Description

Signal prompting method of driving control information of automatic driving

Technical Field

The invention relates to the technical field of intelligent transportation, automatic driving and intelligent automobiles.

Background

In the world, the existing overall urban morphology, from the space structure to the use division, from the vehicles to the transportation system, all have historically and naturally evolved to date from the civilized morphology of farming and the former industry, the formation of the space structure and the use division is caused by the extensive extension of homogenization in urban housing and industrial and commercial scale concentration, the formation of the vehicles and the transportation system is caused by the customary evolution of the horse vehicle architecture and the small town living transportation morphology, and the large urban diseases are continuously spread and increasingly serious. Compared with the modern large-scale urban civilization with intensive high volume ratio after the industrial era and the automatic digital intelligent technical means which is leap forward after the information era, the current urban form lacks the cooperation innovation with hierarchy transition, the urban system architecture design with order guidance and efficiency optimization is relatively lagged, and the concept and the technology of the cooperation elements in the aspects of the traditional space structure, the use division, the transportation system and the like are relatively slow in progress.

The city morphology of China always follows the trend from planning and design to construction and maintenance and from vehicles to system management, but the continuous learning and replication of the paths of Western civilization has basically reached the limit in many aspects, and the new situation requires us to develop new paths, namely paths without precedent in the world, both in the design concept level and in the scientific and technological engineering level.

The efficiency of a traffic system is improved, the free welfare of human beings is improved, and the constant pursuit of urban civilization innovation is achieved.

The invention is one of the series inventions of the next generation city civilization, and the innovation of design ideas and scientific engineering in the aspects of transportation means, transportation modes and management systems is emphatically tried.

Disclosure of Invention

In the existing traditional traffic system, intelligent vehicles with automatic driving functions gradually appear and are more and more, and the following defects are exposed.

Intelligent vehicles with automatic driving function have various brands and models, different sizes and specifications, different automatic driving grade designs, different integration degrees of automatic driving and auxiliary driving, different performance indexes of automatic driving function, different specific maneuvering actions selected and planned by automatic driving function, it is generally difficult for traffic participants to quickly identify, determine and know whether a vehicle with which they are or may interact is an autonomous vehicle, whether the vehicle is in an autonomous driving state, a specific action under the autonomous driving function, a specific amplitude of making the specific action, a specific process of making the specific action, a specific timing of making the specific action, a specific mileage of making the specific action, a specific path of making the specific action, a specific speed of making the specific action, driving control action information corresponding to a driving control command issued by a human driver or a human passenger on the vehicle to the smart vehicle, and the like. Because the traffic participants can not establish quick recognition and sensitive vigilance of the vehicle in the automatic driving state and can not form clear and accurate expectation on the specific action behavior of automatic driving, the traffic participants are difficult to make proper reaction and action in coordination with the automatic driving behavior, and traffic accidents are easy to happen. Because the action intention of the automatic driving vehicle in the traditional traffic monitoring video is not clear and definite, the related traffic management departments are relatively difficult to monitor, obtain evidence and enforce law, and the obtained information is not comprehensive and complete.

The inherent defects of the machine system are that "the people do not know what they do, and people cannot design all endless traffic conditions for the automatic driving machine system in advance, so that people may be concerned about the uneasiness, fear, frightened feeling and distrust of intelligent vehicles with the automatic driving function, which generally inhibits the acceptance, approval, welcome and use of the intelligent vehicles with the automatic driving function by consumers and society, and the future intelligent traffic with the essential characteristics of the great popularization of the intelligent vehicles is difficult to come later.

