Abstract
Official abstract text for this publication.
A rotation of a right wheel ( 3 RR) and a rotation of a left wheel ( 3 RL) of a vehicle are locked respectively by independent parking lock mechanisms ( 6 ). Each parking lock mechanism ( 6 ) comprises a locking operation prevention mechanism ( 63 c, 63 d ) which mechanically prevents the locking operation of the parking lock mechanism ( 6 ) when a wheel rotation speed exceeds a predetermined parking lock prevention wheel rotation speed. The controller (CU, 10 ) is programmed to prevent the locking operation of the parking lock mechanisms ( 6 ) of the right and left wheels ( 3 RR, 3 RL) when a predetermined parking lock permitting condition based on wheel rotation speeds of the right wheel ( 3 RR) and the left wheel ( 3 RL) is not satisfied, thereby preventing a state in which one of the right and left wheels ( 3 RR, 3 RL) is prevented from rotating while the other is not prevented from rotating.
First claim
Opening claim text (preview).
The invention claimed is: 1. A parking lock device for a vehicle having a right wheel and a left wheel, comprising: a right parking lock mechanism which locks a rotation of the right wheel, the right parking lock mechanism comprising a locking operation prevention mechanism which mechanically prevents a locking operation of the right parking lock mechanism when a wheel rotation speed of the right wheel exceeds a predetermined parking lock prevention wheel rotation speed; a left…
