Method for operating a vehicle having a driveline disconnect clutch
A method for operating a vehicle that includes a driveline disconnect clutch is described. In one example, the method adjusts torque of an electric machine in response to a estimated torque capacity of the driveline disconnect clutch. The estimated torque capacity of the driveline disconnect clutch is based on a combined inertia of a dual mass flywheel and the driveline disconnect clutch.
System and method to shift transmission in machines
A method for shifting a transmission in a machine. The method includes detecting a request for a directional shift of the transmission and determining a ground speed of the machine in response to the request. The method further includes overriding the request if the ground speed is above a ground speed threshold. Further, the method includes preparing the machine for the directional shift by limiting an output speed of a power source of the machine and by issuing a command to a brake unit of the machine to reduce the ground speed of the machine. Furthermore, the method includes validating and raising the request to the transmission to execute the directional shift if the ground speed is below the ground speed threshold.
Hybrid electric vehicle and method of controlling the same
Disclosed is a method of controlling a hybrid electric vehicle having a transmission, an engine, and first and second drive motors. The method includes: performing charging through the first drive motor using the power of the engine by engaging an engine clutch disposed between the engine and the first drive motor while a vehicle is stopped with the gear stage shifted to the parking (P) range; turning off the engine and controlling the clutch of the transmission to enter an open state when the gear stage is shifted to the driving (D) range; and commencing movement of the vehicle using the second drive motor alone or using at least one of the first drive motor or the engine together with the second drive motor based on at least one of requested torque, available torque of the second drive motor, or the speed of the first drive motor.

Method and device for controlling charging of vehicle battery
A method of controlling charging of a battery may include making, by a controller, the battery that supplies power to a drive motor start to be charged with a boosted voltage higher than a voltage of a fast charger by controlling a switch connecting the drive motor and the fast charger of a vehicle and a switch of an inverter driving the drive motor, for fast charging of the battery; determining, by the controller, whether a motor position sensor has failure according to an output signal of the motor position sensor which detects a position of the drive motor; engaging, by the controller, an engine clutch that is configured to connect or disconnect the engine of the vehicle and the drive motor, when the controller determines that the motor position sensor has the failure; and maintaining, by the controller, the fast charging for the battery when a rotation of the drive motor stops after the engine clutch is engaged.

Braking force controller
A braking force controller includes: a target jerk calculation unit; a first estimation unit configured to estimate an increment of braking force when a prescribed factor that increases braking force to be generated by the first actuator unit currently occurs; a second estimation unit configured to estimate the increment of the braking force when the prescribed factor occurs within a prescribed period; and a control unit configured to determine a negative jerk generated when the second actuator unit generates the braking force such that a sum of the negative jerk and the jerk generated by the first actuator unit without the prescribed factor becomes the target jerk. When the increment of the braking force due to the prescribed factor is larger than a prescribed value, the control unit corrects the determined negative jerk such that an absolute value of the negative jerk becomes smaller.
ELECTRIFIED MILITARY VEHICLE
An energy storage system for a military vehicle includes a lower support, a battery supported on the lower support, a bracket coupled to the battery, and an upper isolator mount coupled between the bracket and a wall. The upper isolator mount is configured to provide front-to-back vibration isolation of the battery relative to the wall.
