A vehicle control device aims to ensure more appropriate self-driving based on circumstances around its own vehicle. The vehicle control device controls an engine and a motor such as to drive the vehicle with changing over between motor drive without operation of the engine and hybrid drive with operation of the engine. In the motor drive in a self-driving mode where the vehicle is driven independently of a driver's accelerating or decelerating operation, the vehicle control device maintains the motor drive when an other vehicle condition is not met, where the other vehicle condition is a condition that any other vehicle is present in a predetermined distance at least either ahead of the own vehicle or behind the own vehicle, while allowing for a shift to the hybrid drive when the other vehicle condition is met.

Vehicle control device

When parking is expected at a predetermined point, state of charge reduction control is performed in a current trip to control an engine and a motor, such that the state of charge of a power storage device is lower than the state of charge of the power storage device when parking is not expected at the predetermined point. State of charge recovery control is performed in a next trip to control the engine and the motor, such that the state of charge is recovered during operation of the engine. When parking is expected at the predetermined point but an instruction for motor drive is estimated to be given in a predetermined time period or in a predetermined distance since a start of a next trip that is started at the predetermined point, execution of the state of charge reduction control is limited in the current trip.

Hybrid vehicle and control device mounted thereon

A hybrid vehicle includes an engine, a motor, a power storage device connected to the motor, and an electronic control unit. The electronic control unit executes power storage capacity decreasing control in a current trip and executes power storage capacity recovering control in a next trip when parking at a predetermined point is predicted. The electronic control unit limits execution of the power storage capacity decreasing control in the current trip when heavy-load traveling with a load heavier than a predetermined load is predicted to be performed within a predetermined period after the start of the next trip when the next trip is started at a predetermined point.

When parking is expected at a predetermined point, state of charge reduction control is performed in a current trip to control an engine and a motor, such that the state of charge of a power storage device is lower than the state of charge of the power storage device when parking is not expected at the predetermined point. State of charge recovery control is performed in a next trip to control the engine and motor, such that the state of charge is recovered during operation of the engine. When parking at the predetermined point is expected based on a destination that is estimated by a vehicle exterior system, the state of charge reduction control is performed by a first procedure. When parking at the predetermined point is expected based on a destination that is set by the user, the state of charge reduction control is performed by a second procedure.

A hybrid vehicle including: an engine; a motor; a power storage device; and a control device configured to: i) automatically start and stop the engine; ii) execute, in a current trip, a power storage capacity decreasing control of controlling the engine and the motor such that a power storage capacity of the power storage device in a case where the hybrid vehicle is predicted to be parked at a predetermined point is lower than that in a case where the hybrid vehicle is predicted to not be parked at the predetermined point, and execute, in a next trip, a power storage capacity recovering control; and iii) limit execution of the power storage capacity decreasing control when the hybrid vehicle is predicted to be parked at the predetermined point is predicted and a stopping prohibiting condition for the engine is satisfied.

When parking is expected at a predetermined point, state of charge reduction control is performed in a current trip to control an engine and a motor such that the state of charge of a power storage device when parking is expected at the predetermined point is lower than the state of charge of the power storage device when parking is not expected at the predetermined point. State of charge recovery control is then performed in a next trip to control the engine and the motor such that the state of charge is recovered during operation of the engine. Even when parking is expected at the predetermined point, execution of the state of charge reduction control is restricted in the case where the temperature of the motor is higher than a predetermined temperature.

A hybrid vehicle includes an engine, a motor, a power storage device, and an electronic control unit. The electronic control unit is configured to limit execution of power storage capacity decreasing control and execution of power storage capacity recovering control when a condition a) and a condition b) are both satisfied than when the condition a) and a condition c) are both satisfied, a) is parking at a predetermined point is predicted b) a temperature of the power storage device is out of a predetermined temperature range, and c) the temperature of the power storage device is within the predetermined temperature range.

Hybrid vehicle and controller for hybrid vehicle

An electronic control unit of a hybrid vehicle is configured to determine whether or not parking operation of the hybrid vehicle is being performed. The electronic control unit is configured to control the engine and the rotary electric machine such that starting the engine when the parking operation of the hybrid vehicle is being performed is harder than starting the engine when the parking operation of the hybrid vehicle is not being performed.

Hybrid vehicle and control method of hybrid vehicle

An electronic control unit executes navigation-cooperative SOC control in which traveling situations on a traveling route found through a search performed by a navigation system are predicted and a state-of-charge is controlled by adjusting an output of an engine based on the predicted traveling situations to control charging-discharging of an electricity storage device. The ECU does not execute the navigation-cooperative SOC control when a temperature of the electricity storage device falls below a prescribed temperature and thus charging-discharging of the electricity storage device is limited.

Hybrid vehicle

In a hybrid vehicle including an engine, an electric motor configured to give braking force to the vehicle, a battery configured to exchange electric power with the electric motor, a hydraulic brake configured to give braking force to the vehicle, and an electronic control unit configured to execute regeneration cooperative control such that braking force is given from the engine, the electric motor, and the hydraulic brake to the vehicle based on a driver's brake-on operation, when an open end voltage of the battery is equal to or greater than a first predetermined voltage, the regeneration cooperative control is limited.

A control device for a hybrid vehicle carries out, when a vehicle travels in a downhill control section or a congestion control section, pre-charge/discharge control of changing a target state of charge (SOC) SOCcntr from a standard SOC SOCcntr-n to a specific SOC, and is within a permissible range, in a period in which the vehicle travels from a control start point (Ds) to at least a start point (Dk) of a subject downhill section or a subject congested section. Further, the control device is configured to inhibit, when return control is carried out while the pre-charge/discharge control is being carried out, the pre-charge/discharge control from a start time point (D) of the return control to a time point (D) at which the vehicle has passed through the control section. As a result, fuel efficiency can be improved when the return control is carried out during the pre-charge/discharge control.

The ECU is configured to determine whether a rotation speed of the three-phase AC motor is equal to or less than a predetermined threshold and whether a stopping operation of the vehicle is performed, to determine that the vehicle stops when the rotation speed is equal to or less than the predetermined threshold and the stopping operation is performed, to determine whether the vehicle skids, and to switch a state of the power converter to a state where all on one side of the first and second switching elements are turned off and at least one on the other side of the first and second switching elements is turned on when the ECU determines that the vehicle stops and that the vehicle does not skid.

Control apparatus and control method of vehicle

A vehicle consumes electric power of a battery when traveling in a first mode and sustains a storage power amount of the battery when traveling in a second mode. The travel planning unit forms a travel plan that assigns one of the first mode and the second mode to each zone included in a route. A control unit sets a travel mode of the vehicle to the first mode when the vehicle deviates from the route that is in accordance with the formed travel plan.
