Description

Technical Field

[0001] The present invention relates to the technical field of data processing, and in particular to a method and device for batch processing of intelligent terminal data. Background Art

[0002] When new energy vehicles are driving on urban roads, frequent starts and stops will lead to reduced energy recovery efficiency, increased battery load fluctuations, and significantly shortened cruising range. In existing technologies, although smart terminals can monitor vehicle data, they lack the following functions: deep coordination with traffic signal systems, and cannot give dynamic speed adjustment suggestions based on the timing of traffic lights ahead, resulting in an increase in the number of starts and stops at intersections, affecting the vehicle's cruising range. Summary of the invention

[0003] In view of this, the purpose of the present invention is to propose a batch processing method and device for intelligent terminal data to solve the problem that it is currently impossible to give suggestions for dynamically adjusting the vehicle speed according to the timing of the traffic lights ahead, resulting in an increase in the number of starts and stops of the vehicle at the intersection, affecting the vehicle's cruising range.

[0004] Based on the above purpose, the present invention provides a method for batch processing of intelligent terminal data, comprising: S1: Detect the distance between the vehicle and the traffic light; S2: When it is detected that the distance between the vehicle and the traffic light is less than 300 meters, obtain the first speed of the vehicle, obtain the traffic light data, calculate the time t when the vehicle passes the traffic light at the first speed, and adjust the speed of the vehicle based on the time t, the first speed and the traffic light data in the following manner: S21: When the remaining time of the green light is ≥ time t, a prompt is issued to maintain the current first speed and pass at a constant speed; S22: when the remaining time of the green light is less than the time t, calculating the second speed of the vehicle that just passes the intersection with the remaining time of the green light, determining whether the second speed exceeds the maximum speed limit, and if not, issuing a prompt to accelerate the first speed to the second speed, and if exceeding, issuing a prompt to control the first speed to slow down to a stop; S23: When the remaining time of the red light is less than or equal to time t, a prompt is issued to maintain the current first speed and pass at a constant speed; S24: When the remaining time at the red light is greater than time t, calculate the third vehicle speed for passing the intersection with the remaining time at the red light, and determine whether the third vehicle speed is greater than 20 km / h. If so, issue a prompt to decelerate the first vehicle speed to the third speed; if not, issue a prompt to control the first vehicle speed to decelerate to a stop.

[0005] Optionally, the method further includes: When the remaining time of the green light is ≥ time t, and the current first speed is maintained to pass at a constant speed, when it is detected that the speed of the vehicle ahead is lower than the first speed, a prompt is issued to adjust the first speed to synchronize with the speed of the vehicle ahead, and it is determined whether the synchronized speed can pass the traffic light. If it is determined that it can, a prompt is issued to pass the traffic light at the synchronized speed. If it is determined that it cannot, a prompt is issued to suggest changing lanes or controlling the synchronized speed to slow down to a stop; When the remaining time of the green light is less than the time t, the second speed of the vehicle just passing the intersection with the remaining time of the green light is calculated, and it is determined whether the second speed exceeds the maximum speed limit. At the same time, it is determined whether there is a vehicle ahead with a speed lower than the second speed. If it does not exceed the maximum speed limit and there is no vehicle ahead with a speed lower than the second speed, a prompt is issued to accelerate the first speed to the second speed. If it does not exceed the maximum speed limit and there is a vehicle ahead with a speed lower than the second speed, a prompt is issued to suggest changing lanes or control the speed of the synchronized vehicle to slow down to a stop. When the remaining time of the red light is ≤ time t, and a vehicle ahead is detected with a speed lower than the first speed, a prompt is issued that is synchronized with the speed of the vehicle ahead; When the remaining time at the red light is greater than time t, the third speed for the vehicle to pass the intersection with the remaining time at the red light is calculated, and it is determined whether the third speed is greater than 20km / h. If so, a prompt is issued to decelerate the first speed to the third speed. When it is detected that the speed of the vehicle ahead is less than 20km / h, a prompt is issued that is synchronized with the speed of the vehicle ahead.

