[0054] The embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be construed as being limited to the embodiments described herein. Instead, these embodiments are provided to provide a more thorough and complete understanding of the present application. It should be understood that the drawings and embodiments of the present application are only for exemplary purposes and are not intended to limit the scope of protection of the present application.

[0055] The term "including" and its variations used herein are open inclusions, i.e., "including but not limited to". The term "based on" means "based at least in part on". The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments". The relevant definitions of other terms will be given in the following description.

[0056] Most of the current intelligent energy management strategies for hybrid vehicles are based on navigation, radar, and cameras to obtain environmental information to guide control. To achieve better control methods, hybrid vehicles need to be equipped with the above hardware, resulting in higher vehicle costs. For vehicles with advanced intelligent driving functions, a large amount of environmental data is collected for intelligent driving, but the data can only be used by the vehicle itself and cannot contribute to the intelligent control of other hybrid vehicles. For ordinary traditional fuel vehicles, although there are no large number of sensing devices such as radar and cameras, they can share their own location information, accelerator pedal, brake pedal information, etc. for use by hybrid vehicles to optimize the control strategy of hybrid vehicles.

[0057] To this end, an embodiment of the present application provides a hybrid vehicle control method and related devices to help hybrid vehicles improve the fuel economy of the vehicle.

[0058] See also Figure 1 , Figure 1 A method flow chart of a hybrid vehicle control method provided in an embodiment of the present application, the method specifically comprises the following steps:

[0059] Step 101: Determine a target vehicle corresponding to a control vehicle, and obtain target driving information of the target vehicle through a vehicle communication system.

[0060] Wherein, the control vehicle is a hybrid vehicle, the target driving information at least includes the status of each pedal in the target vehicle, and the control vehicle and the target vehicle are both equipped with the vehicle communication system. Figure 2 , Figure 2 The schematic diagram of the vehicle communication system structure provided by the embodiment of the present application includes a signal transmitter / receiver, a hard line and a vehicle display terminal. The signal transmitter / receiver is connected to the vehicle display terminal through a hard line, and the received and sent related information is displayed through the vehicle display terminal. Figure 3 , Figure 3 The vehicle communication schematic diagram provided in the embodiment of the present application, the vehicle communication system also connects the controllers inside the vehicle, such as the vehicle control unit (VCU), the intelligent cockpit module (ICM) and the intelligent driving control module (Front View Camera Module, FVCM) through hard wires to obtain the status of each internal controller of the vehicle, and the controller inside the vehicle and the gateway, the gateway and the signal transmitter / receiver are also connected through hard wires. Figure 3As shown, between vehicle A and vehicle B installed with the vehicle communication system, the driving information of other vehicles can be uploaded to and obtained from the vehicle communication system through their respective signal transmitters / receivers, thereby realizing vehicle-to-vehicle communication.

[0061] The vehicle communication system is installed in the control vehicle and the target vehicle. The control vehicle and the target vehicle can share information based on the vehicle communication system. The control vehicle can obtain the target driving information of the target vehicle and then adjust its own energy management strategy according to the target driving information.

[0062] It should be noted that in the embodiments of the present application, the car equipped with the vehicle communication system can be an ordinary fuel car, or other types of cars such as smart driving cars, new energy cars, etc., and the embodiments of the present application do not make specific limitations on this; and all vehicles described in the embodiments of the present application are equipped with the vehicle communication system.

[0063] In a possible implementation, the above step 101 may be implemented as follows:

[0064] Step 11: obtaining vehicle position information within a preset range around the controlled vehicle through the vehicle communication system;

[0065] Step 12: According to the vehicle position information, a vehicle located in front of the control vehicle in the driving direction and closest to the control vehicle is determined as a target vehicle corresponding to the control vehicle;

[0066] Step 13: Acquire target driving information of the target vehicle through the vehicle communication system.

[0067] During the driving process of the controlled vehicle, the vehicle position information of other vehicles within a preset range around the controlled vehicle is collected in real time, and the real-time collected vehicle position information is sent to the controlled vehicle.

[0068] It should be noted that in the embodiment of the present application, the preset range around the controlled vehicle can be set according to actual needs. The preset range can be a circular area with the controlled vehicle as the center, or a strip area with the controlled vehicle's driving direction as the axis and no more than a certain distance from the front and rear of the controlled vehicle. The embodiment of the present application does not make any specific limitations on this.

