What's the difference between that and adaptive cruise control? On my 16 RAV4H it can be set at 40 kmh and above. Newer Toyota's will have stop and go feature.
Here are descriptions of normal cruise control, adjustable speed limiter and adaptive cruise control.
Normal cruise control sets a
minimum speed. The driver can accelerate past the set speed, but cannot decelerate below the set speed without cancelling or turning off the cruise control.
Adjustable speed limiter is the opposite of normal cruise control; it sets a maximum,
do not exceed speed. The driver can decelerate below the set speed but cannot accelerate above the set speed without cancelling or turning off the speed limiter. The maximum speed may be set manually by the driver or automatically by the car reading road-side speed limit signs.
A factory-set speed limiter is already available on high-end vehicles, not allowing the high-powered vehicle to exceed some preset (high) limit.
Adaptive cruise control sets a minimum speed and the maximum speed is set by traffic conditions. Adaptive cruise control allows the driver to automatically follow the traffic directly ahead at a set distance and the latest ones allow start-and-stop ability without having to cancel or reset the cruise control function. With no traffic in front, the car will cruise along at the set minimum speed (as with normal cruise control).
Adjustable speed limiter and adaptive cruise control are necessary steps toward autonomous driving, with speed limits set automatically by reading road-side signs, fully digital maps in the navigation system or vehicle-to-infrastructure communications.
I have long thought that an adjustable speed limiter would be a nice feature to have. It would allow me, while driving on a wide-open highway, to set a maximum speed to save fuel, reduce wear on the engine and reduce the risk of being caught speeding.
