Abstract
Embodiments are disclosed for improving safety with parking brake actuation. In particular, embodiments inhibit or allow parking brake commands based on an operation state of a vehicle. Further, embodiments act on parking brake commands based on a health or condition of the parking brakes themselves. An example method for autonomous operation of a vehicle includes receiving a command to apply a parking brake of the vehicle; determining a vehicle operation state based on comparing a speed of the vehicle to a range of pre-determined values; configuring an instruction for engagement of the parking brake according to the vehicle operation state; determining a brake health of the parking brake; and transmitting the instruction to the parking brake to cause the parking brake to be engaged based on the brake health satisfying one or more thresholds.
