Problems solved by technology

[0003] However, even if the hybrid vehicle runs on electric power from a place closer to the parking place, depending on the driving state from the nearest place to the parking place, there is a possibility that upon reaching the parking place , the charge rate of the battery is not efficiently reduced to the target charge rate

[0034] First, the first embodiment will be described. like figure 1 As shown, the hybrid vehicle 10 is equipped with: an engine 12; a battery (a lithium ion secondary battery (battery)) 16 that can be charged with electric power (electrical energy) generated by driving the engine 12; The electric power charged to the battery 16 drives; the battery control unit 18 controls the rate of charge (State of Charge: hereinafter sometimes referred to as “SOC”) of the battery 16 by controlling the engine 12 and the motor 14; The vehicle control device 20 of the device.

[0035] That is, the hybrid vehicle 10 can run while appropriately switching between the two driving forces of the engine 12 and the motor 14 . Furthermore, as described above, the engine 12 is driven not only for traveling but also for charging the battery 16 . In addition, the battery 16 can also be charged by the regeneration of the motor 14.

[0036] The vehicle control device 20 includes a first control device 2...

[0078] Next, the second embodiment will be described. In this second embodiment, as Figure 7 As shown, the approach condition to the parking spot includes a distance correction value β set based on data when the hybrid vehicle 10 has parked to the parking spot in the past. Specifically, first, similarly to the first embodiment, the analysis unit 30 predicts the parking time of each candidate location, and predicts the candidate location expected to be long-term parking as the destination (step S21 ).

[0079] Then, the predicting unit 32 predicts the travel route based on the via point and the destination, and sets the point P2 at a point closer to the destination by a predetermined distance α. After the point P2 is set, the position detection unit 42 periodically detects the current position of the hybrid vehicle 10, and the analysis unit 30 determines whether the hybrid vehicle 10 has reached the point P2 (step S22).

[0080] After the analyzing unit 30 determines that th...

Abstract

The invention relates to a vehicle control device, a vehicle control system, and a hybrid vehicle. A control device for a hybrid vehicle is provided with: a prediction unit that acquires position information of a parking point that is predicted to have a parking time exceeding a threshold value on a travel path of the hybrid vehicle; and a target setting unit that sets a target charging rate of the battery, and, when the hybrid vehicle satisfies a condition for approaching the parking place, changes the target charging rate setting to a second charging rate lower than the first charging rate during normal time, and controls the amount of charge. When the target setting unit sets the target charge rate to the second charge rate, the charge / discharge amount of the battery corresponding to the second charge rate becomes larger toward the discharge side than the charge / discharge amount of the battery corresponding to the second charge rate during normal time.

Description

technical field [0001] The present invention relates to a vehicle control device, a vehicle control system, and a hybrid vehicle. Background technique [0002] In a hybrid vehicle in which the battery can be charged by the electromotive force generated by the engine, a vehicle control device is known that determines that the vehicle is proceeding to a parking spot where the estimated parking time is longer than a predetermined time during running with the engine. When moving, the target charging rate of the battery is lowered, and the battery is charged by running with electric power from a point closer to the parking point by a predetermined distance (for example, see Japanese Patent Laid-Open No. 2017-081416). [0003] However, even if the hybrid vehicle travels by electric power from a point closer to the parking spot, depending on the driving state from the immediate point to the parking spot, there is a possibility that when the parking spot is reached , the charge rat...
