Abstract
Control apparatus (and a control method) for a vehicle, the vehicle including: an internal combustion engine (EG); a brake booster (21) in which an intake negative pressure of the internal combustion engine is used; and a brake master cylinder (22) connected to an onboard hydraulic pressure actuator (33), the control apparatus comprising: pressure detecting means (27) for detecting a fluid pressure of the brake master cylinder; driving state detecting means (133) for detecting the driving state of the internal combustion engine; and control means (11) for retarding an ignition timing with a throttle valve (114) of the internal combustion engine opened in a case where the driving state detected by the driving state detecting means is in the idle driving state during a cold state of the internal combustion engine and for driving the fluid pressure actuator to assist the brake master cylinder in a case where the fluid pressure detected by the pressure detecting means is equal to or lower than a predetermined value during the idling state of the engine and during the cold state of the engine.

9. A control apparatus for a vehicle, comprising:
-
an internal combustion engine; a brake booster using an intake negative pressure of the internal combustion engine; a brake master cylinder connected to a fluid pressure actuator mounted in the vehicle; pressure detecting means for detecting a fluid pressure of the brake master cylinder; driving state detecting means for detecting a driving state of the internal combustion engine; vehicle stop determining means for determining whether the vehicle is stopped; and control means for performing a pressure increase for the fluid pressure of the brake master cylinder using the fluid pressure actuator, in a case where the driving state detected by the driving state detecting means is an idle driving state during a cold of the internal combustion engine and the vehicle stop determining means determines that the vehicle is stopped, opening a throttle valve of the internal combustion engine and retarding an ignition timing, in a state in which the pressure increase is performed. - View Dependent Claims (10, 11)

12. A control method for a vehicle, the vehicle comprising:
- an internal combustion engine;
a brake booster using an intake negative pressure of the internal combustion engine; and a brake master cylinder connected to a fluid pressure actuator mounted in the vehicle, the control method comprising; detecting a fluid pressure of the brake master cylinder; detecting a driving state of the internal combustion engine; determining whether the vehicle is stopped; and performing a pressure increase for the fluid pressure of the brake master cylinder using the fluid pressure actuator, in a case where the detected driving state is an idle driving state during a cold of the internal combustion engine and the vehicle is determined to be stopped, opening a throttle valve of the internal combustion engine and retarding an ignition timing, in a state in which the pressure increase is performed. - View Dependent Claims (13, 14)
