After locking bar 30 moved to non-locked position, the movable contact of non-locking switch 42 was pushed by the contact disk 30a of locking bar 30, and non-locking switch 42 carries out ON action (switch closure).Respond the ON of non-locking switch 42, the signal (high level signal) that the extension of expression locking bar 30 and steering shaft 20 closes the unlock state that has been disengaged is imported among the steering locking ECU40 by non-locking switch 42.In addition, be accompanied by the releasing of pushing to movable contact, non-locking switch 42 has the instantaneous corresponding function that returns to " switch opens " from " switch closure ".
Steering locking ECU40 is the cpu package with memory device 40a and not shown CPU, ROM, RAM, time meter etc.As shown in Figure 2, memory device 40a stores shortest time chart M1～MN that the ambient temperature T corresponding to motor 10 is set.In each shortest time chart, storing the benchmark shortest time X of the intermediateness (back detailed description) that is associated with the auxiliary voltage V of motor 10.Shortest time chart M1 reference be that the ambient temperature T of motor 10 is the situation in " T1≤T≤T2 " scope, shortest time chart M2 reference be that the ambient temperature T of motor 10 is the situation in " T2≤T≤T3 " scope, shortest time chart MN reference be that the ambient temperature T of motor 10 is the situation in " T (N-1)≤T≤TN " scope.
With Fig. 3 (a)～(c) explanation intermediateness.
Intermediateness be meant locking bar 30 by lock-out state in the unlock state transition process and by the state of unlock state in the lock-out state transition process.
That is, shown in Fig. 3 (a), under lock-out state, key lock switch 41 is in the locking bar 30 of latched position and opens (being in the ON action), but not key lock switch 42 is in the OFF action.Under lock-out state, motor 10 is inverted to drive and makes locking bar 30 after the arrow B direction moves, shown in Fig. 3 (b), the contact disk 30a of locking bar 30 is disengaged the pushing of movable contact of key lock switch 41, key lock switch 41 is transformed into the OFF action from the ON action, but not key lock switch 42 still remains on the OFF action identical with lock-out state.
Be transformed into OFF action back at key lock switch 41 like this and continue reverse 10, shown in Fig. 3 (c), the movable contact of non-locking switch 42 is pushed by the contact disk 30a of locking bar 30, make non-locking switch 42 be transformed into the ON action, and key lock switch 41 still remain on the OFF action identical with Fig. 3 (b) from the OFF action.
So, from the lock-out state shown in Fig. 3 (a) to the unlock state transforming process shown in Fig. 3 (c) and conversely from the unlock state shown in Fig. 3 (c) to the lock-out state transforming process shown in Fig. 3 (a), have key lock switch 41 and non-locking switch 42 all to be in the state (Fig. 3 (b)) of OFF action.The state that these key lock switches 41 and non-locking switch 42 all are in the OFF action just is called intermediateness.
Corresponding to the benchmark shortest time X of the intermediateness of the auxiliary voltage V of the ambient temperature T of motor 10 and motor 10 at design phase just by in advance good.Be stored among the memory device 40a by good benchmark shortest time X.
Under the situation that does not have foreign matter to exist between locking bar 30 and the non-locking switch 42 (key lock switch 41), be converted to the process of unlock state (lock-out state) from lock-out state (unlock state), the elapsed time of intermediateness is more than or equal to benchmark shortest time X.And under the situation that has foreign matter to exist between locking bar 30 and the non-locking switch 42 (key lock switch 41), because non-locking switch 42 (key lock switch 41) is pressed into the ON action by foreign matter, so the elapsed time of its middle state is just less than benchmark shortest time X.
According to above these situations, the benchmark shortest time X of the intermediateness that present embodiment will be measured in advance when not having foreign matter to exist is stored among the memory device 40a, and steering locking ECU40 compares the elapsed time of the intermediateness of reality with benchmark shortest time X.And, the non-locking control that is converted to unlock state (lock-out state) from lock-out state (unlock state) (locking control) process, steering locking ECU40 is condition with the elapsed time of the intermediateness of reality more than or equal to benchmark shortest time X, discerns (judgement) and is in unlock state (lock-out state).On the other hand, steering locking ECU40 is under the situation of the elapsed time of the intermediateness of reality less than benchmark shortest time X, owing to might between locking bar 30 and non-locking switch 42 (key lock switch 41), have foreign matter to exist, so nonrecognition is unlock state (lock-out state).
On steering locking ECU40, electrically connecting display part 45 (notifying device).Display part 45 demonstrates the information that might have foreign matter between locking bar 30 and non-locking switch 42 (key lock switch 41) according to the instruction of steering locking ECU40.
