Abstract
There is disclosed a pedestrian impact sensor, for use with a pedestrian protection system, such as an airbag mounted on the bonnet of a motor vehicle. The impact sensor includes a plurality of sensor devices mounted on the vehicle and discriminates between pedestrian impacts and other impacts by determining whether the input signals from these sensors meet predetermined criteria.
Description
PEDESTRIAN IMPACT PROTECTION SYSTEM
This invention relates to a pedestrian impact sensor for use on a motor vehicle. In particular, the invention relates to a sensor which can be used to detect when a vehicle has suffered an impact with a pedestrian, and discriminate between such impacts and other impacts, in order to activate a mechanism which can protect the pedestrian from the worst consequences of the impact.
When a pedestrian is hit by a motor vehicle, such as a car, the worst injuries suffered by the pedestrian are often not those caused by the initial impact as the bumper (fender) hits the pedestrian's legs but injuries to the pedestrian's head as it hits the bonnet (hood) ofthe vehicle. As a result cushioning mechanisms have been proposed to minimise the injuries suffered by the pedestrian as a result of this latter impact. For example, bonnet-mounted air-bags and flexible or actively sprung bonnets have been proposed.
Clearly, the use of any such cushioning device requires a sensor to be used to detect pedestrian impacts. In particular, because inappropriate deployment of he cushioning device may be a safety hazard in itself, and will in any event cause expense to the vehicle driver, it is essential that a sensor system be provided which can distinguish pedestrian impacts from other impacts with a high degree of confidence.
According to a first aspect ofthe present invention there is provided a control device for a motor vehicle cushioning device, the control device comprising;
means for receiving inputs from a plurality of sensors, located on the motor vehicle and
processing means for comparing the received inputs with stored and calculated reference values and for generating a trigger signal for the cushioning device when the received inputs satisfy predetermined criteria deemed to be indicative of a pedestrian impact.
By using a plurality of sensors the control device can predict pedestrian impacts with a higher degree of confidence. In particular, given that the inputs from a plurality of sensors need to satisfy predetermined criteria before a pedestrian impact is determined to have occurred, it is far less likely that inadvertent or malicious triggering of a safety device could occur.
Preferably, the processing means receives an input signal indicative ofthe vehicle speed and generates the trigger signal for the cushioning device only when the input signal indicates that the vehicle speed falls within a predetermined range. This has the advantage that it will be even more difficult for malicious triggering of a safety device to take place if the trigger signal is only generated while the vehicle is moving.
According to a second aspect of the present invention, there is provided a pedestrian protection system for a motor vehicle comprising;
means for cushioning an impact with a pedestrian, being activatable by a trigger signal.
a plurality of sensors located on the motor vehicle and
a control device for receiving input signals from the sensors and comprising processing means for comparing the received input signals with stored and calculated reference values and for generating a trigger signal for the cushioning device when the received inputs satisfy predetermined criteria deemed to be indicative of a pedestrian impact.
Preferably, the sensors comprise a first impact sensor located in the front bumper or bumper mountings of the vehicle and a second impact sensor located along the front edge ofthe bonnet ofthe vehicle. This arrangement has the advantage that it allows discrimination between impacts with pedestrians and other sorts of impact.
Advantageously, the sensors also include a proximity detector located on the bonnet ofthe vehicle, either centrally or towards the rear windscreen end.
For a better understanding ofthe invention, and to show how it may be put into effect, reference will now be made, by way of example, to the accompanying drawings in which;
Figures la-le represent stages in a collision between a motor vehicle and a pedestrian.
Figure 2 is a schematic illustration of a motor vehicle incorporating a pedestrian protection system in accordance with the invention,
Figure 3 illustrates sensor output waveforms indicative of a pedestrian impact and
Figure 4 illustrates sensor output waveforms obtained from data gathered from a model test vehicle fitted with a pedestrian sensor.
Figure la shows the situation at a first time, a, just before the impact between a moving vehicle 2 and a standing pedestrian 4,
Figure lb shows the moment of impact at time b between the front bumper (fender) 6 of the vehicle 2 and the lower legs 8 ofthe pedestrian 4,
Figure lc shows the position a moment later at time c. as the front part of the bonnet (hood) 10 of the vehicle 2 makes contact with the upper legs or hips 12 of the pedestrian 4,
Figure Id shows the position at a slightly later time d, as the pedestrian 4 falls towards the bonnet 10 ofthe vehicle 2 and
Figure le shows the situation at time e, where an air bag 14 has been activated to cushion the impact of the pedestrian 4 with the intention that injuries to the head and upper torso of the pedestrian should be minimised.
