As described above, how to intelligently plan and control the electric quantity and the oil quantity of the vehicle during the traveling process becomes an important research problem.

Based on the above description, as shown in fig. 1, the vehicle control method proposed in the present embodiment is applied to a vehicle end, and is applicable to a hybrid vehicle. The method comprises the following steps:

and 101, acquiring the residual electric quantity of the battery and/or the residual oil quantity of the oil tank.

In specific implementation, the residual electric quantity of the battery is the current residual electric quantity of the vehicle battery pack, and the residual oil quantity of the oil tank is the current residual oil quantity of the vehicle oil tank. And acquiring the residual electric quantity of the battery and/or the residual oil quantity of the oil tank in real time.

For example, the current state of charge and/or the current state of oil quantity are obtained in real time through the sensor, and the remaining battery capacity and/or the remaining oil quantity of the oil tank are obtained.

The process of obtaining the remaining battery power may further be: and (3) calculating the battery residual capacity of the power battery pack (Battery Management System, BMS) in real time through a vehicle hybrid system controller (Vehicle Control Unit, VCU for short) to obtain the battery residual capacity.

And 102, calculating to obtain the electric endurance mileage of the vehicle in the electric-only mode according to the residual electric quantity of the battery.

In specific implementation, the pure electric mode is that the engine does not work, the electric energy of the power battery is input into the P2 motor, and the power of the P2 motor drives wheels through the speed changer, the main speed reducer and the differential mechanism. The method is mainly suitable for vehicle starting, medium-low speed urban road conditions.

The pure electric mode is to drive the vehicle to run by only using the power battery. And calculating according to the residual electric quantity of the battery, the hundred kilometers of electricity consumption and the preset reserved electric quantity to obtain the electric endurance mileage of the vehicle in the electric-only mode. The electric endurance mileage is a vehicle endurance mileage determined according to the remaining battery power in a pure electric mode.

And step 103, calculating to obtain the mileage increase Cheng Xuhang of the vehicle engine in the direct drive mode according to the residual oil quantity of the oil tank.

When the engine is in specific implementation, the engine is in a direct drive mode, namely the engine is operated, the clutch is combined, the engine power drives wheels through the speed changer, the main speed reducer and the differential mechanism, and the engine works in a high-efficiency working condition. The method is mainly suitable for high-speed running of the vehicle.

The engine direct drive mode is to drive the vehicle to run by the engine only. And calculating according to the residual oil quantity and hundred kilometers of oil consumption of the oil tank to obtain the increase Cheng Xuhang mileage of the direct drive mode of the vehicle engine. The distance increase Cheng Xuhang is a vehicle endurance distance determined according to the residual oil quantity of the oil tank in the engine direct-drive mode.

And 104, determining a vehicle endurance state according to the electric endurance mileage and the increased Cheng Xuhang mileage, and performing vehicle control according to the vehicle endurance state in the vehicle driving distance by adopting a corresponding strategy.

In specific implementation, the vehicle endurance state is determined according to the electric endurance mileage and the increase Cheng Xuhang mileage. The vehicle endurance state is the total endurance mileage, and the total endurance mileage is the sum of the electric endurance mileage of the pure electric mode and the increased Cheng Xuhang mileage of the engine direct drive mode.

During the travel of the vehicle, a total mileage of the vehicle course is obtained. For example, during a camping travel of the vehicle, a total mileage of the camping course of the vehicle is obtained. And judging whether the vehicle can normally reciprocate in the camping path or not according to the comparison of the vehicle endurance state and the total mileage of the camping path of the vehicle. And (3) vehicle control is carried out by adopting corresponding strategies according to different vehicle endurance states, for example, a driving mode is switched or energy consumption is reduced through energy recovery, a user is reminded to charge or refuel the vehicle, and the situation that the vehicle cannot complete normal round trip of a camping path due to too low residual electric quantity of a battery or residual oil quantity of an oil tank is avoided.

Step 105, determining that the vehicle arrives at the destination, starting a smart energy management mode, and calculating the safe electric quantity of the smart energy management mode.

