the target power saving level according to the mileage margin and the mileage margin intervals corresponding to each power saving level, and executing step 207;

[0073] Step 207, if the ambient temperature is greater than the preset temperature range, a higher level of the current target power saving level is used as the final target power saving level;

[0074] Step 208, according to the final target power saving level, corresponding vehicle control is performed, the whole vehicle is powered on, and starts driving.

[0075] Among them, the specific method of vehicle control can refer to the content of the above example. In summary, the vehicle control method provided in this example intelligently controls the vehicle according to each target power saving level for different situations, and optimizes, shuts down or disables some equipment in the vehicle with one click without affecting the user's driving experience as much as possible. In this way, in the scenario of electric vehicle intelligence, the power consumption level of the vehicle can be adjusted in a timely and flexible manner to ensure the cruising range in the scenario of vehicle intelligence and solve the problem of mileage anxiety. In addition, this solution can meet personalized driving needs.

[0076] Figure 3 FIG. 4 is a schematic diagram showing a structure of a vehicle control device provided by an example of the present application. Figure 3 As shown, the device comprises:

[0077] The first processing module 31 is used to detect whether the navigation function is in an on state. If the navigation is in an on state, the current state parameters are obtained; the state parameters include the cruising range and the navigation distance; the calculation module 32 is used to calculate the current mileage margin value according to the current state parameters; the mileage margin value is the ratio of the cruising range and the navigation distance;

[0078] The second processing module 33 is used to use the power saving level corresponding to the current mileage margin as the target power saving level according to the current mileage margin and the mileage margin interval corresponding to each power saving level. If the current ambient temperature exceeds the preset temperature range, a higher level of the target power saving level is used as the updated target power saving level, and the vehicle is controlled according to the target power saving level; wherein, the control strategies for different power saving levels are different, and the vehicle functional states of different control strategies are different.

[0079] In practical applications, there are many ways to implement the vehicle control device. For example, it can be implemented through a computer program, such as application software, etc.; or it can be implemented as a medium storing relevant computer programs, such as a USB flash drive, a cloud disk, etc.; or it can be implemented through a physical device that integrates or installs relevant computer programs, such as a chip.

[0080] In this example, the vehicle computer monitors the on / off status of the super power saving system. When the super power saving system is activated, the vehicle computer will immediately prompt the user whether to turn on navigation. When it is detected that the navigation is on, the two state parameters of cruising range and navigation distance are obtained through the level information package of the information monitoring module. Among them, the cruising range is the remaining range currently calculated based on the remaining battery power. The remaining range refers to the distance from the start of driving until the electric vehicle stops due to lack of power under the current battery power, that is, the distance that supports continuous driving with the current battery power. The navigation distance is the distance from the driver turning on navigation to the destination. After obtaining the two state parameters of cruising range and navigation distance, the current mileage margin is calculated by dividing the cruising range by the navigation distance.

[0081] Specifically, after obtaining the target power saving level based on the calculated current mileage margin and the mileage margin intervals corresponding to each power saving level, it is also necessary to consider the impact of the ambient temperature around the vehicle on the target power saving level. If the current ambient temperature around the vehicle exceeds the preset temperature range, a higher target power saving level needs to be used as the updated target power saving level and corresponding vehicle control needs to be performed.

[0082] Different power saving levels have different control strategies for vehicles, and different vehicle control strategies correspond to different vehicle functional states. The vehicle functional states include but are not limited to the maximum speed limit, energy recovery level adjustment, whether the air conditioner is turned on, etc.

[0083] In the above example, first check whether the navigation function is turned on. If the navigation is turned on, obtain the current vehicle's cruising range and navigation distance, calculate the current mileage margin, and then use the current mileage margin and the mileage margin interval corresponding to each power saving level as the target power saving level. If the current ambient temperature exceeds the preset temperature range, use the target power saving level as the next higher level and perform vehicle control according to the target power saving level. In this example, when navigation is turned on, the target power saving level is calculated by identifying the vehicle's current remaining cruising range and the navigation distance to the destination, and the final target power saving level is determined based on the current ambient temperature of the vehicle, so as to control the vehicle intelligently. Under the condition of not affecting the user's driving experience as much as possible, the vehicle's power consumption level is adjusted in a timely and flexible manner to ensure the vehicle's cruising range in intelligent scenarios and solve the problem of mileage anxiety.

[0084] In one example, each power saving level includes the first level, the second level, the third level and the fourth level; the mileage margin interval corresponding to the first level is not less than 1.2; the mileage margin interval corresponding to the second level is not less than 1.0 and less than 1.2; the mileage margin interval corresponding to the third level is not less than 0.8 and less than 1.0; the mileage margin interval corresponding to the fourth level is less than 0.8. In the above example, by dividing the power saving levels and the mileage margin intervals corresponding to the power saving levels, the whole vehicle is intelligently controlled to better save the vehicle's electrical energy.

[0085] Based on the above example, the device further includes: a third processing module, which uses the second level as the target power saving level if the navigation function is not turned on.

