Methods and systems for an electric drive assembly are provided herein. In one example, a method for operation of an electric drive system is provided that includes coordinating operation of a first electric drive unit and a second electric drive unit based on a first power request.

A vehicle including an electric motor has improved operating performance of a brake lamp using regenerative braking. A method of controlling a brake lamp of the vehicle includes determining a tendency of a driver, calculating a corrected mass based on the determined tendency of the driver, and calculating corrected acceleration based on the corrected mass and regenerative braking torque of the electric motor. An on threshold is corrected based on a difference between a requested torque and the regenerative braking torque at a time at which an accelerator pedal is released, and the brake lamp is turned on based on the corrected on threshold and the corrected acceleration.

A vehicle control device includes a main control device, a sub-control device, and a temperature detection unit. The main control device includes a recognition unit that recognizes a peripheral situation of a vehicle, a driving control unit that controls steering and acceleration/deceleration of the vehicle independently from an operation of a driver, and a mode determination unit that determines a driving mode of the vehicle. The sub-control device is capable of controlling the vehicle in place of the main control device. The temperature detection unit detects a temperature of a second battery that is different from a first battery supplying power to the main control device and supplies power to the sub-control device. The mode determination unit changes the driving mode of the vehicle from the second driving mode to the first driving mode when a temperature of the second battery is lower than a predetermined temperature.

An apparatus for controlling operation of an electric vehicle of the present invention may comprise: an operation information collection unit that collects parameters for operation of an electric vehicle; a battery information collection unit that collects information on battery operation and condition; a manipulation information collection unit that collects manipulation information of a driver on the electric vehicle; a motor control means for driving a driving motor of the electric vehicle according to the collected manipulation information from the driver; and a derating adjustment unit that performs derating for reducing a ratio of an amount of power of the driving motor to a throttle angle, according to the collected information.

To provide a technique for reliably acquiring a required braking power during travel and for efficiently using a regenerative power generated during braking. A work vehicle calculates a regenerative power outputted from an electric motor and a target hydraulic driving power for driving a hydraulic pump, supplies the regenerative power to the generator motor operating as a motor and makes the generator motor consume the regenerative power in a case where the regenerative power is equal to or smaller than the target hydraulic driving power, and supplies the regenerative power to the generator motor operating as the motor and makes an exhaust brake consume a power equivalent to a difference between the regenerative power and the target hydraulic driving power in a case where the regenerative power is larger than the target hydraulic driving power.

An electrified vehicle, system, and method include an electric machine, a traction battery coupled to the electric machine, and a controller programmed to control wheel slip to provide high wheel slip to traverse deformable terrain, such as sand or loose soil, and lower wheel slip to avoid excessive soil removal beneath the wheels after detecting a vertical acceleration or heave event, such as after landing when driving over a jump or bump. When vehicle vertical acceleration exceeds a first threshold, and a ratio of a wheel angular acceleration to vehicle longitudinal acceleration exceeds a second threshold, the electric machine is controlled to limit wheel slip to a lower value that provides sufficient tractive force to maintain some forward motion. Otherwise, the electric machine is controlled to limit wheel slip to a higher value to accommodate higher vehicle speeds over the deformable terrain.

Demand associated with one or more vehicle systems can be predicted for a vehicle traversing a planned travel path. Based at least in part on the predicted demand, a control strategy can be determined for controlling operation of the one or more vehicle systems to optimize for efficiency, cabin temperature, component temperature, passenger comfort, etc. The one or more vehicle systems can be controlled, based at least in part on the control strategy, at least one of before the vehicle traverses the travel path, or as the vehicle traverses the travel path.

A method for controlling a rotating electrical machine of a motor vehicle is disclosed. The motor vehicle includes a thermal drive chain including a heat engine connected to a gearbox by means of a clutch. The electrical machine is integrated in the thermal drive chain or in a drive chain independent of the heat engine. When the clutch is open and the rotating electrical machine operates in motor mode in order to ensure the electrical operation of the motor vehicle, the method includes: generating a setpoint torque corresponding to a desire of the driver to accelerate; determining a pulsed compensation torque for torque oscillations generated by the drive chain; combining the setpoint torque and the previously determined pulsed compensation torque in order to obtain a resulting modified setpoint torque; and applying the resulting modified setpoint torque to the rotating electrical machine.
