Hybrid vehicle and driving control method therefor
A hybrid vehicle and a control method are provided. The method of controlling a hybrid vehicle including a motor, an engine, and an engine clutch disposed between the motor and the engine includes determining whether to enter a first mode in which both the engine and the motor operate without engagement of the engine clutch, based on at least a first condition related to an accelerator pedal and a second condition related to a required torque condition, determining torque of the motor in consideration of at least required torque upon determining entry into the first mode, and determining an operating point of the engine based on engine generation power to be supplied to the motor with power of the engine.
CONTROL DEVICE OF VEHICLE
In a case where a predetermined switching operation to a state in which a traveling position is selected from a state in which another shift position of a mechanical transmission device is selected is performed by a driver, a quick engagement command to quickly engage a predetermined engagement device is performed in a state in which output of a predetermined torque is stopped, and then a rapid garage control of increasing a rotation speed of an electric motor at a rotation speed equal to or higher than a predetermined rotation speed is executed. The rapid garage control is executed in a case where a predetermined start condition is established.
Vehicle control method and vehicle control system
Provided is a vehicle control method that performs basic self-driving control configured to automatically control the travel of a host vehicle based on an intervehicle distance between the host vehicle and a preceding vehicle. When a traffic jam on a travel lane of the host vehicle is detected, low torque travel control configured to cause the host vehicle to travel by a drive torque lower than a drive torque determined based on the basic self-driving control is performed, and when the intervehicle distance exceeds, in the low torque travel control, a predetermined upper limit distance larger than a set during-vehicle-stop intervehicle distance serving as a reference for the start or the stop of the host vehicle in the basic self-driving control, the low torque travel control is switched to the basic self-driving control.
Movement distance calculation device
A movement distance calculation device includes: a first movement distance calculation unit which calculates a first movement distance of a movable body based on plural rotation speeds of plural wheels of the movable body and a steering angle of the movable body; a vector detection unit which detects a movement vector of an object included in the acquired images as defined herein; a second movement distance calculation unit which calculates a second movement distance of the movable body based on the movement vector; a first reliability determining unit which determines reliability of the calculated first movement distance as defined herein; a second reliability determining unit which determines reliability of the calculated second movement distance as defined herein; and a movement distance determining unit which determines a movement distance using at least one of the calculated first movement distance and the calculated second movement distance as defined herein.
SYSTEM AND METHOD FOR SELECTIVE DERATING OF SELF-PROPELLED WORK VEHICLE PARAMETERS BASED ON OPERATING MODES
A method is provided for controlling a self-propelled work vehicle comprising a work attachment and at least left and right ground engaging units driven by respective first and second drivetrains. Upon determining transition from a first operating mode to a second operating mode (e.g., creep mode), the method includes selectively derating at least a portion of the drivetrain speed commands corresponding to propulsion of the work vehicle (e.g., the average of left and right track speeds), independent of a portion of the drivetrain speed commands corresponding to steering (e.g., the difference between the track speeds). The derate value may optionally be applied only to propulsion commands that produce forward motion, and not for reverse motion. Separate (non-zero) derate settings may optionally be provided for reverse and/or steering functions. Derate functionality may optionally be implemented upon detecting particular types (e.g. dozer) of attachments, or an associated work state.
METHODS AND SYSTEMS FOR START/STOP
Methods and systems are provided for a start/stop feature. In one example, a method includes adjusting start/stop conditions in response to a vehicle operator customizing start/stop conditions. The vehicle operator customizes start/stop conditions for a plurality of different driving conditions.
Electric drive vehicle with low speed creep
Systems and methods to control the vehicle speed of a vehicle includes a controller communicatively coupled to a motor and a brake mechanism. The controller is structured to receive an indication of a desired change in the vehicle speed, activate a motor speed governor responsive to the brake mechanism being in a released state, adjust an output torque responsive to the vehicle speed, wherein as a load corresponding to the motor increases the vehicle speed decreases.
Control Unit for Providing a One-Pedal Feel and/or a Creep Function
A control unit for a motor vehicle which includes at least one electric machine for driving one or more wheels of the vehicle and at least one friction brake is provided. The control unit is configured to determine that a one-pedal feel function is to be provided via an acceleration pedal of the vehicle and/or a creep function is to be provided via a brake pedal of the vehicle. Additionally, the control unit is configured to operate the electric machine at least temporarily in combination with the friction brake in order to provide the one-pedal feel function and/or the creep function.
Vehicle traveling control apparatus
A vehicle traveling control apparatus comprises a driving support ECU. The driving support ECU determines whether or not a driver of a vehicle is under an abnormal state where the driver losses an ability to drive the vehicle. The driving support ECU executes a deceleration control to decelerate the vehicle after an abnormal determination time point at which it is determined that the driver is under the abnormal state. The driving support ECU decelerates a vehicle speed of the vehicle to within a predetermined low vehicle speed range and thereafter, causes the vehicle to travel at a speed within the low vehicle speed range.
System and method to control the velocity of a vehicle
A system and method for controlling the velocity of a vehicle includes a processor, a velocity sensor in communication with the processor, a throttle actuator in communication with the processor, and a brake actuator in communication with the processor. The processor is set either the throttle position of the vehicle via the throttle actuator or the brake pedal position of the vehicle via the brake actuator based whether the augmented acceleration is greater than or equal to a gear acceleration, whether the actual velocity is above a crawl speed, and a lookup table.
