Control system for a plug-in hybrid vehicle
A control system for a plug-in hybrid vehicle has a drive system having a starter motor, a transverse engine, and a motor/generator, and also has a power supply system having a high voltage battery; a capacitor; and a hybrid control module that controls charge and discharge of the capacitor. In the control system for an FF plug-in hybrid vehicle in which external charging of the high voltage battery is available, the hybrid control module starts the starter, performs a mode selection control and a charge/discharge control, maintains the capacitor voltage equal to or higher than a voltage that allows the starter to start-up when a CD mode is selected at the time of ignition ON, and maintains a capacitor voltage equal to or less than a voltage at which deterioration does not proceed at the time of ignition ON with the CS being selected.
Hybrid construction machine
The hybrid construction machine includes an engine 11, an electric motor/generator 14, a hydraulic pump unit 17, an electricity storage device 16, an inverter 15, a temperature regulator (16D or 16E), and a hybrid control unit 22. The hybrid control unit 22 executes at least one of first control for controlling a warming-up battery temperature regulator 16D so that it increases a temperature of the electricity storage device 16, second control for controlling the inverter 15 so that it reduces the power output from the inverter 15, and third control for controlling a pump capacity control unit 21 so that it reduces the flow rate of a hydraulic fluid delivered from the hydraulic pump unit 17, according to a charge/discharge history of the electricity storage device 16.
MULTIMODE CLUTCH FOR THROUGH-THE-ROAD HYBRID VEHICLE
A multimode clutch may be adapted for selectively connecting and disconnecting front and/or rear axles from respective internal combustion engine and electric motor powertrains connected to such front and rear driving axles in a through-the-road hybrid vehicle. For example, the engine may be part of a front axle driven powertrain connected to the front wheels, while the motor may be part of a separate rear axle driven powertrain connected to the rear wheels, or vice versa. By selective disconnection of an axle not being actively driven, a real time reduction in parasitic losses may be achieved, leading to higher overall operating efficiencies. The multimode clutch offers greater flexibility over the use of standard friction clutches; each multimode clutch may provide four distinct operational modes for accommodating a wide diversity of driving conditions. For example, bi-rotational freewheeling of the rear axle may occur whenever the motor is not in use.
HYBRID VEHICLE CONTROL DEVICE
A hybrid vehicle control device is provided that is capable of controlling a drive source according to a travel plan. The hybrid vehicle control device is configured to be mounted in a hybrid vehicle including a drive source having an engine and a motor/generator, and a navigation system that acquires travel environment information of a planned travel route. The control device is configured such that, upon selection of a “travel plan mode”, which controls the drive source according to a travel plan set for low fuel travel based on travel environment information acquired from the navigation system in the absence of the selection of an “eco-mode”, which controls the drive source to prioritize fuel efficiency over power performance, the selection of the “travel plan mode” is linked with a setting operation for the “eco-mode”.
Control system for hybrid vehicle
A control system for a hybrid vehicle configured to prevent a reduction in the purifying performance of the catalyst in a predetermined operating mode. An operating mode of the hybrid vehicle can be selected from a first hybrid vehicle mode, a second hybrid vehicle mode, and a fixed mode. A controller that is configured to restrict a shifting operation between the first hybrid vehicle mode and the second hybrid vehicle mode via the fixed mode, when the purifying device is being warmed or the purifying device has to be warmed.
Slope mower with safety features
Mowing systems include a mower and, optionally, a remote control unit such as a handheld unit, between which may be provided 1- or 2-way communications. Components and features are included in the mower, the remote control unit, or both to enhance the safety, functionality, or user experience of the system's user/operator. One aspect relates to monitoring a tilt angle of the mower, and defining or executing different system responses as a function of different first and second conditions that relate to the tilt angle. Another aspect relates to automatic adjustment of a speed setting of the mower's drive system as a function of a power takeoff (PTO) unit of the mower.
System and method for engine driveline disconnect during regeneration in hybrid vehicles
A system and method for operating a hybrid vehicle having an engine and an eMachine coupled by a clutch using a hybrid controller is presented. The method determines an idle fuel rate of the engine, determines a hybrid efficiency index for the hybrid vehicle, determines an expected energy storage rate increase for an operating condition where the engine is decoupled from a vehicle transmission using said clutch, multiplies the expected energy storage rate increase by the hybrid efficiency index to determine an expected fuel rate reduction of the engine in the operating condition; and decouples the engine from the vehicle transmission using the clutch if the expected fuel rate reduction is greater than the idle fuel rate.
Hybrid vehicle
An engine electronic control unit of a hybrid vehicle is configured to execute in-abnormality starting control for starting an engine when the engine is cranked in a state where abnormality occurs to communication between the engine electronic control unit and a hybrid electronic control unit. The hybrid electronic control unit is configured to execute in-abnormality cranking control for controlling the first motor such that the engine is cranked when the abnormality occurs to the communication between the engine electronic control unit and the hybrid electronic control unit. In addition, the hybrid electronic control unit is configured to execute in-abnormality electric travel control for controlling the second motor such that the hybrid vehicle travels only by power from the second motor when the in-abnormality cranking control is executed but the engine is not started.
Electro-hydraulic hybrid system
An electro-hydraulic hybrid system for a vehicle utilizes both the advantages of the hydraulic hybrid system and the electric hybrid system to maximize the collection of energy lost during a braking process and to provide launch assists in an acceleration process. The electro-hydraulic hybrid system includes an ECU that controls the electro-hydraulic hybrid system, a hydraulic drive pump, an accumulator, a hydraulic reservoir, a hydraulic pump, an electric motor, a power converter, and a battery. The hydraulic reservoir is in fluid communication with the accumulator through the hydraulic drive pump that functions as the main component of the hydraulic regenerative braking system. The hydraulic reservoir is also in fluid communication with the accumulator through the hydraulic pump that acts as the main component of the electro-hydraulic inter-conversion unit along with the electric motor, the at least one battery, and power converter that are electrically connected to each other.
SYSTEMS AND METHODS FOR VEHICLE SMART SEATS
A method comprises obtaining smart seat sensor data, the smart seat sensor data being detected by a tactile-sensitive surface material of a seat of an autonomous vehicle in response to a user interacting with the tactile-sensitive surface material. Other sensor data is obtained from one or more other sensors disposed within the autonomous vehicle. The smart seat sensor data and the other sensor data are integrated. A behavior of the user is estimated based on the integrated data, and the autonomous vehicle is controlled based on the estimated behavior of the user.
