[0041] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0042] In the description of the present application, “plurality” means two or more than two, unless otherwise clearly and specifically defined.

[0043] Reference to an "embodiment" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0044] The present invention provides a driving prompt method, device and equipment based on the engine operating status, which are described below respectively.

[0045] See also Figure 1 , Figure 1 A flowchart of an embodiment of a driving prompt method based on an engine operating state provided by the present invention is provided. A specific embodiment of the present invention discloses a driving prompt method based on an engine operating state, comprising:

[0046] S101, collecting real-time engine operation data, and determining multiple engine operation states according to the real-time engine operation data;

[0047] S102, prompting the driver's driving behavior according to various engine operating states, and recording the number of driving behavior prompts;

[0048] S103, determining engine operation state time proportions of various engine operation states according to the real-time engine operation data;

[0049] S104: Prompt the driver's driving behavior according to the engine running state time ratio and the number of driving behavior prompts.

[0050] In the above embodiment, the real-time operating data of the vehicle engine can be collected through the equipment on the whole vehicle, and the parameters such as engine running time, engine speed, torque, etc. can be collected through the sensors on the vehicle, and the collected information can be sent to the engine's instrument system to evaluate and remind the driver's driving behavior.

[0051] The engine high efficiency zone refers to the engine speed and torque within a certain range where the engine can perform at a higher performance, which belongs to a two-dimensional plane interval. The engine high efficiency operating state refers to a special point in the high efficiency zone, indicating that the engine is in the best operating state at this time. Judging the engine operating state is to determine whether the engine is in the high efficiency zone and whether it is in an efficient operating state.

[0052] The present invention is not intended to prevent the driver from engaging in dangerous driving behavior, but rather to keep the engine in a better operating state. Therefore, after the engine operating state is determined, the driver may be prompted for the first time, and the content of the prompt is to evaluate the current state of the engine, so that the driver can make adjustments when the engine has not reached an efficient operating state.

[0053] Afterwards, the proportion of time in the engine's high-efficiency zone and the proportion of time in the efficient operating state will be calculated. The proportion of time in the engine's high-efficiency zone and the proportion of time in the efficient operating state reflect the time when the engine runs efficiently. This can prompt the driver whether he needs to adjust the vehicle speed to control the engine to be in an efficient operating state and to increase the proportion of time in the high-efficiency zone.

[0054] When the engine is not in an efficient operating state, the driver needs to be prompted to perform upshift and downshift operations to adjust the engine's operating state. At this time, the driver may need to be reminded multiple times to control the engine to reach an efficient operating state. Therefore, if the driver still does not adjust his driving behavior after multiple reminders, other prompts will be given to the driver.

[0055] Compared with the prior art, the present embodiment provides a driving prompt method based on the engine running state, the method comprising: collecting real-time engine running data, determining multiple engine running states according to the real-time engine running data; prompting the driver's driving behavior according to the multiple engine running states, and recording the number of driving behavior prompts; determining the engine running state time proportion of each of the engine running states according to the real-time engine running data; prompting the driver's driving behavior according to the engine running state time proportion and the number of driving behavior prompts. The present invention determines the engine running state through the collected real-time engine running data, and prompts the driving behavior for the first time according to the determined engine running state, so as to prompt the driver to control the engine to stay in the high-efficiency zone or high-efficiency running state, and then calculates the engine running state time proportion, and prompts the driving behavior for the second time according to the engine running state time proportion and the number of driving behavior prompts, so as to urge the driver to control the engine in the high-efficiency zone or high-efficiency running state as soon as possible, so as to keep the engine in the high-efficiency zone or high-efficiency running state by prompting the driver's driving behavior, and give full play to the performance of the engine.

[0056] See also Figure 2 , Figure 2 The present invention provides Figure 1 In some embodiments of the present invention, the driving behavior of the driver is prompted according to a plurality of engine operating states, and the number of driving behavior prompts is recorded, including:

[0057] S201, if the engine operation state is that the engine is in an efficient operation state, prompting that the driving behavior is good;

[0058] S202, if the engine operating state is that the engine is in the high-efficiency zone and is not in the high-efficiency operating state, prompting the driver to shift up or down according to a preset rule;

[0059] S203: If the engine operation status is that the engine is not in the high efficiency zone, a driving behavior deviation is prompted.

[0060] In the above embodiment, when it is found that the engine itself is in an efficient operating state, it means that the engine has reached the optimal operating state and does not need to be adjusted, thus prompting the driver that the driving behavior is good and the driver only needs to maintain the current driving habits.

[0061] When the engine operating state is that the engine is in the high-efficiency zone and is not in the high-efficiency operating state, the engine can be gradually adjusted to the high-efficiency operating state only by shifting gears. Therefore, at this time, it is necessary to judge the engine and prompt the driver to shift up or down, so as to regulate the driver's behavior and make the engine reach the high-efficiency operating state.

[0062] When the engine has not reached the high-efficiency zone, it means that the current driving behavior is not conducive to the operation of the engine. Therefore, the driver will be prompted that the current driving behavior is deviating, so that the driver can understand the current driving status in time and make adjustments, and gradually put the engine into an efficient operating state.

