20 Claims

1. An auto hold control apparatus comprising:

a driver including at least one driving device for driving a vehicle;

a memory configured to store at least one instruction therein; and

a controller operatively connected to the driver and the memory,

wherein the auto hold control apparatus is configured to, when the at least one instruction is executed by the controller:

obtain a driving signal for releasing an auto hold of the vehicle, through the driver;

generate driving power through the driver, based on the obtained driving signal;

determine a movement standard deviation of an acceleration generated by the driving power from a first time point to a second time point;

generate at least one learning amount related to at least one of the generated driving power, a generated driving power inclination, a driving power generation time point, or a combination thereof, based on a magnitude of the movement standard deviation, when the movement standard deviation is a threshold value or more than the threshold value;

generate a predicted learning value by adding the at least one learning amount to a learning value which is stored in the memory in advance; and

store the predicted learning value in the memory as a final learning value when the predicted learning value satisfies a predetermined condition.

11. An auto hold control method comprising:

obtaining, by a controller, a driving signal for releasing an auto hold of a vehicle through a driver;

generating, by the controller, driving power through the driver, based on the driving signal;

determining, by the controller, a movement standard deviation of an acceleration generated by the driving power from a first time point to a second time point;

generating, by the controller, at least one learning amount related to at least one of the generated driving power, a generated driving power inclination, a driving power generation time point, or a combination thereof, based on a magnitude of the movement standard deviation, when the movement standard deviation is a threshold value or more than the threshold value;

generating, by the controller, a predicted learning value by adding the at least one learning amount to a learning value which is stored in a memory in advance; and

storing, by the controller, the predicted learning value in the memory as a final learning value, when the predicted learning value satisfies a predetermined condition.
