Detailed Description
In order that the above-recited objects, features and advantages of the present disclosure may be more clearly understood, a more particular description of the disclosure will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings. It is to be understood that the described embodiments are some, but not all, of the embodiments of the present disclosure, and that the specific embodiments described herein are merely illustrative of the present disclosure and not limiting of the present disclosure, and that the embodiments of the present disclosure and features of the embodiments may be combined with each other without conflict. All other embodiments derived by a person of ordinary skill in the art based on the described embodiments of the present disclosure fall within the scope of the present disclosure.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced otherwise than as described herein; it will be apparent that the embodiments in the specification are only some, but not all, embodiments of the disclosure.
Fig. 1 is a schematic flow chart of a vehicle control method according to an embodiment of the present disclosure, where the vehicle control method may be performed by a vehicle control device according to an embodiment of the present disclosure, and the vehicle control device may be implemented by software and/or hardware and may be integrated on a vehicle.
Illustratively, a schematic structural diagram of a vehicle according to an embodiment of the present disclosure is shown in fig. 2, in which a driver monitoring system (Driver Monitor System, DMS), a microphone, and a gas sensor are installed. The pickup can be used for mobile phone driver voice information; the gas sensor can detect the alcohol degree of the driver to judge whether the driver drinks or not; the DMS can activate the onboard camera to capture the driver's biometric features, such as facial images, eye features, etc. It will be appreciated that although not shown in fig. 2, the vehicle described in embodiments of the present disclosure may also incorporate other components or devices such as inertial measurement units (Inertial Measurement Unit, IMU), vision sensors, infrared sensors, global navigation satellite systems (Global Navigation Satellite System, GNSS), telematics BOX, T-BOX, and the like. The vehicle can interact information with the cloud server through the T-BOX.
As shown in fig. 1, the vehicle control method provided by the embodiment of the disclosure may include the following steps:
and step 101, acquiring identity information of a driver when the driver is detected to enter a driving position.
For example, a pressure sensor may be installed under the driver's seat, and when it is detected that the pressure value of the pressure sensor is greater than a preset pressure, it is determined that the driver enters the driver's seat.
For example, an infrared sensor may be installed in front of the driver's seat, and when it is detected that the distance from the infrared sensor to the obstacle becomes small, it is determined that the driver is driving.
For example, an image of the driver's seat may be acquired in real time or periodically by an onboard camera, and when it is recognized from the image that the driver's seat is occupied, it is determined that the driver enters the driver's seat.
In the embodiment of the disclosure, when the driver is determined to enter the driving position, the identity information of the driver is acquired.
As an optional implementation manner, when the driver is determined to enter the driving position, the user can be prompted to input the identity information of the user through voice, input of a central control panel and other modes, and the vehicle acquires the identity information of the driver according to the input of the driver.
As an alternative embodiment, the identity information of the driver may be obtained according to the biological characteristics of the driver. When the driver is detected to enter the driving position, the biological characteristics of the driver are collected, and then the identity information of the driver is determined according to the collected biological characteristics.
Biological features include, but are not limited to, facial features, iris features, voiceprint features, and the like.
For example, when it is determined that the driver enters the driving position, the DMS may be controlled to start the camera to collect a face image of the driver, and further analyze the obtained face image to obtain a face feature of the driver.
For example, when it is determined that the driver enters the driving position, the driver may be prompted to read a preset text, the sound pickup collects voice information of the driver, and the vehicle recognizes voiceprint features of the driver according to the voice information collected by the sound pickup.
In the embodiment of the disclosure, after the biological characteristics of the driver are obtained, the identity information of the driver can be determined according to the biological characteristics.
The identity information of the driver includes, but is not limited to, the name, age, sex and whether the driver has a driver license.
The method includes the steps that when a user drives a vehicle for the first time, under the condition that user authorization is obtained, the user is prompted to conduct identity registration, relevant information of the user is input, after the user registration is completed, registration information of the user is stored in a local or cloud server, when the user is registered, the vehicle collects biological characteristics of the user as identity identification, and the biological characteristics and the corresponding registration information are stored in the local or cloud server together. After the driver gets on the vehicle, the vehicle queries from a local or cloud server according to the acquired biological characteristics, and acquires registration information matched with the biological characteristics as identity information of the driver.
It can be understood that compared with the case that the registration information of the user is stored locally and stored in the cloud server, the registration information can be ensured to be queried according to the corresponding biological characteristics of the user when the same user drives different vehicles, the user does not need to perform identity registration each time when driving a new vehicle, and information sharing among vehicles is realized.
