Abstract

A bank of lights (20) mounted across the rear window of a vehicle are progressively illuminated from opposite ends towards the centre, or vice versa, according to the amount of deceleration of the vehicle during braking. Deceleration may be sensed by a group of inertia switches (21-26), for example. An enable signal (32) from the vehicles braking circuit ensures that the lights only operate during braking, and the lights are latched to remain on during any single braking period.

Description

VEHICLE BRAKING INDICATOR
TECHNICAL FIELD OF THE INVENTION
This invention relates to an indicator which is installed in a vehicle to indicate to other road users that the driver of the vehicle is braking.
BACKGROUND
In recent years high level rear brake lights have become commonplace in new vehicles. When the driver brakes the brake lights, which are normally red, are illuminated to prove an advance warning to other road users that the vehicle in front has braked. Following drivers should then take appropriate action to slow their own vehicles and thus prevent a possible collision.
Whilst high level brake lights increase rear visibility compared with conventional low level brake lights mounted on opposite sides of the vehicle they do not provide other drivers with an indication of the extent to which the vehicle is braking. In other words, if the driver lightly touches the brakes the visible signal is the same as when the driver brakes hard. This can be a major problem when driving in a stream of traffic on a motorway for example since drivers may be continuously touching their brakes to regulate their speed. If the traffic suddenly comes to a halt the drivers behind have no indication that the queue is stopping and rear shunts are therefore very common.
Previous proposals for solving this problem include brake pedal sensors for detecting the amount of movement or pressure applied to the brake pedal. The sensors can be used to control warning lights which are intended indicate the extent to which the vehicle has been braked. However, this is highly dependent on the characteristics of the particular vehicle. For example, if a vehicle carries a heavy load it requires heavier braking than when it is lightly loaded. Also, the pedal travel can change as the braking system ages.
The present invention seeks to provide a new and inventive form of vehicle braking indicator which is more accurate and reliable than known devices.
SUMMARY OF THE INVENTION
The present invention provides a vehicle braking indicator having a bank of light sources for mounting in a position such that they are visible to other road users, and deceleration sensing means which is arranged to provide an output which varies with deceleration of the vehicle to progressively increase the number of illuminated light sources with increasing deceleration.
The deceleration sensing means may, for example, incorporate a plurality of inertia sensors arranged at incremental angles. Alternatively, a movably mounted proof mass may be provided with capacitive or other movement sensing means.
The deceleration sensing means is preferably arranged to operate one or more of said light sources in a latching manner such that the device or devices remain illuminated.
The indicator preferably receives an enabling signal from the vehicle braking system so that the bank of light sources can only operate during braking. Furthermore, the latching arrangement is preferably reset to extinguish the light sources when the brakes are no longer applied.
The light sources may be mounted in a row in known manner and arranged to progressively illuminate from opposite ends towards the middle of the row, or from the middle outwards.
BRIEF DESCRIPTION OF THE DRAWINGS
The following description and the accompanying drawings referred to therein are included by way of non-limiting example in order to illustrate how the invention may be put into practice. In the drawings:
Figure 1 is a general view of an electromechanical vehicle braking indicator in accordance with the invention; and
Figure 2 is a view of solid state version of the vehicle braking indicator. DETAILED DESCRIPTION OF THE DRAWINGS
Referring firstly to Fig. 1 , an electromechanical braking indicator is shown, which includes a bank of twelve red filament lamps 20 numbered 1 to 12 from left to right. The number of lamps could of course vary. Also, other light sources could be used such as high intensity light-emitting diodes. The lamps are connected together in six pairs from the outside towards the centre of the row. Thus, lamps 1 and 12 are connected together, lamps 2 and 11 , lamps 3 and 10 etc. The lamps may be mounted in a row along an elongate housing 20 for installation across the rear window of a motor vehicle for example.
The braking indicator also incorporates six inertia switches 21 to 26, one for each pair of lamps. A preferred form of switch incorporates a proof mass such as a ball bearing or globule of mercury which bridges a pair of contacts when the mass moves under inertia, although other forms of inertia switch may be used. The switches are preferably mounted inside the housing 20 at progressively inclined angles, typically at 3° increments, relative to the front-rear axis of the vehicle. The angles of the switches are indicated in the drawing by the angular scale 30. Thus, as the vehicle decelerates the number of switches which are actuated will vary depending on the deceleration level.
