[0047] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are merely examples of devices consistent with some aspects of the present application as detailed in the appended claims.
[0048] The maximum vehicle speed control method, control system, storage medium and vehicle of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments and implementations can be combined with each other.
[0049] Figure 1 A flow chart of a maximum vehicle speed control method according to an embodiment of the present application is disclosed. Figure 1 As shown, a maximum vehicle speed control method according to an embodiment of the present application may include steps S11 to S14.
[0050] In step S11 , during the driving process of the vehicle, the current GPS positioning information and map data of the vehicle, the current accelerator pedal opening P and the current accelerator pedal opening change rate K are obtained.
[0051] In order to ensure the reliability of the data, the current accelerator pedal opening change rate K obtained can be the average value of the accelerator pedal opening change rate calculated within a predetermined number of consecutive predetermined time periods. For example, the accelerator pedal opening change rate is calculated once every time T0, and the average value of the accelerator pedal opening change rate calculated within N1 consecutive (for example, N1 ≥ 5) T0 time periods is calculated, and the average value of the accelerator pedal opening change rate is used as the current accelerator pedal opening change rate K.
[0052] In step S12, the current road section on which the vehicle is traveling may be determined based on the current GPS positioning information and map data acquired in step S11.
[0053] In step S13, it is determined whether the current road section on which the vehicle is traveling is in a speed-limited section. If the result of the determination is "yes", the process proceeds to step S14. Otherwise, the process proceeds to step S15, and the speed-limiting process described in this application is not performed.
[0054] The following is a classification of speed limits for various road types, and the corresponding reference relationships are shown in Table 1:
[0055] Table 1
[0056] Segment Type Country Road Urban roads Provincial Highway national highway Highway Speed limit classification Speed limit section Speed limit section Speed limit section Non-speed limit road Non-speed limit road
[0057] For example, when the current road section where the vehicle is traveling is in an urban road, since the urban road is a speed-limited section, it is necessary to perform the maximum vehicle speed control described in this application on the vehicle to limit the speed of the vehicle.
[0058] Of course, it can be understood that the above Table 1 is only shown as an illustrative example. However, the present application is not limited to this, and reasonable speed limit division can be performed according to the road section type and its actual road section conditions.
[0059] In step S14, when the current road section is in a speed-limited section, the current maximum speed V0 of the vehicle can be dynamically adjusted based on the current road section of the vehicle determined in step S12 and the current accelerator pedal opening P and the current accelerator pedal opening change rate K obtained in step S11 to limit the speed of the vehicle.
[0060] The maximum vehicle speed control method of the present application dynamically and adaptively adjusts the vehicle's current maximum vehicle speed V0 through the vehicle's real-time GPS positioning information and map data, the current accelerator pedal opening, and the current accelerator pedal opening change rate, thereby improving the safety of vehicle driving, reducing traffic accidents caused by misoperation, and also meeting the user's driving needs.
[0061] Figure 2 A flow chart of a maximum vehicle speed control method according to another embodiment of the present application is disclosed. Figure 2 As shown, in some embodiments, the maximum vehicle speed control method of the present application may further include step S16 and step S17.
[0062] In step S16, the current vehicle speed v of the vehicle is acquired.
[0063] In step S17 , the current state of the vehicle may be determined based on the current vehicle speed v acquired in step S16 .
[0064] Among them, step S14 of dynamically adjusting the current maximum speed V0 of the vehicle based on the current road section, the current accelerator pedal opening P and the current accelerator pedal opening change rate K to limit the speed of the vehicle may further include step S141 and step S142.
[0065] In step S141 , the set maximum vehicle speed VS corresponding to the current road section is obtained.
[0066] In some embodiments, the maximum speed of vehicles traveling in various sections can be counted in advance according to the big data platform. The maximum speed of vehicles traveling in general is usually less than or equal to the legal maximum speed limit of the corresponding section. For example, the maximum speed data of vehicles traveling in general under various sections such as rural roads, urban roads, provincial roads, national roads and expressways can be counted according to the big data platform. Then, different set maximum speeds VS under various road conditions can be determined based on the maximum speed of vehicles traveling in general under various road conditions.
[0067] In some embodiments, the current rotation speed of the wiper motor may be acquired, and then the first proportion PT1 for limiting the set maximum vehicle speed VS may be determined based on the current rotation speed of the wiper motor.
[0068] A corresponding relationship table between the speed of the wiper motor and the first proportion PT1 may be established in advance, such as shown in the following Table 2:
[0069] Table 2
[0070] Speed rpm Below 300 300~500 500~800 800~1100 …… The first accounted for PT1% 5% 10% 15% 20% ……
[0071] The speed of the wiper motor can indicate the severity of the environmental conditions to a certain extent. For example, when the speed of the wiper motor is higher, it may indicate a heavier rainfall. Therefore, in the above Table 2, the first proportion PT1 can increase with the increase of the speed of the wiper motor.
