CU Faculty Develop Vehicle Speed Limiters


Covenant University, Ota, Ogun State, has launched itself into the upper reaches of history with innovative speed limiters developed by two members of its faculty, Professor James Omoleye and Dr. Victor Matthews.

A speed limiter is a device that prevents a vehicle from being driven above a specified speed.

Presenting his invention to the Management of Covenant University on Monday, October 17, 2016, Professor Omoleye, a professor of Chemical Engineering, said his work was prompted by a challenge given in April 2016 by the Nigeria Committee of Vice-Chancellors to Nigerian University Researchers to develop vehicle limiter.

Armed with the objective of developing a speed limiter that can prevent vehicle speed above the set safe speed limit, Professor Omoleye said he has come up with a speed limiter that has the ability to prevent speed beyond the programmed speed limit.

He explained: “By operation, the Speed Limiter gives red light warning to the driver when the programmed speed limit is approached. The driver is expected to either stop acceleration or maintain current speed for safe driving. If the driver, however, continues to accelerate despite the warning light, the speed limiter will start a continuous buzzer sound just about three seconds before the speed limit is exceeded. If the driver stops acceleration at this point and maintain the level of speed, the buzzer continues to sound. If however the driver decelerates, the buzzer sound will stop.

“But if the driver still neglects this buzzer sound warning, as soon as the speed limit is exceeded, this Speed Limiter will slow the vehicle down to a halt and prevent movement for a programmed period of time. After the programmed time of halt, the driver can resume normal operation of the vehicle pending subsequent violation.”

The advantages inherent in the invention, said Professor Omoleye, is the cultivation of a safe driving habit on the driver who actively participates in controlling the speed of the vehicle; and within a short period of using the Speed Limiter, the driver would have developed a subconscious attitude of driving within safe speed limit even if the speed limiter is absent.

Professor Omoleye’s invention was subsequently installed in a car and its effectiveness put to test on the roads within the Covenant University campus. Its operation, as analysed by Professor Omoleye, was validated by the testing crew comprised of the CU Road Safety Chairman, Professor Daniel Gberevbie; Dean, College of Engineering, Professor Christian Bolu; and Deputy Director, Research, Covenant University Centre for Research, Innovation and Discovery (CUCRID), Dr. Obinna Nwinyi.

Dr. Matthews, Head, Department of Electrical and Information Engineering, on his part, has invented a Speed Limiter with special devices which can automatically change the speed of a vehicle wherever it is. The speed limiter, which he said was invented three years ago, has a brain, link to GSM antennae and GPS receiver. “The moment the vehicle wants to move, you can send a speed limit from your phone,” he explained.

According to him, the device is programmed to any limit and has a voice communication in three Nigerian languages, which notifies the driver he is approaching his speed limit about 10 kilometers beforehand. “There would be installation of signposts to alert drivers of speed limit and if it is ignored, it sends a message to the FRSC (Federal Road Safety Corp), and the purpose is to fine you”, Dr. Matthews added.

The Covenant University Vice-Chancellor, Professor AAA. Atayero, who was visibly impressed by the presentations, said the devices will help to stop carnage on Nigerian roads as what is required in traffic is free flow. With the speed limiters, he enthused, everybody becomes law abiding automatically because they cannot go beyond a particular speed limit.
