A vehicle includes: a driving wheel; at least one prime mover; a user interface that receives user's selection of a first traveling mode or a second traveling mode; and processing circuitry configured to control the prime mover in accordance with the selected traveling mode. When a selection disabling condition indicating a predetermined vehicle state is satisfied, the processing circuitry disables selection of the first traveling mode which is performed by the user's selection. When the selection disabling condition is satisfied while the vehicle is traveling in the first traveling mode, the processing circuitry continues the first traveling mode until a switching condition indicating a predetermined vehicle state is satisfied. When the selection disabling condition is satisfied while the vehicle is traveling in the first traveling mode, and the switching condition is satisfied, the processing circuitry switches the traveling mode to the second traveling mode regardless of the user's selection.

Method of controlling vehicle and hybrid vehicle

A hybrid vehicle includes: a driving power source including an engine and an electric motor; a battery that supplies electric power to the electric motor; and a controller that controls the engine and the electric motor according to a temperature of the battery. When a predetermined EV mode condition is satisfied, and a normal-temperature condition in which the temperature of the battery is a threshold or more is satisfied, the controller controls the driving power source in an EV mode in which the electric motor is driven. When the EV mode condition is satisfied, and a low-temperature condition in which the temperature of the battery is less than the threshold is satisfied, the controller operates the electric motor in a state where electric current flows between the battery and the electric motor drives the engine such that the engine generates traveling power transmitted to a driving wheel.

Hybrid vehicle and electric vehicle

A control device of a hybrid vehicle includes: a determiner that determines whether or not a predetermined first condition that efficiency is prioritized is satisfied and whether or not a predetermined second condition that output performance is prioritized; and a control unit that controls an engine and an electric motor in accordance with an accelerator manipulation amount and a determination result of the determiner. When the first condition is satisfied, the control unit controls the driving power source such that the driving power source outputs first driving force in a first driving state where the efficiency is prioritized, and when the second condition is satisfied, the control unit controls the driving power source such that the driving power source outputs second driving force larger than the first driving force in a second driving state where the output performance is prioritized.

Control device of hybrid vehicle, hybrid vehicle, and control method

A vehicle controller for a vehicle including a drive source including an electric motor includes: a sense-of-beating producer configured to acquire a total required torque which is a required torque of the entire vehicle and configured to derive a total target torque corresponding to the total required torque as applied to a predetermined engine combustion cycle; and a target motor torque deriver configured to, based on the total target torque, derive a target motor torque for torque control of the electric motor. The vehicle controller controls the electric motor based on the target motor torque.

Vehicle controller to produce sense of beating via electric motor

A hybrid vehicle controller is configured to: upon receiving a predetermined mode switching request, bring a clutch into a half-clutch state to start an engine using rotation of a transmission shaft; and upon determining that the engine has started, shift the clutch from the half-clutch state to a stand-by state and subsequently shift the clutch to an engaged state, the stand-by state being a state which is intermediate between the half-clutch state and a disengaged state and in which drive power of the engine is not transmitted to the transmission shaft.
