Systems and methods for providing proximity alerts between vehicles and personal transportation devices
Example embodiments described in this disclosure are generally directed to systems and methods for preventing vehicle mishaps. In an example method, a vehicle receives an alert signal from a personal transportation device. A driver of the vehicle may be made aware of the alert by a sound that is produced through a speaker system of the vehicle (for example, a ringing sound produced by a bicycle bell or a beep of a motorcycle horn). In some cases, an intensity and/or a directionality of the sound produced through the speaker system may provide location and/or distance information of the personal transportation device with respect to the vehicle. The vehicle may transmit an acknowledge signal to the personal transportation device. A rider of the personal transportation device may be informed of the acknowledgement via an audio announcement through a speaker mounted on the personal transportation device.
1. A method comprising:
transmitting, by a first transceiver in a personal transportation device, an alert signal when the personal transportation device is within a threshold distance of a vehicle; and
receiving, by the first transceiver, an acknowledgement signal transmitted by a second transceiver in the vehicle in response to the alert signal,
wherein transmitting of the alert signal by the personal transportation device is initiated by a rider of the personal transportation device when the personal transportation device is within the threshold distance of the vehicle, and
wherein the alert signal is initiated by a voice command of the rider, and further wherein the threshold distance is determined by the rider.
2. The method of claim 1 , further comprising:
producing, by an audio system provided on the personal transportation device, an audio announcement to inform a rider of the personal transportation device that the alert signal has been acknowledged by the vehicle.
3. The method of claim 1 , wherein the alert signal comprises an instruction to produce an audible alert and/or a visual alert to inform a driver of the vehicle that the alert signal has been received.
4. The method of claim 1 , wherein the alert signal is automatically transmitted by the personal transportation device when the personal transportation device is within the threshold distance of the vehicle.
5. A system comprising:
a vehicle that includes a first transceiver, wherein the vehicle is an autonomous vehicle; and
a vehicle controller that is communicatively coupled to the first transceiver, the vehicle controller comprising:
a memory that stores computer-executable instructions; and
a processor configured to access the memory and execute the computer-executable instructions to perform operations comprising:
receiving an alert signal transmitted by a second transceiver provided on a personal transportation device;
transmitting to the second transceiver, an acknowledgement signal to acknowledge receipt of the alert signal; and
producing a visual acknowledgement through a light mounted upon an exterior portion of the autonomous vehicle, to inform a rider of the personal transportation device that the alert signal has been received by the autonomous vehicle.
6. The system of claim 5 , wherein the vehicle further includes an audio system, and wherein the processor is further configured to access the memory and execute the computer-executable instructions to perform operations comprising:
producing through the audio system, an audible alert to inform a driver of the vehicle that the alert signal has been received, the audible alert comprising one of a ringing sound of a bicycle bell or a beep of a motorcycle horn.
7. The system of claim 6 , wherein producing the audible alert comprises the processor acting upon an instruction contained in the alert signal by executing a sound file stored in the memory.
8. The system of claim 5 , wherein producing the visual acknowledgement comprises the processor executing a light flashing sequence stored in the memory.
