Description
METHOD AND DEVICE FOR INDICATING A CHANGE IN THE STATE OF MOTION
The invention relates to a method and device, such as for example a daytime running light or a brake light, for indicating a change in the state of motion.
PRIOR ART
The prior art discloses a variety of daytime running light devices for indicating a change in the state of motion, such as for example brake lights, wherein the brake light is fixedly mounted on a vehicle, typically on the back and lower part of a vehicle. The brake light is controlled for example with a switch, which is installed in connection with a brake pedal and which lights up the brake light in response to pressing the brake pedal. Similar type conspicuity lights are also direction indicator lights used for indicating a change in the vehicle direction for example to the left and right. The direction indicators are typically controlled manually with a separate switch.
However, the prior art equipment and arrangements involve certain drawbacks. Among other things, the brake lights and direction indicators are commonly installed at such a low height that the conspicuity thereof is poor for example when driving in heavy traffic, rain or snowfall. In addition, when driving for example a snowmobile, the swirling snow raised by the snowmobile with a currently available solution obscures the light at the back. Larger vehicles include also daytime running lights mounted at a higher level. However, this is not possible for example with motorcycles, mopeds, scooters, bicycles, all-terrain vehicles or snowmobiles, from the standpoint of which a good conspicuity would be particularly important because of the small physical size thereof. Moreover, regarding a change of direction, there are many drivers who for some reason choose not to use direction indicators, which is problematic from the standpoint of other road users.
SUMMARY
It is one objective of the invention to eliminate or at least alleviate drawbacks associated with the prior art. According to one embodiment, the invention pursues
to provide such a solution for a conspicuity light, for example a brake or direction indicator light, which would enable a better visibility to be achieved particularly with regard to physically small vehicles. In addition, the invention pursues to introduce a solution, wherein every essential change of direction would be indicated to other traffic regardless of the operator's actions.
Certain objectives of the invention are attained with a device according to claim 1.
The device according to the invention is characterized by what is presented in claim 1 directed to a device. In addition, the driving accessory according to the invention is characterized by what is presented in claim 9 directed to a driving accessory, and the conspicuity system according to the invention is characterized by what is presented in claim 10 directed to a conspicuity system.
In the invention, according to a first embodiment, the device for indicating a change in the state of motion comprises at least one first light emitting element implemented with LED technology, as well as an acceleration sensor adapted to determine acceleration with respect to 1 -3 axes. The device further comprises a control means, for example a microprocessor, which is adapted on the basis of data produced by the acceleration sensor to control said first light emitting element in such a way that, when the acceleration sensor's acceleration is negative in a first direction of the first axis, i.e. for example in braking, the intensity of emitted light is adapted to strengthen. When the question is about a brake light, this is perceived as the brake light lighting up. It should be noted that the brightness of a brake light may change for example as a function of acceleration, such that the higher the braking acceleration the stronger the brake light brightness. There are also other ways of controlling the light, for example by having it blinking at a different frequency as a function of acceleration.
Thereby are achieved major benefits over prior solutions. The device according to the invention can be mounted for example on a helmet or high on the back of a riding suit for a considerably improved conspicuity. The inclusion of an acceleration sensor in the device itself makes the device easy to use regardless of a vehicle. For example, attaching the device to riding gear enables the same riding gear to be used with various vehicles, for example a snowmobile or a motorcycle, nor is it necessary to install the device on every vehicle.
The control means can also be adapted on the basis of data produced by an acceleration sensor to dim the intensity of said first light when the acceleration
sensor's acceleration is positive or substantially zero in a first direction of said first axis. This provides valuable additional information for other traffic regarding for example anticipatory driving.
The device may also further comprise at least second and third light emitting elements for indicating a change in lateral motion (corresponding to direction indicators). In this case, the control means is adapted on the basis of data produced by the acceleration sensor to control said second and/or third light emitting element in such a way that
- when the acceleration sensor's acceleration is positive in a first direction of the second axis, i.e. when turning e.g. to the right, the intensity of a second light is adapted to strengthen, and
- when the acceleration sensor's acceleration is positive in a second direction of the second axis, opposite to the first direction, i.e. when turning e.g. to the left, the intensity of a third light is adapted to strengthen.
