Techniques control a utility vehicle. Such techniques involve storing electric power in a lithium battery of the utility vehicle. Such techniques further involve operating a motor controller of the utility vehicle in a normal mode in which the motor controller provides electric power from a lithium battery of the utility vehicle to an electric motor of the utility vehicle to turn one or more ground engaging members of the utility vehicle. Such techniques further involve, after operating the motor controller in the normal operating mode, operating the motor controller in a walkaway mode in which the motor controller configures the electric motor to provide braking torque.

A computing device implemented method includes receiving one or more signals that represent an angular speed of a permanent magnet electric motor of a hybrid electric vehicle, the one or more signals being provided by an angular sensor connected to the electric motor, receiving a signal representing a voltage from the electric motor, the voltage being a direct axis voltage component of a three-phase motor model, determining if the angular speed is within a predetermined threshold, calculating an error angle representing a correction factor for an alignment of the electric motor based on a ratio of the voltage and the angular speed, storing the correction factor, and determining a binary indication of a status of error angle, and repeating the steps until the binary indication is positive.

Vehicles may be composed of a relatively few number of “modules” that are assembled together during a final assembly process. An example vehicle may include a body module, a first drive module coupled to a first end of the body module, and a second drive module coupled to a second end of the body module. One or both of the drive modules may include a pair of wheels, a battery, an electric drive motor, and/or a heating ventilation and air conditioning (HVAC) system. One or both of the drive modules may also include a crash structure to absorb impacts. If a component of a drive module fails or is damaged, the drive module can be quickly and easily replaced with a new drive module, minimizing vehicle down time.

A motor vehicle includes first and second drive axles coupled to respective sets of road wheels, torque actuators inclusive of rotary electric machines configured to transmit respective output torques to the drive axles, and a main controller in communication with the torque actuators. The controller receives vehicle inputs indicative of a total longitudinal and lateral motion request. In response, the controller calculates a total longitudinal torque request and/or a total longitudinal speed request, a yaw rate request, and a lateral velocity request, then determines, using a cost optimization function, a torque vector for allocating the total longitudinal torque request and/or speed request, the yaw rate request, and the lateral velocity request to the drive axles within predetermined constraints. The controller also transmits a closed-loop control signal to each torque actuator or local controllers thereof to apply the torque vector via the drive axles.

A processing device of a server provides a predetermined price, based on battery information received by a communication device, to a user of a vehicle that transmits the battery information. The processing device provides a user of a vehicle transmitting second information as the battery information with a price higher than that provided to a user of a vehicle transmitting first information as the information, it being determined that there is a larger need for collecting the second information than the first information.

The apparatus and system for integrating an electric motor into a vehicle may convert a vehicle from an internal combustion vehicle to a hybrid-electric vehicle. One or more electric motors may be integrated into a powertrain between an internal combustion engine and a transmission. A supervisory controller may monitor and control operation of the internal combustion engine, clutching assembly, transmission, one or more electric motors, or any combination thereof to add mechanical power to the powertrain, remove mechanical power from the powertrain, or neutrally balance the transfer of mechanical power between the powertrain and the one or more electric motors. This conversion may be operable to produce torque from both internal combustion and electrical sources and may be operable to recover energy via regenerative braking. The conversion may be performed with little downtime and with the basic fundamental knowledge of a savvy car enthusiast.

There is provided with a driving machine capable of easily performing switching from a power saving mode to an engine drivable mode. A driving machine comprises an engine; a battery; an operation unit including an emergency stop switch that stops the engine; and a control unit having operation modes, the operation modes including a normal mode in which the engine is drivable and a power saving mode in which the engine is not drivable and a power consumption amount of the battery is suppressed to be smaller than a power consumption amount of the battery in the normal mode, wherein the control unit switches from the power saving mode to the normal mode based on an input of the emergency stop switch when the operation mode is the power saving mode.

An engine unit controller (EUC) in connection with a hybrid opposed piston engine can receive real-time movement data of a crankshaft via a crank position sensor. It can simultaneously receive current data of an electric motor that partially controls the crankshaft. With the known engine constants, the EUC can determine instantaneous combustion pressure data based on the movement data and the current data. Such combustion pressure data can be used to optimize the engine's performance in real-time.