[0072] After the current speed of the wiper motor is obtained, the corresponding first proportion PT1 may be obtained by referring to the above Table 2 according to the current speed of the wiper motor.
[0073] Further, the current power value of the vehicle headlights may be acquired, and then the second proportion PT2 for limiting the set maximum vehicle speed VS may be determined based on the current power value of the headlights.
[0074] A corresponding relationship table between the power value of the vehicle headlight and the second proportion PT2 can be established in advance, such as shown in the following Table 3: Table 3
[0075] Power value w Less than 50,000 5W~10W 10W~15W 15W~20W …… The second largest share is PT2% 5% 10% 15% 20% ……
[0076] The power value of the vehicle headlights can indicate the severity of the environmental conditions to a certain extent. For example, when the vehicle headlights are brighter, the output power value of the headlights is greater, which may indicate that the environment is darker. Therefore, in the above Table 3, the second proportion PT2 can increase with the increase of the power value of the vehicle headlights.
[0077] After the current power value of the vehicle headlight is obtained, the corresponding second proportion PT2 may be obtained by referring to the above Table 3 according to the current power value of the vehicle headlight.
[0078] After the first proportion PT1 and the second proportion PT2 are obtained, the maximum vehicle speed VS may be dynamically adjusted and set based on the first proportion PT1 and the second proportion PT2.
[0079] The adjusted set maximum vehicle speed VS′ may be, for example, as shown below:
[0080] VS ′ =VS×(1-PT1-PT2)
[0081] Of course, in other embodiments, the maximum vehicle speed VS may also be dynamically adjusted and set based on the first proportion PT1 or the second proportion PT2.
[0082] Continue to refer to Figure 2 In step S142, the current maximum speed V0 of the vehicle can be determined based on the current state of the vehicle and the set maximum speed VS corresponding to the current road section obtained in step S141, and combined with the current accelerator pedal opening P and the current accelerator pedal opening change rate K to limit the vehicle's speed.
[0083] When the first proportion PT1 and / or the second proportion PT2 are obtained, the set maximum vehicle speed VS in step S142 may adopt the set maximum vehicle speed VS′ after adjustment.
[0084] Figure 3 A flow chart of a maximum vehicle speed control method according to another embodiment of the present application is disclosed. Figure 3 As shown, in step S301, the vehicle is driving. In step S302, is it determined whether the current road section has a speed limit? When the result of the determination is "no", the process proceeds to step S303. In step S303, the vehicle responds according to the preset normal accelerator pedal MAP, that is, the corresponding torque is output through the preset normal accelerator pedal MAP according to the current accelerator pedal opening P and the current vehicle speed v.
[0085] When the result of step S302 is "yes", the process proceeds to step S304. In step S304, it is determined whether the vehicle is in a stationary start state according to the current vehicle speed v, that is, it is determined whether the current vehicle speed v is lower than a predetermined vehicle speed threshold, such as 3 km / h. The predetermined vehicle speed threshold can be calibrated in advance.
[0086] When it is determined that the current vehicle speed v is lower than the predetermined vehicle speed threshold, ie, v<3 km / h, it is determined that the vehicle is in a stationary starting state, and the process enters step S305.
[0087] In step S305, it is determined whether the vehicle has a risk of accidentally stepping on the accelerator, that is, whether the current accelerator pedal opening P is greater than the first opening threshold P1, and whether the current accelerator pedal opening change rate K is greater than the first change rate threshold K1. If the result of the judgment is "yes", the process proceeds to step S306. Otherwise, the process proceeds to step S307.
[0088] In step S306, when the vehicle is in a stationary starting state, when the current accelerator pedal opening P is greater than the first opening threshold P1, and the current accelerator pedal opening change rate K is greater than the first change rate threshold K1, that is, P>P1 and K>K1, it is considered that there is a risk of mis-stepping on the accelerator pedal, then, it can respond according to the preset creeping accelerator pedal MAP, which has nothing to do with the current accelerator pedal opening P, that is, the corresponding torque is output through the preset creeping accelerator pedal MAP according to the current vehicle speed v. In addition, the preset maximum vehicle speed VS1 of the creeping is used as the current maximum vehicle speed V0 to limit the vehicle speed.
[0089] In step S307, when the conditions that the current accelerator pedal opening P is greater than the first opening threshold P1 and the current accelerator pedal opening change rate K is greater than the first change rate threshold K1 are not met, that is, P>P1 and K>K1 are not met, then the preset normal accelerator pedal MAP can be responded to, and the vehicle speed can be limited by setting the maximum vehicle speed VS as the current maximum vehicle speed V0.
