Vehicle braking apparatus

摘要

A vehicle braking apparatus varies a relationship of a pressure increase characteristic of rear-wheel brake oil pressure with respect to a pressure increase characteristic of front-wheel brake oil pressure according to a determination result of a likelihood of a collision with an obstacle. Preferably, when the likelihood of a collision with an obstacle is lower than a predetermined level, the relationship of the pressure increase characteristic of the rear-wheel brake oil pressure with respect to the pressure increase characteristic of the front-wheel brake oil pressure is caused to be a relationship in which a wheel cylinder pressure of the rear wheel increases not earlier than wheel cylinder pressure of the front wheel.

主权项

1. A vehicle braking apparatus which varies a relationship of a pressure increase characteristic of a wheel cylinder pressure of rear-wheels with respect to a pressure increase characteristic of a wheel cylinder pressure of front-wheels depending on a determination result of a likelihood of collision with an obstacle, comprising:
a control unit including a computer configured to: when it is determined that collision with an obstacle is not unavoidable,
control the relationship of the pressure increase characteristic of the wheel cylinder pressure of the rear-wheels with respect to the pressure increase characteristic of the wheel cylinder pressure of the front-wheels to be a relationship in which the wheel cylinder pressure of the rear wheels increases not earlier than the wheel cylinder pressure of the front wheels, andcontrol a pressure increase start timing of the wheel cylinder pressure of the rear wheels to be later than a pressure increase start timing of the wheel cylinder pressure of the front wheels.
