SE524698C2 - Testing method for reaction time of vehicle driver, by applying controlled braking or acceleration force to vehicle wheels - Google Patents

Abstract

A controlled braking or acceleration force is applied to at least one of the vehicle wheels. The braking or acceleration force causes the moving vehicle to sway and/or deviate from its course and the reaction time of the driver needed to correct this swaying or deviation is tested. An independent claim is also included for the reaction time testing device.

Description

o o | q us 524 698 2 evasive maneuver and / or in case of slippery road conditions, the mental presence and an achieved driver skills are of crucial importance for this to take place. During the training, training in incident situations should therefore take place. A training in control and handling of vehicles in varying situations is facilitated by the present invention applied to training vehicles. A check of the achieved motor handling skills is also important as a basis for quality assurance of a driver training.

Because the invention allows a small transverse turn to occur by applying a short braking pulse to one of the front wheels, which turn is in no way adventurous for road safety when used in traffic, the sensitivity and presence of the driver and his sense of balance can checked. This is done in such a way that you record the time that elapses from the time the pulse is applied until the reaction takes place. The way of reacting (the force and magnitude of the corrective steering angle) is also checked and possibly compared. with previously stored reaction patterns for the current driver.

When training on a practice track, the braking pulse on one or more of the wheels can be stronger and even so large that the vehicle stands on its side unless a fast and correct corrective maneuver is performed by the driver. Of course, these exercises must continue with gradually increasing difficulty and be completely adapted to the practicing driver and his ability and achieved level of skill.

These exercises can also mean that alternating pulses are applied to both wheels (on both sides) to induce and / or possibly. reinforce the development of cables and return cables and allow training in the lifting of these.

One would think that modern anti-slip and anti-skid technology would reduce the requirement for the driver's skill level when it comes to handling his vehicle. Actually, it is the opposite. To be able to take full advantage of a cord-inhibiting technique, where 'AÅ', g.

The result of a survey is used to determine: a) the driver's attention / sensory presence. Requires a comparison with the norm. b) the driver's achieved level of learning. Requires study of the development of the measured values over time. (c) the dynamic characteristics of the vehicle.

Through what has previously been proposed in our other patent applications - with power pulse on the steering wheel (with or without a corresponding steering wheel on the front wheel) - the present invention will be able to form the basis for an extension of the different types of pulses that give vehicle reactions which in turn act on different senses. In addition to the power pulse on the steering wheel, there is the possibility of a gear pulse on the vehicle that affects both the sense of sight and the sense of balance (where the sense of balance is included). An effect on pressure-sensitive receptors on the back and end of a driver can also be achieved. For some drivers, it is the sensitivity in the back and end area that is the first to react when possible. loss of grip, while other drivers have their visual sense reacting only in such a situation. Through our invention, 524,698 4 Ang. P.ans no. It is possible to identify which senses are the dominant and / or most sensitive when driving a vehicle.

With knowledge of this, different measures can be taken for different drivers to maintain a high aurosal effect (sensory presence) when driving the vehicle.
