Particularly, under the condition of insufficient battery power, if the vehicle encounters a traffic jam road section, the vehicle needs to be frequently started, accelerated and braked, and meanwhile, the engine is in an inefficient working state, so that energy consumption is increased. Therefore, a method is needed to solve the problem of higher energy consumption when the vehicle encounters a traffic jam condition under the condition of insufficient battery power of the vehicle.
The embodiment discloses an energy-saving driving method of a hybrid electric vehicle type, referring to fig. 1, comprising the following steps:
s110, a first road section through which a preset vehicle needs to pass is obtained.
The energy-saving driving method of the oil-electricity hybrid electric vehicle type is applied to a control system of a preset vehicle, and the control system at least comprises a vehicle power assembly control system, an energy management control system, a kinetic energy recovery system, a battery management system and a vehicle machine control system. Wherein, the vehicle powertrain control system is responsible for managing the power source, distribution and conversion of the vehicle to optimize drivability, fuel efficiency and energy utilization. In a hybrid vehicle model, this control system will coordinate the co-operation between the internal combustion engine and the electric motor, selecting the appropriate drive mode and energy distribution strategy depending on the driving conditions and driver demand. The energy management control system is used to monitor the energy flow of the vehicle, including the use of electrical energy and fuel. It decides when to use the electric mode, when to start the internal combustion engine, when to perform energy recovery, etc., based on the prediction model, driving behavior, and road condition information, to achieve the optimal energy utilization efficiency. The kinetic energy recovery system is capable of utilizing kinetic energy generated during braking to convert it into electrical energy and store it in a battery. It can recover energy during deceleration and braking, and reduce energy consumption. The battery management system is used to monitor the state, temperature and charge of the battery to ensure safe operation and optimal performance of the battery. The vehicle control system is an intelligent control system integrated in the automobile and is used for managing functions of entertainment, navigation, communication and the like of the vehicle. The vehicle control system can be connected with the Internet through a mobile cellular network and provides a positioning navigation function for the vehicle by combining with a GPS positioning navigation system.
The vehicle-machine control system of the preset vehicle provides an intuitive human-machine interaction interface, so that a user can interact with the control system through a touch display screen, voice input or physical button operation. When a user needs to drive a preset vehicle to run to a certain place, the terminal point can be input through the vehicle-to-machine control system, and then the control system obtains the terminal point input by the user. Meanwhile, the vehicle-mounted control system acquires the current position of the preset vehicle through the GPS positioning navigation system, and performs path planning by combining electronic map data and traffic information based on the current position and the terminal point input by a user to obtain a plurality of preset routes. Meanwhile, the vehicle control system can acquire traffic data including traffic jam information by adopting the map data and an API interface of the traffic information provider, so as to determine the road section length of the traffic jam road section in each preset route. For example, if there are three traffic segments in total in a certain preset route, the lengths are 1 km, 1.2 km and 2.3 km respectively, the segment length of the traffic segment is the sum of the three lengths of 4.5 km.
Further, the plurality of traffic jam road sections are ordered according to the road section length, the traffic jam road section with the shortest road section is determined according to the ordering result, the preset route corresponding to the traffic jam road section is sent to a vehicle screen, and navigation is provided on the vehicle screen. If the length of the shortest traffic jam section is zero, the following energy planning is not performed. If the length of the shortest traffic jam section is greater than zero, the traffic jam section is set as the first section. The method comprises the steps of obtaining a terminal point input by a user, presetting the current position of a vehicle, planning a path to obtain a plurality of preset routes, determining the road section length of a traffic jam road section in each preset route, and sequencing the plurality of road section lengths, so that the traffic jam road section with the shortest road section, namely the first road section, is determined. The lengths of the road sections are sequenced, so that the traffic jam road section with the shortest road section, namely the first road section, can be determined, and the energy consumption caused by traffic jam can be reduced.
S120, determining a first mileage of the first road section and presetting a first duration for the vehicle to spend passing through the first road section.