The embodiment related to direction indicators provides benefits over the prior art, because, for example in vehicles with no turn signals (i. a. the bicycle), the direction indicators can be implemented with a device of the invention. In addition, according to the invention, the direction light indication turns up regardless of the operator's actions, whereby other traffic is always informed also whenever there is a lateral direction change in the state of motion of the vehicle and thereby the device.
According to one embodiment, for example when the motorcycle is leaning, the acceleration sensor is also leaning. Hence, the acceleration in the range of 0-1 G is generated by gravity along a second axis of the acceleration sensor contingent on the lean angle. The measurement of this acceleration enables a person to conclude which way the cornering is taking place. A directional gyro can also be used in the device. According to these examples, it is also possible to conclude whether for example a motorcycle is being cornered or leaned for example to the left or being returned from a leaning position back to a substantially upright riding position, or whether being leaned in an opposite direction for example for turning to the right.
According to one embodiment, the device may comprise a high pass filter for the elimination of low frequencies, for example slow changes in the state of an acceleration sensor; and/or a low pass filter for the elimination of high frequencies,
for example rapid short-duration changes in the state of an acceleration sensor resulting from vibrations. For example, the rapid fluctuations in acceleration caused by a change in the leaning position can be filtered with a low pass filter.
The device according to the invention, for example in the form of an additional brake light, increases the conspicuity of a vehicle and improves road safety. The device can be placed at a visible location, such as on the back of a motorcycle rider, from where it is clearly visible to other traffic. In addition to a brake light, the system can be provided with direction indicator lights for indicating a change in the direction of a vehicle. Likewise, the increase of speed can also be indicated with a specific light for the purpose. In normal conditions, the brake light can be adjusted for lower brightness, whereby the light functions as an ordinary daylight running light.
The brake light can be made totally independent of a vehicle, because all necessary measurements are obtained from an acceleration sensor included in the device itself. The electric power needed for the device is obtained for example from integrated batteries, making the light useful from bicycle to water scooter and the like without the vehicle requiring extra installations or other modifications.
DESCRIPTION OF THE FIGURES In the next section, preferred embodiments of the invention will be described slightly more precisely with reference to the accompanying figures, in which fig. 1 shows one exemplary device for indicating a change in the state of motion according to one preferred embodiment of the invention, figs. 2A-2B show one exemplary operating principle for the device according to one preferred embodiment of the invention, and shows one exemplary functionality feature for analyzing measurement results and for indicating a change in the state of motion according to one preferred embodiment of the invention.
DETAILED DESCRIPTION OF THE FIGURES
Fig. 1 shows one exemplary device 100 for indicating a change in the state of motion according to one preferred embodiment of the invention, wherein the device comprises an acceleration sensor 101 , a microprocessor 102, a battery 103, a charger and/or charging circuit 104, a LED controller 105, and LED lights or the like light emitting elements 106. The acceleration sensor is used for measuring a change in the speed of the device/vehicle. The sensor is coupled to the microprocessor, which reads the sensor's measurement results as well as subjects the measurements to necessary corrections and filtrations. On the basis of the acceleration measurements, the microprocessor produces light signals for the LED controller.
The LED controller, the microprocessor and other components receive the electric power for themselves from the battery, the charging of which is conducted by using a charging circuit controlling the charger and charging current. The luminous intensity needed for light emitting elements is produced most preferably with energy efficient LED lights. The direction indicator, acceleration and brake lights are nevertheless most preferably provided with specific LED lights. The brightness of these lights is controlled with the LED controller.
