The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.
The embodiment of the invention provides a vehicle ACC function intelligent control method, which is combined with a flow chart shown in FIG. 1 and comprises steps 101 to 105:
step 101: acquiring trigger parameters, the mileage of the vehicle, the speed of the vehicle and navigation high-speed information;
wherein the method is performed by a controller on the vehicle. The trigger parameters are stored in a rules engine file in the cloud. After the vehicle starts or is electrified, the mileage, the speed and the navigation high-speed information of the current running are acquired. The present running refers to running from the last ignition start of the vehicle, or may be running from the last vehicle speed of 0. Mileage refers to the continuous distance traveled this time. And vehicle speed refers to the current real-time vehicle speed. The navigation high-speed information is information for characterizing whether the vehicle is traveling on a high-speed road section. If the navigation high-speed information is a high-speed road section, the vehicle is indicated to run on the high-speed road at the present time. If the navigation high-speed information is a non-high-speed road section, the vehicle is not driven on the high-speed road at this time.
The triggering parameters are some parameter information for judging whether the vehicle meets the unlocking condition of the ACC function. The trigger parameters may include trigger vehicle speed, trigger mileage for comparison with actual mileage of the vehicle, vehicle speed.
Step 102: judging whether the unlocking condition of the ACC function is met or not according to mileage, speed, navigation high-speed information and triggering parameters;
in this embodiment, after acquiring the mileage, the vehicle speed, the navigation high-speed information and the trigger parameter, the vehicle running mileage is compared with the trigger mileage, and the vehicle running speed is compared with the trigger vehicle speed, and the navigation high-speed information is combined, so as to finally determine whether the running environment of the vehicle running this time meets the unlocking condition of the ACC function. In an alternative implementation mode, if the vehicle speed is greater than the trigger vehicle speed, the mileage is greater than the trigger mileage, and the navigation high-speed information is a high-speed road section, the vehicle meets the unlocking condition of the ACC function; otherwise, not satisfied.
It should be noted that this step is to determine the unlock condition of the ACC function, rather than determine whether to activate the ACC function. In this embodiment, the ACC function is locked and temporarily disabled at the beginning of the present running of the vehicle. The driver cannot activate the ACC function through a key on the steering wheel or a soft switch on the end screen. In this embodiment, before the ACC function is started, the vehicle controller may determine according to the currently acquired data, unlock the ACC function if it is determined that the current running environment meets the condition for use of the ACC function, and still lock the ACC function if it is determined that the current running environment does not meet the condition for use of the ACC function. Therefore, the running environment meeting the use condition can be intelligently screened out, and some running environments not meeting the use condition can be screened out, so that the problem of driving safety caused by starting the ACC function in the environment is avoided. Compared with the method that the ACC function is started through subjective judgment of a driver, the driving safety can be effectively improved through the scheme. After all, the judgment standard of each driver is different, and if the ACC function is started, the driving safety problem is likely to be caused for some environments unsuitable for using the ACC function.
Step 103: if the unlocking condition of the ACC function is met, sending starting prompt information to a driver;
in this embodiment, after the unlocking condition of the ACC function is satisfied, the ACC function is unlocked, and the controller determines that the running environment is suitable for turning on the ACC function. But eventually whether the ACC function is turned on is determined by the driver. Thus, a start prompt message may be sent to the driver, including a voice prompt or a push card prompt or a virtual action prompt. That is, after the ACC function is unlocked, the driver is prompted by voice, card or virtual action to determine whether to activate the ACC function.
At this time, the driver may or may not want to start. If the driver wants to start, the driver can send a control instruction in a voice response or card clicking mode. After receiving the control instruction sent by the driver, the ACC function of the vehicle can be controlled to be started according to the control instruction.
For example, the trigger vehicle speed is 80km/h and the trigger mileage is 30km. After the vehicle starts for a period of time, the mileage of the vehicle is 32km, the speed of the vehicle is 85km/h, the navigation high-speed information is a high-speed road section, and the vehicle is judged to meet the unlocking condition of the ACC function. After the ACC function is unlocked, a voice prompt is sent to the driver, for example, "whether to turn on the ACC function" and the driver says "turn on". After detecting the voice control instruction of the driver, the ACC function is started.
