What is the Difference Between Cruise Control and Speed Limiter?
2 Answers
Speed limiter and cruise control are very similar. The biggest difference is that after setting the speed limit, if you want to maintain the set speed, your foot cannot leave the accelerator pedal. Once the set speed is reached, the computer will automatically determine the required fuel supply at that time. Unless the accelerator is pressed down quickly and deeply, slight increases in the accelerator will have no effect. Cruise control system, also known as automatic cruise control system, functions to maintain the vehicle's speed as required by the driver without the need to press the accelerator pedal, allowing the vehicle to travel at a fixed speed. In contrast, the speed limiter ensures that the vehicle travels within the speed range set by the driver, preventing the vehicle from exceeding the speed limit. Content Extension: 1. Cruise Control: Cruise control is the most common. The basic control method is to activate the cruise mode, select the set speed, and then release the accelerator to maintain the current speed. During driving, the speed can be adjusted via control buttons (lever). To cancel the cruise setting, simply press the brake or turn off the cruise switch. The biggest feature: completely freeing both feet, allowing hands to control the direction while also adjusting the accelerator. 2. Speed Limiter: The speed limiter is very similar to cruise control. The biggest difference is that after setting the speed limit, if you want to maintain the set speed, your foot cannot leave the accelerator pedal. Once the set speed is reached, the computer will automatically determine the required fuel supply at that time. Unless the accelerator is pressed down quickly and deeply, slight increases in the accelerator will have no effect. The accelerator becomes a safeguard for the speed limiter switch; only by pressing the accelerator can the same effect as cruise control be achieved. The biggest feature: the foot does not leave the pedal, allowing for shorter reaction time in emergency situations; since the accelerator remains controllable, on roads with many ups and downs, it is much more humanized than lower-level 'artificial intelligence'.
On long drives, I love using cruise control the most. Set it to 110 km/h and release the throttle, and the car maintains speed automatically whether going uphill or downhill without slowing down, giving my foot a nice break. The speed limiter is completely different—set an upper limit like 120 km/h while pressing the throttle, and it cuts fuel if you exceed it to alert you, but your foot must stay on the pedal. It’s great for preventing speeding in the city. Once on a nighttime highway drive, my cruise control suddenly disengaged; later, I learned a road bump triggered the brake sensor. Most cars today come with both features—just different button placements—and using them right really saves hassle and fuel.