[0006] Optionally, the method further includes: obtaining the volume level Y when the vehicle speed is greater than 40 km / h and the real-time vehicle speed, and adjusting the volume level based on the following method: The vehicle speed range is 0-20km / h, and the volume is adjusted to 0.5Y; The vehicle speed range is 20-40km / h, and the volume is adjusted to 0.7Y; The vehicle speed range is >40km / h, and the volume is adjusted to Y.

[0007] Optionally, the method further includes: obtaining the real-time vehicle speed, and adjusting the screen brightness of the vehicle-mounted tablet based on the following method: The vehicle speed range is 0-30km / h, and the screen brightness of the vehicle-mounted tablet is adjusted to 70% brightness; When the vehicle speed is >30km / h, the screen brightness of the vehicle tablet is adjusted to 30%.

[0008] Optionally, the method also includes, when the vehicle-mounted tablet is used for navigation, when the navigation module detects that the road needs to be changed, controlling the screen brightness of the vehicle-mounted tablet to be adjusted to 70% brightness; after the road is changed and the vehicle speed range is >30km / h, controlling the screen brightness of the vehicle-mounted tablet to be adjusted to 30% brightness.

[0009] Optionally, acquiring traffic light data includes receiving traffic light data sent by a roadside unit through a vehicle-mounted unit.

[0010] Optionally, obtaining the traffic light data includes determining the vehicle's own position through a positioning system, sending a request for traffic light data to a cloud storing the traffic light data, and receiving the traffic light data sent from the cloud.

[0011] Based on the same invention, the present invention also provides a device for a batch processing method of intelligent terminal data, comprising: Distance detection module: used to detect the distance between the vehicle and the traffic light; The vehicle speed adjustment module is used to obtain the first vehicle speed of the vehicle and the traffic light data when it is detected that the distance between the vehicle and the traffic light is less than 300 meters, calculate the time t when the vehicle passes the traffic light at the first speed, and adjust the vehicle speed in the following manner based on the time t, the first vehicle speed and the traffic light data: When the remaining time of the green light is greater than or equal to time t, a prompt is given to maintain the current first speed and pass at a constant speed; When the remaining time of the green light is less than the time t, the second speed of the vehicle that just passes the intersection with the remaining time of the green light is calculated, and it is determined whether the second speed exceeds the maximum speed limit. If it does not exceed the maximum speed limit, a prompt is issued to accelerate the first speed to the second speed; if it exceeds the maximum speed limit, a prompt is issued to control the first speed to slow down to a stop; When the remaining time of the red light is ≤ time t, a prompt is issued to maintain the current first speed and pass at a constant speed; When the remaining time at the red light is greater than time t, the third vehicle speed for passing the intersection with the remaining time at the red light is calculated, and it is determined whether the third vehicle speed is greater than 20 km / h. If so, a prompt is issued to decelerate the first vehicle speed to the third speed; if not, a prompt is issued to control the first vehicle speed to decelerate to a stop.

[0012] When the method is used for data processing, the distance between the vehicle and the traffic light is first detected. When the distance between the vehicle and the traffic light is detected to be less than 300 meters, the speed of the vehicle at this time is obtained, and the speed at this time is used as the first speed. Then, the traffic light data is obtained, and the time t for the vehicle to pass the traffic light at the first speed is calculated. When the remaining time of the green light is ≥ time t, a prompt is issued to keep the current first speed and pass at a uniform speed, which can be sent to the driver by voice, and the speed can be maintained to pass the traffic light, so that the driver's judgment can be reduced, and there is no need to accelerate or decelerate, which can reduce power consumption; when the remaining time of the green light is < time t, the second speed of the green light remaining time just passing the intersection is calculated, and it is judged whether the second speed exceeds the maximum speed limit. If not, a prompt is issued to accelerate the first speed to the second speed. If it exceeds the maximum speed limit, a prompt is issued to control the first speed to slow down to stop. In this way, if the maximum speed limit is not exceeded, the vehicle can pass without stopping. If it exceeds, the driver can be reminded to slow down to stop, so as to avoid the driver's misjudgment and speeding. When the remaining time at the red light is ≤ time t, a prompt is issued to maintain the current first speed and pass through at a constant speed. When the remaining time at the red light is ≤ time t, it means that the light has turned green before the vehicle reaches the intersection, so the current first speed and pass through at a constant speed. When the remaining time at the red light is > time t, the third speed that is just enough to pass through the intersection is calculated, and it is determined whether the third speed is greater than 20km / h. If so, a prompt is issued to decelerate the first speed to the third speed. By decelerating to the third speed, the time to reach the intersection can be extended, so that the red light can be turned green when the vehicle arrives at the intersection. In this way, the vehicle does not need to stop and start again, thus saving power. If not, a prompt is issued to decelerate the first speed to a stop.

