Description
Technical field
The present invention relates to the control system to the engine starter motor that the engine starter motor of the resistance possessed for suppressing electrical current controls, be particularly applicable to when preventing starting motor action moment break the control system of engine starter motor.
Background technique
Use starting motor when carrying out engine start, after starting the motor energising to starting motor, and then flow into the transition current being called as inrush current from battery, the voltage between terminals of battery declines to a great extent instantaneously.Due to this voltage drop, the electronic unit such as onboard navigation system or driven steering device that vehicle carries sometimes is caused to sink into the moment break of action halted state.
Particularly in recent years, in order to response environment and energy saving, under the rated condition of pressing signal temporary parking etc. at automobile, stop the fuel supply to motor, automatically suppress the demand of the idling system dallied to grow to even greater heights.In the vehicle being equipped with this idling system, when being restarted by the motor after starting motor carries out idle stop, compared with prior art, the time of movement of starting motor increases, therefore, when preventing starting motor action moment break countermeasure just become extremely important.In addition, due under the situation of vehicle action, starting motor likely carries out action, therefore, during starting motor action moment break Prevent countermeasures become extremely important.
The technology of pausing instantaneously as preventing this, possessing resistance, starting motor from a framework to the o of the auxiliary contact of the energising of resistance, opening and closing auxiliary contact that be used for the auxiliary selenoid switch that short circuit is arranged between the main contact of battery and starting motor is known (for example, referring to patent documentation 1).This starting motor is when motor energising starts, closed main contact, electric current after being limited via resistance is energized to motor, afterwards, during the counterelectromotive force formed producing enough rotation by motor, auxiliary selenoid switch is driven to be closed by auxiliary contact thus by resistance bypass (walking around), thus, make the full voltage of battery put on motor.
In the starting motor that patent documentation 1 is recorded, the auxiliary selenoid switch of opening and closing auxiliary contact carries out action under the state of the voltage drop of battery because flowing to the electric current of motor via resistance.Because of the deterioration etc. of battery, when the charging of the situation that the voltage drop of battery during motor energising is large or battery is insufficient, sufficient electric current can not be flow through in the field coil of auxiliary selenoid switch, therefore auxiliary contact can not be closed, consequently, become the state that motor current is continued by resistance to limit, therefore the starting time of motor is elongated.In addition, owing to flowing through the big current of drive motor in resistance for a long time, fusing or the part around that can produce resistance produce fire damage, thus lose the electrical path to motor, likely sink into the state of motor fail to start.
Therefore, in the vehicle being equipped with idling system, vehicle control system is set as, just confirming that the charge volume of battery is abundant, deterioration of battery situation, under starting motor can carry out the situation of engine start, allow the idle stop (for example, referring to patent documentation 2) of vehicle.

Embodiment
, use Fig. 1 ~ Fig. 4 below, the formation of the control system of the engine starter motor of one embodiment of the present invention and action are described.
First, the formation of Fig. 1 to the control system of the engine starter motor of present embodiment is used to be described.
Fig. 1 is the System's composition figure of the control system of the engine starter motor of one embodiment of the present invention.
Starting motor 1 comprises motor 2, main magnetic switch 3, small gear 4, speed change lever 5, main contact 7 are formed.Motor 2 produces the rotating force that engine start needs.The rotating force of motor 2 is passed to engine side gear ring 6 by small gear 4.Small gear 4 transports to gear ring 6 direction by speed change lever 5, engages with gear ring 6 to make it.Main contact 7 controls the energising to motor 2.Main magnetic switch 3 is built-in with main contact 7, controls the action of speed change lever 5.
