[0076] S103: Estimate the amount of electricity required for pure electric power according to the road section information to obtain the estimated total energy consumption of the entire pure electric driving.

[0077] S104: When the estimated total energy consumption of the entire pure electric driving is greater than the remaining power of the vehicle, the control mode of the vehicle controller is switched to the hybrid power control mode, so that the vehicle controller controls the target vehicle to perform hybrid power driving.

[0078] Please see Figure 2 , Figure 2 A system framework diagram of a driving mode control system is shown, and the driving mode control system applies the hybrid vehicle driving control method provided in this embodiment.

[0079] The screen host is used to provide the user with a switch to turn on the driving mode and to judge the current navigation information to decide whether to initiate a request to enter the driving mode; when the conditions for entering the mode are met, the screen host controller initiates a request to enter the engine self-identification start mode to the vehicle controller through a bus signal; after confirming to enter the mode, the screen host needs to send the navigation information to the vehicle controller through the bus as required;

[0080] The vehicle controller is responsible for responding to the request from the host controller to enter the engine self-identification start mode, and feeding back the current actual driving mode to the screen host for display; at the same time, it performs real-time calculations based on the navigation information sent by the screen host to control the engine start;

[0085] In this embodiment, the execution subject of the method may also be a smart device such as a smart phone, a tablet computer, etc., which is not limited in this embodiment.

[0086] It can be seen that the hybrid vehicle driving control method described in this embodiment can automatically switch the hybrid driving mode of the transmitter according to the navigation information, which significantly reduces fuel consumption and improves the driving experience.

[0087] Example 2

[0088] Please see Figure 3 , Figure 3 The flow chart of a hybrid electric vehicle driving control method provided in this embodiment is as follows. The hybrid electric vehicle driving control method includes:

[0089] S201. When the map navigation software of the target vehicle is turned on and is in a navigation state for a preset destination, and the network communication state of the screen host controller on the target vehicle is normal, it is determined that the vehicle controller of the target vehicle enters a self-identification engine start driving mode.

[0090] In this embodiment, the entry judgment of the engine self-identification start driving mode is mainly determined by the screen host controller.

[0091] Please see Figure 4 , Figure 4 An example diagram of a judgment process for self-identifying an engine start driving mode is shown.

[0092] In this embodiment, after determining to enter the self-identification engine start driving mode, the method obtains a request for entering the engine self-identification start driving mode issued by the screen host, and determines that the vehicle controller of the target vehicle enters the self-identification engine start driving mode.

[0093] S202: When the vehicle controller of the target vehicle enters the self-identification engine start driving mode, the current navigation information, real-time road condition information and the current remaining battery power of the target vehicle are obtained through the screen host controller of the target vehicle.

[0094] In this embodiment, after entering the engine self-identification start driving mode, the screen host needs to send navigation information to the vehicle controller in real time for working condition prediction and engine start control.

[0095] In this embodiment, the screen host has a networking function, can update the road condition information in real time, and send the road condition information to the vehicle controller.

[0096] In this embodiment, the real-time traffic information mainly includes road segmentation information of the entire journey divided into sections according to the navigation plan based on the starting point and the end point of the navigation.

[0097] S203: According to the current navigation information and the real-time traffic information, the entire journey is segmented according to the navigation plan to obtain road segmentation information.

[0098] In this embodiment, the road section segmentation information at least includes the road section number of each road section, the road section length corresponding to each road section number, and the big data average vehicle speed corresponding to each road section number.

[0099] In this embodiment, the road segmentation information at least includes the road segment number of each road segment, the road segment length L corresponding to each road segment number, and the road segment length L corresponding to each road segment number. n And the big data average vehicle speed V corresponding to each road section number n .

[0100] S204: Estimate the amount of electricity required for pure electric power according to the road section information to obtain the estimated total energy consumption for the entire pure electric driving.

[0101] S205: When the estimated total energy consumption of the entire pure electric driving is greater than the remaining power of the vehicle, the control mode of the vehicle controller is switched to the hybrid power control mode, so that the vehicle controller controls the target vehicle to perform hybrid power driving.

[0102] As an optional implementation, the method further includes:

[0103] When the estimated total energy consumption of the entire pure electric driving is not greater than the remaining power of the vehicle, the control mode of the vehicle controller is switched to the pure electric control mode, so that the vehicle controller controls the target vehicle to perform pure electric driving.

[0104] S206: Obtain a pre-calibrated optimal vehicle speed for starting the engine.

[0105] In this embodiment, in order to obtain the best economy, the method can select the optimal engine starting speed V according to the energy consumption characteristics of the vehicle pure electric and HEV. on Among them, the vehicle speed is mainly calibrated based on the experimental energy consumption data of the whole vehicle. Since pure electric is more economical in low-speed driving in HEV mode, but engine direct drive has better economy in high-speed driving, after analyzing the experimental data, the optimal engine start speed V is calibrated to change from pure electric economy higher than engine direct drive economy to pure electric economy lower than engine direct drive economy. on .

[0106] S207. Calculate the estimated energy consumption required for each road section when driving entirely on pure electric power, based on the road section length and the average vehicle speed from the big data.

[0107] In this embodiment, the method can calculate the estimated energy consumption Q of each section of the road based on the navigation data. i :

[0108]

[0109] Among them, i represents the serial number of each road segment, V i represents the average speed of the i-th section of road, L i Represents the length of the i-th road segment.

