Detailed Description
In order to enable a person skilled in the art to better understand the technical solutions of the present application, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.
It should be noted that the terms "first," "second," and the like in the description and the claims of the present application and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the application described herein may be implemented in sequences other than those illustrated or otherwise described herein. The implementations described in the following exemplary examples do not represent all implementations consistent with the application. Rather, they are merely examples of apparatus and methods consistent with aspects of the application as detailed in the accompanying claims.
When the vehicle is in a constant-speed cruising state, the ECU (Electronic Control Unit ) calculates a current virtual accelerator pedal signal according to a cruising vehicle speed set by a current user, and sends the current virtual accelerator pedal signal to an automatic transmission TCU (Transmission Control Unit, automatic gearbox control unit) through a CAN (Controller Area Network) line, and the TCU compares the virtual accelerator pedal signal sent by the ECU and the current vehicle speed with a gear shifting line in the TCU to judge whether gear shifting is performed or not.
However, in the actual running process of the vehicle, the working condition of the vehicle is changed, so that the load of the vehicle is changed, and the value of the virtual accelerator pedal signal is increased or decreased.
In the related art, during the gear shifting of the TCU, the hysteresis rotation speed of a gear shifting point is increased, and under the condition that the gear shifting position meets the gear shifting condition, the TCU controls the vehicle to shift gears. Or, the TCU determines whether the obtained driving force satisfies the required driving force according to the maximum torque after the gear shift, thereby determining whether the vehicle needs the gear shift. However, these methods still suffer from frequent vehicle shifting as long as the vehicle parameters meet the conditions.
Based on the above, the embodiment of the application provides a control method for constant-speed cruising, which can control a vehicle to enter into gear shifting control when the cruising speed is in a preset speed range and the gear shifting times in a preset duration are equal to the preset gear shifting times when the vehicle is detected to be in a constant-speed cruising mode, and further, control the vehicle to run according to the gear shifting gear and the maximum gear in a set gear after the vehicle enters into gear shifting control. Therefore, the gear shifting times of the vehicle in the constant-speed cruising mode are effectively reduced, and the user experience is improved.
For easy understanding, the following describes the control method of constant speed cruising provided by the application with reference to the accompanying drawings.
Fig. 1 is a flowchart showing a control method of a constant speed cruise according to an exemplary embodiment, and the control method includes the steps of:
s101, when the control device detects that the vehicle is in a constant-speed cruising mode, the cruising speed of the vehicle and the gear shifting times within a preset time period are obtained.
The constant-speed cruise mode is a mode in which the vehicle is driven at a cruise vehicle speed set by a user, without requiring the user to manipulate the opening degree of the accelerator pedal. For example, the user-set cruise vehicle speed is 40Km/h.
In some embodiments, shifting once refers to a shift of the vehicle from a current first gear to a second gear and then from the second gear to the first gear.
For example, if the first gear is three and the second gear is four, shifting once means that the gear is shifted up from three to four and then shifted down from four to three. Or if the first gear is the fourth gear and the second gear is the third gear, the shifting is performed once by reducing the fourth gear to the third gear and then increasing the third gear back to the fourth gear.
In some embodiments, there is a first key, a second key, and a third key associated with a constant speed cruise mode on a steering wheel of the vehicle. The first key may be called a cruise main switch key for turning on or off a cruise function, the second key may be called a SET-key for setting a cruise speed, and the third key may be called a res+ key for recovering the cruise function.
In some embodiments, the control device may detect whether the vehicle is in the cruise control mode by detecting whether the user has activated the first key and the second key, or whether the user has activated the third key.
In some embodiments, the control device acquires a cruising speed of the vehicle and a shift number within a preset time period when detecting that the vehicle is in the constant speed cruising mode.
Alternatively, the cruising speed of the vehicle may be obtained by a speed sensor, a rotation speed sensor, etc. of the vehicle, and the preset duration is preset according to the actual running condition of the vehicle.
S102, when the cruising speed is in a preset speed range and the gear shifting times are equal to the preset gear shifting times, the control device controls the vehicle to enter gear shifting control.
The preset gear shifting times can be 2 times, the lower limit of the preset vehicle speed range is the difference value between the cruising vehicle speed and the preset threshold value, and the upper limit of the preset vehicle speed range is the sum of the cruising vehicle speed and the preset threshold value. Wherein the preset threshold may be 2Km/h.
By way of example, if the preset threshold is 2Km/h and the cruise vehicle speed is 40Km/h, the preset vehicle speed range is [38Km/h,42Km/h ].
In some embodiments, the control device controls the vehicle to enter the shift control when the cruise vehicle speed is within a preset vehicle speed range and the shift number is equal to the preset shift number.
In the actual running process of the vehicle, the cruise vehicle speed set by the user fluctuates within a certain range along with the change of the running condition of the vehicle. Therefore, the condition that the above-described cruise vehicle speed is within the preset vehicle speed range means that the cruise vehicle speed is maintained within the preset vehicle speed range.
