Abstract
The display prompter for large goods train and semi-trailer steering meniscus area consists of camera, display, steering sensor of steering machine, speed sensor and signal processor. The image of the external scene of the automobile driving shot by the camera is displayed on the display through the signal processor, the left and right steering signals generated by the steering sensor of the steering gear are analyzed and calculated through the signal processor, the left and right meniscus area graphic signals which correspond to the steering angle and direction and are matched with the external scene are generated and are superposed and displayed on the display, and the signal processor can generate the complete meniscus area graphic signals. The number and the installation position of the cameras are the best scheme according to the characteristics of the type of the vehicle through experiments, and the shape of the meniscus area graph is determined and generated through the relationship between the turning angle and the turning radius difference of the type of the vehicle (whether a semi-trailer is available), the number of axles and the wheelbase through experiments and further in combination with the algorithm of a signal processor.
Description
The technical field is as follows:
the invention relates to the technical field of transportation and electronic information
Background art:
due to the fact that the wheelbase of a front axle and a rear axle of a semitrailer and other passenger and truck with longer body is longer, when the semitrailer and other passenger and truck with longer body turn, the front wheel and the rear wheel have larger turning radius difference, and the radius difference enables the semitrailer and other passenger and truck with longer body to form a meniscus area on the driving track of the semitrailer when the semitrailer and other passenger and truck turn. In particular, in the semitrailer, because the relative positions of the head and the rear hanging part are not fixed, when the semitrailer turns, the observation angle of the rear view reflector of the head can change, the meniscus area can not be observed, and becomes a vision blind area, so the meniscus area is also called as a dead meniscus area. The 'death meniscus region' of semitrailers and other trucks with longer bodies in China causes a lot of traffic accidents every year, and the accidents are frequently caused when the vehicles run at low speed and turn at large angles, the turning radius difference of front wheels and rear wheels is large, the 'death meniscus region' is large in area and high in risk, and under the condition, the accidents are mostly at intersections with dense urban personnel, so that serious losses are caused to the lives and properties of people.
The invention content is as follows:
in order to reduce and avoid traffic accidents caused by 'death meniscus', the display prompter for steering the large-sized passenger-truck and the semitrailer to the meniscus is designed and invented to help drivers of the semitrailer and other passenger-truck with longer vehicle bodies to observe and judge the 'death meniscus', so that the accidents are reduced, and the loss of lives and property of people is reduced. The display prompter for large goods train and semi-trailer steering meniscus area consists of camera, display, direction sensor, speed sensor and signal processor. The image of the external scene of the automobile is shot by the camera and displayed on the display through the signal processor, and the left and right steering signals generated by the direction machine sensor are analyzed and calculated through the signal processor to generate left or right meniscus area graphic signals which correspond to the steering angle and direction and are matched with the external scene and are superposed and displayed on the display. The 'death meniscus' traffic accident mainly occurs when the vehicle is driven at low speed to turn at a large angle, the vehicle speed sensor detects the vehicle speed, the signal processor automatically starts the meniscus display when the vehicle speed is lower than a certain numerical value to help a driver to observe and judge the safety of the 'death meniscus' condition, the vehicle speed is higher than a certain numerical value to be automatically closed so as not to interfere the normal driving of the driver, and the function can be manually switched on and off. The number and the installation position of the cameras are the best scheme according to the characteristics of the type of the vehicle through experiments, and the shape of the meniscus area graph is determined and generated through the relationship between the turning angle and the turning radius difference of the type of the vehicle (whether a semi-trailer is available or not), the number of axles and the wheelbase through experiments and further in combination with the algorithm of a signal processor.
Description of the drawings:
the attached drawing of the specification is a schematic diagram formed by the principle of a display prompter for steering meniscus areas of trucks and semitrailers.
In the figure, 1: camera, 2: steering sensor of steering gear, 3: speed sensor, 4: the signal processor sends the driving outdoor scene image signals acquired by the camera to the display for displaying, acquires the left and right steering signals of the steering sensor of the steering gear, performs analysis and calculation, generates left or right meniscus area graphic signals corresponding to the steering angle and direction and matched with the outdoor scene, and sends the graphic signals to the display for superposition and display 5: display, which may be an interactive touch screen display, 6: vehicle turning meniscus trajectory pattern generated by the signal processor, 7: the display displays the exterior view of the vehicle.
The specific implementation mode is as follows:
the display prompter for large goods train and semi-trailer steering meniscus area consists of camera, display, steering sensor of steering machine, speed sensor and signal processor. The camera shoots the outside scene image of the automobile driving, the image is displayed on the display through the signal processor, the left and right steering signals generated by the steering sensor of the steering gear are analyzed and calculated through the signal processor, the left and right meniscus area graphic signals which correspond to the steering angle and direction and are matched with the outside scene are generated and are superposed and displayed on the display, the signal processor can generate a complete meniscus area graphic signal, and also can only generate an arc graphic signal (close to one side of the center of the meniscus area graphic) outside the automobile in the image, and the dead meniscus area prompting function can be also played. The 'death meniscus' traffic accident mainly occurs when the vehicle is driven at low speed to turn at a large angle, the vehicle speed sensor detects the vehicle speed, the signal processor automatically starts the meniscus display when the vehicle speed is lower than a certain numerical value to help a driver to observe and judge the safety of the 'death meniscus' condition, the vehicle speed is higher than a certain numerical value to be automatically closed so as not to interfere the normal driving of the driver, and the function can be manually switched on and off. The number and the installation position of the cameras are the best scheme according to the characteristics of the type of the vehicle through experiments, and the shape of the meniscus area graph is determined and generated through the relationship between the turning angle and the turning radius difference of the type of the vehicle (whether a semi-trailer is available), the number of axles and the wheelbase through experiments and further in combination with the algorithm of a signal processor.
