Title:
AUTOMOBILE BRAKE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/069681
Kind Code:
A1
Abstract:
The objective of the present invention is to provide a novel automobile brake system with which it is possible for braking states of front wheels and rear wheels to be appropriately and efficiently controlled using a standby power supply when a power supply system fails. This automobile brake system is provided with a standby power supply 36 to be used when a main power supply 35 cannot supply necessary electric power to electric component elements of a front wheel side braking mechanism 4 and a rear wheel side braking mechanism 5, wherein, when the necessary electric power cannot be supplied from the main power supply 35, an electric power switching and adjusting means 37 causes electric power to be supplied from the standby power supply 36 to the electric component elements of the rear wheel side braking mechanism 5, without causing electric power to be supplied to the electric component elements of the front wheel side braking mechanism 4. It is thus possible to obtain a novel brake system with which it is possible for the braking states of the front wheels and the rear wheels to be appropriately and efficiently controlled using the standby power supply when the power supply system fails.
