Problems solved by technology

[0002] Vehicle customers often purchase all-wheel-drive (AWD) vehicles and four-wheel-drive (4WD) vehicles to better navigate slippery road conditions, but the extra mechanical coupling created when these drive trains are engaged reduces fuel economy
While systems exist for engaging and disengaging AWD and 4WD, these systems require vehicle occupant action to do so
Since people tend to forget, doing this can lead to leaving AWD engaged (which reduces fuel economy), or leaving 4WD engaged (which is undesirable at high speeds)
On the other hand, the driver may forget to engage AWD or 4WD until they experience a loss of vehicle control

Abstract

The present disclosure relates to methods and apparatus for anticipating all-wheel drive engagement and four-wheel drive engagement. A system includes a processor configured to automatically engage all-wheel drive (AWD) when a vehicle reaches an area along a route that is pre-marked as slippery in a memory in communication with the processor. . Said marking may eg have occurred based on the presence of unpaved roads or precipitation in said area.

Description

technical field [0001] The illustrative embodiments relate generally to methods and apparatus for anticipated all-wheel drive engagement and four-wheel drive engagement. Background technique [0002] Vehicle customers often purchase all-wheel drive (AWD) vehicles and four-wheel drive (4WD) vehicles for better driving in slippery road conditions, but the extra mechanical coupling created when these drive mechanisms are engaged reduces fuel economy. While systems exist for engaging and disengaging AWD and 4WD, these systems require action by the vehicle occupant to do so. Since people tend to forget, doing so can result in either AWD being left engaged (which reduces fuel economy), or 4WD being left engaged (which is undesirable at high speeds). On the other hand, the driver may forget to engage AWD or 4WD until he experiences a loss of vehicle control. Contents of the invention [0003] In a first illustrative embodiment, a system includes a processor configured to automa...
