A control apparatus of an electric vehicle includes a monitor determiner. The monitor determiner monitors a state of a main battery that supplies electric power directed to running, and determines whether the electric power of the main battery is usable on the basis of first information and second information. The first information is a deciding factor directed to deciding whether the electric power of the main battery is usable. The second information is a determination factor directed to determining whether the electric power of the main battery is usable. The monitor determiner determines, upon start-up of the electric vehicle, whether the electric power of the main battery is usable on the basis of the second information before the first information is calculated, and decides whether the electric power of the main battery is usable on the basis of the first information when the first information is calculated.

In an apparatus for controlling a driving system of a hybrid vehicle and a driving system control method thereof, the torque of an internal combustion driving system and the torque of an electric driving system in the hybrid vehicle are controlled according to the states of the internal combustion driving system and the electric driving system, so that the states of the driving systems in the hybrid vehicle may be maintained in balance, raising a residual value of the vehicle.

A system includes a hybrid power train comprising an internal combustion engine and electrical system, which includes a first and second electrical torque provider, and an electrical energy storage device electrically coupled to first and second electrical torque provider. The system further includes a controller structured to perform operations including determining a power surplus value of the electrical system; determining a machine power demand change value; in response to the power surplus value of the electrical system being greater than or equal to the machine power demand change value, operating an optimum cost controller to determine a power division for the engine, first electrical torque provider, and second electrical torque provider; and in response to the power surplus value of the electrical system being less than the machine power demand change value, operating a rule-based controller to determine the power division for the engine, first, and second electrical torque provider.

Systems and methods for restarting an engine are presented. In one example, an engine may be automatically stopped and started in response to thresholds that may be adjusted as a distance traveled by the vehicle increases. The thresholds may be adjusted responsive to useful life consumed of devices that may participate in automatic engine starting and stopping.

A system for providing a scale (11) of electrical charge of a vehicle battery and a hybrid vehicle comprising such a system comprises a scale (11) of state of charge of the vehicle battery. The scale (11) comprises minimum (14) and maximum (15) parameters and a controller to select the minimum (14) and maximum (15) parameters if the scale (11) in dependence on a battery usage parameter dependent on at least one of a mode of operation of the vehicle, a state of charge of the battery and a state of health of the battery. A display (10) for indicating an amount consists of the scale (11) and an indicator (12) movable with respect to the scale (11). Different scales (11) are provided for different purposes, and are changeable without altering the instant position of the indicator (12). The display (10) may indicate the state of charge of a battery of the hybrid electric vehicle having an internal combustion engine and motor/generator, different scales (11) having maxima (15) corresponding to different nominal or optimum states of charge.

An agricultural machine for conducting an agricultural working process includes a combustion engine (2), electrical consumers (3-8), a chargeable electrical battery (9) for electrically supplying the consumers (3-8) and a monitor module (10) for monitoring the charging level of the battery (9). It is proposed that some of the electrical consumers (3-8) of the agricultural machine (1) are peripheral consumers (3-8) for providing functions in a parking state of the agricultural machine (1), in which the combustion engine (2) is shut off, that a power management module (11) is provided, which in the parking state of the agricultural machine (1) monitors the charging level of the battery (9) via the monitor module (11) and deactivates at least one peripheral consumer (3-8), when the charging level falls below a threshold level.

Degradation degree table is a degradation degree table that describes a degradation degree of a secondary battery when the secondary battery is charged or discharged at a prescribed current rate with prescribed frequency. Degradation degree table describes the degradation degree in each of a plurality of state of charge (SOC) regions obtained through division of an SOC range of the secondary battery into the plurality of regions. Upper limit current determining part determines an upper limit current value to be used as a current rate at a time of charge or discharge, based on an estimated SOC and a target degradation degree with reference to degradation degree table.

A vehicle includes an electric power storage device, an electric motor, and an electronic control unit. The electronic control unit is configured to control charging and discharging of the electric power storage device such that a state of charge becomes a target state of charge, to determine whether or not a degree of deterioration of the electric power storage device due to unevenness in salt concentration is equal to or larger than a predetermined degree, when the degree of deterioration is equal to or larger than the predetermined degree and the state of charge is equal to or less than a predetermined requested state of charge, to set the target state of charge such that the target state of charge increases monotonically, and to set an increase amount or an increase rate of the monotonic increase to be larger as the degree of deterioration is larger.

A control apparatus of a hybrid vehicle which, when a travel mode is switched from a second mode (EV mode) to a first mode (series mode), can warm an exhaust purification catalyst appropriately to suppress deterioration of an exhaust gas, is provided. The control apparatus comprises selection means 32 which selects the first mode as a travel mode of a vehicle 10, if a required output is equal to or higher than a determination threshold value, or selects the second mode, if the required output is lower than the determination threshold value; and threshold value changing means 33 which lowers the determination threshold value, if the temperature of the exhaust purification catalyst is lower than a predetermined temperature.
