Hybrid vehicle and control method thereof
First Claim
1. A hybrid vehicle, comprising:
- an internal combustion engine configured to output power for driving;
a motor configured to output power for driving;
an accumulator configured to transmit electric power to and from the motor;
an accelerator operation amount detector configured to acquire an amount of a driver'"'"'s accelerator operation;
a drive mode selector configured to select an object drive mode between a first drive mode for ordinary driving and a second drive mode having a tendency of a better response of power output to the driver'"'"'s accelerator operation than a response in the first drive mode;
an auto cruise selector configured to give an instruction for enabling a preset auto cruise function; and
a controller configured to, in the case of no instruction for enabling the preset auto cruise function, control the internal combustion engine and the motor to ensure output of a power equivalent to a driving force demand, which is set based on the acquired amount of the driver'"'"'s accelerator operation and a driving force setting restriction corresponding to either the first drive mode or the second drive mode selected as the object drive mode, and, in the case of the instruction for enabling the preset auto cruise function, to control the internal combustion engine and the motor to ensure output of a power equivalent to the driving force demand, which is set based on a restriction for execution of the preset auto cruise function without using a driving force setting restriction corresponding to the second drive mode, regardless of selection of either the first drive mode or the second drive mode as the object drive mode.

Abstract
During execution of an auto cruise function, in response to selection of a power mode, when an measured accelerator opening Acc is less than a preset opening Accref, a hybrid vehicle of the invention sets a power mode cancellation flag Fpmc to 1 and a power mode enabling flag Fpm to 0 (steps S540 and S550). This prohibits the use of an accelerator opening setting map in the power mode for execution of the auto cruise function. In the power mode, in response to an instruction for enabling the auto cruise function, the hybrid vehicle keeps the power mode enabling flag Fpm to the setting of 1 (step S560) as long as the measured accelerator opening Acc is not less than the preset opening Accref. This allows the use of the accelerator opening setting map in the power mode for execution of the auto cruise function.

- an internal combustion engine configured to output power for driving;
a motor configured to output power for driving;
an accumulator configured to transmit electric power to and from the motor;
an accelerator operation amount detector configured to acquire an amount of a driver'"'"'s accelerator operation;
