Abstract:
1. A vehicle brake device for braking a vehicle by the stepping manipulation of a brake pedal, comprising: collision detection means for detecting a collision of the vehicle; pedal pushing-up detection means for detecting, after occurrence of the collision of the vehicle detected by the collision detection means, actual pushing-up of the brake pedal which is being stepped on by the driver; pedal control means for withdrawing the brake pedal when the pushing-up of the brake pedal is detected by the pedal pushing-up detection means; and stepping state detection means for detecting the stepping state of the brake pedal; wherein the pedal pushing-up detection means detects the pushing-up of the brake pedal when the change from a first stepping state to a second stepping state is detected by the stepping state detection means after the collision of the vehicle is detected by the collision detection means; the pedal control means withdraws the brake pedal as the stepping state of the brake pedal detected by the stepping state detection means is maintained in the second stepping state which has caused the pedal pushing-up detection means to detect the pushing-up of the brake pedal; and the second stepping state is a state that a pedal reaction force necessary to keep the body balance of the driver is being generated and that an excess force is not being exerted on the driver's foot.