At present, an electronic map acquires real-time traffic data, including data of road traffic flow, speed, traffic incidents and the like through cooperation with a traffic department. The data can help the electronic map to judge the congestion degree of the road and calculate the length of the road section of the traffic jam. The electronic map also analyzes the congestion condition of the road by collecting travel data of the user, including travel track, travel speed, travel time and the like. By analyzing a large amount of user data, the congestion degree of the road in different time periods and the time required for passing through the traffic jam road section can be obtained. The map data of the electronic map contains information of roads, including shapes, intersections, traffic lights, and the like of the roads. By analysing the map data, the length of the road segments, and possibly the speed of travel, can be calculated, so that the time required to pass the road segments can be predicted. The control system can acquire the length of the first road section, namely the first mileage, and acquire the duration required by the preset vehicle to pass through the first road section, namely the first duration through the data provided by the electronic map.
S130, determining a first electric quantity required to be consumed by a preset vehicle passing through a first road segment based on the first mileage and the first time length.
After the control system obtains the first mileage of the first road section and the first time length required by the preset vehicle to pass through the first road section, the average speed of the preset vehicle passing through the first road section can be calculated by dividing the first mileage by the first time length. In a stationary state of a preset vehicle, electronic equipment such as an air conditioner, a vehicle screen and a vehicle-mounted sound device of the vehicle can consume energy, and for a hybrid vehicle type, the energy is provided by a vehicle battery. The energy consumption of the vehicle in a stationary state can thus be calculated by means of the charge data and the voltage data of the battery monitored by the battery management system. Similarly, according to the battery historical electric quantity data and the voltage data stored by the battery management system, the energy consumption of the preset vehicle in the running state of different speeds is calculated.
According to the data, calculating the total energy consumption required to be consumed by the preset vehicle through the first road segment by a preset formula, wherein the preset formula is as follows:
;
wherein E is 1 L is the first mileage, v 1 For presetting the average speed of the vehicle passing through the first road section, a is the energy consumption of the preset vehicle in a static state, and b is the energy consumption increment of the preset vehicle in a driving state.
To better understand this formula, a specific example is given. Assuming that the energy consumption of the vehicle in a stationary state is 10 joules/second, the energy consumption increment in a driving state is 0.5 joules/second 2, the length of the first road section is 1000 meters, and the average speed of the preset vehicle passing through the first road section is 10 meters/second, the energy consumption of the preset vehicle calculated according to the preset formula and passing through the traffic jam road section is 1100 joules. And finally, converting the total energy consumption into first electric quantity according to the conversion ratio between joules and kilowatt-hours to obtain the electric quantity required to be consumed by the preset vehicle through the first road segment.
When the total energy consumption required to be consumed by the preset vehicle passing through the first road section is calculated, the running distance, the average speed and the energy consumption condition of the vehicle in the static and running states are comprehensively considered, so that the energy consumption requirement of the vehicle on the traffic jam road section can be accurately predicted, and more accurate data support can be provided for subsequent electric quantity management.
S140, determining the residual quantity of the preset vehicle.
And S150, judging whether the residual electric quantity is smaller than the first electric quantity, and if the residual electric quantity is smaller than the first electric quantity, determining the second mileage.
When the preset vehicle is started, the battery management system is used as a control system of the battery pack and is responsible for monitoring parameters such as voltage, electric quantity and temperature of the battery and controlling the charging and discharging processes of the battery. And the battery management system monitors the battery power data so as to obtain the residual power of the preset vehicle. And judging whether the residual electric quantity is smaller than the first electric quantity or not, namely judging whether the residual electric quantity of the preset vehicle is enough to enable the preset vehicle to pass through the first road segment or not. If the residual electric quantity is larger than the first electric quantity, namely the residual electric quantity of the preset vehicle is enough to enable the preset vehicle to pass through the first road segment, the control system judges whether the residual electric quantity is smaller than the first electric quantity in real time before the preset vehicle runs to the starting point of the first road segment. Before the preset vehicle runs to the starting point of the first road segment, if the residual electric quantity is smaller than the first electric quantity, a starting instruction is sent to the vehicle power assembly control system, so that the vehicle power assembly control system controls the engine of the preset vehicle to start, and the generator of the preset vehicle is driven to supply power.
