Abstract: A master pressure control device of an electric booster sets an upper limit of current supplied to an electric motor in accordance with an operation amount of an input member to a current limit value A when a condition for limiting the driving of the electric motor is satisfied due to a decrease of voltage of a vehicle power source. The master pressure control device sets the upper limit of the current supplied to the electric motor in accordance with the operation amount of the input member to a current limit value B when the condition for limiting the driving of the electric motor is cancelled due to restoration of the voltage of the vehicle power source to normal while a brake pedal is operated. The current limit value B is larger than the current limit value A used when the driving of the electric motor is limited.

Abstract: With the use of electric power supplied from a vehicle power source, an electric motor is controlled based on a movement amount of an input rod by a master-pressure control device. A primary piston is thrust through an intermediation of a ball-screw mechanism to generate brake fluid pressure in a master cylinder. The brake fluid pressure generated by the master cylinder is fed-back by an input piston through an intermediation of the input rod to a brake pedal. When system end conditions such as the OFF state of the ignition switch are satisfied, the master-pressure control device executes power-supply interruption control to interrupt the vehicle power source and supply necessary electric power from an auxiliary power source, to thereby continue brake control with electric power stored in the auxiliary power source.

The system detects size of a leading vehicle and insolation around the own vehicle. An appropriate following distance deriving means derives the appropriate following distance so that the appropriate following distance becomes longer when the size of the leading vehicle detected by the vehicle size detecting means is large and the appropriate following distance becomes longer at higher brightness detected by the insolation detecting means.
