Abstract:
1. A gear shift control device for a vehicle, comprising: a memory unit that stores a shift map which is defined by a vehicle speed of the vehicle equipped with an internal combustion engine and a load on the internal combustion engine, and in which shift lines are set for each shift pattern of a plurality of gears having mutually different gear ratios of a transmission provided in the vehicle and configured to be capable of shifting the gears; and a control unit that controls the transmission based on shift lines set in the shift map so that shift patterns of the gears are implemented in accordance with an operating state of the vehicle, wherein a first shift line that is used for implementing a shifting pattern for shifting to a highest gear having the smallest gear ratio, and a second shift line that is located at a higher vehicle speed than the first shift line, and that is used for implementing a shift pattern for shifting from the highest gear to a prescribed gear having a gear ratio larger than the highest gear, are respectively set in the shift map, and wherein the second shift line is composed of a first high vehicle speed-high load portion where the vehicle speed is equal to or greater than a first prescribed vehicle speed, and where the load is equal to or greater than a first prescribed load; a first low vehicle speed-low load portion where the vehicle speed is equal to or less than a second prescribed vehicle speed which is below the first prescribed vehicle speed, and where the load is equal to or less than a second prescribed load which is below the first prescribed load; and a first intermediate portion located between the first high vehicle speed-high load portion and the first low vehicle speed-low load portion.
