  • Patent number: 9024469
    Abstract: A vehicle has a low-voltage power generator driven by an engine, a standard low-voltage battery and a standard low-voltage electric load. Additional equipment has an additional low-voltage battery for supplying electric power to an additional low-voltage electric load. The additional low-voltage battery is charged with electric power from the low-voltage power generator. The additional equipment further has a high-voltage battery for supplying electric power to a high-voltage electric load, and a converter for converting low-voltage electric power from the low-voltage power generator to high-voltage electric power. When relays are opened during a period in which engine operation is stopped, the electric power is supplied from the additional low-voltage battery to the converter, so that the high-voltage electric power is supplied to the high-voltage electric load, such as a motor-driven compressor.

  • Patent number: 8965658
    Abstract: A vehicle controller includes a wheel speed sensor, a skid sensor, an upper limit calculator, and a motive power controller. The wheel speed sensor is configured to detect rotational speed of driving wheels. The skid sensor is configured to determine whether or not the driving wheels are skidding based on an output of the wheel speed sensor. The upper limit calculator is configured to calculate an upper limit of rotational speed of the driving wheels if the skid sensor determines that the driving wheels are skidding. The motive power controller is configured to control motive power output from the driving source so that rotational speed of the driving wheels is equal to or smaller than the upper limit calculated by the upper limit calculator.