Under the condition that the residual electric quantity is larger than the first electric quantity, whether the residual electric quantity is smaller than the first electric quantity or not is judged in real time, the condition of insufficient electric quantity can be found in time, and the condition of electric quantity exhaustion before the vehicle reaches the starting point of the first road segment is avoided. When the residual electric quantity is smaller than the first electric quantity, the engine is started and the generator is driven to supply power, so that the vehicle can be ensured to have enough electric quantity when reaching the starting point of the first road segment, and the following energy requirement can be met.
If the residual electric quantity is smaller than the first electric quantity, namely the residual electric quantity of the preset vehicle is not enough to enable the preset vehicle to pass through the first road section, the control system calculates the mileage between the preset vehicle and the starting point of the first road section from the current position according to the navigation data, and the second mileage is obtained.
The control system predicts the time required by the preset vehicle to run out of the second mileage according to the navigation data, thereby obtaining the average speed of the preset vehicle to run out of the second mileage. Based on the data, the control system predicts the total recovery amount of kinetic energy before the preset vehicle runs to the starting point of the first road segment, and specifically calculates the total recovery amount of kinetic energy through the following formula:
;
wherein E is 2 For the total amount of the kinetic energy recovery, k 1 For the efficiency of the preset vehicle kinetic energy recovery system, v 2 An average speed of the second mileage after the preset vehicle is driven, d is the second mileage, k 2 And driving the second mileage for the preset vehicle.
The preset efficiency of the kinetic energy recovery system of the vehicle refers to the ability to convert kinetic energy of the vehicle traveling into electric energy and store the electric energy in an energy storage system such as a battery. This efficiency is affected by a number of factors, including the performance of the motor, battery, controller, etc., components, the running state of the vehicle, etc. It is necessary to acquire the efficiency of the vehicle kinetic energy recovery system through real vehicle testing or referring to data of similar vehicle models. In the test, the efficiency of the system can be calculated by comparing the energy consumption of the vehicle in the working state and the normal running state of the kinetic energy recovery system. The efficiency of the vehicle kinetic energy recovery system is such that it directly affects the total energy that can be recovered during the travel of the vehicle.
The speed change coefficient is to consider the influence of the change in speed of the vehicle during running on the recovery of kinetic energy. Because the vehicle may experience different conditions of acceleration, deceleration, and constant velocity during travel, the energy recovery in these conditions may also vary. The values may be obtained by real vehicle testing or referencing data of similar vehicle models. By testing the energy recovery data under multiple sets of different speed changes, a coefficient reflecting the influence of the speed changes on the energy recovery can be fitted. The speed change coefficient is introduced to more accurately predict the total energy that can be recovered by kinetic energy for a certain distance traveled by the vehicle. Since during actual driving a change in speed is unavoidable and this coefficient may reflect the influence of the change in speed on the energy recovery. By considering the factor, the total energy of the kinetic energy recovery can be predicted more accurately, and a more targeted optimization suggestion is provided for energy conservation and emission reduction of the vehicle.
By taking into account factors such as the average speed and the speed variation of the preset vehicle running, the total amount of kinetic energy recovery can be calculated more accurately. Specifically, the first term (k 1 ×v 2 X d) is a kinetic energy recovery amount based on a preset vehicle travel distance and average speed, and the second term (k 2 ×v 2 2 X d) is the amount of recovery of kinetic energy based on the preset vehicle travel distance and speed variation. By passing throughThe total amount of kinetic energy which can be recovered in the running process of the preset vehicle can be more comprehensively estimated by comprehensively considering the two items.
S160, outputting an energy storage instruction to an energy management control system of the preset vehicle so as to enable the preset vehicle to store second electric quantity in the process of driving the second mileage.
According to the second electric quantity required to be used by the preset vehicle through the first road segment and the current residual electric quantity of the preset vehicle, a difference value is obtained, and the second electric quantity required to be stored by the preset vehicle is larger than or equal to the difference value, so that the preset vehicle enables the vehicle to pass through the first road segment through electric energy supply without an engine to work.
