Vehicle and control method of vehicle
First Claim
1. A vehicle, comprising:
- an internal combustion engine capable of outputting power for driving the vehicle;
a motor constructed to input and output power for driving the vehicle;
an accumulator unit designed to transmit electric power to and from the motor;
a power demand setting module configured to set a power demand required for driving the vehicle; and
a controller programmed to, in a repeatedly run control routine, at a temperature raising time that is a time when the accumulator unit is raised in temperature and a state of charge of the accumulator unit is within a predetermined range, control the internal combustion engine, charging or discharging of the accumulator unit, and the motor so that;
(i) if the set power demand is more than or equal to a first power, then the accumulator unit is discharged;
(ii) if the set power demand is less than a second power which is smaller than the first power, then the accumulator unit is charged;
(iii) if the set power demand is less than the first power and more than or equal to the second power, then the accumulator unit keeps being charged or discharged based on the power demand set in the last execution of the control routine.

Abstract
The charge-discharge power demand is set to the charging power, when the state of charge of the battery is less than the reference value or when the state of charge of the battery is more than or equal to the reference value and less than the reference value while the vehicle power demand is less than reference value. The charge-discharge power demand is set to the discharging power, when the state of charge of the battery is more than or equal to the reference value or when the state of charge of the battery is more than or equal to the reference value and less than the reference value and while the vehicle power demand is more than or equal to the reference value. The charge-discharge power demand is set without change in value to the last set the charge-discharge power demand, when the state of charge of the battery is more than or equal to the reference value and less than the reference value while the vehicle power demand is more than or equal to the reference value and less than the reference value. The engine and the motors are so controlled as the battery is charged or discharged with the charge-discharge power demand and the vehicle is driven with vehicle power demand.
