Then, take your foot off the brake, and the vehicle will hold its position. Once traffic moves, press the Resume button and the vehicle will automatically accelerate to your set speed or following gap if a vehicle is detected ahead. On select newer Toyota vehicles, the full-speed range automatic cruise control is featured instead. This version provides the same function but for travelling at a wider speed range of zero to 180 km. You are more likely to see these features on vehicles with Toyota Safety Sense 2.0 or 2.5. In a proportional control system, the cruise control adjusts the throttle proportional to the error, the error being the difference between the desired speed and the actual speed.
Keeping the Driver Engaged
Cruise control is not a substitute for a human driver and will require supervision at every step. If you are using a semi-autonomous system, you will not need to steer but will need to keep at least one hand on the wheel for safety measures. Accelerate to your desired speed as you prepare to activate cruise control.
Leveling up AI: how close are we to self-driving cars?
Not until Mercedes-Benz developed its Distronic cruise control did cruise control with self-braking make its first public appearance. Simple to use, all you need to do is turn on the system in your vehicle, reach your desired cruising speed, and set it. The system then assumes control of the accelerator, maintaining the set speed until the driver engages the brake.

So, using cruise control is most fuel-efficient on level highways and long uphill and downhill grades. For example, some cars have a combined button to set the initial speed and accelerate. Others have fine-tuning buttons that you can click to increase or decrease your speed by a set amount, often one mph.
That can be dangerous when you’re traveling behind another slowing vehicle.” She recommends reading the automaker’s website closely and learning about the speed ranges before using ACC while on your test drive. On the latest vehicles fitted with electronic throttle control, cruise control can be integrated into the vehicle's engine management system. Modern "adaptive" systems include the ability to automatically reduce speed when the distance to a car in front, or the speed limit, decreases.
Check your car’s controls
Once you set a distance, the ACC adjusts your speed to ensure you stay at that distance — usually a car length or two. Cruise control is a feature on some vehicles that allows the driver to take their foot off the accelerator while the onboard computer maintains the vehicle’s speed. Within cruise control, you can typically also adjust your speed up and down using buttons. Toyota Safety Sense P (TSS-P) is an adaptive cruise control system that, like most Toyota safety technologies, uses GPS and radar to detect traffic ahead of you. This feature is usually found on vehicles with Toyota Safety System P (TSS-P). Just as with traditional cruise control, the adaptive cruise control system requires drivers to choose their preferred speed.

This week’s wheels
For instance, it can allow drivers to relax their grip and even periodically let go of the steering wheel, while the car maintains a safe distance from other vehicles when driving on a straight, boring section of highway or when stuck in a traffic jam. ADA systems can also have safety benefits, such as potentially keeping you from crossing over a lane line into opposing traffic during a moment of inattention. By monitoring other vehicles and objects on the road, adaptive cruise control enables a safe and comfortable driving experience. It does so by helping the driver keep a steady vehicle speed at a given moment. The driver can set their preference regarding certain factors, such as the distance to the car in front, driving mode – for example, economical, sporty or comfortable – and others. Together with information about speed limits, road curvature, accidents data and more, these choices influence the automatically selected speed.
In the picture above, you can see two cables connected to a pivot that moves the throttle valve. One cable comes from the accelerator pedal, and one from the actuator. Yes, many modern Adaptive Cruise Control systems come with stop-and-go technology that can bring your vehicle to a complete stop and then resume driving when traffic starts moving again.
Active Driving Assistance Systems in Action
With a unique combination of radar sensors, cameras and location technology, it helps cars maintain a safe distance from the one it is following behind, significantly reducing the possibility of rear-end collisions. These features are usually activated using a button on the steering wheel with the image of a car next to a speedometer with an arrow pointing at it. A conventional cruise control system does not automatically keep a set distance away from the car in front, and it is indicated by a similar logo without the car next to the speedometer. A tip to know if your car has adaptive cruise control or regular cruise control is to look for the “gap distance” button, which usually shows a symbol of a car with horizontal distance bars in front. This button will determine how much space your car leaves between its front bumper and the rear of the car it is following. Maybe not, but automatic cruise control technologies bring your car a step closer to being fully automatic.
For this category, we judged how well each system’s lane centering assistance (LCA) kept the vehicle in the center of the lane, as well as how smoothly and intuitively the adaptive cruise control (ACC) could adjust its speed behind other cars. Adaptive cruise control or Active Cruise Control (ACC) is an advanced driver assistance system (ADAS) that automatically adjusts a vehicle’s speed when there are slow-moving vehicles ahead, with the aim of maintaining a safe following distance. When the road ahead is clear, ACC automatically accelerates to your pre-set speed. Adaptive Cruise Control is an advanced driver assistance feature that automatically adjusts your vehicle’s speed to maintain a safe distance from the vehicle in front. Unlike traditional cruise control that maintains a constant speed, ACC can speed up or slow down based on the flow of traffic. While it’s a step up in terms of driving automation, for safety, a human driver is still required to supervise constantly, including steering, braking, or accelerating.
Vehicles with autonomous cruise control are considered a Level 1 autonomous car, as defined by SAE International.[2] When combined with another driver assist feature such as lane centering, the vehicle is considered a Level 2 autonomous car. To use cruise control, you can typically press buttons on your steering wheel to activate the system, set your speed, adjust your speed up or down within the system, and deactivate the system. Using cruise control lets you set a speed for your car to maintain even if you take your foot off the gas. Cruise control can also prevent speeding and increase fuel efficiency by limiting unnecessary acceleration and braking.
If the system detects that the driver isn’t looking forward for 4 to 5 seconds, an audible warning alerts him or her to watch the road. “It’s disappointing that both Lucid and Nissan have this equipment in their vehicles, yet they aren’t using it to the fullest, safest potential,” Funkhouser says. Please check your Owner’s Manual for more information about features. Automotive engineers tweaked around the edges of cruise control for the next 35 years. However, cruise control didn’t evolve much beyond the first system that found its way into the 1958 Chrysler Imperial. The system worked seamlessly and I could see using it on occasion.
