摘要： An electric energy dissipating system (10b) for a vehicle. The system (10b) comprises an electric power system (12) configured to be electrically connected to an electric traction motor (80,82) of the vehicle and configured to receive and store electric power generated by the electric traction motor (80,82) during braking, a fluid conduit (14), an air flow producing unit (16) configured to provide a pressurized air flow through the fluid conduit (14), an electric machine (18), and a transmission arrangement (20). The electric machine (18) is configured to be powered by the electric power system (12) so as to drive the air flow producing unit (16) via the transmission arrangement (20) in order to dissipate energy from the electric machine (18). The transmission arrangement (20) comprises a first shaft (22) and a second shaft (24). The first shaft (22) is driven by the electric machine (18) and the second shaft (24) drives the air flow producing unit (16). The second shaft (24) rotates at higher speed than the first shaft (22).

摘要： A vehicle braking energy recovering method and apparatus is disclosed. The method includes: obtaining current location information of a vehicle; determining a current road scenario based on the current location information of the vehicle; determining the current road scenario based on a mapping relationship between a road scenario and a weight; determining a safe distance and a safe speed of the vehicle based on the weight; determining a target torque based on the safe distance and the safe speed of the vehicle; and controlling, based on the target torque, a motor of the vehicle to recover braking energy. The vehicle braking energy recovering method and apparatus can improve a braking energy recovery rate.

摘要： A working vehicle 10 is provided comprising: an electric storage device 50; a traction motor 52 configured to propel the working vehicle 10 and to generate electrical energy when braking; a hydraulic system 100 comprising a hydraulic pump 110 driven by a load motor 112, a hydraulic actuator 24, 34, 36 and a control valve 118; and a control system 200. The control system 200 is configured to: determine a state of charge of the electric storage device 50; induce additional load on the hydraulic system by directing the load motor 52 to drive the hydraulic pump 110 and actuating the control valve 118 to direct flow of hydraulic fluid to the hydraulic actuator 24, 34, 36 when the state of charge is at or above a predetermined threshold.

摘要： The disclosure relates to a method for operating an electric vehicle. The method comprises receiving an information about an upcoming speed reduction (S1) and determining a release position or a release time at which a drive pedal of the electric vehicle is to be released, such that at a position corresponding to the speed reduction the electric vehicle travels at a speed corresponding to the speed reduction (S2). Moreover, a first notification position is determined for providing a first notification signal concerning the release of the drive pedal (S3). Alternatively or additionally a first notification time is determined for providing a first notification signal concerning the release of the drive pedal (S3). Furthermore, a data processing system is presented. The data processing system comprises data processing means for carrying out the above method. Additionally, an electric vehicle comprising such a data processing system is explained. Also, a corresponding computer program product and a corresponding computer-readable medium are shown.

摘要： The present invention relates to a driveline (12) for a vehicle (10). The driveline (12) comprises a set of electric machines (22, 24, 26) with variable regeneration efficiency level. The set of electric machines (22, 24, 26) with variable regeneration efficiency level comprises at least one electric machine (22, 24, 26) with variable regeneration efficiency level. An electric machine (22, 24, 26) with variable regeneration efficiency level is such that the relation between electric energy and thermal energy produced the electric machine (22, 24, 26) during regeneration can be varied.
The driveline (12) further comprises a cooling system (36) connected to each electric machine (22, 24, 26) in the set of electric machines (22, 24, 26) such that the cooling system (36) can remove heat generated by each electric machine (22, 24, 26) in the set of electric machines (22, 24, 26). The driveline (12) further comprises a control system (44) adapted to receive status information indicative of a current status of the driveline (12) and for at least one, preferably each one, of the electric machine in the set of electric machines (22, 24, 26) with variable regeneration efficiency level:
- receive braking torque information indicative of a requested braking torque to be produced by the electric machine (22, 24, 26);
- in response to the braking torque information and the status information, determine a target relation between the electric energy and the thermal energy produced by the electric machine (22, 24, 26);
- control the electric machine (22, 24, 26) such that the requested braking torque and the determined target relation between electric energy and thermal energy are obtained, and
- control the cooling system (36) in response to the determined target relation between electric energy and thermal energy for the electric machine (22, 24, 26).
