Further, after driver presses RES+ key, i.e. driver's current goal speed for needing to be promoted vehicle is fixed
Speed cruise key parsing module meeting real-time detection push button signalling, and judge whether it is short-press push button signalling, for example, if it is less than
0.5s then detects it is short-press push button signalling, then carries out corresponding acceleration and adjusts.
First determine whether current goal cruise speed is less than or equal to cruise upper limit speed (such as 130km/h) and 1km/
The difference of h, if satisfied, then continuing to judge whether short-press key counter reaches upper limit value, if short-press key counter is not up to
Current goal cruise speed is then increased 1km/h by limit value, if short-press key counter reaches counter upper limit value, holding is worked as
Preceding target cruise speed is constant.
Wherein, count upper-limit value is according to actual vehicle speed dynamic change, for example, (1) when cruise lower limit speed (such as
40km/h)≤actual vehicle speed≤80km/h when, counter upper limit value can be set to 15；(2) when 80km/h < actual vehicle speed≤
When 100km/h, counter upper limit value can be set to 12；(3) when 100km/h < actual vehicle speed≤cruise upper limit speed (such as
When 120km/h), counter upper limit value can be set to 8.Above-mentioned to be intended only as example, those skilled in the art can be according to reality
Border situation is configured, and is not specifically limited herein.
Further, in one embodiment of the invention, the method for the embodiment of the present invention further include: when lasting triggering
Between less than the second preset value when, maintain current goal cruise speed, wherein the second preset value is less than the first preset value.
It is understood that the second preset time can be 0.2s, those skilled in the art can according to the actual situation into
Row setting, herein only as an example, being not specifically limited.When being less than 0.2s in the lasting triggered time of key, without accelerating
Or the adjusting slowed down, maintain current goal cruise speed.
For example, when vehicle is in cruise, driver may accidentally touch cruise key, and the present invention is implemented
Example passes through the lasting triggered time of capture button, when being less than 0.2s, adjusts without speed, to effectively avoid leading because accidentally touching
It causes vehicle cruise speed to change, effectively improves driving experience.
In step s 103, if continuing the triggered time is greater than the first preset value, and meet the obtained by current vehicle speed
The current goal cruise speed of vehicle is then reduced/is increased key speed offset, otherwise maintains to work as by two decelerations/acceleration environment
Preceding target cruise speed.
It is long-pressing push button signalling when it is understood that continuing the triggered time greater than the first preset value, for example, working as driver
After pressing SET- key or RES+ key, cruise key parsing module meeting real-time detection push button signalling, if lasting touching
The time is sent out greater than the first preset value, then judgement is long-pressing push button signalling.
Further, in one embodiment of the invention, wherein the second deceleration conditions are that current goal cruise speed is big
In or equal to cruise the sum of lower limit speed and key speed offset；Second acceleration environment be current goal cruise speed be less than or
Equal to the difference of cruise upper limit speed and key speed offset, wherein preset vehicle speed offset is obtained according to current vehicle speed.
Specifically, the case where current goal cruise speed is accelerated and slowed down below is explained in detail respectively.
After driver's long-pressing SET- key, i.e., driver need to reduce vehicle current goal cruise speed, such as Fig. 2 institute
Show, if detecting is long-pressing push button signalling, in each cruise control algorithm execution time (such as 50ms), first determines whether to work as
Preceding target cruise speed whether be more than or equal to cruise lower limit speed (such as 40km/h) and long-pressing key speed offset and, if
Meet, then current goal cruise speed is reduced into long-pressing key speed offset, if not satisfied, then keeping current goal cruise vehicle
Speed is constant.
As shown in figure 3, the value of above-mentioned long-pressing key speed offset is given below according to actual vehicle speed dynamic change
A kind of specific implementation, but not limited to this scheme.It specifically includes:
(1) when cruise lower limit speed (such as 40km/h)≤actual vehicle speed≤80km/h when, long-pressing key speed offset
It is set as 0.6km/h~0.2km/h.
(2) as 80km/h < actual vehicle speed≤100km/h, long-pressing key speed offset be set as 0.2km/h~
0.08km/h。
(3) as 100km/h < actual vehicle speed≤120km/h, long-pressing key speed offset be set as 0.08km/h~
0km/h。
The embodiment of the present invention can be arranged different by using long-pressing key speed offset and for each speed section
Long-pressing key speed offset value is excessive to avoid driver's long-pressing key that target cruise speed is caused to change, especially in high speed
When high speed cruise drives on highway, target cruise speed changes the excessive influence caused to front truck and rear car greatly, thus
Reduce the risk that safety accident occurs.
When long-pressing SET- key, (such as 50ms) is to target cruise speed in each cruise control algorithm execution time
Reduce speed offset value, which is a fractional value, and above-mentioned Processing Algorithm presence makes target cruise speed
Possibility containing fractional value is pressed in the embodiment of the present invention by introducing long-pressing to allow target cruise speed to remain integer value
Key speed rounding-off compensation upper limit value to carry out rounding treatment to target cruise speed:
(1) if the fractional part of target cruise vehicle speed value be less than or equal to long-pressing key speed rounding-off compensation upper limit value (such as
0.9km/h), then target cruise speed uses its integer part；
(2) if the fractional part of target cruise vehicle speed value be greater than long-pressing key speed rounding-off compensation upper limit value (such as
0.9km/h), then target cruise speed uses its integer part+1km/h.
