“…Since the multi-gear transmission and clutch can be canceled in the electric motorcycle owing to electric motor advantages, motorcycle launching and driving are only controlled by the throttle grip and braking is only controlled by the front brake lever and rear brake pedal. Electric motorcycle provides the option of using the motor for regenerative braking [6], [7] in addition to the front and rear mechanical brake actuators, which helps to recover the kinetic energy and reduce energy consumption. Regenerative braking also reduces the mechanical brake discs wear and heat degradation which bring maintenance requirements and safety problems in engine-driven motorcycles.…”

In this paper, the impact of riding posture and regenerative braking on electric motorcycle energy economy is described. The motorcycle longitudinal dynamic model is first built to describe the motorcycle acceleration, tyre load transfer and energy consumption. Through energy consumption analysis based on the world motorcycle test cycle-class 3-2 (WMTC 3-2), the low riding posture can save up to 22.65% of energy consumption than the high riding posture, and regenerative braking can help to save up to 7.65% of energy consumption, which demonstrates the benefit of riding posture control and regenerative braking on energy saving. It is also demonstrated that riding posture has an impact on the rear tyre load and the available rear tyre longitudinal force. At low tyre road friction conditions, higher riding posture can provide more rear tyre longitudinal force for accelerating and regenerative braking, which improves the motorcycle dynamic performance and energy economy.

Electric vehicle drivetrains are considered a way to reduce greenhouse gas emissions from road traffic. The use of electric drives in automotive vehicles offers advantages, such as the potential to recover energy during braking (regenerative braking). The limitation of the maximum air gap torque of the vehicle drive machine by several factors requires a temporary standalone or simultaneous use of the conventional vehicle wheel brake. In several studies, it is shown that during braking operations, the drive machine and the vehicle wheel brake can induce torsional oscillations in the drivetrain, which have a negative influence on the driving comfort and lead to a high mechanical load. To reduce these oscillations, the simultaneous use of an active anti-jerk control is necessary. Due to the problem of oscillation excitations caused by a brake intervention, the used drivability function (integrated prefilter, anti-jerk control) is investigated and optimized with regard to brake blending maneuvers and the effectiveness for damping torsional oscillations. Therefore, the dynamics of the drivetrain are adapted to the dynamics of the braking system using the prefilter, which leads to precise fulfilment of the driver’s braking desire, even during dynamic brake blending maneuvers. All investigations are carried out with a hardware-in-the-loop test bench to create reproducible results.
