When is it not safe to use cruise control?

When is it not safe to use cruise control?

When you SHOULDN’T use cruise control Don’t use cruise control when it’s raining, snowing, or when there are wet/ icy roads in general. While some newer vehicles have features that help your car handle wet roads and rain even while cruise is on, it’s best to be in total control of your car when you are driving in these conditions.

How does a good cruise control system work?

A good cruise control system accelerates aggressively to the desired speed without overshooting, and then maintains that speed with little deviation no matter how much weight is in the car, or how steep the hill you drive up. Controlling the speed of a car is a classic application of control system theory.

Why is cruise control more common in American cars?

­Cruise control is far more common on American cars than European cars, because the roads in America are generally bigger and straighter, and destinations are farther apart.

What does it mean to have adaptive cruise control?

Modern “adaptive” systems (see below) include the ability to automatically reduce speed when the distance to a car in front, or the speed limit, decreases. This is an advantage for those driving in unfamiliar areas.

When is the best time to use cruise control?

Use cruise control when there is little to no traffic. Cruise control lets you enjoy those clear roads and helps you maintain a consistent speed. Speaking of speed, use cruise control only when the speed limit stays the same for long periods of time. Just be sure to turn it off and slow down when the speed changes, so you don’t get a ticket.

What does cruise control do in a car?

Cruise control is the capability of setting a vehicles speed and allowing it to continue maintaining that speed indefinitely. The mechanics behind cruise control systems have evolved over the years, but all are based on that core function.

When to forgo cruise control on a trailer?

Other places to forgo the comfort of cruise control include icy or otherwise slick roads, and in heavy traffic. We’ve found some bridge decks set up an awful “bounce” for our truck and trailer combination that’s enough to rattle your teeth out. Drop off the speed control and slow down to get these nasty bounces under control.

When to use cruise control on a hill?

Cruise on hills can be a different story. We’ve found by our own experience that leaving the cruise control engaged when hill climbing is OK when the grade isn’t real steep. On steeper grades the cruise will try and maintain speed, downshifting, and eating more fuel.
