Systems and methods for notifying other road users of a change in vehicle speed

A non-transitory computer-readable medium for notifying other road users of a change in speed of a vehicle and storing instructions that when executed by one or more processors cause the one or more processors to:

• receive sensor data from one or more sensors;
• detect, from the sensor data, one or more other road users;
• measure, from the sensor data, a gaze pattern of at least one of the one or more other road users;
• determine, based at least in part on the measured gaze pattern, a lag time between a commencement of the change in speed of the vehicle and an estimated moment at which the at least one of the one or more other road users perceives the change in speed of the vehicle;
• and
• output a signal from the vehicle at a time that, relative to the commencement of the change in speed of the vehicle, is delayed by the lag time to notify the at least one of the one or more other road users of the change in speed of the vehicle.

A method of notifying other road users of a change in speed of a vehicle, the method comprising:

• receiving sensor data from one or more sensors;
• detecting, from the sensor data, one or more other road users;
• measuring, from the sensor data, a gaze pattern of at least one of the one or more other road users:
• determining, based at least in part on the measured gaze pattern, a lag time between a commencement of the change in speed of the vehicle and an estimated moment at which the at least one of the one or more other road users perceives the change in speed of the vehicle;
• and
• outputting a signal from the vehicle at a time that, relative to the commencement of the change in speed of the vehicle, is delayed by the lag time to notify the at least one of the one or more other road users of the change in speed of the vehicle.
