Referring specifically to fig. 2, fig. 2 is a flow chart illustrating an overspeed prevention method for a vehicle according to an exemplary embodiment of the present application. The overspeed preventing method at least comprises S210 to S230, and is described in detail as follows:
s210: a first speed and a first position of the vehicle are obtained, and a second position of the overspeed identification point and a speed threshold value of the overspeed identification point are obtained.
In this embodiment, the first vehicle speed and the first position may be regarded as real-time vehicle speed information and real-time position information of the vehicle during driving.
The overspeed identification point can be regarded as a position point of overspeed photographing of the vehicle on a driving path, and the second position and a speed threshold value of the overspeed identification point can be obtained through a navigation map.
In practical application, the overspeed identification point used for calculation in the overspeed prevention method of the vehicle is one overspeed identification point closest to the first position during running of the vehicle, and the speed threshold value is a specified maximum running speed.
S220: a first vehicle speed control parameter is obtained during driving of the vehicle from the first location to the second location based on the first location, the second location, the first vehicle speed, and the speed threshold.
In this embodiment, the values of the first vehicle speed and the speed threshold may be compared first, if the first vehicle speed is less than or equal to the speed threshold, the current time point may not be subjected to subsequent operations, and if the first vehicle speed is greater than the speed threshold, it may be further determined whether to perform subsequent operations for obtaining the first vehicle speed control parameter.
Specifically, if the first vehicle speed is greater than the speed threshold, calculating a first time parameter of the vehicle based on the driving distance, the first vehicle speed and the speed threshold; if the first time parameter is greater than or equal to the preset time interval value, S220 is executed.
The preset time interval value can be set based on the first vehicle speed of the current vehicle to control the distance threshold value, and can also be set through experience parameters.
Specifically, the calculation of the first time parameter t1 is: t1=s1/(V1-V0), where S1 is the driving distance, V1 is the first vehicle speed, and V0 is the speed threshold.
In an embodiment, the driving distance may be calculated by: mapping the first position and the second position to a navigation map, and correspondingly obtaining a first map position and a second map position on the navigation map; the driving distance is obtained based on the road between the first map position and the second map position on the navigation map.

S230: the speed of the vehicle is controlled based on the first speed control parameter such that the second speed of the vehicle at the second location is not greater than the speed threshold.
In this embodiment, the first vehicle speed control parameter may be regarded as a vehicle speed corresponding to different time points in the process of driving the vehicle from the first position to the second position, so that the running speed of the vehicle may be controlled so that the second vehicle speed of the vehicle at the second position is not greater than the speed threshold.
Of course, in some embodiments, the speed of the vehicle is controlled based on the first speed control parameter, so that the second speed of the vehicle when the preset driving distance exists between the vehicle and the second position is not greater than the speed threshold, and therefore the speed of the vehicle can be not greater than the speed threshold before the second position, driving safety is further improved, and overspeed violation risk is reduced.
According to the overspeed prevention method for the vehicle, through the real-time position and the vehicle speed information of the vehicle and the position information of the overspeed identification point, the first vehicle speed control parameter in the process of driving the vehicle from the first position to the second position is calculated, so that the vehicle speed before the vehicle drives to the second position is controlled, the vehicle speed can not be larger than the specified speed when passing through the overspeed photographing position, the driving safety of the vehicle is ensured, and the violations are reduced.
In another exemplary embodiment of the present application, the manner of acquiring the first vehicle speed control parameter is described in detail, as shown in fig. 3, and in S220 in the overspeed protection method shown in fig. 2, S310 to S330 are further included, which is described in detail as follows:
s310: a first relation is established with time as an independent variable and the speed of the vehicle as a dependent variable.
In this embodiment, the first relation represents a change relation between a vehicle speed and time during driving of the vehicle from the first position to the second position.
The first relation is represented in the coordinate system and can be regarded as time is horizontal axis/X axis, and vehicle speed is vertical axis/Y axis, as shown in the first relation structure diagram of FIG. 4.
A certain time in fig. 4 can be regarded as a time corresponding to the first vehicle speed, V At the current time That is, at is the first time, Δt is the time taken for the vehicle to travel from the first position to the second position, and V-limit value is the speed threshold.
S320: and adjusting the first relation based on the relation between the preset vehicle speed and the deceleration to obtain an adjusted first relation.
The preset vehicle speed and deceleration in the embodiment can be obtained according to empirical parameters, namely, the corresponding values of the vehicle speed are different, if the vehicle speed is too fast, the passenger in the vehicle can be uncomfortable, so that the preset vehicle speed and the different vehicle speeds in the deceleration correspond to the values of the deceleration, and the deceleration of the vehicle is larger or smaller than the corresponding values under the corresponding vehicle speeds.
FIG. 5 is a block diagram of a preset vehicle speed and deceleration according to one embodiment, wherein the vehicle speed is on the abscissa/X-axis and the deceleration is on the ordinate/Y-axis, and the point (30,2.5) indicates that the deceleration should be no greater than 2.5m/s at a vehicle speed of 30km/h (kilometers per hour) 2 (km/sec), point (150,2) indicates that at a vehicle speed of 150km/h (km/h), the deceleration should be no greater than 2m/s 2 (kilometers per square second).
In the embodiment, a vehicle speed to be analyzed and a corresponding deceleration to be analyzed which correspond to respective variables are obtained based on a first relational expression; acquiring a target deceleration corresponding to the vehicle speed to be analyzed based on a relation between a preset vehicle speed and the deceleration; and adjusting the deceleration to be analyzed based on the target deceleration to obtain an adjusted first relation.
Specifically, in the adjusted first relational expression, the deceleration at the time point of the different vehicle speeds does not exceed the preset vehicle speed and the deceleration specified in the deceleration at the corresponding vehicle speed.
The deceleration in the first relation may be obtained by deriving the first relation or fig. 4.
S330: and determining a first vehicle speed control parameter based on the adjusted first relation.
In this embodiment, the first relation characterizes the vehicle speed at each moment after the first speed, so that the vehicle speed of the vehicle at each moment can be obtained, and the moment and the corresponding vehicle speed are used as the first vehicle speed control parameters to control the vehicle speed of the vehicle.
In some embodiments, when the speed of the vehicle is controlled in S230, an obstacle is detected, and the vehicle may be located on an object (such as a car, a bicycle, a pedestrian, etc.) that moves slowly during the running process of the vehicle, so as to ensure driving safety, a second vehicle control parameter is acquired, and control of the vehicle is performed.
Specifically, if an obstacle is detected in the process of driving the vehicle from the first position to the second position, acquiring a third position of the obstacle and an obstacle speed; acquiring a second vehicle speed control parameter in the process of driving the vehicle from the first position to the third position based on the first position, the first vehicle speed, the third position and the obstacle speed; the speed of the vehicle is controlled based on the second vehicle speed control parameter such that the third speed of the vehicle at the third position is not greater than the obstacle speed.
In this embodiment, the second vehicle speed control parameter is obtained in the same manner as the first vehicle speed control parameter, except that the speed threshold used in obtaining the first vehicle speed control parameter is changed to the obstacle speed.
Of course, when calculating the second vehicle control parameter, the second time parameter may also be acquired based on the acquisition mode of the first time parameter, so as to determine whether the second vehicle speed control parameter needs to be acquired.
It should be noted that the processing procedures of the first time parameter, the second vehicle speed control parameter, and the like are similar to the processing procedures of the first time parameter and the first vehicle speed control parameter, and only the data related to the overspeed identification point is replaced by the data related to the obstacle.