The indicator has a power input connection 32 which is connected to the brake light circuit of the vehicle. This is typically fed by a switch coupled to the brake pedal to provide +12v whenever the brake pedal is depressed. The earth return of the housing is connected to the chassis of the vehicle in the conventional manner. The supply voltage is fed via a protection fuse 33 to one contact of each of the inertia switches 21-26. The second contact of each inertia switch is connected to a respective pair of lamps. For example, the first inertia switch 21 which is inclined at the shallowest angle is connected to the two outermost lamps 1 and 12 as shown. The switch also supplies a respective 12 volt relay 34 which is connected for latching operation. When the relay coil is energised by the inertia switch 21 the relay contacts will close and bypass the inertia switch so that the relay remains energised and the lamps remain illuminated. For convenience of illustration only one relay is shown in the drawings, but it will be appreciated that each inertia switch is arranged to operate the respective pair of lamps in similar manner so that the lamps progressively light from the outside towards the centre, depending on the overall deceleration level.
Braking of the vehicle will cause the vehicle to decelerate depending on the severity of braking. Hard braking will produce maximum deceleration so that the number of lamps which are illuminated will directly depend on the extent to which the brakes are applied. Once the lamps are illuminated they will remain on due to the action of the latching relays until the brake pedal is fully released to remove the 12v supply from the input 32, allowing the relays to reset. The use of the latching relays ensures that the lamps remain on to indicate the maximum tilt of the vehicle during any single application of the brakes. The relays also remove any contact bounce effects within the inertia switches which might cause the lamps to flicker.
Progressive illumination from the ends of the row towards the centre has the advantage that the display is likely to be visible to drivers further back in a queue who may only see part of the display. Alternatively however, the first inertia switch 21 which is inclined at the shallowest angle, and its associated latching relay 34, may be connected to one or more lamps at the centre of the display. Each inertia switch is arranged to operate a respective pair of lamps so that the lamps progressively light from the centre outwards, depending on the overall deceleration level. This arrangement gives the following driver the impression that the vehicle is getting closer as the deceleration level increases.
Visibility may also be increased if the lamps are arranged to flash during any period of operation, e.g. by incorporation of a bimetallic strip in series with the lamp. A flash rate of between 2 and 7 flashes per second gives the best effect.
In most cases between 4 and 26 light sources will provide the desired braking indication. The angular increments between the inertia switches is inversely proportional to the number of light sources.
Fig. 2 shows an electronic version of the indicator. The indicator includes a bank 40 of red high intensity lamps or light-emitting diodes, mounted in a row, which are driven from respective outputs of a micro-controller MPU via respective semiconductor switches (not shown). Two or more of the light sources could be connected together for operation from a single MPU output if desired. A decelerometer is provided by a proof mass 42 which is suspended by resilient elements 43 between a pair of capacitive electrodes 44, 45 forming a differential capacitor system which changes its capacitance as the mass body undergoes deceleration. The output signal from the electrodes 44 and 45 is amplified by a differential amplifier 46 which supplies a digital signal to the MPU via an analogue-to-digital converter 47. By using a suitable mapping algorithm the MPU can calculate the deceleration level from the differential output signal and illuminate the light sources of the indicator bank 40 progressively from opposite ends towards the centre according to the level of deceleration. The MPU receives an enabling signal from the braking circuit of the vehicle via input 32 so that the bank is only illuminated during braking. The MPU software latches the illuminated light sources until the brakes are released.
The bank of light sources and the decelerometer may be mounted in a housing with the lights extending across the rear window of the vehicle.
Progressive illumination from the ends of the row towards the centre ensures best visibility for drivers further back in a queue. However, the light sources may alternatively be connected to progressively light from the centre outwards, depending on the overall deceleration level, to give the following driver the impression that the vehicle is getting closer. Visibility may also be increased if the light sources are arranged to flash during any period of operation, e.g. by using flashing LEDs or generating a pulsed signal in the MPU. A flash rate of between 2 and 7 flashes per second is preferred.
With the braking indicators described the light sources will not operate during acceleration of the vehicle because, although the deceleration sensor may be triggered, the brakes are not normally operated during acceleration.
It will be appreciated that the features disclosed herein may be present in any feasible combination. Whilst the above description lays emphasis on those areas which, in combination, are believed to be new, protection is claimed for any inventive combination of the features disclosed herein.
