In order to better understand the technical solution and the technical effect of the present invention, the following detailed description of specific embodiments will be made with reference to fig. 1 to 2.
The following describes the vehicle control unit of the electric vehicle in further detail with reference to the accompanying drawings.
As shown in fig. 1, the present embodiment provides a vehicle control unit of an electric vehicle, which is used for intelligent control of air conditioning and power. The electric automobile in the embodiment includes air conditioner, battery module and transmission system, and this vehicle control unit includes: the road condition obtaining module 200 is configured to obtain current driving road condition information of the electric vehicle; the air conditioner state acquisition module 300 is used for acquiring air conditioner state information of the electric automobile; the vehicle speed information acquiring module 400 is used for acquiring the current vehicle speed information of the electric vehicle; the control module 100 is configured to control the transmission system according to the current driving road condition information obtained by the road condition obtaining module 200, the air conditioner state information obtained by the air conditioner state obtaining module 300, and the current vehicle speed information obtained by the vehicle speed information obtaining module 400. In the embodiment, the intelligent control of the air conditioner and the power is to evaluate the user requirements and the vehicle running conditions through the acquired various information, so that the most appropriate control strategy is adopted, the requirements of the user are met to the maximum extent, and the user experience is improved. The information includes driving road condition information, air conditioner running state, vehicle running speed and the like, and the information is acquired by the corresponding information acquisition module.
Specifically, the road condition obtaining module 200 may obtain the driving road condition information of the electric vehicle through multiple ways, for example, the number of vehicles around the vehicle is monitored through a radar to determine the congestion degree, whether the vehicle is in the congestion state is determined by monitoring the number of times of starting and stopping the vehicle, what kind of road surface the vehicle is on is determined by monitoring the posture of the vehicle body, and the like.
The air conditioner state information acquired by the air conditioner state acquiring module 300 includes not only the preset temperature and the operating temperature of the air conditioner, but also the operating state of the air conditioner compressor, such as the operating power of the compressor.
The vehicle speed information acquired by the vehicle speed information acquisition module 400 is used for judging whether the vehicle running state belongs to a low speed, a medium speed or a high speed, and the corresponding control strategies in different running states are different.
The control module 100 comprehensively analyzes the acquired information, selects the most reasonable control strategy, and controls the transmission system, so that the reasonable distribution of the power of the electric automobile and the operating power of the air conditioner is realized, the requirements of users are met to the maximum extent, and energy is saved. Specifically, when the demand of the user for power is large, such as a congested road section of an automobile, and the user needs a large starting acceleration, the control module 100 controls the transmission system to meet the power demand to the maximum extent by controlling the gearbox, and appropriately limits the operating power of the air conditioner if necessary; when the power demand of the user is small, the control module 100 can appropriately improve the operating power of the air conditioner while ensuring the notification of the power demand, and different control strategies can be adopted for different road conditions and different user demands without manually selecting a driving mode by the user, thereby being beneficial to improving the use experience of the user.
Further, as shown in fig. 2, the control module 100 includes: a traffic pattern analysis unit 101, configured to obtain a current traffic pattern according to the driving traffic information, where the traffic pattern includes a power priority pattern and a conventional high-speed pattern; and the control unit 102 is configured to control the transmission system according to the road condition mode when the electric vehicle is in an acceleration state and the air conditioner is in an on state. The control module 100 needs to perform comprehensive analysis on the information acquired by the plurality of information acquisition modules, the function of the part is completed by the road condition mode analysis unit 101, and the current vehicle is judged to be in the power priority mode or the conventional high-speed mode through analysis, the two modes correspond to different user requirements, and the corresponding control strategy emphasis points are also different. The control module 100 ultimately effects an intelligent distribution of power through control of the transmission, such as by varying the torque of the vehicle through control of the transmission gear, to achieve a desired acceleration effect.
Further, controlling the transmission system according to the road condition mode comprises: in the power priority mode, the transmission system is controlled to shift down or delay the shift up of the electric vehicle. In this mode, the user needs a better acceleration effect, and the downshift or the delay upshift can obtain a larger torque to meet the requirements of the user. Common electric automobile probably has corresponding driving mode, but needs user's oneself to select according to the demand is manual, and operation experience is not good and have certain potential safety hazard, and this part function of electric automobile in this embodiment can be realized by control module direct action on transmission system, and is more intelligent, also safer.
