Parking auxiliary device

Abstract

The invention provides a parking auxiliary device (10) which has a parking auxiliary ECU (18). The parking auxiliary ECU (18) sets a targeted parking position (P1) of a vehicle (12), and exerts parking auxiliary control to guide the vehicle (12) to the targeted parking position (P1). The parking auxiliary ECU (18), based on the action of a parking brake of the vehicle which serves as a mechanical obstacle factor, prohibits the guiding of the vehicle (12), so that the parking auxiliary control is not executed. In this way, practicability is improved, and a phenomenon that wheels are dragged due to the parking brake action is prevented.

Description

technical field

[0001] The invention relates to a parking assistance device for assisting parking of a vehicle. Background technique

[0002] In order to assist the parking of the vehicle, a parking assistance device for guiding the vehicle to park the vehicle to a parking position is disclosed in the prior art. For example, Japanese Patent Laid-Open Publication No. Hei 10-264839 discloses an automatic parking device (parking assist device), which estimates the current position of the vehicle based on the wheel speed and the yaw rate, and compares the current position of the vehicle with the current position. The steering amount is corrected based on the offset from the target trajectory to guide the vehicle to the parking position.

[0003] In addition, for example, Japanese Patent Laid-Open Publication No. 2011-039600 discloses a parking assist device capable of automatically detecting a target parking position (which means a candidate for the final target parking positio...
