Hybrid vehicle

摘要

A hybrid vehicle is provided in which after a determination is made as to whether the remaining capacity is higher than a first threshold value, any one of a first running mode, a second running mode, and a third running mode is selected depending on first speed, second speed, or third speed so that the vehicle runs in the mode, whereby the vehicle can run by easily selecting an appropriate series hybrid mode or an appropriate parallel hybrid mode in each range depending on whether the remaining capacity is higher than the first threshold value, and running control can be made stable and easy.

主权项

1. A hybrid vehicle comprising:
an engine mounted on the vehicle; a running-use motor; a battery for supplying electric power to the running-use motor; an electric generator for supplying electric power to the battery; a vehicle speed detecting unit that detects a speed of the vehicle; and a remaining capacity detecting unit that detects a remaining capacity of the battery, the vehicle having:
a first running mode in which the engine is stopped, and the vehicle runs by a drive of the running-use motor;a second running mode in which the electric generator is operated by a drive of the engine, and the vehicle runs by the drive of the running-use motor; anda third running mode in which the vehicle runs by the drive of the engine and the drive of the running-use motor, the vehicle including, a mode selecting unit that selects a running mode so that in a state in which the remaining capacity is equal to or larger than a predetermined first threshold value, the vehicle runs in the first running mode or in the second running mode in a case that the speed detected by the vehicle speed detecting unit is lower than a predetermined first speed, and the vehicle runs in the third running mode in a case that the detected speed is equal to or higher than the predetermined first speed, wherein in a state in which the remaining capacity is less than the predetermined first threshold value, the mode selecting unit selects the third running mode in a case that the speed detected by the vehicle speed detecting unit is equal to or higher than a predetermined second speed that is lower than the predetermined first speed, the mode selecting unit selects the second running mode in a case that the detected speed is lower than the predetermined second speed and is equal to or higher than a predetermined third speed that is further lower than the predetermined second speed and higher than zero (0), and the mode selecting unit selects the first running mode or the second running mode in a case that the detected speed is lower than the predetermined third speed.