[0013] From the above, it can be seen that this method can reduce the number of times the vehicle starts and stops at traffic lights, thereby saving power and extending the vehicle's cruising range. At the same time, it can reduce the occurrence of driver misjudgment, help the driver judge whether to pass the traffic lights in time, and improve driving safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0018] like Figure 1 As shown, a batch processing method for intelligent terminal data includes: S1: Detect the distance between the vehicle and the traffic light. The distance between the vehicle and the traffic light can be obtained through the high-precision map and the positioning module. S2: When it is detected that the distance between the vehicle and the traffic light is less than 300 meters, the first speed of the vehicle is obtained, the traffic light data is obtained, and the time t when the vehicle passes the traffic light at the first speed is calculated. For example, when the vehicle is 300 meters away from the traffic light and the first speed of the vehicle is 54 km / h, the time t when the vehicle passes the traffic light at the first speed is calculated to be 20 seconds. Based on the time t, the first speed and the traffic light data, the speed of the vehicle is adjusted in the following manner: S21: When the remaining time of the green light is ≥ time t, a prompt is issued to maintain the current first speed and pass at a constant speed; S22: when the remaining time of the green light is less than the time t, calculating the second speed of the vehicle that just passes the intersection with the remaining time of the green light, determining whether the second speed exceeds the maximum speed limit, and if not, issuing a prompt to accelerate the first speed to the second speed, and if exceeding, issuing a prompt to control the first speed to slow down to a stop; S23: When the remaining time of the red light is less than or equal to time t, a prompt is issued to maintain the current first speed and pass at a constant speed; S24: When the remaining time at the red light is greater than time t, calculate the third vehicle speed for passing the intersection with the remaining time at the red light, and determine whether the third vehicle speed is greater than 20 km / h. If so, issue a prompt to decelerate the first vehicle speed to the third speed; if not, issue a prompt to control the first vehicle speed to decelerate to a stop.

[0019] When the method is used for data processing, the distance between the vehicle and the traffic light is first detected. When it is detected that the distance between the vehicle and the traffic light is less than 300 meters, the speed of the vehicle at this time is obtained, and the speed at this time is used as the first speed. Then the traffic light data is obtained, and the time t for the vehicle to pass the traffic light at the first speed is calculated. When the remaining time of the green light is ≥ time t, a prompt is issued to maintain the current first speed and pass at a constant speed, which can be sent to the driver by voice. The speed can be maintained to pass the traffic light, which can reduce the driver's judgment and does not need to accelerate or decelerate, which can reduce power consumption. When the remaining time of the green light is < time t, the second speed of the green light remaining time just enough to pass the intersection is calculated, and it is determined whether the second speed exceeds the maximum speed limit. If not, a prompt is issued to accelerate the first speed to the second speed. For example, the distance between the vehicle and the traffic light is: 150 meters, the current speed (first speed): 40 km / h, the remaining time of the green light: 10 seconds, the road speed limit: 60 km / h, the calculation time , judge: remaining time of green light (10 seconds) < time t (13.5 seconds), calculate the second vehicle speed: , the second vehicle speed (54km / h) ≤ the speed limit (60km / h), and a prompt is issued that "it is recommended to accelerate to 54km / h to pass the intersection within the green light time". In actual work, the time required for acceleration can also be calculated through the existing algorithm, so that the calculation can be more accurate. If the maximum speed limit is exceeded, a prompt is issued to control the first vehicle speed to slow down to a stop. In this way, if the maximum speed limit is not exceeded, the vehicle can pass without stopping. If the maximum speed limit is exceeded, the driver can be reminded to slow down to a stop to avoid the driver's misjudgment and speeding. When the remaining time at the red light is ≤ time t, a prompt is issued to maintain the current first speed and pass through at a constant speed. When the remaining time at the red light is ≤ time t, it means that the light has turned green before the vehicle reaches the intersection, so the current first speed and pass through at a constant speed. When the remaining time at the red light is > time t, the third speed that is just enough to pass through the intersection is calculated, and it is determined whether the third speed is greater than 20km / h. If so, a prompt is issued to decelerate the first speed to the third speed. By decelerating to the third speed, the time to reach the intersection can be extended, so that the red light can be turned green when the vehicle arrives at the intersection. In this way, the vehicle does not need to stop and start again, thus saving power. If not, a prompt is issued to decelerate the first speed to a stop.

