Abstract
Notifying a driver of a number of hydraulic pressure support events. In one example, a system includes a parking brake assembly; a human-machine interface; and a parking brake electronic processor configured to generate a command to apply one or more braking components of the parking brake assembly to at least one wheel of the vehicle and generate a request for additional hydraulic pressure support. The system also includes a host electronic processor configured to receive the request for additional hydraulic pressure support; generate a command to build extra hydraulic pressure; and provide the command to the pump motor. The host electronic processor is also configured to increment a counter indicating a number of hydraulic pressure support events performed; compare the counter to a threshold value; and provide an alert to the driver via the human-machine interface when the counter exceeds the threshold value.
