Apparatus and method for vehicle economy improvement
A method and apparatus is disclosed for evaluating the driving of a vehicle performing a journey on a road network, comprising determining at least one constant speed zone of the road network, a constant speed zone being a portion of the road network at which the vehicle can travel at a constant speed, said determination being based upon expected speeds of travel along the road network determined from positional data relating to the movements of a plurality of vehicles over time along the road network. A speed of the vehicle traversing the road network is determined at a plurality of times during the journey, and a value indicative of a consistency of the speed of the vehicle within the at least one constant speed zone is further determined.
Motor vehicle drivetrain controller
A method for controlling a drivetrain of a motor vehicle is disclosed. Either a start mode for starting the reciprocating engine is activated via the driving vehicle wheel, or a coasting mode is activated for driving the reciprocating engine via the driving vehicle wheel. At least one volume-reducing stroke is executed that follows an intake stroke for at least one cylinder of the reciprocating engine with at least intermittently open cylinder. Alternately at least one volume-enlarging stroke is executed for at least one cylinder of the reciprocating engine, which is followed by a compression stroke of this cylinder, and at least one volume-reducing stroke of this cylinder, which follows an expansion stroke that follows the compression stroke, with a cylinder that is closed, if possible, in this operating mode.
METHOD OF CONTROLLING A PRIME MOVER OF A VEHICLE, APPARATUS FOR CONTROLLING A PRIME MOVER OF A VEHICLE, AND A VEHICLE COMPRISING SUCH AN APPARATUS
Method and apparatus for controlling a prime mover of a first vehicle following a first path. A likely speed behaviour of a second vehicle ahead of the first vehicle is estimated based on a predicted path of the second vehicle. At least one coasting profile for the first vehicle is estimated for at least part of the first path and/or the predicted path. At least one of the coasting profiles is determined that meets at least one predetermined coasting requirement. The prime mover may be controlled to place the vehicle into a coasting mode based on the at least one determined coasting profile. Alternatively, feedback is provided to a user to put the vehicle into a coasting mode. The predetermined coasting requirement may include, for example, a minimum coasting mode period, a minimum coasting mode distance, a minimum coasting mode speed, a maximum coasting mode speed, or maintaining the first vehicle's speed with a predetermined tolerance of one or more desired speeds.
Vehicle control device and control method therefor
A vehicle control device includes control means for executing coasting control to disengage a friction engaging element and set a rotation speed of a rotary shaft of a drive source at zero when a predetermined condition is established, the predetermined condition including at least a condition according to which an accelerator pedal is not depressed. The control means starts the coasting control after predicting that an actual speed ratio of a continuously variable transmission will be modifiable to a target speed ratio of the coasting control during the coasting control, even in a case where the accelerator pedal is not depressed but the actual speed ratio has not yet reached the target speed ratio.
Coasting timer for predictive acceleration
Described herein are various embodiments for a coasting timer for predictive acceleration. In an embodiment, a system for predictive acceleration of a vehicle is described. The system may comprise an accelerator pedal; a sensor coupled to the accelerator pedal, the sensor configured to measure depression of the accelerator pedal; and an electronic control unit (ECU). The ECU may be configured to: determine a current coasting map; determine a coasting interval duration based, at least in part, on the current coasting map; determine the coasting interval duration has started based, at least in part, upon a measurement received from the sensor; and activate one or more subsystems of the vehicle prior to the end of the coasting interval duration, the one or more subsystems determined based, at least in part, on a predicted acceleration type.
Vehicle control apparatus
Provided is a control apparatus of a vehicle, which includes a transmission mode switching control program for controlling the automatic transmission to switch between an automatic transmission mode and a manual transmission mode, a coast idle stop control program for performing a coast idle stop control in which the engine is stopped automatically and the automatic transmission is changed into a neutral position while the vehicle is traveling, and a coast idle control program for performing a coast idle control in which the engine is made running idle and the automatic transmission is changed into the neutral position while the vehicle is traveling.
Vehicle control apparatus
A vehicle control apparatus for controlling a vehicle including an engine, a motor generator, a manual transmission, a clutch, an accelerator pedal, a clutch pedal, a brake pedal, a shift lever, and a control unit that performs inertia travel control to cause a vehicle to start inertia travel when a predetermined condition is satisfied during travel of the vehicle, performs free-run transition control to change to a free-run travel when a predetermined inertia travel time has elapsed since the start of the inertia travel, and sets the inertia travel time in a case where the last operation before the inertia travel is one of predetermined operation to be longer than the inertia travel time in a case where the last operation before the inertia travel is an operation in which the return speed of the accelerator pedal is greater than or equal to a predetermined return speed.
Vehicle control system
A vehicle control system to reduce shocks under an autonomous mode is provided. The vehicle control system is configured to select an operating mode of a vehicle from a manual mode in which a driving force and a braking force are controlled manually by a driver, and an autonomous mode in which the driving force and the braking force are controlled autonomously. A controller is configured to execute a fuel cut-off control, and a threshold selected under the autonomous mode is set in such a manner as to terminate the fuel cut-off control earlier than under the manual mode.
CONTROLLING EATS TEMPERATURE
In an aspect, a computer system is provided comprising processing circuitry configured to acquiring information indicating a temperature of an exhaust aftertreatment system, EATS, of a vehicle, maintaining a current gear of the vehicle in response to the vehicle approaching a downhill slope and the acquired information indicating that the temperature should be increased, and decreasing speed of an engine of the vehicle for causing engine braking in the downhill slope, while maintaining a speed of the vehicle within a set vehicle speed range.
Vehicle Control Device
An engine is driven at an operating point with high engine efficiency to improve fuel economy. A vehicle control device according to the present invention controls a transmission ratio before increasing the engine rotation speed, and thereafter, engages the clutch.
