The execution subject of the route switching method based on unmanned driving provided by the embodiment of the disclosure is the route switching device based on unmanned driving, and the route switching device is integrated in an unmanned automobile.
Fig. 1 is a flowchart of a route switching method based on unmanned driving according to an embodiment of the present disclosure.
In a first aspect, an embodiment of the present disclosure provides a route switching method based on unmanned driving, and with reference to fig. 1, the method includes:
and S1, collecting the user state and judging whether the user is in a sleep state. When it is determined that the user is in the sleep state, step S2 is executed.
Specifically, when a user enters the unmanned vehicle, the user sets a starting point and a destination on the vehicle-mounted navigation, the vehicle-mounted navigation provides a plurality of driving routes for the user to select, then selects one of the driving routes, starts the unmanned vehicle, and the unmanned vehicle starts according to the driving route selected by the user on the vehicle-mounted navigation. And when the user starts the unmanned automobile, the route switching device is also started, so that the acquisition module, such as a camera, in the route switching device acquires the current state of the user in real time, and transmits the acquired state information to the judgment module of the route switching device so as to judge whether the user is in a sleep state. Specifically, when the state of the user is judged to be the eye closing state within the preset time, the user is judged to be in the sleep state.
And S2, acquiring the current position information and the destination position information of the user, and planning an alternative driving route which can be driven to the destination.
In this step, the road switching device acquires the current position information of the user located by the vehicle navigation and the destination information input into the vehicle navigation by the user, and plans an alternative driving route which can be driven to the destination through the vehicle navigation.
It should be noted that, the embodiments of the present disclosure provide a route switching method based on unmanned driving, so that at least two routes from the current position to the destination are obtained in this step, that is, at least two alternative driving routes are obtained.
And S3, selecting one of the alternative driving routes as a current driving route according to preset conditions, and controlling the unmanned automobile to switch to the current driving route for driving.
In this step, the preset condition may be a user road condition, and specifically, the road condition may include at least one of a traffic light quantity, a traffic flow, a curve quantity, a curve radius, and a road flatness. Specifically, when the number of the red lights and the number of the green lights are taken as the preset conditions, an alternative driving route with the least number of the traffic lights can be selected as the current driving route in the step, so that the comfort level of the user is improved; when the traffic flow is used as a preset condition, an alternative driving route with the least traffic flow can be selected as a current driving route in the step, so that the comfort level of a user is improved; when the number of curves is taken as a preset condition, an alternative driving route with the least number of curves can be selected as a current driving route in the step, so that the comfort level of a user is improved; when the radius of the curve is taken as a preset condition, an alternative driving route with the maximum radius of the curve can be selected as a current driving route in the step, so that the comfort level of a user is improved; when the road flatness is used as a preset condition, an alternative driving route with the most flat road flatness can be selected as the current driving route in the step, so that the comfort level of the user is improved. Of course, if the number of the traffic lights in the multiple alternative driving routes is the same and the number of the traffic lights is the minimum, it is determined which of the other conditions is better, and the alternative driving route is selected as the current route. If the preset conditions in the embodiment of the present disclosure are multiple conditions among the number of green lights, the traffic flow, the number of curves, the radius of the curve, and the flatness of the road surface, a weight may be set for each condition, and the current driving route may be selected from the alternative driving routes according to the calculated result.
The route switching method based on unmanned driving provided by the embodiment of the disclosure can automatically switch a route with higher comfort level after a user sleeps in an unmanned automobile, so that the user experience can be greatly improved.
Fig. 2 is a flowchart of step S3 of the unmanned-based route switching method according to the embodiment of the present disclosure.
In some embodiments, referring to fig. 2, step S3 may specifically include the following steps:
and S31, obtaining the comfort level and the running time of each alternative running route according to the road condition of each alternative running route.
Specifically, the road condition of the alternative driving route in this step includes: at least one of traffic light quantity, traffic flow, curve quantity, curve radius and road surface evenness. If the road condition only includes the traffic lights, the number of the traffic lights represents the comfort level of the alternative driving route, that is, the less the number of the traffic lights of the alternative driving route, the higher the comfort level. At the same time, the travel time of each alternative route needs to be calculated at this step.
And S32, acquiring the alternative driving routes meeting the time threshold according to the driving time of each alternative driving route and the driving time from the current position to the destination in the original driving route.
Specifically, the time threshold in the embodiment of the present disclosure refers to: the user can set the range of the increased duration of the travel time of the alternative travel route from the current position to the travel time of the destination in the original travel route when using the route switching device. For example, the travel time of the alternative travel route is increased by 10%, 20%, 30%, etc. from the travel time of the current location to the destination in the original travel route. In this step, according to a preset time threshold, an alternative driving route meeting the time threshold is acquired.
And S33, taking the one with the highest comfort level in the alternative driving routes meeting the time threshold value as the current driving route, and controlling the unmanned automobile to switch to the current driving route for driving.
That is, in this step, the current travel route is obtained from the candidate travel route that satisfies the time threshold value acquired in step S32 and the comfort level of the several candidate routes acquired in step S31.
Fig. 3 is a flowchart of step S4 of the unmanned-based route switching method according to the embodiment of the present disclosure.
In some embodiments, referring to fig. 3, the unmanned-based route switching method, after step S3, may further include: and S4, when the user does not arrive at the destination yet and the user is judged to be in the waking state from the sleeping state, controlling the vehicle-mounted display screen to display the current position information and the current driving route and prompting the user whether to switch other routes.
That is to say, after the unmanned vehicle is switched to the current route and does not reach the destination, the acquisition module of the route switching device detects that the user is in the wake-up state from the sleep state, controls the vehicle-mounted display screen to display the current position information and the current driving route of the vehicle, and displays an icon for inquiring whether the user switches other routes, so that the user can switch to other routes by himself or herself.
Fig. 4 is a flowchart of step S5 of the route switching method based on unmanned driving according to the embodiment of the present disclosure.
In some embodiments, referring to fig. 4, the unmanned-based route switching method, after step S3, may further include: and S5, when the user arrives at the destination and is judged to be in the sleep state, sending a wake-up signal to the user to wake up the user.
That is to say, when the user arrives at the destination, the acquisition module of the route switching device determines that the user is still in the sleep state, and at this time, the user can send a wake-up signal to wake up the user. The wake-up signal may be an audio signal, such as playing music, or a vibration signal, such as a vibration module provided on the user's seat to send a vibration signal.
