Negative pressure control apparatus for brake booster |
摘要 |
A negative pressure control apparatus for a brake booster is provided which can maintain a required negative pressure in the brake booster without unnecessarily increasing the negative pressure of the brake booster. The apparatus has a negative pressure controller for controlling the negative pressure in a negative pressure chamber of the brake booster toward a predetermined target value. A pedal operation determining part determines whether or not both an accelerator pedal and a brake pedal are depressed. When both the accelerator pedal and the brake pedal are depressed, a target negative pressure setting part sets the predetermined target value to be larger than a value used in a regular situation.