The present invention relates to a system whereby the occurrence of an impact with a pedestrian can be detected and discriminated from other types of impact in sufficient time to allow triggering of the airbag 14 to minimise these injuries. Typically, the airbag will be effective for the period from 5 to 200 milliseconds after triggering and so a trigger signal must be sent at least 5 milliseconds before the expected impact.
Figure 2 shows a motor vehicle provided with a pedestrian protection system in accordance with the invention. The vehicle 2 includes a first impact sensor 22, located in the front bumper, a second impact sensor 24 located at the front ofthe bonnet and a proximity detector 26 located centrally in the bonnet. In the illustrated embodiment, there is a single sensor 22, in the form of (for example) an optical fibre located along the front bumper, and a single sensor 24 in the form of (for example) an optical fibre located along the front of the bonnet. These single sensors could be replaced by groups of sensors if desired. An air bag 28 is located near the rear ofthe bonnet, for deployment over the bonnet, in order to cushion likely impacts ofthe pedestrian. The vehicle has an electronic control device 30 which receives inputs from the sensors 22, 24, 26 as well as a speed indication signal V.
Figure 3 shows the time histories of the three sensor outputs during a typical pedestrian impact sequence. Trace A shows the input from sensor 24, trace B shows the input from sensor 26 and trace C shows the input from sensor 28.
Figure 4 illustrates the time histories of the three sensor outputs for a pedestrian impact sequence, obtained from data recorded from a model test vehicle fitted with a pedestrian sensor. As in Figure 3, trace A shows the input from sensor 24, trace B shows the input from sensor 26 and trace C shows the input from sensor 28.
Thus, the impact sensor on the front bumper first detects an impact at time b and the impact force quickly reaches a maximum before returning relatively slowly to a low level. The strength of the impact is determined by the vehicle speed and the type of impact. If the signal is larger than a speed-related threshold this indicates that the impact is not with a pedestrian. The impact sensor on the front of the bonnet of the vehicle first detects an impact at time c and the impact force reaches a higher level before again falling back down to a low level.
Typically, the sensor 24 detects a larger impact force than the sensor 22 because the hip presents greater inertia than the jointed legs ofthe pedestrian. Typically, the output from sensor 24 is larger than the output from the sensor 22 by a factor of between 2 and 8. The various time intervals depend on the vehicle speed.
For example, if the horizontal distance from the front edge of the bumper to the front edge ofthe bonnet is ∑, (for example, 0.1 metres), the horizontal distance from the front edge of the bumper to the rear edge of the bonnet is y (for example, 1 metre) and the vehicle is travelling at speed y (for example 30 mph, or 13.4 m s' ). the interval from time b to time c may be very close to x v (approximately 7.5 ms in this example). The interval from time b to time e may be somewhat greater than y/y (which is approximately 75 ms in this example).
Trace C shows how the signal from the proximity sensor 26 increases as the pedestrian falls towards the bonnet 10. For convenience, this signal is monitored at the time when the vehicle is expected to have moved half the distance from the front edge ofthe bumper to the rear edge of the bonnet. It is expected that at this time the signal will have reached a significant level and be increasing.
As mentioned above, the control device 30 also receives a signal V indicative ofthe vehicle speed.
The control device compares various features ofthe received sensor signals, for example the magnitudes ofthe impacts and the time interval between the impacts, and sends a trigger signal to activate the airbag 28 when these meet specified criteria.
In the preferred embodiment ofthe invention, a trigger signal is sent to the air bag 28 only when the sensor inputs satisfy four specified criteria, namely :-
(i) The signal V indicates that the vehicle is travelling at a speed within a particular range, for example 5-40 mph (8-64 kph).
(ii) The impact on sensor 22 does not exceed a threshold which is calculated on the basis ofthe measured vehicle speed y and a predetermined constant.
(iii) The impact on sensor 22 is followed by an impact on sensor 24 which is greater in strength by a factor in the range from 2-8 and which follows at a time interval which is sufficiently close to the expected time delay y/y.
(iv) At a time (y 12) . y, the output from sensor 26 shows a significant and increasing signal level.
Of course, these criteria are only exemplary. Other criteria could be added and the airbag could be triggered when only some of the specified criteria are met.
There is thus disclosed an arrangement which allows reliable sensing of pedestrian impacts to trigger an airbag to minimise the effects of those impacts.
