  • Patent number: 11358477
    Abstract: A magnitude of a road surface slope along which a vehicle travels is detected, when the magnitude of the road surface slope increases, a basic braking force set in advance is corrected to be decreased based on the magnitude of the road surface slope, or a basic driving force set in advance is corrected to be increased based on the magnitude of the road surface slope, when the magnitude of the road surface slope decreases, a basic braking force is corrected to be increased based on the magnitude of the road surface slope or a basic driving force is corrected to be decreased based on the magnitude of the road surface slope, and the corrected braking force or driving force is generated.
    Type: Grant

  • Patent number: 9315147
    Abstract: A brake light control device that generates a braking force, and is used with a brake device which can control the braking force according to a signal from a brake control unit regardless of the operation of a brake operator includes: a brake light switch that is inserted and arranged into an electrical connection path between a power supply and a brake light, and is opened and closed together with the operation of the brake operator; and a switching switch that is opened and closed in response to braking force control. The brake light control device further includes: a blinking switch that is connected in parallel to the switching switch; and a control unit that, when the brake light is required to be blinked, is configured to keep the switching switch in an OFF state, and blinks the brake light by repeatedly switching on and off the blinking switch.