The acceleration sensor is most preferably a sensor that measures acceleration in 1 -3 axial directions. The microprocessor is used for implementing a logic needed for reading and analyzing the acceleration sensor. In order to provide a power source for LED lights and peripheral circuits there is required a battery, the charging of which is adapted to be handled by a charging circuit as the charger is connected to voltage. The LED controller comprises for example a transistor and other electronics familiar for a person skilled in the art, and it is adapted to function as a switch and a brightness regulator for the lights. According to one embodiment, the LED lights are implemented with a matrix made up of multiple LEDs.
Figs. 2A-2B illustrate one operating principle 200, 210 for the device 100 according to one preferred embodiment of the invention. As the brake is pressed by the driver, the result is a deceleration 21 1 of the vehicle speed. The microprocessor 02 detects the deceleration with an acceleration sensor 101 and controls a brake light 106, 201. The same principle applies to the detection of lateral accelerations 212, 213 and to the activation of direction indicator lights 106, 202, 203. A forward acceleration 214 of the vehicle is also possible to indicate for example with a specific acceleration light 204.
In normal situation, when the acceleration is zero, the brake light 201 can be employed as a daytime running light. In this case, the LED controller is used for adjusting brightness of the light to a dimmer level. The system can also be supplemented with a sensor measuring the surrounding luminance, whereby the brightness of a daytime running light can be adjusted according to environmental illumination.
Fig. 3 illustrates one exemplary functionality feature 300 for analyzing measurement results and for indicating a change in the state of motion according to one preferred embodiment of the invention, wherein the vertical axis has been used to present an acceleration value measured by the acceleration sensor with respect to some axis, and the horizontal axis to present time.
If the system 100, 200, 210 and the acceleration sensor 101 are mounted for example on a helmet, the driving position and head movements of a rider may develop error in the acceleration sensor's measurement result. Uneven terrain or bumpy road surface also adds undesired noise to the measurement result. These disturbance factors can be eliminated according to the invention for example with a microprocessor 106 by filtering and analyzing the measurement values.
The nuisance factors can be divided roughly in two groups:
- systematic error, e.g. a forward leaning riding position, and
- random error, e.g. movements of the head or bumpiness of the road.
The graph 300 shown in fig. 3 presents typical exemplary cases in terms of analyzing the measurements of an acceleration sensor. A first incident 301 is an accelerating motion with the vehicle speed increasing momentarily. Movements of the head are visible in the graph as calm and minor accelerations 302. Uneven road causes rapid and intense changes 303 in the signal. Braking 304 is quite similar to acceleration but with the opposite sign. The final detail presented is for example a change in the riding position of a driver, which is visible as a systematic error 305.
The impact of systematic errors can be mitigated for example by calibrating the system prior to setting off. When stationary, it is known that the acceleration sensor is only influenced by gravity, the direction of which is downwards. Hence, the acceleration sensor's position can be determined by mathematical calculation and, while driving, the measurement error can be corrected with a microprocessor. If the riding position changes while driving, the correction thereof can be attempted
dynamically for example by working out a longer-term average from the measurement results and by reassessing the acceleration sensor's position on the basis of the averaged measurement.
The elimination of random errors can be carried out with various filters and algorithms. For example, the calm movements of a driver's head can be eradicated from the measurement signal by means of a high pass filter, thus managing to eliminate low frequencies or slow signal changes. The rapid and short-duration disturbances caused by uneven road can be eradicated by means of a low pass filter, thus managing to filter high frequencies or rapid signal spikes out of the measurement results.
Presented above are just a few embodiments for a solution of the invention. The principle according to the invention can naturally be modified within the scope of protection defined in the claims, regarding for example implementation details and fields of use. It is particularly notable that the above-described device or components encompassed thereby can also be distributed for a conspicuity system in such a way that for example the data produced by an acceleration sensor and/or a control means attached to the structural parts of a vehicle is delivered to at least one separate light emitting element wither by way of a cable or wirelessly, whereby said light emitting element can be in attachment for example with the driver's riding gear. Accordingly, the device may also comprise attachment elements for fixing the device to a vehicle and/or riding gear, such as for example to a riding suit or a helmet.
