Patent Images
1. A vehicle turn monitoring method comprising:
- determining with a controller an intent for a host vehicle to execute a left turn before the host vehicle begins to execute the left turn;
monitoring with the controller a location relationship between the host vehicle and a remote vehicle before the host vehicle begins to execute the left turn, the location relationship including a straight line between the host vehicle location and the remote vehicle location, and an angle between the host vehicle heading and the straight line based on a fixed coordinate system and a preselected angle direction;
evaluating with the controller a travelling condition of the host vehicle before the host vehicle begins to execute the left turn; and
determining with the controller whether to perform a threat mitigation operation before the host vehicle begins to execute the left turn based on the location relationship and the travelling condition.

15. A vehicle turn monitoring system comprising:
-
a location monitor configured to monitor a location of a host vehicle; a sensor configured to sense a travelling condition of the host vehicle; and a controller configured to determine an intent for a host vehicle to execute a left turn before the host vehicle begins to execute the left turn, monitor a location relationship between the host vehicle and a remote vehicle based on the location of the host vehicle as determined by the location monitor before the host vehicle begins to execute the left turn, the location relationship including a straight line between the host vehicle location and the remote vehicle location, and an angle between the host vehicle heading and the straight line based on a fixed coordinate system and a preselected angle direction, evaluate the travelling condition of the host vehicle as sensed by the sensor before the host vehicle begins to execute the left turn, and determine whether to perform a threat mitigation operation before the host vehicle begins to execute the left turn based on the location relationship and the travelling condition. - View Dependent Claims (16, 17, 18, 19, 20)
