VEHICLE POWERTRAIN SYSTEM USING PERCEPTION SENSING
A powertrain system may determine a power distribution for one or more power sources of a vehicle. The powertrain system may be coupled to a perception system that may provide perception data indicating a scenario, situation, or environment that has been encountered by the vehicle. The powertrain system may include a rule based system and/or a machine learning model that may generate the power distribution based on one or more of the perception data and a power request.
Hybrid Electric Vehicle and Method of Controlling Driving Thereof
A method of controlling driving of a hybrid electric vehicle having an engine connected to main drive wheels via a transmission and a motor connected to auxiliary drive wheels includes setting a drive mode, controlling an input torque of the transmission in response to an extent of depression of an accelerator pedal (APS) according to the drive mode, performing distribution of drive power to the main drive wheels and the auxiliary drive wheels and variable shift-pattern control based on a result of a comparison between an amount of slip of the main drive wheels and the amount of slip of the auxiliary drive wheels, and determining whether to perform variable shift-time control in consideration of a type of the variable shift-pattern control or a number of revolutions per minute (RPM) of the engine at beginning of a shift.
Systems and Methods for Providing a Vehicle with a Torque Vectored K-Turn Mode
Systems and methods are provided herein for operating a vehicle in a K-turn mode. The K-turn mode is engaged in response to determining that an amount that at least one of the front wheels of the vehicle is turned exceeds a turn threshold. While operating in the K-turn mode, forward torque is provided to the front wheels of the vehicle. Further, backward torque is provided to the rear wheels of the vehicle. Yet further, the rear wheels of the vehicle remain substantially in static contact with a ground while the front wheels slip in relation to the ground.
METHOD FOR GENERATING A SETPOINT FOR THE COMBINED CONTROL OF A WHEEL-STEERING SYSTEM AND OF A DIFFERENTIAL BRAKING SYSTEM OF A MOTOR VEHICLE
A method generates a setpoint for controlling a steering system and a differential braking system of a motor vehicle. The method includes: acquiring a value relating to a total yawing moment to be applied to the motor vehicle such that it follows a required path, and the speed of the motor vehicle, calculating, as a function of the speed, at least one threshold relating to the maximum proportion of the total yawing moment that the steering system or that the differential braking system can provide, determining, as a function of the threshold, a distribution rate relating to the proportion of the total yawing moment that the steering system or that the differential braking system must provide, and generating a setpoint for controlling the steering system and the differential braking system as a function of the distribution rate and of the value relating to the total yawing moment.
Method for Controlling ESA System of a Vehicle and ESA System
Provided are methods for controlling ESA system of a vehicle and an ESA system. The method includes: generating a trajectory to avoid an obstacle in front of the vehicle; obtaining a target yaw rate and yaw moment according to the trajectory; allocating the target yaw moment to one or more chassis actuators; controlling the one or more chassis actuators according to allocated yaw moments. The cooperation of actuators is implemented for more safe evasion.
Systems and methods for providing towing acceleration assistance during in-flight charging of electrified vehicles
Systems and methods for coordinating and providing towing acceleration assistance between towing vehicles and towed vehicles during vehicle towing events are disclosed. The towing acceleration assistance may be provided by the towed vehicle in the form of an assistive propulsive torque to assist the towing vehicle with acceleration during the towing event when one or more vehicle conditions indicate a need for the towing acceleration assistance. The towing acceleration assistance may end when the one or more vehicle conditions no longer indicate the need for the towing acceleration assistance.
Systems and methods for road disturbance detection and torque vectoring control
Systems and methods for road disturbance detection and torque vectoring control. A vehicle may comprise: a torque vectoring system for independently varying torque to a plurality of wheels, an external sensor suite, and an electronic control unit. The control unit may comprise one or more processors and memory storing executable instructions that, as a result of execution by the one or more processors, cause the one or more processors to implement an appropriate torque vectoring strategy. The torque vectoring strategy may comprise biasing torque towards or away from a wheel/motor/axle.
ECMS-based PHEV four-drive torque distribution method
An ECMS-based PHEV four-drive torque distribution method is disclosed. The method comprises: step 1, calculating an equivalent fuel consumption factor; step 2, calculating instantaneous total equivalent fuel consumption rate; step 3, converting all operating torque combinations of an engine, a BSG motor and a rear axle motor into the operating torque of a driving wheel, and determining the operating torque range of each power source; step 4, solving the minimum value of the instantaneous total equivalent fuel consumption rate within the actual operating torque range of each power source; and step 5, taking the operating torque of each power source corresponding to the minimum instantaneous total equivalent fuel consumption rate as the PHEV optimal operating torque for distribution.
Control apparatus for electric vehicle, control system for electric vehicle, and control method for electric vehicle
Provided is control apparatus for an electric vehicle, which is capable of suppressing simultaneous slip of front and rear wheels. The control apparatus for an electric vehicle controls a front electric motor and a rear electric motor so that a difference between a torque command value of the front electric motor and a torque command value of the rear electric motor is larger than a predetermined value.
DRIVETRAIN OVERLOAD PROTECTION FOR WORK VEHICLES USING POWER BOOST
Overload protection systems and methods are provided for controlling the amount of energy delivered to the drivetrain of work vehicles including axles, transmission, and other components thereof including for vehicles using power boost. A sensor in operative communication with a primary power equipment unit driving a transmission of a work vehicle generates a torque signal representative of torque delivered to the transmission by the primary power equipment unit. The overload protection method and system uses the torque signal to control the torque delivered to the transmission of a work vehicle by the primary power equipment unit.
