Braking sound augmentation

A system for providing audible notification to a user within a vehicle when braking sub-systems within the vehicle are actuated, comprising:

• a system controller in communication with a vehicle controller, a plurality of sensors within the vehicle, an infotainment system within the vehicle and a plurality of braking sub-systems within the vehicle, the system controller adapted to:
• identify at least one actuated braking sub-system from the plurality of braking sub-systems;
• calculate, for each of the at least one actuated braking sub-system, a delta representing a relative influence of each of the at least one actuated braking sub-system;
• select, based on the calculated deltas, a dominant one of the at least one actuated braking sub-system;
• select an audible signal associated with the dominant one of the at least one actuated braking sub-system;
• select a volume at which the selected audible signal is to be broadcast;
• and
• broadcast, via the vehicle infotainment system, the audible signal.

A vehicle having a system for providing audible notification to a user within the vehicle when braking sub-systems within the vehicle are actuated, the system comprising:

• a system controller in communication with a vehicle controller, a plurality of sensors within the vehicle, an infotainment system within the vehicle and a plurality of braking sub-systems within the vehicle, the system controller adapted to:
• identify at least one actuated braking sub-system from the plurality of braking sub-systems by at least one of:
• determine actuation of an antilock braking sub-system;
• determine actuation of a traction control sub-system;
• determine actuation of an engine drag control sub-system;
• and
• determining actuation of an electronic stability control sub-system;
• collect, via a plurality of sensors within the vehicle, a pedal position for a brake pedal within the vehicle, a pedal position for an accelerator pedal within the vehicle, a surface friction for a road surface on which the vehicle is traveling, a yaw deviation of the vehicle and an angular position of a steering wheel within the vehicle;
• receive, from the vehicle controller, a level of a torque request for the engine drag control sub-system;
• calculate, for each of the at least one actuated braking sub-system, a delta representing a relative influence of each of the at least one actuated braking sub-system by at least one of:
• calculate a delta for the antilock braking sub-system based on the brake pedal position and the surface friction of the road surface;
• calculate a delta for the traction control sub-system based on the accelerator pedal position and the surface friction of the road surface;
• calculate a delta for the engine drag control sub-system based on the torque request and the surface friction of the road surface;
• and
• calculate a delta for the electronic stability control sub-system based on yaw deviation, steering wheel angle and the surface friction of the road surface;
• select, based on the calculated deltas, a dominant one of the at least one actuated braking sub-system;
• access a database within the system controller, wherein the database includes a plurality of audible signals stored therein, one audible signal associated with each of the plurality of braking sub-systems;
• select the one of the plurality of audible signals that is associated with the dominant one of the at least one actuated braking sub-system;
• measure, based on input from the plurality of sensors within the vehicle and feedback from the vehicle controller, a level of actuation of the dominant one of the at least one actuated braking sub-system;
• select a volume at which the selected audible signal is to be broadcast based on the measured level of actuation of the dominant one of the at least one actuated braking sub-system;
• broadcast, via the vehicle infotainment system, the audible signal;
• and
• continuously, throughout broadcasting of the audible signal:
• monitor, based on input from the plurality of sensors within the vehicle and feedback from the vehicle controller, the level of actuation of the dominant one of the at least one actuated braking sub-system;
• and
• adjust the volume at which the selected audible signal is to be broadcast as the level of actuation of the dominant one of the at least one actuated braking sub-system varies.
