It is to be the microprocessor at center with CPU 72 that hybrid type electronic control unit 70 is configured, and also comprises except that CPU 72: the ROM 74 of storage processing program, the RAM76 of temporary storaging data, not shown input/output port and COM1.By input port to hybrid type electronic control unit 70 input from the accelerator open degree Acc of the fire signal of ignition switch 80, the accelerator pedal position sensor 84 that detects from the gear SP of the gear position sensor 82 of the operating position that detects speed change lever 81, from the amount of jamming on, from the brake pedal position BP of the brake pedal position sensor 86 of the amount of jamming on that detects brake petal 85, from the vehicle velocity V of vehicle speed sensor 88 etc. to gas pedal 83.As mentioned above, hybrid type electronic control unit 70 is connected with Engine ECU 24, motor ECU 40, battery ECU 52, break ECU 66 by COM1, thereby carries out the exchange of various control signals or data with Engine ECU 24, motor ECU 40, battery ECU 52, break ECU 66.
So the embodiment's who constitutes hybrid vehicle 20 should be to the required torque as the gear ring axle 32a output of live axle based on the driver the corresponding accelerator open degree Acc of the amount of jamming on of gas pedal 83 and vehicle velocity V being calculated, and motor 22 is turned round control with output and the corresponding required drive of this required torque with motor M G1, MG2, MG3.As motor 22 and motor M G1, MG2, the running control of MG3, has torque conversion drive mode, charge-discharge drive mode, motor rotation pattern etc., wherein said torque conversion drive mode is meant, motor 22 is turned round control so that from the motor 22 outputs power suitable with required drive, and to motor M G1, motor M G2, motor M G3 carries out drive controlling so that all from the power of motor 22 output by power distribution assembly mechanism 30 and motor M G1, some among motor M G2 and the motor M G3 or two carry out torque transfer and export to gear ring axle 32a; Described charge-discharge drive mode is meant, motor 22 is controlled so that discharge and recharge the suitable power of required electric power sum from motor 22 outputs and required drive and battery 50, and motor M G1, motor M G2, motor M G3 carried out drive controlling, so that carry out torque transfer from the whole of the power of motor 22 output or its are a part of by some power distribution assembly mechanism 30 and motor M G1, motor M G2 and the motor M G3 or two, and export to gear ring axle 32a along with discharging and recharging of battery 50 thereupon; Described motor rotation pattern is meant the control of turning round, with the running of shutting engine down 22 and some from motor M G2 and motor M G3 or two to the gear ring axle 32a output power suitable with required drive.
Then, to the action of the hybrid vehicle among the embodiment of formation like this 20, particularly the action when the ato unit 22 describes when stopping.Fig. 3 starts the flow chart of an example handling routine when being the performed parking of expression embodiment's the hybrid type electronic control unit 70 of hybrid vehicle 20.When preset vehicle speed Vref that vehicle speed sensor 88 detected vehicle velocity V deficiencies are regarded as stopping, when request ato unit 22, carry out this routine.
After when carrying out parking, starting the processing routine, the CPU 72 of hybrid type electronic control unit 70 at first imports and controls required data (step S100), for example from the brake pedal position BP of brake pedal position sensor 86 or revolution Ne, motor M G2, each rotational position θ m2 of MG3, the motor temperature Tm of θ m3, motor M G2, the phase inverter temperature T inv of phase inverter 42 etc. of motor 22.Here, the revolution Ne of motor 22 is that basis is calculated by the detected rotational position of crankshaft position sensor, and import from Engine ECU 24 by communication.In addition, rotational position θ m2, the θ m3 of motor M G2, MG3 are detected by rotational position sensor 45,46, and import from motor ECU 40 by communication.Motor temperature Tm or phase inverter temperature T inv are detected by temperature transducer 47,48, and import from motor ECU 40 by communication.
