[0077] The specific embodiments of the present application have been shown in the above-described drawings, and will be described in more detail hereinafter. These drawings and the written description are not intended to restrict the scope of the present application concept in any way, but to illustrate the present application concept to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0078] The exemplary embodiments will be described in detail herein with reference to the attached drawings. The same numbers are used in different drawings to represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all the implementations consistent with the present application. Instead, they only represent a number of devices and methods consistent with some aspects of the present application, as detailed in the appended claims.

[0079] Currently, a vehicle can determine the obstacle in front and / or rear through radar or ultrasonic wave to prompt the driver of the existence of the obstacle, and the driver autonomously performs corresponding operation. However, the driver cannot be provided with the actual scheme of operation, such as acceleration, deceleration or lane change, and needs to perform corresponding operation according to the driving experience.

[0080] When the vehicle is in rain, fog or night driving environment, the driver is difficult to accurately determine the safety distance between the front vehicle or rear vehicle and the current vehicle through the human eye, so that the driving safety is low.

[0081] Therefore, the present application provides a vehicle control method, the current vehicle can obtain the multiple speeds of the nearby vehicle (such as the front vehicle and / or the rear vehicle) in the area where the current vehicle is located, and the multiple distances between the nearby vehicle and the current vehicle, to determine the driving trend of the nearby vehicle, and then output the driving operation prompt information according to the driving trend, to provide the reference for the actual operation of the driver, and not to depend on the driving experience and driving skill of the driver, so that the driving safety of the vehicle can be further improved even in rain, fog or night.

[0082] In order to facilitate understanding, the application scenarios to which the embodiments of the present application are applied are described below in combination with the examples of Figure 1 .

[0083] Figure 1 The schematic diagram of one application scenario to which the present application is applied is shown in Figure 1 , which includes a rear vehicle 101, a current vehicle 102 and a front vehicle 103.

[0084] When the current vehicle 102 detects the existence of the rear vehicle 101 and / or the front vehicle 103 during driving, the current vehicle 102 can obtain the multiple vehicle information of the rear vehicle 101 and / or the front vehicle 103, i.e. the multiple speeds of the rear vehicle 101 and the multiple distances between the rear vehicle 101 and the current vehicle 102, and / or the multiple speeds of the front vehicle 103 and the multiple distances between the front vehicle 103 and the current vehicle 102, and then can determine the driving trend of the rear vehicle 101 and / or the front vehicle 103 according to the multiple vehicle information, so that the current vehicle 102 outputs the prompt information according to the driving trend to prompt the driver to perform corresponding operation.

[0085] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail in the following specific embodiments. The following specific embodiments can exist independently, or can be combined with each other, and the same or similar concepts or processes can not be described again in some embodiments. The embodiments of the present application will be described below in combination with the drawings.

[0086] Figure 2A flowchart of a vehicle control method provided by Embodiment One of the present application is shown in FIG. 1. The method can be executed by a current vehicle or a vehicle control device installed in the current vehicle. The device can be a chip, a chip module, an integrated development environment (IDE), or the like. In the following, the current vehicle is taken as an example, and reference is made to FIG. 1. Figure 2 The method includes the following steps.

[0087] S201. Obtain vehicle information of a nearby vehicle of the current vehicle in one or more detection periods.

[0088] During driving, if the current vehicle detects that there is a nearby vehicle in the area where the current vehicle is located, for example, a vehicle in front of the current vehicle (hereinafter referred to as a front vehicle) and / or a vehicle behind the current vehicle (hereinafter referred to as a rear vehicle), the current vehicle can obtain vehicle information of the nearby vehicle in one or more detection periods.

[0089] Each vehicle information is detected in one detection period, and the vehicle information includes a first speed of the nearby vehicle and a first distance between the nearby vehicle and the current vehicle.

[0090] For example, the time interval between the detection periods can be a first preset time length, for example, 10 seconds. That is, the current vehicle obtains vehicle information of the nearby vehicle every first preset time length, so that the current vehicle can determine the driving trend of the nearby vehicle according to the obtained vehicle information.

[0091] In one possible implementation, since the speed of the nearby vehicle and the distance between the nearby vehicle and the current vehicle can change in real time during driving, the current vehicle can detect the speed of the nearby vehicle and the distance between the nearby vehicle and the current vehicle multiple times in each detection period, and then determine the speed of the nearby vehicle and the distance between the nearby vehicle and the current vehicle in the detection period according to the multiple detected speeds and distances.

