Operation Characteristics

WARNING: This page is about a different car, the 2012 Infiniti M35h. However, it is still accessible from the selected car via links, so may be relevant.

Active Trace Control helps enhance the transition from braking into and then accelerating out of corners. Active Trace Control utilizes the vehicle's electrically-driven intelligent brake system to help improve cornering feel by automatically applying brakes, or smoothening engine/traction motor 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.

Brake control amount and engine/traction motor output are controlled according to steering operation status by the driver and vehicle cornering status.

By preventing a sudden torque change, vehicle behavior moderates. As a result, accelerator pedal operation by the driver is improved.