For example, if the cruise vehicle speed is maintained within the preset vehicle speed range at all times, the cruise vehicle speed satisfies the condition that the cruise vehicle speed is within the preset vehicle speed range. If the cruising speed is not in the preset speed range at a certain moment, the cruising speed does not meet the condition that the cruising speed is in the preset speed range.
S103, after the vehicle enters the gear shifting control, the control device acquires a gear shifting gear of the vehicle and a setting gear of a constant speed cruising mode.
Wherein the shift gear is the second gear in the above step S101, and the shift gear is determined based on any one of a plurality of preset shift maps.
For example, if the gear of the vehicle is shifted up from three to four and down from four back to three, the shift gear is four. For another example, if the gear of the vehicle is shifted down from four to three and up from three to four, the shift gear is three.
The preset gear shifting patterns are used for recording the corresponding relation among the speed of the vehicle, the opening of the accelerator pedal and the gear shifting position, and each preset gear shifting pattern corresponds to one priority.
The shift range can be determined by inquiring a preset shift map based on the vehicle speed and the opening of the accelerator pedal. In addition, the vehicle is pre-stored with a plurality of gear shifting patterns, and the vehicle adopts the gear shifting patterns corresponding to the running conditions according to different running conditions. For example, if the driving condition is an uphill condition, the shift map adopted by the vehicle is a shift map corresponding to the uphill condition. For another example, if the driving condition is a cruising condition, the shift map adopted by the vehicle is a shift map corresponding to the cruising condition.
In some embodiments, the set gear of the cruise control mode is determined based on a preset correspondence between cruise vehicle speed and gear,
exemplary, a preset correspondence between the cruising vehicle speed and the gear is shown in table 1 below.
TABLE 1
It should be noted that the gear is not limited to five gears, and more or fewer gears may be provided according to actual situations, which is not limited to the present application.
In some embodiments, the control device acquires a shift gear of the vehicle and a setting gear of the cruise control mode after the vehicle enters the shift control.
And S104, the control device controls the vehicle to run according to the maximum gear in the gear shifting gear and the set gear.
In some embodiments, the control device determines a maximum gear of the shift gear and the set gear.
For example, if the shift range is four, the set range is three, and the maximum range is the shift range, that is, four. If the gear is three gears and the set gear is four gears, the maximum gear is the set gear, namely the four gears.
Further, the control device controls the vehicle to travel in accordance with the largest gear among the shift gear and the set gear.
For example, if the maximum gear of the shift gear and the set gear is the shift gear, the control device controls the vehicle to travel in accordance with the shift gear. If the maximum gear of the shift gear and the set gear is the set gear, the control device controls the vehicle to travel according to the set gear.
Based on the embodiment shown in fig. 1, the technical solution provided by the embodiment of the present application at least brings the following beneficial effects: according to the embodiment of the application, when the vehicle is detected to be in the constant-speed cruising mode, the vehicle is controlled to enter the gear shifting control when the cruising speed is in the preset speed range and the gear shifting times in the preset duration are equal to the preset gear shifting times, and further, the vehicle is controlled to travel according to the gear shifting gear and the maximum gear in the set gear after the vehicle enters the gear shifting control. Therefore, the vehicle is controlled to run according to a certain gear, the gear shifting times of the vehicle in the constant-speed cruising mode are effectively reduced, and the user experience is improved.
In some embodiments, in order to exit the gear shift control, as shown in fig. 2, the control method for constant speed cruising provided by the embodiment of the application further includes the following steps:
s201, the control device acquires vehicle information.
The vehicle information comprises behavior information of a user, opening of an accelerator pedal and replacement information of a preset gear shifting map.
In some embodiments, the control device further obtains a gradient of the position of the vehicle through a gradient sensor and obtains an ambient temperature through a temperature sensor to determine a driving condition of the vehicle.
And S202, the control device controls the vehicle to exit the gear shifting control when the vehicle information meets the preset condition.
Wherein the preset conditions include any one of the following: the behavior information is the behavior information triggering the operation of exiting the constant-speed cruising mode; the opening of the accelerator pedal is larger than or equal to a preset opening; the replacing information comprises the step of replacing a first preset shifting map adopted by the vehicle with a second preset shifting map, and the priority corresponding to the second preset shifting map is higher than that corresponding to the first preset shifting map.
The behavior information triggering the operation of exiting the constant-speed cruising mode comprises the following steps: the behavior information of pressing the first key, the behavior information of pressing the brake pedal of the vehicle, and the like.
For example, the control device controls the vehicle to exit the shift control in the case where the behavior information is behavior information that triggers the exit from the constant speed cruise mode operation.
Or, the control device controls the vehicle to exit the gear shift control when the opening degree of the accelerator pedal is greater than or equal to a preset opening degree.
Or the control device controls the vehicle to exit the gear shifting control under the condition that the replacement information comprises the replacement of a first preset gear shifting map adopted by the vehicle to a second preset gear shifting map, and the priority corresponding to the second preset gear shifting map is higher than the priority corresponding to the first preset gear shifting map.
