Hino Profia Hy­brid for 2019

Owner Driver - - Tech Briefs - – Rob McKay

FOUR YEARS af­ter flag­ging a hy­brid driv­e­train for its Profia heavy-duty truck, Hino has an­nounced plans to launch the low-emis­sions ver­sion of the ve­hi­cle in Ja­pan next sum­mer.

The move is linked to the man­u­fac­turer’s ‘En­vi­ron­men­tal Chal­lenge 2050’ un­veiled last Oc­to­ber with the aim of re­duc­ing car­bon diox­ide emis­sions from its ve­hi­cles by 90 per cent to zero from man­u­fac­tur­ing to dis­posal and from within its fac­to­ries by that date.

“In or­der to achieve this, we be­lieve that it is es­sen­tial to im­prove the fuel con­sump­tion per­for­mance of heavy-duty trucks, which ac­counts for ap­prox­i­mately 70 per cent of the Hino ve­hi­cles’ to­tal CO2 emis­sions, and we have ad­vanced tech­nol­ogy devel­op­ment,” Hino says.

Aus­tralia is plan­ning for what equates to a hy­brid ver­sion of the Hino 700, ac­cord­ing to Hino Mo­tor Sales Aus­tralia gen­eral man­ager – brand and fran­chise devel­op­ment Bill Gille­spie.

Hino is promis­ing an “in­no­va­tive large truck that com­bines en­vi­ron­men­tal per­for­mance and safety per­for­mance at a high level” in the Profia Hy­brid. And, in what it de­scribes as a “world first”, the ve­hi­cle will use ar­ti­fi­cial in­tel­li­gence (AI) to fo­cus on road and route con­di­tions.

“Large-sized trucks have been re­garded as un­suit­able for hy­brids be­cause of the low fre­quency of start­ing and stop­ping mainly by con­stant-speed driv­ing on ex­press­ways,” the group says. “Hino fo­cused on the fact that its de­cel­er­a­tion en­ergy on the de­scend­ing slope is very large be­cause of its mass.

“We have de­vel­oped a new hy­brid sys­tem adopt­ing the world’s first tech­nol­ogy that pre-reads the gra­di­ent on the route based on 3D map in­for­ma­tion etc., pre­dicts the travel load by AI, and per­forms op­ti­mal hy­brid con­trol.

“As a re­sult, by ef­fi­ciently re­gen­er­at­ing and util­is­ing the de­cel­er­a­tion en­ergy, we re­alised the fuel econ­omy ef­fect un­der the driv­ing con­di­tions spe­cific to heavy-duty trucks. About 15 per cent re­duc­tion in CO2 emis­sions is ob­tained for diesel ve­hi­cles in in-house test­ing.

“For our cus­tomers, we can ex­pect to save op­er­at­ing ex­penses by re­duc­ing fuel con­sump­tion while main­tain­ing ba­sic per­for­mance and us­abil­ity as trucks of load­ing ca­pac­ity and cruis­ing dis­tance equiv­a­lent to diesel cars.

“In ad­di­tion, it re­duces noise and vi­bra­tion dur­ing run­ning due to mo­tor run­ning, and con­trib­utes to re­duc­ing driver’s fa­tigue. It also has an ex­ter­nal power sup­ply func­tion and can be used as an emer­gency power sup­ply de­vice in the event of a dis­as­ter.”
