Gear shift map for Automatic Transmission in S mode

Gear shift map for Automatic Transmission in S mode(upshift)

The basic idea of computing the upshift point for Automatic Transmission in S Mode is to find the intersection
of acceleration curve for gear(i) and gear(i+1),
since (delta F)=m*a,in this example,(delta F) is calculated.
