Abstract:
A method for controlling gearshifts of an automatic transmission includes preventing an upshift while the vehicle accelerates on an ascending grade, if predicted vehicle acceleration in a target gear is less than a reference vehicle acceleration in the target gear; accelerating the vehicle on the grade; and producing the upshift, if predicted vehicle acceleration in the target gear is greater than a reference vehicle acceleration.