When the vehicle arrives at the destination, the vehicle starts an intelligent energy management mode, and the safe electric quantity of the intelligent energy management mode is calculated. For example, the smart energy management mode is a camping mode when the vehicle camps. When the vehicle reaches the camping destination, the vehicle starts a camping mode and calculates a camping safety electric quantity. Camping mode is a mode that enables a user to take camping rest when the user takes rest in the vehicle after destination camping is tired. After the vehicle end receives the camping mode starting instruction, a central electronic control module (CEM) determines a parking state, judges whether an engine range extender is started or not, determines that the engine range extender is not started, and a vehicle hybrid system controller VCU calculates the camping safety electric quantity of a battery pack in real time, so that the system normally starts the camping mode.

After the camping mode is started, the whole vehicle system executes the following actions, so that the vehicle runs with the lowest energy consumption. Camping mode vehicle system performs the actions of: (1) The back of the front-row seat is folded backwards and spliced with the back-row seat, and the seat cushion is lifted up to eliminate steps; the back row seat backrest is folded backwards to the maximum extent, and the front row seat backrest and the back row seat backrest are spliced to form a large bed mode, so that the rest in the vehicle is facilitated; (2) closing the vehicle window and locking the four door locks; (3) the lamp light delay 30S of the car light is automatically turned off (can be set); (4) the multimedia screen is extinguished, and the music is closed; (5) The air conditioner operates with the lowest energy consumption, and ensures the indoor temperature of 26 ℃ (which can be adjusted between 24 ℃ and 28 ℃ according to different personal requirements).

And step 106, in response to determining that the safe electric quantity is lower than a preset first electric quantity threshold value, exiting the intelligent energy management mode.

In specific implementation, when the safe electric quantity is lower than a preset first electric quantity threshold value, in order to ensure enough electric quantity to return to the navigation, the system prompts that the safe electric quantity is insufficient and exits from the intelligent energy management mode.

In the above embodiment, the electric range of the vehicle in the electric-only mode is calculated according to the remaining battery power. And calculating according to the residual oil quantity of the oil tank to obtain the mileage increase Cheng Xuhang of the vehicle engine in the direct drive mode. And determining a vehicle endurance state according to the electric endurance mileage and the increased Cheng Xuhang mileage, and performing vehicle control according to the vehicle endurance state in the vehicle driving distance by adopting a corresponding strategy. The intelligent planning control of the vehicle electric quantity and the oil quantity can be realized, so that a user can know the vehicle residual electric quantity and the oil quantity in time. In addition, the vehicle is controlled by adopting a corresponding strategy according to the vehicle endurance state, so that the situation that the user driving experience is influenced due to excessive consumption of the vehicle electric quantity is avoided. And determining that the vehicle reaches a destination, starting an intelligent energy management mode, and calculating the safe electric quantity of the intelligent energy management mode. And in response to determining that the safe power is below a preset first power threshold, exiting the smart energy management mode. When the safe electric quantity is exhausted, the intelligent energy management mode is timely exited, and the problem of insufficient return electric quantity storage can be avoided.

In some embodiments, step 102 comprises:

in step 1021, a determination is made as to the type of the route.

In the specific implementation, the electric endurance mileage of the vehicle in the electric-only mode is calculated. Before calculating the electric endurance mileage, judging the journey type of the vehicle trip. The route type includes a normal road section and a complex road section. Hundred kilometers of electricity consumption is different for different route types. The distance of the vehicle travel can be all normal road sections, can be all complex road sections, and can be part of normal road sections and part of complex road sections. Different calculation modes are adopted for different route types.

And step 1022, in response to determining that the route type is a normal route, calculating according to the remaining battery power, the preset reserved power and the hundred kilometers of power consumption to obtain a first electric endurance mileage.

In specific implementation, when the route type is a normal road section, a first electric endurance mileage is obtained. The first electric range is an electric range of a vehicle running on a normal road section in a pure electric mode.