[0069] According to the vehicle position information, the vehicle that is in front of the controlling vehicle in the driving direction and closest to the controlling vehicle is screened out. Because the driving state of the vehicle closest to the controlling vehicle has the most obvious influence on the driving state of the controlling vehicle under the current driving state of the controlling vehicle, the target vehicle is determined as the target vehicle corresponding to the controlling vehicle, and the target driving information of the target vehicle is obtained through the vehicle communication system. The energy management strategy of the controlling vehicle is adjusted based on the target driving information of the target vehicle.

[0070] Specifically, the above step 13 can be implemented in the following way:

[0071] Step 21: collecting the position information, vehicle speed information, accelerator pedal state information and brake pedal state information of the target vehicle, generating target driving information of the target vehicle, and uploading the target driving information to the vehicle communication system;

[0072] Step 22: According to the position information of the target vehicle, the target driving information of the target vehicle is obtained from the vehicle communication system.

[0073] Among them, the position information of the target vehicle can be obtained through the vehicle positioning system, the speed information can be obtained through the engine speed, and the accelerator pedal state information and the brake pedal state information can be obtained through sensors installed on the accelerator pedal and the brake pedal. Of course, the position information, speed information, accelerator pedal state information and brake pedal state information of the target vehicle can also be collected by other means, and the embodiments of the present application do not specifically limit this.

[0074] Based on the collected position information, vehicle speed information, accelerator pedal state information and brake pedal state information of the target vehicle, target driving information of the target vehicle is generated, and the target driving information is uploaded to the vehicle communication system, so that the target driving information of the target vehicle can be shared based on the vehicle communication system. After the target driving information is uploaded to the vehicle communication system, the control vehicle can search for the target driving information corresponding to the position information from the vehicle communication system based on the position information of the target vehicle to which it corresponds, thereby obtaining the target driving information of the target vehicle.

[0075] Step 102: Detecting a target vehicle distance between the control vehicle and the target vehicle, and when the target vehicle distance is less than a preset vehicle distance threshold, determining a pedal state of the target vehicle according to the target driving information.

[0076] The target distance between the control vehicle and the target vehicle ahead is detected by a sensor installed on the control vehicle body, and the target distance is compared with a preset distance threshold. The preset distance threshold is a safety distance threshold set for the control vehicle. When the target distance is less than the preset distance threshold, there is a risk of collision between the control vehicle and the target vehicle. Therefore, when the target distance is less than the preset distance threshold, the speed of the control vehicle needs to be adjusted.

[0077] In the embodiment of the present application, since vehicle communication systems are installed in both the control vehicle and the target vehicle, the speed of the control vehicle can be adjusted accordingly based on the target driving information of the target vehicle obtained through the vehicle communication system and the pedal state of the target vehicle included in the target driving information. For example, when the target vehicle is decelerating, the speed of the control vehicle needs to be reduced quickly to avoid a collision between the control vehicle and the target vehicle; when the target vehicle is accelerating, the speed of the control vehicle can be slowly reduced.

[0078] It should be noted that in the embodiment of the present application, the preset vehicle distance threshold can be a fixed value or a value adaptively adjusted according to the current vehicle speed of the controlled vehicle. The embodiment of the present application does not specifically limit the setting method and specific value of the preset vehicle distance threshold.

[0079] Of course, in the embodiment of the present application, the target vehicle distance can also be detected based on the position information of the target vehicle and the position information of the control vehicle, and other methods can also be used to detect the target vehicle distance, which is not specifically limited in the embodiment of the present application.

[0080] Step 103: If the accelerator pedal of the target vehicle is depressed, the coasting energy recovery intensity of the control vehicle is reduced.

[0081] Coasting energy recovery can convert part of the kinetic energy into electrical energy during the vehicle's coasting process. The higher the coasting energy recovery intensity, the faster the vehicle speed decreases, and the higher the proportion of kinetic energy converted into electrical energy; the lower the coasting energy recovery intensity, the slower the vehicle speed decreases, and the lower the proportion of kinetic energy converted into electrical energy.

[0082] When the target vehicle distance is less than the preset vehicle distance threshold, the state of the target vehicle's accelerator pedal can be obtained through the target driving information. When the accelerator pedal is pressed, the speed of the target vehicle gradually increases, and the distance between the control vehicle and the target vehicle will also gradually increase. At this time, the gliding energy recovery intensity of the control vehicle can be reduced.

