Vehicle and control method of vehicle
First Claim
1. A vehicle, comprising:
- a power output device that outputs driving power for driving said vehicle;
an accelerator operation detection mechanism that detects a driver'"'"'s accelerator operation;
a vehicle speed measurement unit that measures a vehicle speed;
a target vehicle speed setting module that sets a target vehicle speed equal to a vehicle speed measured by the vehicle speed measurement unit at the moment of the driver'"'"'s accelerator operation from an accelerator-on state to an accelerator-off state detected by the accelerator operation detection mechanism; and
a control module that, in the case where the target vehicle speed is not set, controls the power output device based on the driver'"'"'s accelerator operation detected by the accelerator operation detection mechanism,in the case where that the target vehicle speed is set, said control module controlling the power output device to drive said vehicle at the set target vehicle speed.

Abstract
In the vehicle of the invention, when the driver releases a depressed accelerator pedal, the drive control sets a vehicle speed V at the moment to a target vehicle speed V* (step S440). An engine and a motor for outputting driving power are controlled to drive the vehicle at the target vehicle speed V*. When the driver steps on a released brake pedal, the drive control stores the target vehicle speed V* set before the driver'"'"'s depression of the brake pedal as a previous target vehicle speed Vpre and cancels the setting of the target vehicle speed V* (steps S470 and S480). In response to the driver'"'"'s subsequent release of the brake pedal, the drive control sets the vehicle speed V at the moment to the target vehicle speed V* (step S510) and restarts constant-speed drive (cruise drive). When the driver turns a steering wheel to or over a preset degree for a left turn or a right turn, the drive control sets the previous target vehicle speed V* to the target vehicle speed V* (step S520) and restarts the constant-speed drive. This arrangement ensures easy and quick start of the constant-speed drive (cruise drive) and enables the constant-speed drive (cruise drive) according to the variation of the driving state.
