Watch out brief demonstration of Maruti Suzuki Celerio (Automatic Transmission) carried out at Unique Motors Pvt. Ltd. (Village Satroad, Jindal Marg, Hisar).
Maruti Suzuki is the first automaker to introduce AMT or as they call it – AGS, into the hatchback segment in India with the Celerio.
Auto Gear Shift is Suzuki’s newly developed automated manual transmission (AMT), equipped with the Intelligent Shift Control Actuator, an electric-hydraulic actuator that automatically performs clutch and shift operations. Auto Gear Shift combines the actuator and controller and directly mounts them in the transmission in order to unify the working components.
This permits synchronised control over the clutch, shifting, and engine for smoother gear changes. As well as bringing together the advantages of both manual and automatic transmissions, shifting time is shortened compared to conventional AMTs.
Knowing Auto Gear Shift
The gear box is neatly labelled where “N” stands for Neutral, “D” is for Drive, “R” denotes Reverse, “M” means Manual mode. In Manual mode, there are options of “+” to upshift gears and “-” which is used to downshift the gears.
Switching On
Ensure car is in neutral. Brake pedal is pressed. Crank on the engine (if the car is not in Neutral and brake pedal is not pressed, the car will not start. This is to ensure safety)
Drive Mode
The user presses the brake pedal and puts the gear lever in Drive ‘D’ position. The car sets in motion by virtue of Creep function with the release of brake.
The speed of car can be changed by pressing or releasing the accelerator pedal as per requirement.
In Drive “D” mode the most appropriate gear is automatically selected by the Auto Gear Shift system, based on the operation of the accelerator pedal and vehicle speed. With the increase in speed, the car moves up to a higher gear, highest being the 5th gear.
Optimum vehicle performance and fuel economy is obtained by smoothly/ lightly pressing and releasing the accelerator pedal. Aggressive pressing of the accelerator pedal will result in gear shifting at higher engine RPM which may adversely impact the fuel economy.
Manual Mode
To add to the flexibility, this Auto Gear Shift transmission also offers a Manual mode. For shifting to Manual mode, one has to simply shift the gear lever to “M” position.
Gear shifting is achieved by pushing the lever to the “+”and “-” for upshifting and downshifting respectively. Even while driving, the drive mode can be shuffled between “D” and “M” modes.
Stopping Car
Pressing the brake reduces the speed of the car. The gears shift down automatically. When the vehicle comes to a complete halt, press the brake pedal and shift the lever to “N”, Neutral.
It is crucial to check position of gear in the display on the instrument cluster to ensure it is in Neutral. Switch off engine and engage parking brake.
How AMT of Maruti Celerio Work
The brain of this actuator is the Transmission Control Unit (TCU) which is in addition to and pairs up with the electronic control unit (ECU). Information is fed to the TCU by an array of sensors including the throttle position sensor and the engine-rpm sensor, and the ECU. Based on the info, the TCU directs the hydraulic actuators to engage the clutch and shift up or down the gear range. Maruti engineers have given the Celerio an electric, drive-by-wire throttle to deliver driver inputs directly to the TCU.
Note :
1) In traffic, sometimes AMT system takes more time to engage the right gear; it could be that ECU taking more time to assert the right gear.
2) The AMT is only available in LXi and VXi while the ZXi version does get a music system. It means that music system is not available in any AMT version of celerio.
3) The AMT does not get any safety options, while the ZXi gets ABS. (optional)
4) The manual gear option will be helpful for those who would want more freedom to select gears while driving on highways.
Consideration
1) Water may damage the AMT unit during heavy rains and water logs. (1 in 100 cases may happen)
2) There can be wear and tear of clutch plate.
3) AMT auto can be troublesome on a quick overtake on highways.
4) The kind of engine vibration or shudder if on neutral with AC on, it could be due to small engine.
5) The auto shifter in the new Maruti Celerio is just the manual gearbox and a brainy appendage sitting on top of it.
