[0002] When the vehicle is driving, the driver often releases the accelerator to let the vehicle glide forward by inertia.

[0046] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] It should be noted that the terms "including" and "having" and their variations involved in the documents of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0048] The application scenarios described in the embodiments of the present disclosure are intended to more clearly illustrate the technical solutions of the embodiments of the present disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. It is known to those skilled in the art that with the emergence of new application scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems. In the description of the present disclosure, unless otherwise specified, the meaning of "multiple" is two or more.

[0049] The word "exemplary" used hereinafter means "used as an example, embodiment or illustrative". Any embodiment described as "exemplary" is not necessarily to be interpreted as being superior or better than other embodiments. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application, and the embodiments and features in the embodiments in the present application can be combined with each other if there is no conflict.

[0050] Some technical terms involved in this application are explained below.

[0051] 1) ADAS (Advanced Driver Assistance Systems): It is a special map designed to assist advanced driving. It has higher accuracy and more information than traditional maps, including detailed information such as road type, slope, curves, intersections, roundabouts, etc., which can help vehicles to accurately navigate and plan routes.

[0052] 2) GPS (Global Positioning System): It is a satellite-based navigation system used to determine the latitude, longitude, speed and time information of any location on the earth. GPS is a widely used positioning system in the world, providing positioning information in all weather and all day, with global coverage.

[0053] 3) Neutral gliding: This means that while the car is driving, the gear position of the car is switched to neutral, that is, no gear is engaged, and then the car relies on inertia to glide.

[0054] 4) Coasting with gear: This means that the car remains in a certain gear during driving, such as a low gear or high gear other than neutral, and coasts using the engine's inertia and braking effect.

[0055] When the vehicle is driving, the driver often releases the accelerator to let the vehicle glide forward by inertia. There are two types of glide, namely, glide with gear and glide with neutral gear. Research data shows that when gliding over long distances, glide with neutral gear saves more energy than glide with gear, while when gliding over short distances, glide with gear saves more energy than glide with neutral gear.

[0056] However, the vehicles in the related art are only set with a single gliding mode when leaving the factory, that is, after the driver releases the accelerator, the vehicle can only glide with gear or glide in neutral when sliding forward by inertia, which cannot maximize energy saving.

[0057] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0058] FIG1(a) and FIG1(b) show an application scenario of a vehicle driving control method provided by an embodiment of the present application, referring to FIG1(a) and FIG1(b), wherein FIG1(a) may be a scenario in which a vehicle responds to a user-triggered accelerator release operation at a ramp or a highway exit, and FIG1(b) may be a scenario in which a vehicle responds to a user-triggered accelerator release operation at an intersection. In the prior art, after responding to a user-triggered accelerator release operation, a vehicle can only glide with a gear or glide in neutral, and it is impossible to maximize energy saving.

[0059] To solve this problem, an embodiment of the present application provides a vehicle driving control method. After responding to a throttle release operation, the present application controls the vehicle's driving mode to coasting with a gear or coasting in neutral based on whether there is a road intersection, and based on the judgment conditions of the vehicle's driving direction, throttle opening information and vehicle speed information, so that the vehicle can choose to coast with a gear or coast in neutral based on the road conditions, thereby maximizing energy saving.

[0060] It should be noted that the application scenarios of Figures 1(a) and 1(b) are only examples of application scenarios for implementing the embodiments of the present application, and the embodiments of the present application are not limited to the application scenarios described in the above Figures 1(a) and 1(b).

[0061] Based on the application scenarios shown in FIG. 1(a) and FIG. 1(b) and the contents of the above related technical introduction, a vehicle driving control method is provided in an embodiment of the present application. Figure 2 The following is a schematic diagram showing a possible flow chart of a vehicle driving control method provided by an embodiment of the present application. Figure 2 As shown, the method includes:

[0062] S201, responding to a throttle release operation triggered by a user;

[0063] S202, when it is determined that there is a road intersection and the distance between the vehicle and the road intersection is less than a preset distance, based on the vehicle's driving direction, throttle opening information and vehicle speed information, controlling the vehicle's driving mode to be coasting with gear or coasting in neutral;

[0064] In a possible implementation, if it is determined that the vehicle is turning right, the throttle opening information is 0, and the vehicle speed information is greater than a preset speed, the vehicle is controlled to coast with gear; or, if it is determined that the vehicle is turning left, the throttle opening information is 0, and the vehicle speed information is greater than a preset speed, the vehicle is controlled to coast with gear.

