Apparatuses, systems, and methods are provided for assisting a driver of a motor vehicle in driving on a predeter-mined racetrack. A sensor system is configured to detect a current position of the motor vehicle on the racetrack and an electronic control unit configured to control an actuator system of the motor vehicle. Predetermined brake point positions of the racetrack are stored in the electronic control unit. A current position of the motor vehicle on the racetrack is continuously detected. A relevant remaining driving time from the current position to a relevant brake point position of the racetrack is determined using the electronic control unit. Corresponding limit values are stored in the electronic control unit for the relevant remaining driving time. When a corresponding limit value is not reached, the control device controls the actuator system of the motor such that the motor generates a signal to the driver.

A non-transitory storage medium for use in an information processing device in a vehicle control system. The storage medium stores: pieces of positional information; pieces of cumulative relative frequency distribution information associated with individual vehicle traveling directions, the pieces of cumulative relative frequency distribution information being related to data on traveling loads associated with the individual vehicle traveling directions on a plurality of vehicles having traveled through points indicated by the pieces of positional information, or data on traveling load amounts depending on a traveling time or a traveling distance from the points; and instructions that are executable by processors to perform functions comprising calculating a predicted value of the traveling load amount depending on the traveling time or the traveling distance from an arbitrary point based on the cumulative relative frequency distribution information associated with individual vehicle traveling directions at the arbitrary point.

Methods and systems are provided for a hybrid electric vehicle. In one example, a method may include delaying an electric-only operation of the hybrid vehicle in response to a powertrain temperature being less than a threshold powertrain temperature and an electric-only range being less than a distance between a current location and a recharging location. The electric-only operation may be initiated in response to one or more of the powertrain temperature exceeding the threshold powertrain temperature and the electric-only range being equal to the distance.

The present disclosure provides a method for starting an unmanned vehicle. The method for starting the unmanned vehicle includes: in response to completion of a task of the unmanned vehicle at a current node, determining occupancy state information of a reference start position on a guide line, wherein the guide line is a preset driving route of the unmanned vehicle from the current node to a next node, the reference start position is a position on the guide line reached by the unmanned vehicle from a current position; in response to a determination that the occupancy state information is the occupancy state, projecting the current position of the unmanned vehicle to the guide line to determine an initial mileage value of the current position on the guide line; determining a reference start mileage value of the reference start position on the guide line; and generating a target start point sequence.

The Dynamic Vehicle Separation System (DVSS) according to the present application allows properly equipped vehicles in traffic to maintain safe and optimal separation distances (i.e., following distances), which are automatically and continually calculated based on numerous criteria. Vehicles are equipped with Dynamic Vehicle Separation Controllers (DVSCs) that communicate with each other to maintain proper separation distances among the vehicles.

An abnormality determination device is applied to a vehicle provided with a transmission configured to transmit power by rotation of a shaft. The abnormality determination device includes a processor and a memory. The memory configured to store mapping data that is data that defines mapping learned by machine learning. The processor is configured to execute an acquisition process and a determination process. The acquisition process is a process of acquiring a variable indicating a time-series data of a rotation speed of the shaft and using the variable as a value of an input variable of the mapping. The determination process is a process of determining whether an abnormality has occurred in the transmission based on a value of the output variable acquired using the value of the input variable and the mapping.

Disclosed is a method for optimizing the time gradient of the pressure increase in a fuel injection system of a hybrid motor vehicle. The method determines and uses the engine torque generated by the electric machine of the vehicle to reduce the engine torque generated by the internal combustion engine of the vehicle and allow the high-pressure pump of the internal combustion engine to generate, if applicable, a higher value of the time gradient of the pressure increase in the common supply chamber of its injection system.

The present disclosure relates to a method and a device for safety driving. The method includes: acquiring riding data of a current user of a self-balancing vehicle; comparing the acquired riding data with riding data corresponding to a plurality of preset user levels; and determining a user level of the current user of the self-balancing vehicle according to a result of the comparing. The riding data includes one or more of the following data: a riding time, a riding distance, a shaking frequency, a shaking arc magnitude, and a shaking time.

To achieve saving of fuel consumption and noise reduction by adopting a hybrid type and miniaturizing an engine and to ensure safe and reliable battery charging in a case in which a charge amount of a battery is quite insufficient, a hydraulic work machine includes: a gate lock sensor (28); a forced charging switch (41); a work machine monitor (43) that notifies an operator that a charging rate of a battery (33) falls to be lower than a critical charging rate; and a machine controller (46). The machine controller (46) actuates a generator motor (31) as a generator to forcedly charge the battery (33) when a gate lock lever (26) is operated to a lock position (D), an engine control dial (12) designates a low idle engine speed, and the forced charging switch (41) is operated.