So after the input data, whether the brake pedal position BP that judges input not enough predetermined value BPref (step S110).After stepping on brake petal 85, break ECU 66 is according to carrying out drive controlling from the control command of hybrid type electronic control unit 70 to brake actuator 64, so that act on from hydraulic brake 60a, 60b, 62a, 62b with the corresponding braking force of brake pedal position BP.Predetermined value BPref is redefined for by hydraulic brake 60a, 60b, 62a, 62b and makes the gear ring axle 32a as live axle lock necessary brake pedal position.Therefore, to the whether judgement of not enough predetermined value BPref of brake pedal position BP, the judgement whether gear ring axle 32a is fully locked by hydraulic brake 60a, 60b, 62a, 62b exactly.
If determine the not enough predetermined value BPref of brake pedal position BP, judge that then gear ring axle 32a does not have locking locked or gear ring axle 32a insufficient in hydraulic brake 60a, 60b, 62a, 62b, and compare motor temperature Tm and predetermined temperature Tmref (step S120), compare phase inverter temperature T inv and predetermined temperature Tiref (step S130).Here, predetermined temperature Tmref or predetermined temperature Tiref be used for determining can with motor M G2 separately locking be to determine as the temperature range gear ring axle 32a of live axle, motor M G2 or phase inverter 42 by the performance of motor M G2 or the performance of phase inverter 42 etc.
If judge not enough predetermined temperature Tmref of motor temperature Tm and the not enough predetermined temperature Tiref of phase inverter temperature T inv, then minimum position is moved in the rotation of motor M G2 and be made as locked position (step S150) according to the rotational position θ m2 that imports, and lock to motor ECU 40 indication motors, so that in three-phase coil with on the corresponding two-phase of locked position that sets, apply direct current (d.c.), thereby lock out motor MG2 (step S160).The state of motor-locking has been shown among Fig. 4.As shown in the figure, if on U phase, V phase, the W two-phase in mutually, apply direct current (d.c.), then on stator, form the fixed magnetic field (solid arrow in reference to figure) that synthesizes gained by the magnetic field that on the two-phase that has applied direct current (d.c.), forms respectively (dotted arrow in reference to figure), thereby thereby the rotor that is pasted with permanent magnet attracted locked by this fixed magnetic field.All have six owing to be formed on the direction of the fixed magnetic field on the stator by the combination of the conducting shutoff of transistor T 1～T6, thereby locked position also is and six corresponding six positions of fixed magnetic field.Therefore, by setting in these six locked positions, can when lock out motor MG2, make the rotation of motor M G2 move minimum, thereby the displacement distance of vehicle can be suppressed to inferior limit near the locked position of rotational position θ m2.In the present embodiment, the following setting of locked position:, that is: by obtaining the relation between rotational position θ m2 and the locked position and storing in advance among the ROM 74, after obtaining rotational position θ m2, derive corresponding locked position from mapping as mapping.
On the other hand, when judging motor temperature Tm is more than the predetermined temperature Tmref, or to judge phase inverter temperature T inv be that predetermined temperature Tiref is when above, according to the rotational position θ m3 that imports minimum position is moved in the rotation of motor M G3 and be made as locked position (step S140), and the position of minimum is moved in the rotation of motor M G2 according to the rotational position θ m2 that imports is made as locked position (step S150), lock to motor ECU 40 indication motors, so that in the three-phase coil separately of motor M G2 and motor M G3 with on the corresponding two-phase of setting of each locked position, apply direct current (d.c.) respectively, thereby lock out motor MG2 and motor M G3 (step S160).Thus, even be in the condition of high temperature and can't be with motor M G2 when locking is as the gear ring axle 32a of live axle separately when motor M G2 or phase inverter 42, also can utilize motor M G2 and motor M G3 both sides to lock gear ring axle 32a reliably.Narrated the locking of motor M G2 above.In addition, the locking of motor M G3 be by with the locking phase of motor M G2 with processing carry out, thereby save explanation to the locking of motor M G3.
So, after by motor M G2 or motor M G3 locking gear ring axle 32a, will be made as the detent torque Tcr that motor 22 starts required torque should be from the torque instruction Tm1 of motor M G1 output