In addition, in native system, except control circuit 8, battery 9, also possesses current confinement part 10.Current confinement part 10 possesses auxiliary selenoid switch 12, auxiliary contact 20 and resistance 30.Resistance 30 from battery 9 to the power-on circuit of motor 2 with main contact 7 arranged in series.Auxiliary contact 20 can switch to and make resistance 30 short circuit and from battery 9 directly to motor 2 alive circuit.The built-in auxiliary contact 20 of current confinement part 10, controls the opening and closing of auxiliary contact 20.When auxiliary contact 20 closes, not by resistance 30, the big current of battery 9 flows to motor 2.When auxiliary contact 20 disconnects, by resistance 30, confined electric current flows to motor 2 from battery 9.
Control gear 8 can be connected with the outside terminal 14 and 15 of main magnetic switch 3 and current confinement part 10, is controlled the opening and closing (disconnecting closed) of main contact 7 and auxiliary contact 20 by energising.
In the present embodiment, current confinement part 10 by built-in resistor 30 and the framework different from main magnetic switch 3 form, but resistance 30 also can be configured in main magnetic switch 3 or configure separately, and in addition, main magnetic switch 3 and current confinement part 10 also can be made up of same framework.
Then, use Fig. 2 ~ Fig. 4, the action of the control system of the engine starter motor of present embodiment is described.
Fig. 2 is the flow chart of the action of the control system of the engine starter motor representing one embodiment of the present invention.Fig. 3 and Fig. 4 is the time diagram of the action of the control system of the engine starter motor that one embodiment of the present invention is described.
In the control system of the engine starter motor of present embodiment, engine start request is divided into initial start-up request and restarts this two class of request to perform control.At this, so-called initial start-up request refers to the engine start request that the ignition switch operations from driver produces, and what is called restart request refer to the rated condition meeting the speed of a motor vehicle, charge condition of battery etc., after vehicle becomes idle stop state, according to idle stop canceling conditions such as brake release, the situation of automatically being piloted engine by the instruction carrying out self-control device.
In the step 110 of Fig. 2, control gear 8 judges that engine start request is initial start-up request or restarts request.Such as, monitoring the input signal from ignition switch, when there being the input signal from ignition switch, being judged to be initial start-up request.On the other hand, based on the situation of the start request from the signal beyond the input signal of ignition switch, be judged to restart request, or detection idle stop enabling signal, there is the situation of start request to be judged to restart request afterwards.
When control gear 8 is judged as YES and restarts request, enter the step 120 of the flow chart of Fig. 2.The open and-shut mode (Fig. 3 (B)) of open and-shut mode (Fig. 3 (A)) after Fig. 3 represents the control carried out from the step 120 of Fig. 2 to step 180, main contact 7, auxiliary contact 20, the voltage (Fig. 3 (C)) of battery 9 and flow through the electric current (Fig. 3 (D)) of motor 2.
In the step 120, the outside terminal 14 of control gear 8 to main magnetic switch 3 is energized thus pushes small gear 4 and make it engage with gear ring 6, then start to be energized to motor 2 by closed main contact 7, but because the electrical current to motor 2 is limited by resistance 30, motor 2, with low speed rotation, starts the crank rotation of motor, the generation of the transition current after starting therefore, it is possible to suppression is energized, reduce the voltage drop of battery 9, keep voltage between terminals V1 higher.
Then, judge in step 130 whether the rated condition of resistance 30 short circuit is set up.When the condition of resistance 30 short circuit is set up, enter step 140, the outside terminal 15 of control gear 8 pairs of current confinement part 10 is energized, and auxiliary contact 20 closes.Thus, formed by resistance 30 short circuit from battery 9 to motor 2 alive circuit, motor 2 is to start at a high speed the crank rotation (cranking, crank) of motor.When being switched to the power-on circuit making resistance 30 short circuit, motor 2 becomes by the energising in step 120 with the state of low speed rotation, the voltage drop of the battery 9 when power-on circuit switches can be reduced by the counterelectromotive force (the inverse Electricity of rising pressure) according to rotating speed, keep voltage between terminals V2 higher.
