Title:
VEHICLE AND CONTROL METHOD THEREOF
Document Type and Number:
Japanese Patent JP2009214583
Kind Code:
A
Abstract:

To properly start from a brake-hold state due to a break-hold instruction.

When a brake hold switch is turned on for instructing to hold a brake even after returning a brake pedal after a vehicle stops on an upslope or the like, a prescribed driving force distribution rate (for example, rear wheel side 60% with respect to front wheel side 40%) is set to target braking force distribution rates Kbf* and Kbr* of front an rear wheels (S150), the sum of the braking torque of the front and rear wheels is stored, the rate of the brake oil pressures of the front wheels and rear wheels is adjusted to the target braking force distribution rates Kbf* and Kbr*, and brake hold control is started by controlling a brake actuator to hold the stop state (S160), and when accelerator opening Acc becomes a release decision threshold or more, the brake oil pressures of the front and rear wheels are released, the engine is controlled so that the request torque can be output to the front and rear wheels, and driving torque based on the prescribed driving force distribution rate is output to the front and rear wheels. Thus, a vehicle is started while suppressing the drag of the front and rear wheels.
