FIELD: transportation.
SUBSTANCE: device for alerting the EV state in a hybrid vehicle comprises a means for determining the engine rotation speed; a means for determining the EV state; a means for alerting the EV state and part of controlling the switching between the alert and the alert absence of the EV state. The part of controlling the switch switches the means for alerting the EV state in the state of alert absence, when the means for determining the EV state determines that the mode is not the EV state and the engine rotation speed is more than the first threshold value. The part of controlling the switch switches the means for alerting the EV state in the state of alert, when the means for determining the EV state determines that the mode is the EV state and the engine rotation speed is less than or equal to the second threshold value. The first threshold value is less than the second threshold value.
EFFECT: optimising the switching between the alert and the alert absence of the EV state.
