Publication number: 20220274618Abstract: A method manages a kilometer range of an electric-traction vehicle supplied with power by an electric battery including a usable capacity and a reserve.

Publication number: 20200346650Abstract: A method compensates for wheel torque interruption for a change in braking ratio in a vehicle with an electric traction unit linked to wheels by a gearbox that transmits, to the wheels, the braking torque of the electric traction unit in the deceleration phase over at least two transmission ratios, and a mechanical braking system acting on the wheels independently of the electric traction unit. The method includes defining a setpoint for mechanical braking torque at the wheels, depending on the control type of the electric traction unit, and the date of the downshift ratio change request to the gearbox. The mechanical braking torque setpoint is equal to the difference between an anticipated torque request to the electric traction unit and the estimation of the torque at the wheel, before the date of the end of the shift at the gearbox, if the electric traction unit is torque-controlled.Type: ApplicationFiled: September 21, 2017Publication date: November 5, 2020Applicant: RENAULT s.a.s.Inventors: Cedric CHANTREL, Marco MARSILIA
