Abstract
A method of initializing a brake-by-wire system is provided. The method includes connecting multiple braking actuators to a controller to allow for communication between the braking actuators and the controller. The braking actuators are associated with one or more wheels of a vehicle. Subsequent to connecting the multiple braking actuators to a controller, the method includes dynamically assigning a primary identifier to the braking actuators using the controller.
Claims20
A method of initializing a brake-by-wire system, the method comprising:
- connecting multiple braking actuators to a controller to allow for communication between the braking actuators and the controller, the braking actuators being associated with one or more wheels of a vehicle;
- energizing the braking actuators in multiple power-enabling steps, the controller signaling a power source during a first power-enabling step to energize only some or one of the braking actuators by sending a first individual activation signal from the power source to the only some or one of the braking actuators during the first power-enabling step and the controller signaling the power source during a second power-enabling step to energize only some or one of the other braking actuators by sending a second individual activation signal from the power source to the only some or one of the other braking actuators during the second power-enabling step, the second individual activation signal sent from the power source being separate from the first individual activation signal sent from the power source;
- and
- assigning a primary identifier to the only some or one of the braking actuators using the controller after the associated power-enabling steps.
A brake-by-wire system for a vehicle including wheels and one or more braking actuators associated with one or more of the wheels, the brake-by-wire system comprising:
- a first braking actuator;
- a second braking actuator;
- a power source connected to the first and second braking actuators;
- and
- a controller connected to the power source, the controller configured to selectively identify the first and second braking actuators using the power source and assign a primary identifier to each of the first and second braking actuators for use in selectively controlling the first and second braking actuators;
- wherein the controller signals the power source to energize the first actuator during a first power-enabling step by sending a first individual activation signal to the first actuator and then the controller signals the power source to energize the second actuator during a second power-enabling step by sending a second individual activation signal to the second actuator, the second individual activation signal sent by the power source to the second actuator being separate from the first individual activation signal sent by the power source to the first actuator.
