Wed, Apr 7th 2010


Over the years the technology of the aftermarket cruise control has grown significantly, which is due to the advances of the vehicles they need to fit on to. 10 years ago the only aftermarket cruise control systems available were mechanical, and so required inventive solutions dubbed ‘Creative Engineering’ consisting of various brackets and levers in order to fit them.

These days many of the aftermarket cruise control solutions are drive by wire, meaning that they plug into the throttle pedal and the cruise computer mimics the action of your foot at an electrical level. This technology has opened the doors in terms of types of vehicle that are able to have retrofit cruise control installed. Many of the fittings are far simpler, requiring less creative engineering and essentially turning aftermarket cruise control into more of a self-fit or DIY solution.

This product development has inevitably lead to a cost increase however, although the prices are higher, what is gained in the supply has been offset by the improved simplicity in the fitting and the broader range of vehicles which can have aftermarket cruise control fitted. Also, since there are fewer moving parts the hardware is simpler in fault diagnosis, making it more accessible product for the end user.

Most modern cars (year 2000 onwards ish) have, what is termed, drive-by-wire throttle systems. Before the fully electronic cruise control system was developed, the only option was a mechanical system, which works by pulling the pedal down using a bracket. This requires far more room around the throttle pedal in order that the bracket can fit with the required travel to give the cruise control full speed range. Due to this, the new technology has enabled many more small and medium sized cars to be fitted with aftermarket cruise control. Whereas many of the large van and 4x4 ranges can be and still are fitted with mechanical cruise control systems.