In an alternative implementation method of the present disclosure, after the identity information of the driver is determined, if the driver's identity information includes information of no driver license, the vehicle is controlled to prohibit starting, so that when the driver starts the vehicle, the vehicle does not respond to the operation of starting the vehicle by the driver, thereby avoiding the no-license driving problem.
Step 102, according to the identity information, acquiring a historical driving record of the driver.
In the embodiment of the disclosure, after the identity information of the driver is determined, the historical driving record of the driver may be continuously acquired.
For example, during each driving of the vehicle, the speed, acceleration, change information of each sensor or component on the vehicle, and the like of the vehicle may be monitored to obtain driving data of the vehicle, analyze the driving record of the driver, and upload the driving record of the driver to the cloud server for storage after the driving is completed. And after the identity information of the driver is determined when the driver drives the vehicle again, uploading the identity information to a cloud server through a T-BOX, and calling the historical driving record of the driver matched with the identity information.
For example, a driving record of the vehicle may be stored in a local memory of the vehicle for a preset time (e.g., last three months, last month, etc.). In each driving process of the vehicle, the speed, acceleration, change information of various sensors or components on the vehicle and the like of the vehicle can be monitored to obtain driving data of the vehicle, driving records of a driver are analyzed, and after driving is finished, the driving records of the driver are stored locally. For historical driving records exceeding the preset time, the historical driving records are automatically cleared from the local memory, so that the local memory space is saved. And then, when the driver drives the vehicle again, inquiring a local memory of the vehicle according to the determined identity information of the driver, and acquiring a historical driving record of the driver matched with the identity information.
And step 103, limiting the control authority of the vehicle in response to the historical driving record meeting a preset driving authority limiting condition.
The driving right limiting conditions can be preset according to actual requirements, for example, the driving right limiting conditions can be set to at least one of driving behaviors such as overspeed driving, red light running, illegal lane changing, rapid acceleration, rapid braking, rapid turning and the like, and dangerous driving behaviors in the driving record; for another example, the driving right limitation condition may be set such that the number of times of the driving record that there is an illegal driving behavior such as speeding, running a red light, changing a lane in a violation, accelerating a speed, braking a speed, turning a speed, etc. reaches a preset number of times threshold.
In the embodiment of the disclosure, after the history driving record of the driver is obtained, the history driving record may be analyzed, whether the history driving record meets the preset driving right limitation condition is judged, and when it is determined that the history driving record meets the driving right limitation condition, the control right of the vehicle is limited.
The control authority of the limited vehicle may be preset according to actual requirements, for example, the control authority of the limited vehicle may be set as a high-speed gear control authority of the vehicle, that is, the control authority of the driver on the high-speed gear of the vehicle is invalid, that is, the driver does not respond when controlling the high-speed gear of the vehicle to speed up; for another example, the control authority of the vehicle to be limited may be set to limit the power, that is, the stroke of the accelerator pedal is controlled slowly, and when the driver steps on the accelerator, the speed of the vehicle and the degree of the speed increase are both limited.
In an optional embodiment of the disclosure, a plurality of different driving right limitation conditions may be further set, and corresponding control rights are set for each driving right limitation condition, so when it is determined that the historical driving record meets the driving right limitation conditions, a matched control right is determined according to the driving right limitation conditions met by the historical driving record, and then the control right for driving the vehicle by the driver is limited according to the determined control right.
For example, it is assumed that the first driving authority limit condition is that a sharp turn exists in the driving record, the corresponding control authority limit is that the rotation angle of the steering wheel is from 90 degrees to 90 degrees, and the second driving authority limit condition is that overspeed driving exists in the driving record, and the corresponding control authority limit is that a high-speed gear of the vehicle is not available. When the obtained history driving record of the driver includes a sharp turning record, it is determined that the history driving record of the driver satisfies a driving right restriction condition one, and in response to the history driving record satisfying a preset driving right restriction condition, the control right of the restriction vehicle restricts the rotation angle of the steering wheel of the vehicle to be 90 ° left-turn to 90 ° right-turn. When the obtained history driving record of the driver includes a sharp turning record and an overspeed driving record, it is determined that the history driving record of the driver satisfies both the first driving right restriction condition and the second driving right restriction condition, then in response to the history driving record satisfying the preset driving right restriction condition, the control right of the restriction vehicle is a rotation angle of the steering wheel of the restriction vehicle of 90 ° left-turn to 90 ° right-turn, and the high gear of the restriction vehicle is invalid.
