  • Generating control device for hybrid vehicle
    Patent number: 6215198
    Abstract: A generating control device for a hybrid vehicle includes a motor 13 for driving the hybrid vehicle, a battery 12 for driving the motor, a generator 11 for supplying the motor 13 and the battery 12 with electricity, an engine 10 for driving the generator 11 and a control unit 16. In operation, the unit 16 operates to change the operations of the generator 11 and the engine 10 in both of the normal generating mode and the battery protection mode. Therefore, it is possible to reduce the deterioration of the battery 12 of the hybrid vehicle and to ensure the fine driving performance.

  • Controller for electric vehicle and electric vehicle using the same
    Patent number: 6137250
    Abstract: There is disclosed a controller for an electric vehicle that allows for securing a sufficient battery capacity and is able to substantially avoid giving an uncomfortable feeling to the crew even if an engine for power generation is started. The controller comprises a power generation control unit which makes a generator of the electric vehicle generate electric power by starting a generator-driving engine of the electric vehicle in the case that an SOC (state of charge) of a battery of the electric vehicle is equal to or less than a first value, and further makes the generator generate the electric power by starting the generator-driving engine in the case that the SOC of the battery is equal to or less than a second value larger than the first value and a predetermined condition is satisfied. Further, an electric vehicle provided with such a controller is also disclosed.

  • Method of controlling generator driving engine and system for embodying the same
    Patent number: 5962927
    Abstract: By calculating a fuel vapor quantity in a fuel tank based on a fuel temperature and a fuel residual quantity in the fuel tank, then calculating a fuel vapor purge quantity based on an engine revolution number and engine torque when an engine is driven, and then estimating a fuel vapor quantity captured in a vapor capturing unit based on the fuel vapor quantity and the fuel vapor purge quantity, the engine can be driven to purge the fuel vapor to the engine before the fuel vapor overflows the vapor capturing unit to thus be discharged into the air.