[0065] Furthermore, the vehicle's driving direction, throttle opening information and vehicle speed information are obtained based on the Tbox (Telematics Box) inside the vehicle, wherein the Tbox can receive data from vehicle sensors (such as radars and cameras). In a specific embodiment, the vehicle's driving direction can be right turn driving, left turn driving and straight driving, the throttle opening information is usually expressed in percentage, 0% means completely closed, 100% means completely open, and the vehicle speed information is usually real-time data of the vehicle's forward movement during driving, usually expressed in kilometers per hour (km / h).

[0066] For example, the preset speed is 25km / h and the preset distance is 50m. For example, after it is determined that there is a road intersection and the distance between the vehicle and the road intersection is less than 50m, if it is determined that the vehicle's driving direction is a right turn, the throttle opening information is 0, and the vehicle speed information is 30km / h, that is, the preset conditions of determining that the vehicle's driving direction is a right turn, the throttle opening information is 0, and the vehicle speed information is greater than the preset speed are met, and the vehicle's driving mode is controlled to be coasting with gear.

[0067] For example, after determining that there is a road intersection and the distance between the vehicle and the road intersection is less than 50m, if it is determined that the vehicle's driving direction is a left turn, the throttle opening information is 0, and the vehicle speed information is 42km / h, that is, the preset conditions of determining that the vehicle's driving direction is a left turn, the throttle opening information is 0, and the vehicle speed information is greater than the preset speed are met, the vehicle's driving mode is controlled to coast with gear engaged.

[0068] In another possible implementation, the vehicle's driving direction is determined to be straight, or the throttle opening information is determined to be not 0, or the vehicle speed information is determined to be less than or equal to a preset speed, and the vehicle's driving mode is controlled to be neutral coasting.

[0069] For example, the preset speed is 25km / h and the preset distance is 50m. For example, after determining that there is a road intersection and the distance between the vehicle and the road intersection is less than 50m, if the vehicle's driving direction is determined to be straight, the throttle opening information is 0, and the vehicle speed information is 42km / h, the preset condition of determining that the vehicle's driving direction is straight is met, and the vehicle's driving mode is controlled to be neutral coasting.

[0070] For example, after determining that there is a road intersection and the distance between the vehicle and the road intersection is less than 50m, if it is determined that the vehicle's driving direction is to turn left, the throttle opening information is 20%, and the vehicle speed information is 30km / h, that is, the preset condition of determining that the throttle opening information is not 0 is met, the vehicle's driving mode is controlled to be neutral gliding.

[0071] For example, after determining that there is a road intersection and the distance between the vehicle and the road intersection is less than 50m, if it is determined that the vehicle's driving direction is to turn left, the throttle opening information is 0, and the vehicle speed information is 15km / h, that is, the preset condition of determining that the vehicle speed information is less than or equal to the preset speed is met, the vehicle's driving mode is controlled to be neutral gliding.

[0072] For example, after determining that there is a road intersection and the distance between the vehicle and the road intersection is less than 50m, if it is determined that the vehicle's driving direction is straight, the throttle opening information is 0, and the vehicle speed information is 15km / h, that is, the preset conditions of determining that the vehicle's driving direction is straight and determining that the vehicle speed information is less than or equal to the preset speed are met, the vehicle's driving mode is controlled to be neutral gliding.

[0073] That is to say, after determining that there is a road intersection and the distance between the vehicle and the road intersection is less than 50m, if any one of the preset conditions of determining that the vehicle's driving direction is straight, determining that the throttle opening information is not 0, and determining that the vehicle speed information is less than or equal to the preset speed is met, the vehicle's driving mode is controlled to coast in neutral.