According to the vehicle control method, when the driver is detected to enter the driving position, identity information of the driver is obtained, then, according to the identity information, a historical driving record of the driver is obtained, and when the historical driving record meets preset driving right limiting conditions, the control right of the vehicle is limited. By adopting the technical scheme, the historical driving record of the driver is obtained, so that whether the driving right of the driver when driving the vehicle is determined according to the historical driving record of the driver is controlled, and when the historical driving record of the driver meets the driving right limiting condition, the control right of the vehicle is limited, so that the driving right of the vehicle is actively interfered according to the historical driving condition of the driver, the human factors possibly causing traffic accidents can be actively prevented, and the traffic accident rate is reduced.
In an alternative embodiment of the present disclosure, limiting the control authority of the vehicle in response to the historical driving record satisfying a preset driving authority limit condition includes:
analyzing whether dangerous driving records exist in the historical driving records;
when the dangerous driving record exists in the historical driving record, determining that the historical driving record meets a preset driving permission system condition;
the sensitivity of an accelerator pedal of the vehicle is adjusted to reduce the output power of the engine.
The dangerous driving records can include, but are not limited to, speeding, red light running, illegal lane changing, sudden acceleration, sudden braking, sudden turning and the like.
In the embodiment of the disclosure, after the history driving record of the driver is obtained, the obtained history driving record may be analyzed to determine whether a dangerous driving record exists in the history driving record, for example, when overspeed driving exists in the history driving record, the dangerous driving record exists in the history driving record. When the dangerous driving record exists in the historical driving record, the historical driving record is determined to meet the preset driving permission system condition, and the sensitivity of an accelerator pedal of the vehicle is further adjusted to reduce the output power of the engine.
It will be appreciated that the main function of the accelerator pedal is to control the opening of the throttle valve and thus the power output of the engine. The electronic accelerator is characterized in that a displacement sensor is arranged on an accelerator pedal of the electronic accelerator, when a driver steps on the accelerator pedal, an electronic control unit collects opening change and acceleration of the displacement sensor on the pedal, then the intention of the driver for power output is judged according to a built-in algorithm, and then a corresponding control signal is sent to a control motor of an engine throttle valve, so that the power output of the engine is controlled. In the embodiment of the disclosure, when the history driving record meets the driving right limiting condition, the built-in algorithm can be changed to reduce the sensitivity of the driving pedal, so that when the history driving record meets the driving right limiting condition, the power output of the engine is lower than that under the normal driving condition for the same opening change and acceleration of the displacement sensor, and the output power of the engine is reduced, thereby achieving the purpose of reducing the speed-up range of the vehicle speed.
In the embodiment of the disclosure, when the dangerous driving record exists in the historical driving record, the historical driving record is determined to meet the driving permission control condition, and the sensitivity of the accelerator pedal of the vehicle is further adjusted to reduce the output power of the engine, so that for a driver who has the dangerous driving record, the output power of the engine is reduced by adjusting the sensitivity of the accelerator pedal, the power output of the vehicle is limited, the speed raising capability of the vehicle is reduced, the speed of the vehicle during driving is limited, and the bad driving habit of the driver is corrected.
In an alternative embodiment of the present disclosure, a gas sensor may be further installed in the cockpit of the vehicle, and when it is detected that the driver enters the driving position, the gas sensor in the vehicle is activated to detect the alcohol level of the driver, and in case it is determined that the alcohol level is greater than a preset value, the vehicle is controlled to prohibit the activation.
The preset value may be preset, for example, may be set to 0, 0.02%, etc.
For example, when it is detected that the driver gets on the vehicle, a gas sensor on the vehicle is started, a prompt message such as "please blow to detect alcohol" is sent to the driver, the driver blows after receiving the prompt, the gas sensor detects alcohol content, and the vehicle judges whether the driver drinks according to the alcohol content detected by the gas sensor. If the detected alcohol degree is larger than the preset value, determining that the driver drinks the alcohol, and controlling the vehicle to prohibit starting. Therefore, drunk driving behavior of a driver can be avoided, and the occurrence rate of traffic accidents is reduced.
Generally, when the driver's state is poor, the probability of occurrence of a traffic accident is also relatively high, so, in order to avoid a traffic accident caused by the driver's state, in an alternative embodiment of the present disclosure, when the driver is detected to enter the driving position, a pickup installed in the vehicle may be started, voice information of the driver is obtained through the pickup, and a face image of the driver is obtained through the vehicle-mounted camera, and further, the current state of the driver is determined according to the obtained voice information and the face image, and further, the vehicle is controlled according to the current state of the driver and the state of the vehicle, wherein the state of the vehicle includes a stationary state or a driving state, and the stationary state of the vehicle includes two cases in which the vehicle is not started and in which the vehicle is started but not driven. Specifically, when the current state of the driver is determined to be a preset abnormal state and the vehicle is not started, limiting the control authority of the vehicle; and prompting the driver to drive carefully when the current state of the driver is determined to be an abnormal state and the vehicle is in a driving state.