In order to solve the problems, the invention adopts the following technical scheme:

the intelligent vehicle with the automatic driving function carries out signal prompt on the traffic participants according to the information of the driving state and the action intention;

the prompt information in the automatic driving state enables the traffic participants to know that the vehicle is in the automatic driving state;

the action information combined with the immediate time countdown data enables the traffic participants to know the combination information of the time and the action related to the automatic driving of the vehicle, such as how long a certain action lasts, how long later a certain action is made, when a certain action is made, and the like, and the time data is immediately counted down along with the progress of the driving of the vehicle;

the traffic participants can know the combination information of the mileage and the action related to the automatic driving of the vehicle by combining the action information of the instant mileage countdown data, for example, how many miles a certain action lasts, what action is to be taken after the many miles, and the like, and the mileage data is immediately counted down along with the progress of the driving of the vehicle;

the action information combined with the path information enables the traffic participants to know the combination information of the path and the action related to the automatic driving of the vehicle, such as what maneuvering path a certain action will form and what action will be made by the certain path;

the action information combined with the speed information enables the traffic participants to know the combined information of the speed and the action related to the automatic driving of the vehicle, for example, a certain action is executed at a certain speed, and a certain action enables the vehicle to reach a certain speed;

driving control action information corresponding to a driving control command sent by a human driver or a human passenger on the intelligent vehicle enables a traffic participant to know the driving control action currently executed or to be executed by the vehicle and commanded by the human, such as current acceleration, current deceleration, current braking, current parking, current steering, to-be-accelerated, to-be-decelerated, to-be-braked, to-be-parked, to-be-steered, current forward, current backward, emergency braking, emergency parking and emergency parking by side under the driving control of the human driver or the human passenger;

action information in combination with use information lets traffic participants know the use and action in combination with vehicle autodrive related, e.g. being used for transporting dangerous goods, being used for transporting pupils;

the action information combined with the destination information enables the traffic participants to know the combination information of the destination and the action related to the automatic driving of the vehicle, such as going to a hospital urgently, going to a charging field urgently, going to emergency rescue and relief work urgently;

information of human drivers or human passengers on the vehicle enables traffic participants to know information of passenger members and driving control preferences related to automatic driving of the vehicle, such as monitoring driving of the vehicle by the elderly, presence of infants on the vehicle;

the information mainly carries out signal prompt on traffic participants outside the vehicle, and the direction of the external signal prompt can be all directions of the front, the back, the left and the right of the vehicle;

the information can also carry out signal prompt on the traffic participants inside and outside the vehicle, and the substantive content of the prompt information inside and outside the vehicle can be synchronous and consistent.

The "traffic participant" herein refers to various vehicles, people, and managers of the traffic system in the traffic system, and simply refers to the vehicle and people who have direct or indirect relations with the traffic system, such as the vehicle driver and the seat driver of a conventional non-intelligent vehicle, the vehicle driver and the seat driver of an intelligent vehicle, a pedestrian, a person riding a human-powered bicycle (bicycle), a person riding an electric bicycle, a person driving a tricycle, and the like, and the related traffic management departments that perform monitoring, law enforcement, and the like.

The present invention brings about the following advantageous effects.

Although intelligent vehicles with automatic driving functions have various brands and models, various sizes and specifications, various automatic driving grade designs, various integration degrees of automatic driving and auxiliary driving, various performance indexes of automatic driving functions and various specific maneuvering actions selected and planned by the automatic driving functions, through the signal prompt of the invention, traffic participants can generally, easily and quickly identify, judge and know whether the vehicle which is or can interact with the traffic participants is a vehicle with automatic driving functions, whether the vehicle is in an automatic driving state, specific actions under the planning of automatic driving functions, specific amplitude of specific actions, specific processes of specific actions, specific moments of specific actions, specific mileage of specific actions, specific paths of specific actions, specific speed of specific actions, And a human driver or a human passenger on the vehicle sends driving control action information corresponding to the driving control command to the intelligent vehicle. The traffic participants can establish quick identification and sensitive vigilance of the automatic driving state of the intelligent vehicle, and clear and accurate expectation can be formed on the specific automatic driving action, so that appropriate coordination reaction and action are easily made, the safety of the intelligent vehicle and a traffic system is improved, and traffic accidents are reduced or prevented. Related traffic management departments can also be easier in monitoring, evidence obtaining and law enforcement, clear and definite action intention information of the automatic driving vehicle is contained in a traditional traffic monitoring video, so that the responsibility of each party in an accident and the execution effect of the automatic driving action can be effectively judged, and a more comprehensive and complete investigation and demonstration result can be obtained by combining the calling and analysis of the driving data of the automatic driving vehicle.

