CONFIGURABLE VEHICULAR TIME TO STOP WARNING SYSTEM
First Claim
1. A method for determining when to issue an alert warning to a driver of a vehicle relating to an upcoming stopping location in a road of travel, the method comprising the steps of:
- receiving a wireless message transmitted from a remote entity to the vehicle, the message containing position data relating to the stopping location in the traveled road;
retrieving GPS data relating to instantaneous vehicle position in the road of travel;
determining an instantaneous vehicle speed;
determining a travel time until the vehicle reaches the stopping location;
detecting whether the driver has initiated braking;
determining an advance notice period for issuing a warning to the driver to decelerate the vehicle comprising the travel time plus a predetermined reaction time plus a selectable driver configured increment; and
actuating a sensory warning to the driver of the vehicle if the advance notice period is less than the travel time and the driver has not initiated braking.

Abstract
A method is provided for determining when to issue an alert warning to a driver of a vehicle relating to an upcoming stopping location in a road of travel. Wireless messages transmitted from a remote entity to the vehicle are received. The messages contain information such as position data and other data affecting stopping of the vehicle. GPS data relating to instantaneous vehicle position in the road of travel is retrieved. A travel time until the vehicle reaches the stopping location is determined. A determination is made whether the driver has initiated braking. An advance notice period is determined for issuing a warning to the driver to decelerate the vehicle comprising the travel time plus a predetermined reaction time plus a selectable driver configured increment. A sensory warning to the driver of the vehicle is actuated if the advance notice period is less than the travel time and the driver has not initiated braking.

19. A vehicular warning system for alerting a driver of a vehicle of an upcoming stopping location in a road of travel, the system comprising:
-
a host vehicle receiver for receiving a remote wireless message from a remote entity transmitting unit for transmitting the wireless message, the wireless message including position data relating to a stopping location in the traveled road of the driven vehicle; a GPS receiver for determining an instantaneous vehicle position in the traveled road; a controller for determining a travel time to reach the stopping location in response to the remote wireless message data and the in-vehicle GPS, the controller determining an advance notice period for issuing a warning to the driver to initiate deceleration of the vehicle in response to travel time plus a predetermined reaction time plus a selectable driver configured increment; and a driver vehicle interface for actuating a sensory warning to the driver of the vehicle if the advance notice period is less than the travel time and the driver has not initiated braking. - View Dependent Claims (20)
