no. 1 Embodiment approach

[0039] [First Embodiment: First Configuration Example]

[0040] The parking assist device 10 according to the first configuration example of the first embodiment has an automatic steering function for automatically steering the steering wheel 14 of the vehicle 12 during a parking operation. In this automatic steering function, the parking assist device 10 guides the driver to operate the shift lever 16, the accelerator pedal (not shown), and the brake pedal (not shown), and the vehicle 12 is moved forward by the operator's operation. And back, braking, etc. Of course, the parking assist device 10 may also perform automatic steering, and automatically drive and brake the vehicle 12 .

[0041] The parking assist device 10 has a parking assist electronic control unit (hereinafter referred to as a parking assist ECU 18 ) as a control unit that performs parking assist control. The parking assist ECU 18 may be constituted by a computer having an input / output unit 20 , a computing ...

no. 2 Embodiment approach

[0130] Next, the parking assist device 112 according to the second embodiment of the present invention will be described. Figure 7 The shown parking assist device 112 is the same as the parking assist device 10 according to the first embodiment, and assists parking of the vehicle 110 by performing automatic steering. That is, the parking assist device 112 automatically operates the steering wheel 116 , and the driver operates an accelerator pedal, a brake pedal (both not shown), and a shift lever 138 . In addition to automatically operating the steering wheel 168, the parking assist device 112 can also automatically operate the accelerator pedal and brake pedal (driving and braking of the vehicle 110) and the gear lever 138 (switching between forward and reverse of the vehicle 110) .

[0131] The parking assist device 112 includes a sensor group 114 , a navigation device 116 , a parking assist ECU 118 , and an EPS system 120 . The sensor group 114 detects various detection v...

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...
