Abstract
A system for monitoring vehicle behavior based on vehicle control data includes a network access device configured to receive braking data from multiple vehicles, the braking data corresponding to vehicle braking events having a brake pressure that is equal to or greater than a threshold brake pressure and including a corresponding location. The system further includes a processor coupled to the memory and configured to determine an event of interest on a roadway by analyzing the braking data and the corresponding location, and to transmit a notification of the event of interest to at least one vehicle.
Claims19
A system for monitoring vehicle behavior based on vehicle control data, the system comprising:
- a data communication module configured to receive braking data from multiple vehicles, the braking data corresponding to vehicle braking events having a brake pressure that is equal to or greater than a threshold brake pressure and including a corresponding location;
- and
- a processor coupled to the data communication module and configured to:
- determine an event of interest on a roadway by analyzing the braking data and the corresponding location when a quantity of vehicle braking events at the corresponding location is greater than or equal to a threshold event quantity, the threshold event quantity configured to be adjusted based on the corresponding location,
- transmit a notification of the event of interest to at least one vehicle, and transmit instructions to an electronic control unit (ECU) of the at least one vehicle to change a current lane of the at least one vehicle to avoid a lane associated with the event of interest.
A system for monitoring vehicle behavior based on vehicle control data in a vehicle, the system comprising:
- at least one of a brake sensor or a brake pedal configured to detect a vehicle braking event corresponding to a brake pressure that is equal to or greater than a threshold brake pressure;
- a location sensor configured to detect a current location of the vehicle;
- a data communication module configured to communicate with a server;
- an output device configured to output data;
- and
- an electronic control unit coupled to the at least one of the brake sensor or the brake pedal, the location sensor, the data communication module, and the output device and configured to:
- transmit braking data to the server, the braking data including the vehicle braking event and a corresponding location of the vehicle during the vehicle braking event,
- receive a notification of an event of interest at an event location from the server, the notification being generated based on the braking data from at least one of the vehicle or another vehicle when a quantity of vehicle braking events at the corresponding location is greater than or equal to a threshold event quantity, the threshold event quantity configured to be adjusted based on the corresponding location,
- control the output device to output the notification of the event of interest, and
- change a current lane of the vehicle to avoid a lane associated with the event of interest.
