  • Patent number: 10703201
    Abstract: A modular gearbox unit and drive system are provided. The modular gearbox unit and drive system may be part of a vehicle platform having multiple drivetrain mount areas including identical mount features disposed at each mount area. Each drivetrain mount area can receive a modular single-motor drive unit or a modular multiple-motor drive unit using the same mount or bolt pattern and features. These modular single-motor and multiple-motor drive units have a common bolt pattern and mating features that correspond to the mount features of the vehicle platform and/or vehicle frame. The modular gearbox unit and drive system allows a vehicle powertrain to be reconfigured, during or after assembly, quickly and easily using the same mount points.

  • Patent number: 10703192
    Abstract: A driveline for a vehicle includes a frame member, a knuckle, a control arm, a hub, an electric motor, and an axle member. The control arm couples the knuckle to the frame member. The hub is coupled to the knuckle and adapted to support a drive wheel for rotation about a wheel axis relative to the knuckle. The electric motor includes a rotor rotatable about a motor output axis. The motor is supported so that an orientation of the motor output axis relative to the knuckle and the frame member changes when an orientation of the control arm relative to the frame member changes. The axle member couples the rotor to the hub for torque transmission therebetween.

  • Patent number: 9841092
    Abstract: An electric drive module for transferring torque to wheels of a motor vehicle a planetary gearset having a first member driven by the rotor and a second member. A synchronizer restricts a third member of the planetary gearset from rotation when the electric drive module operates at a first drive ratio. The synchronizer transfers energy from the rotating rotor to the third member during a shift between the first drive ratio and a second drive ratio to match the rotational speeds of the rotor and the second member. A reduction unit includes an input member being driven by the second member and also includes an output member driven at a reduced speed relative to the input member. A differential assembly includes an input driven by the output member, a first differential output driving a first output shaft, and a second differential output driving a second output shaft.

  • Patent number: 9776621
    Abstract: During EV traveling in a CD mode, an electronic control unit determine that an engine is in a state where the engine is likely to be started when an electric power storage ratio SOC of a battery falls short of a threshold Sref, when a battery temperature Tb of the battery falls short of a threshold Tbref, when an output limit Wout of the battery falls short of a threshold Wref, when a temperature Tmg2 of a motor is higher than a threshold Tmg2ref, and when a torque limit Tm2lim of the motor falls short of a threshold Tm2limref. Then, the electronic control unit set a required torque Tr* by using a map for a CS mode in which the required torque Tr* is set to be lower than in a map for the CD mode.

  • Patent number: 9751401
    Abstract: A torque distribution control system comprises a torsion unit for detecting traction on wheels of a primary driving axle that is continuously engaged with a drive source or a source of torque power. The amount of traction detected is converted to a signal with variable signal strength, the signal strength correlating to the amount of traction detected by the torsion unit. The signal strength capable of being adjusted automatically based on select parameters and/or manually based on a driver's input. And, in response to the signal, actuators engage and control operations of the vehicle such as the drive source, a braking system, and/or an axle clutch, with the level of engagement dependent upon the signal strength.

  • Patent number: 9694663
    Abstract: A family of hybrid electric transmission arrangements share a common center housing, rear housing, two electric machines, power-split planetary gearset, and torque multiplication gearset. One arrangement additionally utilizes an overdrive gearset and an overdrive clutch. Another arrangement additionally utilizes two clutches and a brake to implement three operating modes. Since the components that differ between the two arrangements use the same general packaging space and all shift elements are hydraulically controlled via a front housing, the design of the front housing is also similar.

  • Patent number: 9676282
    Abstract: Nowadays people attempt to replace petrochemical engine vehicles by electric vehicles. However, up to now this attempt has not been successful yet for the insufficiency of safety, cruising range and convenience. When the electricity of battery is used up, the electric vehicle has to stop running and wait for charging and looking for charging stations, always make consumers give up the idea of buying electric vehicles. We have creatively design a range-extending, charging, and driving apparatus for an electric vehicle. It makes use of the clever configuration of wheel motor and planetary gear assembly, which can increase the cruising range, torque and speed of electric vehicle, and conduct charging while driving, and provides the auxiliary power fuel cell with the fuel of oxygen. Here electric vehicles cover all kinds of electric vehicles.
