According to the above module structure, various embodiments of the method of the present invention are provided.
Referring to fig. 2, fig. 2 is a flowchart illustrating a vehicle speed guidance method according to a first embodiment of the present invention, including:
step S100, detecting whether an anti-collision function is triggered;
it is known that, for vehicles with an intelligent driving assistance system, an anti-collision function is mounted, which can automatically identify vehicles, pedestrians, or other obstacles that may collide with the vehicle, and issue an alarm or take measures such as braking or evasion at the same time to avoid the collision. When the vehicle predicts that a collision will occur, the anti-collision function is triggered to improve the safety of vehicle running. The anti-collision function can protect the vehicle from colliding with the front obstacles and can also protect the vehicle from colliding with the obstacles on two sides.
Step S200, if an anti-collision function is triggered, generating a judgment short message according to the driving information when the anti-collision function is triggered, and sending the judgment short message to a preset terminal so that a user can judge the trigger sensitivity for triggering the anti-collision function;
when the anti-collision function is triggered, the current driving information of the vehicle is recorded, where the driving information may include: the speed of the vehicle, acceleration, yaw acceleration, master cylinder pressure, and longitudinal distance of the vehicle from the obstacle, etc. By recording the driving information of the vehicle when the anti-collision function is triggered and generating the pre-judgment short message according to the driving information, the user can intuitively judge the trigger sensitivity for triggering the anti-collision function according to the judgment short message and the driving experience when the anti-collision function is triggered.
And step S300, receiving a degree word fed back by a preset terminal according to the judgment short message, and calibrating a parameter value triggering the anti-collision function according to the degree word.
And the user judges the trigger sensitivity of the anti-collision function by feeding back the degree word. In one embodiment, the term of degree is a judgment of the timing of the triggering of the collision avoidance function, such as the driver replying to one of "too slow", "fit", "fast", and "too fast". In another embodiment, the degree word is a judgment of the triggering distance of the collision avoidance function, such as the driver replying one of "too close", "slightly close", "fit", "slightly far", "far", and "too fast". Currently, the degree word may further include other descriptions with the same or similar meanings, so as to better enable the user to judge the trigger sensitivity of the anti-collision function.
It should be noted that the judgment short message should include information for guiding the user to return the degree word corresponding to the judgment of the trigger sensitivity, and of course, also include driving information when the anti-collision function is triggered.
An example is presented to aid understanding:
if the current driving information when the anti-collision function is triggered is as follows: vehicle speed 45km/s, brake master cylinder pressure: 3Bar, longitudinal distance of vehicle from obstacle: 30 m.
The generated judging short message is as follows:
"lovely users, based on the safety factor, we trigger the anti-collision function for you, and then your driving information is as follows:
vehicle speed: 45km/s
Brake master cylinder pressure: 3Bar
Longitudinal distance of vehicle from obstacle: 30m
Please evaluate the daemon experience: reverting to ' early, moderate ' and later '
The next time please pay more attention to road driving safety! The moment is your guard! "
It is understood that the embodiment does not limit the evaluation short message, and the evaluation short message may further include more forms of conversion, adding or subtracting related information, so that the user may know that the pause in the driving process is to start the anti-collision function at a certain time or at a certain position. The judging short message can also add time information when the anti-collision function is triggered, if the time when the anti-collision function is triggered is 14 days at 1 month and 28 months in 2021: 35, the first line in the above embodiment of the comment message may be changed to "lovely user," based on the safety factor, we are you in 2021, month, 28, day 14: 35, the anti-collision function is triggered, and then your driving information is as follows: if the position when the anti-collision function is triggered is the position 18 # of the southwestern willow area of the Guangxi province, the first line in the above embodiment of the judgment short message can be changed into a "lovely user", based on the safety factor, we trigger the anti-collision function for your 18 # of the southwestern willow area of the Guangxi province, and then the driving information of your is as follows: ".
It should be noted that, in one embodiment, the longitudinal distance between the vehicle and the obstacle corresponding to the triggering of the anti-collision function may be calibrated according to the degree word, in another embodiment, the braking deceleration corresponding to the triggering of the anti-collision function may be calibrated according to the degree word, and in another embodiment, the master cylinder pressure corresponding to the triggering of the anti-collision function may be calibrated according to the degree word.
The embodiment detects whether the anti-collision function is triggered; and if the anti-collision function is triggered, generating a judging short message according to the driving information when the anti-collision function is triggered, and sending the judging short message to a preset terminal so that a user judges the triggering sensitivity of triggering the anti-collision function. The parameter value corresponding to the anti-collision function is calibrated based on the degree word fed back by the driver by the step of receiving the degree word fed back by the preset terminal according to the judgment short message and calibrating the parameter value triggering the anti-collision function according to the degree word.