Wherein the abnormal state is preset, and the abnormal state includes but is not limited to an excited state, a tired state, an anger state, an excited state and the like.
The intonation and the speaking content of a person speaking, and the facial expression of the person tend to reflect the current state of the person, for example, when the intonation of the person speaking is high, the person may be more active or angry, and if the person also speaks some of the more angry, the person may be more angry, and in combination with the facial expression of the person, the current state of the person can generally be determined more accurately. Therefore, in the embodiment of the disclosure, the voice information and the face image of the driver are acquired to determine the current state of the driver, the current state is matched with the preset abnormal state, whether the driver is in the abnormal state at present is judged, and if so, whether the vehicle is in the stationary state or the driving state at present is further determined. If the vehicle is currently stationary, control authority of the vehicle is restricted, such as lowering output power of an engine of the vehicle, restricting a part of authority of the vehicle, and the like. Therefore, when the driver is determined to be in an abnormal state and the vehicle is in a static state, the driving permission of the driver can be actively limited, and the occurrence rate of traffic accidents can be reduced.
In the embodiment of the disclosure, in the driving process of a vehicle, a pickup in the vehicle and a vehicle-mounted camera can be always in a working state, the pickup collects voice information of a driver in the driving process of the vehicle, the vehicle-mounted camera collects face images of the driver in the driving process of the vehicle, the vehicle determines the current state of the driver according to the voice information and the face images and matches the current state with a preset abnormal state, and when the current state is determined to be the abnormal state, the driver can be prompted to drive carefully, for example, the driver can be prompted to drive carefully by means of voice broadcasting, flashing of an indicator lamp, display of prompt text on a vehicle-mounted display screen and the like.
In the embodiment of the disclosure, the current state of the driver is obtained in real time in the running process of the vehicle, and the driver is prompted to drive carefully when the current state is determined to be the abnormal state, so that the driver with abnormal state can be actively reminded, dangerous driving of the driver is prevented as much as possible, and the traffic accident rate is reduced.
In practical application, when the emotion of the driver is large and the driver cannot calm for a long time, the driver may feel the discomfort of the driver all the time, and the actual effect cannot be generated. For this case, the vehicle may be actively controlled. Thus, in an alternative embodiment of the present disclosure, the number of times the driver is reminded of cautious driving may be counted during the driving of the vehicle within a preset period of time after the first prompting, and the vehicle may be controlled to slow down when the number of times is greater than a preset number of times threshold.
The preset duration and the preset frequency threshold can be preset. For example, the preset time period may be set to 1 minute, 3 minutes, or the like, and the preset number of times threshold may be set to 3 times, 5 times, or the like.
In the embodiment of the disclosure, in the driving process of the vehicle, after the driver is prompted to drive carefully for the first time, timing can be started, and in the time period when the timing time length reaches the preset time length, the number of times of prompting the driver to drive carefully in the time period is counted, the counted number of times is compared with a preset number of times threshold, and if the counted number of times is larger than the preset number of times threshold, the vehicle is controlled to decelerate.
For example, assuming that the preset duration is 1 minute and the preset number of times is 3, the number of times the driver is reminded of driving carefully in one minute after the driver is reminded of driving carefully for the first time in the driving process of the vehicle is counted, and if the counted number of times is more than 3, the vehicle is controlled to be decelerated.
It can be appreciated that the present disclosure is merely exemplified by controlling the vehicle to decelerate when the counted number of times is greater than the preset number of times threshold, and is not intended as a limitation of the present disclosure. According to actual demands, the vehicle can be controlled to enter an auxiliary driving mode, an automatic driving mode and the like when the counted times are larger than a preset time threshold value. In addition, when the road section where the vehicle is located divides a fast lane and a slow lane, the vehicle can be controlled to enter the slow lane while the vehicle is controlled to decelerate.
In the embodiment of the disclosure, the number of times of cautious driving of the driver is prompted in the preset time period after the first prompting of the driver is counted in the driving process of the vehicle, and the vehicle is controlled to be decelerated when the number of times is larger than the preset time threshold, so that the vehicle can be actively decelerated and controlled when the driver is not prompted for many times, the probability of accidents caused by the fact that the vehicle speed is too fast when the driver is in an abnormal state is reduced, and safe driving is guaranteed as much as possible.
