Abstract

In one embodiment, a system determines activation parameters for an autonomous driving vehicle (ADV), where the activation parameters include historical usages of a primary brake system or a secondary brake system. In response to determining that a brake is to be applied, the system determines whether to activate a primary or a secondary brake system based on the activation parameters. The system sends an activation flag to activate the primary or the secondary brake system based on the determining whether to activate the primary or the secondary brake system. The system sends a brake command to the primary and the secondary brake system to activate either the primary or the secondary brake system according to the activation flag.
