[0039] The embodiments of the present application will be described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0040] In this document, relational terms such as first and second and the like can be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus.

[0041] A control method, device, vehicle and storage medium for intelligent driving mode of a vehicle are described below with reference to the accompanying drawings. As mentioned in the background, the current switching of the driving mode of a vehicle is in a fixed manner. In particular, for a vehicle in a driving state, the switching from one driving mode to another driving mode needs to be performed manually, and cannot be intelligently switched according to the road conditions and the driving habits of the driver. The experience of the driver is not continuous enough. Based on this problem, the present application provides a control method for intelligent driving mode of a vehicle. After the intelligent mode is activated, the current driving mode is automatically switched to one of the preset driving modes through road condition information and / or torque demand, thereby overcoming the problem that the current vehicle switches the driving mode manually and the experience is not continuous enough.

[0042] Specifically, the present application provides a control method for intelligent driving mode of a vehicle, Figure 1 is a flowchart of the control method for intelligent driving mode of a vehicle provided by the present application.

[0043] As Figure 1 shown, the control method for intelligent driving mode of a vehicle comprises:

[0044] In step S100, after receiving an activation signal of the intelligent driving mode of the vehicle, the vehicle enters the intelligent driving mode;

[0045] In an embodiment, the driving mode of the vehicle is provided with an energy-saving mode, a comfortable mode, a sports mode and a catapult mode, and the vehicle is provided with an energy recovery level enhancement, an energy recovery level strength, an energy recovery level standard and an energy recovery level off. The energy recovery level matched with the energy-saving mode is enhancement, the energy recovery level matched with the comfortable mode is strength, the energy recovery level matched with the sports mode is standard, and the energy recovery level matched with the catapult mode is off. Wherein, the driving mode from the energy-saving mode, the comfortable mode, the sports mode to the catapult mode indicates that the user's driving torque demand is getting larger and larger and the power is getting more and more fierce under the same accelerator pedal opening, and the energy recovery level from enhancement, strength, standard to off indicates that the energy recovery level demand is getting smaller and smaller and the energy recovery is getting weaker and weaker (and the influence on acceleration is also getting smaller and smaller). If the activation signal of the intelligent driving mode of the vehicle is not received, the user can manually switch to the corresponding driving mode and match the corresponding energy recovery level.

[0046] In step S200, after the vehicle enters the intelligent driving mode, the speed of the vehicle is obtained, the speed is compared with a preset speed to obtain a comparison result, and the initial driving mode and the initial energy recovery level are determined according to the comparison result;

[0047] In some embodiments, determining the initial driving mode and the initial energy recovery level according to the comparison result comprises: if the vehicle speed is less than or equal to a first preset vehicle speed, the initial driving mode is an energy-saving mode and the initial energy recovery level is enhanced; if the vehicle speed is greater than the first preset vehicle speed and less than a second preset vehicle speed, the initial driving mode is a comfort mode and the initial energy recovery level is strong; and if the vehicle speed is greater than the second preset vehicle speed, the initial driving mode is a sport mode and the initial energy recovery level is standard. Specifically, the vehicle speed can be detected by a vehicle control unit (VCU) based on an ESC chassis speed.

[0048] In step S300, an operating parameter of the vehicle is acquired, a target driving mode of the vehicle is determined according to the operating parameter, and the vehicle is controlled to operate in the target driving mode;

[0049] Optionally, the operating parameter comprises a vehicle speed, a brake pedal depression frequency and an accelerator pedal opening degree change rate, and the target driving mode of the vehicle is determined according to the operating parameter by:

[0050] a first judgment condition is determined according to the vehicle speed and the brake pedal depression frequency;

[0051] a second judgment condition is determined according to the accelerator pedal opening degree change rate;

[0052] the target driving mode of the vehicle is determined according to the first judgment condition or the second judgment condition.

[0053] In some embodiments, the target driving mode comprises a first driving mode, a second driving mode and a third driving mode, and the preset vehicle speed comprises a first preset vehicle speed and a second preset vehicle speed.

[0054] Specifically, the first driving mode is an energy-saving mode, the second driving mode is a comfort mode, and the third driving mode is a sport mode.

[0055] The target driving mode of the vehicle is determined according to the first judgment condition or the second judgment condition by:

[0056] if the first judgment condition is that a duration that the vehicle speed is less than or equal to the first preset vehicle speed is greater than a first preset duration and the brake pedal depression frequency is greater than or equal to a first preset frequency, or the second judgment condition is that a duration that the accelerator pedal opening degree change rate is less than or equal to a first preset opening degree is greater than a second preset duration, the target driving mode is the first driving mode;

[0057] wherein the torque of the first driving mode is less than the torque of the second driving mode, the torque of the second driving mode is less than the torque of the third driving mode, and the first preset vehicle speed is less than the second preset vehicle speed.

