Abstract
A vehicle brake device is configured to limit a drop in a final target braking force when an abrupt deceleration is performed by the driver. The vehicle brake device has a brake operating element, a master cylinder and a controller. The brake operating element is operated by the driver of a vehicle. The master cylinder is operatively coupled to the brake operating element to generate a fluid pressure in accordance with an operation of the brake operating element. The controller calculates a target deceleration rate based on the fluid pressure of the master cylinder and controls a braking force of the vehicle in accordance with the target deceleration rate. The controller is limits a decrease in the target deceleration rate during an abrupt deceleration caused by the operation of the brake operating element by the driver.
