  • Patent number: 10322688
    Abstract: A battery management system (BMS) controls lithium battery access on a utility vehicle. The BMS includes a battery interface that couples with a lithium battery, a load interface that couples with a set of loads of the utility vehicle, and control circuitry coupled with the battery interface and the load interface. The control circuitry mechanically disconnects the battery interface from the load interface in response to a sleep event. Additionally, after the battery interface is mechanically disconnected from the load interface, the control circuitry mechanically reconnects the battery interface to the load interface in response to a wakeup event. Furthermore, after the battery interface is mechanically reconnected to the load interface, the control circuitry maintains connection between the battery interface and the load interface to convey power from the lithium battery to the set of loads of the utility vehicle through the battery interface and the load interface.

  • Patent number: 7239231
    Abstract: In a light control device for a vehicle, a control portion determines whether an illuminance detected by an illuminance sensor reaches a first reference illuminance, and performs a turning on or off control of lights of the vehicle based on the determined result. When the control portion receives an external environment change signal from an environment change detecting means, the control portion uses a second reference illuminance higher than the first reference illuminance, instead of the first reference illuminance, and performs the turning on or off control when the illuminance detected by the illuminance sensor reaches the second reference illuminance. Accordingly, vehicle lights can be suitably turned on or off in accordance with an external environment of the vehicle.

  • Patent number: 7012551
    Abstract: A night vision system for a vehicle includes a first light source for illuminating a region proximate the vehicle, the light source generating a first night vision pulse signal. The system further includes a light sensor receiving a second night vision pulse signal from an approaching vehicle, wherein the second night vision pulse blinds the first night vision pulse signal. A controller shifts pulses from the first night vision pulse signal in a different direction than pulses from the second night vision pulse signal until an anti-blinding of the first night vision pulse signal by the second night vision pulse signal is achieved.

  • Patent number: 6979953
    Abstract: An auto-operated dip switching mechanism includes a strong-light detector, a strong-light signal circuit, and a switching control circuit. The strong-light detector is mounted to a front end of a car to detect light projected from an opposite coming car. The strong-light detector is induced when the light projected thereto has intensity exceeded a preset value, and causes the strong-light signal circuit to produce a strong-light signal, with which the switching control circuit is immediately enabled to switch headlights of the car from high beams to low beams. And, the switching control circuit automatically switches the car from low beams to high beams when the strong-light signal circuit stops sending the strong-light signal.

  • Patent number: 6900594
    Abstract: A method and device for automatically switching on and/or off the illumination of a vehicle. Faulty switching is reduced by adapting the threshold value for switching on the illumination by averaging the measured brightness value(s) according to the driving speed and using switching-off conditions which, inter alia, consider the surrounding brightness.

  • Patent number: 6873110
    Abstract: An HID single light emitting point lamp tube switching device is provided for switching the lamp tube between a far light position and a near light position. Initially, a strong current coil and a weak current coil are induced at the same time, so that the HID single light emitting point are moved to the second position, and at end of a time period set in the timer, the strong current coil will be interrupted so that only the weak current coil is actuated to maintain the HID single light emitting point in the second position.

  • Patent number: 6819051
    Abstract: New electrical circuits for controlling two-color side marker light systems on automotive vehicles are disclosed. There is a different control circuit for vehicles with OEM installed separate amber turn signal lights, OEM installed combination red directional, red brake lights, and OEM installed separate red turn signal lights. These circuits are designed to operate two-color side marker light systems in compliance with NHTSA Federal Motor Vehicle Standard No. 108. The side marker lights normally illuminate amber and turn red with the OEM brake lights. In the turn signal mode, the signaled side alternates between the OEM directional light color and off, while the non-signaled side is amber and will illuminate red with the brake light. A fourth new circuit for emergency vehicles will illuminate the marker lights red with the brake lights, or when switch activated will flash each side independently between two colors.

  • Patent number: 6734634
    Abstract: A control system for daytime running lights (DRLs) is provided that includes a controller for controlling DRLs according to whether the ignition switch is ON and information from the dimmer switch signal of a combination switch, and a plurality of switches that undergo switching according to signals of the controller. Accordingly, if the combination switch is set to activate the DRL system when the ignition switch is ON, a closed loop is formed with both headlights, and the current available to each headlight from the battery is reduced to one half of what it would be if loops were made independently for each of the headlights. When the dimmer switch is selected to high beam, a separate loop is made for each headlight so that a normal amount of current is available to the headlights.

  • Patent number: 6657393
    Abstract: A vehicle lamp has light sources having light emitting diodes that are vertically and horizontally disposed in the form of a square. A first LED group is disposed in the central position of the light source and is turned on in the tail lamp lighting mode. A second LED group surrounds the first LED group, and is turned on together with the first LED group in the stop lamp lighting mode. Thus, the light source appears as if the LEDs became luminous around the central position of the light source in any lamp lighting mode.

  • Patent number: 6566816
    Abstract: A plurality of lamps 21 to 28 inclusive are supplied with a voltage one after another in sequence. A time duration during which the voltage is supplied to each of the lamps 21 to 28 inclusive is controlled in PWM fashion to restrict an amount of voltage supplied thereto. A current detect circuit portion 36 solely detects all of the voltages supplied to the lamps 21 to 28 inclusive, respectively. Each of the voltages exceeds a threshold value, a dead band between two adjacent voltage supply durations. Thus, it is possible to restrict possible electromagnetic noises which are generated upon voltage supply to lamps 21 to 28 inclusive in a vehicular lamp control apparatus in which the lamps 21 to 28 inclusive are supplied with voltage from a high voltage battery 11.
