Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
The following describes a cruise control method, apparatus, and vehicle according to an embodiment of the present invention with reference to the accompanying drawings.
As shown in fig. 1, the related display interface in the cruise control mode according to the embodiment of the present invention includes four parts, namely, a cruise control function indicator; displaying the actual vehicle speed; thirdly, displaying the target speed; and fourthly, displaying only the vehicle speed specific value actually shown in the figure 1 in the main display when the constant-speed cruise is not started, and displaying the information related to the constant-speed cruise shown in the figure 2(a) after the constant-speed cruise function is started.
Fig. 3 is a flowchart of a constant-speed-cruise safety control method according to a first embodiment of the present invention, as shown in fig. 3, the method including:
and S101, starting a constant-speed cruise function, and displaying a preset target vehicle speed.
It can be understood that a fixed target vehicle speed is correspondingly set for the constant-speed cruise function in advance, and when the constant-speed cruise function is started, the preset target vehicle speed is displayed.
For example, as shown in fig. 1, the arrow mark and the bar graph may be applied to point to the target vehicle speed of the instrument panel in real time, or the target vehicle speed may be indicated by a shape change of a reference mark indicating the speed, for example, as shown in fig. 4, the current target vehicle speed is indicated by a change of a thickness of a scale line indicating the target vehicle speed.
And S102, detecting whether the vehicle meets a constant-speed cruising condition or not according to the actual vehicle speed and the target vehicle speed.
It is understood that, in the actual operation of the vehicle, the state of the vehicle is changed in real time, and the entering of the constant-speed cruise state to enable the vehicle to operate at the target vehicle speed is actually required for the state of the vehicle, so that, in order to avoid the vehicle from entering the constant-speed cruise state to cause vehicle failure when the actual operation state of the vehicle is not suitable for entering the constant-speed cruise system, in the embodiment of the present invention, whether the vehicle meets the constant-speed cruise condition is detected according to the actual vehicle speed and the target vehicle speed.
It should be noted that, according to the difference between the vehicle structure and the operation principle, the constant-speed cruising condition of the vehicle specifically includes different contents, which are exemplified as follows:
in an embodiment of the present invention, an absolute value of a difference between an actual vehicle speed and a target vehicle speed may be detected in real time, and whether the absolute value of the difference is continuously greater than a preset threshold within a preset time period is determined, where the preset threshold may be calibrated according to a specific application scenario, and preferably, the preset threshold is 5KM/h, if it is determined that the absolute value of the difference is continuously greater than the preset threshold within the preset time period, it is detected that the vehicle does not satisfy the cruise condition at a constant speed, and if it is determined that the absolute value of the difference is not continuously greater than the preset threshold within the preset time period, it is detected that the vehicle satisfies the cruise condition at a constant speed, where the preset time period is set according to the application scenario, and preferably, the preset time period is 90S.
In this embodiment, if the difference is a negative value, that is, the actual vehicle speed is lower than the target vehicle speed by a certain value (5 km/h temporarily) and exceeds a certain time, it indicates that the vehicle is in a climbing stage or the entire vehicle has a low battery level or the entire vehicle has a fault such as limited power, and the vehicle cannot reach the target vehicle speed set by the user, and if the cruise control does not exit, dangerous faults such as over-temperature of the motor and over-current of the battery are caused, and therefore, it is determined that the vehicle does not satisfy the cruise control conditions.
If the difference value is a positive value, namely the actual vehicle speed is higher than the target vehicle speed by a certain value and exceeds a certain time, the fact that the vehicle is possibly on a steep downhill road is indicated, at the moment, because the feedback current of the battery is limited, larger braking force can not be guaranteed to be carried out on the vehicle, if the constant-speed cruise is directly quitted, the danger degree is possibly improved under the condition that a user is not aware of the situation, and therefore the vehicle is determined not to meet the constant-speed cruise condition at the moment.
And S103, if the fact that the vehicle does not meet the constant-speed cruising condition is detected and known, prompting the driver to stop the constant-speed cruising function after preset time.
Specifically, if it is detected that the vehicle does not satisfy the constant-speed cruising condition, the driver is prompted to stop the constant-speed cruising after a preset time in order to avoid vehicle failure. The preset time can be determined according to the current road condition and the specific state of the vehicle.
In the actual execution process, different implementation modes can be adopted according to different application scenes to prompt a driver, for example, a bar chart on a constant-speed cruise display interface is subjected to color change display, and/or the bar chart flickers according to a preset frequency, and/or a buzzer sounds to prompt according to a preset frequency in a voice mode, and/or fault information is displayed on an instrument panel in a text prompting mode.
In order to make it more clear for those skilled in the art to understand the process of prompting the driver according to the embodiment of the present invention, the following description will take the example of displaying the fault information through the dashboard as an example.
In this example, a constant speed cruise mode is defined, the associated switch set comprising at least the following faults:
failure of the constant-speed cruise switch group:
a) in the key type cruise switch group, any key except the CANCEL key is pressed for a certain time, which indicates that the switch group is adhered;
b) in the lever-type cruise switch group, the switch states 3 and 4 (wherein, the switch states 3 and 4 are switches which can realize corresponding functions only by pressing for a short time and can rebound to the original position when being pressed) continuously exceed a certain time, which indicates that the switch group is adhered. In the toggle lever type cruise switch SET, if the left knob is in the ON position and the right knob is in the SET/-position, or if the left knob is in the ON position and the right knob is in the RES/+ position, it is also indicated that the switch SET is faulty.
