Method, computer-readable medium, system, and vehicle comprising said system for supporting energy-efficient deceleration of the vehicle
A method for supporting energy-efficient deceleration of a vehicle includes determining a reference deceleration depending on a current speed or a speed profile of the vehicle, determining a starting time point and a starting speed of a deceleration of the vehicle, and determining a real energy consumption and a real distance between the starting time point and a current time point and/or ending time point of the deceleration. The method also includes calculating a reference time and a reference distance for a deceleration with the determined reference deceleration between the determined starting speed and the current speed and/or the speed at the ending time point of the vehicle, calculating an energy consumption for a differential distance from the determined real distance and the calculated reference distance, and calculating a real total energy consumption as the sum of the determined real energy consumption of the deceleration and the calculated energy consumption for the differential distance. Further, the method includes calculating a reference energy consumption for the reference deceleration from the starting speed to the current and/or ending speed depending on a predefined deceleration type of the reference deceleration and/or depending on the determined real energy consumption of the deceleration, and then providing an energy-saving potential on the basis of a difference between the real total energy consumption and the calculated reference energy consumption.
Vehicle control method and control device
A vehicle control method for executing a sailing stop control when a drive source stop condition is established while a vehicle is traveling. The sailing stop control stops a drive source of the vehicle and releases an engaging element provided between the drive source and a drive wheel such that the vehicle travels under inertia. The vehicle control method acquires information on a road on which the vehicle will travel, and then determines whether there is a section on a route where the sailing stop control can be executed based on the information. Upon determining a section exist capable of the sailing stop control, the vehicle control method estimates a power shortage amount, which is a shortage amount of power during sailing stop control, based on the information, and charges a battery with power required to cover the power shortage amount prior to starting the sailing stop control.
Vehicle control device
A vehicle control device applicable to a vehicle including an engine includes an electric motor coupled to the engine, a hydraulic clutch, a solenoid control valve, a first travel control unit, a second travel control unit, and a fail-safe control unit. The hydraulic clutch is engaged when hydraulic oil is supplied and disengaged when the hydraulic oil is discharged. The solenoid control valve includes a solenoid. The solenoid control valve supplies the hydraulic oil to the hydraulic clutch when the solenoid is in a non-energized state, and discharges the hydraulic oil when the solenoid is in the energized state. The first travel control unit executes an engine traveling mode, and the second travel control unit executes an inertial traveling mode. The fail-safe control unit drives the electric motor when the solenoid is switched from the energized state to the non-energized state while the inertial traveling mode is executed.
Driving assistance device, driving assistance method, and computer readable medium
A driving assistance device (10) is mounted in a mobile body (100). An abnormality detection unit (22) detects an abnormality in a sensor mounted in a peripheral body moving on a periphery of the mobile body (100). An assistance determination unit (23) reads a control pattern corresponding to a sensing area of a sensor whose abnormality has been detected by the abnormality detection unit (22), from a pattern storage unit (31). A path generation unit (24) generates path data indicating a moving path of the mobile body (100) to correspond to the control pattern.
ENERGY SAVING ACTIONS FOR AUTONOMOUS DRIVING SYSTEMS
A control command is provided to a vehicle control module that identifies one or more vehicle actions to be performed by the vehicle control module to control a position of an autonomous vehicle (AV) with respect to an external environment. Whether one or more conditions pertaining to the position of the AV with respect to the external environment are satisfied is determined. Responsive to determining that the one or more conditions pertaining to the position of the AV with respect to the external environment are satisfied, a first instruction is provide to the vehicle control module that permits the vehicle control module to deviate from the one or more vehicle actions identified in the control command and to perform an energy saving action with respect to the AV.
Systems and methods for idle coasting management
A system, method, and apparatus includes management of coasting during operation of a vehicle. Speed of a vehicle is monitored during a coasting event and is compared against a threshold to determine whether to remain coasting or re-engage an engine to a driveline. If instantaneous speed exceeds the threshold, predicted speed can be used to determine whether to permit short duration excursions, or to re-engage the engine to the driveline. These techniques can be used whether the vehicle is slowing down below a threshold or speeding up above a threshold.
