Detailed Description
In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The intelligent internet vehicle cruise is characterized in that driving state information of a front vehicle is transmitted to the vehicle by using V2X and signal lamp phase information under the internet environment and displayed on an HMI interface, and a driver can visually see external environment information under the internet environment.
When the vehicle is manually driven and a vehicle in front of the vehicle can cruise in an internet environment, the optimal fuel consumption and SOC state exist during cruising of the vehicle in consideration of the economic requirement, and the vehicle is displayed on an HMI interface, so that a driver can visually see the energy consumption information of the vehicle.
As shown in fig. 1, the structural block diagram of an HMI system applied to intelligent networked automobile cruise control in an embodiment of the invention is shown, the HMI system is applied to an intelligent networked hybrid electric automobile, can realize human-computer interaction in a networked environment, and external environment information is communicated with the automobile through V2X, and includes an information display module, a human-computer interaction module and an operation suggestion module. Wherein:
the information display module receives signal lamp signals, front vehicle motion state information and oil consumption during manual driving through V2X, and the oil consumption during manual driving and the battery charge state consumption value are calculated through the following formulas:
in the formula (I), the compound is shown in the specification,
indicating fuel consumption rate, SOC 0 Indicates an initial value of battery state of charge>
Represents t f Battery state of charge value at time, t f Represents the time at which the journey ended, λ represents the weight;
and acquiring the difference between the oil consumption and the battery state-of-charge consumption value during manual driving and the oil consumption and the battery state-of-charge consumption value during cruising under the same working condition calculated by the vehicle control unit, and displaying signal lamp phase information, front vehicle motion state information, the oil consumption during manual driving and the battery state-of-charge consumption value information to a driver through CAN (controller area network) transmission. The vehicle networking establishes a new automobile technology development direction by integrating a Global Positioning System (GPS) navigation technology, a vehicle-to-vehicle communication technology, a wireless communication technology and a remote sensing technology, and realizes the compatibility of manual driving and automatic driving. In brief, the vehicle model matched with the system can automatically select the driving route with the best road condition through analyzing the real-time traffic information in an automatic driving mode, thereby greatly relieving traffic jam. In addition, by using the vehicle-mounted sensor and the camera system, the surrounding environment can be sensed and quickly adjusted, so that zero traffic accidents are realized. For example, if a pedestrian suddenly appears, it may be automatically decelerated to a safe speed or stopped.
The operation suggestion module is used for outputting a driving suggestion for entering a cruising mode to a driver when the difference between the oil consumption and the battery charge state consumption value of the intelligent internet hybrid electric vehicle during manual driving and the oil consumption and the battery charge state consumption value during cruising under the same working condition exceeds a preset threshold value.
The man-machine interaction module plays a role in sending a specific control instruction to the vehicle when the driver patrols the intelligent internet vehicle.
The driver can determine whether to pass the signal lamp and whether to enter the cruise mode according to the signal lamp phase information and the driving state information of the front vehicle displayed by the information display module, can also determine whether to enter the cruise mode according to the driving suggestion given by the operation suggestion module, and can switch from the manual driving mode to the cruise mode through the man-machine interaction module if the driver determines to enter the cruise mode.
The specific working process is as follows:
in the manual driving mode, when the vehicle enters the internet connection environment, the message display module of the HMI is activated and displays information of the external surrounding environment of the vehicle, the oil consumption of the vehicle and the SOC consumption value of the battery. When a vehicle is traveling ahead of the vehicle, the message module of the HMI displays fuel consumption in cruise mode and a battery SOC consumption value. When the difference between the fuel consumption and the SOC consumption value of the battery during manual driving and the fuel consumption and the SOC consumption value of the battery during cruising under the same working condition exceeds a set threshold value, the operation suggestion module of the vehicle is activated. When the driver accepts the suggestion and needs to enter the cruise mode, the operation is switched to the cruise mode through the man-machine interaction module. When the vehicle is in a cruising mode and the vehicle is about to pass through a signal lamp, the driving state information of the vehicle in front and the phase information of the signal lamp are displayed on the message display module, and a driver can judge whether to continue cruising or whether to pass through a traffic light through the information, select the information through the man-machine interaction module, give an instruction to the vehicle and wait for the vehicle to execute.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
