Control system for vehicle

A control system for a vehicle, the control system comprising:

• a driving power source;
• an input rotary member configured to transmit power of the driving power source;
• at least one drive wheel;
• a stepless speed change mechanism provided on a first power transmission pathway, the first power transmission pathway being defined between the driving power source and the drive wheel;
• a power transmission mechanism including at least one gear position, the power transmission mechanism being provided on a second power transmission pathway, the second power transmission pathway being defined between the driving power source and the drive wheel;
• an output rotary member configured to deliver the power to the drive wheel, the stepless speed change mechanism and the power transmission mechanism being provided in parallel on a power transmission pathway between the input rotary member and the output rotary member;
• a clutch mechanism configured to switch the power transmission pathway between the first power transmission pathway and the second power transmission pathway;
• and
• an electronic control unit configured to perform a shift in the stepless speed change mechanism so as to change a rotational speed of the input rotary member in a stepwise manner, according to shift characteristics of a shift performed in the power transmission mechanism, or according to shift characteristics of a shift realized by switching between the first power transmission pathway and the second power transmission pathway,
• the shift characteristics including a shift time required from start of the shift to completion of the shift.