Further, the electric vehicle includes an accelerator pedal; the vehicle controller further comprises an accelerator pedal state acquisition module 500, configured to acquire an action amplitude of the accelerator pedal; in the power priority mode, the control unit 102 controls the transmission system according to the operation width of the accelerator pedal. The urgency degree of the power demand of the user can be most intuitively reflected to the accelerator pedal, and the demand information of the user can be more accurately acquired by monitoring the action amplitude of the accelerator pedal, so that the control strategy adopted by the control module 100 can be ensured to be most in line with the demand of the user.
Further, in the power priority mode, when the action amplitude of the accelerator pedal is lower than a preset amplitude, the transmission system is controlled to enable the electric automobile to delay the upshift, and when the action amplitude of the accelerator pedal is equal to or higher than the preset amplitude, the transmission system is controlled to enable the electric automobile to downshift. The preset amplitude is a set threshold value in a control program, so that the urgency degree of the user on the power demand is judged, and corresponding control strategies are adopted in sequence. Specifically, when the action amplitude of the accelerator pedal is lower than the preset amplitude, the requirement degree of the user for the power does not reach the highest level, and therefore only the gearbox needs to be controlled to delay the upshift; when the action amplitude of the accelerator pedal is equal to or higher than the preset amplitude, the requirement of the user on power is very urgent, and the requirement of the user can not be met only by delaying the upshift, so that the downshift with better acceleration effect is adopted at the time. Preferably, the delay time length of the electric vehicle for delaying the upshift is obtained according to the position of the whole motion amplitude of the accelerator pedal where the action amplitude of the accelerator pedal is located, for example, the whole motion amplitude of the accelerator pedal is defined as a, the amplitude a is divided into N segments, and the 1 segment and the 2 segment are sequentially arranged from the accelerator to the accelerator. . . And N, wherein N is an even number greater than or equal to 4, when the action amplitude is from 1 to N/2 and the action amplitude of the accelerator pedal is lower than a preset amplitude, the transmission system is controlled so that the electric automobile delays the upshift by a delay time t1, and when the action amplitude is from N/2 to N and the action amplitude of the accelerator pedal is lower than the preset amplitude, the transmission system is controlled so that the electric automobile delays the upshift by a delay time t2, wherein t1 is k t2, and k is 1/N.
Further, the vehicle control unit further includes an ambient temperature obtaining module 600, configured to obtain ambient temperature information; controlling the transmission system according to the road condition mode comprises: in the normal high-speed mode, the power distribution of the battery module and the output power of the compressor of the air conditioner are controlled according to the ambient temperature information acquired by the ambient temperature acquisition module 600. The conventional high-speed mode means that the electric automobile is in a running state with high speed and small fluctuation, the demand of a user on power in the running state is not urgent under a power priority mode, the user experience at the moment can be inferred through monitoring the ambient temperature, and on the basis of the inference, the control module can control the power distribution of the battery module and the output power of the compressor, and the most reasonable and energy-saving control strategy is adopted on the premise of ensuring the user experience.
Further, the control of the output power distribution of the battery module and the output power of the compressor of the air conditioner by the ambient temperature information acquired by the ambient temperature acquisition module 600 includes: when the ambient temperature is higher than the first preset temperature or is lower than the second preset temperature, the output power distribution of the battery module is preferential to the air conditioner, the conventional operation of a compressor of the air conditioner is controlled, the ambient temperature information obtained can be deduced, the user is in an environment with overhigh temperature or overlow temperature at the moment, the smooth operation of the air conditioner is guaranteed for guaranteeing the driving experience of the user, therefore, the air conditioner is selected to be preferential according to the power distribution principle of the battery module, and the smooth operation of the air conditioner compressor is guaranteed.
When the ambient temperature is lower than or equal to the first preset temperature and higher than or equal to the second preset temperature, the output power distribution of the battery module is power-priority, the output power of the compressor is controlled to be reduced, it can be estimated through the acquired ambient temperature information, the user is in an environment with a proper temperature at the moment, the influence of the air conditioner on the experience of the user is small, therefore, the output power distribution principle of the battery module can select power-priority, the output power of the compressor is reduced properly, and the most energy-saving operation mode is adopted while the user experience is not influenced.