[0083] Specifically, see Figure 4 , Figure 4A flow chart of coasting energy recovery intensity control provided by an embodiment of the present application. By detecting the state of the accelerator pedal of the target vehicle and the target vehicle distance between the target vehicle and the control vehicle, it is determined whether the accelerator pedal of the target vehicle is pressed and the target vehicle distance is less than a preset vehicle distance threshold. If yes, the coasting energy recovery intensity of the control vehicle is reduced; if no, the current coasting energy recovery intensity is maintained.

[0084] Step 104: If the brake pedal of the target vehicle is depressed, the coasting energy recovery intensity of the controlled vehicle is increased.

[0085] When the target vehicle distance is less than the preset vehicle distance threshold, the state of the target vehicle's brake pedal can be obtained through the target driving information. When the brake pedal is pressed, the speed of the target vehicle gradually decreases, and the distance between the control vehicle and the target vehicle will further decrease. At this time, in order to avoid a collision between the control vehicle and the target vehicle, it is necessary to increase the gliding energy recovery intensity of the control vehicle.

[0086] Specifically, see Figure 5 , Figure 5 A flow chart of coasting energy recovery intensity control provided by another embodiment of the present application. By detecting the state of the brake pedal of the target vehicle and the target vehicle distance between the target vehicle and the control vehicle, it is determined whether the brake pedal of the target vehicle is pressed and the target vehicle distance is less than a preset vehicle distance threshold. If yes, the coasting energy recovery intensity of the control vehicle is increased; if not, the current coasting energy recovery intensity is maintained.

[0087] Furthermore, after step 104, the following steps may also be included:

[0088] It is detected whether the target vehicle distance is less than a braking vehicle distance threshold, and if so, the brake pedal of the control vehicle is controlled to be depressed.

[0089] If the target vehicle distance is less than the preset vehicle distance threshold, after increasing the coasting energy recovery intensity of the controlled vehicle, the target vehicle distance between the controlled vehicle and the target vehicle is further reduced. At this time, it is detected whether the target vehicle distance is less than the braking vehicle distance threshold, and the braking vehicle distance threshold is less than the preset vehicle distance threshold. If the target vehicle distance is less than the braking vehicle distance threshold, the brake pedal of the controlled vehicle is controlled to be pressed down, so as to further ensure the safety of the controlled vehicle and the target vehicle and avoid collision between the controlled vehicle and the target vehicle.

[0090] In a possible implementation, the method further includes:

[0091] Step 31: Acquire reference position information and reference driving information corresponding to each reference vehicle in the target road section through the vehicle communication system;

[0092] Step 32: Acquire the road condition information of the target road section according to the reference position information and reference driving information corresponding to each reference vehicle, and calculate the corresponding congestion distance when the control vehicle reaches the target road section.

[0093] See also Figure 6 , Figure 6 A flow chart of a vehicle charging control strategy provided in an embodiment of the present application. According to the location information of the target section, vehicles corresponding to the location information of the target section are screened out from the vehicle communication system, and these vehicles are used as reference vehicles corresponding to the control vehicle passing through the target section. The reference location information and reference driving information corresponding to the reference vehicle are obtained through the vehicle communication system, and based on the reference location information and reference driving information, the road congestion of the target section is analyzed to generate the road condition information of the target section. The road condition information may include the actual current road condition information of the target section, and may also include the predicted road condition information when the control vehicle reaches the target section.

[0094] Specifically, when determining the current actual road condition information of the target section, the distribution density of the reference vehicles in the current target section can be calculated according to the reference position information, and the congestion situation of the current target section can be determined based on the distribution density of the reference vehicles. Alternatively, the speed of each reference vehicle in the target section can be calculated according to the reference driving information, and the congestion situation of the current target section can be determined based on the speed. For example, when the speed is much lower than the normal driving speed, it can be determined that the target section is currently congested.

[0095] After determining the traffic condition information of the target section, the congestion distance corresponding to when the controlled vehicle reaches the target section can be calculated based on the road congestion situation in the target section at that time. Specifically, the congestion distance can be calculated based on the average driving speed of all reference vehicles in the traffic condition information.

[0096] Step 33: judging, based on the current battery power of the controlled vehicle, whether the target battery power when the controlled vehicle reaches the target road section is lower than a preset power threshold;

[0097] Step 34: If yes, start the engine to charge the battery of the control vehicle.

