Detailed Description
Embodiments of the present invention will be described in detail below, the embodiments described with reference to the drawings being illustrative, and the embodiments of the present invention will be described in detail below.
A method of controlling a vehicle cruise at a constant speed according to an embodiment of the present invention is described below with reference to fig. 1-2, where the vehicle may include a balance car, an electric motorcycle, a kart, or other vehicle with cruise at a constant speed.
Fig. 1 is a flowchart of a method of controlling a vehicle cruise control according to an embodiment of the present invention, and as shown in fig. 1, the method of controlling a vehicle cruise control according to the embodiment of the present invention includes at least the following steps S1-S4.
In step S1, a speed adjustment trigger is received in the cruise mode.
In an embodiment of the invention, the vehicle is provided with a triggering unit for adjusting the cruise speed set value, which may be implemented in the form of a key or knob or touch control, or by using the throttle knob of the vehicle, or in other feasible forms. The triggering unit can be a unit specially used for speed adjustment in the constant-speed cruise mode on the vehicle, and can also be an existing triggering unit on the vehicle, namely the triggering unit is a unit which is reused as the speed adjustment in the constant-speed cruise mode, so that the hardware of the vehicle is not required to be changed, and the time and the labor are saved.
In some embodiments, in the cruise mode, a trigger signal of a trigger unit of the vehicle is received, i.e. it is determined that a speed adjustment trigger action is detected. For example, in a cruise mode, a trigger signal of a unit of the vehicle multiplexed as a speed adjustment is received, i.e. it is determined that a speed adjustment trigger action is detected.
In some embodiments, the trigger unit for adjusting the speed in the constant-speed cruise mode may multiplex an operation mode switching unit of the vehicle for switching operation modes of the vehicle such as an energy-saving mode, a comfort mode, a sport mode, and the like. And receiving a trigger signal of the operation mode switching unit, namely determining that the speed regulation trigger action is detected.
For example, fig. 2 is a schematic view of a partial structure of an electric motorcycle according to an embodiment of the present invention, wherein an operation MODE switching unit 10 including a MODE downshift button 101 and a MODE upshift button 102 is disposed at a handlebar portion of the electric motorcycle. When the MODE downshift key 101 or the MODE upshift key 102 is operated according to a set action, a corresponding trigger signal is generated, and in a constant-speed cruise MODE, the controller receives the trigger signal, namely detects a speed adjustment trigger action.
In step S2, the current cruise speed set point is determined based on the speed adjustment trigger action.
For example, as shown in fig. 2, when the vehicle is in the non-cruise MODE, the MODE upshift and downshift key may be triggered to switch between different operation MODEs, so as to provide different driving experiences; when the vehicle is in a constant-speed cruise MODE, the MODE plus and minus gear key is triggered to adjust a cruise speed set value.
In some embodiments, for a key-form trigger unit, the speed adjustment trigger action may include a short press or a long press, etc.; for the touch-control type trigger unit, the speed adjustment trigger action may include point touch or sliding.
In an embodiment, a corresponding regulation rule of the speed regulation trigger action and the cruise speed set value may be set, and when the speed regulation trigger action is detected, the cruise speed set value may be regulated according to the corresponding rule.
In step S3, the vehicle is controlled to travel according to the cruise speed set value after determination. And the actual cruising speed of the vehicle speed can transit to the determined cruising speed set value, thereby realizing the change of the cruising speed set value in the constant-speed cruising mode.
According to the method for controlling the constant-speed cruising of the vehicle, disclosed by the embodiment of the invention, based on the special or multiplexing trigger unit, the current cruising speed set value is determined according to the detected speed regulation trigger action in the constant-speed cruising mode, and then the actual speed of the vehicle can be transited to the cruising speed set value and cruise at the constant speed according to the set value, so that the cruising speed set value is adjusted in the constant-speed cruising mode, the requirement of a user for changing the cruising speed in the constant-speed cruising mode is met, the cruising speed regulation can be realized by operating the trigger unit, the operation is simple, and the user experience is improved.
In some embodiments, for triggering the vehicle cruise control mode, as shown in fig. 2, the vehicle includes a cruise trigger unit 20, in the non-cruise control mode, the actual speed of the vehicle is obtained, the actual speed of the vehicle is greater than a cruise speed threshold value, and the vehicle is controlled to enter the cruise control mode by detecting a trigger signal of the cruise trigger unit 20, and the vehicle keeps running at a constant speed. The driving motor of the Hall switch is arranged, so that the speed control is unstable at low speed, and therefore, when the actual speed of the vehicle is greater than a set threshold value, namely a cruise speed threshold value, for example, 10Km/h, the cruise trigger unit 20 is operated, the whole vehicle enters a constant-speed cruise mode, the cruise speed is more stable, and the constant-speed cruise experience is improved.
For some users with special hobbies or some 'obsessive-compulsive disorders', the cruise speed is strongly required to be a certain value, for example, the cruise speed setting value is required to be multiple of 5 or even, in the cruise mode in the related art, the user demand can be met only by accurately adjusting the vehicle speed and triggering the cruise, and the cruise mode is not flexible enough and intelligent enough, so that the user experience is influenced. In order to solve the problem, according to the method for controlling the vehicle cruise at the constant speed, the current cruise speed set value is determined according to the speed regulation trigger action based on the set cruise speed regulation rule, so that the requirement of a user for changing the cruise speed to a desired speed value in the constant-speed cruise mode is met, and the user experience is improved.
The process of adjusting the current cruise speed set point based on the speed adjustment trigger action is described below.
