Auto components India - - COVER STORY - Text : Bhar­gav TS

The com­mer­cial ve­hi­cle man­u­fac­tur­ing com­pany, Ashok Ley­land (AL), has brought in more dig­i­tal fea­tures to its pow­er­train ap­pli­ca­tions to suit the In­dian road con­di­tions, cus­tomer ex­pec­ta­tions for bet­ter fuel ef­fi­ciency and to be ready for the strin­gent en­vi­ron­ment norms and BS VI emis­sion stan­dards. For these the com­pany has for­mu­lated new al­go­rithms for pow­er­train.

The en­gine con­trol unit or the pow­er­train con­trol unit de­ci­phers data from tyres, chas­sis through vi­bra­tions. Based on the data, the ac­tu­a­tors will be con­trolled for dif­fer­ent ter­rains. The con­trol unit mea­sures 15-20 pa­ram­e­ters based on which the pow­er­train oper­a­tions are op­ti­mised. The in­built al­go­rithms tunes the ac­tu­a­tors based on the logic de­rived from the data and de­liver the ut­most ef­fi­ciency ac­cord­ing to the road con­di­tions.

Brief­ing the pow­er­train’s fu­ture, Seshu Bha­ga­vathula, Chief Tech­nol­ogy Of­fi­cer of Ashok Ley­land, told Au­toCom­po­nents In­dia that, “The soft­ware in the fu­ture pow­er­train is ex­pected to mea­sure dif­fer­ent pa­ram­e­ters and by this way ef­fi­ciency is de­rived for dif­fer­ent road con­di­tions. By means of the data ob­tained by var­i­ous pa­ram­e­ters, we be­lieve 20% in­crease in ef­fi­ciency will be achieved. All this fea­tures could not be achieved with fully man­ual trans­mis­sion but only with au­to­mated man­ual trans­mis­sion (AMT) or fully au­to­matic trans­mis­sion.”