[0020] From the above, it can be seen that this method can reduce the number of times the vehicle starts and stops at traffic lights, thereby saving power and extending the vehicle's cruising range. At the same time, it can reduce the occurrence of driver misjudgment, help the driver judge whether to pass the traffic lights in time, and improve driving safety.

[0021] Before passing the traffic light, there may be a slow-moving vehicle ahead. In order to further improve the method, in some embodiments, the method further includes: When the remaining time of the green light is ≥ time t, and the current first speed is maintained to pass at a constant speed, when it is detected that the speed of the vehicle in front (the speed of the vehicle in front can be detected by the vehicle-mounted radar) is lower than the first speed, a prompt is issued to adjust the first speed to synchronize with the speed of the vehicle in front, reminding the driver to slow down and avoid rear-end collision, and judge whether the synchronized speed can pass the traffic light. If it is judged that it can, a prompt is issued to pass the traffic light at the synchronized speed. If it is judged that it cannot, a prompt is issued to suggest changing lanes or controlling the synchronized speed to slow down to stop. The driver makes a judgment based on the on-site conditions. When there are conditions for changing lanes, he can choose to change lanes and then pass the traffic light, so there is no need to start and stop the vehicle. When there are no conditions for changing lanes, he still chooses to slow down to stop and wait for the next green light; When the remaining time of the green light is less than the time t, the second speed of the vehicle that just passes the intersection with the remaining time of the green light is calculated, and it is determined whether the second speed exceeds the maximum speed limit. At the same time, it is determined whether there is a vehicle ahead with a speed lower than the second speed. If it does not exceed the maximum speed limit and there is no vehicle ahead with a speed lower than the second speed, a prompt is issued to accelerate the first speed to the second speed. If it does not exceed the maximum speed limit and there is a vehicle ahead with a speed lower than the second speed, it means that the lane cannot pass the current green light within the maximum speed limit, and a prompt is issued to suggest changing lanes or control the synchronized speed to slow down to stop. The driver makes a judgment based on the on-site conditions. When there are conditions for changing lanes, he can choose to change lanes and then pass the traffic light, so there is no need to start and stop the vehicle. When there are no conditions for changing lanes, he still chooses to slow down to stop and wait for the next green light. When the remaining time of the red light is ≤ time t, and a vehicle ahead is detected with a speed lower than the first speed, a prompt is issued that is synchronized with the speed of the vehicle ahead; When the remaining time at the red light is greater than time t, the third speed for the vehicle to pass the intersection with the remaining time at the red light is calculated, and it is determined whether the third speed is greater than 20km / h. If so, a prompt is issued to decelerate the first speed to the third speed. When it is detected that the speed of the vehicle ahead is less than 20km / h, a prompt is issued that is synchronized with the speed of the vehicle ahead.

