The core of the application is to provide a control method, a device and a medium of the electric car safety protection device, so as to prevent the interference of environmental factors such as illumination, lines and the like on the operation of the electric car, thereby improving the safety of the electric car.
Unlike the closed independent right of a metro train, the metro train (such as a tram or a trolley bus) shares the right of way with social vehicles, pedestrians and the like at a level crossing, the automatic driving technology of the metro train cannot be directly used, and a driver cannot timely handle an emergency caused by not following the traffic rules. According to related statistical data, more than 70% of accidents of the tramcar occur at a level crossing, at present, a vehicle-mounted camera and a vehicle-mounted radar are generally used for detecting obstacles in front of a vehicle, and the tramcar is controlled to run according to detection results, but because the vehicle-mounted camera and the vehicle-mounted radar are installed in a fixed area on the vehicle, the detection results are easily affected by factors such as illumination, weather and tramcar running lines, and the obstacles cannot be detected in time. In order to solve this problem, the present application provides an electric car safety guard, including: the environment detection sensor at least comprises a camera and a radar; the environment detection sensor is connected with the intersection to generate barrier information according to the traffic condition at the intersection; the controller is connected with the environment detection sensor to acquire the obstacle information and send a deceleration instruction to the electric car to control the electric car to brake when the obstacle information meets the preset condition.

In order that those skilled in the art will better understand the disclosure, the following detailed description is given with reference to the accompanying drawings.
Fig. 1 is a structural diagram of an electric vehicle safety protection device according to an embodiment of the present application, and as shown in fig. 1, the device includes:

the environment detection sensor is connected with the intersection to generate barrier information according to the traffic condition at the intersection;

In specific implementation, the environment detection sensor at least comprises a camera and a radar, wherein the camera is used for acquiring obstacle information in the detection area, and the obstacles comprise vehicles, pedestrians and the like. In a specific implementation, the camera is used for detecting whether an obstacle exists in the detection area, and the radar is used for detecting specific position and speed information of the obstacle. When the obstacle information is detected, the controller acquires the obstacle information sent by the camera and determines the running track of the obstacle in a future period of time by combining the radar detection information sent by the radar, so that whether the electric car is dangerous when passing through the intersection is judged, and if the electric car is dangerous, a deceleration instruction or a braking instruction is sent to the electric car in time.
It is understood that the number of the controllers may be only one, or may be plural. When only one controller exists, the controller can be arranged at the intersection or in the electric car; when there are a plurality of controllers, one of the controllers may be provided at the intersection and the other one in the electric train. Further, the controller provided in the tram may use the central control unit CCU with which the tram has been configured or configure the control module separately. In consideration of the fact that controllers arranged at the intersections have high compatibility with conditions such as volume and energy, high-performance processors can be selected, and the same controller can be used for controlling environment detection sensors at a plurality of intersections.
In a specific implementation, data transmission between the controllers can be performed through a vehicle-to-vehicle Communication module based on Dedicated Short Range Communication (DSRC) or a Communication carrier radar with a Communication function.
The application provides an electric car safety device includes: the environment detection sensor at least comprises a camera and a radar; the environment detection sensor is connected with the intersection to generate barrier information according to the traffic condition at the intersection; the controller is connected with the environment detection sensor to acquire the obstacle information and send a deceleration instruction to the electric car to control the electric car to brake when the obstacle information meets the preset condition. Therefore, according to the technical scheme provided by the application, the obstacle information near the intersection is acquired by arranging the environment detection sensor at the intersection, so that the situation that the trolley bus cannot timely detect the obstacle information at the intersection due to the fact that special environment factors at the intersection are caused is prevented, and the safety of the trolley bus is improved.
In the concrete implementation, in order to improve the stability and reliability in the running process of the electric train, the method is based on the embodiment. The controller comprises a first controller and a second controller;
the first controller is arranged at the intersection, the second controller is arranged in the electric car, and the first controller and the second controller are communicated through a DSRC communication unit.