[0098] The current battery power of the control vehicle is obtained, and the target battery power of the control vehicle when it reaches the target road section is estimated according to the location information, current battery power, current driving mode and other information of the control vehicle, and it is determined whether the target battery power is lower than a preset power threshold; wherein the preset power threshold is used to describe the power required when the control vehicle travels the congested distance in pure electric mode. In order to save the fuel consumed by the control vehicle in the target road section, it is expected that the control vehicle passes the congested distance corresponding to the target road section in pure electric mode; and if the target battery power is lower than the preset power threshold, it means that the control vehicle cannot travel through the congested distance corresponding to the target road section in pure electric mode, so it is necessary to start the engine to charge the battery of the control vehicle, so that the control vehicle has enough power to travel through the congested distance corresponding to the target road section, reduce the fuel consumption of the control vehicle within the congested distance, and improve the fuel economy of the control vehicle. If the control vehicle is in a high-speed driving state when the engine is charging the battery of the control vehicle, then the fuel economy of the control vehicle can be further improved at this time.

[0099] Furthermore, the method further comprises the following steps:

[0100] The target driving route of the controlled vehicle when driving on the target road section is planned according to the reference position information and reference driving information corresponding to each reference vehicle in the target road section.

[0101] Among them, the target driving route is used to indicate the corresponding lane information of the controlled vehicle when it is driving on the target section. When the controlled vehicle passes through the target section according to the target driving route, the driving speed is not lower than the speed threshold. At this time, the controlled vehicle can be driven at a driving speed not lower than the speed threshold.

[0102] In congested roads, long periods of low-speed driving and frequent acceleration and deceleration will significantly reduce the vehicle's fuel efficiency and significantly increase energy consumption, leading to energy waste. In order to improve the fuel economy of the controlled vehicle when passing through the target section, it is necessary to plan the target driving route of the controlled vehicle when driving in the target section based on the reference position information and reference driving information corresponding to each reference vehicle in the target section.

[0103] See also Figure 7 , Figure 7A schematic diagram of a target driving route provided for an embodiment of the present application. The reference position information corresponding to the reference vehicle includes lane information when the reference vehicle is driving in the target section. Thus, based on the reference position information and the reference driving information, a target driving route corresponding to the target section is planned for the control vehicle. The target driving route is used to guide the control vehicle to change to the corresponding lane when passing through the target section, so that the control vehicle can pass through the target section at a higher driving speed by changing lanes. In an embodiment of the present application, when the control vehicle passes through the target section according to the target driving route, the driving speed is not lower than the speed threshold, which is a speed critical value with higher fuel efficiency determined based on the driving information of the control vehicle itself; when the driving speed of the control vehicle in the target section is lower than the speed threshold, the fuel efficiency of the control vehicle is greatly reduced, the fuel economy is reduced, and the energy consumption is increased.

[0104] The embodiment of the present application plans the driving route of the controlled vehicle when passing through the target section according to the reference position information and reference driving information corresponding to each reference vehicle in the target section, so that the controlled vehicle can pass through the target section at a higher driving speed, thereby improving the fuel efficiency of the controlled vehicle, reducing energy consumption, and improving the energy utilization and fuel economy of the controlled vehicle.

[0105] An embodiment of the present application provides a hybrid vehicle control method, which determines a corresponding target vehicle for a control vehicle and obtains target driving information of the target vehicle through a vehicle communication system, wherein the control vehicle is a hybrid vehicle, the target driving information includes at least the status of each pedal in the target vehicle, and the control vehicle and the target vehicle are both equipped with a vehicle communication system; by detecting a target vehicle distance between the control vehicle and the target vehicle, when the target vehicle distance is less than a preset vehicle distance threshold, the pedal status of the target vehicle is determined according to the target driving information, and the coasting energy recovery intensity of the control vehicle is adjusted according to the pedal status; if the accelerator pedal of the target vehicle is pressed, the coasting energy recovery intensity of the control vehicle is reduced; if the brake pedal of the target vehicle is pressed, the coasting energy recovery intensity of the control vehicle is increased. Coasting energy recovery can convert the kinetic energy during the coasting process of the controlled vehicle after the accelerator pedal is released into electrical energy for storage. When the controlled vehicle is powered by a battery, the stored electrical energy can be used to drive the vehicle, saving the fuel required during the driving process of the controlled vehicle. It can be seen that the present application obtains the target driving information corresponding to the target vehicle through the vehicle communication system, and then adjusts the coasting energy recovery intensity of the controlled vehicle according to the target driving information, thereby improving the conversion ratio of kinetic energy into electrical energy during the driving process of the controlled vehicle, saving fuel consumption during the driving process of the controlled vehicle, and thus improving the fuel economy of the controlled vehicle.
