Described herein are systems, methods, and non-transitory computer-readable media for implementing automated vehicle safety response measures to ensure continued safe automated vehicle operation for a limited period of time after a vehicle component or vehicle system that supports an automated vehicle driving function fails. When a critical vehicle component/system such as a vehicle computing platform fails, the vehicle is likely no longer capable of performing calculations required to safely operate and navigate the vehicle in an autonomous manner, or at a minimum, is no longer able to ensure the accuracy of such calculations. In such a scenario, the automated vehicle safety response measures disclosed herein can ensure—despite failure of the vehicle component/system—continued safe automated operation of the vehicle for a limited period of time in order to bring the vehicle to a safe stop.

An electricity generation system includes an internal combustion engine and at least one electricity generation motor that generates electricity upon an input shaft thereof being rotated by the internal combustion engine, wherein the internal combustion engine includes: a piston reciprocable in a cylinder; a valve actuating mechanism that actuates an intake valve and exhaust valve; a supercharger that compresses intake air to be delivered into the cylinder; and a fuel feeder, and wherein while the piston reciprocates once by starting from a top dead center and returning to the top dead center, the valve actuating mechanism actuates the intake and exhaust valves in such a manner as to provide a valve overlap period, the fuel feeder feeds fuel into the cylinder after closing of the exhaust valve, and an air-fuel mixture inside the cylinder is burned during a period in which both of the intake and exhaust valves are closed.

A vehicle communication system includes: a communication server and a vehicle control device. The vehicle control device includes at least one electronic control unit configured to: recognize a position of the host vehicle; acquire section information on the communication established section and the communication interrupted section; determine in which section, either the communication established section or the communication interrupted section, the host vehicle is traveling or is to travel; perform system driven control of the host vehicle based on the road condition information when the host vehicle travels in the communication established section; and perform driver driven control of the host vehicle when the host vehicle travels in the communication interrupted section.

A method for controlling an electric device including: a step of comparing the rotation speed of an internal combustion engine at the time when it has been determined that the internal combustion engine is to transition to a rotation stop state with a specified threshold; and a step of performing rotation-speed increasing control, in a case where the rotation speed of the internal combustion engine at the time of the determination is higher than the threshold, in which in a case where the rotation speed of the internal combustion engine at the time of the determination is not higher than the threshold, the rotation speed of the internal combustion engine is not made higher than the rotation speed at the time of the determination but is let to decrease to stop the internal combustion engine.

In one embodiment, a computer-implemented method for calibrating autonomous driving vehicles at a cloud-based server includes receiving, at the cloud-based server, one or more vehicle calibration requests from at least one user, each vehicle calibration request including calibration data for one or more vehicles and processing in parallel, by the cloud-based server, the one or more vehicle calibration requests for the at least one user to generate a calibration result for each vehicle. The method further includes sending, by the cloud-based server, the calibration result for each vehicle to the at least one user.

In a system having a hybrid powertrain having a piston internal combustion engine, and a motor/generator, and the motor generator being coupleable to a clutch and thereby to a gearbox, the engine further being equipped with a valvetrain control system operable to change the engine valve operation between a first mode in which the engine can operate in a conventional internal combustion mode and a second mode in which pumping losses are reduced when the engine is not operating in a conventional internal combustion mode. This allows it to be rotated without generating power, in a hybrid mode, with minimal losses.

A method of reducing cold start emissions in a series mode hybrid electric vehicle, including an internal combustion engine with an exhaust duct having a catalyst and a downstream oxygen sensor, an output of the combustion engine being connected to an electric generator with a power output of at least 10 kW that is connected to an electric motor which is coupled to a drive shaft of two or more wheels. The method includes detecting a cold start condition, injecting fuel into the engine such that combustion at a lambda value, λ, is achieved for which λ>1, running the engine at a speed of 1000 rpm or higher, determining if the efficiency of the catalyst reaches a first level, setting λ to about 1 after the predetermined efficiency level of the catalyst has been reached, and reducing the speed to working conditions when the catalyst efficiency reaches a second level.

A method of controlling an engine and a transmission of a vehicle includes: determining, by a controller, whether the engine is restarted after releasing the vehicle's SSC (Start & Stop coasting) or whether the vehicle is accelerating during NCC (Neutral Coasting control), determining an RPM and gear stage of the transmission if it is determined that the engine is restarted after releasing the vehicle's SSC or the vehicle is accelerating during NCC, determining a mild hybrid starter and generator (MHSG) target RPM and an MHSG target RPM gradient of the vehicle, performing, by the controller, MHSG RPM control of the vehicle to follow the MHSG target RPM and the MHSG target RPM gradient, determining whether the MHSG RPM slips compared to the MHSG target RPM, and performing proportional-integral-derivative (PID) control to follow the MHSG target RPM if the MHSG RPM slips compared to the MHSG target RPM.

A hybrid vehicle control method controls a hybrid vehicle. In this control method, a rotational speed command value for a power generation system is determined in accordance with a state of a drive system, a torque command value is determined for the power generation system such that the rotational speed of the power generation system reaches the rotational speed command value, a damping control is performed to suppress a characteristic vibration component generated in a connection between the engine and the power generator to calculate a final torque command value for the power generation system, and the torque command value is set as the final torque command value without performing the damping control upon determining a system resonance can occur that is caused by vibration of a component different from the characteristic vibration component.
