Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
Fig. 1 is a flowchart illustrating a method for adjusting a wind resistance of a vehicle according to an exemplary embodiment, so as to solve a technical problem in the related art that a vehicle cannot achieve a wind resistance reduction effect in the whole driving process. As shown in fig. 1, the method for adjusting the wind resistance of the vehicle includes:
and S11, adjusting the shape of the windward structure of the vehicle body for multiple times to change the wind resistance coefficient of the vehicle body.
And S12, acquiring the wind resistance of the vehicle subjected to the adjustment of the shape of the windward structure each time.
And S13, correspondingly adjusting the windward structural shape of the vehicle body according to the minimum value of the wind resistance acquired for multiple times.
In the related art, in order to reduce the wind resistance of a vehicle when the vehicle runs at a high speed, the modeling structure of the vehicle is only optimally designed to achieve the purpose of reducing the wind resistance, but in the running process of the vehicle, the wind resistance changes at any time along with the change of external conditions, so that the purpose of reducing the wind resistance cannot be achieved in the whole running process of the vehicle.
In order to solve the above problem, first, step S11 is performed to adjust the windward structural shape of the vehicle body a plurality of times to change the wind resistance coefficient of the vehicle body. The windward structure of the vehicle body can comprise structures such as a vehicle rearview mirror, a flow guide cover, a front bumper, an engine compartment, a flow guide plate and a luggage rack which are arranged on the windward side of the vehicle.
The calculation formula of the wind resistance F is as follows:
ρ is the air density; s is the projection area in the advancing direction of the vehicle; v is the vehicle speed; and C is a wind resistance coefficient and is related to the windward area of the object, the smoothness degree of the object and the overall shape.
The wind resistance coefficient is related to the shape of an object and is in direct proportion to the wind resistance, namely the wind resistance coefficient can be adjusted by adjusting the shape of the windward structure of the vehicle body, and the size of the wind resistance can also be adjusted.
For example, for a vehicle rearview mirror, the wind resistance coefficient of the vehicle rearview mirror can be changed by adjusting the shape of the rear shell of the vehicle rearview mirror; for the front bumper, a push rod can be arranged to be connected with the front bumper and the vehicle body, for example, push rods are respectively arranged on the upper part of the front bumper and the lower part of the front bumper, and the push rod pushes and pulls the front bumper to change the inclination angle of the front bumper, so as to change the wind resistance coefficient of the front bumper; for the air guide sleeve, a connecting rod can be arranged to be connected with the air guide sleeve and the vehicle body, the height and the inclination angle of the air guide sleeve can be adjusted by pushing the connecting rod, and the wind resistance coefficient of the vehicle body can be further changed; the windward side structures of other vehicle bodies such as an engine compartment, a guide plate, a luggage rack and the like can be movably connected with the vehicle bodies, and the wind resistance coefficient of the vehicle bodies can be changed by adjusting the positions and angles of the windward side structures.
After the wind resistance coefficient of the vehicle body is changed, step S12 is executed to obtain the magnitude of wind resistance received by the vehicle after the windward structural shape is adjusted each time. The windward side of the windward structure can be provided with a wind resistance sensor, and the wind resistance of the windward structure after the shape of the windward structure is adjusted every time is obtained through the wind resistance sensor. In step S11, the number of times of adjustment may be two, three, or four times, and the disclosure is not limited in this respect, as long as each time of adjustment, the wind resistance after each adjustment of the windward structure is obtained by the wind resistance sensor.
After the wind resistance of the vehicle subjected to each adjustment of the windward structural shape is acquired, step S13 is executed to correspondingly adjust the windward structural shape of the vehicle body according to the minimum value of the wind resistance acquired multiple times. For example, the wind resistance coefficient of the windward structure of the vehicle body is adjusted for three times, and the wind resistance after the adjustment for three times is recorded through a wind resistance sensor; and adjusting the windward structure according to the shape of the windward structure corresponding to the minimum wind resistance by comparing the size of the wind resistance adjusted for three times, so that the shape of the windward structure is the same as the shape corresponding to the minimum wind resistance.
Optionally, before adjusting the shape of the windward structure of the vehicle body multiple times to change the wind resistance coefficient of the vehicle body, the method further comprises: the method includes the steps of acquiring the speed of a vehicle, and confirming that a range section where the speed of the vehicle is located changes after the speed of the vehicle is acquired. The vehicle speed of the vehicle can be obtained by a speed sensor arranged on the vehicle, or by reading the vehicle speed information displayed on an instrument panel. The range section in which the vehicle speed is located may be set artificially, for example, the vehicle speed greater than 0 and less than or equal to 50km/h is defined as the same range section, the vehicle speed greater than 50km/h and less than or equal to 120km/h is defined as the same range section, and the vehicle speed greater than 120km/h is defined as the same range section.
When the vehicle speed enters a range section which is larger than 0 and smaller than or equal to 50km/h from a standstill, steps S12, S13 and S14 are executed, and after step S14 is executed, if the vehicle speed is always in the range section which is larger than 0 and smaller than or equal to 50km/h, the step of adjusting the windward structure of the vehicle body is not executed any more. If the vehicle speed enters the range section which is greater than 0 and less than or equal to 50km/h to the range section which is greater than 50km/h and less than or equal to 120km/h, the steps S12, S13 and S14 are executed, and after the step S14 is executed, if the vehicle speed is always in the range section which is greater than 50km/h and less than or equal to 120km/h, the step of adjusting the windward structural shape of the vehicle body is not executed.
The windward structure of the vehicle body is adjusted according to the windward structure shape corresponding to the minimum windward resistance, so that the windward structure of the vehicle body is adjusted to achieve the effect of reducing the windward resistance of the vehicle body, and the technical problem that the vehicle cannot achieve the windward resistance reducing effect in the whole running process in the related technology is solved.
