Abstract:
1. A vehicle braking device which includes a regenerative braking device and a fluid pressure braking device and is capable of performing regenerative braking and fluid pressure braking, and which changes, after braking is started, from the regenerative braking to the fluid pressure braking, wherein: when a first condition is met after the braking is started, the transition from the regenerative braking to the fluid pressure braking is started so that a fluid pressure braking force is increased linearly from 0 at a first increasing rate while the regenerative braking is simultaneously decreased linearly at a first decreasing rate, and when a second condition is met after the first condition is met, the fluid pressure braking force is increased linearly at a second increasing rate, which is higher than the first increasing rate while the regenerative braking is simultaneously decreased linearly at a second decreasing rate which is greater than the first decreasing rate, wherein the first condition is that a vehicle speed falls to or below a first threshold value after the braking is started, and wherein the second condition is that the vehicle speed further decreases and falls to or below a second threshold value, which is smaller than the first threshold value, after the first condition is met.
