During thering is the travelling of vehicle 1 of above such structure, the speed of a motor vehicle in the time there is vehicle collisionSharply reduce, but sometimes because the sharply minimizing of this speed of a motor vehicle makes a MG20 rotation, thereby firstMG20 produces counter electromotive force.
Fig. 3 is that engine speed Ne, the MG show vehicle collision on nomogram time turnsThe figure of the situation of the variation of speed Nm1, the 2nd MG rotational speed N m2.
As mentioned above, engine speed Ne, a MG rotational speed N m1, the 2nd MG rotational speed N m2In nomogram, become the relation connected with straight line. , a MG rotational speed N m1 is turned by engineSpeed Ne and the 2nd MG rotational speed N m2 and determining. Due to the 2nd MG30 via decelerator 50 with driveDriving wheel 80 links, so the 2nd MG rotational speed N m2 is the value being directly proportional to the speed of a motor vehicle.
Advance by the power of engine 10 and the 2nd MG30 travel during (with reference to alignment L1)In the time there is vehicle collision, the speed of a motor vehicle i.e. the 2nd MG rotational speed N m2 sharply reduces. Now, existThe engine 10 of rotation wants to maintain same rotational speed according to the law of inertia. On the other hand, touch at vehicleWhile hitting, by ECU200, SMR71 being controlled is that off-state is cut off battery 70 from PCU60,Therefore, a MG20 cannot export torque. Therefore, as shown in alignment L2, in the time of vehicle collision,The one MG rotational speed N m1 is due to the sharply minimizing (row shown in Fig. 3 of the 2nd MG rotational speed N m2Exemplified with the speed of a motor vehicle, almost moment is reduced to 0 situation to line L2) and sharply increase, a MG20 passes throughBe arranged on the permanent magnet of a MG20 and produce large counter electromotive force. Therefore, in the time of vehicle collision,Wish to consume in advance the counter electromotive force being produced by a MG20.
But, in the time using discharge resistance 66 conducts to consume the equipment of this counter electromotive force, due to electric discharge electricityHinder 66 residual charges using extraction smmothing capacitor 64,65 as purposes, so its capacity is smaller,Off-capacity for consuming in advance the counter electromotive force that drives use and a MG20 capacious. SeparatelyOutward, in the time using not shown idle call motor (compressor etc.) conduct to consume the equipment of counter electromotive force,Because the rise of rotational speed at idle call motor is to consuming produced by a MG20 of the use of travelling anti-Can spend the considerable time before the rotating speed of electromotive force, so can not consume in advance by the of the use of travellingThe counter electromotive force that one MG20 produces. And then, also off-capacity likely in idle call motor.
Therefore, the ECU200 of the present embodiment makes EHC relay R 1, R2 close in the time of vehicle collisionIncompatible EHC140 is electrically connected with a MG20, thus by the large EHC140 of power consumptionConsume the counter electromotive force being produced by a MG20 in the time of vehicle collision. This point is the tool of the present inventionA bit of feature.
Fig. 4 is the functional block diagram of the ECU200 of the part relevant to control when the vehicle collision.ECU200 comprises collision determination portion 210, SMR cutting portion 220 and EHC Control portion 230.
To whether there is vehicle collision in the testing result of collision determination portion 210 based on crash sensor 2Judge, and result of determination is outputed to SMR cutting portion 220, EHC Control portion 230.
In the situation that being judged to be vehicle collision has occurred, SMR cutting portion 220 disconnects SMR71By disconnected to battery 70 and PCU60 TURP.
In the situation that being judged to be vehicle collision has occurred, EHC Control portion 230 is based on electric leakageDetector 150 is to having or not EHC electric leakage to judge. And, in the situation that there is no EHC electric leakage,EHC Control portion 230 makes EHC relay R 1, R2 closure by EHC140 and firstMG20 electrical connection.
Fig. 5 be while being illustrated in vehicle collision, make EHC relay R 1, R2 closure situation under supplyBe given to the mobile figure of the electric current of EHC140. As mentioned above, in the time of vehicle collision, a MG20Because the sharply minimizing of the 2nd MG rotational speed N m2 is rotated, thereby produce anti-electricity by a MG20Kinetic potential.
As shown in Figure 5, the electric current being produced by this counter electromotive force is supplied to by converter 62EHC140. Thus, can consume in advance produced by a MG20 anti-electronic by EHC140Gesture. Now, the electric current being produced by counter electromotive force flows via the diode of converter 62, therefore, andThe electric current that converter 62 is worked produced by counter electromotive force also can be at MG20 and an EHC140Between flow. Further, in the present embodiment, EHC140 is connected to converter 61 and converterBetween 62. Therefore, do not need converter 61 is worked yet. Therefore, in the present embodiment,Make to have cut off SMR71 in the time of vehicle collision, even or because the impact of vehicle collision makes converter61 and converter 62 be absorbed in inoperable state, also can consume by by ECU140The counter electromotive force that one MG20 produces.
Return to Fig. 4, EHC Control portion 230 makes EHC relay R 1, R2 closureAfter, to adding up from the EHC power consumption Pehc that monitors sensor 120, disappear at EHCThe aggregate-value of power consumption power Pehc has exceeded in the situation of predetermined feasible value, makes EHC relayR1, R2 disconnect making EHC140 and a MG20 non-electric-connecting. Thus, turn at a MGSpeed Nm1 consumes by EHC140 produced by a MG20 anti-before being reduced to a certain degreeElectromotive force, and make EHC140 consumed the electric power amount that exceedes feasible value by EHC140 afterNon-electric-connecting with a MG20, thus the overvoltage of EHC140 and overheated can be suppressed.
Fig. 6 is the flow chart that represents the treatment step of the ECU200 for realizing above-mentioned functions. This streamJourney figure repeatedly carries out with the predetermined cycle between the starting period of ECU200.
In step (following, step is economized to slightly " S ") 10, ECU200 is to having or not vehicle collisionJudge. In the situation that there is no vehicle collision, (in S10, being "No"), finishes this processing.
In the situation that there is vehicle collision (being "Yes" in S10), ECU200 cuts in S11Disconnected SMR71.
In S12, ECU200 is to having or not EHC electric leakage to judge. Exist EHC to leak electricityIn situation, (in S12, being "No"), finishes this processing.
In the situation that there is no EHC electric leakage (being yes in S12), ECU200 makes in S13EHC relay R 1, R2 closure. Thus, consume by first by EHC140 as described aboveThe counter electromotive force that MG20 produces.
In S14, ECU200 adds up EHC power consumption Pehc.
In S15, whether ECU200 has exceeded and has allowed the aggregate-value of EHC power consumption PehcValue is judged. Do not exceed feasible value at the aggregate-value of EHC power consumption Pehc (In S15, be "No"), process and return to S14, repeatedly EHC power consumption Pehc is added up.
Exceed feasible value at the aggregate-value of EHC power consumption Pehc and (in S15, be"Yes"), ECU200 makes EHC relay R 1, R2 disconnect in S16. Thus, can suppressThe overvoltage of EHC140 and overheated.
Above, in the vehicle 1 of the present embodiment, in the situation that having there is vehicle collision, ECU200Make EHC relay R 1, R2 closure by a MG20 with can consume jumbo electric powerEHC140(resistance) electrical connection. Thus, can consume in advance in vehicle collision by EHC140Time by the one MG20 produce counter electromotive force.
