Abstract
A vehicle on-board unit of a host vehicle is configured to communicate with other vehicle to alert the driver of a potential braking situation in a preceding vehicle. The vehicle on-board unit has an incoming message receiving section, an incoming message relevancy section and a driver warning section. The incoming message receiving section receives a preceding vehicle message containing throttle release data of a preceding vehicle located in front of the host vehicle. The incoming message relevancy section performs a relevancy determination of the throttle release data received. The driver warning section selectively alerts a driver of the host vehicle of a potential braking situation of the preceding vehicle based upon the relevancy determination.
Claims19
A vehicle on-board unit comprising:
- a vehicle traveling condition detecting section configured to detect at least one vehicle traveling condition of a host vehicle that is equipped with the vehicle on-board unit, with the vehicle traveling condition detecting section monitoring a host vehicle location as part of the vehicle traveling condition to determine a travel lane of the host vehicle using a plurality of detection results of the host vehicle location;
- an incoming message receiving section configured to receive a preceding vehicle message containing throttle release data of a preceding vehicle located in front of the host vehicle equipped with the vehicle on-board unit;
- an incoming message relevancy section configured to perform a relevancy determination of the throttle release data received by the incoming message receiving section;
- a driver warning section configured to selectively alert a driver of the host vehicle of a potential braking situation of the preceding vehicle based upon the relevancy determination of the incoming message relevancy section;
- and
- a relevancy adjustment section configured to selectively adjust the relevancy determination of the throttle release data when the driver warning section alerts the driver of the host vehicle of the potential braking situation of the preceding vehicle based on the travel lane.
A method for early warning to a host vehicle driver of potential braking situation of a preceding vehicle comprising:
- detecting a host vehicle traveling condition of a host vehicle, the detecting of the host vehicle traveling condition at least including monitoring a host vehicle location as part of the vehicle traveling condition to determine a travel lane of the host vehicle using a plurality of detection results of the host vehicle location;
- receiving a preceding vehicle message containing throttle release data of the preceding vehicle located in front of a host vehicle;
- performing a relevancy determination of the throttle release data that was received by the host vehicle at least partially based on the travel lane of the host vehicle that was determined;
- and
- selectively warning the driver of the host vehicle of a potential braking situation of the preceding vehicle based upon the relevancy determination of the throttle release data.