As the rated condition in step 130, such as, the cell voltage shown in watch circle 3 (C), when cell voltage becomes more than assigned voltage, is judged to be that rated condition is set up.When using the battery of 12V, as assigned voltage, such as, be set as 10V.In addition, as other rated condition, monitoring the time process after main contact conducting, when have passed through the stipulated time, being judged to be that rated condition is set up.About the stipulated time, different according to the size etc. of the air displacement of motor of being started by starting motor 1, the output of starting motor 1, but such as, set the time of about 30ms ~ 100ms.At this, object reduces the voltage drop of battery 9, keeps voltage between terminals V2 higher, so from such a viewpoint, rated condition preferably monitors cell voltage.But because the time carrying out monitoring is about 30ms ~ 100ms, therefore the supervision of cell voltage such as needs every 10ms just to carry out once.In common engine control, cell voltage changes not significantly, therefore carries out monitoring every the long time, so need not carry out the supervision of every 10ms such short time.Therefore, in order to engine start, every 10ms monitors cell voltage, control gear 8 is born larger.So, in order to alleviate this burden, as the second mode of execution, monitor that the mode of the time after main contact 7 conducting is not only easy but also suitable mode.
After the process of step 140, in step 170, judge that the starting of motor completes condition and whether sets up.When the condition of starting has been set up, enter step 180, stop the energising of main magnetic switch 3 and auxiliary selenoid switch 10, in step 190, terminate engine start and control.
In addition, the starting as motor completes condition, monitors engine speed (rotation number), when engine speed reaches close to no-load speed, can be judged to be that engine start completes.
Carry out motor as mentioned above when restarting, to suppress voltage drop during action, keep the higher mode of the voltage between terminals of battery 9 to implement to control, can prevent vehicle electronics parts moment break generation.
On the other hand, in step 110, when control gear 8 is judged to be initial start-up request, step 150 is entered.Fig. 4 represents when having carried out the control from step 150 to step 80, the voltage of the open and-shut mode of the open and-shut mode of main contact 7 (Fig. 4 (A)), auxiliary contact 20 (Fig. 4 (B)), battery 9 (Fig. 4 (C)) and flow through the electric current (Fig. 4 (D)) of motor 2.
During the initial start-up of motor, in step 150, control gear 8 is energized to the outside terminal 15 of auxiliary selenoid switch 10, closed auxiliary contact 20, will switch to the circuit of resistance 30 short circuit from battery 9 to the power-on circuit of motor 2.
Then, in a step 160, by being energized to the outside terminal 14 of main magnetic switch 3, utilizing speed change lever 5 that small gear 4 is moved, making it engage with gear ring 6.Then, main contact 7 closes, because energising motor 2 starts to rotate.Now, switch to the circuit that resistance 30 has been shorted by auxiliary contact 20, therefore the full voltage of battery 9 is by applied to motor 2, and motor 2 is to start at a high speed the crank rotation of motor.
In step 170, judge that the starting of motor completes condition and whether sets up.When condition of having started is set up, enter step 180, stop the energising of main magnetic switch 3 and auxiliary selenoid switch 10, terminate engine start in step 190 and control.
In the present embodiment, during motor initial start-up, first avoid under the state of the energising of resistance 30 being closed auxiliary contact 20 by current confinement part 10, make the action of main magnetic switch 3 and closed main contact 7, drive the motor 2 of starting motor 1.Therefore, the state of the voltage drop of the battery 9 when motor 2 is energized, does not need to make current confinement part 10 action.Therefore, even if the electric discharge becoming state that battery 9 deteriorates or cause because of long-standing placement etc., under the hypodynamic state of electricity of driving current limiting unit 10, resistance 30 also can not flow continuously through electric current, can prevent from making motor sink into the situation of the state of fail to start because of the fusing of resistance 30 or the fire damage of surrounding components.In addition, be in halted state at vehicle, when driver sends the initial start-up of the motor of start request, prevent the significance of moment break little, therefore can by from energising time the full voltage of battery 9 is put on motor 2, realize engine start rapidly.