Further, referring to fig. 3, fig. 3 is a detailed flowchart of step S200 in a second embodiment of the present invention, based on the first embodiment, the collision avoidance function includes multiple collision avoidance items, where a corresponding collision avoidance item is determined to be triggered according to a longitudinal distance between an obstacle and a vehicle; the travel information includes: current vehicle speed, position, master cylinder pressure, and the longitudinal distance; the step S200 includes:
step S210, if the anti-collision function is triggered, recording the current speed, position, master cylinder pressure and longitudinal distance;
it will be appreciated by those skilled in the art that the current speed, position, and master cylinder pressure of the vehicle may be detected by onboard sensors, and the longitudinal distance of the obstacle from the vehicle may be detected by high-definition cameras or detection radars.
Step S220, generating a judgment short message corresponding to the triggered anti-collision item according to the vehicle speed, the position, the master cylinder pressure and the longitudinal distance;
the anti-collision function comprises a plurality of anti-collision items, such as an early warning prompt function, an inching brake function, an emergency brake function and the like. The early warning prompt function is to remind a driver to brake through sound and/or picture display according to the road condition of the vehicle, and the driver does not actively intervene in a brake system. The point brake function is that according to the road condition of the vehicle, the active intervention brake system brakes in a 'point brake' mode. The emergency braking function is that the active intervention braking system brakes by immediately increasing the braking force to the maximum according to the road condition of the vehicle. Obviously, compare emergency braking function, the inching braking function makes the gentle braking of vehicle, and the driving experience is better, nevertheless because under some circumstances, the braking force of inching braking function can not satisfy emergency braking requirement, needs trigger emergency braking function and avoids vehicle and barrier collision.
In this embodiment, the anti-collision items are triggered according to the determination of the longitudinal distance between the obstacle and the vehicle, for example, a first longitudinal distance between the obstacle and the vehicle triggers an early warning function, a second longitudinal distance between the obstacle and the vehicle triggers a point brake function, and a third longitudinal distance between the obstacle and the vehicle triggers an emergency brake function, where the longitudinal distance corresponding to each anti-collision item may be set by a person skilled in the art according to actual situations. Preferably, the first longitudinal distance is greater than the second longitudinal distance, which is greater than the third longitudinal distance. It can be understood that, in some cases, the vehicle speed is too high or due to the complex and variable traffic environment, the obstacle appears suddenly and is intercepted in front of the vehicle, and the like, so that the vehicle has no time to trigger the early warning prompting function, directly trigger the point brake function or the emergency brake function, or the vehicle has no time to trigger the early warning prompting function and the point brake function, and directly trigger the emergency brake function. In other cases, the vehicle triggers the early warning prompt function to remind the driver to brake, and the point brake function and the emergency brake function cannot be triggered due to timely braking of the driver. Similarly, since the vehicle controls the speed of the vehicle in time after the trigger point braking function, the emergency braking function is not triggered. Therefore, if there is a risk of collision with an obstacle in front of the vehicle during driving of the vehicle and an anti-collision item is triggered, the anti-collision item may be one of the early warning prompt function, the inching brake function, and the emergency brake function, may be a combination of any two of the early warning prompt function, the inching brake function, and the emergency brake function, and may be all of the early warning prompt function, the inching brake function, and the emergency brake function.
When the anti-collision item is an early warning prompt function, if the driving information of the current early warning prompt function is as follows: vehicle speed 45km/s, brake master cylinder pressure: 3Bar, longitudinal distance of vehicle from obstacle: 30 m.
In one embodiment, the generated evaluation short message is:
"lovely users, based on the safety factor, have triggered the warning prompt function for you, your information of going at that time is as follows:
vehicle speed: 45km/s
Brake master cylinder pressure: 3Bar
Longitudinal distance of vehicle from obstacle: 30m
Please evaluate the daemon experience: reverting to ' early, moderate ' and later '
The next time please pay more attention to road driving safety! The moment is your guard! "
It is understood that the embodiment does not limit the evaluation message, and the evaluation message may further include more forms of transformation, adding or subtracting related information. Similarly, when the anti-collision function is an inching brake function or an emergency brake function, the early warning prompt function in the first row of the embodiment may be replaced by the inching brake function or the emergency brake function. It will be appreciated that the associated travel information of vehicle speed, master cylinder pressure, and longitudinal distance of the vehicle from the obstacle recorded when each collision avoidance item is triggered will often be different.
Step S230, sending the judgment short message to a preset terminal, so that the user can judge the trigger sensitivity for triggering the anti-collision item.
