A motor vehicle includes: an engine; an electric motor for traveling that is able to perform regenerative driving; a power storage device that is able to supply electric power to the electric motor and to be supplied with electric power from the electric motor; and a control device that controls autonomous driving including automated parking. Interruption control of causing a vehicle to stop and setting a shift position in a neutral range to interrupt autonomous driving is executed when a shift operation is performed during autonomous driving. The shift position is set in a parking range and autonomous driving is ended, and then the power storage device is charged using power from the engine, when a storage ratio of the power storage device reaches less than a predetermined ratio during interruption of autonomous driving that is performed through the interruption control.

A controller for a hybrid electric vehicle including an internal combustion engine is provided. The internal combustion engine includes a filter arranged in an exhaust passage collect particulate matter from exhaust gas. The controller executes a first deceleration control process, a second deceleration control process, and a selection process. The first deceleration control process uses a fuel cutoff process when deceleration of the hybrid electric vehicle is required. The second deceleration control process does not use the fuel cutoff process when deceleration of the hybrid electric vehicle is required. The selection process selects execution of the second deceleration control process when a PM deposition amount is greater than or equal to a threshold value and selects execution of the first deceleration control process when the PM deposition amount is less than the threshold value.

A control system for a hybrid vehicle configured to suppress a temperature rise in a transmission while achieving a required driving force without modifying a cooling system. If a temperature in the transmission is lower than a threshold level during propulsion in a hybrid mode, a controller operates an engine at an optimally fuel efficient point. If the temperature in the transmission system is equal to or higher than the threshold level during propulsion in a hybrid mode, the controller shifts the operating point of the engine to the point at which the heat generation in the transmission system can be suppressed.

Disclosed are a hybrid vehicle torque adjusting method and device. The method includes: acquiring a requested torque of a front-axle engine and a requested torque of a rear-axle motor, determining a first compensation torque according to the filtered requested torque of the front-axle engine and an actual output torque of a front-axle transmission, and determining a target torque of the rear-axle motor according to the first compensation torque and the requested torque of the rear-axle motor. In the method, since a difference exists between the filtered requested torque of the front-axle engine and the actual output torque of the front-axle transmission during shifting of the front-axle transmission, after the difference is compensated by the rear-axle motor, a working condition that affects a dynamic performance of an entire vehicle can be eliminated, torques can be coordinated, and the dynamic performance of the entire vehicle can be improved.
