One or more embodiments of the present disclosure relate to automatic parking brake actuation and fault detection. Embodiments for improving the safety of parking brake actuation are disclosed. In particular, embodiments disable or allow parking brake commands based on an operating state of the vehicle. Further, embodiments take action according to the parking brake command based on the health or condition of the parking brake itself. An example method for autonomous operation of a vehicle includes receiving a command to apply a parking brake of the vehicle; determining a vehicle operating state based on comparing the speed of the vehicle to a predetermined range of values; configuring instructions for engaging the parking brake according to the vehicle operating condition; determining a brake health of the parking brake; and sending instructions to the parking brake to cause the parking brake to engage based on the brake health satisfying the one or more thresholds.

    本公开的一个或多个实施例涉及自动驻车制动器致动和故障检测。公开了用于提高驻车制动器致动的安全性的实施例。具体地,实施例基于车辆的操作状态,禁用或允许驻车制动器命令。此外,实施例基于驻车制动器本身的健康状况或条件,根据驻车制动器命令采取行动。一种用于车辆的自主操作的示例方法,包括:接收用以应用车辆的驻车制动器的命令;基于将车辆的速度与预定值范围进行比较,确定车辆操作状态;根据车辆操作状态,配置用于接合驻车制动器的指令;确定驻车制动器的制动器健康状况;以及基于制动器健康状况满足一个或多个阈值,向驻车制动器发送用以引起驻车制动器接合的指令。