For example, when driver's long-pressing SET- key reduces target cruise speed, actual vehicle speed is also correspondingly declining,
If target cruise speed is reduced to 80.6km/h, and actual vehicle speed also drops to 80.6km/h, if right when unclamping SET- key
Target cruise speed use rounds up mode, then obtaining target cruise speed is 81km/h, and actual vehicle speed can be from this time
80.6km/h accelerates to 81km/h, when unclamping the stopping deceleration of SET- key, hastening phenomenon occurs, and the embodiment of the present invention passes through
The fractional part of target cruise speed is handled, is less than or equal to the long-pressing key speed rounding-off compensation upper limit in fractional part
When value 0.9km/h, give up fractional part, to avoid occurring apparent acceleration situation, effectively promotion driving experience when slowing down.
Further, after driver's long-pressing RES+ key, i.e. driver's current goal speed for needing to be promoted vehicle, if
It detects it is long-pressing push button signalling, then in each cruise control algorithm execution time (such as 50ms), first determines whether current mesh
Whether mark cruise speed is less than or equal to the difference of cruise upper limit speed (such as 130km/h) and long-pressing key speed offset, if full
Current goal cruise speed is then increased long-pressing key speed offset by foot, if not satisfied, then keeping current goal cruise speed
It is constant.
As shown in figure 3, the value of above-mentioned long-pressing key speed offset is given below according to actual vehicle speed dynamic change
A kind of specific implementation, but not limited to this scheme.It specifically includes:
(1) when cruise lower limit speed (such as 40km/h)≤actual vehicle speed≤80km/h when, long-pressing key speed offset
It is set as 0.6km/h~0.2km/h.
(2) as 80km/h < actual vehicle speed≤100km/h, long-pressing key speed offset be set as 0.2km/h~
0.08km/h。
(3) as 100km/h < actual vehicle speed≤120km/h, long-pressing key speed offset be set as 0.08km/h~
0km/h。
Different long-pressings is arranged by using long-pressing key speed offset and for each speed section in the embodiment of the present invention
Key speed offset value, thus effectively avoid driver's long-pressing key that target cruise speed is caused to change excessive situation, it is special
When not being high speed cruise driving on a highway, target cruise speed, which changes, excessive to be caused greatly front truck and rear car
It influences, to reduce the risk of safety accident generation.
When long-pressing RES+ key, (such as 50ms) is to target cruise speed in each cruise control algorithm execution time
Increase speed offset value, which is a fractional value, and above-mentioned Processing Algorithm presence makes target cruise speed
Possibility containing fractional value passes through introducing long-pressing key speed in the present invention to allow target cruise speed to remain integer value
Rounding-off compensation lower limit value to carry out rounding treatment to target cruise speed:
(1) if the fractional part of target cruise vehicle speed value be more than or equal to long-pressing key speed rounding-off compensation lower limit value (such as
0.1km/h), then target cruise speed uses its integer part+1km/h；
(2) if the fractional part of target cruise vehicle speed value be less than long-pressing key speed rounding-off compensation lower limit value (such as
0.1km/h), then target cruise speed uses its integer part.
For example, when driver's long-pressing RES+ key increases target cruise speed, actual vehicle speed is also correspondingly increasing,
If it is 90.4km/h that target cruise speed, which increases, and actual vehicle speed is also added to 90.4km/h, if right when unclamping RES+ key
Target cruise speed use rounds up mode, then obtaining target cruise speed is 90km/h, and actual vehicle speed can be from this time
90.4km/h decelerates to 90km/h, when unclamping the stopping acceleration of SET- key, deceleration phenomenon occurs, and the embodiment of the present invention passes through
The fractional part of target cruise speed is handled, is more than or equal to long-pressing key speed rounding-off compensation lower limit value in fractional part
When 0.1km/h, target cruise speed uses its integer part+1km/h, so that the case where slowing down when accelerating effectively is avoided,
Effectively promote driving experience.
Further, in one embodiment of the invention, the method for the embodiment of the present invention further include: detection cruise key
Triggering number；When it is multiple for triggering number, using the cruise key of highest priority as the cruise key of triggering, wherein
When the key of equal priority is pressed simultaneously, current goal cruise speed is maintained.
It is understood that the cruise key of the embodiment of the present invention can be pressed for ONOFF key, CANCEL key, SET-
Key, RES+ key, and in view of driver presses the maloperation situation of multiple keys simultaneously, the embodiment of the present invention can be to cruise
Key carries out priority distribution, is specifically allocated as follows:
(1) ONOFF key: high priority；
(2) CANCEL key: middle priority；
(3) SET- key or RES+ key: low priority.

Answer the processing of high priority key.When the key for detecting same priority while when pressing, i.e., it ought detect while press
When SET- key and RES+ key, then without any processing.
Further, as shown in figure 5, the cruise of embodiment is managed using multiple modes in the present invention, when patrolling
When boat system enters CRUISE_RESUME mode from CRUISE_CANCEL mode or CRUISE_OVERRIDE mode, if
Driver presses SET- key or RES+ key under CRUISE_RESUME mode, then carries out corresponding CRUISE_RESUME mode
Under algorithm process, detailed algorithm is as follows:
(1) detect SET- by key pressing:
If a, short-press SET- key, target cruise speed reduces 1km/h；
If b, long-pressing SET- key, and SET- key is unclamped before actual vehicle speed is restored to target cruise speed, then with reality
Border speed updates target cruise speed；
If c, long-pressing SET- key, and still press SET- key after actual vehicle speed is restored to target cruise speed, then exist
(such as 50ms) reduces long-pressing key speed offset to target cruise speed in each cruise control algorithm execution time.
(2) detect RES+ by key pressing:
If a, short-press RES+ key, target cruise speed increases 1km/h；
If b, long-pressing RES+ key, and RES+ key is unclamped before actual vehicle speed is restored to target cruise speed, then to mesh