[0022] From the above, it can be seen that when a slow-moving vehicle appears in front, this method can process the data and issue different improvements according to different situations to help the driver make judgments. It can reduce the number of vehicle starts and stops, extend the vehicle's cruising range, and at the same time reduce the occurrence of driver misjudgment, thereby improving driving safety.

[0023] In some embodiments, the method further includes: obtaining the volume level Y when the vehicle speed is greater than 40 km / h and the real-time vehicle speed, and adjusting the volume level based on the following method: The vehicle speed range is 0-20km / h, and the volume is adjusted to 0.5Y; The vehicle speed range is 20-40km / h, and the volume is adjusted to 0.7Y; The vehicle speed range is >40km / h, and the volume is adjusted to Y.

[0024] When working, the vehicle speed can be obtained through the vehicle speed detection module, and the vehicle speed and current volume can be received through the volume management module. The volume management module is based on the adjustment rules: The vehicle speed range is 0-20km / h, and the volume is adjusted to 0.5Y; The vehicle speed range is 20-40km / h, and the volume is adjusted to 0.7Y; The vehicle speed range is >40km / h, the volume is adjusted to Y, the volume is adjusted, and the adjusted volume is sent to the volume output module.

[0025] The higher the vehicle speed, the louder the wind noise and tire noise. Therefore, the higher the vehicle speed, the higher the volume should be so that the people in the car can hear it. When the vehicle speed decreases, the volume needs to be lowered to prevent discomfort caused by excessive volume. In this method, the volume can be automatically adjusted according to the vehicle speed so that the volume can better meet the needs of the people in the car. At the same time, when the vehicle speed decreases, reducing the volume can also reduce the power consumption in the car.

[0026] In some embodiments, the method further includes: obtaining the real-time vehicle speed, and adjusting the screen brightness of the vehicle-mounted tablet based on the following method: The vehicle speed range is 0-30km / h, and the screen brightness of the vehicle-mounted tablet is adjusted to 70% brightness; When the vehicle speed is >30km / h, the screen brightness of the vehicle tablet is adjusted to 30%.

[0027] When the vehicle speed is >30km / h, the driver's main focus is on driving. At this time, the car tablet is not actively used very often, so the screen brightness of the car tablet can be controlled to 30% brightness, which can further save electricity consumption in the car. When the vehicle speed range is 0-30km / h, for example, when the vehicle speed is 0 when waiting for a traffic light, the number of times the car tablet is actively used increases. The screen brightness of the car tablet is controlled to be adjusted to 70% brightness for the convenience of the driver. When the screen brightness of the car tablet is 30% brightness, after detecting contact with the touch, the screen brightness of the car tablet is controlled to be adjusted to 70% brightness for the convenience of people in the car.

[0028] In some embodiments, the method also includes, when the vehicle-mounted tablet is used for navigation, when the navigation module detects that the road needs to be changed, controlling the screen brightness of the vehicle-mounted tablet to be adjusted to 70% brightness to facilitate the driver to observe the navigation interface; after the road change is completed and the vehicle speed range is >30km / h, controlling the screen brightness of the vehicle-mounted tablet to be adjusted to 30% brightness to reduce power consumption in the car.

[0029] In some embodiments, acquiring the traffic light data includes receiving the traffic light data sent by the roadside unit through the on-board unit.

[0030] Vehicles interact with roadside units (RSUs) through wireless communication technologies (such as DSRC or C-V2X) to obtain real-time phase information (red light / green light) and remaining time of traffic lights. Implementation method: Roadside unit (RSU): Installed at intersections, collects and broadcasts traffic light controller data in real time. On-board unit (OBU): Receives traffic light information broadcast by RSU and passes it to the vehicle control system.

[0031] Advantages: strong real-time performance (delay < 100ms), high data accuracy (directly from the traffic signal controller).

[0032] In other embodiments, the obtaining of traffic light data includes determining the vehicle's own position through a positioning system, sending a request for traffic light data to a cloud storing traffic light data, and receiving traffic light data sent from the cloud.