[0092] In another possible implementation, the current vehicle can shorten the time interval between the detection periods, and detect the speed of the nearby vehicle and the distance between the nearby vehicle and the current vehicle once in each detection period. The detected speed and distance are taken as the speed of the nearby vehicle and the distance between the nearby vehicle and the current vehicle in the detection period.

[0093] S202. Determine a driving trend of the nearby vehicle according to the multiple vehicle information.

[0094] After obtaining the multiple vehicle information in the multiple detection periods, the current vehicle can determine the driving trend of the nearby vehicle according to the multiple vehicle information.

[0095] For example, the driving trend of the nearby vehicle (e.g., the rear vehicle) can be that the nearby vehicle is accelerating and shortening the safety distance between the current vehicle and the nearby vehicle, or the driving trend of the nearby vehicle (e.g., the front vehicle) can be that the nearby vehicle is decelerating and shortening the safety distance between the current vehicle and the nearby vehicle.

[0096] S203, generating the prompt information according to the driving trend, and outputting the prompt information, the prompt information including one or more of acceleration, deceleration, and lane changing.

[0097] After determining the driving trend of the nearby vehicle, the current vehicle can generate the prompt information according to the driving trend, the prompt information including one or more of specific actual operations, such as acceleration, deceleration, and lane changing.

[0098] After generating the prompt information, the current vehicle can output the prompt information to the driver in the following ways, so that the driver can perform the corresponding driving operation according to the prompt information to ensure driving safety:

[0099] Method 1: The current vehicle can output the prompt information by voice broadcast to prompt the driver to perform the corresponding operation.

[0100] Method 2: The current vehicle can display the prompt information on the control panel of the vehicle to prompt the driver to perform the corresponding operation.

[0101] The application does not limit the way the current vehicle outputs the prompt information, and the prompt information can also be output in other ways.

[0102] It can be understood that the prompt information can also include the driving trend of the nearby vehicle, for example, the front vehicle is decelerating and shortening the safety distance between the current vehicle and the front vehicle, so that the driver can clearly understand the driving situation of the nearby vehicle.

[0103] In this embodiment, the current vehicle obtains vehicle information of the nearby vehicle in one or more detection periods, wherein the vehicle information includes a first speed of the nearby vehicle and a first distance between the nearby vehicle and the current vehicle, and the nearby vehicle includes a front vehicle and / or a rear vehicle. Then, according to the vehicle information, the driving trend of the nearby vehicle is determined, and the prompt information is generated according to the driving trend, and the prompt information is output, the prompt information including one or more of acceleration, deceleration, and lane changing, providing a reference for the actual operation of the driver, not relying on the driving experience and driving technology of the driver, and further improving the driving safety of the vehicle even in rainy and foggy weather or at night.

[0104] Next, another vehicle control method provided by the application is described in Embodiment 2.

[0105] Figure 3 Another flowchart of a vehicle control method is provided for Embodiment Two of the present application. The method can be performed by a current vehicle or a vehicle control device provided in the current vehicle. The device can be a chip, a chip module, an IDE, or the like. The following takes the current vehicle as an example, and reference is made to Figure 3 The method includes the following steps:

[0106] S301. Obtain vehicle information of a nearby vehicle of the current vehicle in one or more detection periods.

[0107] When it is detected that there is a nearby vehicle in the area where the current vehicle is located, the current vehicle can obtain the vehicle information of the nearby vehicle in any detection period by the following method:

[0108] The current vehicle obtains N second speeds of the nearby vehicle in the detection period through a detection device, and then determines a first speed of the nearby vehicle in the detection period according to the N second speeds. The current vehicle also obtains a third speed of the current vehicle and device information of the detection device, and determines a first distance between the current vehicle and the nearby vehicle in the detection period according to the N second speeds, the third speed, and the device information. N is an integer greater than or equal to 1.

[0109] Specifically, the N second speeds are obtained by measuring the speed of the nearby vehicle multiple times by the current vehicle in the detection period. The current vehicle determines the first speed of the nearby vehicle in the detection period according to the N second speeds. For example, the first speed can be obtained by formula (1).

[0110]

[0111] Wherein, v is the first speed, v1, v2, …, v N are the N second speeds.

[0112] Optionally, when the detection device is an ultrasonic wave or a radar, the device information includes the transmission speed of the ultrasonic wave or the radar. For example, the transmission speed of the radar is generally 300000 km / h (kilometers per hour), that is, 83333.3334 m / s (meters per second), and the transmission speed of the ultrasonic wave is generally 340 m / s. The relative distance between objects can be calculated by using the propagation time and speed according to the ultrasonic wave or radar ranging principle.

