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.

Method for operating a motor vehicle for improving working conditions of evaluation units in the motor vehicle, control system for performing a method of this kind, and motor vehicle having a control system of this kind

A method for operating a motor vehicle incorporates polling regarding the control of the motor vehicle, leading to an improvement in the working conditions of a plurality of evaluation units accessing sensor units of the motor vehicle. Control commands for controlling the motor vehicle are determined from this polling by a conflict checking unit. The conflict checking unit determines the feasibility of the control commands, taking into consideration predetermined verification criteria with regard to conflicts between the individual control commands and the practicability of the individual control commands. The conflict checking unit also determines a control specification for a vehicle control unit based on the feasibilities and certain decision criteria. Finally, the motor vehicle is controlled by use of the vehicle control unit in accordance with the control specification.

ADAPTIVE ACCELERATION CONTROL SYSTEMS AND METHODS
20220161796 · 2022-05-26 ·

Aspects of the subject technology relate to systems and methods for adaptively controlling acceleration of a vehicle employing one pedal driving functionality. A full release of an accelerator pedal of a vehicle is detected while the vehicle travels at a first non-zero speed according to a default accelerator pedal map. When the full release of the accelerator pedal is detected, the vehicle decelerates, and the first accelerator pedal map is switched to an adaptive accelerator pedal map. While the vehicle decelerates, the adaptive accelerator pedal map is adjusted according to reduction of a speed of the vehicle. When a depression of the accelerator pedal to reaccelerate the vehicle pedal is detected while the vehicle decelerates and before the speed of the vehicle reaches zero, the vehicle is controlled to reaccelerate the vehicle according to the adjusted adaptive accelerator pedal map without further decelerating the vehicle.