In the embodiment, if the anti-collision function is triggered, the current vehicle speed, the current position, the current master cylinder pressure and the longitudinal distance are recorded, so that the current running information of the vehicle is recorded. And generating a judging short message corresponding to the triggered anti-collision item according to the vehicle speed, the position, the master cylinder pressure and the longitudinal distance so as to generate the judging short message corresponding to the triggered anti-collision item according to the current vehicle running information. Through the step of sending the judging short message to the preset terminal, the user can visually know the driving information of the vehicle when the anti-collision item is triggered, and the triggering sensitivity of triggering the anti-collision item is judged according to the driving experience when the anti-collision item is currently triggered.
Further, referring to fig. 4, fig. 4 is a detailed flowchart of step S300 in a third embodiment of the present invention, and based on the second embodiment, the step S300 includes:
step S310, receiving a degree word fed back by the preset terminal according to the judgment short message;
step S320, determining a preset algorithm corresponding to the triggered anti-collision item according to the triggered anti-collision item;
it is understood that each collision avoidance item has its corresponding preset algorithm. The trigger sensitivity of each anti-collision item can be calibrated more accurately by setting the corresponding preset algorithm of each anti-collision item.
Further, the anti-collision item comprises an early warning prompt function; the step of determining the preset algorithm corresponding to the triggered anti-collision item according to the triggered anti-collision item comprises the following steps:
determining a first preset algorithm corresponding to the early warning prompt function according to the early warning prompt function;
the first preset algorithm is as follows:
Figure BDA0003124460920000101
wherein h isdaTrigger distance, V for early warning prompt function1Is the speed of the vehicle, trSpeed of reaction, t, for the driversIs the system delay time, vrelIs the relative speed of the vehicle and the obstacle, amaxFor vehicle deceleration, d0Is the safe distance, mu, of the vehicle from the obstacle1Is a first sensitivity factor.
Wherein, the reaction speed of the driver, the delay time of the system, and the safe distance between the vehicle and the obstacle are preset by the technicians in the field. The relative speed of the vehicle and the obstacle, the deceleration of the vehicle and the speed of the vehicle need to be detected in real time through a vehicle-mounted sensor and/or a camera of the vehicle.
Further, the anti-collision items comprise a point brake function; the step of determining the preset algorithm corresponding to the triggered anti-collision item according to the triggered anti-collision item comprises the following steps:
determining a second preset algorithm corresponding to the point brake function according to the point brake function;
the second preset algorithm is as follows:
Figure BDA0003124460920000102
wherein h isdTrigger distance, V, for snub braking function1Is the speed of the vehicle, tsIs the system delay time, vrelIs the relative speed of the vehicle and the obstacle ahead, amaxFor vehicle deceleration, d0Is the safe distance, mu, of the vehicle from the obstacle2Is the second sensitivity factor.
Further, the collision avoidance item comprises an emergency braking function; the step of determining the preset algorithm corresponding to the triggered anti-collision item according to the triggered anti-collision item comprises the following steps:
determining a third preset algorithm corresponding to the emergency braking function according to the emergency braking function;
the third preset algorithm is as follows:
Figure BDA0003124460920000103
wherein h is the triggering distance of the emergency braking function, V1Is the speed of the vehicle, tsIs the system delay time, vrelIs the relative speed of the vehicle and the obstacle ahead, amaxFor vehicle deceleration, d0Is the safe distance, mu, of the vehicle from the obstacle3Is the third sensitivity factor.
It should be noted that the preset initial value of the first sensitivity factor and the preset initial value of the second sensitivity factor may be the same or different, but the preset initial value of the third sensitivity factor is smaller than the preset initial values of the first sensitivity factor and the second sensitivity factor, and the preset initial value may be set by a person skilled in the art according to actual situations. For example, the preset initial value of the third sensitivity factor is 0.8, the preset initial value of the second sensitivity factor is 1.2, and the preset initial value of the first sensitivity factor is 1.3.
Step S330, calibrating a sensitivity factor in the preset algorithm according to the degree word so as to update the preset algorithm;
in one example, the sensitivity factor is unchanged when reverting to the same or similar meaning of "moderate" or "appropriate". When the words with the same or similar meanings such as 'early' or 'faster' are returned, the sensitivity factor is reduced by a preset value. When the degree word of the reply is 'later' or 'later' and is related to the same or similar meaning, the sensitivity factor is increased by a preset value. The preset value can be set by a person skilled in the art according to actual conditions, for example, the preset value is 0.02.
