Abstract
The invention provides a method of progressive engagement of all-wheel drive for a mobile vehicle. A set of vehicle parameters is sensed, and an all-wheel drive lock value is determined based on the sensed set of vehicle parameters. Vehicle subsystem control activation is determined, and the all-wheel drive lock value is adjusted based on the vehicle subsystem control activation determination. An all-wheel drive controller is engaged based on the adjusted all-wheel drive lock value.
Claims21
A method of progressive engagement of all-wheel drive for a mobile vehicle, comprising:
- sensing a set of vehicle parameters;
- determining an all-wheel drive lock value based on the sensed set of vehicle parameters;
- determining vehicle subsystem control activation;
- adjusting the all-wheel drive lock value based on the vehicle subsystem control activation determination;
- engaging an all-wheel drive controller based on the adjusted all-wheel drive lock value;
- and
- controlling at least one differential based on the adjusted all-wheel drive lock value.
A computer usable medium including a program for progressive engagement of all-wheel drive, comprising:
- computer program code to determine an all-wheel drive lock value based on the sensed set of vehicle parameters;
- computer program code to determine vehicle subsystem control activation;
- computer program code to adjust the all-wheel drive lock value based on the vehicle subsystem control activation determination;
- and
- computer program code to engage an all-wheel drive controller based on the adjusted all-wheel drive lock value;
- computer program code to control at least one differential based on the adjusted all-wheel drive lock value.
A system for progressive engagement of all-wheel drive, comprising:
- means for sensing a set of vehicle parameters;
- means for determining an all-wheel drive lock value based on the sensed set of vehicle parameters;
- means for determining vehicle subsystem control activation;
- means for adjusting the all-wheel drive lock value based on the vehicle subsystem control activation determination;
- means for engaging an all-wheel drive controller based on the adjusted all-wheel drive lock value, and
- means for controlling at least one differential based on the adjusted all-wheel drive lock value.
