Electric parking brake device
First Claim
1. A parking brake device for a road vehicle at least two of whose wheels on the same axle are steered wheels whose steering angle is imposed selectively on each of the steered wheels by a dedicated actuator, each actuator being controlled by a direction control unit which determines for each of the steered wheels a steering angle as a function of at least one signal delivered by a vehicle path control element, wherein the parking brake device comprises a parking brake control element which transmits a parking brake locking command to the control unit;
- said control unit being operative, upon receipt of a parking brake locking command, to transmit to the actuator for at least one steered wheel a steering command such that a displacement incompatibility is produced.

Abstract
An electric parking brake device for a vehicle at least two of whose wheels on the same axle are steered wheels whose steering angle is imposed selectively on each steered wheel by a dedicated electric actuator, each electric actuator being controlled by a direction control unit which determines a steering angle for each of the steered wheels as a function of at least one signal delivered by a vehicle path control element. A parking brake control unit delivers a parking brake locking command to the control unit, such that, upon receipt of a parking brake locking command, the control unit transmits antagonistic steering angle commands to the two wheels on the same axle.
