Abstract

Restricted operating modes are provided for a motor vehicle when driven by a secondary driver (such as a less experienced driver). A seat occupancy sensor detects the presence of at least one rear seat passenger. A controller includes a memory storing rules defining a restricted operating mode containing a plurality of limitations to be applied to operation of various vehicle accessories in conjunction with the secondary driver. The controller selectively controls the operation of at least one of the accessories according to one of the rules in response to simultaneously detecting the secondary driver and the presence of at least one rear seat passenger. Use of the rules may also depend on whether the rear seat passenger has an unbuckled seat belt.

Claims

1. A system for providing a restricted operating mode of a vehicle, wherein the vehicle includes a driver seat for a driver, rear passenger seats for one or more rear seat passengers, and vehicle accessories for operating in the vehicle, the system comprising:

at least one primary key adapted to be assigned to a primary driver;

at least one secondary key adapted to be assigned to a secondary driver;

a key ignition device positioned on each of the primary key and the secondary key and adapted to generate driver status signals indicative of whether the driver is at least one of the primary driver and the secondary driver;

a seat occupancy sensor for detecting the presence of at least one rear seat passenger; and

a controller operably coupled to the key ignition device and the seat occupancy sensor, wherein the controller includes a memory storing rules defining a restricted operating mode containing a plurality of limitations to be applied to operation of the accessories in conjunction with the secondary driver, the controller being adapted to;

determine whether the driver of the vehicle is at least one of the primary driver and the secondary driver in response to the driver status signals; and

selectively control the operation of at least one of the accessories pursuant to one of the rules in response to simultaneously detecting the secondary driver and the presence of at least one rear seat passenger.

2. The system of claim 1 further comprising a passenger restraint system having an engaged condition for providing crash protection for the at least one rear seat passenger, wherein the controller is further adapted to selectively control the operation of at least one of the accessories pursuant to one of the rules in response to simultaneously detecting the secondary driver and the presence of at least one rear seat passenger without the passenger restraint system being in the engaged condition for the rear seat passenger.

3. The system of claim 2 wherein the controller selectively controls the operation of at least one of the accessories pursuant to a first set of rules when a rear seat passenger is detected and the passenger restraint system is in the engaged condition for the rear seat passenger and a second set of rules when a rear seat passenger is detected and the passenger restraint system is not in the engaged condition for the rear seat passenger.

4. The system of claim 2 wherein the passenger restraint system is adapted to generate a restraint status warning when a rear seat passenger is detected and the passenger restraint system is not in the engaged condition for the rear seat passenger, wherein the controller is capable of allowing the driver to disable the restraint status warning, and wherein one of the rules if comprised of defeating the driver'"'"'s ability to disable the restraint status warning.

5. The system of claim 4 wherein the passenger restraint system comprises a seat belt and wherein the restraint status warning is comprised of a seat belt reminder.

6. The system of claim 4 wherein the vehicle accessories include a mobile phone, and wherein one of the rules is comprised of sending an automated message that the secondary driver and the presence of at least one rear seat passenger without the passenger restraint system being in the engaged condition for the rear seat passenger are simultaneously detected.

7. The system of claim 1 wherein the vehicle accessories include an audio system, and wherein one of the rules is comprised of inhibiting an output from the audio system.

8. The system of claim 1 wherein the vehicle accessories include a mobile phone, and wherein one of the rules is comprised of sending an automated message that the secondary driver and the presence of at least one rear seat passenger are simultaneously detected.

9. The system of claim 1 wherein the vehicle accessories include a transmission control with a park position, and wherein one of the rules is comprised of inhibiting the transmission control from moving out of the park position.

10. A method of providing a restricted operating mode of a vehicle, wherein the vehicle includes a driver seat for a driver, rear passenger seats for one or more rear seat passengers, and vehicle accessories for operating in the vehicle, the method comprising the steps of:

tagging at least one primary key to a primary driver;

tagging at least one secondary key to a secondary driver;

configuring a controller in the vehicle to store rules defining a restricted operating mode containing a plurality of limitations to be applied to operation of the accessories in conjunction with the secondary driver;

initiating operation of the vehicle using the primary key or the secondary key;

generating driver status signals indicative of whether the driver is the primary driver or the secondary driver;

detecting the presence of at least one rear seat passenger;

selectively controlling the operation of at least one of the accessories pursuant to one of the rules in response to simultaneously detecting the secondary driver and the presence of at least one rear seat passenger.

11. The method of claim 10 wherein the vehicle accessories include a passenger restraint system having an engaged condition for providing crash protection for the at least one rear seat passenger, wherein the method further comprises the step of selectively controlling the operation of at least one of the accessories pursuant to one of the rules in response to simultaneously detecting the secondary driver and the presence of at least one rear seat passenger without the passenger restraint system being in the engaged condition for the rear seat passenger.

12. The method of claim 11 further comprising the step of selectively controlling the operation of at least one of the accessories pursuant to a first set of rules when a rear seat passenger is detected and the passenger restraint system is in the engaged condition for the rear seat passenger and a second set of rules when a rear seat passenger is detected and the passenger restraint system is not in the engaged condition for the rear seat passenger.

13. The method of claim 11 wherein the passenger restraint system is adapted to generate a restraint status warning when a rear seat passenger is detected and the passenger restraint system is not in the engaged condition for the rear seat passenger, wherein the controller is capable of allowing the driver to disable the restraint status warning, and wherein one of the rules if comprised of defeating the driver'"'"'s ability to disable the restraint status warning.

14. The method of claim 13 wherein the passenger restraint system comprises a seat belt and wherein the restraint status warning is comprised of a seat belt reminder.

15. The method of claim 13 wherein the vehicle accessories include a mobile phone, and wherein one of the rules is comprised of sending an automated message that the secondary driver and the presence of at least one rear seat passenger without the passenger restraint system being in the engaged condition for the rear seat passenger are simultaneously detected.

16. The method of claim 10 wherein the vehicle accessories include an audio system, and wherein one of the rules is comprised of inhibiting an output from the audio system.

17. The method of claim 10 wherein the vehicle accessories include a mobile phone, and wherein one of the rules is comprised of sending an automated message that the secondary driver and the presence of at least one rear seat passenger are simultaneously detected.

18. The method of claim 10 wherein the vehicle accessories include a transmission control with a park position, and wherein one of the rules is comprised of inhibiting the transmission control from moving out of the park position.