In an alternative embodiment of the present disclosure, after determining the identity information of the driver, the method further comprises:
reporting the identity information to a cloud server;
receiving a target score returned by the cloud server, wherein the target score is determined by the cloud server according to the identity information;
and prompting the driver to carefully drive under the condition that the target score is smaller than a preset score.
The preset score may be preset according to actual requirements, for example, the preset score is set to 60 score, 80 score, etc.
In the embodiment of the disclosure, the cloud server can store the driving score of the driver after the driver finishes driving the vehicle every time, and when driving next time, the cloud server feeds back the driving score to the vehicle for reminding the driver to carefully drive so as to correct the driving habit of the driver. When the driver drives the vehicle for the second time, after the identity information of the driver is determined by the vehicle, the identity information can be reported to the cloud server, and after the cloud server receives the identity information reported by the vehicle, the target score of the driver matched with the identity information is determined and returned to the vehicle.
The cloud server may obtain all the historical scores of the target driver corresponding to the identity information after receiving the identity information reported by the vehicle, and then determine the target score according to all the historical scores. Wherein, in determining the target score, the target score may be determined by means of averaging, median, etc., which is not limited by the present disclosure.
For example, the driving score for a longer period of time is generally not great for the reference value of the driving habit of the driver, in this example, after the cloud server receives the identity information reported by the vehicle, the cloud server may acquire the driving score of the corresponding driver in the last period of time (such as the last week, the last half month, etc.), and then determine the target score according to the acquired driving score, so as to obtain the latest driving score of the driver to analyze the driving habit of the driver, and compare the latest driving situation of the driver.
Then, after the vehicle receives the target score returned by the cloud server, the target score can be compared with a preset score, and when the target score is determined to be smaller than the preset score, the driving habit of the driver is indicated to be bad, and the driver is prompted to drive carefully. Therefore, the driving behavior of the driver can be prompted according to the past driving scores of the driver, and the driving habit of the driver can be corrected.
In an optional embodiment of the disclosure, the running information of the vehicle may be obtained during the running process of the vehicle, and the current driving record of the driver may be determined according to the running information, so as to report the current driving record to the cloud server.
The running information of the vehicle comprises, but is not limited to, the speed of the vehicle in the running process of the vehicle, the running path of the vehicle, the braking force of a brake pedal of the vehicle, the acceleration force of an accelerator pedal, the acceleration size, road condition information and the like.
Illustratively, the speed of the vehicle may be obtained by a speed sensor, the path traveled by the vehicle may be obtained by a GNSS, the acceleration and braking forces may be obtained by displacement sensors on an accelerator pedal and a brake pedal, road condition information may be collected by cameras external to the vehicle, and so on. The electronic control unit collects and analyzes the running information of the vehicle and determines the current driving record of the driver, such as whether overspeed driving, illegal lane change and the like exist in the current driving. After the current driving record of the driver is determined, the vehicle reports the current driving record to a cloud server, and the cloud server binds the current driving record with the identity information of the driver so as to return to the historical driving record of the driver according to the identity information of the driver reported by the vehicle when the driver drives the vehicle next time.
In the embodiment of the disclosure, the running information of the vehicle is acquired in the running process of the vehicle, the current driving record of the driver is determined according to the running information, and then the current driving record is reported to the cloud server, so that data support is provided for limiting control authority according to the historical driving record of the driver when the driver drives the vehicle again.
In an optional embodiment of the disclosure, after the vehicle stops running, the driver may be scored according to the current driving record of the driver, and the current score of the driver may be reported to the cloud server.
The method includes the steps that corresponding scores and weights can be preset for different driving behaviors, after the current driving record of a driver is determined, driving behaviors contained in the current driving record are analyzed, then weighted summation is carried out on the scores and weights corresponding to each driving behavior, the current score of the driver is obtained and reported to a cloud server, and the cloud server binds the current score with identity information of the driver.
In the embodiment of the disclosure, after the vehicle stops running, the driver is scored according to the current driving record of the driver, and the determined score is reported to the cloud server, so that data support is provided for prompting the driver to carefully drive according to the history score of the driver when the driver drives the vehicle again, and the driving habit of the driver is corrected.
It can be understood that, in the embodiment of the disclosure, the operation of calculating the current score of the driver may also be completed by the cloud server, and the cloud server receives the current driving record reported by the vehicle, and further calculates the current score of the driver according to the current driving record, and binds the current driving record with the identity information of the driver, so as to update the driving record and the score.
