A method and system for enabling an autonomous vehicle detection process is provided. The method includes detecting a sensor reading, of a sensor integrated with an autonomous vehicle, exceeding a specified threshold value. Additional sensor reading from additional vehicles located within a specified distance of the autonomous vehicle are received and compared to the original sensor reading. In response, a fault condition associated with the sensor is determined and an associated notification is presented to an occupant of the autonomous vehicle.

A mobile work machine includes a frame; ground engaging elements movably supported by the frame and driven by a power source to drive movement of the machine; a moveable element movably supported by the frame to move relative to the frame; an actuator coupled to the moveable element to controllably drive movement of the moveable element; a control system that generates an actuator control signal, indicative of a commanded movement of the actuator, and provides the actuator control signal to the actuator to control the actuator to perform the commanded movement; a terrain identifier configured to identify a characteristic of terrain in a geographic area around the machine; and a stability system that determines whether the commanded movement will result in an unstable state of the machine based on the characteristic of the terrain and, if so, generates a restriction signal, restricting the commanded movement to avoid the unstable state.

An engine power delivery system provides bifurcated power-flow with transmission bypass. An engine power delivery system includes an engine that has an output element. A transmission has an input shaft coupled with the engine output element, wherein the engine is configured to generate more power than the transmission is capable of handling. A multi-speed gearing arrangement is included in the transmission and is coupled to the input shaft. An output shaft is coupled with the gearing arrangement and a vehicle axle is coupled with the output shaft to be driven thereby. A generator is configured to be intermittently driven by the engine. A motor is configured to receive electric power from the generator and to drive the vehicle axle without the transmission exceeding the maximum power rating.

A method for serial operation of a motor vehicle with a transmission having a first electric machine, which is operated as a motor for driving the motor vehicle, and a second electric machine, which is operated as a generator, includes, after a generation of a change-over signal, switching the first electric machine from the operation as a motor to the operation as a generator, and switching the second electric machine from the operation as a generator to the operation as a motor in order to drive the motor vehicle.

A method of providing a heating cycle for an after-treatment system is described. The method comprises initiating a pre-charge cycle of a DCDC converter and determining a temperature of the after-treatment system. In response to determining the temperature of the after-treatment system is below a threshold temperature and the pre-charge is complete, the method further comprises operating a solid-state switch to electrically connect a high voltage power source to a heating element to of the after-treatment system, and heating the after-treatment system with the heating element until the after-treatment system reaches the threshold temperature.

An eco-friendly vehicle and a transmission hydraulic pressure control method for the same are provided. The vehicle includes an oil pump that estimates an inner temperature without using a temperature sensor. The method includes determining a driver request output and determining a required hydraulic pressure corresponding to the request output. A temperature of an oil pump unit is estimated to operate an electric oil pump to supply a hydraulic pressure to a transmission, based on the required hydraulic pressure and driving status information. An output torque is then adjusted based on the estimated temperature.

A mobile work machine includes a frame, a set of ground engaging elements movably supported by the frame and driven to drive movement of the mobile work machine, a movable element movably supported by the frame to move relative to the frame, and an actuator coupled to the movable element to controllably drive movement of the movable element. The mobile work machine also includes a control system that generates an actuator control signal, indicative of a commanded movement of the actuator, and provides the actuator control signal to the actuator to control the actuator to perform the commanded movement. Further, the mobile work machine includes a stability system, coupled to the control system, that determines whether the commanded movement will result in an unstable state of the mobile work machine and, if so, generates a restriction signal, restricting the commanded movement to avoid the unstable state.

A method for controlling a hybrid vehicle having a motor and an engine includes: calculating a first startup reference value of the engine on the basis of requested power of the hybrid vehicle; measuring a current speed of the hybrid vehicle, and predicting a future speed of the hybrid vehicle; generating a compensation value needed to compensate for the first startup reference value of the engine on the basis of a difference between the current speed and the future speed of the hybrid vehicle; acquiring a second startup reference value of the engine by compensating for the first startup reference value on the basis of the compensation value; and controlling a startup operation of the engine according to the second startup reference value acquired through compensation.

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 vehicle control apparatus includes an engine, a refrigerant compressor, a lock up clutch, a throttle valve, and first, second, and third deceleration controllers. The second deceleration controller controls the lock up clutch to a slip state and controls the throttle valve openwise on the condition that the refrigerant compressor is in the stopped state on decelerated travel of a vehicle in a second speed region in which a vehicle speed is lower than a first vehicle speed and higher than a second vehicle speed lower than the first vehicle speed. The second deceleration controller controls the lock up clutch to a disengaged state and controls the throttle valve closewise on the condition that the refrigerant compressor is in the operative state on the decelerated travel of the vehicle in the second speed region.
