A 48V e-drive systems concept for mild HEVs will be revealed at the 9th International CTI Symposium, Novi, Michigan, 18th to 21st May, in a presentation by Drive System Design (DSD). In a second paper, the company will show how to take time and cost out of gearbox and differential casing development by using more accurate NVH simulation methods to optimise the design earlier in the engineering programme.