The calculation process of the first electric endurance mileage is as follows: first electric endurance mileage= (battery remaining amount-preset reserved amount)/(hundred km power consumption). The preset reserved electric quantity is preset electric quantity reserved for resting of the user. For example, the preset reserved power is 50% of the total power of the battery, and the first electric endurance mileage= (battery remaining power-50% x total power of the battery)/(hundred kilometers power consumption).

Step 1023, in response to determining that the route type is a complex road section, calculating according to the first electric range and a preset electricity consumption coefficient to obtain a second electric range.

In specific implementation, when the route type is a complex road section, the second electric endurance mileage is obtained. The second electric range is an electric range of the vehicle running on a complex road section in the pure electric mode. The complex road sections comprise mountain road sections, because outdoor rugged road conditions such as up-down slopes of the complex road sections are complex, the hundred kilometer electricity consumption of the complex road sections is more than that of the normal road sections, and the hundred kilometer electricity consumption of the complex road sections is calculated according to preset multiples of the hundred kilometer electricity consumption of the normal road sections, wherein the preset multiples are preset electricity consumption coefficients.

The calculation process of the second electric endurance mileage is as follows: second electric range= (battery remaining amount-preset reserved amount)/(preset electricity consumption coefficient×hundred kilometers electricity consumption) =first electric range/(preset electricity consumption coefficient). For example, if the preset power consumption coefficient is 1.5, the second electric range=the first electric range≡1.5.

In the scheme, the electric endurance mileage in the pure electric mode is calculated, so that a user can know the residual electric quantity of the battery of the vehicle and the electric endurance mileage which can be driven by the residual electric quantity of the battery in time. Since the hundred kilometers of electricity consumption of the complex road section is different from that of the normal road section. And judging the type of the journey, and calculating the electric endurance mileage by adopting different modes for different journey types, so that the calculated electric endurance mileage is more accurate and meets the actual situation.

In some embodiments, step 103 comprises:

step 1031, determining the route type.

In specific implementation, the mileage increase Cheng Xuhang of the vehicle engine direct drive mode is calculated during the engine direct drive mode. Before calculating the mileage increase Cheng Xuhang, the journey type of the vehicle trip is judged. The route type includes a normal road section and a complex road section. The hundred kilometers of different route types have different oil consumption. The distance of the vehicle travel can be all normal road sections, can be all complex road sections, and can be part of normal road sections and part of complex road sections. Different calculation modes are adopted for different route types.

And step 1032, in response to determining that the route type is a normal road section, calculating according to the residual oil quantity and hundred kilometers of oil consumption of the oil tank, and obtaining a first mileage increase Cheng Xuhang.

In specific implementation, when the route type is a normal road section, the first increase Cheng Xuhang mileage is obtained. The first mileage increase Cheng Xuhang is Cheng Xuhang mileage increase of the vehicle in a normal road section running in the engine direct drive mode.

The calculation process of the first increment Cheng Xuhang mileage is as follows: first increase Cheng Xuhang mileage = remaining fuel in tank +.hundred kilometers fuel consumption.

And step 1033, in response to determining that the route type is a complex road section, calculating according to the first increase Cheng Xuhang mileage and a preset oil consumption coefficient to obtain a second increase Cheng Xuhang mileage.

In specific implementation, when the route type is a complex road section, the second increase Cheng Xuhang mileage is obtained. The second mileage increase Cheng Xuhang is Cheng Xuhang mileage increase when the vehicle runs on a complex road section in the engine direct drive mode. The complex road sections comprise mountain road sections, because outdoor rugged road conditions such as up-down slopes of the complex road sections are complex, the hundred kilometer oil consumption of the complex road sections is more than that of the normal road sections, and the hundred kilometer oil consumption of the complex road sections is calculated according to preset multiples of the hundred kilometer oil consumption of the normal road sections, wherein the preset multiples are preset oil consumption coefficients.

