Collision alert systems and methods for micromobility vehicles

A downed micromobility vehicle notification system for an micromobility vehicle comprising:

• a speed sensor configured to sense a speed of the micromobility vehicle;
• a tilt sensor configured to sense vertical orientation data of the micromobility vehicle indicating whether the micromobility vehicle is in an upright position or a horizontal position;
• at least one notification device;
• and
• a controller in communication with the speed sensor, the tilt sensor, and the at least one notification device, the controller being configured to (i) receive the speed of the micromobility vehicle from the speed sensor, (ii) receive the vertical orientation data of the micromobility vehicle from the tilt sensor, and (iii) generate a downed micromobility vehicle notification by activating the at least one notification device in response to the speed of the micromobility vehicle indicating that the micromobility vehicle is not moving and the vertical orientation data indicating that the micromobility vehicle is in the horizontal position.

A collision warning system for a micromobility vehicle comprising:

• at least one proximity sensor mounted to the micromobility vehicle and configured to sense a distance to an object located in front of the micromobility vehicle;
• a speed sensor configured to sense a speed of the micromobility vehicle;
• at least one warning device;
• and
• a controller in communication with the at least one proximity sensor, the speed sensor, and the at least one warning device and having a bypass mode and a warning mode, the controller being configured to (i) receive the speed of the micromobility vehicle from the speed sensor, (ii) compare the speed of the micromobility vehicle with a predetermined speed threshold, (iii) enter the bypass mode in response to the speed of the micromobility vehicle being less than the predetermined speed threshold, and (iv) enter the warning mode in response to the speed of the micromobility vehicle being greater than the predetermined speed threshold;
• wherein, while in the bypass mode, the controller is further configured to not activate the at least one warning device;
• and
• wherein, while in the warning mode, the controller is further configured to (v) receive the distance to the object from the at least one proximity sensor, (vi) determine a closing velocity to the object based on the speed of the micromobility vehicle received from the speed sensor, (vii) calculate an estimated time until a potential collision with the object based on the distance to the object and the closing velocity, (viii) compare the estimated time until the potential collision with the object with a predetermined time threshold, and (ix) generate a collision warning by activating the at least one warning device to alert a rider of the micromobility vehicle of the potential collision with the object in response to the estimated time until collision being less than the predetermined time threshold.
