Abstract

When the regenerative torque obtained by the regenerative driving of the electric motor reaches a predetermined threshold or more, a predetermined notification is made and a history of the fact that the predetermined notification has been made is recorded, and the allowable maximum input power that can be input to the power storage device when the predetermined notification is made is stored as the control input power. When there is a history indicating that the predetermined notification has been made, the predetermined notification is performed again when the regenerative torque is equal to or greater than the predetermined threshold and the absolute value of the allowable maximum input power is less than the absolute value of the control input power.

Claims (6)

1 . An in-vehicle control device to be mounted on an electrified vehicle including an electric motor for traveling and a power storage device configured to exchange electric power with the electric motor, wherein the in-vehicle control device is configured to

when regenerative torque obtained by regenerative driving of the electric motor reaches a predetermined threshold or more, perform a predetermined notification and store a record of the predetermined notification, and store, as control input power, maximum permissible input power that is inputtable to the power storage device when the predetermined notification is performed, and

in a case where the record of the predetermined notification is present, perform the predetermined notification again when the regenerative torque is the predetermined threshold or more and an absolute value of the maximum permissible input power is less than an absolute value of the control input power.

2 . The in-vehicle control device according to claim 1 , wherein an upper limit of the control input power is guarded by the maximum permissible input power.

3 . The in-vehicle control device according to claim 1 , wherein the predetermined threshold is set based on a shift position.

4 . The in-vehicle control device according to claim 1 , wherein the predetermined notification is a notification that prompts a driver to perform a brake operation.
