HYBRID SYSTEM 37
FP201. NOTE
. When the charge level of the high voltage battery is high, EV driving is used. However the engine may start automatically at times of high load or when driving at high speed.
. When the charge level of the high voltage battery is low, both the engine and electric motor are used for driving. However if the charge level recovers as a result of regenerative braking or other charging, EV driving can be used again.
CONTROL WHEN DRIVING IN EACH MODE shsaa03
Driving using only the electric motor shsaa0301
The EV driving range will vary in accordance with conditions such as vehicle speed, the amount of charge remaining in the high voltage battery and the usage of the climate control system. In order to drive only on the electric motor power for a long time, observe the following.
. Avoid sudden acceleration, sudden deceleration and be sure to drive smoothly. If you repeatedly accelerate, the high voltage battery charge will deplete quickly. Also, EV driving may be canceled by rapid acceleration or high vehicle speed.
. Restrain your speed as much as possible. The distance that can be driven in driving using only the electric motor will reduce considerably at high speeds.
NOTE
. EV driving range
– The EV driving range changes in accordance with the charge status of the high voltage battery and the
speed of the vehicle. – Even if there is enough charge
remaining in the high voltage battery, EV driving may be canceled and both the gasoline engine and the electric motor are used depending on the situation.
. Even if there is a sufficient amount of electricity remaining in the high voltage battery, EV driving may be canceled and both the gasoline engine and the electric motor are used depending on the situation. EV driving will be returned automatically after EV driving becomes possible again. EV driving may be canceled automatically in the following circumstances:
– Power is needed temporarily, for example when the accelerator pedal is depressed firmly or when
accelerating suddenly. – The temperature of the hybrid
system is high because the vehicle has been left in the sun, driven on a
hill, driven at high speeds, etc. – The temperature of the hybrid
system is low. – The climate control system is in
operation. – The defroster button is pressed. – The system determines that the
gasoline engine needs to be started. The gasoline engine may also operate in circumstances other than those listed above, depending on conditions.
Driving using both the electric motor and engine shsaa0302
In driving using both the electric motor and engine, controls are primarily carried out as follows in accordance with the driving conditions.
. The gasoline engine stops when the vehicle is stopped.*
. During start off, the electric motor( traction motor) drives the vehicle.
. During hybrid system driving, the gasoline engine and electric motor( traction motor) are controlled effectively, and the vehicle is driven with optimum fuel efficiency. Also, when