[0058] Specifically, the first preset vehicle speed, the first preset time length, the first preset frequency, the first preset opening degree, the second preset vehicle speed, the second preset frequency, the second preset time length, the third preset frequency, and the second preset opening degree can be set according to user requirements, for example, the first preset vehicle speed includes but is not limited to 30 km / h, the first preset time length includes but is not limited to 15 s, the first preset frequency includes but is not limited to 10 times of user stepping on the brake pedal within 60 s, the first preset opening degree includes but is not limited to 30%, the first preset time length includes but is not limited to 5 s, the second preset vehicle speed includes but is not limited to 100 km / h, the second preset frequency includes but is not limited to 5 times of user stepping on the brake pedal within 60 s, the second preset time length includes but is not limited to 3 s, the third preset frequency includes but is not limited to 1 time of user stepping on the brake pedal within 60 s, and the second preset opening degree includes but is not limited to 50%.

[0059] Specifically, the lower the vehicle speed, the greater the frequency of stepping on the brake pedal, and the more serious the congestion degree of the road condition, so that the congestion degree of the road condition corresponding to the energy-saving mode is greater than that of the comfort mode, and the congestion degree of the road condition corresponding to the comfort mode is greater than that of the sports mode, so that the present scheme solves the problem that the driving mode of the vehicle cannot be intelligently switched according to the road condition; and the corresponding energy recovery level is matched through different driving modes to better utilize the vehicle energy, that is, the corresponding energy recovery mode is matched according to different road conditions, so as to reduce the vehicle energy consumption in the entire driving process.

[0060] For example, when the vehicle controller VCU detects that either of the following two conditions is met, the target driving mode matched by the vehicle controller VCU at this time is the energy-saving mode and the corresponding energy recovery level.

[0061] 1) The ESC chassis vehicle speed v is less than or equal to 30 km / h, and the vehicle speed duration Tv is greater than or equal to 15 s, and the number of times of user stepping on the brake pedal within 60 s is greater than or equal to 10 (congested road condition).

[0062] 2) The change rate A of the accelerator pedal is less than 30%, and the change rate of the maintained changed accelerator pedal opening degree is maintained for a duration Ta of 5 s or more.

[0063] A = (a2-a1) x 100%

[0064] A: Change rate of the accelerator pedal (the data sampling period frequency can be set according to user requirements, for example, the data sampling period frequency includes but is not limited to 100 ms);

[0065] a2: Accelerator pedal opening degree of the next period;

[0066] a1: Accelerator pedal opening degree of the current period;

[0067] Remark: The relationship between the accelerator pedal opening, vehicle speed and demand torque is obtained by real vehicle test method, which is a two-dimensional table conforming to the physical characteristics of the drive motor, as shown in Table 1:

[0068] Table 1: Two-dimensional table of physical characteristics of drive motor

[0069]

[0070] As the vehicle speed increases, the demand torque value gradually increases; as the accelerator pedal opening increases, the demand torque value gradually increases.

[0071] In some embodiments, optionally, the determining the target driving mode of the vehicle according to the first judgment condition or the second judgment condition further includes:

[0072] If the first judgment condition is that the vehicle speed is greater than a first preset vehicle speed and less than a second preset vehicle speed for a duration greater than a first preset duration, and the brake pedal depression frequency is less than a first preset frequency and greater than a second preset frequency, or the second judgment condition is that the accelerator pedal opening rate of change is greater than a first preset opening and less than or equal to a second opening for a duration greater than a second preset duration, then the target driving mode is the second driving mode.

[0073] For example, when the vehicle controller VCU detects that either of the following two conditions is true, then the target driving mode matched by the vehicle controller VCU is the comfort mode and the corresponding energy recovery level;

[0074] 1) ESC chassis speed 30km / h < V < 100km / h, and vehicle speed duration Tv ≥ 10s, the number of times the user steps on the brake pedal within 60s is greater than or equal to 5 and less than 10 (comfortable road conditions).

[0075] 2) The change rate of the accelerator pedal A is detected to be greater than [30%, 50%], and the maintained change rate of the accelerator pedal opening is maintained for a duration Ta of 3 seconds or more.

