The Adaptive Cruise Control system maintains a set speed while automatically adjusting the vehicle’s speed to maintain a safe following distance from the car ahead. The low-speed follow function extends ACC capabilities to stop-and-go traffic, allowing the TLX to come to a complete stop and resume movement without driver intervention.

  • How it works: Using a forward-facing radar sensor, ACC monitors the distance and speed of vehicles ahead and adjusts throttle and braking accordingly.
  • Benefits: Reduces driver fatigue during highway driving and congested traffic conditions.

2. Collision Mitigation Braking System (CMBS)

CMBS uses radar and camera inputs to detect potential frontal collisions. If the system determines that a collision is imminent, it provides visual and audio warnings to alert the driver. If the driver does not respond, CMBS can automatically apply the brakes to reduce the severity of a collision or avoid it altogether.

  • How it works: Combines data from the front camera and radar to assess collision risk and intervene when necessary.
  • Benefits: Helps prevent or mitigate accidents by providing timely alerts and automatic braking.

3. Lane Keeping Assist System (LKAS)

Lane Keeping Assist helps the driver stay centered in their lane on highways and well-marked roads. The system provides gentle steering inputs if it detects inadvertent lane departure without the turn signal engaged.

  • How it works: Uses a front-facing camera to detect lane markings and monitors the vehicle’s position within the lane.
  • Benefits: Enhances safety by reducing the risk of unintended lane departures and potential collisions.

4. Road Departure Mitigation System (RDM)

RDM alerts the driver and takes corrective action if the vehicle begins to drift off the road unintentionally. It uses lane departure data combined with road edge detection to determine when the car is leaving the road and applies braking and steering assistance to keep the vehicle on the roadway.

  • How it works: Monitors lane markings and road edges via the front camera and intervenes if necessary.
  • Benefits: Prevents accidents caused by veering off the road, especially on winding or rural roads.

5. Blind Spot Information (BSI) System with Cross Traffic Monitor

BSI warns the driver of vehicles detected in adjacent lanes, particularly in the blind spot areas, using radar sensors mounted on the rear corners of the vehicle. The Cross Traffic Monitor assists when reversing by detecting approaching vehicles from either side and alerting the driver.

  • How it works: Rear-mounted radar sensors monitor adjacent lanes and the area behind the vehicle.
  • Benefits: Enhances situational awareness during lane changes and reversing maneuvers.

6. Traffic Sign Recognition System

This feature uses the front-facing camera to identify traffic signs such as speed limits, stop signs, and no-entry signs, displaying them on the instrument panel. It assists drivers by keeping them informed of important road signs they might otherwise miss.

7. Auto High-Beam Headlights

The Auto High-Beam system automatically switches between high and low beams depending on surrounding traffic conditions and lighting, improving nighttime visibility without dazzling other drivers.

How AcuraWatch Works: Sensors and Cameras

The effectiveness of AcuraWatch depends on a network of sensors and cameras strategically placed around the vehicle:

  • Radar Sensors: Located in the front grille and rear corners, radar sensors detect the speed and distance of nearby vehicles and objects, even in poor visibility conditions such as fog or heavy rain.
  • Monocular Camera: Mounted behind the windshield near the rearview mirror, it detects lane markings, traffic signs, and obstacles.
  • Ultrasonic Sensors: Used primarily for parking assistance and blind spot monitoring, providing close-range object detection.

These components work together to provide AcuraWatch with a 360-degree awareness of the vehicle’s surroundings, enabling real-time analysis and intervention.