[0110] In this embodiment, the vehicle controller stores average energy consumption test data of the vehicle running on pure electric power at various vehicle speeds (ie, map(*), which is obtained through vehicle testing and then stored in the vehicle controller).

[0111] S208. Determine a road section where the average vehicle speed of the big data is less than the optimal vehicle speed for starting the engine as a road section suitable for pure electric driving; determine a road section where the average vehicle speed of the big data is not less than the optimal vehicle speed for starting the engine as a road section suitable for hybrid driving.

[0112] In this embodiment, the method can be based on the optimal vehicle speed V on and the average speed of each section of road, V i Lower than V on The road sections are classified as sections suitable for pure electric driving, and the energy consumption of all pure electric sections is accumulated and calculated to obtain the energy consumption Q of the pure electric section. EV .

[0113] Among them, when Q EV Less than the remaining power consumption of the vehicle Q batt , it is judged that the remaining power can support all low-speed sections; when Q EV Greater than the remaining power consumption of the vehicle Q batt , it is judged that the remaining power cannot support driving on all low-speed sections, and it is necessary to select a suitable low-speed pure circuit section to start the engine for HEV driving.

[0114] In this embodiment, in order to ensure better economy, the method mainly selects a road section with a higher average vehicle speed in a pure circuit section for HEV driving.

[0115] S209: Determine the pure electric driving energy consumption corresponding to the pure electric driving section according to the estimated energy consumption.

[0116] In this embodiment, the calculation formula for the estimated energy consumption of pure electric driving in the entire road section (i.e., the energy consumption of the pure electric section) is:

[0117]

[0118] Among them, i represents the serial number of each road segment, V i represents the average speed of the i-th section of road, L i Represents the length of the i-th road segment.

[0119] S210, cumulatively calculating the pure electric driving energy consumption, and obtaining the estimated total pure electric driving energy consumption in the hybrid mode.

[0120] In this embodiment, after entering the engine self-identification start driving mode, the method estimates the energy consumption required for EV driving on the entire road section based on the navigation information of the host.

[0121] For example, this method first looks up the table to obtain the average power consumption per 100 kilometers of each section of road, then calculates the total estimated energy consumption of each section of road, and then adds up the energy consumption of all sections to obtain the estimated energy consumption of the entire section of road.

[0122] In this embodiment, the method compares the estimated total EV driving energy consumption with the remaining power of the vehicle. When the estimated energy consumption is greater than the remaining power of the vehicle, it is determined to enter the HEV module, and the module will automatically make an engine start judgment; when the estimated energy consumption is less than the remaining power of the vehicle, it is determined to maintain EV mode throughout the journey, and the module maintains the engine shutdown command throughout the journey.

[0123] Please see Figure 5 , Figure 5 An example diagram of a hybrid power control mode switching control logic is shown.

[0124] S211: When the estimated total energy consumption of pure electric driving in hybrid mode is not greater than the remaining power of the vehicle, hybrid driving control is performed on the target vehicle based on the optimal vehicle speed for engine start and the average vehicle speed of big data.

[0125] S212. When the estimated total energy consumption of pure electric driving in hybrid mode is greater than the remaining power of the vehicle, the sections suitable for pure electric driving are sorted in descending order according to the big data average vehicle speed of each section suitable for pure electric driving to obtain a sorting sequence of sections suitable for pure electric driving.

[0126] S213, sequentially remove the road sections suitable for pure electric driving corresponding to the maximum big data average vehicle speed from the sorting sequence of road sections suitable for pure electric driving, until the estimated total energy consumption of partial pure electric driving corresponding to the newly obtained sorting sequence of road sections suitable for pure electric driving is less than the remaining power of the whole vehicle.

[0127] S214: Based on the newly obtained sorting sequence of road sections suitable for pure electric driving, the target vehicle is controlled to drive in hybrid power.

[0128] Please see Figure 6 , Figure 6 Another example diagram of the hybrid power control mode switching control logic is shown. In which, when it is determined that the remaining power cannot cover the energy consumption required by the pure circuit section, the engine needs to be started in some pure circuit sections.

[0129] In this embodiment, the basic principle of the control logic is to drive the engine at a higher speed in the pure electric section. Based on this, the method needs to sort the average speeds of all pure electric sections and plan the pure electric section for starting the engine according to the average speed. On the other hand, for the pure electric section for starting the engine, there may be a situation where the engine does not need to be driven directly on the entire section. In this case, pure electric driving needs to be prioritized in this section.

[0130] As an optional implementation, the method further includes:

[0131] In the hybrid driving section where the target vehicle is subjected to hybrid driving control, it is calculated in real time whether the remaining power of the vehicle is sufficient to support all subsequent sections suitable for pure electric driving;

[0132] When the remaining power of the vehicle is sufficient to support all subsequent sections suitable for pure electric driving, the engine is shut down and the target vehicle is controlled to drive purely electric.

[0133] Please see Figure 7 , Figure 7 An example diagram of real-time engine self-identification control logic is shown.

[0134] Please see Figure 8 , Figure 8 A schematic diagram of a software architecture for a hybrid electric vehicle driving control method is shown.

[0135] In this embodiment, the execution subject of the method may be a computing device such as a computer or a server, and no limitation is made in this embodiment.

[0136] In this embodiment, the execution subject of the method may also be a smart device such as a smart phone, a tablet computer, etc., which is not limited in this embodiment.