[0076] In some embodiments, the determining the target driving mode of the vehicle according to the first judgment condition or the second judgment condition further includes:

[0077] If the first judgment condition is that the vehicle speed is greater than or equal to the second preset vehicle speed for a duration greater than the first preset duration, and the brake pedal depression frequency is less than or equal to the second frequency and greater than a third preset frequency, or the second judgment condition is that the accelerator pedal opening rate of change is greater than the second preset opening for a duration greater than the second preset duration, then the target driving mode is the third driving mode.

[0078] Exemplarily, when the vehicle control unit VCU detects that either of the following two conditions is met, the target driving mode matched by the vehicle control unit VCU is the sport mode and the corresponding energy recovery level;

[0079] 1) ESC chassis speed 100km / h < V, and vehicle speed duration Tv≥5s, the number of times the user steps on the brake pedal within 60s is greater than or equal to 1 and less than 5 (smooth road conditions).

[0080] 2) The rate of change of the accelerator pedal A is detected to be greater than 50%, and the rate of change of the changed accelerator pedal opening is maintained for a duration Ta of 2 seconds or more.

[0081] Since each driving mode sets a torque value, and prevents torque from suddenly changing due to switching of the driving mode, which leads to poor smoothness and affects the user's driving experience. As the vehicle speed increases, the required torque value gradually increases; as the throttle pedal opening increases, the required torque value gradually increases, so the torque value set in the energy saving mode is less than the torque value set in the comfort mode, and the torque value set in the comfort mode is less than the torque value set in the sport mode. In some embodiments, the target driving mode of the vehicle is determined according to the operating parameters, and the vehicle is controlled to operate in the target driving mode further comprises:

[0082] Obtaining the current driving mode of the vehicle;

[0083] If the current driving mode is inconsistent with the target driving mode, when the vehicle is controlled to switch from the current driving mode to the target driving mode, the torque change value of the vehicle is limited according to the torque corresponding to the current driving mode and the torque corresponding to the target driving mode.

[0084] Exemplarily, the torque change value of the vehicle is limited by the following formula:

[0085] N = N X-1 + min[(N0-N X-1 ), (k*T)];

[0086] N: represents the actual output torque;

[0087] N X-1 : represents the torque value of the last period;

[0088] N0: represents the target torque value;

[0089] k: represents the current gradient value;

[0090] T: represents the current set period length;

[0091] The current gradient value k is determined by the target torque value and the difference ΔN of the last cycle torque; when ΔN is in the range of (-1000-0-1000), the range of k is (20000-0-20000).

[0092] In step S400, a matching state of the energy recovery level and the intelligent driving mode is obtained, a target energy recovery level is determined based on the target driving mode, the initial energy recovery level and the matching state, and the vehicle is controlled to operate in the target energy recovery level, wherein the matching state includes a following state and a non-following state.

[0093] Optionally, the determination of the target energy recovery level based on the target driving mode, the initial energy recovery level and the matching state includes:

[0094] If the matching state is the following state, the target energy recovery level is determined according to the target driving mode;

[0095] If the matching state is the non-following state, the target energy recovery level is determined as the initial energy recovery level.

[0096] Specifically, if the target driving mode is the energy saving mode, the target energy recovery level is enhanced; if the target driving mode is the comfort mode, the target energy recovery level is strong; and if the target driving mode is the sports mode, the target energy recovery level is standard.

[0097] In another embodiment, the present application provides a control device for intelligent driving mode of a vehicle, comprising:

[0098] An activation module 100 is configured to receive an activation signal of an intelligent driving mode of a vehicle, and the vehicle enters the intelligent driving mode after the activation signal is received;

[0099] An initial state determination module 200 is configured to obtain a vehicle speed of the vehicle after the vehicle enters the intelligent driving mode, compare the vehicle speed with a preset vehicle speed to obtain a comparison result, and determine an initial driving mode and an initial energy recovery level according to the comparison result;

[0100] A control module 300 is configured to obtain an operating parameter of the vehicle, determine a target driving mode of the vehicle according to the operating parameter, and control the vehicle to operate in the target driving mode; and

[0101] A matching module 400 is configured to obtain a matching state of an energy recovery level and an intelligent driving mode, determine a target energy recovery level based on the target driving mode, the initial energy recovery level and the matching state, and control the vehicle to operate in the target energy recovery level, wherein the matching state includes a following state and a non-following state.

[0102] The working principle of the vehicle intelligent driving mode control device is the same as the principle of the vehicle intelligent driving mode control method.

[0103] In an embodiment, the present application also provides a vehicle comprising the vehicle intelligent driving mode control device. After the intelligent mode is activated, the vehicle can automatically switch the driving mode according to the vehicle speed, the brake pedal depression frequency and the accelerator pedal opening rate change rate, and the driver's use demand is improved without manual switching.