[0033] The vehicle connects to the cloud platform through the 4G / 5G network to obtain the traffic light timing data of the intersection ahead. Implementation method: The traffic signal controller uploads the traffic light data to the cloud. The vehicle determines its own position through GPS positioning and requests the traffic light information of the intersection ahead.

[0034] Advantages: Wide coverage (not limited by RSU deployment), and can obtain forecast data for multiple future traffic light cycles.

[0035] In order to further implement the present invention, the present invention also provides a device for a batch processing method of intelligent terminal data, comprising: Distance detection module: used to detect the distance between the vehicle and the traffic light; The vehicle speed adjustment module is used to obtain the first vehicle speed of the vehicle and the traffic light data when it is detected that the distance between the vehicle and the traffic light is less than 300 meters, calculate the time t when the vehicle passes the traffic light at the first speed, and adjust the vehicle speed in the following manner based on the time t, the first vehicle speed and the traffic light data: When the remaining time of the green light is greater than or equal to time t, a prompt is given to maintain the current first speed and pass at a constant speed; When the remaining time of the green light is less than the time t, the second speed of the vehicle that just passes the intersection with the remaining time of the green light is calculated, and it is determined whether the second speed exceeds the maximum speed limit. If it does not exceed the maximum speed limit, a prompt is issued to accelerate the first speed to the second speed; if it exceeds the maximum speed limit, a prompt is issued to control the first speed to slow down to a stop; When the remaining time of the red light is ≤ time t, a prompt is issued to maintain the current first speed and pass at a constant speed; When the remaining time at the red light is greater than time t, the third vehicle speed for passing the intersection with the remaining time at the red light is calculated, and it is determined whether the third vehicle speed is greater than 20 km / h. If so, a prompt is issued to decelerate the first vehicle speed to the third speed; if not, a prompt is issued to control the first vehicle speed to decelerate to a stop.

[0036] From the above, it can be seen that the device can reduce the number of times the vehicle starts and stops at traffic lights, thereby saving electricity and extending the vehicle's cruising range. At the same time, it can reduce the occurrence of driver misjudgment, help the driver judge whether to pass the traffic lights in time, and improve driving safety.

[0037] It should be understood by those skilled in the art that the discussion of any of the above embodiments is merely illustrative and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples. Under the concept of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the above aspects of the present invention, which are not provided in detail for the sake of simplicity.

The method for batch processing of intelligent terminal data according to claim 1, characterized in that: The obtaining of traffic light data includes determining the vehicle's own position through a positioning system, sending a request for traffic light data to a cloud storing traffic light data, and receiving the traffic light data sent by the cloud.

8. A device for executing the batch processing method of intelligent terminal data according to claim 1, characterized in that: include: Distance detection module: used to detect the distance between the vehicle and the traffic light; The vehicle speed adjustment module is used to obtain the first vehicle speed of the vehicle and the traffic light data when it is detected that the distance between the vehicle and the traffic light is less than 300 meters, calculate the time t when the vehicle passes the traffic light at the first speed, and adjust the vehicle speed in the following manner based on the time t, the first vehicle speed and the traffic light data: When the remaining time of the green light is greater than or equal to time t, a prompt is given to maintain the current first speed and pass at a constant speed; When the remaining time of the green light is less than the time t, the second speed of the vehicle that just passes the intersection with the remaining time of the green light is calculated, and it is determined whether the second speed exceeds the maximum speed limit. If it does not exceed the maximum speed limit, a prompt is issued to accelerate the first speed to the second speed; if it exceeds the maximum speed limit, a prompt is issued to control the first speed to slow down to a stop; When the remaining time of the red light is ≤ time t, a prompt is issued to maintain the current first speed and pass at a constant speed; When the remaining time at the red light is greater than time t, the third vehicle speed for passing the intersection with the remaining time at the red light is calculated, and it is determined whether the third vehicle speed is greater than 20 km / h. If so, a prompt is issued to decelerate the first vehicle speed to the third speed; if not, a prompt is issued to control the first vehicle speed to decelerate to a stop.