As described above, according to the present embodiment, when motor initial start-up, do not need to make current confinement part 10 carry out action under the state of the voltage drop of the battery 9 when motor is energized.Therefore, even if the electric discharge becoming state that battery 9 deteriorates or cause because of long-standing placement etc., thus the hypodynamic state of the electricity of driving current limiting unit 10, resistance 30 also can not flow continuously through electric current, can prevent from making motor sink into the situation of the state of fail to start because of the fusing of resistance 30 or the fire damage of surrounding components.
In addition, halted state is at vehicle, when driver sends the initial start-up of the motor of start request, prevent the significance of moment break little, therefore can by from being energized time the full voltage of battery 9 put on motor 2 and realize engine start rapidly.
Then, use Fig. 5 ~ Fig. 8, the formation of the control system of the engine starter motor of another embodiment of the present invention and action are described.
First, use Fig. 5, the formation of the control system of the engine starter motor of present embodiment is described.
Fig. 5 is the System's composition figure of the control system of the engine starter motor of another embodiment of the present invention.
In the starting motor 1 of the present embodiment, current confinement part 10A has resistance 30, and this resistance 30 is configuring from battery 9 in parallel with main contact 7 power-on circuit of motor 2.
Current confinement part 10A comprises auxiliary selenoid switch 12, auxiliary contact 20 and resistance 30.Auxiliary contact 20 and resistance 30 arranged in series.When closed auxiliary contact 20, formed by resistance 30 from battery 9 to motor 2 alive circuit.Consequently, in motor 2, flow through the electric current limited by resistance 30.When closed main contact 7, formed and from battery 9 to motor 2 alive circuit, can not make to flow through big current in motor 2 by resistance 30.
In addition, in the present embodiment, same with the first mode of execution, current confinement part 10A also by built-in resistor 30 and the framework different from main magnetic switch 3 form, but be not limited to this formation, resistance 30 also can be configured in main magnetic switch 3 or configure separately, and in addition, main magnetic switch 3 and current confinement part 10 also can be made up of same framework.
Then, use Fig. 6 ~ Fig. 8, the action of the control system of the engine starter motor of present embodiment is described.
Fig. 6 is the flow chart of the action of the control system of the engine starter motor representing another embodiment of the present invention.Fig. 7 and Fig. 8 is the time diagram of the action of the control system of the engine starter motor that another embodiment of the present invention is described.
In the step 210 of Fig. 6, control gear 8 judges that engine start request restarts request or initial start-up request.When being judged as restarting request, enter step 220.The open and-shut mode (Fig. 7 (B)) of open and-shut mode (Fig. 7 (A)) when Fig. 7 represents the control carried out when the restarting of the present embodiment from step 220 to step 280, main contact 7, auxiliary contact 20, the voltage (Fig. 7 (C)) of battery 9, flow through the electric current (Fig. 7 (D)) of motor 2.
In a step 220, control gear 8 closes auxiliary contact 20, and the electric current utilizing resistance 30 to limit is energized from battery 9 to motor 2.
Then, in step 230, judge whether the rated condition of carrying out alive circuit switching to bypass to ground 30 pairs of motors 2 is set up.When the switching condition of circuit is set up, enter step 240, control gear 8 makes the action of main magnetic switch 3 and closed main contact 7, simultaneously or immediately, stops the energising to current confinement part 10, and auxiliary contact 20 is open.Thus, switch to bypass to ground 30 to carry out alive circuit to motor 2, the full voltage of battery 9 is put on motor 2.
Now, the voltage of battery 9 and flow through the change of electric current and the effect thereof of motor 2, with the first mode of execution to restart action identical.
On the other hand, in step 210, when control gear 8 is judged to be initial start-up request, step 260 is entered.Fig. 8 represent the present embodiment carry out initial start-up time the control from step 260 to step 280 time, the voltage (Fig. 8 (C)) of the open and-shut mode (Fig. 8 (B)) of the open and-shut mode (Fig. 8 (A)) of main contact 7, auxiliary contact 20, battery 9, flow through the electric current (Fig. 8 (D)) of motor 2.
