Vehicle parking control device
First Claim
1. A vehicle parking control device comprising:
- a vehicle electronic control unit for controlling a vehicle, the vehicle electronic control unit being configured to;
specify a target position as a target at a time when the vehicle is stopped, the target position being an installation position of a power supplying pad for electric power supply by way of magnetism;
set a predetermined range that includes the target position, wherein the predetermined range is a range that is greater than a charging capable range within which a power supplying pad and a power receiving pad are capable of being magnetically coupled;
determine whether or not a reference position of the vehicle is positioned inside of the predetermined range, the reference position being a mounted position of the power receiving pad;
estimate an inclination state in a longitudinal direction of the vehicle;
estimate a state of charge of a battery; and
switch between creep torque characteristics of the vehicle, in response to determining that a predetermined condition that the reference position of the vehicle is positioned inside of the predetermined range and an estimated state of charge of the battery is less than a predetermined value is satisfied,wherein the creep torque characteristics are switched so as to increase a creep torque in response to an estimated vehicular inclination state of an upward slope and to decrease the creep torque in response to the estimated vehicular inclination state of a flat or downward slope.

Abstract
At a time that a parking operation is performed, a vehicle parking control device detects that a power receiving pad of an electric vehicle lies within a characteristics modifying range. Furthermore, the vehicle parking control device detects that other predetermined conditions are satisfied. In the case that the power receiving pad is positioned inside of the characteristics modifying range, and if all of the predetermined conditions have been satisfied, an acceleration-OFF-state movement characteristic of the vehicle, for example, a creep torque characteristic or a brake hydraulic pressure characteristic, is switched to an appropriate characteristic from a characteristic thereof at normal times.

-
a vehicle electronic control unit for controlling a vehicle, the vehicle electronic control unit being configured to; specify a target position as a target at a time when a vehicle is stopped, the target position being an installation position of a power supplying pad for electric power supply by way of magnetism; set a predetermined range that includes the target position, wherein the predetermined range is a range that is greater than a charging capable range within which a power supplying pad and a power receiving pad are capable of being magnetically coupled; determine whether or not a reference position of the vehicle is positioned inside of the predetermined range, the reference position being a mounted position of the power receiving pad; estimate an inclination state in a longitudinal direction of the vehicle; store a brake hydraulic pressure characteristic; and modify the brake hydraulic pressure characteristic when the reference position of the vehicle is positioned inside of the predetermined range, wherein a brake hydraulic pressure characteristic is modified so that a rate of rise of the brake hydraulic pressure decreases in response to an estimated vehicular inclination state of an upward slope and increases in response to estimated vehicular inclination state of a flat or downward slope.