In this example, in order to further increase the man-machine interaction inductance, the ICM should have a constant-speed cruising state reminding function, and display a certain time in the main instrument panel in a large text, so that when the user controls the vehicle to enter the constant-speed cruising mode, the constant-speed cruising function is activated from standby to active, xCU _ a sends a "standby to active" signal to the ICM, the ICM should be able to display an activated message for reminding the user to cruise, such as displaying a "cheer activated" text reminding message, and last a certain time (such as 2s), and further, if the constant-speed cruising mode is exited, the constant-speed cruising function is activated from standby, xCU _ a sends an "activated to standby" signal to the ICM, and the ICM should be displayed a message for reminding the user to cruise and enter the standby message, and last a certain time (such as 2 s).
During the process of entering the constant speed cruise mode, if the cruise is in a standby state, and under any condition, xCU _ A sends a signal of 'constant speed cruise fault' to the ICM, and the ICM is required to display information for prompting a user that the cruise is not available currently after receiving the signal, such as displaying 'switch group fault la' in a main display area as shown in FIG. 2(b), and the like for a certain time (such as 2 s).
The reason for the failure may be any failure in the defined constant-speed cruise mode described in the above embodiments, for example, any key other than the CANCEL key in the push-button cruise switch SET is pressed, for example, in the lever cruise switch SET, the left knob is in the ON position, and the right knob is in the SET/-position, or the left knob is in the ON position, and the right knob is in the RES/+ position, such as other failures not listed in the constant-speed switch SET.
Certainly, in the actual driving process, a user may not actively stop the constant-speed cruise function after the preset time in time, at this time, in order to avoid vehicle faults, when the preset time is reached, the prompt is stopped and whether the constant-speed cruise function is closed by the driver is detected, and if the constant-speed cruise function is detected not to be closed, the constant-speed cruise function is controlled to be exited.
Based on the above embodiments, in this example, in order to increase the interaction with the user, some information in the constant speed cruise process is displayed through the display interfaces shown in fig. 1 and fig. 2(a), where the information defined in the following table 1 is interacted with respect to the man-machine interaction of the constant speed cruise, where the VCU in table 1 is a vehicle control unit and is responsible for sending information related to the constant speed cruise to the meter, and the ICM is an intelligent meter and is responsible for displaying information related to the constant speed cruise.
TABLE 1
In order to make the constant-speed cruise safety control method more clear to those skilled in the art, the following description is made with reference to the display information of the constant-speed cruise safety control method on the relevant display interface:
specifically, after the constant-speed cruise function is started, the indicator light of the constant-speed cruise function is turned on, namely, the light is turned on when the constant-speed cruise is in a standby or activated state, as shown in fig. 1, after the constant-speed cruise function is started, a target vehicle speed small arrow and a target vehicle speed bar graph point to a target vehicle speed set by a user in real time, when any scene appears, the target vehicle speed bar graph is changed into yellow and flickers at a certain frequency to prompt the user that the constant-speed cruise is about to exit, the constant-speed cruise is temporarily flickered for 10S, and if the user does not actively exit the constant-speed cruise within 10S, the VCU controls the constant-speed.
(a) The actual vehicle speed is lower than the target vehicle speed by a certain value, such as 5km/h), and exceeds a certain time (such as 90S);
(b) the actual vehicle speed is higher than the target vehicle speed by a certain value (5 km/h temporarily) and exceeds a certain time (90S temporarily);
condition (a) occurrence scenario: when the vehicle is in a climbing stage or the whole vehicle has low battery power or the whole vehicle has faults such as limited power and the like, the vehicle cannot reach the target vehicle speed set by a user, and dangerous faults such as over-temperature of a motor, over-current of a battery and the like can be caused if the vehicle does not exit during constant-speed cruising.
Condition (b) occurrence scenario: the vehicle is positioned on a steep downhill road, the battery feedback current is limited at the moment, larger braking force can not be guaranteed to be applied to the vehicle, if the vehicle is directly withdrawn during constant-speed cruising, the danger degree can be improved under the condition that a user is not aware of the situation, and the method is realized by flickering the target vehicle speed and then actively withdrawing, so that the fault is avoided and the man-machine interaction inductance is improved.
Wherein, when the constant-speed cruise is from standby to active, the main display area of the instrument displays that the cruise set speed is XXXkm/h as shown in figure 1; when the constant-speed cruise is changed from active to standby, the meter main display area displays "cruise condition is not satisfied" as shown in fig. 2 (a). The display time is 2S, and the actual vehicle speed display is recovered after 2S.
Therefore, the constant-speed-cruise safety control method provided by the embodiment of the invention not only provides man-machine interaction inductance for constant-speed cruise, but also can cause some unexpected faults if the constant-speed cruise is started all the time when the vehicle has the scenes of limited power, low battery power, large gradient or steep slope and the like from the perspective of the safety of the whole vehicle.
In summary, in the cruise control method according to the embodiment of the present invention, the cruise control function is started, the preset target vehicle speed is displayed, whether the vehicle meets the cruise control condition is detected according to the actual vehicle speed and the target vehicle speed, and if it is detected that the vehicle does not meet the cruise control condition, the driver is prompted to stop the cruise control function after the preset time. Therefore, the man-machine interaction inductance of the constant-speed cruise is improved, and the safety of the constant-speed cruise is enhanced.
