System Description

The steering operation condition by the driver and the information from multiple sensors are computed by the chassis control module, and a command is transmitted to the TCM.
Based on the command from the chassis control module, TCM shifts the gear ratio of the transaxle to the low side and applies the engine brake.
When the turn OFF the VDC function, active engine brake function is also turned OFF.
When the active engine brake (cornering control) function operates, operation display can be checked on the information display in the combination meter.
When the PERSONAL mode is selected, the active engine brake can be switched ON/OFF through the "Infiniti Drive Mode Selector" on the integral switch.
When a malfunction occurs in active engine brake control function, the master warning lamp illuminates and the information display in the combination meter informs the driver.

NOTE:

Active engine brake function may not be effective in all driving environments (traction conditions, etc.).
When active engine brake function operates, the needle of the tachometer will rise up, you may hear an engine noise and sense slight deceleration. These are not symptoms of malfunctions and indicate normal operating conditions.

CORNERING CONTROL

For the purpose of reducing the operation of switching to depress the brake pedal during cornering, the operation information of the driver is computed by the chassis control module and a command is transmitted to TCM.
Based on the command from the chassis control module, TCM shifts the gear ratio of the transaxle to the low side and applies the engine brake.

BRAKING CONTROL

For the purpose of improving the feeling of effectiveness of the brake when decelerating, the brake operation amount of the driver is computed by the chassis control module and a command is transmitted to TCM.
Based on the command from the chassis control module, TCM shifts the gear ratio of the transaxle to the low side and applies the engine brake.
