OPERATING POINT CONTROLLER
A system for controlling an operating point of a power source for a propulsive e-machine in a hybrid electric vehicle, including: a power train including a power source and at least one propulsive e-machine, wherein the power source includes an integrated starter generator and an internal combustion engine; at least one desired operating point for the power source including at least one characteristic parameter; an operating point component configured to query the at least one desired operating point and to selectively distribute the control of the at least one desired operating point to a control of the internal combustion engine or to a control of the integrated starter generator control.
CONTROL METHOD AND CONTROL SYSTEM OF HYBRID VEHICLE
A hybrid vehicle controlling method is provided. In response to an engine startup demand, when a vehicle target driving force is below a given value, an instruction hydraulic pressure for a hydraulic control circuit is set to a first pressure at which an increase rate in an engagement pressure at a start of engaging of a friction engagement element becomes below a given rate and maintained for a given time period, then set to a second pressure at which an engine-startup engagement pressure is applied to the friction engagement element and maintained until the engine startup is completed, and then set to a third pressure for setting the friction engagement element to an engaged state. When the target driving force is above the given value, the instruction hydraulic pressure is set to the second pressure and maintained until the engine startup is completed, and then set to the third pressure.
CONTROL METHOD AND CONTROL SYSTEM OF HYBRID VEHICLE
A method of controlling a hybrid vehicle is provided, which includes shifting a friction engagement element from a released state to a slipping or engaged state, and performing motor control where an engine is started using a motor in response to a startup demand of the stopped engine during vehicle traveling, applying as the motor control a first control in which a target speed to be set for the motor is instructed and feedback control of the motor is executed based on a speed detected by a motor speed sensor to be the target speed, determining whether a condition for switching the motor control from the first control to a second control in which a target torque to be outputted from the motor is instructed to cause the motor to output the target torque, is satisfied, and when determined to be satisfied, switching the motor control to the second control.
FAULT-TOLERANT TRACKING CONTROL METHOD FOR FOUR-WHEEL DISTRIBUTED ELECTRIC DRIVE AUTONOMOUS VEHICLE
The present disclosure provides a fault-tolerant tracking control method of a four-wheel distributed electric drive autonomous vehicle. The method depends on a typical four-wheel distributed electric drive vehicle structure, comprising: first, realizing real-time acquisition of an output torque and a fault coefficient of a hub motor through each vehicle-mounted sensor and each parameter observer; then determining whether the vehicle power system enters a fault state, and if the hub motor is in the fault state, entering a set fault-tolerant tracking link; and judging the fault mode of the current vehicle, using different control logics for different fault modes, and finally realizing fault-tolerant control or emergency risk avoiding of the vehicle. According to the present disclosure, aiming at different fault conditions of a power system of the distributed electric drive autonomous vehicle, different coping modes and control strategies are used for guaranteeing the stability and safety of the vehicle as much as possible, and the safety of passengers and goods is guaranteed.
Controller for internal combustion engine, control method for internal combustion engine, and memory medium
A controller for an internal combustion engine, a control method for an internal combustion engine, and a memory medium are provided. The controller executes a deactivation process that deactivates combustion control in a specified one of cylinders. A compensation process operates a power generation device that produces driving torque applied to a driven wheel so as to compensate for insufficiency of the driving torque of a vehicle caused by the deactivation process. A prohibition process prohibits the deactivation process when it is determined that compensation by a predetermined amount or larger by the compensation process cannot be performed.
VEHICLE CONTROL APPARATUS
A vehicle control apparatus includes a storage and a processor. The storage holds a first resonance map. The processor calculates a first torque command value that indicates a value of torque to be outputted by a first driving source. The first resonance map includes, as one or more first resonance points, one or more operating points at which resonance occurs in an operating region of the first driving source under a square wave control. The processor decreases or increases the first torque command value to avoid the one or more first resonance points on the condition that a predicted route of transition of an operating point of the first driving source meets the one or more first resonance points.
METHODS AND SYSTEM FOR ESTIMATING DRIVELINE TORQUE OF A HYBRID VEHICLE
Systems and methods for operating a hybrid powertrain that includes an engine and a motor/generator are described. The systems and methods align in time an estimated motor torque and an actual motor torque to provide an estimated driveline torque. The alignment compensates for communications delays between different controllers over a controller area network.
VEHICLE CONTROL DEVICE
A vehicle control device is configured to: execute a fuel cut control for stopping fuel supply to the internal combustion engine in response to a deceleration request to the vehicle; engage the lock-up clutch and open a throttle of the vehicle during the execution of the fuel cut control; close the throttle and execute the motor assist in a case where there is an acceleration request to the vehicle while the lock-up clutch is engaged, the throttle is opened, and the fuel cut control is executed; end the fuel cut control and resume fuel supply to the internal combustion engine when an intake pressure of the internal combustion engine reaches a predetermined startable negative pressure after the throttle is closed; and disengage the lock-up clutch when the fuel supply to the internal combustion engine is resumed.
Control method for vehicle, information processing device, and vehicle control system
A control method for a vehicle which is executable by at least one information processing device including a communication unit, includes: collecting vehicle information from the vehicle in a range of a communication data amount or a communication frequency that is allowed in communication with the vehicle, based on information about the communication data amount or the communication frequency; and calculating an accuracy of control of the vehicle based on an information amount of the collected vehicle information; and producing a control command based on the calculated accuracy.
Systems and methods for controlling energy generation in a hybrid powertrain
An apparatus includes an energy storage circuit, an input circuit, and a hybrid management circuit. The energy storage circuit is structured to receive a state of charge (SOC) and a state of health (SOH) of an energy storage device. The input circuit is structured to receive an indication of a torque demand. The hybrid management circuit is structured to determine a first torque output for a genset including an engine and a first motor-generator based on the torque demand and the SOC of the energy storage device; determine an adjustment factor based on the SOH of the energy storage device; determine an adjusted torque output for the genset based on the adjustment factor and the first torque output; operate the genset to provide the adjusted torque output and to generate an amount of energy; and operate a second motor-generator at a second torque output to meet the torque demand.
