Title:
PARKING CONTROL SYSTEM FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2007/122851
Kind Code:
A1
Abstract:
A parking control system for a vehicle, where, when a shift range of an automatic transmission
is changed to a parking range, the system early and reliably applies sufficient
braking force to a parking brake and prevents the user from forgetting to apply
the parking brake. The parking control system for a vehicle has a shift-by-wire device
(26), an electric parking brake device (50), and an automatic transmission ECU
(60). The shift-by-wire device (26) is automatically driven based on an electrical range
position signal corresponding to a shift range of the automatic transmission (20),
thereby changing over the shift range of the automatic transmission (20), and
changes over a parking mechanism (27), installed in the automatic transmission (20),
between an engaged state and a disengaged state. The electric parking brake device
(50) is automatically driven by the range position signal to change over the parking
brake (53) of the vehicle between a braked state and a brake release state. The
automatic transmission ECU (60) drives the shift-by-wire device (26) and the
electric parking brake device (50) based on the relationship between the range
position signal and the parking range of the vehicle.
