Abstract
Official abstract text for this publication.
A vehicle includes friction brakes, an electronic park brake system, and controllers. The controllers, responsive to the vehicle coming to a stop, and the vehicle being on plug, a driver door of the vehicle being open, or a driver seatbelt being unbuckled, issue a standstill friction brake request for the friction brakes and an electronic park brake request for the electronic park brake system. The controllers also, responsive to engagement of the electronic park brake system, discontinue the issue of the standstill friction brake request.
First claim
Opening claim text (preview).
What is claimed is: 1. A vehicle comprising: friction brakes; an electronic park brake system; and one or more controllers programmed to, responsive to the vehicle coming to a stop and a driver door of the vehicle being open, issue a standstill friction brake request for the friction brakes and an electronic park brake request for the electronic park brake system, and responsive to engagement of the electronic park brake system, discontinue the issue of the standstill friction brake request. 2. The vehicle of claim 1 , wherein the one or more controllers is further programmed to repeatedly issue the standstill friction brake request absent the engagement. 3. The vehicle of claim 1 , wherein the one or more controllers is further configured to, responsive to the vehicle coming to a stop and being on plug, issue the standstill friction brake request and the electronic park brake request. 4. The vehicle of claim 1 , wherein the one or more controller is further programmed to, responsive to the vehicle coming to a stop and a driver seat belt of the vehicle being unbuckled, issue the standstill friction brake request and the electronic park brake request. 5. A method for controlling a vehicle, comprising: by one or more controllers, responsive to the vehicle coming to a stop and being on plug, issuing a standstill friction brake request for friction brakes and an electronic park brake request for an electronic park brake system, and responsive to engagement of the electronic park brake system, discontinuing the issuing of the standstill friction brake request. 6. The method of claim 5 further comprising repeatedly issuing the standstill friction brake request absent the engagement. 7. The method of claim 5 further comprising, responsive to the vehicle coming to a stop and a driver door of the vehicle being open, issuing the standstill friction brake request and the electronic park brake request. 8. The method of claim 5 further comprising, responsive to the vehicle coming to a stop and a driver seat belt of the vehicle being unbuckled, issuing the standstill friction brake request and the electronic park brake request. 9. A vehicle comprising: friction brakes; an electronic park brake system; and one or more controllers programmed to, responsive to the vehicle coming to a stop and a driver seat belt of the vehicle being unbuckled, issue a standstill friction brake request for the friction brakes and an electronic park brake request for the electronic park brake system, and responsive to engagement of the electronic park brake system, discontinue the issue of the standstill friction brake request. 10. The vehicle of claim 9 , wherein the one or more controllers is further programmed to repeatedly issue the standstill friction brake request absent the engagement. 11. The vehicle of claim 9 , wherein the one or more controllers is further configured to, responsive to the vehicle coming to a stop and a driver door of the vehicle being open, issue the standstill friction brake request and the electronic park brake request. 12. The vehicle of claim 9 , wherein the one or more controllers is further configured to, responsive to the vehicle coming to a stop and being on plug, issue the standstill friction brake request and the electronic park brake request.