As a preferred embodiment, the first controller is disposed at an intersection, and the second controller is disposed in an electric train, wherein the radar and the sensor of the environment detection sensor are disposed in four directions of a level crossing, 1 detection radar and 1 camera sensor are disposed in each direction, and a detection range (for example, within a range of 5 meters from the center of the intersection) is determined according to the actual situation of the intersection. The radar, the camera and the first controller can be connected through optical fibers or can be connected through Ethernet.
In specific implementation, a camera arranged at a level crossing selects a camera with a detection distance larger than 30 meters, detects obstacles within a range of 30 meters along a track and 5 meters vertical to the track, and sends a detection result to a ground control unit through an Ethernet; the radar equipment sends radar speed measurement information to the ground control unit through the CAN bus. The second controller obtains early warning reminding information from the Vehicle-Vehicle communication module through a CAN Bus or an Ethernet Bus, and sends the early warning reminding information to an electric Vehicle-mounted controller through a Multifunctional Vehicle Bus (MVB) or the CAN Bus to control the electric Vehicle to decelerate, or sends a deceleration instruction to a driver to control the electric Vehicle to decelerate.
In the embodiment, the obstacle information and the trolley information of the ground are respectively processed by the first controller and the second controller, so that the trolley stability and reliability are improved.
Fig. 2 is a flowchart of a control method for an electric car safety device according to an embodiment of the present disclosure, and as shown in fig. 2, the method is applied to an electric car safety device including an environment detection sensor and a controller, the environment detection sensor is connected to a road junction, and the controller is connected to the environment detection sensor; the method comprises the following steps:
s10: obtaining barrier information sent by an environment monitoring sensor, wherein the environment monitoring sensor is arranged at the intersection;
s11: judging whether the barrier information meets a preset condition or not;
s12: and if the preset condition is met, sending a deceleration instruction to the electric car to control the electric car to brake.
Wherein, obtain the barrier information that environmental monitoring sensor sent and include:
when the obstacle is detected to exist in the detection area, video information and radar detection information collected by a camera are obtained; and determining the movement information of the obstacle according to the video information and the radar detection information. Wherein, judging whether the obstacle information meets the preset condition comprises: acquiring trolley parameter information and trolley motion information to determine the trolley safety distance; and if the distance between the obstacle and the electric car is greater than the safety distance of the electric car, determining that the preset condition is met.
In a specific implementation, a range perpendicular to the track direction (the track boundary and a distance along the track perpendicular direction) is used as the detection area, and the distance along the track direction directly uses the maximum detection distance of the camera. When the video information acquired by the camera is used for dynamically identifying the video in the detection area; when it is determined that obstacles such as pedestrians or vehicles exist in the detection area, the first controller controls the radar to measure the speed of the obstacles. The ground radar sensor detects the relative distance between the tramcar and the obstacle (namely the distance between the tramcar and the radar position of the intersection) and the relative speed between the tramcar and the obstacle in the track direction in real time.
The first controller generates a braking command according to the distance and the speed of the tramcar detected by the radar when the existence of an obstacle in the detection area is detected and the moving speed of the obstacle is greater than a threshold speed according to pre-stored tramcar parameter information (comprising a service braking deceleration and an emergency braking deceleration capacity). According to different situations, the braking instruction may include a multi-stage braking instruction such as early warning information, braking request information, emergency braking request information and the like generated according to the braking capability of the train. For example: according to the reaction time of the driver, the braking capacity of the vehicle sets three distance thresholds: the system comprises a reminding distance, a safe braking distance and an emergency braking distance, wherein the safe braking distance is a value obtained by multiplying the maximum service braking deceleration by a certain proportion at the highest running speed, and the emergency braking distance is a value obtained during emergency braking at the highest running speed. It should be noted that the reminding distance, the safety braking distance and the emergency braking distance are train reminding distances when the barrier is stationary, and when the barrier is in a moving state, the distances need to be correspondingly adjusted according to the moving direction and the moving speed of the barrier.
