Description

A warning system for inner wheel difference of a large electric bus

technical field

The utility model belongs to the technical field of vehicle operation safety, in particular to an inner wheel difference early warning system of a large electric passenger car.

Background technique

With the continuous increase of the world's population and the sharp shortage of oil resources, large electric buses are more and more favored by people, but the hidden danger of inner wheel difference will cause a lot of property loss or personal injury to people. The inner wheel difference will cause the driver to have a visual blind spot when the large electric bus is turning. If you only pay attention to the front wheel passing and forget the inner wheel difference during driving, it will cause the rear wheel to drive off the road or collide with other objects. Consequences of the collision.

At present, there are relatively few inner wheel differential warning systems installed on large electric buses, and some of them only rely on the rearview mirror to observe the situation in the inner wheel differential dangerous area. The inner wheel difference warning system is single, which increases the danger of passing pedestrians and vehicles.

And the existing inner wheel difference early warning system mainly plays a reminding role to the driver, but does not play any warning function for passing pedestrians and vehicles located in the inner wheel difference dangerous area, so there is a problem of insufficient two-way reminder; moreover the driver It is necessary to lower your head frequently to observe the liquid crystal display installed in the cab, which will obviously distract the driver's attention, thereby causing great danger. In addition, the start of some early warning systems requires that the driver toggle the steering switch, which depends on the driver's driving habits to a certain extent. Sometimes the driver does not toggle the steering switch when turning, so no early warning will be generated at all. Therefore, the traditional Whether the early warning system is effective or not has a lot of human factors; for the early warning system equipped with LED lights, due to the relatively strong daytime light, its projection area is not obvious, so the role of the early warning device cannot be fully utilized.

Utility model content

In view of the above problems, this utility model is proposed. Therefore, the purpose of this utility model is to provide an inner wheel differential early warning system for large electric buses, improve the safety of the turning process, and ensure that pedestrians and vehicles are not threatened by inner wheel differential hazards.

The system designed by the utility model is composed of a main early warning device and an auxiliary early warning device. The main early warning device is composed of a head-up display, a laser radar detector, a camera and a corner sensor; Buzzer composition.

The camera and the LED lights at night are each a pair, and they are symmetrically installed at the lower end of the rearview mirror of the electric bus; the buzzers are symmetrically installed at the ends of both sides of the rear of the car; The two sides of the vehicle body of the large electric passenger car; the voice prompter is installed in the cab of the electric passenger car; the corner sensor is installed on the steering column of the large electric passenger car.

The head-up display is installed on the front windshield of a large electric bus, and the driver can see the important information he needs without looking down, reducing driver fatigue, avoiding interruption of attention and loss of grasp of state awareness.

The laser radar detectors are evenly distributed on both sides of the body of the large electric bus. There are 8 laser radar detectors on each side of the body, and there is a certain gap between them. Its detection area is larger than the dangerous area of the inner wheel difference, which improves the accuracy rate of the inner wheel difference early warning device.

The steering angle sensor is installed on the steering shaft of the vehicle to judge the turning direction of the vehicle, and calculates the corresponding inner wheel differential dangerous area according to the angle of the steering shaft, and its signal output terminal is connected with the laser radar detector and the camera.

In addition, the nighttime LED does not work during the day, but illuminates the dangerous area at night. On the one hand, the driver can clearly see the situation in the dangerous area of the inner wheel difference, and on the other hand, it reminds pedestrians and vehicles to pay attention to the inner wheel difference. The buzzer in the auxiliary early warning device reminds nearby pedestrians or passing vehicles to actively avoid in time, especially plays a vital role for pedestrians or vehicles already in the dangerous area; the voice prompter in the cab reminds the driver to pay attention Observe dangerous areas, alarm in various ways and remind drivers, pedestrians and vehicles in two directions.

The utility model is suitable for large electric passenger cars with a length of 12M. Appropriate improvements can be made on other large electric passenger cars. The arrangement distance of the laser radar detectors on both sides of the vehicle body can be adjusted appropriately.

detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

What the utility model shows is a kind of inner wheel differential warning system of a large electric bus, as shown in Figure 1, it is a comparatively optimized implementation scheme, installed in a large electric bus with a length of 12M. The devices installed on the left and right of the vehicle body are symmetrical, and the mutual cooperation of various instruments in the system effectively reduces the risk caused by the inner wheel difference.

Figure 3 shows the flow chart of the system embodiment. Combined with Figure 4, the angle sensor installed on the steering shaft of the vehicle judges the turning direction of the vehicle, and calculates the corresponding dangerous area of inner wheel difference according to the angle of the steering shaft. As shown in Figure 1 and Figure 2, the vehicle is turning towards When turning right, the rotation angle sensor installed on the steering shaft of the vehicle starts to work, and calculates the corresponding inner wheel difference dangerous area 6 (composed of the right rear wheel track 8 and the right front wheel track 5 of the vehicle when turning right), at this time the main warning device Start to work: The signal input terminals of the lidar detectors evenly distributed on the right side of the vehicle body and the camera installed at the lower end of the rearview mirror receive the signal of the vehicle turning right from the corner sensor, and start to work. The laser radar detector on the right sends a detection signal to detect whether there are pedestrians and vehicles passing through the rear end of the vehicle body and the inner wheel differential danger area 6; at the same time, the camera detects the inner wheel differential dangerous area 6, and the detection area is slightly Greater than the inner wheel difference danger zone 6, the two transmit the signal to the head-up display. The driver observes the situation in the dangerous area of the inner wheel difference from the head-up display, and when there is no obstacle in the dangerous area of the inner wheel difference, the large electric bus turns safely.

When there is an obstacle in the dangerous area of the inner wheel gap displayed on the head-up display, the auxiliary warning device starts to work: on the one hand, the voice prompter in the driving room sends out a reminder to make the driver drive carefully and pay attention to pedestrians and vehicles; on the other hand, it is installed in the The buzzer at the rear of the car sounds to warn pedestrians and vehicles to avoid being threatened by the dangerous area of the inner wheel differential and realize two-way reminder; at night, the night LED lights illuminate the dangerous area of the inner wheel differential, The size of the illuminated area is consistent with the size of the camera detection area.
