  • 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.

  • Patent number: 5374877
    Abstract: A travel condition detecting section detects travel conditions of an electric motor car. According to the detected travel conditions, a required output calculating section calculates a required travel output. According to the calculated required travel output, a control commanding section determines travel outputs to be allocated to a plurality of motors coupled to driven wheels of the electric motor car, respectively in such a way that the total power consumption of the motors can be minimized, and further outputs control commands to the motors on the basis of the determined travel outputs allocated to the respective motors.