[0086] Specifically, if the driver does not turn on the navigation, the second level is directly used as the target power saving level, and the vehicle control strategy corresponding to the second level is executed, corresponding to the vehicle function state of the second level. In the above example, when the vehicle does not turn on the navigation, the corresponding vehicle control strategy is executed, which reduces the energy consumption of the vehicle and saves electricity.

[0087] Optionally, when the driver turns on navigation, after obtaining the vehicle's current cruising range and navigation distance, the device also includes: a fourth processing module, used to obtain the distance between the nearest charging pile and the current vehicle position; if the cruising range is not greater than the distance, the fourth level is used as the target power saving level; a calculation module 32, specifically used to: if the cruising range is greater than the distance, calculate the current mileage margin based on the current state parameters.

[0088] Specifically, when navigation is turned on, based on the current range and navigation distance of the vehicle, before calculating the current mileage margin, the distance between the current nearest charging post and the current vehicle position must be obtained. This distance is the distance of the current nearest available charging column identified by the vehicle navigation. If the obtained range is not greater than this distance, the fourth level is used as the target power saving level, and the corresponding vehicle control is performed; if the obtained range is greater than this distance, the current mileage margin is continued to be calculated, and the corresponding power saving level is obtained according to the mileage margin interval corresponding to the current mileage margin, and the corresponding vehicle control is performed. In the above example, when navigation is turned on, it is determined whether the range is greater than the distance between the current nearest charging post and the current vehicle position, and the vehicle is divided into power saving levels taking into account the convenience of energy replenishment, thereby saving electricity while meeting driving needs.

[0089] Specifically, the second processing module 33 is specifically used to: if the target power saving level is the first level, execute vehicle control according to the control strategy corresponding to the first level; the control strategy corresponding to the first level includes: the maximum speed is not limited, the energy recovery level is adjusted to the intermediate level; the automatic driving function is turned off, and other auxiliary driving functions except the automatic driving function are retained; the air conditioner is switched to ECO mode, the seat massage, heating and ventilation functions are turned off, and the cockpit expansion function is supported; and the application is supported;

[0090] If the target power saving level is the second level, the vehicle control is performed according to the control strategy corresponding to the second level; the control strategy corresponding to the second level includes: the maximum speed is limited to 120 km / h, the energy recovery level is adjusted to high level; the automatic driving function is turned off, and other auxiliary driving functions except collision warning, lane keeping and departure warning, parking assistance, driving recorder and emergency recording function are turned off; the air conditioner is switched to ECO mode, the seat massage, heating and ventilation functions are disabled, and the cabin expansion function is turned off; support the opening of applications;

[0091] If the target power saving level is the third level, the vehicle control is performed according to the control strategy corresponding to the third level; the control strategy corresponding to the third level includes: the maximum speed is limited to 100 km / h, the energy recovery level is adjusted to high level; the automatic driving function is turned off, and other auxiliary driving functions except collision warning, reversing radar, driving recorder and emergency recording function are turned off; the air conditioner is turned off, the seat massage, heating and ventilation functions are disabled, and the cockpit expansion function is disabled; the application is closed;

[0092] If the target power saving level is the fourth level, the vehicle control is performed according to the control strategy corresponding to the fourth level; the control strategy corresponding to the fourth level includes: the maximum speed is limited to 80 kilometers per hour, and the energy recovery level is adjusted to the highest level; the automatic driving function and other assisted driving functions are disabled; the air conditioning is disabled, the seat massage, heating, and ventilation functions are disabled, and the cabin expansion function is disabled; and the application is disabled.

[0093] Among them, each target power saving level can control the vehicle according to four aspects: power, intelligent driving, cockpit, and entertainment audio and video.

[0094] If the target power saving level is the first level, the vehicle control is performed according to the control strategy corresponding to the first level. In terms of power, the maximum vehicle speed is controlled without speed limit, the torque response is slowed down, and the energy recovery level is adjusted to the intermediate level; in terms of intelligent driving, the automatic driving function is turned off, and other auxiliary driving functions except the automatic driving function are retained; in terms of the cockpit, the air conditioner is switched to ECO mode, and the seat massage, heating, and ventilation functions are turned off. They can be turned on manually again, and the cockpit expansion function is supported; in terms of entertainment and audio-visual, it supports the opening of entertainment and audio-visual and third-party applications.

[0095] If the target power saving level is the second level, the vehicle control is performed according to the control strategy corresponding to the second level. In terms of power, the maximum speed is limited to 120 km / h, and kick-down is possible. The torque response becomes slower and the energy recovery level is adjusted to a high level. In terms of intelligent driving, the automatic driving function is turned off, as well as other auxiliary driving functions except collision warning, lane keeping and departure warning, parking assistance, driving recorder and emergency recording functions. In terms of the cockpit, the air conditioner is switched to ECO mode, and the seat massage, heating and ventilation functions are disabled and cannot be turned on manually again. The cockpit expansion function is turned off and can be turned on manually again. In terms of entertainment and audio-visual, the activation of entertainment and audio-visual and third-party applications is supported.

