Title:
VEHICULAR BRAKING DEVICE
Document Type and Number:
Japanese Patent JP2019081464
Kind Code:
A
Abstract:
To provide a vehicular braking device that can suppress decrease in reserved electric energy of an auxiliary electric power source while allowing an occupant to early recognize a failure of a main electric power source.SOLUTION: The vehicular braking device comprises; an electric brake booster 43 that can brake a vehicle by driving a motor 32; a main electric power source 11 that can supply electric power to the electric brake booster 43; a capacitor 21 that can supply electric power to the electric brake booster 43; an ECU 5 that can control electric power to be supplied to the electric brake booster 43; and an electric power state detecting part 53 that can detect whether function of the main electric power source 11 deteriorates or stops. The ECU 5 sets target electric power supply amounts E to the electric brake booster 43 corresponding to target deceleration D for the vehicle, and corrects the target electric power supply amounts E to decrease the amounts when the electric power state detecting part 53 detects that the function of the main electric power source 11 deteriorates or stops.SELECTED DRAWING: Figure 5
