4. Self-adaptive driving habits
TCU (Transmission Control Unit) will
automatically adjust gear shift points
according to personal driving habits.
If a driver controls a car by slightly
enabling accelerator for long, TCU
should
identify the driver's
preference of low gear and low fuel
consumption and the system will
lower the gear-up point. However, if
No Failure Solution
1
Not normal
transmission oil
Shift gear to N, 1, 2, 3 and R and limit the car
speed at 40km/h
2 Not normal water level
Shift gear to N, 1, 2, 3 and R and limit the car
speed at 40km/h
3 ABS failure
Shift gear to N, 1, 2, 3 and R and limit the car
speed at 40km/h
4
Failure of input shaft
rotating speed sensor
Shift gear to N, 1, 2, 3 and R and limit the car
speed at 40km/h
5
Failure of car speed
sensor
Shift gear to N, 1, 2, 3 and R and limit the car
speed at 40km/h
6
Failure of gear position
sensor
Shift gear to N, 1, 2 and R and limit the car
speed at 40km/h
3. Limp Home
Upon
a serious unrecoverable
failure, the system will enable the
function of "Limp Home" to ensure a
car reaches a maintenance point
most possibly for a repair. After the
function is enabled, engine output
torque,
gear shift and other
functions are limited. Solutions to
failure are specified below.
the driver prefers to drive the car by heavily using accelerator, TCU will also
identify the preference for larger power. Thus, the system will increase critical
speed of shifting gear to acquire higher acceleration performance.