The calculation process of the second increment Cheng Xuhang mileage is as follows: second increase Cheng Xuhang mileage = fuel remaining in the tank +.a (preset fuel consumption factor x hundred kilometers fuel consumption) = first increase Cheng Xuhang mileage +.a preset fuel consumption factor. For example, the preset fuel consumption coefficient is 1.5, and the second increase Cheng Xuhang mileage=the first increase Cheng Xuhang mileage ≡1.5.

In the scheme, the increase Cheng Xuhang mileage under the direct driving mode of the engine is calculated, so that a user can know the residual oil quantity of the vehicle oil tank and the increase Cheng Xuhang mileage which can be driven by the residual oil quantity of the oil tank in time. Since the hundred kilometers of the complicated road section are different from those of the normal road section. And judging the type of the journey, and calculating the mileage increase Cheng Xuhang by adopting different modes for different journey types, so that the calculated mileage increase Cheng Xuhang is more accurate and accords with the actual situation.

In some embodiments, step 104 comprises:

step 1041, in response to determining that the electric range is less than or equal to a preset electric range threshold, exiting the electric-only mode, starting the engine direct-drive mode, and controlling the engine range extender to start and perform energy recovery.

In the specific implementation, the total round trip distance of the vehicle is obtained in the running process of the vehicle. And judging whether the vehicle can complete normal round trip of the journey or not according to the comparison of the vehicle endurance state and the round trip total journey of the vehicle. And adopting corresponding strategies to control the vehicle according to different vehicle endurance states.

When the electric range is smaller than or equal to a preset electric range threshold, determining that the vehicle cannot be controlled to run in the pure electric mode, and controlling the vehicle to switch to an engine direct-drive mode. For example, when the electric endurance mileage is less than or equal to 0 km, the whole vehicle hybrid system controller VCU controls the engine range extender to start, starts the engine direct-drive mode, and exits the electric-only mode. In addition, energy recovery is turned on to charge the battery pack at maximum recovery efficiency.

Step 1042, in response to determining that the electric range is greater than a preset electric range threshold, and the vehicle range state is greater than or equal to the total round trip distance, controlling the vehicle according to the hybrid strategy.

When the electric endurance mileage is greater than a preset electric endurance mileage threshold and the vehicle endurance state is greater than or equal to the total round trip distance, determining the remaining battery capacity and the remaining oil quantity of the oil tank of the vehicle to complete the round trip distance, and controlling the vehicle to run according to the original hybrid power strategy. The vehicle endurance state is the sum of electric endurance mileage and Cheng Xuhang mileage increment. For example, when the electric range is greater than 0 km and the sum of the electric range and the increase Cheng Xuhang range is greater than or equal to the total round trip distance, the vehicle is controlled to travel according to the original hybrid strategy.

Step 1043, in response to determining that the electric range is greater than a preset electric range threshold, and the vehicle range state is less than the total round trip distance, prompting in a range of a preset distance from the gas station or the charging station.

When the electric endurance mileage is larger than a preset electric endurance mileage threshold, but the vehicle endurance state is smaller than the total round trip distance, the vehicle is determined to be capable of controlling the vehicle to run in a pure electric mode, the remaining battery capacity and the remaining oil of the oil tank cannot complete the round trip distance, and the vehicle is prompted when the vehicle runs within a preset distance range from a gas station or a charging station. The vehicle endurance state is the sum of electric endurance mileage and Cheng Xuhang mileage increment. For example, when the electric range is greater than 0 km, but the sum of the electric range and the mileage increment Cheng Xuhang is smaller than the total round trip distance, the distance between the vehicle and the gas station or the charging station is calculated, and when the vehicle travels within a preset distance range from the gas station or the charging station, a broadcasting prompt is sent to remind the user to refuel or charge.

In the scheme, the vehicle endurance state determined by the electric endurance mileage and the increase Cheng Xuhang mileage is controlled by adopting corresponding strategies according to different vehicle endurance states. The intelligent planning control of the electric quantity and the oil quantity of the vehicle can be realized, the situation that the vehicle cannot complete normal round trip of the journey due to the fact that the residual electric quantity of the battery or the residual oil quantity of the oil tank is too low is avoided, and the situation that the travel experience of a user is influenced due to the fact that the oil quantity of the electric quantity of the vehicle is excessively consumed is avoided.

