TL;DR: In this paper, a hierarchical control strategy is brought forward for an electric vehicle with a two-speed automated mechanical transmission, and an off-line calculation and on-line look-up table method is adopted to obtain the optimal downshift point, and a series regenerative braking distribution strategy is designed.

TL;DR: In this article, a semi-brake-by-wire system, without the use of a pedal simulator and fail-safe device, is proposed to compensate for the hysteretic characteristics of the designed brake system while ensuring braking reliability and fuel economy when the anti-lock braking system (ABS) is triggered.

TL;DR: In this paper, a hybrid electric vehicle equipped with an automated manual transmission (AMT) was chosen as the study platform and the process and advantages of AMT downshifting were analyzed and the characteristics of regenerative braking were obtained with different gear positions and different, of which two kinds of downshifts strategy were proposed on basis.

TL;DR: In this paper, a model predictive control method with the correction of clutch wear based on the estimation of resistance torque is proposed for precise position control of the clutch, and the results both of simulations and bench experiments show that the proposed control scheme has a satisfying control performance.
