Title: Park lock device of automatic transmission
Inventor: KANEHISA TAKANORI
IPC: B60W10/18
Filed: 1999-11-25
Abstract: PROBLEM TO BE SOLVED: To shift to the park lock state in the procedure without causing a large load on a park lock mechanism even in case of P-range shifting during running. SOLUTION: The steps 21 and 25 check whether the vehicle speed VSP is below a preset vehicle speed VSP1 for stopping determination, between the VSP1 and a second preset vehicle speed VSP2 higher than the VSP1, or equal to or higher than the second preset vehicle speed VSP2. In the case of VSP>=VSP2, the transition to the park lock state is inhibited in the step 22. In the case of VSP1<=VSP<VSP2, when P range select operation is detected in the step 23, an automatic brake is operated to decelerate a vehicle in the step 26, and when VSP<VSP1 is attained by the deceleration, the transition to the park lock state is executed in the step 27. Accordingly, the kinetic energy of the vehicle is absorbed by the automatic brake until the VSP is lowered below the VSP1.  The part lock mechanism does not share the energy in this period, so it is sufficient that the part lock mechanism fulfils only a function of keeping the stop state not to move the stopping vehicle.

Therefore, a magnetic field having strength 1.15 times as much as that of the magnetic field sensed when the inclined angle of the magneto-resistance element from the normal of the magnetic medium is 0 deg. can be sensed by the element.