And judging whether the total recovery amount of the kinetic energy is smaller than the second electric quantity, if the total recovery amount of the kinetic energy is larger than or equal to the second electric quantity, starting a vehicle power assembly control system is not needed, and the total recovery amount of the kinetic energy is enough to preset the vehicle to enable the vehicle to pass through the first road section through electric energy supply. If the total recovered kinetic energy is smaller than the second electric quantity, determining an energy difference value according to the total recovered kinetic energy and the second electric quantity, wherein the energy difference value is the electric quantity which is required to be provided by the vehicle power assembly control system.
And then in the running process of the preset vehicle, the control system acquires the real-time speed of the preset vehicle and judges whether the real-time speed is larger than a preset threshold value, wherein the preset threshold value is required to be set according to the engine efficiency of the preset vehicle, so that when the motor refers to the preset threshold value from the speed per hour of the preset vehicle, the engine is started to work, and the lower efficiency caused by the low-speed work of the engine is prevented. And when the real-time speed is greater than the preset threshold value, sending a starting instruction to the vehicle power assembly control system so that the vehicle power assembly control system controls the engine of the preset vehicle to start and drives the generator of the preset vehicle to supply power to the battery pack. In the power supply process, the generated energy provided by the generator is obtained in real time, whether the generated energy is larger than or equal to the third electric quantity or not is judged, and if the generated energy is larger than or equal to the third electric quantity, a stop instruction is sent to the vehicle power assembly control system, so that the vehicle power assembly control system controls the engine of the preset vehicle to stop working. Judging whether the real-time speed of the preset vehicle is greater than a preset threshold value, and starting the engine to work when the speed is greater than the preset threshold value. The preset threshold value can be set according to the conditions of different vehicles, so that the engine is started when the speed of the preset vehicle is high, and the high energy consumption caused by the low-speed operation of the engine is prevented. By capturing the amount of power generated by the generator, it can be determined whether the engine is providing sufficient power to meet the needs of the vehicle. When the amount of power generation is greater than or equal to the third amount of power, it is indicated that the engine has provided sufficient power, and a stop command is sent to control the engine to stop operating, so as to avoid unnecessary power consumption and emission.
And under the condition that the total quantity of recovered kinetic energy is smaller than the second electric quantity, determining an energy difference value according to the total quantity of recovered kinetic energy and the second electric quantity, and then sending an energy supply instruction to a vehicle power assembly control system so as to supply enough electric quantity (third electric quantity) to ensure that the energy required by the preset vehicle in the second mileage is met. Meanwhile, through cooperative work with the energy management control system and the vehicle power assembly control system, more accurate energy management and energy supply control can be realized, and the energy utilization efficiency of the vehicle is improved.
By adopting the technical scheme, the energy consumption of the vehicle on the traffic jam road section is predicted, whether the residual electric quantity of the vehicle passes through the traffic jam road section is judged, and the required electric quantity is stored on the non-traffic jam road section by controlling the vehicle through the energy storage instruction when the residual electric quantity of the vehicle is insufficient, so that the problem that the energy consumption is high due to the fact that the engine is used for driving when the vehicle encounters traffic jam under the condition that the electric quantity of a battery of the vehicle is insufficient is solved. Specifically, the technical scheme includes that a first road section required to be passed through by a preset vehicle is firstly obtained, the first road section is a traffic jam road section, then time required to be spent by the preset vehicle to pass through the traffic jam road section is determined, and first electric quantity required to be consumed by the vehicle to pass through the road section is calculated based on mileage and time. Then, determining the residual electric quantity of the preset vehicle, if the residual electric quantity is smaller than the required electric quantity, indicating that the preset vehicle cannot pass through the traffic jam road section through the electric energy supply of the vehicle, and determining the mileage between the current position of the vehicle and the starting point of the first road section, namely, the second mileage. And finally, outputting an energy storage instruction to an energy management control system of the vehicle so as to enable the vehicle to store the required electric quantity in the process of driving the second mileage. After the preset vehicle reaches the traffic jam section and stores enough electric quantity, the preset vehicle can be driven by the electric motor through electric energy in the traffic jam section, and the electric motor has lower energy consumption in a low-speed driving state compared with an engine, so that the problem that the energy consumption is higher when the vehicle encounters traffic jam under the condition of insufficient electric quantity of a vehicle battery can be solved.