The first preset temperature is higher than the second preset temperature, and the temperature interval between the first preset temperature and the second preset temperature is a proper temperature, so that the user experience is best in the state; a high temperature above a first predetermined temperature may be inferred as a high temperature state and a low temperature below a second predetermined temperature may be inferred as a low temperature state, both of which may be poor user experience and may avoid or adjust the temperature in time.
Further, the method for obtaining the current road condition mode from the driving road condition information comprises the following steps: when the electric automobile runs on a non-highway section or an uphill section, judging that the current road condition mode is a power priority mode; when the electric automobile runs on a highway section and is on a non-uphill section, the current road condition mode is judged to be the conventional high-speed mode. The vehicle speed information acquisition module 400 can accurately acquire the running speed of the vehicle so as to judge whether the running road section of the vehicle is in a high-speed road section or a non-high-speed road section, the posture change information of the vehicle body can be acquired through the vehicle posture sensor so as to judge whether the vehicle is in an uphill road section, the road condition analysis unit comprehensively analyzes the two kinds of information so as to judge whether the road condition mode is a power priority mode or a conventional high-speed mode, and the control unit adopts a corresponding control strategy.
Further, the vehicle control unit further includes a communication module 700, the communication module 700 is in communication connection with the server, and the road condition obtaining module 200 obtains the driving road condition information from the server through the communication module 700. In order to ensure that more comprehensive and more accurate road condition information is obtained, except for various information obtaining modules carried by the vehicle, the vehicle control unit of the electric vehicle in the embodiment further comprises a communication module 700, such as electronic navigation software and the like, which can timely obtain real-time road condition information, so that the control module 100 can be ensured to be more timely, more accurate and more intelligent, and the scientific and technological sense and the user experience of the vehicle can be promoted.
Specifically, when the vehicle runs on a congested road section in a city area, the road condition information acquisition path may be to monitor surrounding vehicles through a vehicle body radar, and if the number of surrounding vehicles is large and the distance is short, it indicates that the road condition is congested; or the conclusion can be obtained by monitoring the vehicle speed, if the running speed of the vehicle is low and the vehicle is frequently braked, the road condition is congested; the information of the traffic jam can also be directly obtained through the communication module 700, such as electronic navigation. In this state, the acceleration demand of the vehicle by the user is relatively large, so the control module 100 selects the control strategy in the power priority mode, and obtains a larger torque by controlling the gearbox to delay the upshift or the downshift, so as to provide a required larger acceleration for the user.
In addition, the vehicle has a relatively large demand for power when climbing a slope, and the road condition information can be obtained by a vehicle body posture sensor of the vehicle, and after receiving the corresponding vehicle body posture information, the road condition analysis unit 101 of the control module 100 selects the control strategy in the corresponding power priority mode.
The control module 100 controls the transmission system by considering the implementation requirements of the user, the requirements are inferred by detecting the action amplitude of the accelerator pedal, when the action amplitude of the accelerator pedal is larger, the requirement of the user on power is more urgent, and the downshift operation with better torque increasing effect can be adopted; when the action amplitude of the accelerator pedal is smaller, the requirement of a user on power is not urgent, so that the delayed upshift operation with relatively poor torque increasing effect can be adopted, and the running of the vehicle is correspondingly smoother.
When the vehicle is in a good road condition of a running state, the running speed of the vehicle is high and stable, large fluctuation cannot occur, the user does not have extra demand for the power of the vehicle in the state, the control module 100 can select a conventional high-speed mode at the moment, and in the mode, the main function of the control module 100 is to perform coordination control on the running state of the air conditioner and the power distribution of the battery module to ensure the experience of the user. When the ambient temperature monitored by the ambient temperature detection module 600 is in a high-temperature or low-temperature state, the control module 100 can preferentially ensure the operation of the air conditioner, the output power of the battery module correspondingly inclines to the air conditioner, and the stable operation of the compressor is ensured, so that the temperature is controlled to a comfortable interval as soon as possible.
When the temperature is in the comfortable interval, the demand on the air conditioner is not so urgent, and at the moment, the control module 100 can control the output power of the battery module to incline towards the power, so that the output power of the compressor is properly reduced, and sufficient power reserve is ensured, thereby saving energy and improving endurance.
