A vehicle which can improve fuel consumption without a driver feeling uncomfortable is provided. The vehicle includes: a hydraulic pressure sensor for acquiring a brake torque value which increases in accordance with a stepping-in amount of a brake pedal by the driver, and an ECU which automatically stops an engine after a basic time has elapsed since a basic condition is satisfied and then automatically restarts the engine. The ECU automatically stops the engine before the basic time elapses, when an increment of the brake torque value from a reference value after the basic condition is satisfied is equal to or greater than an additional stepping judgment value, and a shortened time shorter than the basic time has elapsed.

A vehicle engine automatic control device has a brake operation amount detecting unit that detects an amount of brake operation by a driver, an engine stopping/re-starting unit that, during coast drive, stops an engine based on the amount of brake operation that is detected, and, after the engine stops, re-starts the engine when the amount of brake operation that is detected falls below a first threshold, and a first threshold setting unit that sets the first threshold smaller as vehicle speed becomes lower.

A technique for simplifying the structure of an idling stop device. The idling stop device 100 includes a deceleration detector 200 which detects decelerations of a vehicle. The idling stop device 100 also includes an estimation part 350 which acquires, based on the deceleration detected by the deceleration detector 200, first deceleration when a vehicle is decelerated to a preset speed of less. Based on the acquired first deceleration, the estimation part 350 estimates a first brake pressure applied to the vehicle when the vehicle is decelerated to the preset speed or less.

The present disclosure relates to an ISG control system and an ISG control method for a construction machine capable of controlling ISG even in a working state of a construction machine, the ISG control system including: a surrounding environment determinator configured to determine surrounding environment of the construction machine; and a vehicle controller configured to determine whether the construction machine is in a working state or a traveling state based on a determination result from the surrounding environment determinator, wherein the vehicle controller controls an engine based on a preset work ISG condition when it is determined that the construction machine is in the working state, and wherein the vehicle controller controls the engine based on a preset travel ISG condition when it is determined that the construction machine is in the traveling state.

A vehicle equipped with an automatic stop/restart system for an internal combustion engine includes a hydraulic continuously variable transmission and a parking mechanism. The continuously variable transmission changes power of the internal combustion engine using hydraulic pressure boosted by rotational driving force of the internal combustion engine. The parking mechanism holds the vehicle stationary by locking, with a locking member, the rotation of a power transmitting member between the internal combustion engine and driving wheels when a shift position is in a parking range. In an automatic stop state of the internal combustion engine, when the shift position is in the parking range and brakes are turned off, an electronic control unit executes restart if an inclination angle of the vehicle is greater than or equal to a predetermined value, and maintains the automatic stop state if the inclination angle is smaller than the predetermined value.

A vehicle system and method for remote start operation in the vehicle system are provided. The method includes responsive to receiving a remote start request and while the vehicle is stationary, automatically engaging a wheel-arresting device coupled to a wheel in the vehicle. The method also includes when an electronically actuated clutch is automatically disengaged and subsequent to the automatic engagement of the wheel-arresting device, implementing remote start operation in an engine, where the wheel-arresting device is distinct from a secondary vehicle brake.

Disclosed are a vehicle and an engine control method for more conveniently restarting an engine in the state in which a function of automatically turning off the engine is activated during braking for improving fuel efficiency. The engine control method includes turning off an engine through an idle stop and go (ISG) system during braking due to manipulation of a brake pedal, determining whether at least one preset starting condition is satisfied based on information on a forward environment, and turning on the engine irrespective of whether manipulation of the brake pedal is released when any one of the at least one starting condition is satisfied.

A battery and supercapacitor system of a vehicle includes a lithium ion battery (LIB) disposed within a housing. The LIB includes: an electrolyte including lithium; and first and second electrodes disposed in the electrolyte. A supercapacitor is disposed within the housing and includes: the electrolyte; and third and fourth electrodes disposed in the electrolyte.

Systems and methods for operating an engine that may selectively enter and exit a fuel cut-off mode are described. In one example, the method holds the engine in the fuel cut-off mode even though a propulsive effort pedal is applied. An electric machine may provide torque to a vehicle driveline while the engine is in the fuel cut-off mode.

Systems and methods for operating an engine that may be selectively automatically stopped and started are described. In one example, the method adjusts an amount of time that the engine may be inhibited from automatically stopping based on driver inputs such as driver demand pedal position, vehicle speed, and braking torque.