Since the signal prompting mode is stronger and contains more information than the traditional signal prompting mode of the existing traditional vehicle, such as an LED dot matrix display screen which is brighter than the traditional turn signal brake lamp and contains more information, such as voice broadcast which is louder than the traditional vehicle horn and contains more information, the signal prompting mode of the invention can play the role of actively warning and driving away possible threats, such as warning and driving away pedestrians who violate traffic regulations and walk on the nerves in a motor vehicle lane, and thus actively warning and preventing possible dangers.

Meanwhile, the use information, the destination information, the information of the human driver or the human passenger and the like in the signal prompt expand and deepen the wider and deeper context understanding of the traffic participants to the traffic behaviors of the intelligent vehicle, so that more tacitly, subsumption, safety sense, goodwill and coordination are formed in psychology and behaviors.

The signal prompt is carried out on all the directions of the outside of the vehicle, namely the front direction, the rear direction, the left direction and the right direction, so that the information receiving range of the traffic participants is enlarged.

The prompt of synchronous consistency between the inside and outside of the vehicle is carried out on the substantive content of the information, so that the traffic participants inside and outside of the vehicle can form clear and accurate expectation on the specific actions of automatic driving, and therefore, the coordinated and appropriate reaction and action are easy to make.

Since prompt information of driving states and action intentions sent by the intelligent vehicle with the automatic driving function is received earlier and more easily, the feelings of uneasiness, fear, frightened feeling and distrust of human beings are eliminated or relieved, which generally improves the acceptance, recognition, welcome and use of the intelligent vehicle with the automatic driving function by consumers and society, and future intelligent traffic with the essential characteristic of great popularization of the intelligent vehicle can come as early as possible.

Detailed Description

The invention is suitable for intelligent vehicles with automatic driving function in any traffic system, in particular to a traffic system for mixed traffic of various traffic participants such as various traditional non-intelligent vehicles, various intelligent vehicles, pedestrians, people riding bicycles (bicycles), people riding electric bicycles, people driving tricycles and the like.

The signal prompt can be in a visual form or an audio form. The visual form, such as an LED dot matrix display screen, can integrate a steering lamp signal, a brake lamp signal and the like required by the traditional vehicle, the driving control action signal prompt of automatic driving is displayed in yellow, and the driving control action signal prompt corresponding to the driving control command sent by human is displayed in red; in the form of sound, for example a voice broadcast.

The signal can be kept all the time or sent out according to the need. The information can be prompted in a single bar or can be prompted in a rolling mode.

The specific embodiment of the signal prompt in visual form is exemplified as follows:

the prompt information in the automatic driving state makes the traffic participants know that the vehicle is in the automatic driving state, and the information in the automatic driving state can be either explicit or implicit. For example: the words of 'automatic driving' can be brightly and clearly indicated on the display screen to indicate that the vehicle is in the automatic driving state, and the display screen with limited display area is completely occupied for displaying the automatic driving action information and does not indicate the words of 'automatic driving' and can also effectively indicate that the vehicle is in the automatic driving state; for example: the display screen is not lightened to prompt that the vehicle is in a traditional manual driving state, and the display screen is lightened to prompt that the vehicle is in an automatic driving state; for example: a running horse lamp in a certain specified form on a display screen is displayed as a prompt that the vehicle is in an automatic driving state;

the action information in combination with the instantaneous time countdown data allows the traffic participants to know the combination of time and action related to the automatic driving of the vehicle, e.g., how long an action will last, how long after an action will be taken, when an action will be taken, etc., and the time data is immediately decremented as the driving of the vehicle progresses. For example: the display screen displays 'parking waiting for 15 seconds', 'changing lane to the left after 5 seconds', 'starting when 10: 00', wherein in the former two examples, the time figures are displayed in a mode of counting down instantly along with the lapse of time or the progress of driving;

the action information combined with the instant mileage countdown data enables the traffic participants to know the combination information of the mileage and the action related to the automatic driving of the vehicle, such as how many miles a certain action lasts, what action is to be taken after how many miles a certain action lasts, and the like, and the mileage data is immediately counted down along with the progress of the driving of the vehicle. For example: the display screen displays 'straight running for 1.5 kilometers', 'descending after 2.5 kilometers', 'parking to the right side after 200 meters', wherein mileage numbers are displayed in a reciprocal manner in real time along with the progress of driving;