Further, judging whether a first sensitivity factor in a first preset algorithm is smaller than a first preset threshold value or not;
it can be understood that, in the process of using the vehicle by the user, due to reasons such as the driving style of the driver being more "aggressive", the driver replies the same or similar degree words such as "as early" or "faster", the first sensitivity factor in the first preset algorithm is decreased by the preset value for a plurality of times, so that the first sensitivity factor is continuously decreased, at this time, the first sensitivity factor needs to be set to a first preset threshold, and when the first sensitivity factor is smaller than the first preset threshold, the safety early warning short message is sent to the preset terminal, so as to prevent the driving style of the driver from being too "aggressive", which causes the lower safety of the vehicle driving, thereby realizing the purpose of improving the driving experience of the driver using the anti-collision function as much as possible on the premise of ensuring the safety of the vehicle driving.
If the first sensitivity factor is smaller than a first preset threshold value, sending a safety early warning short message to a preset terminal;
when the first sensitivity factor is smaller than a first preset threshold, it is indicated that if the current sensitivity factor subtracts a preset value from the sensitivity factor according to a degree word (a degree word with similar meaning such as "early" or "faster" and the like) fed back by the driver, the driving safety of the vehicle is possibly affected, at this time, the driver is reminded by sending a safety early warning message to a preset terminal, so that the driver can realize that if the driver continues to reply the degree word with similar meaning such as "early" or "faster" and the like according to the personal driving experience, a potential safety hazard exists, it can be understood that the safety early warning message is different from the judgment message, and the judgment message is used for enabling the user to judge the triggering sensitivity of the anti-collision function and calibrate the parameter value of the anti-collision function. The safety early warning short message is used for reminding a user that the current sensitivity factor reaches the minimum critical value, and if the sensitivity factor is reduced, the driving safety is influenced. .
If the first sensitivity factor is greater than or equal to a first preset threshold, executing: and calibrating a first sensitivity factor in the first preset algorithm according to the degree word so as to update the first preset algorithm.
Further, whether a second sensitivity factor in a second preset algorithm is smaller than a second preset threshold value is judged;
in a similar way, the second sensitivity factor is set to be a second preset threshold value, the second sensitivity factor is prevented from being smaller than the second preset threshold value as much as possible, the driving safety of the vehicle is prevented from being lower due to reasons such as too aggressive driving style of the driver, and therefore the driving experience of the driver with the anti-collision function is improved to the maximum extent on the premise that the driving safety of the vehicle is ensured.
If the second sensitivity factor is smaller than a second preset threshold value, sending a safety early warning short message to a preset terminal;
similarly, the driver is reminded by sending the safety early warning short message to the preset terminal, so that the driver can realize that the potential safety hazard exists if the driver continuously replies the similar meaning words such as 'early' or 'faster' according to the personal driving experience
If the second sensitivity factor is greater than or equal to a second preset threshold, executing: and calibrating a second sensitivity factor in the second preset algorithm according to the degree word so as to update the second preset algorithm.
Step S340, calibrating and triggering a parameter value corresponding to the anti-collision item according to the updated preset algorithm.
In the embodiment, the preset algorithm for calibrating the trigger sensitivity of the anti-collision item is updated by the steps of receiving the degree word fed back by the preset terminal according to the judgment short message, determining the preset algorithm corresponding to the triggered anti-collision item according to the triggered anti-collision item, and calibrating the sensitivity factor in the preset algorithm according to the degree word. And calibrating the parameter values corresponding to the triggering of the anti-collision items according to the updated preset algorithm, so as to improve the accuracy of calibrating the triggering sensitivity of each anti-collision item.
Further, referring to fig. 5, fig. 5 is a detailed flowchart of step S300 in a third embodiment of the present invention, based on the first embodiment, the step S300 includes:
step S350, receiving a degree word fed back by a preset terminal according to the judgment short message;
step S360, judging whether the number of the degree words received by the history is accumulated to reach a preset number or not;
step S370, if the accumulation of the degree words fed back by the judgment short message reaches the preset number, counting the number of various degree words in the received degree words;
and step S380, calibrating parameter values corresponding to the triggered anti-collision function according to the most degree words, and clearing the number of the degree words received historically.
It can be understood that, in this embodiment, the trigger sensitivity of the anti-collision function is calibrated according to the degree word each time the driver feeds back the degree word, but the trigger sensitivity of the anti-collision function is calibrated according to the degree words of the preset number after the degree words received historically reach the preset number. And when the parameter value corresponding to the anti-collision function is calibrated once, the number of the degree words received by the peer-to-peer history returns to zero, and the statistics is repeated and repeated in a circulating way.
The embodiment counts and analyzes the anti-collision function trigger sensitivity which best meets the real intention of a user through accumulating a certain number of samples of the degree words fed back by the user, reduces subjective contingency caused by the anti-collision function trigger sensitivity calibrated by a single degree word sample, and reduces calibration deviation caused by the subjective contingency of parameter values corresponding to the anti-collision function calibrated by the user, thereby improving the accuracy of calibrating the anti-collision function trigger sensitivity, and further improving the use experience of the user on the anti-collision function.
