CPC B60W 30/06 (2013.01) [B60W 10/18 (2013.01); B60W 10/20 (2013.01); B60W 30/02 (2013.01); B60W 50/08 (2013.01); B60W 2554/20 (2020.02)] | 1 Claim |
1. A parking assist system for a vehicle including a powertrain, a brake device, and a steering device, the parking assist system comprising:
a control device configured to control the vehicle to execute an automatic moving process for autonomously moving the vehicle from a current position to a target position; and
an external environment sensor configured to detect an obstacle present around the vehicle,
wherein the powertrain includes a transmission,
the vehicle includes a shift device that can be operated by a driver to operate the transmission,
the brake device includes a parking brake device,
the control device is configured such that, in a case where a driving condition is satisfied when the control device stops the vehicle during movement to the target position in the automatic moving process and thereafter cancels the automatic moving process without permitting resumption of the movement of the vehicle, the control device switches a shift position of the shift device to a parking position and applies the parking brake device, and
the control device is configured to determine that the driving condition is satisfied when at least one of following conditions is satisfied: (i) the control device stopped the vehicle because the automatic moving process did not end even though a prescribed time period elapsed from a start of the automatic moving process, and (ii) the control device stopped the vehicle because a failure occurred in the parking assist system during execution of the automatic moving process,
wherein the control device is configured such that, in a case where a non-driving condition is satisfied when the control device stops the vehicle during the movement to the target position in the automatic moving process and thereafter cancels the automatic moving process without permitting resumption of the movement of the vehicle, the control device switches the shift position of the shift device to the parking position but does not apply the parking brake device regardless of whether a parking brake setting set beforehand by the driver is turned on,
the control device is configured such that, in a case where the non-driving condition is not satisfied when the control device stops the vehicle during the movement to the target position in the automatic moving process and thereafter cancels the automatic moving process without permitting resumption of the movement of the vehicle, the control device switches on/off the parking brake device depending on whether the parking brake setting is turned on, and
the control device is configured to determine that the non-driving condition is satisfied when at least one of following conditions is satisfied: (i) the control device stopped the vehicle according to an operation of the shift device by the driver; (ii) the driver operated the shift device during a period from when an event that necessitated stop of the vehicle occurred to when the vehicle was stopped; (iii) the shift position of the shift device is a neutral position at a time when the vehicle was stopped; (iv) the control device stopped the vehicle because the external environment sensor detected an obstacle that may collide with the vehicle, and the obstacle is not removed within a prescribed time period from detection of the obstacle or stop of the vehicle; (v) the vehicle is equipped with a vehicle stability assist system and the control device stopped the vehicle according to an operation of the vehicle stability assist system; and (vi) the parking assist system is temporarily inoperable.
