Methods and systems for vehicle safety lighting are disclosed, including a system having a multi-axis accelerometer that detects acceleration of the vehicle along a first axis and a second axis normal to the first axis, and outputs a corresponding first axis acceleration measurement and a second axis acceleration measurement. A controller is coupled to the multi-axis accelerometer, and to an array of light emitter elements (LELs). The controller is configured to determine a vehicle deceleration, based at least in part on a combination of the first axis acceleration measurement and second axis acceleration measurement, and to detect the vehicle deceleration exceeding a brake light threshold and, based at least in part on the detection, output a deceleration light signal to the array of LELs. Digital filtering prevents operation of the safety lighting by accelerometer outputs unrelated to axial deceleration, such as will occur upon encountering a hill, or, in the case of a motorcycle or the like, leaning into a turn.

Disclosed is a system for providing vehicle indicator lights, such as brake lights for a bicycle or motorcycle. The system may include at least one indicator light, a gyroscopic sensor, an accelerometer, a power supply, and a signal processing unit that receives inputs from the gyroscopic sensor and the accelerometer and activates an indicator light based on inputs from the sensors. Various algorithmic functions and other features may also be included in the system to make detection more robust and the make the system useable for a variety of different vehicle applications.

A powered skateboard having a powered wheel. The performance of the powered wheel can be modified based on one or more signals from one or more sensors on the powered vehicle and/or on a user of the powered vehicle.

When an automatic transmission shift start condition is satisfied, an electronic control unit calculates a meter target rotational speed of an engine by adding a correction amount corresponding to the state of a torque converter to a turbine rotational speed corresponding to a post-shift gear stage, and makes a meter display rotational speed follow after the meter target rotational speed, fixes the correction amount to a value obtained at the time of shift start determination, when immobilization conditions including that the shift start condition for a downshift is satisfied and that the engine is driven are satisfied. When actual rotational speed display conditions are satisfied, it can be predicted that differences between an engine rotational speed and a turbine rotational speed before and after shifting are large, and so the electronic control unit sets a current engine rotational speed as the meter target rotational speed or ends the control.

A variable accelerator light assembly. The variable accelerator light assembly includes a light bar having light elements spanning between a first end and an opposing second end. A sensor connected to a vehicle accelerator pedal of a vehicle detects how much a user depresses the vehicle accelerator pedal, and transmits this information to the light bar. The light elements energize sequentially from a middle portion outward to the opposing first and second end. The progressive actuation of the vehicle accelerator pedal causes an increasing number of the light elements to energize in the sequential configuration.

Embodiments of the present invention can provide an accessory control system, a light control system, and/or a brake light control system for golf carts and/or other vehicles, including trailers, motorized vehicles, and non-motorized vehicles. Embodiments relate to a control system that can be easily installed on a golf cart and/or other vehicles. Specific embodiments relate to a light system that has few is any wires connecting the light system to, or interfering with, any existing electrical circuitry of the gold cart. Specific embodiments can be installed on any golf cart, such as in the same location(s) as prior light systems. Embodiments of the subject light system can be rear tail lights, rear braking lights, front running lights, and/or front headlights.

A visual deceleration indication apparatus signals to pedestrians and other vehicles that a vehicle is slowing down or coming to a stop. Illuminating devices, such as LEDs, contained in a license plate frame located in the front of the car, are activated when the vehicle decelerates. An accelerometer or other sensory device is used to detect deceleration and sends a signal to illuminate the LEDs, thereby letting others know that the vehicle is slowing down. The license plate frame may be connected directly to a rear brake light component without the use of accelerometers or other sensors. When the brake is applied, the LEDs in the license plate frame are illuminated. The LEDs may be contained in other forms and located in different positions on the front or side of the car.

A brake lamp module for a vehicle, wherein the module includes a housing, lamp device, sensor, and electronic control unit (ECU). The lamp device, sensor and ECU are carried by the housing. The ECU is configured based at least in part on data received from the sensor to provide a power signal that causes illumination of the lamp device. In at least some embodiments, this arrangement permits actuation of the brake lamp or other lamp device in response to detection of a hazard event, such as rapid deceleration of the vehicle. And, in at least some embodiments, this may be done independently of actuation of the brake pedal by the driver.

A system for implementing strobing of existing vehicle hazard lights including an interface to a vehicle wiring harness configured to receive input to an existing vehicle flasher module, a strobing circuit that responds to an activation signal from the vehicle wiring harness that is indicative of a hazard flasher deployment event by producing an electrical output having a strobing pattern that is perceptibly faster than a cycle of existing vehicle signal lights, and an OR circuit having two inputs, one of which accepts the electrical output from the strobing circuit and another of which intercepts output to an existing auxiliary vehicle lamp that is not otherwise activated with existing vehicle flashers or signal lights.

The helmet further comprises a luminous sensing unit, a tilt calculator unit, and an analyzer unit. The luminous sensing unit measures outdoor lighting conditions and provides a feedback signal to the control unit. The tilt calculator unit configured to calculate a tilt angle between axes of a vehicle to a surface and sends one or more data on the tilt angle to the control unit. The analyzer unit configured to process one or more neuron behaviors of a user, and provides the one or more neural activities to the control unit. The control unit generates an output signal via the one or more display.