the movement information combined with the path information allows the traffic participants to know the combination of the path and the movement related to the automatic driving of the vehicle, such as what maneuvering path a certain movement will form and what movement will be made with what path. For example: the display screen displays that 'a left turn enters a 2 nd lane from the left' and 'a parking area enters the 1 st lane from the left';

the action information in combination with the speed information lets the traffic participants know the speed and action information in connection with the automatic driving of the vehicle, e.g. an action to be performed at a certain speed, an action to be made to bring the vehicle to a certain speed. For example: the display screen displays 'direct running 110 km/h' and 'direct running accelerated to 80 km/h';

the driving control action information corresponding to the driving control command sent by the intelligent vehicle by the human driver or the human passenger on the intelligent vehicle enables the traffic participants to know the driving control action currently executed or about to be executed by the vehicle, such as current acceleration, current deceleration, current braking, current parking, current steering, about to be accelerated, about to be decelerated, about to be braked, about to be parked, about to be steered, current forward, current backward, emergency braking, emergency parking and emergency parking by side under the driving control of the human driver or the human passenger. For example: the display screen displays acceleration, deceleration, braking, parking, lane changing to the right, acceleration after 5 seconds, deceleration after 5 seconds, braking after 5 seconds, parking after 5 seconds, lane changing to the right after 5 seconds, advancing, backing, emergency braking, emergency parking and emergency parking beside parking. For example: the intelligent vehicle calculates and translates the driving control command into corresponding driving control action information of turning right after 425 meters according to the driving condition and displays the driving control action information on a display screen for signal prompt;

the action information in combination with the usage information lets the traffic participants know the usage-and action-related combination information of the automatic driving of the vehicle, for example being used for transporting dangerous goods, being used for transporting pupils. For example: the display screen displays 'transporting dangerous goods', 'transporting pupils';

the action information combined with the destination information enables the traffic participants to know the combination information of the destination and the action related to the automatic driving of the vehicle, such as going emergently to a hospital, going urgently to a charging field, going emergently to rescue and relief work. For example: the display screen displays 'just going to the first people hospital in emergency', 'just going to the third charging field', 'just going to the Wenchuan earthquake disaster area in emergency';

the information of human drivers or human passengers in the vehicle makes the traffic participants aware of information about passenger members and driving control preferences related to the automatic driving of the vehicle, e.g., the vehicle is driven by the elderly, the presence of a baby in the vehicle. For example: the display screen displays 'driving control by the long person' and 'baby in the display screen';

the information mainly carries out signal prompt on traffic participants outside the vehicle, and the direction of the external signal prompt can be all directions of the front, the back, the left and the right of the vehicle. The equipment that signal prompt sends the report can set up in positions such as roof, automobile body, car side, car outside, can realize all orientations with rotatory mode, also can all set up the equipment that information prompt sent the report to all 4 directions of controlling around to, for example:

the LED dot matrix display screens are arranged on the roof of the vehicle forwards, backwards, leftwards and rightwards;

the information can simultaneously prompt the traffic participants inside and outside the vehicle, and the substantive content of the prompt information inside and outside the vehicle can be synchronous and consistent. The display screen inside the car and the display screen outside the car can synchronously display the same contents completely, and can also synchronously display the same substantive contents in different styles respectively, for example: the display screen outside the vehicle displays 'direct driving 10 kilometers', and simultaneously the display screen inside the vehicle prompts the same information content in the form of a map road pattern combined with an arrow and a number;

the visual signal prompt may be performed in a text-to-number format, or may be performed in a graphic or symbol-to-number format, for example: "lane change to left after 5 seconds" may be displayed, and "← 5" may also be displayed.

The above-described signal presentation in a visual form can be easily converted into an appropriate sound form, such as a synthesized voice broadcast, and can be applied to signal presentation for the inside and outside of a vehicle, and can be mainly applied to the inside of a vehicle. For example: when the display screen for carrying out signal prompt outside the vehicle displays 'down ramp right after 2 km', the synthesized voice system for carrying out signal prompt inside the vehicle broadcasts 'down ramp right after 2 km'.
