As it is shown in figure 1, the embodiment of the present invention includes:
nullA kind of motor-driven power steering control device，Including steering wheel 1、Rotation direction sensor 2(torque sensor or torque corner integrated transducer)、Turbine and worm decelerator 3、Steering column 4、Rack and pinion steering gear 5、Tire 6、ECU 15、Assist motor 13 and battery feed 7，Described steering wheel 1 is connected to the front end of steering column 4，Described rotation direction sensor 2 is arranged in steering column 4，Described turbine and worm decelerator 3 is arranged on steering column 4 and is positioned at the lower section of rotation direction sensor 2，The rear end of described steering column 4 is connected to rack and pinion steering gear 5 centre position，Described tire 6 is separately positioned on the two ends, left and right of rack and pinion steering gear 6，Described ECU 15 is connected with rotation direction sensor 2 and assist motor 13 respectively，Described assist motor 13 is connected to a side of turbine and worm decelerator 3，Described battery feed 7 is connected with ECU 15.

Generally speaking; owing to EPS belongs to vehicular high-power parts; in order to protect Vehicular accumulator cell; the startup of ECU 15 needs to meet some requirements; such as vehicle just must can carry out Power assisted control by ECU 15 in the start-up conditions; power torque, one of judgement signal that therefore whether engine rotational speed signal 9 can start as ECU 15 are provided.
As shown in Figure 2, ECU 15 includes the Torque Control ring 36 being sequentially connected with, coordinating control module 38, motor control module 33 and power driver module 34, described Torque Control ring 36 receives GES 8, engine rotational speed signal 9, torque and angular signal 11, output target current value 37, target current value 37 is carried out limiting control by described coordinating control module 38, export limited target current value 39, limited target current value 39 is as the input of motor control module 33, described motor control module 33 also receives the motor corner from assist motor 13 and the feedback of current signal 12, export 6 road pwm control signals 35 to power driver module 34, voltage 14 is controlled to assist motor 13 by described power driver module 34 output motor.
36 is the Torque Control ring of EPS, ECU receives GES 8, engine rotational speed signal 9, torque and angular signal 11, calculates target current value 37, including basic power-assisted target current, rotary transform tensor target current, damping controls target current and compensates current target value.38 is EPS coordinating control module, the function of this module is based on battery tension signal 30, environment (or ECU or assist motor) temperature signal 31 and other signals 32(can be steering wheel angle signals, can also be rack displacement signal or other signals) carry out target current value 37 limiting control, export limited target current value 39.Such as when detecting that battery tension signal 30 is too low, then target current value 37 is multiplied by a voltage coefficient value in 0 ~ 1 scope, thus obtains a little target current value of the original target current value of ratio, prevent from damaging because of battery overdischarge.Detect for another example when ambient temperature is too high, similarly, target current value 37 is multiplied by a voltage coefficient value in 0 ~ 1 scope, thus obtains a little target current value of the original target current value of ratio, it is achieved protection ECU and the purpose of motor.Limited target current value 39 is as the input of motor control module 33, and motor control module 33 is the electric current loop of EPS, it is achieved the tracking to target current of the motor actual current, thus exports desirably power torque.Following the tracks of target current in order to actual current is better achieved, motor control module 33 the most also receives the rotating speed from motor and the feedback of current signal 12.Motor control module 33 exports 6 road pwm control signals to power driver module 34, and power driver module 34 is H bridge or 3 phase inverter bridge, corresponds respectively to assist motor 13 for brush motor and brushless electric machine.Power driver module 34 output motor controls voltage 14 to assist motor 13.
ECU 15 judges the mode of operation of self according to vehicle body peripheral signal, and the condition conversion process of its different working modes is as shown in Figure 3.
