Cruise control can be fitted to most of the vehicles that are on the roads today that have a 12 volt system. Vehicles with a traditional throttle system can have a cruise control with an electric actuator motor and cable. many of the newer Drive-By-Wire (electronic throttle) vehicles can have a solid-state cruise control fitted. Both systems use the same ECU (electronic brain) to control the cruise functions, and both systems use the same range of command modules.
Whether it is an older vehicle, or one of the newest out, with Multiplex/CanBus circuits, the cruise control can often be installed. If the vehicle does not have a speed pulse, then a speed pulse generator can be fitted to give a speed pulse.
Many new models have Multiplex or CanBus wiring, which works like one big computer network around the vehicle. A canbus converter can be installed, to change the computer speed data into a square wave speed pulse, for the cruise control electronic control module to pick up.
Vehicles that are manual transmission will have to have a clutch switch fitted, so that the cruise control cuts out when changing gear.
Cruise control can be fitted to petrol or diesel vehicles. There is one fitted to a speedboat that is used for water ski jump competitions. So that every competitor hits the ski ramp at exactly the same speed.
The cruise control can be over-ridden at any time. Accelerate, if necessary to a higher speed and the vehicle will revert to the set speed when you remove your foot from the accelerator. Use of the brake or clutch pedal will dis-engage the cruise control. Pressing the resume button will re-engage the cruise control at the last setting that was used.
Whilst in cruise mode there is also the ability to 'tap' up, or down. Every time that the 'SET' button is tapped, it will increase your speed by approximately 1kmph. Tapping the 'RES' button will decrease the speed by the same amounts. Holding the 'SET' or 'RES' will accelerate and decelerate the vehicle. Just remove your finger from the button when the desired speed is reached on the speedometer.
Not only will it help you to keep a clean licence, it will lessen the fatigue of driving for long periods. The use of cruise control reduces exhaust emissions, improves fuel economy and gives your right foot a rest into the bargain!
