ACTIVE STABILITY ASSIST : System Description

- Combination of Active trace control function and Brake force distribution function is named to as Active stability assist. Active trace control function is available for models with ICC system.
- Active stability assist system is aimed to smooth the vehicle movement utilizing VDC function for enjoyable driving with reliable feeling of the driver.
- Active trace control function
- Active Trace Control helps enhance the transition from braking into and then accelerating out of corners.
Active Trace Control utilizes the vehicle's VDC system to help improve cornering feel by automatically applying brakes, or smoothing engine torque characteristics while accelerating. Furthermore, Active Trace Control will apply selective braking to help create increased steering response in S-turns. For example, if driving through an S-turn that starts with steering to the right, the right-side brakes are engaged to create a yaw moment and help turn the vehicle. When steering back to the left, left-side brakes are engaged. Refer to
"ACTIVE STABILITY ASSIST : Active Trace Control Function" Active Trace Control Function.
- Brake Force Distribution function
Revision: March 20122013 Infiniti JX
- During braking, Brake force Distribution optimizes the distribution of brake force to each of the four wheels depending on the state of the turn detected by driver's steering and some sensors. Brake force Distribution helps provide a more stable and secure feeling. Refer to "System Diagram" System Diagram.
- Active trace control can be switched to operational status or non-operational status by operating VDC OFF
switch to ON/OFF.
