Abstract

A passenger protection system for a vehicle includes a vehicle sensor control system having at least one processor and computerized memory storing vehicle control software therein, wherein the vehicle control software receives input data from a plurality of vehicle sensors. A digital control sequence is triggered in the software by a presence of at least one occupant other than a driver in the vehicle, with the digital control sequence activating and de-activating an alert system on a door of the vehicle. The alert system includes at least one of an audible alert and/or a visible alert and/or haptic alert on the door of the vehicle.

First claim

The invention claimed is:

1. A passenger protection system for a vehicle, comprising:
a vehicle control system comprising at least one processor and computerized memory storing vehicle control software therein, wherein the vehicle control software receives input data from a plurality of vehicle sensors;
a digital control sequence triggered in the software by a presence of at least one occupant other than a driver in the vehicle, the digital control sequence activating and de-activating an alert system on a door of the vehicle, the alert system comprising at least one of an audible alert and/or a visible alert and/or a haptic alert on the door of the vehicle;
wherein the digital control sequence is in electronic communication with an occupant monitoring system comprising at least one sensor detecting the presence of the occupant other than the driver in the vehicle;
wherein the sensor comprises at least one imaging device identifying the driver and the at least one occupant other than the driver; and
wherein the alert system comprises a haptic switch connected to the door of the vehicle in a position configured to be touched by the driver prior to exiting the vehicle.

2. The passenger protection system of claim 1 , wherein the digital control sequence activates the alert system in an order comprising the visible alert, followed by the haptic alert, followed by the audible alert.

3. The passenger protection system of claim 1 , wherein the alert system on the door comprises a visible warning button triggered to alert the driver of other occupants in the vehicle prior to the driver exiting the vehicle.

4. The passenger protection system of claim 3 , wherein the visible warning button comprises a bypass function triggered by a touch event by the driver.

5. The passenger protection system of claim 1 , wherein the haptic switch comprises a manual bypass function triggered by a touch event by the driver.

6. The passenger protection system of claim 1 , wherein the alert system comprises an audible warning function emanating from the door of the vehicle when the door is opened.

7. The passenger protection system of claim 6 , wherein a speaker in the door provides the audible warning function.

8. The passenger protection system of claim 1 , wherein the audible alert and/or the visible alert and/or the haptic alert are deactivated by at least one reset button.

9. A passenger protection system for a vehicle, comprising:
a vehicle control system comprising at least one processor and computerized memory storing vehicle control software therein, wherein the vehicle control software receives input data from a plurality of vehicle sensors;
at least one imaging device configured for identifying a driver and at least one occupant other than the driver;
an occupant monitoring system connected to a plurality of sensors and the imaging device to identify a presence of the driver and the at least one other occupant in the vehicle, the occupant monitoring system further comprising additional sensors classifying the driver and the other occupant according to a passenger classification system stored in the software;
an alert system comprising at least one of an audible alert component and/or a visible alert component and/or a haptic alert component on the at least one door of the vehicle;
a digital control sequence triggered in the software by a presence of the at least one occupant other than a driver in the vehicle, the digital control sequence activating and de-activating the alert system on at least one door of the vehicle, wherein the digital control sequence is in electronic communication with the occupant monitoring system;
wherein the alert system comprises a haptic switch connected to a door of the vehicle in a position configured to be touched by the driver or a respective other occupant prior to exiting the vehicle; and
wherein the additional sensors classifying the driver and the at least one other occupant configure the software to utilize the digital control sequence on a selected door of the vehicle.

10. The passenger protection system of claim 9 wherein the additional sensors classify the driver and the other occupant according to weight or size.

11. The passenger protection system of claim 10 , wherein the weight or size indicates a classification selected from a one year old child, a three year old child, a six year old child, a 5 th percentile female, and a 50 th percentile male.

12. The passenger protection system of claim 11 , wherein the at least one of the audible alert and/or the visible alert and/or the haptic alert originate from at least one door of the vehicle operated by either the driver or another occupant classified as an adult.

13. The passenger protection system of claim 12 , wherein the at least one of the audible alert and/or the visible alert and/or the haptic alert originate from a respective door operated by a last adult exiting the vehicle.

14. The passenger protection system of claim 9 , wherein the additional sensors classifying the driver and the other occupant comprise at least one of an imaging device, a seat belt sensor, a size sensor and a weight sensor.

15. A computer implemented method of preventing trapped passengers in a vehicle, comprising;
tracking vehicle operations with a vehicle control system comprising at least one processor and computerized memory storing vehicle control software therein, wherein the vehicle control software receives input data from a plurality of vehicle sensors;
using a digital control sequence stored in the computerized memory to communicate with an occupant monitoring system comprising at least one sensor, wherein the sensor comprises at least one imaging device identifying a driver and at least one occupant other than the driver in the vehicle;
tracking respective positions of the driver and the at least one other occupant in the vehicle with the occupant monitoring system;
storing the input data in computerized memory, the input data corresponding to the respective positions and vehicle operations;
activating an alert system on a door of the vehicle, the alert system comprising at least one of an audible alert and/or a visible alert and/or haptic alert on the door of the vehicle,
wherein the alert system comprises a haptic switch connected to the door of the vehicle in a position configured to be touched by the driver prior to exiting the vehicle;
using a computer, the input data, and the respective positions to determine that at least one of the driver and/or the occupant is exiting the vehicle;
initiating the digital control sequence to provide the at least one of the audible alert and/or the visible alert and/or the haptic alert on at least one door of the vehicle prior to the exiting.

16. The computer implemented method of claim 15 , further comprising initiating the digital control sequence in an order comprising the visible alert followed by the haptic alert followed by the audible alert, until at least one of the driver and/or the other occupant provide manual feedback acknowledging respective alerts.

17. The computer implemented method of claim 16 , wherein in the absence of the manual feedback, the alert system provides audible warnings and/or visible warnings that are discernible from outside the vehicle.

18. The computer implemented method of claim 15 , further comprising bypassing the haptic switch with a manual trigger configured to receive touch events from the driver.
