Vehicle gate ajar notification method
A vehicle user is notified of a rear gate ajar condition so that the user can take corrective action by opening and then re-closing the rear gate. The method includes the steps of determining that the rear gate latch has engaged a latch striker but has not reached a fully latched position; operating a vehicle mounted signaling device that is cognizable by a user while still standing at the rear gate so that the user will receive immediate notification that the rear gate latch has not reached the fully latched position, thereby enabling the user to take immediate corrective action by opening and then re-closing the gate to attempt a fully latched position of the rear gate latch; and then, if the vehicle is started without the lift gate operator having taken corrective action to obtain full latching of the rear gate latch, energizing a lift gate ajar light on the instrument panel so that the vehicle driver is notified to take corrective action before driving away.
1. A method for alerting a vehicle user of a rear gate ajar condition, comprising:
determining that the rear gate latch has engaged a latch striker but has not reached a fully latched position;
operating a vehicle mounted signaling device that is cognizable by the user standing at the rear gate so that the user will receive immediate notification that the rear gate latch has not reached the fully latched position, thereby enabling the user to take immediate corrective action by opening and then re-closing the gate to attempt a fully latched position of the rear gate latch;
and then, if the vehicle is started without the user having taken corrective action to obtain full latching of the rear gate latch, energizing a rear gate ajar light on the instrument panel so that the vehicle driver is notified to take corrective action before driving away.
2. The method of claim 1 further comprising the operating of the vehicle mounted signaling device being an energization of at least the vehicle horn.
3. The method of claim 1 further comprising the operating of the vehicle mounted signaling device being an energization of at least the vehicle rear lights.
4. The method of claim 1 further comprising the operating of the vehicle mounted signaling device being an energization of both the vehicle horn and the rear lights.
5. The method of claim 1 further comprising determining that the rear gate latch has engaged a latch striker but has not reached a fully latched position via monitoring of switches or sensors associated with the rear gate latch.
6. The method of claim 5 further comprising monitoring the switches to determine that a fork bolt of the latch has moved from an unlatched position to a secondary latched position and has not reached a primary fully latched condition within a predetermined time of having reached the secondary latched position.
7. A method for alerting a vehicle user of a rear gate ajar condition, comprising:
determining whether a rear gate latch for latching the rear gate has reached a fully latched position or remained in a secondary partially latched position;
if the rear gate latch has remained in the secondary partially latched position, then energizing a vehicle horn or energizing a rear light on the vehicle to give immediate notification to the user standing at the rear gate that the rear gate latch has remained in the secondary latched position, thereby enabling the user to take immediate corrective action by opening and then re-closing the rear gate to attempt to achieve fully latched position of the rear gate latch;
and, if the vehicle is started without the user having taken corrective action to achieve full latching of the rear gate latch, energizing a rear gate ajar light on the instrument panel so that the vehicle driver is notified to take corrective action before driving away.
8. The method of claim 7 further comprising determining that the rear gate has remained in the secondary partially latched position and has not reached a fully latched position via monitoring of switches or sensors associated with the rear gate latch.
9. The method of claim 8 further comprising monitoring the switches to determine that a fork bolt of the latch has moved from an unlatched position to a secondary latched position and has not reached a primary fully latched condition within a predetermined time of having reached the secondary latched position.
10. A method for alerting a vehicle user of a rear gate ajar condition, comprising:
providing a rear gate latch having a fork bolt for engaging with a striker pin, said rear gate latch having switches or sensors associated therewith to sense the position of a fork bolt;
providing a controller for monitoring the switches or sensors to determine that the fork bolt has moved from an unlatched position to a secondary partially latched positions but not reached a fully latched position within a predetermined time;
and if the rear gate latch has not reached the fully latched position within the predetermined time, then energizing a vehicle horn or energizing a rear light on the vehicle to give immediate notification to the user while the rear gate operator is still standing at the rear gate, thereby enabling the user to take immediate corrective action by opening and then re-closing the gate to attempt to achieve fully latched position of the rear gate latch;
and if the vehicle is started without the user having taken corrective action to achieve full latching of the rear gate latch, energizing a rear gate ajar light on the instrument panel so that the vehicle driver is notified to take corrective action before driving away.