[0090] When step S304 determines that the current vehicle speed v is not lower than the predetermined vehicle speed threshold, for example, v≥3 km / h, it is determined that the vehicle is in a normal driving state, and the process enters step S308.
[0091] In step S308, it is determined whether the accelerator pedal is deeply depressed, that is, whether the current accelerator pedal opening P is greater than the second opening threshold P2 (P>P2). When the result of the determination is "no", the process proceeds to step S309. When the result of the determination is "yes", the process proceeds to step S310.
[0092] In step S309, when the vehicle is in normal driving state, when the current accelerator pedal opening P is not greater than the second opening threshold P2, that is, P≤P2, the normal accelerator pedal MAP is responded to, and the vehicle speed is limited by setting the maximum vehicle speed VS as the current maximum vehicle speed V0.
[0093] In step S310, when the vehicle is in a normal driving state, when the current accelerator pedal opening P is greater than the second opening threshold P2 (P>P2), the magnitude of the current accelerator pedal opening change rate K is further determined.
[0094] When the change rate K of the current throttle pedal opening is greater than the second change rate threshold K2, i.e., K > K2, the process proceeds to step S311. In step S311, when the vehicle is in a normal driving state, when the current throttle pedal opening P is greater than the second opening threshold P2 and the change rate K of the current throttle pedal opening is greater than the second change rate threshold K2, i.e., P > P2 and K > K2, it is determined at this time that the vehicle has a risk of abnormal rapid acceleration. To reduce the accident risk, the torque corresponding to the throttle pedal is no longer responded to at this time, and the preset maximum creep speed VS1 is used as the current maximum speed V0 to limit the speed of the vehicle.
[0095] When the change rate K of the current throttle pedal opening is not greater than the second change rate threshold K2, i.e., K ≤ K2, the process proceeds to step S312. In step S312, when the current throttle pedal opening P is greater than the second opening threshold P2 but the change rate K of the current throttle pedal opening is not greater than the second change rate threshold K2, i.e., P > P2 and K ≤ K2, the vehicle speed is limited by using the set maximum speed VS as the current maximum speed V0.
[0096] In some embodiments, a third change rate threshold K3 can also be set. Among them, the third change rate threshold K3 is less than the second change rate threshold K2.
[0097] Then, step S312 can further include steps S313 and S314.
[0098] In step S313, when the current throttle pedal opening P is greater than the second opening threshold P2 and the change rate K of the current throttle pedal opening is less than the third change rate threshold K3, i.e., P > P2 and K < K3, it is determined at this time that the vehicle is in normal accelerating driving. Then, it can be responded according to the preset normal throttle pedal MAP, and the vehicle speed is limited by using the set maximum speed VS as the current maximum speed V0.
[0099] In step S314, when the current throttle pedal opening P is greater than the second opening threshold P2 and the change rate K of the current throttle pedal opening is between the second change rate threshold K2 and the third change rate threshold K3, it is determined at this time that the vehicle is slightly accelerating too fast. Then, it can be responded according to the preset normal throttle pedal MAP multiplied by a predetermined torque response percentage. At this time, the output torque corresponding to the throttle pedal is equal to the corresponding output torque obtained by looking up the normal throttle pedal MAP according to the current throttle pedal opening P and the current vehicle speed v and then multiplying by the predetermined torque response percentage, and the vehicle speed is limited by using the set maximum speed VS as the current maximum speed V0.
[0100] In some embodiments, a torque response percentage table may be pre-established, wherein the torque response percentage table may provide a corresponding torque response percentage based on the ratio of the accelerator pedal opening change rate to the third change rate threshold K3 and the vehicle speed. The higher the ratio of the accelerator pedal opening change rate to the third change rate threshold K3, the smaller the corresponding torque response percentage.
[0101] After obtaining the current accelerator pedal opening change rate K, we can further obtain the ratio of the current accelerator pedal opening change rate K to the third change rate threshold K3, that is, K / K3. Then, based on the ratio of the current accelerator pedal opening change rate K to the third change rate threshold K3 (K / K3) and the current vehicle speed v, we can refer to the torque response percentage table to get the corresponding predetermined torque response percentage.
[0102] The maximum vehicle speed control method of the present application can effectively solve the problem of vehicles generally speeding on urban roads and residential areas and accidentally stepping on the accelerator, resulting in excessive speed and thus causing major traffic accidents. It not only improves the safety of the vehicle, but also meets the driving needs of users.

The processor 401 can read the corresponding computer program from the non-volatile memory 405 into the memory 404 and then run it to implement the steps of the maximum vehicle speed control method as described above. Of course, in addition to the software implementation, the present application does not exclude other implementation methods, such as logic devices or a combination of software and hardware, etc., that is to say, the execution subject of the following processing flow is not limited to each logic unit, but can also be hardware or logic components.