[0113] In this way, the current vehicle can obtain N time lengths consumed by the detection device to detect N second speeds, and then determine N second distances according to the N second speeds, the third speed, the transmission speed and the N time lengths. For example, the second distance can be determined by formula (2). Then the average of the N second distances can be determined as the first distance between the nearby vehicle and the current vehicle in the detection period, for example, formula (3).

[0114]

[0115] wherein i is 1, 2, …, N, S i is the ith second distance, T i is the ith time length, v i is the ith second speed, and c is the transmission speed.

[0116]

[0117] wherein S is the first speed, s1, s2, …, s N are the N second distances.

[0118] S302, obtain the vehicle type of the nearby vehicle, the vehicle type being a rear vehicle type or a front vehicle type.

[0119] The current vehicle can determine the vehicle type of the nearby vehicle, i.e., determine whether the nearby vehicle is a front vehicle type or a rear vehicle type, to accurately determine the driving trend of the nearby vehicle according to the vehicle type.

[0120] S303, determine the speed change trend according to the plurality of first speeds.

[0121] The current vehicle can determine the speed change trend according to the size of the plurality of first speeds in the order of detection. If the plurality of first speeds gradually decrease (i.e., decrease), it is determined that the speed change trend is decelerating, and if the plurality of first speeds gradually increase (i.e., increase), it is determined that the speed change trend is accelerating.

[0122] It can be understood that the size of the plurality of first speeds does not change in the form of increasing or decreasing, for example, the plurality of first speeds are: speed 1, speed 2, speed 3, …, speed n, the size of speed 1, speed 2, and speed 3 changes in the form of increasing, the size of speed 3, speed 4, and speed 6 changes in the form of decreasing, and the size of speed 7, …, speed n changes in the form of increasing. Therefore, from the overall change trend, the change trend of the plurality of first speeds is increasing.

[0123] S304, determine the distance change trend according to the plurality of first distances.

[0124] The current vehicle can determine, according to the sizes of the plurality of first distances, the distance change trend as being decelerated if the plurality of first distances gradually decrease (i.e., decrease in a step-by-step manner), or as being accelerated if the plurality of first distances gradually increase (i.e., increase in a step-by-step manner).

[0125] If the sizes of the plurality of first distances do not change in the form of increasing or decreasing, reference can be made to S303, which will not be described herein again.

[0126] S305, determining the driving trend according to the vehicle type, the speed change trend, and the distance change trend.

[0127] Optionally, when the vehicle type of the nearby vehicle is the rear vehicle type, i.e., the nearby vehicle is a rear vehicle of the region where the current vehicle is located, if the speed change trend of the nearby vehicle is an increasing trend and the distance change trend is a decreasing trend, it can be determined that the driving trend is: accelerating and shortening the safety distance between the current vehicle and the nearby vehicle.

[0128] Optionally, when the vehicle type of the nearby vehicle is the front vehicle type, i.e., the nearby vehicle is a front vehicle of the region where the current vehicle is located, if the speed change trend is a decreasing trend and the distance change trend is a decreasing trend, it can be determined that the driving trend is: decelerating and shortening the safety distance between the current vehicle and the nearby vehicle.

[0129] S306, generating the prompt information according to the driving trend and outputting the prompt information.

[0130] After determining the driving trend of the nearby vehicle, the current vehicle can generate the prompt information according to the driving trend and output the prompt information to prompt the driver to perform corresponding operations.

[0131] Specifically, if the nearby vehicle is a rear vehicle and the driving trend is: accelerating and shortening the safety distance between the current vehicle and the nearby vehicle, the generated prompt information is to accelerate within the speed limit or change lanes.

[0132] If the nearby vehicle is a front vehicle and the driving trend is: decelerating and shortening the safety distance between the current vehicle and the nearby vehicle, the generated prompt information is to decelerate or change lanes.

[0133] In the embodiment, vehicle information of a nearby vehicle of a current vehicle in one or more detection periods is acquired, the vehicle information including a first speed of the nearby vehicle and a first distance between the nearby vehicle and the current vehicle, the nearby vehicle including a front vehicle and / or a rear vehicle. A vehicle type of the nearby vehicle is acquired, the vehicle type being a rear vehicle type or a front vehicle type. A speed change trend is determined according to the plurality of first speeds, a distance change trend is determined according to the plurality of first distances, a driving trend is determined according to the vehicle type, the speed change trend and the distance change trend, a prompt information is generated according to the driving trend, and the prompt information is output, the prompt information including one or more of acceleration, deceleration and lane change, so as to provide a reference for actual operation of the driver, and the driving safety of the vehicle can be further improved even in rainy and foggy weather or at night.
