US 11,305,747 B1 · Control for brake system of vehicle

Abstract

Methods and systems for controlling the parking brakes of a vehicle are provided. The system comprises a first brake unit; a second brake unit; a third brake unit; a fourth brake unit; a first controller powered by a first power source; a second controller powered by a second power source and communicatively coupled to the first controller via a first and second communication link; and a third controller powered by the first power source and communicatively coupled to the first controller via a third communication link and to the second controller via a fourth communication link, wherein the second controller, based at least in part on a signal received from the first controller, operates the first brake unit and the fourth brake unit, and the third controller, based at least in part on the signal received from the first controller, operates the second brake unit and the third brake unit.

8 more elements

A method implemented by a vehicle having a brake system, the method comprising:

transmitting, by a first controller of the vehicle, a command to at least one of a second controller or a third controller of the vehicle to operate the brake system;
operating, using the second controller, a first brake unit and a fourth brake unit of the brake system based at least in part on a status of the first controller;
and
operating, using the third controller, a second brake unit and a third brake unit of the brake system based at least in part on the status of the first controller and a status of the second controller.

1 more element

One or more non-transitory computer-readable media storing instructions that, when executed, cause one or more processors to perform operations comprising:

transmitting, by a first controller of a vehicle, a command to at least one of a second controller or a third controller of the vehicle to operate a brake system of the vehicle;
operating, using the second controller, a first brake unit and a fourth brake unit of the brake system based at least in part on a status of the first controller;
and
operating, using the third controller, a second brake unit and a third brake unit of the brake system based at least in part on the status of the first controller and a status of the second controller.