[0074] S203, when it is determined that there is a road intersection and the distance between the vehicle and the road intersection is greater than or equal to a preset distance, or when it is determined that there is no road intersection, controlling the vehicle to coast in neutral;

[0075] For example, when it is determined that there is a road intersection, the preset distance is 50m. For example, if it is determined that there is a road intersection, the distance between the vehicle and the road intersection is 60m, that is, it is determined that the distance between the vehicle and the road intersection is greater than or equal to the preset distance, in response to the accelerator release operation triggered by the user, the driving mode of the vehicle is controlled to be neutral coasting.

[0076] Exemplarily, when it is determined that there is no road intersection, in response to a user-triggered accelerator release operation, the vehicle's driving mode is controlled to coast in neutral.

[0077] Among them, road intersections are determined based on the advanced driver assistance system ADAS map information and the global positioning system GPS positioning information.

[0078] The embodiment of the present application provides a vehicle driving control method, which responds to the accelerator release operation triggered by the user; when it is determined that there is a road intersection and the distance between the vehicle and the road intersection is less than a preset distance, based on the vehicle's driving direction, throttle opening information and vehicle speed information, the vehicle's driving mode is controlled to be coasting with a gear or coasting in neutral; when it is determined that there is a road intersection and the distance between the vehicle and the road intersection is greater than or equal to the preset distance, or when it is determined that there is no road intersection, the vehicle's driving mode is controlled to be coasting in neutral; wherein the road intersection is determined based on the advanced driver assistance system ADAS map information and the global system positioning GPS positioning information. That is to say, after responding to the accelerator release operation, the present application controls the vehicle's driving mode to coasting with a gear or coasting in neutral based on whether there is a road intersection and based on the judgment conditions of the vehicle's driving direction, throttle opening information and vehicle speed information, so that the vehicle can choose coasting with a gear or coasting in neutral based on the road conditions to maximize energy saving.

[0079] It should be noted that after determining that the vehicle's driving mode is coasting with gear or coasting in neutral, the operation of controlling the vehicle's driving mode is performed based on the AMT (Automated Manual Transmission) transmission.

[0080] In a possible implementation, Figure 3 FIG. 1 is a flow chart of a method for determining a road intersection provided in an embodiment of the present application. Based on ADAS map information and GPS positioning information, the road intersection is determined through the following steps:

[0081] S301, determining the current position of the vehicle based on GPS positioning information;

[0082] S302, based on the ADAS map information, obtaining road information of the driving section where the vehicle is currently located;

[0083] S303, in the driving direction of the vehicle, taking the current position of the vehicle as the starting point, selecting target road information within a preset range from the road information;

[0084] S304: Determine whether there is a road intersection based on the target road information.

[0085] In a specific embodiment, the current position of the vehicle is determined based on the GPS positioning information, and the road information of the driving section of the vehicle's current position is obtained based on the ADAS map information. The road information may include information such as traffic signs, signal lights, and road intersections. It should be noted that the road intersections in this application include intersection scenes such as ramps and crossroads.

[0086] Exemplarily, for example, the preset range is 2km. Then in the driving direction of the vehicle, with the current position of the vehicle as the starting point, based on selecting 2km of road information from the ADAS map information, the selected 2km of road information is used as the target road information. If there is a road intersection in the target road information, it is determined whether there is a road intersection. If there is no road intersection in the target road information, it is determined that there is no road intersection.

[0087] In a possible implementation, it also includes: after determining that the vehicle's driving mode is coasting with a gear, sending a reminder message indicating coasting with a gear to the instrument display panel; after determining that the vehicle's driving mode is coasting with a neutral gear, sending a reminder message indicating coasting with a neutral gear to the instrument display panel.

[0088] In a specific embodiment, if the current vehicle is a manual transmission vehicle, after determining the vehicle's driving mode, it is also necessary to send a reminder message indicating the vehicle's driving mode to the instrument display panel, so that the user can manually control the vehicle's driving mode based on the reminder message. For example, after determining that the vehicle's driving mode is coasting with gear, a reminder message of "coasting with gear" is sent to the instrument display panel, and the user manually controls the coasting with gear. After determining that the vehicle's driving mode is coasting in neutral, a reminder message of "coasting in neutral" is sent to the instrument display panel, and the user manually controls the coasting in neutral.

