Abstract

A method and apparatus for alerting a vehicle driver of a primary operating condition in a vehicle, includes detecting the primary operating condition. A primary warning indicator is then activated when the primary operating condition is detected. When a secondary operating condition is detected while the primary warning indicator is activated a secondary indicator is activated. The primary and secondary warning indicators are deactivated when the primary operating condition ceases to exist.

Claims

1. A method for alerting a vehicle driver of an applied brake in a vehicle, the method comprises the steps of:

detecting when the parking brake is applied;

activating a visual warning indicator when said parking brake is applied;

detecting a secondary operating condition indicative of a transmission clutch actuation;

activating a secondary warning indicator when both said parking brake is applied and said secondary operating condition is detected; and

deactivating said visual warning indicator and said secondary warning indicator when said parking brake is no longer applied.

2. A method for alerting a vehicle driver of an applied brake in a vehicle, the method comprises the steps of:

detecting when the parking brake is applied;

activating a visual warning indicator when said parking brake is applied;

detecting a secondary operating condition indicative of a transmission gear selection;

activating a secondary warning indicator when both said parking brake is applied and said secondary operating condition is detected; and

deactivating said visual warning indicator and said secondary warning indicator when said parking brake is no longer applied.

3. An apparatus for alerting a vehicle driver of an applied parking brake in a vehicle, said apparatus comprising:

first means for detecting when the parking brake is applied;

second means for detecting a secondary operating condition indicative of a transmission clutch actuation;

processor means operatively connected with said first and second means for activating a visual warning indicator when said parking brake is applied and activating a secondary warning indicator when both said parking brake is applied and said secondary operating condition is detected and deactivating said visual warning indicator and said secondary warning indicator when said parking brake is no longer applied.

4. A apparatus according to claim 3, wherein said secondary warning indicator includes means for generating an audible tone.

5. A apparatus according to claim 3, wherein said visual warning indicator is an illuminated warning lamp.

6. An apparatus for alerting a vehicle driver of an applied parking brake in a vehicle, said apparatus comprising:

first means for detecting when the parking brake is applied;

second means for detecting a secondary operating condition indicative of a transmission gear selection;

processor means operatively connected with said first and second means for activating a visual warning indicator when said parking brake is applied and activating a secondary warning indicator when both said parking brake is applied and said secondary operating condition is detected and deactivating said visual warning indicator and said secondary warning indicator when said parking brake is no longer applied.