In some embodiments, a speed adjustment trigger action is detected, and the duration of the speed adjustment trigger action is recorded; when the duration is less than the first time threshold value, for example, 1 second, the current cruise speed set value is adjusted to the adjacent target cruise speed value, where the target cruise speed set value is a numerical value that satisfies a preset rule, for example, the target cruise speed set value is an odd number, an even number, or a multiple of a certain number, or is rounded to a certain number, or satisfies other set rules, so that the requirements of users who have requirements on speed values can be satisfied, and the user experience is improved.
In some embodiments, the target cruise speed set point that is closest to the current cruise speed set point includes a first target cruise speed set point and a second target cruise speed set point. When the current cruise speed set value is adjusted to the nearest target cruise speed set value, and when the current cruise speed set value is increased, if the current cruise speed set value is larger than the nearest first target cruise speed set value and smaller than the nearest second target cruise speed set value, adjusting the current cruise speed set value to the second target cruise speed set value; or, when the current cruise speed set value is decreased, if the current cruise speed set value is greater than the nearest first target cruise speed set value and less than the nearest second target cruise speed set value, the current cruise speed set value is adjusted to the first target cruise speed set value. And then the actual speed of the vehicle in the constant-speed cruise mode is transited to the cruise speed set value and the vehicle cruises at the constant speed by the set value, so that the cruise speed set value is adjusted in the constant-speed cruise mode, and the requirement of a user for changing the cruise speed in the constant-speed cruise mode is met.
Taking an electric motorcycle as an example, as shown in fig. 2, a triggering unit for adjusting a cruise speed set value multiplexes operation MODE switching units of a vehicle, including a MODE downshift key 101 and a MODE upshift key 102. For example, by pressing MODE upshift key 102 for a short time, the current cruise speed is increased by 5Km/h and rounded for 5. Specifically, in the constant-speed cruise MODE, the MODE upshift key 102 is pressed for a period less than t1, for example, 1 second, at the moment of releasing the MODE upshift key 102, if the current cruise speed set value is a multiple of 5, the current cruise speed set value is increased by 5Km/h, otherwise, the current cruise speed set value is rounded to 5, for example, at this time, the vehicle speed, that is, the current cruise speed set value is 12Km/h, and the set cruise speed value nearest to the current cruise speed set value is between 10Km/h and 15Km/h, and due to the upshift operation, the current cruise speed set value is adjusted to 15 Km/h. Thus, it is possible to satisfy the user's demand for the constant-speed-cruise speed value to be a multiple of 5 in the constant-speed-cruise mode.
In other embodiments, the current cruise speed set point is increased or decreased according to a certain set speed amplitude, specifically, a speed adjustment trigger action is detected, and the duration of the speed adjustment trigger action is recorded; and controlling the current cruise speed set value to increase or decrease the first speed amplitude when the duration is less than the first time threshold. For example, when the trigger key is pressed for a short time or the speed control is touched, each time the key is triggered, namely the current cruise speed set value is adjusted to be increased or decreased once, the change range is a first speed amplitude value, for example, 1km/h, and the cruise speed set value is sequentially increased or decreased according to the operation instruction. And then the actual speed of the vehicle is transited to the cruise speed set value, so that the cruise speed is changed in the constant-speed cruise mode.
In some embodiments, the duration of the speed adjustment trigger action is recorded, and the duration is greater than or equal to a first time threshold, for example, the current cruise speed value is adjusted every preset time when the trigger button is pressed or slid for a long time, wherein the longer the duration, the more the difference between the current cruise speed setting and the user desired speed value is, the smaller the preset time for adjusting the interval of the current cruise speed setting is, so that the cruise speed setting can be adjusted to the user desired speed setting more quickly.
Still taking an electric motorcycle as an example, as shown in fig. 2, when the MODE upshift key 102 is operated, the current cruise speed set value is increased by 1Km/h when the pressing time is longer than t1, for example, t1 is 1s, and then increased by 1Km/h every t2, where t2 may also be 1s, and when the current cruise speed set value is accumulated over N, for example, 5Km/h, or the duration of the trigger action exceeds a certain value, the current cruise speed set value is increased by 1Km/h every t3, and t3 is smaller than t1, for example, t3 is 0.5s, until the key is released.
In the embodiment of the invention, under the constant-speed cruise mode, the control of the accelerator handle is also limited, specifically, the rotation angle of the accelerator handle of the vehicle is detected when the vehicle is under the constant-speed cruise mode; obtaining a speed instruction value according to the rotation angle; the speed instruction value is smaller than the current cruise speed set value, and the vehicle is controlled to run according to the current cruise speed set value; or the speed instruction value is larger than or equal to the current cruise speed set value, and the vehicle is controlled to run according to the speed instruction value.
For example, still taking an electric motorcycle as an example, after entering a constant-speed cruise mode, the vehicle runs at a constant speed, such as V1, in which a user turns an accelerator knob, and a rotation angle of the accelerator knob corresponds to a speed command value, such as V2, and as the rotation angle of the accelerator knob increases, V2 gradually increases, and when V1> V2, the vehicle keeps running at a current speed V1; when V2 is greater than V1, the control of an accelerator handle is switched on, and the vehicle accelerates; when the throttle handle rotation angle is reduced again until V1> V2, the vehicle decelerates to V1 and keeps constant speed.
In some embodiments, after determining the current cruise speed set point, the determined cruise speed set point is prompted so that the user can learn the current cruise speed set point of the vehicle in a timely manner. For example, after the current cruise speed set value is adjusted, a specific area of an instrument of the electric motorcycle reminds a user of the current cruise speed set value, so that the user can know the current cruise speed set value in time.