In Fig. 3, circle 16,18,20,23,27 is respectively the OFF state of ECU 15, power-up initializing state, Run state, Fault state and lower electro-detection state.OFF state 16 is the cold state of ECU, neither receives extraneous signal, does not the most export control signal.Arrow line in Fig. 3 then represents the condition of conversion between different conditions.17 is ignition signal power-up conditions, i.e. IG ON.ECU detects that IG signal is high level, then move to power-up initializing state 18 from OFF state 16, completes self-inspection and the initialization of ECU, i.e. before ECU enters normal power-assisted, ECU and EPS is carried out one-time detection, it is ensured that system can normal power-assisted.State 18 is normal through rear, if be detected that there is engine speed conditions 19, then state is transferred to Run state 20, and Run state 20 is the kernel state of ECU, and the control function (power-assisted, Hui Zheng, damping etc.) of EPS is all to complete in this case.If electricity (i.e. IG off under ignition signal in state 18 running, condition 28), ECU enters lower electro-detection state 27, completes to close predrive, disconnection safety relay, Discharge electric capacity, renewal EEPROM, close the tasks such as power supply in lower electro-detection state 27.If state 18 running detects faulty existence (condition 24), then enter Fault state 23.In Run state 20 running, if meeting condition 22, being i.e. in operation and faulty generation being detected, fault is probably sensor fault, it is also possible to ECU internal fault, and system enters Fault state 23, in Fault state 23, ECU is respectively processed according to fault level.If meeting condition 21, i.e. engine misses in Run state 20 running, engine speed is zero, and system enters lower electro-detection state 27.When system is in Fault state 23, if be detected that engine speed is zero (condition 25), then enter lower electro-detection state 27.If be detected that electricity (i.e. IG off, condition 29) under ignition signal, then system is transferred to OFF state 16 by lower electro-detection state 27.
As it has been described above, generally ECU is transformed into lower electro-detection state 27 from Run state 20 is due to driver's switch-off, it is not required to provide EPS power-assisted.But being not excluded for following possibility during vehicle uses, vehicle is in normal transport condition and is in steering procedure, causes engine misses, i.e. engine rotational speed signal for a certain reason and is reduced to suddenly abnormal condition.If electro-detection state 27 from Run state 20 enters the most immediately, then power-assisted can suddenly disappear, and this operating mode easily causes security incident.
Propose a kind of time delay Power assisted control strategy for this present invention, to tackle this operating mode, improve the safety of EPS.Concrete grammar is as shown in Figure 4.

B, second condition judge, it is judged that engine rotational speed signal is the most faulty, if conditional judgment meets, and IG=OFF, then system continues power-assisted 5s, and is gradually reduced power-assisted value, enters back into EP (end of program)；If conditional judgment meets, and IG=ON, then system keeps continuing power-assisted；If condition is unsatisfactory for, then it is directly entered EP (end of program).
C, lasting power-assisted, continue to enter back into EP (end of program) after power-assisted completes.
Program, from the beginning of 40, is introduced into conditional judgment 41, it is judged that whether speed is more than V0, V0 is pre-set vehicle speed value, takes 5km/h, it is also possible to take other nonzero values in this example.If the Rule of judgment of 41 is unsatisfactory for, then enter EP (end of program), enter 46.Work as V > V0, when meeting Rule of judgment, program enters Rule of judgment 42, and engine rotational speed signal is the most faulty, if condition 42 is unsatisfactory for, program enters 46.If condition meets, and IG=ON, then system keeps continuing power-assisted.If condition meets, and IG=OFF, then the system continuation power-assisted 5s(persistent period can be changed as the case may be), power-assisted value is gradually reduced, and concrete effect is as shown in Figure 5.
In Fig. 5, coordinate axes 47 is target current value, coordinate axes 53 is the time, 48 is the target current value before the generation of engine rotational speed signal fault, 51 there is the moment for engine rotational speed signal fault, after 49 occur for engine rotational speed signal fault, the change that ignition signal is target current value during ON state detected, after 50 occur for engine rotational speed signal, the change of target current value when ignition signal is OFF state detected, now target current is gradually reduced from initial value, zero is reduced to during to 52 moment, in the present invention, 52 moment took 5s after generation engine rotational speed signal fault.
In sum, the motor-driven power steering control device of the present invention and time delay power assist control method thereof, there is simple in construction, save the advantage such as fuel oil, variable steering characteristic, consider a kind of extreme danger operating mode being likely to occur in normal driving cycle simultaneously, i.e. there is engine rotational speed signal fault during normal vehicle operation, under this operating mode, ECU is not directly to cut off power-assisted, and it is based on GES, the matching relationship of ignition signal and engine rotational speed signal carries out time delay Power assisted control, is effectively increased the safety of EPS.