Step 104: acquiring historical use data of ACC;
in this embodiment, each time the ACC function is unlocked, it is recorded in the usage data, and if the ACC function is activated, it is also recorded in the usage data.
When the ACC function is unlocked, historical usage data is acquired. The historical usage data comprises unlocking times and starting times, and the historical usage data does not record the unlocking and starting.
Step 105: and adjusting the trigger parameters according to the historical use data.
It should be noted that, after the ACC function is started each time, the trigger parameter in this embodiment determines whether update is required, so that the determination of the ACC function unlocking condition better accords with the driving habit of the driver.
In an alternative embodiment, the specific step of adjusting the trigger parameter according to the historical usage data may comprise:
determining unlocking times and starting times of ACC functions according to the historical use data;
if the starting times are greater than a preset threshold, updating the triggering parameters according to the unlocking times, the starting times and the triggering parameters to obtain updated triggering parameters, and resetting the unlocking times and the starting times;
if the number of times of use is less than or equal to a preset threshold value, the trigger parameter is maintained.
The unlocking times and the starting times determined according to the historical use data are data accumulated before the running. It will be appreciated that the unlocking times and the starting times are not necessarily equal, and the unlocking times are greater than or equal to the starting times. Because the ACC function is not necessarily activated after each ACC function is unlocked.
But whether to update the trigger parameter is based on the number of starts. When the number of starts is greater than a preset threshold, the trigger parameter needs to be updated. And acquiring updated triggering parameters when the next time the vehicle is electrified or started. When the trigger parameters are updated, historical use data is also cleared, namely the unlocking times are cleared, and the starting times are cleared.
And when the starting times are smaller than or equal to a preset threshold value, the trigger parameters do not need to be updated.
In an alternative embodiment, updating the trigger parameter according to the unlocking times, the starting times and the trigger parameter to obtain an updated trigger parameter includes:
updating the trigger speed according to the trigger speed, the unlocking times and the starting times to obtain the updated trigger speed;
and updating the trigger mileage according to the trigger mileage, the function unlocking times and the use times to obtain the updated trigger mileage.
Specifically, the trigger vehicle speed may be updated by the following formula, to obtain an updated trigger vehicle speed:
wherein V is new For updated trigger speed V old To trigger the vehicle speed before updating, N Number of unlocking times For the number of unlocking times recorded in history, N Number of starts The number of times of starting is recorded as history.
The trigger mileage can be updated by the following formula to obtain the updated trigger mileage:
wherein S is new S is the updated trigger mileage old To trigger mileage before update, N Number of unlocking times For the number of unlocking times recorded in history, N Number of starts The number of times of starting is recorded as history.
In addition, in order to avoid the failure of the ACC function to start up, in consideration of the need to unlock the ACC function before starting up, in one embodiment, the method of the present embodiment further includes:
acquiring clicking operation times of the ACC function control in a preset time period;
and if the clicking operation times are larger than the clicking threshold value, checking the ACC function of the vehicle.
Wherein the preset time period is a preset short time, such as 2 seconds or 3 seconds. During this period, the driver can quickly click the ACC functionality controls on the steering wheel multiple times. If the controller detects that the number of times of clicking operation is greater than the clicking threshold value in the preset time period, for example, the number of times of clicking operation is greater than 3, the controller starts to verify the ACC function. If the ACC function fails, a failure prompt message is sent to a driver.
In summary, the embodiment of the present specification provides a vehicle ACC function intelligent control method, by acquiring a trigger parameter, a current driving mileage, a current driving speed, and a navigation high-speed information; judging whether the unlocking condition of the ACC function is met or not according to mileage, speed, navigation high-speed information and triggering parameters; if the unlocking condition of the ACC function is met, sending starting prompt information to a driver; acquiring historical use data of ACC; and adjusting the trigger parameters according to the historical use data. Therefore, through intelligent screening and judgment on the current running environment, after the running environment suitable for turning on the ACC function is determined, the use limit of the ACC function is unlocked, so that a driver can start the ACC function. The problem of safety caused by using ACC function in non-ideal environment is avoided, and the driving safety of the driver is improved.
