Filed: 2017-05-09
Abstract: PROBLEM TO BE SOLVED: To provide a control device of a vehicle capable of performing S&S control during traveling to suppress automatic restart of an engine during vehicle stop in the S&S control during stopping while satisfying cooling request.SOLUTION: A stop duration time ti in next vehicle stop is predicted (ST4) when an automatic stop condition is established during traveling (YES in ST2). An evaporator temperature Ta not automatically restarting an engine during the predicted stop duration time ti, is calculated (ST5). A time t necessary for the evaporator temperature to reach Ta is calculated (ST6), when a coasting travel is started. In a case when the time t is more than a stop requirement time ts to the next vehicle stop, the coasting travel is executed (ST8). Thus a probability of automatic restart of the engine in the vehicle stop condition is reduced, and fuel consumption rate can be improved.SELECTED DRAWING: Figure 4
