Specific embodiment
The method of the present invention is used for running motor vehicles, and described motor vehicles include explosive motor, described explosive motor with
So-called start-stop-operation or stop-start-operation turn off and start again.Here, being controlled by electromotor controller
Make described explosive motor.
Described explosive motor preferably includes multiple combustor, to described combustor be respectively configured at least one intake valve and
Air bleeding valve.The stroke motion of described valve is controlled by camshaft.Live gass are entered in combustor by described intake valve.
Waste gas passes through described air bleeding valve and discharges from combustor.
By means of camshaft, particularly admission cam shaft described in camshaft adjuster scalable, improve internal combustion to send out
The runnability of motivation, fills combustor especially by intake valve.When adjusting, camshaft rotates the adjustment angle of a determination
Degree.
Described camshaft adjuster for example includes three axle regulate transmission devices with control shaft, described control shaft
By motor-driven.By the phase angle between described motor scalable bent axle and camshaft.
The cartesian coordinate map of Fig. 1 to 4 includes an x-axis 1 and a y-axis 2 respectively.Phase angle is recorded on y-axis 2.
Time is recorded on x-axis 1.Phase angle is represented over time by characteristic curve 4.
Described phase angle is constant and is then reduced in time in relatively small value, described value is if necessary first
It is reduced to zero.By the rotating speed of other characteristic curve 5 record explosive motor relation in time.Described rotating speed reduces first
To zero, because explosive motor is shut down.After connecting explosive motor, described rotating speed raises again.
In time point 11, close breakpoint fire system.In time point 12, explosive motor stops that is to say, that explosive motor
Rotating speed be reduced to zero.In time point 13, send one and allow the instruction that explosive motor starts again.This for example can pass through signal " point
Fire " is realized.
Then, as illustrated by double-head arrow 17, so that electromotor controller is started and start or start.In the time
Point 14, the starting or start of described electromotor controller is terminated.Then, as illustrated by other double-head arrow 18, make
Camshaft regulation-controller starts and starts or start.
Described camshaft regulation-controller is also called NW- controller for short.In time point 15, the sending out of described NW- controller
Dynamic or startup terminates.Then, as shown in by other double-head arrow 19, internal combustion is made to send out by means of starter or starter
Engine start or startup.Here, the bent axle making explosive motor by means of described starter or starter lentamente starts to rotate.
Meanwhile, camshaft adjuster plays its function.Point 10 at realize explosive motor is started favourable
Phase angle or camshaft angle, so that the burning of explosive motor is discharged by electromotor controller in time point 16,
Without negative effect, the igniting of such as fault occur.Then, the rotating speed of explosive motor raises.
In FIG total duration is represented by double-head arrow 20, this total duration is opened from the ignition signal of time point 13
Begin, this total duration is needs for reaching described point 10, described point corresponds to nominal position when burning starts.Pass through
Invention proposes different, measure that is how can reducing described total duration 20.The shortening of described total duration 20 is right
It is conclusive for discovering in the front of the starting process of explosive motor.
Additionally, being imperceptible for driver by the starting process that the measure of the present invention guarantees explosive motor
Or acoustically not noticeable.This is particularly suitable for having the motor-driven of start-stop-system or stop-start-system
Car or hybrid vehicles, in the case of described hybrid vehicles explosive motor with there is conventional internal combustion
The vehicles of electromotor are compared and are fairly frequently started.
Starting conclusive for quick electromotor is the ignition condition it is ensured that good.When valve must be made to control for this
Between reach as quickly as possible by the predetermined time point of engine control system 10.This quick regulation is also to realize discharge most preferably
Operating point precondition.HC and NOx- discharge when explosive motor starts thus can be reduced.
According to an important insight of the present invention, electromotor controller and NW- controller are not one after the other, serially send out
Dynamic, but concurrently start at least in part.That is, being used for making two controllers start the required time to overlap.By
This can reduce to reach the total duration needed for described time point 10.In traditional method shown in Fig. 1, it is used for making two
Controller starts the required time 17 to be added with 18.
According to another viewpoint of the present invention, using following facts：In order to start the persistent period needed for described NW- controller
18 than in order to start the persistent period 17 needed for described electromotor controller short.The starting and NW- control of engine control system
Starting, start or starting of device is slow with 5 to 8 times of the order of magnitude.Its reason particular in that engine control system relatively
High system complexity.
Because the starting process of NW- controller or start or start than the starting process of engine control system or open
Dynamic process or start fast, the therefore another viewpoint according to the present invention, purposefully utilizes time difference, so that towards estimated time point
Direction implement adjust.
For this purpose, by camshaft preferably directly after NW- controller starts or starts towards desired angle on target
Direction adjust.Parking area or the outer boundary bar of the parking spot or determination determining is passed through in the direction of described angle on target
The oil temperature of part such as explosive motor is defining.
Start in electromotor controller or start and the described angle on target between electromotor controller and NW- controller
（It is also referred to as specified regulation angle）After communicating first, can finally know and can be adjusted desired in the way of adjusting
Angle on target.
Run in order to ensure occurring without negative effect such as fault igniting or the notable sound or uneven electromotor, root
According to a viewpoint of the present invention, NW- controller is started with sending a state notifying.Described state notifying is for example applied to data
In bus such as CAN.Described state notifying includes at least one status information.
Described status information can be for example the inswept anglec of rotation of the motor with regard to camshaft adjuster
Or the notice of angular velocity of rotation.The anglec of rotation of described motor or rotary speed for example can be believed by the Hall element of motor
Breath is obtained.
Another feature of the present invention is related to communications reception between two controllers and with regard to the reliable starting control time
The inspection of aspect.In view of this respect suggestion, by means of electromotor controller, electromotor controller start to terminate after,
Read the state notifying of NW- controller and therefrom try to achieve regulation angle or for adjusting the credible scope of angle or being used for current
Adjust the regulation angle position of angle position.
In addition may need by means of the value tried to achieve or value scope be directed to undesirable negative effect such as fault light a fire or
Similar fault aspect implements verification.If undesirable effect can reliably be excluded, for example, pass through targetedly to spray
To import or to continue engine startup with igniting.
