Background technology
Constant speed cruising system (CRUISE CONTROL SYSTEM, CCS), also known as cruise mobile devices, speed control
System processed, automated driving system etc..After the speed combination switch of driver requests, car is just automatically kept without accelerator pedal
Speed, makes vehicle be travelled with fixed speed.This device is employed, after driving a vehicle for a long time on a highway, driver is just not
With going to control gas pedal again, fatigue is alleviated, while reducing unnecessary speed change, fuel can be saved.Thus, tool
There are wide market prospects.This system is abroad on automobile using more, and in the U.S., installation rate has reached more than 60%.So
And, in China because road conditions are limited, utilization rate is not high.Even if the system breaks down, driver also pays no attention to.In addition,
Due to maintenance technique can not with automotive engineering synchronously develop rapidly, many maintenance personals still understand systematicly deficiency to this so that
The system is interfered or damaged unintentionally in maintenance process, it is impossible to phenomenon of the failure, accurate failure judgement root is analysed scientifically
Source.
With continuing to develop for automotive engineering, current cruise is broadly divided into three major types：Mechanical pulling cruise
Device (is applied to the vehicle that accelerator mode control uses mechanical pulling to control), and electronic type constant-speed cruising equipment (is applied to throttle control

Analyze by inquiry, when and where constant speed cruising system is not all suitable for.Professional person represents：Constant speed is patrolled in principle
Boat will be used on highway or totally-enclosed road.Because on non-close road, complicated road conditions are unfavorable for traffic safety.For example
On national highway, some tractor dynamic powers are not enough, can cause obstacle to cruise vehicle；Often there is vehicle punching at many small crossings again in addition
Upper road surface, in the case of cruise, is easily caught unprepared, and the constant speed that can not also keep stable of being braked repeatedly on national highway
Cruising condition, loses the meaning of constant speed.In addition, cruise must be used when winding road or excessive detour with caution.Because just
In the case of often going out detour, suitably to refuel and bigger steering force is provided, and vehicle maintains speed automatically under constant speed cruising condition
Constant, throttle often brings danger by car running computer control to detour driving, under these conditions, should suitable control speed,

The whole schematic diagram of velocity modulation example shown in Figure 5.
" upward " or " downward " key 3-5 seconds are pressed, into cruise (it is required that ECU obtains GES ＞ 40km/h).
" upward " is pressed again, increases speed per hour；" downward " is pressed again, speed per hour (can press or long-press) is reduced.
2nd, cruise reset/closing (CRUISE RES/SET) switch, the wiring diagram for the reset/closing switch that cruises is referring to Fig. 6
Shown example (cruise reset/closing), the schematic diagram of reset/closing of cruising example shown in Figure 7.
Press downwards, the cruise speed per hour set before recovery；Press upwards, terminate cruise.
3rd, touch on the brake, stepping on clutch, step on the gas：Cruise can be exited.
(2), note：
Such as above switch fault or clamping stagnation or GES are inaccurate or press more than 2 cruise switches simultaneously, can all lead
Cause cruise failure；Such as gradient is larger, or road conditions are poor, can also exit cruise.
In a specific example, the entrance of cruise：Driver hang 5 grades and more than, speed be more than or equal to 30km/h, engine
Rotating speed in the range of 600~2800rpm, press cruise " plus " key or " subtracting " key, you can enter cruising condition.The tune for speed of cruising
It is whole：Into after cruise, can with cruise " plus " key or " subtracting " key, carry out the increase and decrease of cruise speed, often click on once cruise " plus ",
Speed lifts 2km/h, often clicks on once " subtracting ", speed reduction 2km/h；Long-press cruise " plus ", speed lifting 1.5km/h/s, length
By cruise " subtracting ", speed reduction 1.5km/h/s.
In the specific example, cruise is exited：1) cruise can be exited by stepping on clutch, braking, exhaust brake, preceding
Carry is that each correspondence switching signal has accessed ECU.After this method cruise is exited, directly it can recover cruising condition by resetkey, it is preceding
Carry is by still meeting cruise activation condition when resetkey.2) cruise can also be exited with cruise "close" key, but with such a
Method is exited after cruise, and cruise can not be entered back into by resetkey.The key activation cruise that adds deduct need to be pressed again.3) stepped on using throttle
Plate can also temporarily exit cruise.The demand for example, driver overtakes other vehicles under cruising condition, driver can be with open up the engine, ECU
If detecting throttle signal during cruise, cruise moment of torsion and pedaling torque can be compared, take higher value, to meet
Moment of torsion during cruise (is such as overtaken other vehicles) demand and accelerated, and unclamps after gas pedal, cruising condition is not exited, and is continued to original and is patrolled
Boat state.