[0089] Furthermore, in order to better introduce the embodiments of the present application, Figure 4 FIG. 1 is a complete flow chart of a vehicle driving control method provided in an embodiment of the present application, comprising the following steps:

[0090] S401, responding to a throttle release operation triggered by a user;

[0091] S402, determining whether there is a road intersection based on the ADAS map information and the GPS positioning information, if yes, executing S403, otherwise, executing S404;

[0092] S403, determining whether the distance between the vehicle and the road intersection is less than a preset distance, if so, executing S405, otherwise, executing S404;

[0093] S404, controlling the vehicle to travel in a neutral gear sliding mode;

[0094] S405, determining whether the vehicle's driving direction is a right turn, the throttle opening information is 0, and the vehicle speed information is greater than a preset speed, if so, executing S406, otherwise, executing S407;

[0095] S406, controlling the vehicle to travel in a gear-geared manner;

[0096] S407, determine whether the vehicle's driving direction is a left turn, the throttle opening information is 0, and the vehicle speed information is greater than a preset speed. If so, execute S406, otherwise, execute S404.

[0097] Based on the same inventive concept, the embodiment of the present application also provides a vehicle driving control device, which has similar principles to the above-mentioned vehicle driving control method, and the repeated parts will not be repeated.

[0098] An operation response module 501 is used to respond to a throttle release operation triggered by a user;

[0099] The driving decision module 502 is used to control the driving mode of the vehicle to coasting with gear or coasting in neutral gear based on the driving direction, throttle opening information and vehicle speed information when it is determined that there is a road intersection and the distance between the vehicle and the road intersection is less than a preset distance; when it is determined that there is a road intersection and the distance between the vehicle and the road intersection is greater than or equal to the preset distance, or when it is determined that there is no road intersection, control the driving mode of the vehicle to coasting in neutral gear; wherein the road intersection is determined based on advanced driving assistance system ADAS map information and global positioning system GPS positioning information.

[0100] The embodiment of the present application provides a vehicle driving control method and device, which responds to the accelerator release operation triggered by the user; when it is determined that there is a road intersection and the distance between the vehicle and the road intersection is less than a preset distance, based on the vehicle's driving direction, throttle opening information and vehicle speed information, the vehicle's driving mode is controlled to be coasting with a gear or coasting in neutral; when it is determined that there is a road intersection and the distance between the vehicle and the road intersection is greater than or equal to the preset distance, or when it is determined that there is no road intersection, the vehicle's driving mode is controlled to be coasting in neutral; wherein the road intersection is determined based on the advanced driver assistance system ADAS map information and the global system positioning GPS positioning information. That is to say, after responding to the accelerator release operation, the present application controls the vehicle's driving mode to coasting with a gear or coasting in neutral based on whether there is a road intersection and based on the judgment conditions of the vehicle's driving direction, throttle opening information and vehicle speed information, so that the vehicle can choose coasting with a gear or coasting in neutral based on the road conditions to maximize energy saving.

[0105] Based on the target road information, it is determined that the road intersection exists.

[0106] In a possible implementation, the driving decision module 502 is specifically configured to:

[0108] Determine that the driving direction of the vehicle is turning left, the throttle opening information is 0, and the vehicle speed information is greater than a preset speed, and control the driving mode of the vehicle to coast with gear engaged.

[0109] In a possible implementation, the driving decision module 502 is specifically configured to:

[0110] Determine that the driving direction of the vehicle is straight, or determine that the throttle opening information is not 0, or determine that the vehicle speed information is less than or equal to a preset speed, and control the driving mode of the vehicle to the neutral coasting.

[0111] In a possible implementation, a reminder module 503 is further included, and the reminder module 503 is used to:

[0112] After determining that the driving mode of the vehicle is the gear-engaged coasting, sending a reminder message indicating the gear-engaged coasting to an instrument display panel;

[0113] After determining that the driving mode of the vehicle is the neutral coasting, a reminder message indicating the neutral coasting is sent to the instrument display panel.
