Discover how these innovative systems work and the significant advantages they bring to both your work and your customers’ driving experience.

 

1. What is Active Cornering Enhancement?

Active cornering enhancement refers to a suite of sophisticated automotive technologies designed to improve a vehicle’s handling and stability during cornering. Unlike traditional passive suspension systems with fixed settings, active systems dynamically adjust various parameters in real-time to optimize grip, reduce body roll, and enhance driver confidence. These systems utilize sensors, electronic control units (ECUs), and actuators to proactively manage the vehicle’s behavior based on driving conditions and driver inputs. Think of it as a smart, responsive chassis that adapts instantly to the demands of the road, providing a more secure and engaging driving experience.

2. How Does Active Cornering Enhancement Work?

The magic behind active cornering enhancement lies in its intricate network of sensors and actuators working in concert. Here’s a breakdown of the typical components and their functions:

• Sensors: These collect crucial data about the vehicle’s state and the driving environment. Common sensors include:
  • Wheel speed sensors: Measure the rotational speed of each wheel.
  • Steering angle sensors: Detect the angle of the steering wheel.
  • Yaw rate sensors: Measure the vehicle’s rotation around its vertical axis.
  • Lateral acceleration sensors: Detect the sideways force acting on the vehicle.
  • Roll rate sensors: Measure the vehicle’s tilting motion from side to side.
  • Suspension travel sensors: Monitor the compression and extension of the shock absorbers.
• Electronic Control Unit (ECU): This is the brain of the system. It receives data from the sensors, processes it using complex algorithms, and determines the necessary adjustments to optimize cornering performance. The ECU communicates with various actuators to implement these adjustments.
• Actuators: These components execute the commands from the ECU. Examples include:
  • Active anti-roll bars: Electromechanical or hydraulic systems that can vary the stiffness of the anti-roll bars to reduce body roll during cornering while allowing more independent wheel movement on uneven surfaces. According to a study by Continental AG, active roll control systems can reduce body roll by up to 80% (Continental AG, “Active Roll Control,” Technical White Paper).
  • Adaptive dampers: Electronically controlled shock absorbers that can adjust their damping force in real-time to provide optimal ride comfort and handling. Bilstein, a leading manufacturer, states that their adaptive damping systems can react to changing road conditions within milliseconds (Bilstein, “DampTronic® X”).
  • Torque vectoring differentials: These differentials can actively distribute torque between the rear wheels to improve cornering agility and reduce understeer. GKN Automotive highlights the effectiveness of their torque vectoring technology in enhancing vehicle dynamics (GKN Automotive, “Torque Vectoring”).
  • Active rear steering: Systems that can steer the rear wheels by a small angle, either in the same direction as the front wheels at higher speeds for stability or in the opposite direction at lower speeds for increased maneuverability. ZF, a major automotive supplier, details the benefits of active rear axle steering in improving both agility and stability (ZF, “Active Kinematics Control”).

The system works dynamically. For instance, as a driver enters a corner, the sensors detect increased lateral acceleration and yaw rate. The ECU analyzes this information and might instruct the active anti-roll bars to stiffen, the adaptive dampers to firm up, and the torque vectoring differential to send more power to the outer rear wheel, effectively helping the vehicle turn more precisely and with less body lean.

3. Benefits of Active Cornering Enhancement

Implementing and servicing vehicles equipped with active cornering enhancement systems offers numerous benefits for both your garage and your clientele:

• Enhanced Handling and Stability: Customers will experience improved vehicle responsiveness, reduced understeer and oversteer, and greater control during cornering, leading to a safer and more enjoyable driving experience. This translates to higher customer satisfaction and repeat business for your shop.
• Increased Tire Grip: By actively managing weight transfer and suspension behavior, these systems help maintain optimal contact between the tires and the road surface, maximizing grip and reducing the likelihood of skidding. This is a significant safety advantage that you can highlight to your customers.
• Improved Ride Comfort: While enhancing handling, many active systems also improve ride comfort on uneven roads by allowing more independent wheel movement when not cornering aggressively. Adaptive dampers, in particular, play a crucial role in this balance.
• Greater Driver Confidence: The predictable and controlled handling provided by active cornering enhancement systems instills greater confidence in drivers, especially in challenging driving conditions. This is a key selling point for these technologies.
• New Service and Diagnostic Opportunities: As more vehicles are equipped with these advanced systems, your garage will have new opportunities for diagnostics, maintenance, and repair. Investing in the right tools and training, such as those offered through VCCarTool, will position your business as a leader in servicing modern vehicles.

4. Cars with Active Cornering Enhancement

Active cornering enhancement technologies are increasingly found in a wide range of vehicles, from luxury sedans and SUVs to high-performance sports cars. Here are some examples of systems and manufacturers:

This list is not exhaustive, and the specific terminology and implementation can vary between manufacturers. However, it highlights the growing prevalence of these sophisticated handling systems.

5. Active Cornering Enhancement System Problems

While active cornering enhancement systems offer significant benefits, they can also experience problems that require expert diagnosis and repair. Common issues include:

• Sensor Malfunctions: Faulty wheel speed sensors, steering angle sensors, yaw rate sensors, or other sensors can provide incorrect data to the ECU, leading to system malfunctions or erratic behavior.
• Actuator Failures: Active anti-roll bar motors, adaptive dampers, torque vectoring differential components, or active rear steering actuators can fail due to wear and tear, electrical issues, or hydraulic leaks.
• ECU Problems: Although less common, the ECU itself can experience software glitches or hardware failures.
• Hydraulic System Issues (if applicable): Systems like Mercedes-Benz’s ABC rely on hydraulic pressure. Leaks, pump failures, or issues with the hydraulic fluid can cause system failure.
• Software and Calibration Issues: These complex systems often require precise software and calibration. Issues can arise after repairs or due to software bugs.

Diagnosing these problems often requires specialized diagnostic tools and a thorough understanding of the system’s operation.
