This smart feature utilizes radar and sometimes cameras to monitor traffic conditions, ensuring that our vehicle can respond to the changing speeds of other vehicles on the road without us having to manually adjust the speed. Designed only to maintain a constant preset speed, old-style cruise control lacks intuition and capacity to adjust to changing road conditions. One major concern with cruise control systems relate to the back and forth activity when the driver engages/disengages cruise control. There is some belief that drivers foregoing control of the throttle suffer delays in reaction times when approaching slower traffic or a situation requiring an emergency reaction. While vehicles equipped with electronic stability control can provide aid in case of skilled driver reflexes, many drivers will encounter a dangerous loss in handling trying to compensate for countering cruise control. Employing advanced sensing technology, a new wave of adaptive cruise control systems provide valuable electronic eyes.
Cruise Control in Various Driving Conditions
Star Safety System™ includes Vehicle Stability Control (VSC), Traction Control (TRAC), Anti-lock Brake System (ABS), Electronic Brake-force Distribution (EBD), Brake Assist (BA) and Smart Stop Technology® (SST). Radar-based sensors can be hidden behind plastic fascias; however, the fascias may look different from a vehicle without the feature. For example, Mercedes-Benz packages the radar behind the upper grille in the center and behind a solid plastic panel that has painted slats to simulate the look of the rest of the grille.
Mercedes Distronic Plus
Full-Speed Range is an enhanced version of DRCC that has improved vehicle detection, providing more natural, smoother speed adjustments. Plus, a fourth preset distance setting vs. the three is now standard in this updated system. In stop-and-go traffic, the system demonstrates its agility by handling vehicle-to-vehicle distance control. It can bring us to a complete stop and then resume driving without manual input when traffic begins to move. However, frequent acceleration and braking in congested traffic may result in less predictable behavior from the system and might demand closer attention from us for any manual overrides. The MRCC automatically maintains a safe distance from the vehicle at the front.
Recap of Toyota DRCC
GR Supra’s available Driver Assist and Safety and Technology Packages bring added peace of mind to every drive. The Blind Spot Monitor (BSM) system is designed to help alert you to vehicles that may be in the Supra’s blind spot, letting you know when it’s safe to change lanes. When you’re slowly backing out of a driveway or parking spot, Rear Cross-Traffic Alert (RCTA) provides audible and visual indicators to help warn you of approaching vehicles. Mazda radar cruise control automatically adjusts the vehicle speed in accordance with the car ahead. If the vehicle in the front stops, then the system also stops the vehicle keeping the safe distance from the car ahead.
Perhaps not surprisingly, a stressed-out driver isn’t a very good driver either—a survey of UK drivers found that 71 percent lost concentration at the wheel in the past year due to some form of stress or annoyance. Until recently, adaptive cruise control systems like DRCC have only been available in luxury model cars, but preliminary research indicates that they can be effective. Radar sensors are the eyes of these systems, detecting vehicles in front of us and measuring our distance from them. This technology forms the backbone of both Adaptive Cruise Control (ACC) and Dynamic Radar Cruise Control (DRCC). Furthermore, the system ensures occupants safety by maintaining the set distance with the car ahead.
Know Your Toyota
The first use of cruise control was exercised in 1910 by American auto brand Peerless. While Peerless automobiles are no longer a sight on current highways, cruise control technology has expanded to become an inexpensive luxury feature available on a wide array of new vehicles. Standard cruise control systems were an early form of driving automation. We often recall how they revolutionized driving by allowing us to set a vehicle to maintain a particular speed without constant pedal input. However, these systems had limitations; they couldn’t adjust to the flow of traffic or the actions of other vehicles on the road.

The vehicle can also follow a navigation route set in Mirai’s audio multimedia system. Under certain conditions, like road construction, Advanced Drive is designed to prompt the driver to take full control or will not initialize. Advanced Drive availability also may vary from map depending on HD-map update frequency and accuracy.
VEHICLES
A camera system could notice driver behavior such as brake lights and/or a turn signal. Radar-based ACC is often sold together with a precrash system,[43] which warns the driver and/or provides brake support if there is a high risk of a collision. Also in certain cars, it is incorporated with a lane maintaining system which provides a power steering assist to reduce steering input burden on corners when the cruise control system is activated. ACC technology is regarded as a key component of future generations of intelligent cars. The technology enhances passenger safety and convenience as well as increasing road capacity by maintaining optimal separation between vehicles and reducing driver errors. We can enjoy a more relaxed driving experience on highways and in stop-and-go traffic, as the system accelerates and decelerates smoothly.

Press the driving assist modeselect switch to selectdynamic radar cruise control. When you’re parking, sensors on the front and rear of GR Supra scan for walls, curbs and other objects that might be hidden from your view. Should the system anticipate a collision, it is designed to emit an audible alert, reduce engine output, and automatically apply the brakes.
The system allows the driver to enter one of four preset distances to keep the vehicle cruising at a speed set by the driver above 20 miles per hour. The first adaptive system in 1999, Distronic on Mercedes-Benz vehicles, speed reduction could only result through the ECU throttling back on acceleration. Newer electronic systems now since involved with vehicle braking allows for greater effectiveness to adaptive cruise control. BMW's Active Cruise Control includes a Stop & Go feature which can even draw a vehicle to a complete standstill in cases like gridlock traffic. However, it should be cautioned that braking power exerted by the vehicle's ECU is no more than 20% of total stopping force.
Despite these limitations, adaptive cruise control is a step towards smarter, more autonomous driving technology, making our journeys safer and more enjoyable. Mazda Radar Cruise Control (MRCC) uses a millimeter wave radar to judge the relative speed and distance to the car ahead and automatically controls vehicle speed. Such systems may use a radar, laser sensor or a camera setup allowing the vehicle to brake when it detects the car is approaching another vehicle ahead, then accelerate when traffic allows it to. Toyota Safety Sense is our suite of active safety features designed to support your awareness and decision-making on the road.
Laser-based sensors must be exposed, the sensor (a fairly large black box) is typically found in the lower grille, offset to one side. The vehicle-to-vehicle distance control system allows a driver to use one of three preset distances from the vehicle ahead of the driver if the vehicle is traveling 20 mph or more. Advanced Drive utilizes HD-mapping localization, which allows the system to anticipate the road ahead.
Available Toyota Teammate™ is a suite of advanced driver-assistance technologies featuring Advanced Drive and Advanced Park. Standard on 2023 Mirai Limited, Advanced Park makes parking as simple as pressing a button. Available on 2023 Mirai Limited, Advanced Drive is designed to partner with the driver to promote safe and convenient driving on mapped and limited-access highways.
Can obstruct sensors, leading to decreased functionality or temporary system shutdowns. We should periodically check and clean the sensors to ensure optimal operation.
GR86 models equipped with automatic transmission also come with Rear Parking Sonar with Reverse Automatic Braking. When there is no longer a preceding vehicle driving slower than your vehicle’s set speed, the system accelerates until the set speed is reached and returns to constant speed cruising. When the system determines the road ahead is clear, it will automatically bring your vehicle back to its preset speed. Laser-based systems do not detect and track vehicles in adverse weather conditions nor do they reliably track dirty (and therefore non-reflective) vehicles.
The system uses low-speed following under certain circumstances and intuitive braking to help avoid colliding with preceding vehicles. The automatic braking features help slow down the vehicle as you head into traffic and alert you via the collision warning system controlled by the Toyota Pre-Collision System. Furthermore, the driver can adjust the distance from the car at the front by pressing buttons on the steering wheel. When you change lane or vehicle in the front moves aside, MRCC automatically returns your car to the original cruise speed.