[0063] In some embodiments of the present invention, the real-time engine operation data includes the real-time engine speed; if the engine operation state is that the engine is in the high-efficiency zone and is not in the high-efficiency operation state, the driver is prompted to shift up or down according to a preset rule, including:

[0064] When the difference between the real-time engine speed and the target speed is continuously greater than a first preset speed threshold for more than a first preset time, and the gear is not at the highest gear, the driver is prompted to shift up and the number of prompts to shift up is recorded.

[0065] In the above embodiment, the difference between the real-time engine speed and the target speed is calculated and compared with the result of the first preset speed threshold. If the difference between the two is greater than the first preset speed threshold for more than the first preset time, and the engine gear is not in the highest gear, it means that the engine needs to be shifted up to adjust the engine to an efficient operating state. Therefore, the driver needs to be prompted to shift up, and each time the driver is reminded to shift up, the number of prompts to shift up accumulates.

[0066] It should be noted that, as a preferred embodiment, the first preset time can be set to 10 seconds. However, the first preset speed threshold and the first preset time in the present invention can also be set according to actual needs, and the present invention does not impose further restrictions on this.

[0067] In some embodiments of the present invention, if the engine operating state is that the engine is in the high efficiency zone and is not in the high efficiency operating state, prompting the driver to shift up or down according to a preset rule also includes:

[0068] When the difference between the real-time engine speed and the target speed is continuously less than the second preset speed threshold for more than a second preset time, and the gear is not in the lowest gear, the driver is prompted to downshift and the number of downshift prompts is recorded.

[0069] In the above embodiment, the difference between the real-time engine speed and the target speed is calculated and compared with the result of the second preset speed threshold. If the time during which the difference between the two is less than the second preset speed threshold exceeds the second preset time, and the engine gear is not in the lowest gear, it means that the engine needs to be downshifted in order to adjust the engine to an efficient operating state. Therefore, the driver needs to be prompted to downshift, and each time the driver is reminded to downshift, the number of downshift prompts is accumulated.

[0070] It should be noted that, as a preferred embodiment, the second preset time can be set to 10 seconds. However, the second preset speed threshold and the second preset time in the present invention can also be set according to actual needs, and the set second preset speed threshold and the second preset time can be the same as the first preset speed threshold and the first preset time. The present invention does not impose further restrictions on this.

[0071] In some embodiments of the present invention, the engine operating state time proportions of various engine operating states are determined based on the real-time engine operating data, including: calculating the high-efficiency zone time proportion and the high-efficiency operating state time proportion respectively based on the total engine operating time, the engine operating time in the high-efficiency zone, and the engine operating time in the high-efficiency operating state.

[0072] In the above embodiment, the engine is calculated after it starts running to determine the total engine running time, and after judging that the engine reaches the high-efficiency zone and the high-efficiency running state, the engine running time in the high-efficiency zone and the high-efficiency running state are recorded respectively, and then the engine's high-efficiency zone time ratio and high-efficiency running state time ratio are determined, which reflects the running state of the engine during the entire running process.

[0073] In some embodiments of the present invention, prompting the driver's driving behavior according to the engine running state time ratio and the number of driving behavior prompts includes:

[0074] When the time proportion in the high-efficiency zone is lower than a first preset percentage or the time proportion in the high-efficiency operation state is lower than a second preset percentage, prompting the driver to control the vehicle speed;

[0075] The driver's upshift and downshift behaviors are prompted based on the number of upshift and downshift prompts.

[0076] In the above embodiment, the first preset percentage and the second preset percentage can be set according to actual needs, and the present invention does not impose further restrictions on this. The relationship between the high-efficiency zone time ratio and the first preset percentage, and the high-efficiency running state time ratio and the second preset percentage is used to prompt the driver to increase the engine high-efficiency zone time ratio and the high-efficiency running state time ratio.

[0077] In some embodiments of the present invention, prompting the driver's upshifting and downshifting behaviors according to the prompting upshifting and downshifting times includes:

[0078] When the number of times the gear-up reminder is exceeded, the driver is reminded that the gear-up is not timely.

[0079] When the number of downshift reminders exceeds the preset number of downshift reminders, the driver is reminded that downshifting is not timely.

[0080] In the above embodiment, the preset number of upshift reminders and the preset number of downshift reminders can be set according to actual needs, and the present invention does not impose further restrictions on this.

[0081] Since it takes the first preset time or the second preset time to determine that the engine needs to change gears, it has reflected that the engine has not been in an efficient operating state for a period of time. Multiple reminders indicate that the engine has not been in an efficient operating state for a long time. Therefore, it can be judged that the driver's driving behavior is in a deviation state. At this time, if the number of upshift reminders exceeds the preset number of upshift reminders, it prompts the driver to upshift in time; if the number of downshift reminders exceeds the preset number of downshift reminders, it prompts the driver to downshift in time.

[0082] In order to better implement the driving prompt method based on the engine running state in the embodiment of the present invention, on the basis of the driving prompt method based on the engine running state, correspondingly, please refer to Figure 3 , Figure 3 This is a schematic diagram of the structure of an embodiment of a driving prompt device based on an engine operating state provided by the present invention.