In some embodiments, further comprising:

step 107, calculating the sustainable time of the intelligent energy management mode according to the safe electric quantity, and taking the sustainable time as rest time.

In specific implementation, the sustainable time of the intelligent energy management mode is calculated according to the safe electric quantity, and the sustainable time is used as the rest time. The rest time is calculated by the following steps: rest time = safe power +.smart energy management mode power consumption per minute. In addition, the user can set the rest time according to the own needs.

And step 108, performing vehicle control in the intelligent energy management mode in the rest time.

When the intelligent energy management mode is started, the whole vehicle system executes the following actions in the rest time, so that the vehicle runs with the lowest energy consumption. The actions performed by the intelligent energy management mode whole vehicle system include: (1) The back of the front-row seat is folded backwards and spliced with the back-row seat, and the seat cushion is lifted up to eliminate steps; the back row seat backrest is folded backwards to the maximum extent, and the front row seat backrest and the back row seat backrest are spliced to form a large bed mode, so that the rest in the vehicle is facilitated; (2) closing the vehicle window and locking the four door locks; (3) the lamp light delay 30S of the car light is automatically turned off (can be set); (4) the multimedia screen is extinguished, and the music is closed; (5) The air conditioner operates with the lowest energy consumption, and ensures the indoor temperature of 26 ℃ (which can be adjusted between 24 ℃ and 28 ℃ according to different personal requirements).

In response to determining that the rest time is over, the smart energy management mode is exited 109.

In particular, when the vehicle is in the intelligent energy management mode, the vehicle exits the intelligent energy management mode when the safety electric quantity is lower than a preset first electric quantity threshold value, and the vehicle also exits the intelligent energy management mode when the rest time is over.

When a user camps, the intelligent energy management mode is a camping mode, and the rest time is a camping time.

The process of exiting camping mode at the end of camping time is: and automatically exiting the camping mode when the calculated camping time or the camping time set by the user is finished. In order to ensure the experience of the user when the camping mode exits, the multimedia is internally provided with graceful music, and the user can select a music playing mode, wherein the music playing mode comprises: sequential play mode, cyclic play mode, and random play mode. And automatically exiting the camping mode after the graceful music with preset duration is played according to the music playing mode set by the user. For example, after graceful music is played at random for 1 minute, the camping mode is automatically exited.

The process of exiting the camping mode when the camping safety electric quantity is lower than the first electric quantity threshold value is as follows: when the camping safety electric quantity is lower than a preset first electric quantity threshold value, in order to ensure enough electric quantity to return to the voyage, the system prompts that the safety electric quantity is insufficient by voice, and the camping mode is exited. For example, the preset first power threshold is 0, and when the camping safety power is lower than 0, the camping mode is exited.

In the above scheme, the intelligent energy management mode can be exited under the condition that the rest time is over or the safe electric quantity is lower than the preset first electric quantity threshold value. The intelligent energy management time is set according to the self requirement, and meanwhile, enough electric quantity can be guaranteed to return to the voyage.

In some embodiments, step 105 comprises:

step 105A, a first distance between the vehicle and the charging station is obtained.

And 105B, calculating according to the residual capacity of the battery, the first distance and hundred kilometers of electricity consumption to obtain the safe electric quantity.

In specific implementation, before the safe electric quantity is calculated, the increase Cheng Xuhang mileage and the trip return mileage are judged. When the distance Cheng Xuhang is greater than the return distance, the vehicle can complete the return distance through the engine direct drive mode, and the calculation of the safe electric quantity can be performed without the first distance between the vehicle and the charging station.

In order to ensure that the vehicle has enough battery remaining capacity to reach the nearest charging station for charging in the way of returning, the safe electric quantity of the vehicle is calculated. The calculation process of the safe electric quantity is as follows: safe charge = battery remaining charge-first distance x hundred kilometers power consumption.

