Abstract

A driving instruction aid comprises a line 4 connectable by screw adjusters 5 and 6 to a clutch pedal 2 and an accelerator pedal 3. The line 4 is reeved in a cover 7 over fixed pulleys 8 and 10 and a jockey pulley 9 mounted on a tension arm 11. The line 4 ensures that the accelerator pedal 3 is lifted when the clutch is disengaged by pushing pedal 2, thereby avoiding overrevving of a declutched engine, and allowing a driver under instruction to get the “feel of” correct pedal control movements.

Description

SPECIFICATION
Driving instruction aid
This invention relates to a driving instruction aid for aiding pupil drivers to learn coordination of clutch and the accelerator pedals during driving instruction, and to protect the instruction vehicle from the effects of enept manipulation of the controls.
In learning to drive a car, it is necessary to learn the “feel” of the control pedals and to come to be able to control the clutch and accelerator pedals so that power is applied smoothly as the clutch is engaged-insufficent power provided by the throttle will cause the engine to stall, while snatch in application of the pedals will cause jerky motion in the vehicle.
The pupil must acquire the “feel” of a correct pedal action so that a smooth engagement of the clutch after a gear change can be effected, and when this has been acquired, the operation still needs to be practiced until it can be carried out automatically without conscious control.
An object of the invention is to provide a device which can be applied to the control pedals of a car to ensure that the correct proportional movements of the pedals are carried out by a pupil driver so that he can learn the “feel” of the correct movements, and eventually be able to carry them out without the assistance of the device.
Since repeated over-revving, stalling and jerking can damage the car, the device also serves to protect the car from much wear during the initial stages of instruction. Where a car is used constantly for this purpose its iife can be considerably increased.
In accordance with this invention, the device comprises a non-extensible line, secured at one end to a car’s accelerator pedal, and at the other to the clutch pedal, the line being reeved on fixed pulleys and a resiliently mounted moveable pulley for maintaining the tension of the line.
The device is preferably mounted in a box or casing ever the pedals in a non obstructive position.
The length of the line can be adjustable to obtain the desired tension, for fitting to various models of car, and also to provide a desired degree of lost motion between the pedals. The device will ordinarily be adjusted to allow the correct throttle setting for engagement of the clutch for operation on the level.
It may be adjusted for down hill or up hill starting, yet it may also be assumed that when instruction has reached that stage the driver under instruction has acquired the basic feel of the control pedals.
A preferred embodiment of the invention will
now be described by way of example with reference to the accompanying drawings, wherein: Fig. 1 is a diagrammatic illustration of the device at rest,
Fig. 2 shows the device when the clutch pedal is fully depressed;
Fig. 3 shows the device when the clutch pedal is being slowly released, and
Fig. 4 when the clutch pedal is fully released and the accelerator pedal fully depressed.
In the drawings, I denotes a box guarding the device. The box 1 is mounted above a clutch pedal 2 and an accelerator pedal 3 of the car. The pedals are interconnected by a line A having a wire strand line 4 attached to each pedal by means of a respective screw-adjustor 5.6 and a coiled wire cover sheath 7. Each screw adjustor has a block shaped body with a threaded bore receptive of a threaded shaft for adjustment in the effective length of line 4 whose end is attached to a knurled end of the shaft. The length and tension of the cable 4 can be adjusted by screwing either of the shafts into or out of its body.
The cable 4 is reeved over fixed pulleys 10 and 8, and a moveable pulley 9 carried on a pivotable tension arm 11 tensioned bya tension spring 12. In
Fig. no pressure is applied to either pedal, and the arm 10 is interposed, both pedals are supported by the line 4. In Fig. 2 pressure is applied to the clutch pedal 2, and line 4 pulls the accelerator pedal up to the “throttle closed” position. The clutch is disengaged and the engine idling. In Fig. 3, the clutch pedal 2 is being eased up, whilst the release of the line allows the accelerator pedal to be depressed by an equivalent amount, gradually opening the throttle.Finally in
Fig. 4, the clutch pedal has been released, so that the clutch is “biting” fully, and the accelerator pedal can be depressed fully to allow the car to pull away, or accelerate up to the optimum speed for the new gear.
The device operates by restricting the amount by which the accelerator can be depressed as the clutch is released, so that over-revving is avoided while the engine is declutched. Over-application of the accelerator provides an urging upwards of the clutch pedal so that the driver senses pressure on his clutch pedal foot, while under acceleration, and thus stalling is discouraged. The pupil driver should by use of the device gain experience of the feel and relative foot movements involved’in the correct co-ordination of clutch and accelerator.
The device will also enable gear changing and level starting readily to be carried out while instructor and pupil are concentrating on other aspects of driving.
The cable 4 by means of the screw adjustor 5 and 6 may be readily disconnectable from the pedals 2 and 3 so that the car can be used by pupils who have learned the coordination and for use in driving tests, when the Examiner is able to ascertain from dual control clutch pedal operation that the device does not then effect the accelerator control so as to give the driver under instruction any unusual advantage. A toggle or like adjustor, not shown, may be provided accurately for effecting predetermined variation in the amount 6f most motion, for example by moving one or both of the fixed pulleys in line of varying adjustors 5 or 6, for avoiding physical disconnection during driving test, and/or for facilitating hill starting.

Claims (5)

1. A driving instruction aid comprising a nonextensible line securable at one end to a car’s accelerator pedal, and at the other end to the clutch pedal, the line being reeved on pulleys and having a resiliently mounted tensioning device permitting predetermined independant relative movement of said ends of the line.

2. A driving instruction aid according to claim 1, wherein the line is connected at least one end via a screw adjuster whereby the effective length and tension of the line is adjustable.

3. A driving instruction aid according to claims 1 or 2 wherein the line is connected at each end to a screw adjustor, releasable securable to the respective control pedal.

4. A driving instruction aid according to claims 1, 2 or 3 wherein a moveable pulley is mounted on a pivoted tension arm connected to a tension spring.

5. A driving instruction aid substantially as hereinbefore described with reference to and as illustrated in the accompanying drawings.