In step 260, control gear 8 closes main contact 7, the full voltage of battery 9 is put on motor 2 and makes engine start.Now, the voltage of battery 9 and flow through the change of electric current of motor 2 and the effect based on the control of the present embodiment, identical with the initial start-up action of the mode of execution of the 1st.
As described above, according to the present embodiment, in motor initial start-up, under the state of the voltage drop of the battery 9 when motor is energized, do not need to make main magnetic switch 3 or auxiliary selenoid switch 10A action.Therefore, even if the electric discharge becoming state that battery 9 deteriorates or cause because of long-standing placement etc., thus drive the hypodynamic state of electricity of magnetic switch, resistance 30 also can not flow continuously through electric current, can prevent from making motor sink into the situation of the state of fail to start because of the fusing of resistance or the fire damage of surrounding components.
In addition, be in halted state at vehicle, when driver sends the initial start-up of the motor of start request, prevent the significance of moment break little, therefore can by from energising time the full voltage of battery 9 is put on motor 2, realize engine start rapidly.
In addition, when the mode of execution shown in the mode of execution shown in Fig. 1 and Fig. 5 is compared, there is following difference.Current confinement part 10A shown in Fig. 5 is configuring from battery 9 in parallel with main contact 7 power-on circuit of motor 2.Therefore, such as, in resistance 30, long-time stream flows through big current, when auxiliary contact 20 damages because of heating, also can carry out the starting of motor by being closed by main contact 7.On the other hand, in the embodiment of figure 1, when if flow through big current for a long time in resistance 30, resistance 30 blows, auxiliary contact 20 damages, even if by closed for main contact 7 starting can not carrying out motor.On the other hand, in the embodiment of figure 1, current confinement part 10 from battery 9 to the power-on circuit of motor 2 with main contact 7 arranged in series.Therefore, will not have the situation of current confinement part 10 and have the situation of current confinement part 10 to compare, the quantity of the connector of starting motor 1 be identical, utilization of the formation of existing starting motor 1 can being kept intact, thus can reduce cost.On the other hand, in the formation of Fig. 5, needing an additional connector for carrying out inputting from the electric current of current confinement part 10A, can not keep intact and utilize the formation of existing starting motor 1.
Then, use Fig. 9, the variation of the controlling method in the control system of the engine starter motor of the embodiments of the present invention is described.In addition, the formation of the control system of the engine starter motor of present embodiment and the formation shown in Fig. 1 are identical.
Fig. 9 is the flow chart of the action of the variation of the control system of the engine starter motor representing the embodiments of the present invention.In the example of Fig. 9, for the flow chart shown in Fig. 2, add step 300.
In this example, following steps are added, namely, use the SOC (State Of Charge) of the ratio of battery capacity when representing full charge relative to battery 9 of present charge volume, in the control midway that motor is restarted, under judging the state that the SOC of battery 9 has driven at the motor 2 of starting motor 1, be whether for making magnetic switch 3 or 10 carry out the above step of the sufficient value of action, the circuit of this magnetic switch 3 or 10 for being switched to resistance 30 short circuit.
Specifically, the step of the SOC judging battery 9 is increased.In step 300, control gear 8 drives at the motor 2 of starting motor 1 and under the state of voltage drop, judges whether the SOC of battery 9 is as making current confinement part 10 carry out more than the sufficient value of action.When being judged to be the SOC deficiency of battery 9, enter step 140, carry out and control same during initial start-up shown in the first mode of execution.
In addition, be namely worth fully as decision condition, such as, can be set as that SOC is the situation of 70%.
In addition, above explanation is the variation of the mode of execution to Fig. 2, but for the flow chart shown in Fig. 6, by adding the step 300 of Fig. 9 after step 210, can control equally.
According to above present embodiment, the power consumption because of the use of vehicle electronics parts etc. in idle stop can be prevented, and the situation of restarting of motor can not be carried out.