Step 105a, the total battery power is obtained.

And 105b, calculating according to the total electric quantity of the battery and a preset safety coefficient to obtain the safety electric quantity.

When the vehicle can complete the return journey through the engine direct drive mode, the safety electric quantity of the vehicle is calculated in order to ensure the normal use of the vehicle battery pack. The calculation process of the safe electric quantity is as follows: safe charge = total battery charge x preset safety factor. For example, when the preset safety coefficient is 10%, that is, when the remaining battery power is not less than 10% of the total battery power, the normal use of the battery pack can be ensured, and the service life loss of the battery pack is avoided. At this time, the safe charge=the total charge of the battery×10%.

In the above scheme, the safe electric quantity is calculated according to a first distance between the vehicle and the charging station or a preset safety coefficient. Under the condition that the user is guaranteed to have enough electric quantity to go to the charging station for charging, the experience of the intelligent energy management mode of the user is improved.

In some embodiments, after step 101, further comprising:

step 101A, in response to determining that the remaining battery power is less than or equal to a preset second power threshold, controlling the vehicle to start a power saving mode.

In specific implementation, after the vehicle runs on electricity, the vehicle hybrid system controller VCU calculates the battery residual capacity of the power battery pack in real time, and when the battery residual capacity is smaller than or equal to a preset second electric capacity threshold value, the vehicle is controlled to start a power saving mode. For example, the preset second power threshold is 50% of the total power of the battery pack, and when the remaining power of the battery is less than or equal to 50% of the total power of the battery pack, the vehicle is controlled to start the power saving mode.

The actions executed by the whole vehicle system in the power saving mode comprise: (1) The multimedia music and video functions in the vehicle cabin are closed, and the vehicle-mounted screen is adjusted according to the power saving mode except for the navigation requirement; (2) The air conditioner is selectively turned on or off according to the indoor temperature, when the indoor temperature is between 23 ℃ and 28 ℃, the air conditioner is maintained to operate with the lowest energy consumption, the air conditioner is switched to an automatic mode (namely an AUTO mode), and the air quantity, the temperature and the mode all operate with the lowest energy consumption; the indoor temperature is not between 23 ℃ and 28 ℃, and the existing opening state of the air conditioner is kept; (3) In-vehicle lights (e.g., reading lights, wall lights, and atmosphere lights) are off; (4) The comfort functions of the individual seats in the cabin are closed, such as the seat heating, massaging and ventilation functions.

In the above scheme, when the remaining battery power calculated by the vehicle hybrid system controller VCU is less than or equal to a preset second power threshold, the vehicle is controlled to start the power saving mode. The power consumption is reduced, and the vehicle is ensured to have enough power to support the round trip distance, and the intelligent energy management mode is started to rest after the vehicle reaches the destination.

It should be noted that the embodiments of the present disclosure may be further described in the following manner:

The system acquires user camping demand information through navigation destination information, and the multimedia system is used for prompting whether to start or not in a voice mode, and can also be used for actively requesting to start a camping mode by a driver, after the driver confirms, the function is started, and the following strategies are mainly executed:

case one: after the vehicle is electrified and runs, the whole hybrid system controller VCU starts to calculate the electric quantity of a power battery pack (BMS).

a. camping safe charge = battery remaining charge-first distance between vehicle and charging station x hundred kilometers of electricity consumption (increase Cheng Xuhang mileage may not be considered when meeting demand);

b. camping safety charge = battery total charge x 10%;

c. camping safe charge/air conditioning energy saving mode power = camping mode longest sustainable time (i.e., camping time).

(2) After the camping resting mode is started, the whole vehicle system executes the following actions, so that the vehicle runs with the lowest energy consumption.

a. The back of the front-row seat is folded backwards and spliced with the back-row seat, and the seat cushion is lifted up to eliminate steps; the back row seat backrest is folded backwards to the maximum extent, and the front row seat backrest and the back row seat backrest are spliced to form a large bed mode, so that the rest in the vehicle is facilitated;