[0096] If the target power saving level is the third level, the vehicle control is performed according to the control strategy corresponding to the third level. In terms of power, the maximum speed is limited to 100 km / h, and kick-down is possible, the torque response becomes slower, and the energy recovery level is adjusted to a high level. In terms of intelligent driving, the automatic driving function is turned off, as well as other auxiliary driving functions except collision warning, reversing radar, driving recorder and emergency recording functions. In terms of the cockpit, the air conditioning is turned off, and can be turned on manually again and enters the ECO mode by default after being turned on. The seat massage, heating, and ventilation functions are disabled and cannot be turned on manually again. The cockpit expansion function is disabled and cannot be turned on manually again. In terms of entertainment and audio-visual, entertainment and audio-visual and third-party applications are turned off and can be turned on manually again.

[0097] If the target power saving level is the fourth level, the vehicle control is executed according to the control strategy corresponding to the fourth level. In terms of power, the maximum speed is limited to 80 km / h, and kick-down is possible, the torque response becomes slower, and the energy recovery level is adjusted to the highest level. In terms of intelligent driving, the automatic driving function and other assisted driving functions are disabled and cannot be manually turned on again, and all the hosts, controllers, and sensors related to intelligent driving are dormant. In terms of the cockpit, the air conditioning, seat massage, heating, and ventilation functions are disabled, and the cockpit expansion function is disabled and cannot be manually turned on again. In terms of entertainment and audio-visual, entertainment and audio-visual and third-party applications are disabled and cannot be manually turned on again.

[0098] Among them, energy recovery adjustment to intermediate, advanced, and highest levels means adjusting the gear of energy recovery adjustment on the vehicle to intermediate, advanced, and highest levels. The corresponding electric energy recovery amount may be different for different vehicles. The energy recovery gear can be adjusted according to the actual vehicle situation. The cockpit expansion function refers to other functions that can be realized in the cockpit, such as car refrigerators, car theaters, and car holographic images. Kick-down breakthrough means that when the vehicle needs to accelerate sharply or needs to increase the driving force quickly during driving, in order to quickly obtain sufficient acceleration power, the driver breaks through the current driving restrictions, presses the accelerator to the bottom and forces the car to downshift to get enough driving force.

[0099] Through the solution of this example, the vehicle's maximum speed, power response, energy recovery, air conditioning performance, assisted driving, entertainment and audio-visual, and vehicle expansion functions are optimized, turned off or disabled, and one-click operation is achieved to achieve the current best endurance and energy consumption. In addition, this solution can meet personalized driving needs.

[0100] In addition, taking into account the actual control of the vehicle, based on any of the aforementioned examples, the device also includes: a fifth processing module, which is used to detect whether the current moment and the previous moment are in the same driving cycle if the target power saving level determined this time is different from the target power saving level determined last time; wherein a single driving cycle represents the period from power-on to power-off of the vehicle; if they are in the same driving cycle, continue to control the vehicle according to the target power saving level determined last time; otherwise, control the vehicle according to the target power saving level determined this time.

[0101] Specifically, if the target power saving level determined this time is different from the target power saving level determined last time, it is necessary to detect whether the current moment is in the same driving cycle as the last moment. A single driving cycle refers to the period from when the vehicle is powered on and starts driving after the current target power saving level is determined until the vehicle is powered off at the end of driving. If the current moment is in the same driving cycle as the last moment, the corresponding vehicle control is performed according to the target power saving level determined last time; if the current moment is not in the same driving cycle as the last moment, the corresponding vehicle control is performed according to the target power saving level determined this time. In the above example, before the vehicle is powered on and starts driving, the target power saving level in this driving cycle is determined, and switching the target power saving level is not allowed in the same driving cycle. When a driving cycle is restarted, the target power saving level will be determined again to prevent unexpected risks caused by the jump of the target power saving level.

[0102] In the vehicle control device provided in this example, the first processing module detects whether the navigation function is in the on state. If the navigation is in the on state, the current state parameters are obtained, and the state parameters include the cruising range and the navigation distance; then the calculation module calculates the current mileage margin according to the current state parameters, and the mileage margin is the ratio of the cruising range to the navigation distance; the second processing module then uses the current mileage margin and the mileage margin interval corresponding to each power saving level as the target power saving level, and if the current ambient temperature exceeds the preset temperature range, the higher level of the target power saving level is used as the updated target power saving level, and the vehicle control is performed according to the target power saving level; wherein, the control strategies for different power saving levels are different, and the vehicle function states for different control strategies are different. In the scheme of the present application, when the navigation is turned on, the target power saving level is calculated by identifying the current remaining cruising range of the vehicle and the distance to the destination for navigation, and the final target power saving level is determined according to the current ambient temperature of the vehicle, so as to perform intelligent control on the vehicle. Under the condition of not affecting the user's driving experience as much as possible, some devices in the vehicle can be optimized, turned off or disabled with one click, so as to timely and flexibly adjust the vehicle's power consumption level in the scenario of electric vehicle intelligence, ensure the vehicle's range in the scenario of intelligent vehicle, and solve the problem of range anxiety. In addition, this solution can meet personalized driving needs.