It can be understood that, in the running process of the train, frequent emergency braking can affect the riding experience of passengers and cause energy waste, and in order to solve the problem, the train can select different braking acceleration according to the relative distance between the obstacle and the train and the running speed of the train. Furthermore, when the barrier is a pedestrian or a vehicle, the position of the barrier can be predicted according to the motion track of the barrier collected by the camera, so that the first controller arranged at the ground intersection can conveniently select the corresponding braking acceleration of the train, and the experience of a user during train braking is improved. For example, when a pedestrian and a train move forward to a level crossing along different roads simultaneously, the speed of the train is V, and the speed of the pedestrian is 5m/s, it can be determined that the reminding distance of the train is 200m, the deceleration distance is 150m, the safety braking distance is 120m, and the emergency braking distance is 70m according to the speed of the pedestrian and the performance parameters of the train; then:
when the distance between the train and the level crossing is less than the reminding distance (200 m) and greater than the deceleration distance (150 m), the first controller sends the distance to the train network system through the communication unitAn alarm signal to operate a train network system display and an alarm device to remind a driver of paying attention to prevent a traffic accident caused by the driver not noticing a pedestrian; when the distance between the train and the level crossing is smaller than the deceleration distance (150 m) and larger than the safe braking distance (120 m), the first controller sends a deceleration signal to the train network system through the communication unit to control the train to brake, so that a driver can control the speed of the train in time, and the riding experience of passengers is prevented from being influenced by emergency braking; the usual braking deceleration of the train being V 2 /2S Wherein S is the distance between the train and the level crossing; it is to be noted that this braking deceleration corresponds to the performance parameters and the load of the train;
when the distance between the train and the level crossing is less than the safe braking distance (120 m) and greater than the emergency braking distance (70 m), the first controller sends a braking signal to a train network system through the communication unit so as to control the train to brake by adopting the maximum service braking deceleration;
when the distance between the train and the level crossing is less than the emergency braking distance (70 m), the first controller sends a braking signal to the train network system through the communication unit, and in order to ensure the safety of the train, the first controller sends the emergency braking signal to the train network system through the communication unit so as to control the emergency braking of the train.
The application provides a control method of a safety protection device of an electric car, which is applied to the following steps: the trolley safety protection device comprises an environment detection sensor and a controller, wherein the environment detection sensor at least comprises a camera and a radar; the environment detection sensor is connected with the intersection to generate barrier information according to the traffic condition at the intersection; the controller is connected with the environment detection sensor to acquire the obstacle information and send a deceleration instruction to the electric car to control the electric car to brake when the obstacle information meets the preset condition. Therefore, according to the technical scheme provided by the application, the obstacle information near the intersection is acquired by arranging the environment detection sensor at the intersection, so that the situation that the trolley bus cannot timely detect the obstacle information at the intersection due to the fact that special environment factors at the intersection are caused is prevented, and the safety of the trolley bus is improved.
In a specific implementation, after the deceleration command is sent to the electric train, if the electric train does not decelerate in time, a traffic accident may occur. In order to solve the problem, in the above embodiment, after the step of sending the deceleration command to the electric vehicle to control braking of the electric vehicle, the method for controlling an electric vehicle safety protection device further includes:
judging whether the electric car decelerates within a threshold time;
if the electric train is not decelerated, an alarm is sent to a manager.
In a specific implementation, an electric vehicle-mounted controller (CCU) obtains traction and braking information operated by a driver through an electric vehicle bus, and if the CCU sends a braking request prompt for exceeding a threshold time (for example, 3 s), and still continuously receives a braking request sent by a ground Control Unit, and meanwhile obtains that the driver does not apply corresponding braking operation from an MVB or a CAN bus, the CCU actively applies a braking level to implement braking, and meanwhile sends an alarm to a manager to protect the safety of the electric vehicle operation.
