In some cases, carry out speed of a motor vehicle adjustment by the second maximum speed limit on speed limitation board, alsoMay run into following problem: in some turning sections, may place speed limitation board " 40 ",After the detour past, may not cancel the mark of speed limit, if therefore always according to speed limit 40Travel, can make troubles to driver. Therefore, for example, for some special speed limits,The speed limit that speed limit " 40 " is following, in city, its speed limit distance can not be very long, is therefore necessaryAdjust by these features. Therefore, in one embodiment of the invention, also comprise:If being described the second maximum speed limit, described current maximum speed limit (can also further limit herein,The number range of fixed the second maximum speed limit, for example, be less than 40, because speed limit is less than 40 section notCan be very long, if the section of speed limit 80 may be whole piece highway, can be very long), meterCalculate the enforcement distance under described current maximum speed limit, if described enforcement distance is greater than distanceThreshold value (for example 500 meters or 2000 meters), the section that is inferred as so speed limitation board is passed throughGone, cancelled the second maximum speed limit on this speed limitation board, automobile itself is set described theOne maximum speed limit is as described current maximum speed limit. Like this, just avoid having passed through limitThe problem of also travelling according to the speed of speed limitation board after the speed-limit road section of speed board.
In described step 101, Negotiation speed is set button and is set described the first maximum speed limit,If do not set described the first maximum speed limit, while enforcement by the last time in read memorySetting value is obtained described the first maximum speed limit.
